Description

Measurement report transmission method, terminal equipment and access network equipment

Technical Field

The embodiment of the application relates to the field of communication, and in particular relates to a measurement report transmission method, terminal equipment and access network equipment.

Background

Quality of experience (QoE) is a performance index used to evaluate the user's overall subjective perception of quality and performance (including availability and availability) of a device, network, system, application, or service, and may be defined from the comfort of the service application. Measuring the quality of experience is called QoE measurement (also called application layer measurement). Application layer measurement may also refer to the quality and performance of the reporting device, application or service by the terminal device. The operator knows the user experience status by collecting QoE measurement results (also referred to as application layer measurement results), and further optimizes the network better to improve the user experience.

In the current application layer measurement process, the access network device sends the application layer measurement configuration to the terminal device, and the terminal device measures the service according to the application layer measurement configuration to obtain an application layer measurement report corresponding to the service. Whenever a terminal device measures an application layer measurement report, the terminal device sends the application layer measurement report to the access network device. Therefore, the current scheme for transmitting the application layer measurement report is too high in signaling overhead.

Disclosure of Invention

The embodiment of the application provides a measurement report transmission method, terminal equipment and access network equipment, and reduces signaling overhead for transmitting an application layer measurement report between the terminal equipment and the access network equipment.

In a first aspect, the present application provides a measurement report transmission method, which relates to a terminal device and an access network device. In the method, a terminal device acquires time information. The time information indicates the timing of encapsulating the application layer measurement report, and the application layer measurement report is the measurement result obtained by the terminal device performing application layer measurement. Then, the terminal device encapsulates at least one application layer measurement report into the first message according to the time information. The terminal device then sends the first message to the access network device.

The time information indicates an occasion of encapsulating the application layer measurement report, and it can be understood that the terminal device may directly or indirectly determine the occasion of encapsulating the application layer measurement report according to the time information, that is, the terminal device may directly or indirectly determine at what time instant one or more application layer measurement reports are encapsulated into the first message according to the time information, so as to send the one or more application layer measurement reports to the access network device through the first message.

In addition, in the application layer measurement process, the terminal device needs to obtain the application layer measurement configuration from the access network device, and then performs the application layer measurement based on the application layer measurement configuration, so as to obtain the application layer measurement report (i.e. the measurement result obtained by performing the application layer measurement by the terminal device). The application layer measurement configuration may be received by the access network device from a core network element, or may be generated by the access network device. Furthermore, an application layer measurement configuration generally corresponds to an exact service type, i.e. an application layer measurement configuration is used to measure the service of a certain service type.

Further, the first message refers to a message capable of encapsulating one or more application layer measurement reports. The first message refers to a message in a broad sense, and in some possible scenarios, the first message may also be referred to as a first signaling, a first packet, a first data packet, a first command, and the like.

In this embodiment, when obtaining the application layer measurement report, the terminal device can refer to the time information to decide whether to encapsulate the obtained application layer measurement report in the first message or encapsulate the obtained multiple application layer measurement reports in the first message. Because the terminal equipment decides the time for packaging one or more application layer measurement reports based on the time information, the flexibility of reporting the application layer measurement reports to the access network equipment by the terminal equipment is improved. Further, when the terminal device determines to encapsulate multiple application layer measurement reports into the first message and sends the first message to the access network device, signaling used for transmitting the application layer measurement reports between the terminal device and the access network device can be saved, and the utilization rate of the signaling used for transmitting the application layer measurement reports is improved.

In a possible implementation, the encapsulating, by the terminal device, at least one application layer measurement report into the first message according to the time information includes: and the terminal equipment encapsulates at least two application layer measurement reports into a first message according to the time information, wherein each application layer measurement report in the at least two application layer measurement reports corresponds to a different service type respectively.

In this embodiment, it is proposed that the terminal device is capable of encapsulating at least two application layer measurement reports respectively corresponding to different service types in one message (i.e., the first message). For example, an application layer measurement report obtained by measuring a service of a first service type and an application layer measurement report obtained by measuring a service of a second service type are encapsulated in the first message.

In a possible implementation, the encapsulating, by the terminal device, at least one application layer measurement report into the first message according to the time information includes: and the terminal equipment encapsulates at least two application layer measurement reports into a first message according to the time information, wherein each application layer measurement report in the at least two application layer measurement reports corresponds to the same service type.

In this embodiment, it is proposed that the terminal device is capable of encapsulating at least two application layer measurement reports corresponding to the same service type in one message (i.e., the first message). Optionally, the at least two application layer measurement reports are obtained by the terminal device at different time instants. For example, the terminal device obtains an application layer measurement report about the first service type every T milliseconds, and then the terminal device may encapsulate the application layer measurement report obtained at time T and the application layer measurement report obtained at time (T + T) in the aforementioned first message.

In a possible implementation, the encapsulating, by the terminal device, at least one application layer measurement report into the first message according to the time information includes: the terminal equipment encapsulates at least three application layer measurement reports into a first message according to the time information, wherein the at least three application layer measurement reports not only comprise at least two application layer measurement reports belonging to a first service type, but also comprise at least one application layer measurement report belonging to a second service type. Wherein the first traffic type is different from the second traffic type.

In this embodiment, it is proposed that the terminal device is capable of encapsulating at least three application layer measurement reports in one message (i.e. the aforementioned first message). The at least three application layer measurement reports not only have application layer measurement reports corresponding to different service types, but also have a plurality of application layer measurement reports corresponding to the same service type.

In a possible embodiment, the time information comprises a first encapsulation period indicating a period for encapsulating at least one application layer measurement report into one message. Specifically, the encapsulating, by the terminal device, at least one application layer measurement report into a first message according to the time information includes: the terminal equipment encapsulates the application layer measurement report obtained in the first encapsulation period to the first message. That is, the terminal device triggers an encapsulating application layer measurement report every other duration corresponding to the first encapsulating period. It is also understood that a timing device (e.g., a timer) is disposed in the terminal device, and the timing device sets the duration of the first packaging period. When the timing device is running, the terminal device may obtain one or more application layer measurement reports, the terminal device may receive the application layer measurement reports until the timing device times out, and the terminal device triggers encapsulation of the obtained application layer measurement reports into the first message. Certainly, after the terminal device sends the first message, if the access network device does not provide a new encapsulation period to the terminal device, or the terminal device does not obtain a new encapsulation period from another channel, the terminal device resets the timing device to zero and times again, and receives an application layer measurement report obtained subsequently (i.e., an application layer measurement report obtained after the first message is sent), and when the timing device times out again, the terminal device triggers to encapsulate the application layer measurement reports obtained after the first message is sent into one message together, and sends the message to the access network device. So that the cycle will not be described again.

It should be noted that, in this embodiment, the multiple application layer measurement reports obtained by the terminal device in the first encapsulation period may be application layer measurement reports corresponding to different service types, may also be multiple application layer measurement reports corresponding to the same service type, and may also include both of the foregoing two cases, which is not limited herein.

In a possible implementation manner, the time information includes at least one measurement period, and each measurement period is used to instruct the terminal device to obtain a time interval of two adjacent application layer measurement reports corresponding to the same service type.

Optionally, each measurement period in the at least one measurement period corresponds to one service type, and the service types corresponding to each measurement period are not completely the same.

In one possible embodiment, the time information comprises a plurality of measurement periods. The terminal device encapsulates at least one application layer measurement report into a first message according to the time information, and the method comprises the following steps: the terminal equipment determines a second packaging period according to a plurality of measurement periods, wherein the second packaging period is used for indicating the period of packaging at least one application layer measurement report into one message; the terminal device encapsulates the application layer measurement report measured in the second encapsulation period to the first message.

In this embodiment, the terminal device can determine the second packaging period based on the plurality of measurement periods, and the role of the second packaging period is similar to the role of the first packaging period described above. In this embodiment, the second encapsulation period is determined by the terminal device based on a plurality of measurement periods, and the first encapsulation period is provided by the access network device to the terminal device.

Optionally, the second encapsulation periods are respectively greater than at least two measurement periods. At this time, the terminal device can obtain at least two application layer measurement reports in one second encapsulation period.

In one possible embodiment, the time information comprises a plurality of measurement periods. The terminal device encapsulates at least one application layer measurement report into a first message according to the time information, and the method comprises the following steps: the terminal equipment acquires a start instruction corresponding to each service type, wherein the start instruction is used for instructing to trigger and measure the service of the service type; after the terminal equipment obtains one application layer measurement report, the terminal equipment determines whether to generate a first message for encapsulating at least one application layer measurement report according to the starting instructions of the multiple service types and the measurement periods of the multiple service types.

In this embodiment, after obtaining one application layer measurement report, the terminal device determines whether another application layer measurement report can be measured in a short time in the future according to the start instructions of multiple service types and the measurement periods of multiple service types. If the terminal device can measure other application layer measurement reports in a short time in the future, the terminal device determines not to generate a first message for encapsulating at least one application layer measurement report; if no other application layer measurement reports exist within a short time in the future, the terminal device will determine to generate a first message encapsulating at least one application layer measurement report.

Optionally, each generation time corresponds to an application layer measurement report. Optionally, the multiple generation times are times when the terminal device measures the application layer measurement reports of different service types.

In this embodiment, it is proposed that the terminal device can determine when the application layer measurement report corresponding to a certain service type is to be measured according to a start instruction of the service type and a measurement period of the service type. By analogy, when the terminal device calculates the generation time of the multiple application layer measurement reports, the terminal device knows whether the application layer measurement report can be measured in a future period of time, and further determines whether to wait for the next measured application layer measurement report.

In a possible implementation, the terminal device determines whether to generate a first message encapsulating at least one application layer measurement report according to a plurality of generation times, including: the terminal equipment determines the packaging number according to a plurality of generating moments, wherein the packaging number is used for indicating the number of the application layer measurement reports packaged in one message; when the number of the application layer measurement reports obtained by the terminal equipment reaches the packaging number, the terminal equipment packages the obtained multiple application layer measurement reports into the first message.

In this embodiment, it is proposed that after the terminal device determines a plurality of generation times, the terminal device may determine the number of packages, that is, which application layer measurement reports with the generation times being relatively close to each other are packaged into the first message together, that is, the number of application layer measurement reports carried in the first message. At this time, a counting means (e.g., a counter) may be provided in the terminal device. After determining the number of packages, the terminal device starts the counting device, and counts once every application layer measurement report is obtained until the number of packages is reached. Then, the terminal device encapsulates the obtained plurality of application layer measurement reports into the aforementioned first message.

In one possible embodiment, the method further comprises: when the terminal equipment determines to generate a first message for encapsulating at least one application layer measurement report, the terminal equipment encapsulates the obtained application layer measurement report into the first message; when the terminal device determines not to generate a first message encapsulating at least one application layer measurement report, the terminal device waits to receive a next application layer measurement report.

After the terminal device 01 obtains the application layer measurement report based on the application layer measurement configuration, the terminal device 01 needs to report the application layer measurement report to the access network device 021, so that the access network device 021 forwards the application layer measurement report to a device (e.g., a tracking area code (TCE) or a Measurement Collection Entity (MCE)) responsible for collecting the application layer measurement report.

Since the terminal device immediately sends the application layer measurement report to the access network device every time it obtains an application layer measurement report (or called as encapsulating the application layer measurement report into a message every time it obtains an application layer measurement report), it may cause that the terminal must immediately send the application layer measurement report to the access network device even when it sets up an inappropriate time, and thus the terminal device cannot flexibly report the application layer measurement report. In addition, there are a plurality of services in a terminal device, and when application layer measurement is required for each service of the terminal device, there will be a large amount of signaling for transmitting application layer measurement reports between the terminal device and the access network device. Therefore, the current scheme for transmitting the application layer measurement report will also consume the signaling overhead between the terminal device and the access network device.

