Description

Application layer measuring method and related device

Technical Field

The embodiment of the application relates to the field of communication, in particular to an application layer measuring method and a related device.

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, i.e., defined from the comfort of the service application. Measuring the quality of experience is called QoE measurement (also called application layer measurement). The application layer measurement may also refer to the quality and performance of the reporting device, application or service of the terminal device. The operator can obtain the user experience status by collecting the QoE measurement results (also called application layer measurement results), and then better optimize the network to improve the user experience.

When the load of the access network equipment is higher, the access network equipment can inform the terminal equipment and suspend the reporting of the QoE measurement result. At this point, the terminal device may not stop QoE measurement and continue to save the newly generated QoE measurement result. The current QoE measurement result storage scheme has lower efficiency.

Detailed Description

The following describes embodiments of the present invention in detail with reference to the accompanying drawings. The network architecture and the service scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of a new service scenario.

Fig. 1 shows a schematic diagram of a possible system network of the present application. As shown in fig. 1, at least one terminal 10 communicates with a Radio Access Network (RAN). The RAN includes at least two base stations: base station 20 and base station 30, only two base stations and one user equipment UE are shown in the figure. The RAN is connected to a Core Network (CN). The core network includes one or more core network devices. Optionally, the CN may be coupled to one or more External networks (External networks), such as the Internet, public Switched Telephone Network (PSTN), etc. In the moving process, the connection between the UE and the radio access network may be switched from the base station 20 to the base station 30, in this case, the base station 20 may be referred to as a source base station, the base station 30 may be referred to as a target base station, and the UE may communicate with the base station through an air interface (e.g., uu interface).

In Long Term Evolution (LTE) and New Radio (NR), UEs and base station/access and mobility management function (AMF) entities communicate over the air. To better process data, network protocols define several protocol stacks, each of which functions differently, for example, as shown in fig. 2. The specific process may be that the UE sends an NAS message to the base station, the base station transparently transmits the NAS message to the AMF, and the base station does not parse the NAS message in the process of transparent transmission. The NAS layer is mainly responsible for management functions such AS Public Land Mobile Network (PLMN) selection, manual selection, access control, registration, subscription information, etc., and specific procedures may be performed in cooperation with other protocol layers, such AS an Access Stratum (AS) layer.

The AS layer refers to a protocol layer except the NAS layer, and may include Radio Resource Control (RRC), packet Data Convergence Protocol (PDCP), radio Link Control (RLC), medium Access Control (MAC), and physical layer (PHY), where the AS layer is mainly responsible for functions such AS switching, encryption, data retransmission, sequencing, and transmission.

The communication device described in this application refers to a network element in a communication system, such as a terminal, a base station, and a core network device.

A terminal may also be called a User Equipment (UE). A UE is a terminal device with communication capabilities, also referred to as a terminal, and may include a handheld device with wireless communication capabilities, a vehicle mounted device, a wearable device, a computing device or other processing device connected to a wireless modem, etc. Such as a handheld device, a vehicle-mounted device, etc., having a wireless connection function.

In future communication systems, such as 6G, the above network element may also have other names, which is not limited in this application.

In order to facilitate understanding of the embodiments of the present application, the following description will first exemplify a main flow of application layer measurement.

For some streaming services or voice services, such as streaming services (streaming services), voice services, multimedia telephony services for IP multimedia systems (MTSI), virtual Reality (VR) services, augmented Reality (AR) services, multicast and Broadcast Services (MBS), etc., pure signal quality does not reflect user experience of users when using these services, and operators want to know how the user experience is, so as to better optimize networks to improve user experience. Such measurement collections are referred to as QoE measurement collections, and may also be referred to as application layer measurement collections.

The base station receives configuration information related to these measurements from the CN or OAM or EM. Some of the configuration information may be sent to the base station in a transparent container (container), and the base station sends the configuration to the UE through an RRC message. The RRC layer of the UE receives the application layer measurement results from an upper layer (e.g., application layer), and then transmits the measurement results to the base station. The measurement results may be provided to the base station in the form of a package of transparent containers. The information received by the base station from the CN or OAM or EM may include other information of QOE measurement, such as an area range of QOE measurement, a service type of QOE measurement, etc., in addition to the above configuration information of measurement. The base station may send the QoE measurement configuration to the UE through an RRC reconfiguration message. The base station may configure one signaling bearer for the UE to transmit the QoE measurement results. The measurement results of the UE may be transmitted through the signaling bearer. The base station that issues the configuration information related to the QoE measurement to the UE may not be the same base station as the base station that receives the QoE measurement result sent by the UE.

Referring to fig. 3, the main flow of qoe measurement is as follows:

in step 301, the ran acquires QoE measurement configuration information from the CN or OAM.

For signaling-based QoE measurement, the RAN acquires QoE measurement configuration information from the CN.

The QOE measurement configuration information includes a QOE measurement configuration container (QOE measurement configuration container), a service type (service type), and the like. In addition, the QOE measurement configuration information further includes a region scope of QOE Measurement Collection (QMC). The region range of QMC 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. Carried in the QoE measurement configuration container is the QoE measurement configuration for the UE. For example, the QoE measurement configuration container includes information indicating which measurement values are reported by the UE, and reporting interval. The reporting interval refers to that the terminal device reports the measurement result periodically or reports the measurement result after the service is finished. The QoE measurement configuration container may also include the start time and duration of the measurement, as well as the area range of the measurement. The QoE measurement configuration container may be in the form of Extensible Markup Language (XML) to carry the above information. Since the access network device does not unpack the container after obtaining the container encapsulating the QoE measurement configuration, such QoE measurement configuration that the access network device does not actively unpack the identification is referred to as QoE measurement configuration that the access network device cannot identify. In addition, the QoE measurement result corresponding to the QoE measurement configuration unrecognizable by the access network device is also a QoE measurement result unrecognizable by the access network device, and the QoE measurement result unrecognizable by the access network device is also transmitted to the access network device by being encapsulated in a container, so the QoE measurement result unrecognizable by the access network device is often referred to as a QoE measurement report container (QoE measurement report container).

The CN informs of the QOE measurement configuration information for a particular UE, such as sending the QOE measurement configuration information over an interface message between the RAN and the CN for a particular UE.

For management-based QoE measurement, the RAN acquires QoE measurement configuration information from OAM or EM. OAM or EM informs not QOE measurement configuration information for a certain UE.

In addition, the CN or OAM may also notify the base station, and the application layer measurement configuration sent to the UE includes an indication for the UE to report the following application layer indicators (the base station may sense or may recognize that the UE will measure the following application layer indicators), where the application layer indicators may be the following indicators:

average throughput: the indicator indicates the total number of bits received by the application layer of the UE during a measurement interval. Such as for streaming media services. Initial play time delay: the indicator indicates the initial playback delay at which the streaming media starts to be presented. Such as specifically defined from the time the first piece of media is retrieved to the time the streaming media is extracted from the client buffer. For example, reference may be made to the definition in the 3GPP protocol TS 26.247-g 30.

Buffer level: the indicator indicates the duration of time the media data can be played back, starting from the current play moment. And (3) playing time delay: the indicator indicates the playback delay of the streaming media start. Such as may be specifically defined as the time delay from receiving a play/rewind/start trigger to playing media from a Dynamic Adaptive Streaming over HTTP (DASH) player transported by the hypertext transfer protocol. For example, reference may be made to the definition in the 3GPP protocol TS 26.247-g 30.

Duration of deterioration: the indicator indicates the interval between the Nepal Time (NPT) corresponding to the last good quality frame before degradation and the Nepal Time corresponding to the first subsequent good quality frame. A good quality frame refers to a frame that is completely accepted and all parts of the picture corresponding to the frame contain correct content, or a new frame (i.e. not dependent on any previously decoded frame) or only dependent on a previously decoded good quality frame. Number of consecutive lost packets: the indicator indicates the number of Real-time Transport Protocol (RTP) messages that are continuously lost. For example, reference may be made to the definition in the 3GPP protocol TS 26.114-g 20.