Therefore, the application provides a measurement report transmission method, a terminal device and an access network device, which can improve the flexibility of reporting an application layer measurement report to the access network device by the terminal device, and reduce the signaling overhead for transmitting the application layer measurement report between the terminal device and the access network device. Please refer to the embodiment corresponding to fig. 2 hereinafter.

It should be noted that the terminal devices to which the present application relates include devices that provide voice and/or data connectivity to a user. For example, a handheld device with wireless connection capability or a processing device connected to a wireless modem may be included.

Further, the terminal device may be a vehicle-mounted terminal, for example, a vehicle-mounted Box (T-Box), a Domain Controller (DC), a Multi Domain Controller (MDC), or a vehicle-mounted unit (OBU) integrated in a vehicle. The terminal device may also be a wearable device, such as glasses, gloves, watches, clothing and shoes, or another portable device that may be worn directly on the body or integrated into the clothing or accessories of the user.

In this embodiment and the following embodiments, only the terminal device is taken as an example for description.

In addition, the access network device related to the present application is an access network device (RAN) that currently provides a service for the terminal device, and may be a 4G wireless access network device, or a device that communicates with the wireless terminal device through one or more cells on an air interface in a 4G access network. For example, the access network device may be an LTE base station, and may also be referred to as an evolved node B (NodeB) or eNB or e-NodeB in a long term evolution LTE system or an evolved LTE system (LTE-a). The access network device may be configured to interconvert a received air frame with an Internet Protocol (IP) packet as a router between the terminal device and the rest of the access network, where the rest of the access network may include an IP network.

It should be understood that the access network device in the embodiment of the present application may be any one of the above devices or a chip in the above devices, and is not limited herein. The access network device, whether as a device or as a chip, may be manufactured, sold, or otherwise used as a stand-alone product. In this embodiment and the following embodiments, only the access network device is taken as an example for description.

The following describes a main flow of the measurement report transmission method proposed in the present application with reference to fig. 2, in which the terminal device and the access network device mainly perform the following steps:

step 201, the terminal device acquires time information.

Wherein the time information indicates an occasion for encapsulating the application layer measurement report, it may be understood that the terminal device may directly or indirectly determine the occasion for encapsulating the application layer measurement report according to the time information, that is, the terminal device may directly or indirectly determine at what time instant one or more application layer measurement reports are encapsulated into one message (hereinafter, the message in which at least one application layer measurement report is encapsulated is referred to as a first message) according to the time information, so as to transmit the aforementioned one or more application layer measurement reports to the access network device through the aforementioned first message. It should be noted that, in the present application, the terminal device encapsulates one or more application layer measurement reports into one message as an example. In practical applications, the solution proposed in this application may also be extended to a terminal device encapsulating one or more application layer measurement reports into a data packet of a user plane.

In addition, the application layer measurement report is a measurement result obtained by the terminal device performing application layer measurement. Generally, after receiving an application layer measurement configuration from an access network device, a terminal device triggers application layer measurement based on the application layer measurement configuration to obtain the application layer measurement report. The application layer measurement configuration may be received by the access network device from a Core Network (CN), an operation, administration and maintenance (OAM) or an Element Manager (EM) (specifically, refer to step 401a in the embodiment corresponding to fig. 4, or step 501a in the embodiment corresponding to fig. 5); or may be generated by the access network device (specifically, refer to step 401b in the embodiment corresponding to fig. 4, or step 501b in the embodiment corresponding to fig. 5).

In addition, an application layer measurement configuration generally corresponds to an exact service type, that is, an application layer measurement configuration is used for measuring a service of a certain service type, and further obtaining an application layer measurement report corresponding to the service type. The service type may be streaming service (streaming service), voice service, multimedia Telephony Service (MTSI) of an IP multimedia system, virtual Reality (VR) service, augmented Reality (AR) service, multicast and Broadcast Service (MBS), and the like. Therefore, when the terminal device receives the application layer measurement configuration, the terminal device can also receive the service type corresponding to the application layer measurement configuration. Generally, the application layer measurement configuration and the service type corresponding to the application layer measurement configuration are encapsulated in the same message and sent to the terminal device. Therefore, when a terminal device obtains a certain application layer measurement configuration (e.g., application layer measurement configuration 1) and a certain service type (e.g., service type 1) from a message, the terminal device can determine that the application layer measurement configuration 1 is used for measuring the service corresponding to the service type 1, and after the terminal device measures the service corresponding to the service type 1 based on the application layer measurement configuration 1, an application layer measurement report corresponding to the service type 1 can be obtained.

Specifically, the terminal device has multiple time information acquisition modes:

in an alternative embodiment, the terminal device receives time information from the access network device. The access network device is also an access network device that provides the aforementioned application layer measurement configuration and service type for the terminal device. In a specific implementation, the access network device may send the application layer measurement configuration and the time information to the terminal device through different messages respectively; the access network device may also send the application layer measurement configuration, the service type, and the time information to the terminal device through the same message, which is not limited herein.

In addition, the time information received by the terminal device from the access network device may be received by the access network device from a network element such as a core network CN, an operation, administration, and maintenance OAM, or an element management EM (specifically, refer to step 401a in the embodiment corresponding to fig. 4, or step 501a in the embodiment corresponding to fig. 5); or may be generated by the access network device (specifically, refer to step 401b in the embodiment corresponding to fig. 4, or step 501b in the embodiment corresponding to fig. 5).

In a further alternative embodiment, the terminal device determines the time information itself. Optionally, the terminal device receives an application layer measurement configuration from the access network device, where the application layer measurement configuration includes time information. For example, the application layer measurement configuration received by the terminal device includes some parameters (e.g., measurement period) related to time or period, and the terminal device determines the aforementioned parameters (e.g., measurement period) as time information. Optionally, the terminal device generates the time information according to some received (or existing) parameters (e.g. measurement period) related to time or period. For example, the terminal device generates a period for encapsulating the application layer measurement report according to the measurement period (hereinafter referred to as an encapsulation period, for example, a second encapsulation period and a third encapsulation period which will be described later), which is time information generated by the terminal device. Certainly, in practical applications, the terminal device may also generate the time information in other manners or based on other parameters, and the specific application is not limited.

Specifically, the specific implementation forms of the time information acquired by the terminal device are multiple:

In another possible implementation, the time information includes at least one measurement period, and each measurement period is used to instruct the terminal device to obtain a time interval between two adjacent application layer measurement reports corresponding to the same service type. Note that the measurement period may also be referred to as a reporting period or a reporting interval (report interval).

In another possible embodiment, the time information comprises an encapsulation amount, which may be understood as the number of application layer measurement reports encapsulated in one first message.

When the terminal device obtains the time information and obtains one or more application layer measurement reports by performing measurement based on the application layer measurement configuration, the terminal device will execute step 202.

Step 202, the terminal device encapsulates at least one application layer measurement report into a first message according to the time information.

Wherein the first message refers to a message capable of encapsulating one or more application layer measurement reports. The first message refers to a message in a broad sense, and in some possible scenarios, the first message may also be referred to as a first signaling, a first packet, a first data packet, a first command, and the like. Illustratively, the first message may be a Radio Resource Control (RRC) message. Optionally, when the size of the first message exceeds a certain threshold (for example, the first message is an RRC message, and the size of the first message exceeds a packet size that can be carried by a Packet Data Convergence Protocol (PDCP) layer at maximum), the terminal device may segment or segment the first message to generate a plurality of segmentation or segmentation messages, where each segmentation or segmentation message carries a part of content in the first message, and each segmentation or segmentation message carries a sequence number of a segmentation or segmentation, and indicates whether the current segmentation or segmentation message is the last segmentation or segmentation of the first message.

It should be noted that, if a plurality of application layer measurement reports are encapsulated in the first message, the plurality of application layer measurement reports may be application layer measurement reports corresponding to different service types, may also be a plurality of application layer measurement reports corresponding to the same service type, and may also include both the foregoing cases. At this time, the first message further includes a service type corresponding to the one or more application layer measurement reports. The following analyses were carried out separately:

in a possible implementation manner, the terminal device encapsulates at least two application layer measurement reports into the first message according to the time information, where each of the at least two application layer measurement reports corresponds to a different service type. For example, one application layer measurement report 1 obtained by measuring the service of the service type 1 and one application layer measurement report 2 obtained by measuring the service of the service type 2 are encapsulated in the aforementioned first message.

In another possible implementation manner, the terminal device encapsulates at least two application layer measurement reports into the first message according to the time information, where each of the at least two application layer measurement reports corresponds to the same service type. Optionally, the at least two application layer measurement reports are obtained by the terminal device at different time points respectively. For example, the terminal device obtains an application layer measurement report on the service type 1 every T milliseconds, and then the terminal device may encapsulate the application layer measurement report 1 on the service type 1 obtained at the time T and the application layer measurement report 2 on the service type 1 obtained at the time (T + T) in the aforementioned first message.

In another possible implementation, the terminal device encapsulates at least three application layer measurement reports into the first message according to the time information, where the at least three application layer measurement reports include not only at least two application layer measurement reports belonging to the first service type, but also at least one application layer measurement report belonging to the second service type. Wherein the first traffic type is different from the second traffic type. For example, assume that the terminal device obtains an application layer measurement report for traffic type 1 every T milliseconds, and obtains an application layer measurement report for traffic type 2 every 2T milliseconds. At this time, if the terminal device obtains an application layer measurement report 1 regarding service type 1 at time T, and obtains an application layer measurement report 2 regarding service type 1 and an application layer measurement report 3 regarding service type 2 at time (T + T), then the terminal device may make a decision based on the time information such that the foregoing application layer measurement report 1, application layer measurement report 2, and application layer measurement report 3 are encapsulated together in a message to be sent to the access network device.

In the above description, from the perspective of the number of application layer measurement reports that may be encapsulated in the first message, how the terminal device encapsulates the application layer measurement report into the first message based on the time information will be described below based on a specific implementation of the time information. It should be understood that if the specific implementation of the time information is different, the implementation of the terminal device encapsulating the application layer measurement report into the first message based on the time information is also different. The following are introduced separately:

in a possible embodiment, the time information comprises a first encapsulation period indicating a period for encapsulating at least one application layer measurement report into one message. The first encapsulation period may be directly sent to the terminal device by the access network device, or may be determined by the terminal device based on application layer measurement configuration, which is not limited herein.

Specifically, the terminal device encapsulates the application layer measurement report obtained in the first encapsulation period to the first message. That is, every other time duration corresponding to the first encapsulation period, the terminal device triggers an encapsulation application layer measurement report, that is, the application layer measurement report obtained in the first encapsulation period is encapsulated into the first message.

Illustratively, a timing device (e.g., a timer) is disposed in the terminal device, and the timing device sets the duration to be the first packaging period. Optionally, the terminal device may start the timing apparatus after receiving the application layer measurement configuration, or may start the timing apparatus after starting the application layer measurement. When the timing device is running, the terminal device may obtain one or more application layer measurement reports, the terminal device may measure and obtain the application layer measurement reports until the timing device is overtime, and the terminal device triggers to encapsulate the obtained application layer measurement reports into the first message. Certainly, after the terminal device sends the first message, if the access network device does not provide a new encapsulation period to the terminal device, or the terminal device does not obtain a new encapsulation period from another channel, the terminal device resets the timing device to zero and times again, and receives an application layer measurement report obtained subsequently (i.e., an application layer measurement report obtained after the first message is sent), and when the timing device times out again, the terminal device triggers to encapsulate the application layer measurement reports obtained after the first message is sent into one message together, and sends the message to the access network device. So that the cycle will not be described again.