Jitter duration: jitter is the difference between the actual playing time and the desired playing time of a frame exceeding a threshold. The desired play-out time of a frame is the play-out time of the last play-out frame plus (the difference between the nepal time of the current frame and the nepal time of the last play-out frame). Duration of step loss: out-of-sync is when the absolute time difference between a value a and a value B exceeds a certain threshold. The value a here refers to the difference between the playing time of the last playing frame of a video stream and the playing time of the last playing frame of a voice stream. The value B here refers to the difference between the expected playing time of the last playing frame of the video stream and the expected playing time of the last playing frame of the speech stream. For example, reference may be made to the definition in the 3GPP protocol TS 26.114-g 20.

Round-trip delay: the indicator indicates the round trip time at RTP level plus an additional two-way delay in the client due to buffering and other processing (RTP level- > speaker- > microphone- > RTP level). Average code rate-the indicator indicates the bit rate at which valid media information is encoded during the measurement period. For example, reference may be made to the definition in the 3GPP protocol TS 26.114-g 20.

Analog quality perspective switching delay (configurable quality perspective switching latency): the index reports the time delay and quality related factors when the view angle moves to cause quality degradation. The quality-related factors include quality ranking value (quality ranking value), resolution. Stuck condition: the indicator indicates whether a pause has occurred during the playing of the video stream, or the length of time that the pause has occurred. For example, reference may be made to the definition in the 3GPP protocol TS 26.118-g 02.

In this application, sensing means that the access network device can interpret the received information, and "sensing" may be replaced by visible, learned, detected, and the like, without limitation.

In step 302, the ran sends the application layer measurement configuration to the UE.

For signaling-based QoE measurement, the RAN sends application layer measurement configuration to the corresponding UE. The application layer measurement configuration includes the foregoing QoE measurement configuration container.

For the management-based QoE measurement, the RAN selects an appropriate UE for QoE measurement according to QoE measurement configuration information sent by OAM/EM, whether the UE supports the corresponding QoE measurement, and other factors. After the RAN has selected the UE, it sends the application layer measurement configuration to UE. where the application layer measurement configuration includes the previous QoE measurement configuration container.

The RAN sends the application layer measurement configuration acquired from the CN or the OAM or the EM to the UE through RRC message, and the message also carries the service type corresponding to the application layer measurement configuration.

Note: it is also mentioned in the prior art that the RAN can trigger the configuration of the application layer measurement configuration for the UE by itself, and is not limited to trigger the UE by receiving the command in step 1.

Besides sending the application layer measurement configuration to the UE, the RAN may also send some configuration information to the UE indicating the UE to report the QoE measurement result perceived by the RAN. The configuration information corresponding to the QoE measurement result reported by the UE is indicated to the RAN to notify the UE of reporting some application layer indexes in a form (for example, in an information element form) that the RAN can perceive, so that the RAN can know the corresponding application layer index measurement result, or the RAN can notify the UE of reporting a comprehensive score of an application layer index 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 an index indicating the degree of goodness of the application layer index (for example, the value may be good, medium, or poor) (for example, the base station issues some threshold values to the UE, and the UE knows the index reporting the degree of goodness corresponding to the application layer index measurement result according to the application layer index measurement result and some threshold values corresponding to the application layer index measurement index). In addition, the RAN may not need to issue some configuration information about the RAN sensing measurement result to the UE, and after the UE obtains the application layer index, the UE reports some application layer indexes that are specified by the protocol and that can be obtained by the current UE, or a comprehensive score of one application layer index, 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 an index indicating the degree of goodness and badness of the application layer to the RAN.

Optionally, the application layer measurement configuration may also not include the foregoing QoE measurement configuration container, for example, including a service type corresponding to the application layer measurement configuration, and indicating the UE to report configuration information corresponding to the QoE measurement result perceived by the RAN.

The RAN configures a bearer for the UE to transmit QoE measurement results, where the bearer may be a signaling radio bearer, such AS srb4, and the configuration information of the bearer may be configured in the same RRC message AS the application layer measurement configuration and sent to the AS of the UE (such AS the RRC layer of the UE), or may be sent through different messages.

In step 303, the AS of the UE transmits the application layer measurement configuration received from the RAN to an upper layer of the AS of the UE.

The upper layer of the AS of the UE may be an application layer, or may be another layer that can perform QoE measurement.

The AS of the UE sends the application layer measurement configuration and the service type to an upper layer of the AS of the UE.

And the upper layer of the AS of the UE carries out QoE measurement according to the measurement configuration of the application layer.

In addition to sending the application layer measurement configuration to the upper layer of the AS, the AS of the UE also sends some application layer indicator configurations, which are received from the RAN and reported in a form that can be perceived by the RAN, to the upper layer of the AS of the UE.

Step 304, the upper layer of the AS of the UE sends the application layer measurement result to the AS of the UE.

The upper layer of the AS of the UE reports the measurement result of the application layer according to a certain rule (for example, the rule is included in the measurement configuration of the application layer). For example, the upper layer of the AS of the UE reports the measurement result of the application layer periodically. For example, the UE may report the application layer measurement result after a session is ended.

When the upper layer of the AS of the UE needs to report the measurement result of the application layer according to the measurement configuration of the application layer, the upper layer of the AS of the UE sends the measurement result of the application layer to the AS of the UE, and simultaneously, the upper layer of the AS of the UE can indicate the service type corresponding to the QOE measurement result.

In addition, the upper layer of the AS of the UE may report the measurement result visible to the RAN (e.g., an application layer index or a composite score reported in the form of an information element) in addition to the measurement result invisible to the RAN.

Step 305, the AS of the ue sends the application layer measurement result to the RAN.

The AS of the UE sends the application layer measurement result and the corresponding service type to the RAN. Such as carrying the information in uplink RRC messages. The application layer measurements are also sent to the RAN via a contiiner format.

Note: the RAN issuing the application layer measurement configuration information may not be the same base station as the RAN receiving the application layer measurement results (due to mobility, the RAN is replaced), or may be the same base station.

In addition, the AS of the UE may report the measurement result visible to the RAN (e.g., an application layer index or a composite score reported in the form of an information element) in addition to the measurement result invisible to the RAN.

In step 306, the ran sends the application layer measurements to the TCE.

The RAN sends the application layer measurement results to the TCE.

In addition, the RAN may optimize radio resources according to a measurement result that is reported by the UE and visible to the RAN (for example, when a measurement result of an application layer index is not ideal, the base station may allocate more resources to the UE, or increase the scheduling priority of the UE, etc.)

When the RAN load is relatively high, the RAN may notify the UE to suspend QoE measurement result reporting. But the upper layers of the AS of the UE will still continue QoE measurements (also the already started QoE measurements). For the scenario that the upper layer of the AS of the UE still continues QoE measurement, the AS of the UE does not send these results to the RAN, and the UE needs to process the newly generated application layer measurement results.

For steps 307-310, the base station instructs the UE to suspend QoE measurements, and the UE continues to store QoE measurement results. And after receiving a QoE measurement recovery reporting instruction sent by the base station, the UE reports the stored QoE measurement result.

The following takes a 5G network as an example to describe a relevant scheme of the embodiment of the present invention, but the scheme of the present invention is not limited to the 5G network, for example, the scheme of the present invention may also be applied to LTE, a subsequent evolution network, or multiple converged networks, and the like, which is not limited in the embodiment of the present invention. The definitions of the various names given in the different embodiments of the present application may be mutually referenced and are not limited to a certain embodiment.

Example one

The embodiment of the invention provides an application layer measurement result storage scheme based on time indication. As shown in fig. 4, the method comprises the following steps:

401. the RRC layer of the terminal equipment receives the application layer measurement result of the first service type and the application layer measurement result of the second service type from the upper layer of the RRC layer.

Optionally, the first service type and the second service type may also be a first slice (slice) and a second slice, or a first measurement configuration and a second measurement configuration, and the like. That is, the first traffic type and the second traffic type may be replaced by a first slice (slice) and a second slice, or a first measurement configuration and a second measurement configuration in the present invention.

Optionally, before step 401, the terminal device receives the application layer measurement configuration from the access network device and the RRC layer of the terminal device sends the application layer measurement configuration to an upper layer of the RRC layer of the terminal device. See, for example, the description of fig. 3 above.