It should be noted that, in this embodiment, the multiple application layer measurement reports obtained by the terminal device in the first encapsulation period may be application layer measurement reports corresponding to different service types, may also be multiple application layer measurement reports corresponding to the same service type, or may include both of the foregoing cases, which is not limited herein.

It should also be understood that the present embodiment does not require that the application layer measurement report obtained by the terminal device is periodically measured, that is, the application layer measurement report obtained by the terminal device for a certain service type may be measured according to a certain period, or the terminal device may not exhibit a periodic rule when measuring the application layer measurement report.

For ease of understanding, reference will now be made to FIG. 3A as an example. As shown in fig. 3A, a case where the terminal device obtains application layer measurement reports of three service types respectively is enumerated, where each upright arrow represents an application layer measurement report of one terminal device, the length of each dashed box in the horizontal direction (which may also be referred to as the length in the time axis direction) represents one first encapsulation period (i.e., encapsulation period 01, encapsulation period 02, encapsulation period 03 are all examples of the aforementioned first encapsulation period), and the black arrow falling in the dashed box represents an application layer measurement report to be encapsulated into one message (i.e., the aforementioned first message). As can be seen from the example shown in fig. 3A: the terminal equipment obtains an application layer measurement report of the service type 1 according to the measurement period T1; the terminal equipment obtains an application layer measurement report of a service type 3 according to a measurement period T2; the terminal device does not measure the application layer measurement report of the service type 2 according to the periodic rule, that is, the application layer measurement report of the service type 2 obtained by the terminal device does not exhibit the periodic rule. At this time, if the terminal device encapsulates the first encapsulation period according to the received first encapsulation period, the terminal device may encapsulate two application layer measurement reports, which are respectively different service types, in the encapsulation period 01 into one message; the terminal device may encapsulate three application layer measurement reports of different service types in the encapsulation period 02 into one message; the terminal device may encapsulate four application layer measurement reports in the encapsulation period 03 into one message, and there are two application layer measurement reports that both belong to service type 1. In practical applications, further examples are possible, and are not specifically listed here.

In another possible implementation manner, the time information includes at least one measurement period, where each measurement period is used to instruct the terminal device to obtain a time interval of two adjacent application layer measurement reports corresponding to the same service type. Optionally, each measurement period in the at least one measurement period corresponds to one service type, and the service types corresponding to each measurement period are not completely the same. Still taking the aforementioned fig. 3A as an example, T1 in fig. 3A represents a measurement period for measuring an application of the service type 1, that is, every two application layer measurement reports of the service type 1 obtained by the terminal device will have a gap of T1.

Specifically, the terminal device may calculate an encapsulation period (e.g., a second encapsulation period, a third encapsulation period, etc., which will be described later) using the aforementioned measurement period, where the encapsulation period is used to indicate a period for encapsulating at least one application layer measurement report into one message; the terminal device may also calculate the number of packages indicating the number of application layer measurement reports encapsulated in one message using the aforementioned measurement period. The following are introduced separately:

in a possible embodiment, the time information includes a plurality of measurement periods, and the terminal device determines a second encapsulation period according to the plurality of measurement periods, the second encapsulation period being used to indicate a period for encapsulating at least one application layer measurement report into one message; the terminal device encapsulates the application layer measurement report obtained in the second encapsulation period to the first message. Optionally, the second encapsulation periods are respectively greater than at least two measurement periods. At this time, the terminal device can obtain at least two application layer measurement reports in one second encapsulation period. In this embodiment, the terminal device can determine the second encapsulation period based on the plurality of measurement periods, and the role of the second encapsulation period is similar to that of the first encapsulation period described above. In this embodiment, the first encapsulation period is determined by the terminal device based on a plurality of measurement periods, and the second encapsulation period is determined by the access network device.

In particular, when the time information includes only one measurement period, an encapsulation period (hereinafter referred to as a third encapsulation period to be distinguished from the second encapsulation period in the foregoing) determined by the terminal device may encapsulate a plurality of application layer measurement reports into one message. For example, it is assumed that the terminal device obtains an application layer measurement report about the service type 1 every T0 milliseconds, that is, the measurement period of the terminal device is T0, and the third encapsulation period determined by the terminal device according to the measurement period T0 is 2 times T0. At this time, the terminal device may encapsulate the application layer measurement report 1 on the traffic type 1 obtained at the time T and the application layer measurement report 2 on the traffic type 1 obtained at the time (T + T0) together in the first message.

In another possible implementation, the terminal device needs to obtain, in addition to the multiple measurement periods, a start indication corresponding to each service type, where the start indication is used to indicate that application layer measurement of the service type is triggered. Then, after the terminal device obtains an application layer measurement report, the terminal device determines whether to generate a first message encapsulating at least one application layer measurement report according to the starting indications of the multiple service types and the measurement periods of the multiple service types. If the terminal device determines to generate a first message encapsulating at least one application layer measurement report, the terminal device encapsulates the obtained application layer measurement report(s) into the first message, otherwise, the terminal device continues to wait for the next application layer measurement report.

For ease of understanding, fig. 3B is described as an example below. As shown in fig. 3B, the case that the terminal device obtains the application layer measurement reports of three service types respectively is enumerated, wherein the first arrow of each time axis represents the start indication, and the following arrow represents the application layer measurement report of one terminal device. The terminal equipment obtains application layer measurement reports of a service type 4 and a service type 5 according to a measurement period T3; and the terminal equipment obtains the application layer measurement report of the service type 6 according to the measurement period T4. At this time, after the terminal device obtains the first application layer measurement report (assumed to be application layer measurement report 001), the terminal device determines whether to trigger generation of the first message (i.e., determines whether to trigger generation of the first message encapsulating one or more application layer measurement reports) according to the measurement period and start indication of traffic type 4, the measurement period and start indication of traffic type 5, and the measurement period and start indication of traffic type 6. If the terminal device determines to continue waiting for the next application layer measurement report, i.e. not to trigger generation of the first message for the moment, when the terminal device measures the second application layer measurement report (assumed to be application layer measurement report 002), the terminal device will again determine whether to generate the first message. If the terminal equipment determines to generate the first message immediately, the terminal equipment encapsulates the obtained application layer measurement reports (an application layer measurement report 001 and an application layer measurement report 002) into the first message together; if the terminal device determines to continue waiting for the next application layer measurement report, i.e. not to trigger generation of the first message temporarily, when the terminal device measures the third application layer measurement report (assumed to be the application layer measurement report 005), the terminal device will determine again whether to generate the first message. If the terminal equipment determines to generate the first message immediately, the terminal equipment encapsulates the obtained application layer measurement reports (the application layer measurement report 001, the application layer measurement report 002 and the application layer measurement report 005) into the first message; if the terminal equipment determines to continue waiting for the next application layer measurement report, the generation of the first message is not triggered temporarily. And so on, and will not be described in detail herein.

Specifically, the determining, by the terminal device, whether to wait for a specific implementation of a next application layer measurement report (which may also be understood as a specific implementation of determining, by the terminal device, whether to generate the first message) includes:

and the terminal equipment determines the generation time of the application layer measurement report corresponding to the service type based on the starting indication and the measurement period of the same service type, wherein the generation time is used for indicating the theoretical time of measuring or obtaining the application layer measurement report by the terminal equipment. The terminal device then determines whether to generate a first message encapsulating at least one application layer measurement report according to the plurality of generation instants. Optionally, each generation time corresponds to an application layer measurement report. Optionally, the multiple generation times are times when the terminal device measures the application layer measurement reports of different service types. In this embodiment, it is proposed that the terminal device can determine when the application layer measurement report corresponding to a certain service type is to be measured according to a start instruction of the service type and a measurement period of the service type. By analogy, when the terminal device calculates the generation time of the plurality of application layer measurement reports, the terminal device knows whether other application layer measurement reports can be measured in a future period of time, and further determines whether to wait for the next measured application layer measurement report.

For ease of understanding, still taking fig. 3B as an example for description, the terminal device can determine that the generation time of the application layer measurement report 001 and the generation time of the application layer measurement report 002 are both the time t2 according to the measurement period and the start instruction of the service type 4, the measurement period and the start instruction of the service type 5, and the measurement period and the start instruction of the service type 6. At this point, the terminal device will determine that application layer measurement report 001 and application layer measurement report 002 should be obtained at time t2 to trigger generation of the first message. Similarly, the terminal device may also determine, through calculation, that the generation times of the application layer measurement report 003, the application layer measurement report 004, and the application layer measurement report 005 are all the time t3, and then the terminal device determines that the generation of the first message is triggered only when the application layer measurement report 003, the application layer measurement report 004, and the application layer measurement report 005 are obtained at the time t 3. And so on, and will not be described in detail.

Further, the step of determining, by the terminal device according to the multiple generation moments, whether to generate the first message encapsulating the at least one application layer measurement report includes: the terminal equipment determines the packaging number according to a plurality of generating moments, wherein the packaging number is used for indicating the number of the application layer measurement reports packaged in one message; when the number of the obtained application layer measurement reports of the terminal device reaches the packaging number, the terminal device packages the obtained application layer measurement reports into the first message. That is, after the terminal device determines a plurality of generation times, the terminal device may determine the number of packages, that is, which application layer measurement reports with the generation times being closer to each other are packaged into the first message together, that is, the number of application layer measurement reports carried in the first message. At this time, a counting means (e.g., a counter) may be provided in the terminal device. After determining the number of packages, the terminal device starts the counting device, and counts once every application layer measurement report is obtained until the number of packages is reached. Then, the terminal device encapsulates the obtained multiple application layer measurement reports into the first message.

For ease of understanding, still referring to fig. 3B as an example, it is assumed that the measurement period T4 is equal to 2 times T3, and the three traffic types start to be measured at time T1. The terminal device can determine that the terminal device will obtain 2 application layer measurement reports (i.e. application layer measurement report 001 and application layer measurement report 002) 1 time T3 after T1 time according to the measurement period and start indication of service type 4, the measurement period and start indication of service type 5, and the measurement period and start indication of service type 6, i.e. determine that the number of packages at T2 time is 2; it can also be determined that 3 application layer measurement reports (i.e., application layer measurement report 003, application layer measurement report 004, and application layer measurement report 005) are obtained 2 times T3 after time T1, i.e., the number of packages at time T3 is determined to be 3. And so on, and will not be described in detail.

In a possible embodiment, the time information comprises an encapsulation quantity, which can be understood as the number of application layer measurement reports encapsulated in one first message. For example, the terminal device may set a counting device (e.g., a counter) according to the number of the packages, and after the terminal device starts the counting device, the terminal device counts each time an application layer measurement report is obtained until the number of the packages is reached. Then, the terminal device encapsulates the obtained plurality of application layer measurement reports (i.e. the number of application layer measurement reports indicated by the aforementioned encapsulation amount) into the aforementioned first message.

In one possible embodiment, the time information comprises a package size indicating a total size of an application layer measurement report triggering the packaging of one message. For example, if the encapsulation size is 2M, when the size of the application layer measurement report obtained by the terminal device is greater than or equal to 2M, the terminal device encapsulates the obtained application layer measurement report into a message.

It should be understood that the foregoing implementations of various temporal information may be combined with each other.

For example, the time information may include both the packing period (e.g., the first packing period) and the packing number. For example, the terminal device starts a timing device with a duration of a first encapsulation period, and before the timing device times out, if the number of application layer measurement reports obtained by the terminal device reaches a certain threshold (for example, the aforementioned threshold is N, that is, the number of application layer measurement reports reaches N), the terminal device may encapsulate the obtained N application layer measurement reports into one message (for example, one first message). Meanwhile, the terminal equipment also sets the timing device to zero and counts time again. When the timing device times out, the terminal device can also trigger to encapsulate a plurality of application layer measurement reports received by the terminal device into one message (for example, another first message). The threshold may be a value sent by the access network device to the terminal device; the threshold may also be fixed to a value, for example, a fixed value specified in the protocol; the aforementioned threshold value may also be determined by the terminal device itself.

For example, the aforementioned time information may include both a package period (e.g., the aforementioned first package period) and a package size. For example, the terminal device starts a timing device with a first encapsulation period, and before the timing device times out, if the total size of the application layer measurement reports obtained by the terminal device exceeds a certain threshold #1 (for example, the aforementioned threshold #1 is 2M, and the total size of the application layer measurement reports obtained by the terminal device is 2.1M), the terminal device may encapsulate the obtained application layer measurement report (possibly one application layer measurement report or multiple application layer measurement reports) into a message (for example, a first message). Meanwhile, the terminal equipment also sets the timing device to zero and counts again. When the timing device times out, the terminal device can also trigger to encapsulate a plurality of application layer measurement reports received by the terminal device into one message (for example, another first message). The threshold #1 may be sent to the terminal device by the access network device; the threshold #1 may also be fixed to a value, for example, a fixed value specified in the protocol; the threshold #1 may also be determined by the terminal device itself.

In a possible implementation manner, the terminal device can further determine the time information according to the start indication corresponding to each service type. For example, the terminal device determines the time information according to the time of the start instruction corresponding to each service type. For example, the terminal device obtains a deviation of the time of the start instruction corresponding to each service type, and if the deviation of the time of the start instruction corresponding to two service types is within a certain range, the terminal device may wait for an application layer measurement report corresponding to another service type when obtaining the application layer measurement report corresponding to the first service type. Otherwise, the terminal device does not need to wait for the measurement result of the application layer corresponding to another service type, that is, the terminal device can generate a message.

In this application, the terminal device may generate the first message by using any one of the foregoing implementation manners, which is not limited herein.

Step 203, the terminal device sends a first message to the access network device. Accordingly, the access network device receives the first message from the terminal device.

In this embodiment, after the terminal device generates the first message, the terminal device sends the first message to the access network device. In this case, the first message may include one application layer measurement report or may include a plurality of application layer measurement reports. Compared with the conventional technology, in the solution of the conventional technology, the terminal device sends the application layer measurement report to the access network device every time the terminal device obtains the application layer measurement report, without referring to other information (e.g., time information provided by the present application), and without considering encapsulating multiple application layer measurement reports into one message (because the terminal device cannot know when which service type of application layer measurement report will be measured). Therefore, in the application, the terminal device can decide the time for encapsulating one or more application layer measurement reports based on the time information, so that the flexibility of reporting the application layer measurement reports to the access network device by the terminal device is improved. Further, when the terminal device determines to encapsulate multiple application layer measurement reports into the first message and sends the first message to the access network device, signaling used for transmitting the application layer measurement reports between the terminal device and the access network device can be saved, and the utilization rate of the signaling used for transmitting the application layer measurement reports is improved. It should be noted that the access network device that sends the application layer measurement configuration to the terminal device and the access network device that receives the application layer measurement report from the terminal device may not be the same access network device, and may also be the same access network device. For example, the access network device #1 transmits the application layer measurement configuration to the terminal device. Due to the mobility of the terminal device, the terminal device may be handed over from access network device #1 to access network device #2. At this time, the terminal device can transmit an application layer measurement report to the access network device #2.

In addition, it should be noted that the time information acquired by the terminal device may be time information generated specifically for reporting the application layer measurement report, for example, time information generated by a network element such as the core network CN, the operation, administration and maintenance OAM, or the element management EM when generating the application layer measurement configuration, or time information generated by the access network device when generating the application layer measurement configuration. The time information may also be time-related information originally applied to other processing flows, but the embodiment uses the time information to decide whether to generate the first message. For example, the application layer measurement configuration would carry a measurement period, which the terminal device just uses to decide whether to generate the first message. For another example, the access network device needs to set other configurations to the terminal device, and the configurations happen to have information of the measurement period measured by the application layer, and the terminal device happens to use the measurement period to decide whether to generate the first message. Of course, the present application does not exclude the role of the time information in other technical solutions, and the present application only introduces the role of the time information in the solution of the present application.

Furthermore, in one possible implementation, the application layer measurement report includes an application layer measurement indicator recognizable by the access network device and/or an application layer measurement report unrecognizable by the access network device.

Among them, the application layer measurement report unrecognizable by the access network device is generally located in a container (container) (or referred to as an application layer measurement report carried in a container or encapsulated in a first message), and therefore, the application layer measurement report unrecognizable by the access network device is often referred to as a QoE measurement report container (QoE measurement report container). Generally, an application layer measurement report of one service type is encapsulated in one container. Since the access network device does not unpack the container after obtaining the container encapsulating the application layer measurement report, the application layer measurement report that is not actively unpacked and identified by the access network device encapsulated in the container is referred to as an application layer measurement report that is not identifiable by the access network device. Furthermore, the application layer measurement configuration corresponding to the application layer measurement report unrecognizable by the access network device is also an application layer measurement configuration unrecognizable by the access network device, and the application layer measurement configuration unrecognizable by the access network device is also transmitted to the terminal device by being encapsulated in a container, so the application layer measurement configuration unrecognizable by the access network device is often referred to as a QoE measurement configuration container (QoE measurement configuration container).

In addition, the application layer measurement indicator that can be recognized by the access network device may also be understood as an application layer measurement report (RAN-visible QoE report) (or referred to as an application layer measurement report, which is not carried or encapsulated in the first message in the form of a container, but is in other forms, such as in the form of an Information Element (IE)), where the application layer measurement indicator that can be recognized by the access network device is a measurement result of an application layer measurement configuration that can be recognized and used by the access network device. Corresponding to the application layer measurement report (RAN-visible QoE report) that can be recognized by the access network device is a QoE configuration (RAN-visible QoE configuration) that can be recognized by the access network device.

It should be noted that, in the foregoing embodiment, one application layer measurement report may be replaced by one QoE measurement report container (QoE measurement report container), one application layer measurement report (RAN-visible QoE report) recognizable by the access network device, or a combination of the QoE measurement report container (QoE measurement report container) and the application layer measurement report (RAN-visible QoE report) recognizable by the access network device. That is, if a terminal device needs to send a QoE measurement report container (QoE measurement report container) and a RAN-visible QoE report (RAN-visible QoE report) that can be recognized by an access network device to the access network device at the same time, the terminal device sends the QoE measurement report container (QoE measurement report container) and the RAN-visible QoE report that can be recognized by the access network device to the access network device in one message. In this case, the QoE measurement report container (QoE measurement report container) corresponding to the same service, which is obtained by the terminal device at the same time, and the application layer measurement report (RAN-visible QoE report) that can be recognized by the access network device may be regarded as one application layer measurement report. That is, an application layer measurement report obtained by a terminal device measuring a service of a certain service type may include: the application layer measurement report which is not recognizable by the access network equipment encapsulated in the container and the application layer measurement report which is recognizable by the access network equipment positioned outside the container.

In addition, the terms "recognizable" and "detectable" may also be referred to herein as "perceptible," "interpretable," "acquaintable," and "detectable," and are not limited herein.

The foregoing measurement report transmission method will be further described with reference to fig. 4. As shown in fig. 4, the aforementioned time information comes from the access network side. In this flow, the UE is an implementation manner of the terminal device in the embodiment corresponding to fig. 2, the RAN is an implementation manner of the access network device in the embodiment corresponding to fig. 2, and the message 1 is an implementation manner of the first message in the embodiment corresponding to fig. 2. The UE is divided into an access layer of the UE and an application layer of the UE. The method comprises the following specific steps:

in step 401a, the cn sends application layer measurement configuration, traffic type and time information to the RAN.

The service type corresponds to the application layer measurement configuration, that is, the service type is a type of a service for performing application layer measurement according to the application layer measurement configuration, and it can also be understood that the service type is used for specifying the type of the application layer measurement. The application layer measurement configuration may be an application layer measurement configuration that can be recognized by the access network device, that is, a RAN-visible QoE configuration that can be recognized by the access network device; or may be an application layer measurement configuration unrecognizable by the access network device, that is, a QoE measurement configuration container (QoE measurement configuration container); it is also possible to include application layer measurement configurations that are recognizable by the access network device and application layer measurement configurations that are not recognizable by the access network device.

Illustratively, the application-layer measurement configuration recognizable by the access network device includes at least one of: some Metrics (Metrics) or indexes that the terminal device needs to measure and report; the range of the terminal device performing the application layer measurement, for example, the time range, the start time, the duration, and the like of the measurement; the reporting policy of the terminal device, for example, the measurement period or the reporting interval, the sampling ratio, the location filtering configuration, and the like. The sampling proportion refers to whether the terminal device reports the QoE measurement result or performs the QoE measurement, and the terminal device determines whether to report the QoE measurement result or perform the QoE measurement by using a random number generator and the sampling proportion. Location filtering configuration refers to which areas the terminal device is in for QoE measurements.

The aforementioned metrics or indicators include at least one of: average throughput: refers to the total number of bits received by the application layer of the UE during a measurement interval. E.g., average throughput in streaming media traffic. Reference may be made in particular to the definition in section 10.2 of the 3GPP protocol TS 26.247. Initial play delay: refers to the initial playback delay for beginning presentation of the streaming media. For example, it may be specifically defined from the time of acquiring the first segment of media to the time of extracting the streaming media from the client buffer. Reference may be made in particular to the definition in section 10.2 of the 3GPP protocol TS 26.247. Buffer level: refers to the time during which the media data will continue to be played from the current play time. Reference may be made in particular to the definition in section 10.2 of the 3GPP protocol TS 26.247. This is not specifically listed here.

Optionally, the application layer measurement configuration, the service type, and the time information that are not recognizable by the access network device in this step may be located in QOE measurement configuration information (QOE measurement configuration information). For example, the QOE measurement configuration information (QOE measurement configuration information) includes one QOE measurement configuration container (QOE measurement configuration container), the service type (service type) other than the container, and time information other than the container. In addition, the QOE measurement configuration information (QOE measurement configuration information) also includes a region range of QOE Measurement Collection (QMC). The QMC region includes: a Cell ID List (Cell ID List), a tracking area List (TA List) of QMC, a tracking area identity List (TAI List), and the like.

In addition, for the explanation of the time information and the service type, reference may be made to step 201 described above, which is not described herein in detail.

It should be noted that in this step, a Core Network (CN) element may be replaced by an operation, administration and maintenance (OAM) or Element Manager (EM) element, or another element capable of generating an application layer measurement configuration. For example, for signaling-based QoE measurement, it is the CN that sends application layer measurement configuration, traffic type, and time information to the RAN; for management-based QoE measurement, it is OAM or EM that sends application layer measurement configuration, traffic type, and time information to the RAN.

In step 401b, the ran generates application layer measurement configuration, traffic type and time information.

In this step, the RAN can generate application layer measurement configuration, traffic type, and time information in some cases.