Optionally, before step 401, the RRC layer of the terminal device may send first capability information to an upper layer of the RRC layer of the terminal device, where the first capability information indicates whether the RRC layer of the terminal device supports the segmented transmission of the application layer measurement result (or whether the RRC layer supports the segmented transmission of the RRC message). The RRC layer of the terminal device supports the segmented transmission of the application layer measurement result, which means that the terminal device can perform the segmented transmission of the RRC message when the application layer measurement result is carried by the RRC message, wherein each segment is also sent by the RRC message. For example, after the RRC layer of the terminal device carries one or more application layer measurement results through an RRC message, and finds that the size of the RRC message exceeds the maximum size of the PDCP SDU supported by the PDCP layer, the RRC layer of the terminal device segments the RRC message into multiple segments, the RRC layer of the terminal device carries the segments through another RRC message (which may be referred to as a new RRC message for short), and the new RRC message carrying each segment carries a segment indication information, where the segment indication information indicates whether the segment is the last segment. And after the upper layer of the RRC layer of the terminal equipment receives the first capability information, acquiring whether the RRC layer of the terminal equipment supports the segmented transmission of the measurement result of the application layer. When the RRC layer of the terminal device supports the segmented transmission of the application layer measurement result, the upper layer of the RRC layer of the terminal device may send a larger application layer measurement result (e.g., an application layer measurement result exceeding the maximum length of PDCP SDUs supported by the PDCP layer) to the RRC layer of the terminal device. After the RRC layer of the terminal device carries the application layer measurement result through the RRC message, if the size of the application layer measurement result exceeds the maximum length of the PDCP SDU supported by the PDCP layer, the RRC layer of the terminal device performs segmented transmission on the RRC message. When the RRC layer of the terminal device does not support the segmented transmission of the application layer measurement result, the upper layer of the RRC layer of the terminal device cannot transmit a larger application layer measurement result (e.g., an application layer measurement result exceeding the maximum length of PDCP SDUs supported by the PDCP layer) to the RRC layer of the terminal device. The first capability indication information may only indicate that the RRC layer of the terminal device supports the segmented transmission of the application layer measurement result, and when the RRC layer of the terminal device does not send the first capability information to an upper layer of the RRC layer of the terminal device, the RRC layer of the default terminal device does not support the segmented transmission of the application layer measurement result. It should be noted that the step of sending the first capability information to the upper layer of the RRC layer of the terminal device by the RRC layer of the terminal device may be independent of this embodiment, that is, may be combined with other embodiments or other technologies.

The upper layer of the RRC layer may be an application layer, or may be other layers that can perform QoE measurement.

402. The RRC layer of the terminal equipment receives first indication information and second indication information from access network equipment, wherein the first indication information indicates that the terminal equipment suspends the reporting of the application layer measurement result of the first service type, and the second indication information indicates that the terminal equipment suspends the reporting of the application layer measurement result of the second service type.

Optionally, the first indication information and the second indication information may be the same information (that is, the access network device instructs the terminal device to stop reporting the application layer measurement results of two or more service types through one indication information), or may be two information (for example, carried through two pieces of signaling).

The application does not limit the precedence relationship between the steps 401 and 402. Before the RRC layer of the terminal device receives the first indication information and the second indication information from the access network device, the RRC layer of the terminal device may not receive the application layer measurement result of the first service type and the application layer measurement result of the second service type.

403. And the RRC layer of the terminal equipment receives first time information from the access network equipment, wherein the first time information indicates the time length for storing the application layer measurement result of the first service type.

404. And the RRC layer of the terminal equipment receives second time information from the access network equipment, wherein the second time information indicates the time length for storing the application layer measurement result of the second service type.

Optionally, the duration indicated by the first time information is different from the duration indicated by the second time information. The network side can indicate the priority of the first service type application layer measurement and the second service type application layer measurement by setting the time length. For example, if the duration indicated by the first time information is set to be longer than the duration indicated by the second time information, it indicates that the first service type application layer measurement priority is higher than the second service type application layer measurement.