In this embodiment, step 401b is an optional step. When the RAN performs step 401a, the RAN will not perform step 401b; when the RAN performs step 401b, the RAN will not perform step 401a. The details are not limited herein.

In step 402, the ran sends application layer measurement configuration, traffic type, and time information to the access layer of the UE.

For the signaling-based QoE measurement, the RAN may decide whether to configure QoE measurement for the UE according to whether the UE supports QoE measurement and the area coverage of QMC in the QoE measurement configuration information. And when the UE supports QoE measurement and the UE is currently in the area range of QMC, the RAN sends the application layer measurement configuration to the corresponding UE. For the management-based QoE measurement, the RAN selects an appropriate UE for QoE measurement according to whether the UE supports QoE measurement, the area coverage of QMC in the QoE measurement configuration information, and other factors. After the RAN selects the UE, the RAN sends the measurement configuration of the application layer to the UE.

Optionally, the RAN sends the application layer measurement configuration, the service type, and the time information to the UE through an RRC message. It should be noted that the RAN may send the application layer measurement configuration and the time information to the access layer of the UE through two RRC messages, respectively, or may send the application layer measurement configuration and the time information through one message at the same time. The RRC message for the RAN to send the application layer measurement configuration may carry one application layer measurement configuration, or may carry multiple application layer measurement configurations (for example, application layer measurement configurations for different service types). In addition, the sent application layer measurement configuration information may be for the UE to perform application layer measurement in an RRC IDLE state (RRC _ IDLE) or an RRC INACTIVE state (RRC _ INACTIVE), or may be for the UE to perform application layer measurement in an RRC CONNECTED state (RRC _ CONNECTED), which is not limited herein.

It should be understood that, in addition to sending the application layer measurement configuration unrecognizable by the access network device to the UE, the RAN may also issue a RAN-visible QoE configuration (RAN-visible QoE configuration) recognizable by the access network device to the UE, so as to notify the UE of reporting the measurement value of the application layer measurement indicator and/or the evaluation value of the application layer measurement indicator in a form (such as an information element form) that can be perceived by the RAN. Wherein the measurement value of the application layer measurement indicator is a result that the RAN can recognize about the application layer indicator measurement. The evaluation value of the application layer measurement index is a comprehensive score of an application layer index recognizable by the RAN, or a comprehensive score of an access layer index, or a comprehensive score obtained by combining the application layer index and the access layer index, or a value indicating the quality of the application layer index (for example, the value may be good, medium, or poor).

In step 403, the access stratum of the UE sends the application layer measurement configuration and the traffic type to the application layer of the UE.

In this step, the application layer of the UE may also be replaced with a layer capable of performing QOE measurement, and the layer capable of performing QOE measurement is located between the access layer of the UE and the application layer of the UE. For example, the UE defines a module dedicated to QoE measurement within its own module, which is located between the access stratum of the UE and the application stratum of the UE. In this embodiment and the following embodiments, only the application layer of the UE is taken as an example for description.

In this step, the access layer of the UE stores the time information and sends the application layer measurement configuration and the service type to the application layer of the UE. Wherein, the application layer measurement configuration comprises an application layer measurement configuration which can be identified by the RAN and/or an application layer measurement configuration which can not be identified by the RAN.

Optionally, the access layer of the UE sends the application layer measurement configuration and the service type to the application layer of the UE through an authentication command (AT command). Optionally, the password command is specifically AT command + CAPPLEVMC (command application level measurement configuration). One AT command + CAPPLEVMC can carry one or more application layer measurement configurations corresponding to one service type, and can also carry a plurality of application layer measurement configurations corresponding to different service types.

In this embodiment, the access stratum of the UE may carry multiple application layer measurement configurations through one password command (AT command), or may carry multiple application layer measurement configurations through multiple password commands (for example, one password command carries only one application layer measurement configuration).

In step 404, the application layer of the ue measures the service corresponding to the service type according to the application layer measurement configuration.

In this step, after the application layer of the UE receives the application layer measurement configuration and the service type, the application layer of the UE measures the service of the service type by using the application layer measurement configuration to obtain an application layer measurement report corresponding to the service type.

Optionally, when the application layer of the UE receives the application layer measurement configuration and the service corresponding to the service type is started, the UE starts the corresponding application layer measurement. When the application layer of the UE starts measurement, the application layer of the UE sends a start instruction to the access layer of the UE, where the start instruction is used to indicate that the application layer measurement corresponding to a certain session corresponding to the aforementioned service type starts. The start indication includes information corresponding to the application layer measurement initiation. The information corresponding to the measurement start of the application layer comprises one of the following items: the service type corresponding to the application layer measurement that the UE has started, the application layer measurements of which slices (slices) in the service type have started (for example, carrying single network slice selection assistance information (S-NSSAI)), and a recording session indication (received session indication). The recording session indication is the same in the whole process of a certain session, and different sessions correspond to different recording session indications, that is, the application layer of the UE allocates different recording session indications to different sessions.

Optionally, when the service corresponding to the service type is ended, the UE may end the corresponding application layer measurement. When the application layer of the UE finishes the application layer measurement, the application layer of the UE sends an end instruction to the access layer of the UE, where the end instruction is used to indicate that the application layer measurement corresponding to a certain session corresponding to the service type is finished. The end indication includes information corresponding to the end of the application layer measurement. The information corresponding to the end of the application layer measurement includes one of the following items: the application layer measurement that the UE has ended corresponds to the service type, which slices of the service type have ended (for example, carrying S-NSSAI), and a recording session indication (recorded session indication).

Step 405, the application layer of the UE sends an application layer measurement report to the access layer of the UE.

Wherein, the application layer of the UE sends the application layer measurement report to the access layer of the UE according to a certain rule (for example, the rule is included in the application layer measurement configuration). For example, the application layer of the UE may periodically send the application layer measurement report to the access layer of the UE, that is, the application layer of the UE sends the application layer measurement report to the access layer of the UE according to the measurement period. For example, the application layer of the UE may send an application layer measurement report to the access layer of the UE after a session ends.

It should be noted that the application layer of the UE may carry multiple application layer measurement reports through one password command, or may carry multiple application layer measurement reports through multiple password commands (for example, one password command carries only one application layer measurement report).

It should be noted that, when the application layer of the UE sends an application layer measurement report to the access layer of the UE, the application layer of the UE may indicate a service type corresponding to the application layer measurement report, so that when the application layer measurement report of the UE is reported to the RAN, the RAN can know which service type the application layer measurement report corresponds to.

It should also be noted that the aforementioned application layer measurement report may be an application layer measurement report recognizable by the RAN, e.g., a RAN-visible QoE report; or an application layer measurement report unrecognizable to the RAN, e.g., qoE measurement report container.

In step 406, the access stratum of the ue determines whether to wait for the next application layer measurement report according to the time information.

In this embodiment, the access layer of the UE determines whether to wait for the next application layer measurement report according to the time information, which may also be understood as that the access layer of the UE determines whether to generate the message 1 according to the time information.

In a possible embodiment, the time information comprises a first encapsulation period indicating a period for encapsulating at least one application layer measurement report into one message. The access stratum of the UE encapsulates the application layer measurement report received in the first encapsulation period to message 1. That is, every other time duration corresponding to a first encapsulation period, the access stratum of the UE triggers an encapsulation application layer measurement report, that is, the application layer measurement report obtained in the first encapsulation period is encapsulated in the message 1.

Illustratively, a timer (timer) is set in the access stratum of the UE, and the duration of the timer is set to be the aforementioned first encapsulation period. When the timer runs, the access stratum of the UE may receive one or more application layer measurement reports from the application layer of the UE, and the access stratum of the UE may receive the application layer measurement reports until the timer times out, and then the access stratum of the UE triggers encapsulation of the received application layer measurement reports into message 1. After the access stratum of the UE sends the message 1, the access stratum of the UE sets the timer to zero and re-counts, and receives a subsequent received application layer measurement report (i.e., an application layer measurement report received after the message 1 is sent), and when the timer times out again, the access stratum of the UE triggers to encapsulate the application layer measurement reports received after the message 1 is sent into one message together, and sends the message to the access network device. So that the cycle will not be described again.

In another possible implementation, the time information includes at least one measurement period, and each measurement period is used to instruct an access stratum of the UE to obtain a time interval of two adjacent application layer measurement reports corresponding to the same service type. Optionally, each measurement period in the at least one measurement period corresponds to one service type, and the service types corresponding to each measurement period are not completely the same. Specifically, the access stratum of the UE may calculate an encapsulation period (e.g., a second encapsulation period, a third encapsulation period, etc.) using the aforementioned measurement period, where the encapsulation period is used to indicate a period for encapsulating at least one application layer measurement report into one message; the access stratum of the UE may also calculate the number of encapsulations, which is used to indicate the number of application layer measurement reports encapsulated in one message, using the aforementioned measurement period.

In another possible embodiment, the time information comprises an encapsulation amount, which may be understood as the number of application layer measurement reports encapsulated in one first message. For example, the access stratum of the UE may set a counting device (e.g., a counter) according to the aforementioned number of packages, and after the access stratum of the UE starts the aforementioned counting device, the access stratum of the UE counts once every time it receives an application layer measurement report from the application layer of the UE until the number of application layer measurement reports received by the access stratum of the UE reaches the aforementioned number of packages. Then, the access stratum of the UE encapsulates the obtained multiple application layer measurement reports (i.e. the number of application layer measurement reports indicated by the aforementioned encapsulated quantity) into the aforementioned message 1.

In another possible embodiment, the time information comprises an encapsulation size indicating a total size of an application layer measurement report triggering encapsulation of one message. For example, if the encapsulation size is 2M, when the size of the application layer measurement report obtained by the access stratum of the UE is greater than or equal to 2M, the access stratum of the UE encapsulates the obtained application layer measurement report into a message 1.

In another possible implementation, the access stratum of the UE is further capable of determining the time information according to the start indication corresponding to each service type. For example, the access stratum of the UE determines the time information according to the time of the start instruction corresponding to each service type. For example, the access layer of the UE obtains a deviation of a time of a start instruction corresponding to each service type, and if the deviation of the time of the start instruction corresponding to two service types is within a certain range, the access layer of the UE may wait for an application layer measurement report corresponding to another service type when the access layer of the UE obtains an application layer measurement report corresponding to a first service type. Otherwise, the access layer of the UE does not wait for the measurement result of the application layer corresponding to another service type, that is, the access layer of the UE may generate a message.

It should be understood that the foregoing implementations of various temporal information may be combined with each other. Specifically, please refer to the related description in step 202, which is not repeated herein.

In this application, the access stratum of the UE may determine whether to wait for the next application layer measurement report by using any one of the foregoing implementation manners, which is not limited herein. Specifically, please refer to the related description in step 202 in the corresponding embodiment of fig. 2, which is not repeated herein.

Specifically, when the access stratum of the UE determines that it is not necessary to wait for the next application layer measurement report, the obtained multiple application layer measurement reports are encapsulated into the message 1, i.e. step 407 is triggered to be executed. When the access layer of the UE determines that it needs to wait for the next application layer measurement report, then the access layer of the UE will continue to receive the next application layer measurement report from the application layer of the UE.

In step 407, the access stratum of the ue encapsulates the received multiple application layer measurement reports into message 1.

It should be noted that, if a plurality of application layer measurement reports are encapsulated in the message 1, the plurality of application layer measurement reports may be application layer measurement reports corresponding to different service types, may also be a plurality of application layer measurement reports corresponding to the same service type, and may also include both the foregoing cases. Illustratively, the access stratum of the UE encapsulates at least two application layer measurement reports into the message 1 according to the time information, where each of the at least two application layer measurement reports corresponds to a different service type. Illustratively, the access stratum of the UE encapsulates at least two application layer measurement reports into the message 1 according to the time information, where each of the at least two application layer measurement reports corresponds to the same service type. Optionally, the at least two application layer measurement reports are obtained by the access layer of the UE at different time points. Illustratively, the access stratum of the UE encapsulates at least three application layer measurement reports into the message 1 according to the time information, the at least three application layer measurement reports including not only at least two application layer measurement reports belonging to the first traffic type but also at least one application layer measurement report belonging to the second traffic type. Wherein the first traffic type is different from the second traffic type. Specifically, please refer to the related description in step 202 in the corresponding embodiment of fig. 2, which is not repeated herein.

Optionally, the plurality of application layer measurement reports are encapsulated into an application layer measurement report element (MeasReportAppLayer IE), and the application layer measurement report element MeasReportAppLayer IE is encapsulated in the message 1. Optionally, the message 1 is an RRC message.

In step 408, the access stratum of the ue sends a message 1 encapsulating a plurality of application layer measurement reports to the RAN.

In step 409, the ran sends a message 1 encapsulating a plurality of application layer measurement reports to a tracking area code (TCE).

In this embodiment, step 409 is an optional step.

In some embodiments, the aforementioned tracking area code (TCE) may be replaced with a Measurement Collection Entity (MCE), and may also be replaced with other entities having a measurement result collection function.

In this embodiment, the access layer of the UE can forward the application layer measurement configuration and the service type from the RAN side to the application layer of the UE, so that the application layer of the UE performs application layer measurement. The access stratum of the UE then receives application layer measurement reports from the application layer of the UE, and the access stratum of the UE is also able to decide the timing of encapsulating one or more application layer measurement reports based on the time information from the RAN side. Therefore, the flexibility of reporting the application layer measurement report to the RAN by the UE is improved. Further, the UE determines to encapsulate multiple application layer measurement reports into the message 1, and sends the message 1 to the RAN, which can save signaling used for transmitting the application layer measurement reports between the UE and the RAN and improve the utilization rate of the signaling used for transmitting the application layer measurement reports.

As shown in fig. 5, the aforementioned time information is determined by the UE based on information provided by the RAN or determined by the UE itself based on other information. Wherein, the UE is an implementation of the terminal device, the RAN is an implementation of the access network device, and the message 1 is an implementation of the first message. The UE is divided into an access layer of the UE and an application layer of the UE. The method comprises the following specific steps:

in step 501a, the cn sends the application layer measurement configuration and the traffic type to the RAN.

The service type corresponds to the application layer measurement configuration, that is, the service type is a type of a service for performing application layer measurement according to the application layer measurement configuration, and it can also be understood that the service type is used for specifying the type of the application layer measurement. The application layer measurement configuration may be an application layer measurement configuration that can be recognized by the access network device, that is, a RAN-visible QoE configuration that can be recognized by the access network device; or may be an application layer measurement configuration unrecognizable by the access network device, that is, a QoE measurement configuration container (QoE measurement configuration container); and may also contain application layer measurement configurations that are recognizable by the access network equipment and application layer measurement configurations that are not recognizable by the access network equipment. For the application layer measurement configuration that the access network device can recognize and the application layer measurement configuration that the access network device cannot recognize, reference may be made to the related description in step 201, which is not described herein again.

In addition, for the explanation of the service type, reference may be made to the foregoing step 201, which is not described herein in detail.

It should be noted that in this step, a Core Network (CN) element may be replaced by an operation, administration and maintenance (OAM) or Element Manager (EM) element, or other elements capable of generating an application layer measurement configuration. For example, for signaling-based QoE measurement, it is the CN that sends application layer measurement configuration, traffic type, and time information to the RAN; for management-based QoE measurement, it is OAM or EM that sends application layer measurement configuration, traffic type, and time information to the RAN.

In step 501b, the ran generates an application layer measurement configuration and a traffic type.

In this step, the RAN can generate an application layer measurement configuration and a traffic type in some cases.

It should be noted that in this embodiment, the time information is not carried in step 501a and step 501 b. It is also understood that, in the QOE measurement configuration information (QOE measurement configuration information), there is no information explicitly used as time information other than the QOE measurement configuration container (QOE measurement configuration container). In this embodiment, the time information used by the UE is determined by the UE based on information provided by the RAN, specifically refer to step 505.

In this embodiment, step 501b is an optional step. When the RAN performs step 501a, the RAN will not perform step 501b; when the RAN performs step 501b, the RAN will not perform step 501a. The details are not limited herein.

In step 502, the RAN sends the application layer measurement configuration and traffic type to the access stratum of the UE.

Optionally, the RAN sends the application layer measurement configuration and the service type of the access network device to the UE through an RRC message. It should be noted that the RAN may send the application layer measurement configuration and the traffic type to the access layer of the UE through two RRC messages, respectively, or may send the application layer measurement configuration and the traffic type through one message at the same time. The RRC message sent by the RAN for the application layer measurement configuration may carry one application layer measurement configuration or may carry multiple application layer measurement configurations (e.g., application layer measurement configurations for different service types). In addition, the sent application layer measurement configuration information may be for the UE to perform application layer measurement under RRC _ IDLE/RRC _ INACTIVE, or may be for the UE to perform application layer measurement under RRC _ CONNECTED, which is not limited herein.

It should be understood that, in addition to sending the application layer measurement configuration unrecognizable by the access network device to the UE, the RAN may also issue a RAN-visible QoE configuration (RAN-visible QoE configuration) recognizable by the access network device to the UE, so as to notify the UE of reporting the measurement value of the application layer measurement indicator and/or the evaluation value of the application layer measurement indicator in a form (such as an information element form) that can be perceived by the RAN. Specifically, please refer to the related description in step 402, which is not limited herein.

Step 503, the access layer of the UE sends the application layer measurement configuration and the service type to the application layer of the UE.

Step 503 is similar to step 403, and please refer to the related description in step 403, which is not described herein again.

In step 504, the application layer of the ue measures the service corresponding to the service type according to the application layer measurement configuration.

Step 504 is similar to step 404, and please refer to the related description in step 404, which is not described herein again.

In step 505, the application layer of the ue generates time information.

In one possible embodiment, the application layer measurement configuration received by the UE from the RAN includes time information. For example, the application layer measurement configuration received by the application layer of the UE includes some parameters (e.g., measurement period) related to time or period, and the application layer of the UE determines the parameters (e.g., measurement period) as the time information.

Further, in a possible implementation manner, the application layer measurement configuration includes at least one measurement period, where each measurement period is used to indicate a time interval for the UE to obtain two adjacent application layer measurement reports corresponding to the same service type. Optionally, each measurement period in the at least one measurement period corresponds to one service type, and the service types corresponding to each measurement period are not completely the same. The terminal device determines at least one measurement period in the aforementioned application layer measurement configuration as time information.

In another possible embodiment, the application layer of the UE generates the time information according to some received (or existing) parameters (e.g. measurement period) related to time or period. For example, the application layer of the UE generates a package period for packaging the application layer measurement report according to the measurement period, where the package period is time information generated by the UE.

Further, in a possible embodiment, the application layer of the UE obtains at least one measurement period from the application layer measurement configuration, or obtains at least one measurement period from other configuration information. Wherein, each measurement period is used to instruct the UE to obtain a time interval of two adjacent application layer measurement reports corresponding to the same service type. Optionally, each measurement period in the at least one measurement period corresponds to one service type, and the service types corresponding to each measurement period are not completely the same. Then, the application layer of the UE may calculate an encapsulation period (e.g., a second encapsulation period, a third encapsulation period, etc.) indicating a period for encapsulating at least one application layer measurement report into one message using the aforementioned measurement period. The application layer determined time information of the UE includes the encapsulation period.

In a possible embodiment, the application layer of the UE may generate the time information according to other information, which is not limited in this application.

It should be noted that there is no explicit chronological restriction between step 504 and step 505. That is, the application layer of the UE may perform step 504 before step 505, may perform step 505 before step 504, or may perform step 504 and step 505 simultaneously.

After the application layer of the UE generates the time information, the application layer of the UE will perform step 506.

In step 506, the application layer of the UE transmits time information to the access layer of the UE.

Step 507, the application layer of the UE sends an application layer measurement report to the access layer of the UE.

It should be understood that there is no explicit chronological restriction between step 506 and step 507. That is, the application layer of the UE may perform step 506 before step 507, may perform step 507 before step 506, and may perform step 506 and step 507 at the same time. The details are not limited herein. However, step 506 should be located after step 505 and step 507 should be located after step 504.

In step 508, the access stratum of the ue determines whether to wait for the next application layer measurement report according to the time information.

When the access stratum of the UE determines that it is not necessary to wait for the next application layer measurement report, it encapsulates the received multiple application layer measurement reports into message 1, i.e. triggers to perform step 509. When the access stratum of the UE determines that it needs to wait for the next application layer measurement report, then the UE will continue to receive the next application layer measurement report from the UE's application layer.

In step 509, the access stratum of the ue encapsulates the received multiple application layer measurement reports into message 1.

In step 510, the access stratum of the ue sends a message 1 encapsulating a plurality of application layer measurement reports to the RAN.

In step 511, the ran sends a message 1 encapsulating a plurality of application layer measurement reports to the TCE.

In this embodiment, steps 507 to 511 are similar to steps 405 to 409, and please refer to the related descriptions in steps 405 to 409, which is not described herein again.

In this embodiment, the access layer of the UE can forward the application layer measurement configuration and the service type from the RAN side to the application layer of the UE, so that the application layer of the UE performs application layer measurement and generates time information. The access stratum of the UE then receives the application layer measurement reports and the time information from the application layer of the UE, and the access stratum of the UE is further capable of deciding, based on the time information generated by the application layer of the UE, when to encapsulate one or more application layer measurement reports. Therefore, the flexibility of reporting the application layer measurement report to the RAN by the UE is improved. Further, when the UE determines to encapsulate multiple application layer measurement reports into the message 1 and sends the message 1 to the RAN, the scheme can save signaling used for transmitting the application layer measurement reports between the UE and the RAN and improve the utilization rate of the signaling used for transmitting the application layer measurement reports.

It should be noted that when the time information is determined by the UE, it may be that the application layer of the UE determines the time information and then sends the time information to the access layer of the UE, for example, the foregoing steps 505 and 506; it may also be that the access stratum of the UE determines the time information, and in this case, step 505 and step 506 in the foregoing embodiment may be replaced with step 505a.

It should be understood that there is no explicit chronological restriction between step 505a and step 507. That is, the application layer of the UE may perform step 505a first and then step 507, may perform step 507 first and then step 505a, and may perform step 505a and step 507 at the same time. The details are not limited herein. However, step 505a should be located after step 502 and before step 508, and step 507 should be located after step 504.

In step 505a, the access stratum of the UE generates time information.

In one possible embodiment, the access stratum of the UE includes time information in the application layer measurement configuration received from the RAN. For example, the application layer measurement configuration received by the access layer of the UE includes some parameters (e.g., measurement period) related to time or period, and the access layer of the UE determines the parameters (e.g., measurement period) as time information.

In another possible embodiment, the access stratum of the UE generates time information according to some received (or existing) parameters (e.g., measurement period) related to time or period. For example, the access layer of the UE generates a package period for packaging the application layer measurement report according to the measurement period, where the package period is time information generated by the UE.