Steps 403 and 404 may be performed before steps 401 and 402, for example, when the access network device sends the application layer measurement configuration to the terminal device, the first time information and the second time information are carried by the access network device.

Optionally, the method may further include: 405. the RRC layer of the terminal equipment starts a first timer, the duration of the first timer is determined by the first time information, and when the first timer is overtime, the RRC layer of the UE suspends the storage of the measurement result of the application layer of the first service type; or the RRC layer of the terminal equipment discards the application layer measurement result of the first service type outside the duration.

The duration of the first timer is the duration of saving the application layer measurement result of the first service type indicated by the first time information. When the first timer is overtime, the RRC layer discards an application layer measurement result of the first service type newly received by the RRC layer of the terminal device from an upper layer. Optionally, the RRC layer of the terminal device may start the first timer when receiving the first indication information or receiving the first time information, or start the first timer when the memory space for storing the measurement result of the application layer is used up.

Or, the RRC layer of the terminal device only stores the application layer measurement result of the first service type received in the latest time length, where the time length is the time length indicated by the first time information to store the application layer measurement result of the first service type. For the application layer measurement result of the first traffic type exceeding the time duration, the RRC layer of the terminal device may be discarded. Optionally, when the memory space for storing the application layer measurement result is used up, the RRC layer of the terminal device may instruct to store only the application layer measurement result of the first service type received in the last time.

406. The RRC layer of the terminal equipment starts a second timer, the duration of the second timer is determined by the second time information, and when the second timer is over time, the RRC layer of the UE suspends the storage of the measurement result of the application layer of the second service type; or the RRC layer of the terminal equipment discards the application layer measurement result of the second service type outside the duration.

The duration of the second timer is the duration indicated by the second time information for storing the application layer measurement result of the second service type. And when the second timer is overtime, the RRC layer discards the application layer measurement result of the second service type newly received by the RRC layer of the terminal equipment from the upper layer. Optionally, the RRC layer of the terminal device may start the second timer when receiving the second indication information or receiving the second time information, or start the second timer when the memory space for storing the measurement result of the application layer is used up.

Or, the RRC layer of the terminal device only stores the application layer measurement result of the second service type received in the latest time length, where the time length is the time length indicated by the second time information to store the application layer measurement result of the second service type. For the application layer measurement result of the second traffic type exceeding the duration, the RRC layer of the terminal device may be discarded. Optionally, when the memory space for storing the application layer measurement result is used up, the RRC layer of the terminal device may instruct to store only the application layer measurement result of the second service type received in the last time.

Step 405 generally follows steps 402 and 403, and step 406 generally follows steps 402 and 404. The sequence of other steps is not limited in this application.

By the scheme for storing the measurement result of the application layer, the storage efficiency is improved. In addition, the UE is enabled to preferentially store the measurement result with high priority by setting the priorities of different service types or slices or measurement configurations, so that when the QoE measurement result is suspended to be reported, the network side can preferentially obtain the measurement result of the application layer with the service type or slice or measurement configuration with high priority, the measurement requirements of operators on different service types or slices or measurement configurations are met, and network optimization is facilitated.

Example two

The embodiment provides a method for storing an application layer measurement result based on a memory, as shown in fig. 5, including the following steps:

501. the RRC layer of the terminal equipment receives the application layer measurement result of the first service type and the application layer measurement result of the second service type from the upper layer of the RRC layer.

Optionally, the first service type and the second service type may also be a first slice (slice) and a second slice, or a first measurement configuration and a second measurement configuration, and the like.

Optionally, before step 501, the terminal device receives an application layer measurement configuration from the access network device and the RRC layer of the terminal device sends the application layer measurement configuration to an upper layer of the RRC layer of the terminal device. See, for example, the description of fig. 3 above.

Optionally, before step 501, the RRC layer of the terminal device may send the first capability information to an upper layer of the RRC layer of the terminal device. Description of the first capability information refers to the description of fig. 4.

502. The RRC layer of the terminal equipment receives first indication information and second indication information from access network equipment, wherein the first indication information indicates that the terminal equipment suspends the reporting of the application layer measurement result of the first service type, and the second indication information indicates that the terminal equipment suspends the reporting of the application layer measurement result of the second service type.