Further, in a possible embodiment, the access stratum of the UE obtains at least one measurement period from the application layer measurement configuration, or obtains at least one measurement period from other configuration information. Wherein, each measurement period is used to instruct the UE to obtain a time interval of two adjacent application layer measurement reports corresponding to the same service type. Optionally, each measurement period in the at least one measurement period corresponds to one service type, and the service types corresponding to each measurement period are not completely the same. Then, the access stratum of the UE may calculate an encapsulation period (e.g., a second encapsulation period, a third encapsulation period, etc.) indicating a period for encapsulating at least one application layer measurement report into one message using the aforementioned measurement period. The time information determined by the access stratum of the UE includes the encapsulation period.

In another possible embodiment, the time information is an encapsulation amount determined by the access stratum of the UE, and the access stratum of the UE determines the encapsulation amount according to some time or period related parameters, which may be understood as the number of application layer measurement reports encapsulated in one first message. For example, the access stratum of the UE may set a counting device (e.g., a counter) according to the aforementioned number of encapsulations, and after the access stratum of the UE starts the aforementioned counting device, the access stratum of the UE counts once every time it receives an application layer measurement report from the application layer of the UE until the number of application layer measurement reports received by the access stratum of the UE reaches the aforementioned number of encapsulations. Then, the access stratum of the UE encapsulates the obtained multiple application layer measurement reports (i.e. the number of application layer measurement reports indicated by the aforementioned encapsulated quantity) into the aforementioned message 1.

In another possible embodiment, the time information is an encapsulation size determined by an access stratum of the UE, and the access stratum of the UE determines the encapsulation size according to some time or period related parameters, and the encapsulation size is used for indicating a total size of an application layer measurement report triggering encapsulation of one message. For example, if the encapsulation size is 2M, when the size of the application layer measurement report obtained by the access stratum of the UE is greater than or equal to 2M, the access stratum of the UE encapsulates the obtained application layer measurement report into a message 1.

In one possible implementation, the access stratum of the UE determines the time information according to a start indication corresponding to each service type. For example, the access stratum of the UE determines the time information according to the time of the start instruction corresponding to each service type. For example, the access layer of the UE obtains the deviation of the time of the start indication corresponding to each service type, and if the deviation of the time of the start indication corresponding to two service types is within a certain range, the access layer of the UE may wait for the application layer measurement report corresponding to another service type when the terminal device obtains the application layer measurement report corresponding to the first service type. Otherwise, the access layer of the UE does not need to wait for the measurement result of the application layer corresponding to another service type, i.e. the terminal device may generate a message.

In this embodiment, the access layer of the UE can forward the application layer measurement configuration and the service type from the RAN side to the application layer of the UE, and the access layer of the UE can also generate time information. The access stratum of the UE then receives application layer measurement reports from the application layer of the UE, and decides, based on time information generated by the access stratum of the UE, when to encapsulate one or more application layer measurement reports. Therefore, the flexibility of reporting the application layer measurement report to the RAN by the UE is improved. Further, the UE determines to encapsulate multiple application layer measurement reports into the message 1, and sends the message 1 to the RAN, so that signaling used for transmitting the application layer measurement reports between the UE and the RAN can be saved, and the utilization rate of the signaling used for transmitting the application layer measurement reports is improved.

In addition, as shown in fig. 6, the present application further provides a measurement report transmission method, which involves a first access network device and a second access network device. The first access network device and the second access network device may be access network devices adjacent to each other, or data exchange may be performed between the first access network device and the second access network device, or the first access network device and the second access network device may provide a Dual Connectivity (DC) service for the terminal device.

Step 601, the first access network device obtains an application layer measurement index that can be recognized by the first access network device.

The application layer measurement index that can be recognized by the first access network device may also be understood as an application layer measurement report (RAN-visible QoE report) that can be recognized by the first access network device, where the application layer measurement index that can be recognized by the first access network device is a measurement index of an application layer in the application layer measurement report that can be recognized and used by the first access network device.

Optionally, the application layer measurement indicator includes a measurement value of the application layer measurement indicator and/or an evaluation value of the application layer measurement indicator. Wherein the measurement value of the application layer measurement indicator is a result that the RAN can recognize about the measurement of the application layer indicator. The evaluation value of the application layer measurement index is a comprehensive score of an application layer index recognizable by the RAN, or a comprehensive score of an access layer index, or a comprehensive score obtained by combining the application layer index and the access layer index, or a value indicating the degree of superiority and inferiority of the application layer index (for example, the value may be good, medium, or poor).

In one possible embodiment, the first access network device receives an application layer measurement indicator from the terminal device, which is recognizable by the first access network device. In this embodiment, the terminal device may obtain the application layer measurement indicator recognizable by the first access network device by using the methods provided in the embodiments corresponding to fig. 2, fig. 4, and fig. 5.

In another possible implementation, the first access network device generates an application layer measurement indicator that is recognizable by the first access network device according to an application layer measurement report that is received from the terminal device and is not recognizable by the first access network device.

Illustratively, the application layer measurement report unrecognizable by the first access network device is a QoE measurement report container (QoE measurement report container), information capable of reflecting the application layer measurement index is encapsulated in the container, and the first access network device decapsulates the container to obtain the information capable of reflecting the application layer measurement index. Then, the first access network device screens out the application layer measurement indexes recognizable by the first access network device from the information capable of reflecting the application layer measurement indexes.

In this embodiment, the terminal device may obtain the application layer measurement indicator that is not recognizable by the first access network device by using the methods provided in the embodiments corresponding to fig. 2, fig. 4, and fig. 5.

Step 602, a first access network device obtains an access stratum measurement indicator.

The access stratum measurement index is used for describing the performance of at least one cell of the access network equipment for providing service for the terminal equipment. The measured value of the access stratum measurement index can reflect whether a certain cell can provide a certain service for the terminal equipment or not and the quality degree of the capability of providing the service.

Illustratively, the access stratum measurement metrics include: indices reflecting wireless signal quality (e.g., reference Signal Received Power (RSRP), reference signal received quality (RSRP), and signal to interference noise ratio (SINR), etc.), bit error rate, block error rate, delay, throughput, and radio load.

Step 603, the first access network device generates a first corresponding relationship, where the first corresponding relationship includes a corresponding relationship between an access stratum measurement indicator and an application stratum measurement indicator.

In this embodiment, after the first access network device receives the access layer measurement indicator and the application layer measurement indicator, the first access network device generates a first corresponding relationship according to the access layer measurement indicator and the application layer measurement indicator.

In an optional implementation manner, the first access network device generates the first corresponding relationship according to the application layer measurement index that the first access network device can recognize and reported from each terminal device under the first access network device and the access layer measurement index corresponding to the application layer measurement index that the first access network device can recognize. The access layer measurement index corresponding to the application layer measurement index recognizable by the first access network device is an access layer measurement index associated with the application layer measurement index recognizable by the first access network device and reported by the terminal device. For example, assuming that an application layer measurement of a certain service is performed within a certain time period to obtain an application layer measurement index 1, the access layer measurement index associated with the application layer measurement index 1 refers to: the access layer measurement index in the time period, or the access layer measurement index when the terminal device reports the application layer measurement index, or the access layer measurement index when the access network device receives the application layer measurement index. Optionally, the first access network device generates the first corresponding relationship by integrating the application layer measurement indexes of the plurality of terminal devices and the associated access layer measurement indexes. For example, the application layer indexes corresponding to the access layer measurement indexes in a certain range may be integrated to obtain a value of the integrated application layer index (e.g., an average value, a minimum value, a maximum value, or a weighted average value) or a value range of the integrated application layer index value (e.g., an average value range, a minimum value range, or a maximum value range).

In an optional embodiment, the first access network device stores the access stratum measurement indicator and the application stratum measurement indicator in association. For example, the access stratum measurement index and the application layer measurement are correspondingly stored in a table.

For example, when the application layer measurement indicator is a measurement value of the application layer measurement indicator, the first corresponding relationship may be as shown in table 1-1 below:

TABLE 1-1

For example, in the examples listed in the foregoing tables 1-1, the measurement value of the access stratum measurement indicator represents a measurement value of RSRP, and the measurement value of the application stratum measurement indicator represents average throughput. In this case, table 1-1 represents the range corresponding to the measurement value to which the measurement index is applied in the range corresponding to the measurement value of the access stratum measurement index in each cell. Optionally, the first corresponding relationship is a corresponding relationship between a plurality of access stratum measurement indexes and an application stratum measurement index. For example, the first mapping relationship is that the measurement value corresponding to the application layer measurement indicator #1 is the measurement value #3 when the measurement value of the access layer measurement indicator #1 is the measurement value #1 and the measurement value of the access layer measurement indicator #2 is the measurement value #2 in the cell 1.

Step 604, the first access network device sends the first mapping relationship to the second access network device.

In an alternative embodiment, the first correspondence is implemented in the form of a table (e.g., the aforementioned table 1-1). At this time, the first access network device sends the table in which the first correspondence relationship is stored to the second access network device.

In another optional implementation manner, the first access network device encapsulates the access stratum measurement indicator and the application layer measurement indicator that need to correspond to each other into one message, and sends the message to the second access network device, so that the second access network device can know that the access stratum measurement indicator and the application layer measurement indicator in the message have a corresponding relationship.

Illustratively, the first access network device encapsulates the cell identifier of the cell 1, the measurement value of the access stratum measurement indicator corresponding to the cell 1, and the measurement value of the application stratum measurement indicator corresponding to the cell 1 into the message 001. Then, the first access network device sends the message 001 to the second access network device, so that after the second access network device receives the message 001, it can be known that the measurement value of the access stratum measurement indicator and the measurement value of the application layer measurement indicator in the message 001 both correspond to the cell 1.

After the second access network device receives the first corresponding relationship, the second access network device may obtain, according to the first corresponding relationship, a quality degree of a service provided by a certain cell of the first access network device for the terminal device based on the first corresponding relationship. Further, the second access network device may determine whether to switch the terminal device located in a certain cell of the second access network device to a certain cell under the first access network device based on the first corresponding relationship. For example, when the second access network device determines whether to switch the terminal device located in the service range of the second access network device to the cell in the first access network device, the second access network device may obtain, according to the wireless signal quality of each cell in the first access network device at present and the first corresponding relationship, a value of an application layer index (referred to as a value of the application layer index after switching) corresponding to the terminal device after being switched to each cell in the first access network device. Therefore, the second access network device can judge whether to switch the terminal device to the cell in the first access network device (for example, when the values of the application layer indexes of the terminal device after switching in each cell in the base station are all lower than a threshold, the second access network device determines not to switch the terminal device to the cell in the first access network device, otherwise, the second access network device determines to switch the terminal device to the cell in the first access network device). Further, when the second access network device determines to switch the terminal device to the first access network device, the second access network device may further determine which cell to switch to in the first access network device (for example, which cell with the largest value of the switched application layer index is selected).

It should be noted that, in the present application, the handover includes the terminal device handing over from one access network device to another access network device, and also includes the access network device migrating some data to another access network device (for example, one access network device requests another access network device to provide the dual connectivity service).

Step 605, the first access network device sends a handover request to the second access network device, where the handover request carries values of expected application indexes of each service of the terminal device.

Step 605 is an optional step.

The value of the expected application layer index of each service may be sent to the first access network device by the core network, or may be calculated by the first access network device according to the QoS requirements of each service of the terminal device, or may be an application layer measurement index that is obtained by the first access network device from the terminal device and is recognizable by the first access network device.

The second access network device may determine whether to admit the terminal device and which services to admit according to a value of an expected application layer index of each service of the terminal device. For example, if the second access network device cannot meet the value of the expected application index of each service of the terminal device, the second access network device may refuse to admit the terminal device. When the second access network device cannot meet the value of the expected application index of the service 1 of the terminal device, the second access network device may refuse to accept the service 1 of the terminal device.

In this embodiment, the first access network device and the second access network device may interactively reflect a correspondence between a measurement result of an access stratum quality status (that is, a measurement value of an access stratum measurement index) and a measurement value of an application layer measurement index. Therefore, it is advantageous for the second access network device to determine whether to handover the terminal device in a certain cell of the second access network device to a certain cell of the first access network device based on the aforementioned correspondence. Therefore, decision basis can be provided for the access network equipment to switch the terminal equipment, and the service performance of the terminal equipment is better ensured. In addition, the first access network device sends the value of the expected application index of each service of the terminal device to the second access network device, so that the second access network device judges whether to accept the terminal device according to the value of the expected application index of the terminal device.

In addition, as shown in fig. 7, the present application also provides a measurement report transmission method involving a first access network device and a second access network device. The first access network device and the second access network device may be adjacent access network devices, or data exchange may be performed between the first access network device and the second access network device, or the first access network device and the second access network device may provide a Dual Connectivity (DC) service for the terminal device.

Step 701, a first access network device obtains an application layer measurement index that can be recognized by the first access network device.

The application layer measurement index comprises a measurement value of the application layer measurement index and/or an evaluation value of the application layer measurement index;

step 701 is similar to step 601, and please refer to the related description in step 601, which is not described herein again.

In step 702, the first access network device obtains wireless configuration information.

Wherein, the radio configuration information is used to indicate at least one cell of the access network device to configure the radio configuration for the terminal device. Wherein the radio configuration includes Carrier Aggregation (CA) and/or Dual Connectivity (DC). Therefore, the foregoing radio configuration information may also be understood as being capable of indicating whether a certain cell under the first access network device configures a carrier aggregation CA for the terminal device, and whether the cell configures a dual connectivity DC for the terminal device.

Step 703, the first access network device generates a second corresponding relationship, where the second corresponding relationship includes a corresponding relationship between the radio configuration information and the application layer measurement indicator.

In this embodiment, after the first access network device obtains the wireless configuration information and the application layer measurement indicator, the first access network device generates a second mapping relationship according to the wireless configuration information and the application layer measurement indicator.

In an optional implementation manner, the first access network device generates the second corresponding relationship according to application layer measurement indexes recognizable by the first access network device and reported from each terminal device under the first access network device, and the wireless configuration information configured by the first access network device for each terminal device. The wireless configuration information configured by the first access network device for each terminal device is wireless configuration information associated with an application layer measurement index that can be identified by the first access network device and reported by the terminal device. For example, assuming that an application layer measurement of a certain service is performed within a certain time period to obtain an application layer measurement index 1, the radio configuration information associated with the application layer measurement index 1 refers to: the wireless configuration information in the time period, or the wireless configuration information when the terminal device reports the application layer measurement index, or the wireless configuration information configured for the terminal device when the access network device receives the application layer measurement index. Optionally, the first access network device generates the second corresponding relationship by integrating the application layer measurement indicators of the plurality of terminal devices and the associated radio configuration information. For example, the values of the application layer indexes of each terminal device under the same wireless configuration information may be integrated to obtain the value of the integrated application layer index (for example, an average value, a minimum value, a maximum value, or a weighted average, or a range of the values of the application layer indexes).

In an optional embodiment, the first access network device stores the radio configuration information and the application layer measurement indicator in association with each other. For example, the radio configuration information and the application layer measurement correspondence are stored in a table.

For example, the second correspondence relationship may be as shown in the following table 2-1:

TABLE 2-1

For example, in the example listed in the aforementioned table 2-1, the measurement value of the application layer measurement index indicates average throughput, and the radio configuration information indicates whether CA and/or DC are supported. In this case, table 2-1 shows the ranges to which the measurement values of the measurement indexes are applied in each cell when the values corresponding to the radio configuration information are taken.

Step 704, the first access network device sends the second corresponding relationship to the second access network device.

In an alternative embodiment, the second correspondence is implemented in the form of a table (e.g., the aforementioned table 2-1). At this time, the first access network device sends the table in which the second correspondence is stored to the second access network device.

In another optional implementation manner, the first access network device encapsulates the radio configuration information and the application layer measurement indicator that need to correspond to one message and sends the message to the second access network device, so that the second access network device can know that the radio configuration information and the application layer measurement indicator in the message have a corresponding relationship.

Illustratively, the first access network device encapsulates the cell identifier of the cell 2, the radio configuration information (e.g., supporting carrier aggregation CA) corresponding to the cell 2, and the measurement value of the application layer measurement indicator corresponding to the cell 2 into the message 002. Then, the first access network device sends the message 002 to the second access network device, so that after the second access network device receives the message 002, it can be known that both the wireless configuration information and the measurement value of the application layer measurement index in the message 002 correspond to the cell 2, that is, the second access network device can know that the cell 2 supports configuring the carrier aggregation CA for the terminal device and that the terminal device is at the level of the application layer measurement index in the cell 2 when the cell 2 configures the carrier aggregation CA for the terminal device.

After the second access network device receives the second corresponding relationship, the second access network device may obtain the wireless configuration condition of a certain cell under the first access network device based on the second corresponding relationship according to the second corresponding relationship. Further, the second access network device may determine whether to switch the terminal device located in a certain cell of the second access network device to a certain cell under the first access network device based on the second correspondence. For example, the terminal device 1 in the second access network device supports carrier aggregation CA, and the measurement value of the application layer measurement indicator in the cell 2 supporting the configuration of carrier aggregation CA for the terminal device under the first access network device does not meet the handover condition of the terminal device 1, the second access network device will not handover the terminal device 1 to the cell 2 supporting carrier aggregation CA.

Step 705, the first access network device sends a handover request to the second access network device, where the handover request carries values of expected application indexes of each service of the terminal device.

Step 705 is an optional step.

In this embodiment, the first access network device and the second access network device may interactively reflect a correspondence between the radio configuration capability of the cell and a measurement value of the application layer measurement index. Therefore, it is advantageous for the second access network device to determine whether to handover the terminal device in a certain cell of the second access network device to a certain cell of the first access network device based on the aforementioned correspondence. Therefore, decision basis can be provided for the access network equipment to switch the terminal equipment, and the service performance of the terminal equipment is better ensured.

It should be noted that the aforementioned embodiments corresponding to fig. 6 and fig. 7 may be combined. That is, in a possible implementation, the first access network device generates not only the first corresponding relationship but also the second corresponding relationship, and the first access network device can send both the first corresponding relationship and the second corresponding relationship to the second access network device. Then, the second access network device can decide whether to switch a certain terminal device under the second access network device to a certain cell under the first access network device according to the first corresponding relationship and the second corresponding relationship. It should also be noted that the first access network device may send the aforementioned first and second correspondences together to the second access network device in one message. Of course, the first access network device may also send the first corresponding relationship and the second corresponding relationship to the second access network device by using two messages. In one possible implementation, the first access network device performs a third corresponding relationship, where the third corresponding relationship is a relationship between a measurement value of an access stratum measurement indicator, radio configuration information, and a measurement value of an application layer measurement indicator. For example, the third mapping relationship is that the measurement value of the access stratum measurement indicator #1 in the cell 1 is the measurement value #1 and the measurement value of the application stratum measurement indicator #1 corresponding to the radio configuration information in the configuration #1 is the measurement value #3.

As shown in fig. 8, a schematic structural diagram of a communication device 80 according to this embodiment is provided. It should be understood that the terminal device in the method embodiment corresponding to fig. 2 and the UE in the method embodiments corresponding to fig. 4 and 5 may be based on the structure of the communication apparatus 80 shown in fig. 8 in this embodiment.

The communication device 80 includes at least one processor 801, at least one memory 802, and at least one transceiver 803. Wherein the processor 801, the memory 802 and the transceiver 803 are connected.

Optionally, the memory 802 may be integrated with the processor 801, for example, within one or more chips. The memory 802 can store program codes for executing the technical solutions of the embodiments of the present application, and the processor 801 controls the execution of the program codes, and various executed computer program codes can also be regarded as drivers of the processor 801. It should be understood that fig. 8 in this embodiment only shows one memory and one processor, but in practical applications, multiple processors or multiple memories may exist in the communication device 80, and the details are not limited herein. The memory 802 may also be referred to as a storage medium, a storage device, or the like. The memory 802 may be a memory element on the same chip as the processor (i.e., an on-chip memory element), or a separate memory element, which is not limited in this embodiment.

In this embodiment, the transceiver 803 may be used to support the reception or transmission of radio frequency signals between the communication apparatus 80 and the access network device, and the transceiver 803 may be connected to the antenna 804. The transceiver 803 includes a transmitter Tx and a receiver Rx. In particular, one or more antennas 804 may receive a radio frequency signal, and the receiver Rx of the transceiver 803 is configured to receive the radio frequency signal from the antenna 804, convert the radio frequency signal into a digital baseband signal or a digital intermediate frequency signal, and provide the digital baseband signal or the digital intermediate frequency signal to the processor 801, so that the processor 801 performs further processing on the digital baseband signal or the digital intermediate frequency signal, such as demodulation processing and decoding processing. In addition, the transmitter Tx in the transceiver 803 is also used to receive a modulated digital baseband signal or digital intermediate frequency signal from the processor 801, convert the modulated digital baseband signal or digital intermediate frequency signal into a radio frequency signal, and transmit the radio frequency signal through the one or more antennas 804. Specifically, the receiver Rx may selectively perform one or more stages of down-mixing and analog-to-digital conversion on the rf signal to obtain a digital baseband signal or a digital intermediate frequency signal, and the sequence of the down-mixing and analog-to-digital conversion is adjustable. The transmitter Tx may selectively perform one or more stages of up-mixing and digital-to-analog conversion processes on the modulated digital baseband signal or the modulated digital intermediate frequency signal to obtain the rf signal, where the order of the up-mixing and the digital-to-analog conversion processes is adjustable. The digital baseband signal and the digital intermediate frequency signal may be collectively referred to as a digital signal.

It should be understood that the aforementioned transceiver 803 may also be referred to as a transceiving unit, a transceiver, a transceiving means, etc. Optionally, a device for implementing a receiving function in the transceiver unit may be regarded as a receiving unit, and a device for implementing a sending function in the transceiver unit may be regarded as a sending unit, that is, the transceiver unit includes a receiving unit and a sending unit, the receiving unit may also be referred to as a receiver, an input port, a receiving circuit, and the like, and the sending unit may be referred to as a transmitter, a sending circuit, and the like.

The processor 801 may be a baseband processor or a Central Processing Unit (CPU), and the baseband processor and the CPU may be integrated together or separated. The processor 801 may be configured to implement various functions for the terminal device, such as processing communication protocols and communication data, or controlling the whole terminal device, executing software programs, and processing data of the software programs; or to assist in completing computational processing tasks, such as processing of graphical images or audio, etc.; or the processor 801 may be configured to perform one or more of the functions described above.

In addition, the output device 806 is in communication with the processor 801 and may display information in a variety of ways, which are not limited thereto.

Specifically, in the communication apparatus 80, the transceiver 803 can acquire time information, wherein the time information indicates a timing for encapsulating an application layer measurement report, which is a measurement result obtained by the terminal device performing application layer measurement. The processor 801 can encapsulate at least one application layer measurement report into the first message according to the time information. The transceiver 803 can also be capable of transmitting the first message to an access network device under the control of the processor 801.