Optionally, the first indication information and the second indication information may be the same information (that is, the access network device instructs the terminal device to stop reporting the application layer measurement results of two or more service types through one indication information), or may be two information (for example, carried through two signaling).

503. The RRC layer of the terminal equipment stores the measurement result of the application layer of the first service type in a first memory space; and the RRC layer of the terminal equipment stores the application layer measurement result of the second service type in a second memory space.

The application layer measurement result of the first service type and the application layer measurement result of the second service type use different memory spaces and can be independent of each other. And when the memory space corresponding to the application layer measurement result of the first service type is full, the storage of the application layer measurement result of the second service type is not influenced. The memory space is used for storing the measurement result of the application layer.

Optionally, the storing, by the RRC layer of the terminal device, the application layer measurement result of the first service type in the first memory space includes: when the RRC layer of the terminal device receives a new application layer measurement result of the first service type from an upper layer of the RRC layer, and when a first memory space corresponding to the application layer measurement result of the first service type is used up, the RRC layer discards the newly received application layer measurement result of the first service type.

The storing, by the RRC layer of the terminal device, the application layer measurement result of the second service type in the second memory space includes: and when the RRC layer of the terminal equipment receives a new application layer measurement result of the second service type from the upper layer of the RRC layer and a second memory space corresponding to the application layer measurement result of the second service type is used up, the RRC layer discards the newly received application layer measurement result of the second service type.

Steps 501 and 502 do not define a precedence order. Before the RRC layer of the terminal device receives the first indication information and the second indication information from the access network device, the RRC layer of the terminal device may not receive the application layer measurement result of the first service type and the application layer measurement result of the second service type.

In the implementation, the memory spaces of different service types or slices or measurement configurations are independent, and the measurement results of different service types or slices or measurement configurations do not overlap with each other, so that the storage flexibility and efficiency of the measurement results of the application layer are improved.

EXAMPLE III

The embodiment provides a method for storing an application layer measurement result based on a memory, as shown in fig. 6, including the following steps:

601. the RRC layer of the terminal equipment receives the application layer measurement result of the first service type and the application layer measurement result of the second service type from the upper layer of the RRC layer.

Optionally, before step 601, the terminal device receives the application layer measurement configuration from the access network device and the RRC layer of the terminal device sends the application layer measurement configuration to an upper layer of the RRC layer of the terminal device. See, for example, the description of fig. 3 above.

Optionally, before step 601, the RRC layer of the terminal device may send the first capability information to an upper layer of the RRC layer of the terminal device. Description of the first capability information refers to the description of fig. 4.

602. The RRC layer of the terminal equipment receives first indication information and second indication information from access network equipment, wherein the first indication information indicates that the terminal equipment suspends the reporting of the application layer measurement result of the first service type, and the second indication information indicates that the terminal equipment suspends the reporting of the application layer measurement result of the second service type.

603. And the RRC layer of the terminal equipment preferentially stores the measurement result of the application layer of the first service type, wherein the priority of the first service type is higher than that of the second service type.

Optionally, the terminal device receives, before step 603, indication information from the access network device, where the indication information indicates a priority of the first service type and a priority of the second service type, or indicates a priority of some service types, and if the access network device does not send the indication information indicating a priority of some service types, the priorities of the service types are defaulted to be the highest or the lowest.

For step 603, an optional scheme is that the preferentially storing, by the RRC layer of the terminal device, the measurement result of the application layer of the first service type includes:

For step 603, in another optional scheme, preferentially storing, by the RRC layer of the terminal device, the measurement result of the application layer of the first service type includes:

and when the memory space for storing the application layer measurement result is used up, the RRC layer deletes the application layer measurement result of the second service type which is stored and does not receive the ending instruction, and stores the newly received application layer measurement result of the first service type. The RRC layer does not delete the stored application layer measurement results of the second service type for which the end indication has been received.

In the case of memory space exhaustion: and for the stored application layer measurement result of the second service type, if the RRC layer does not receive the ending instruction corresponding to the measurement result, deleting the application layer measurement result of the second service type which does not receive the ending instruction when receiving the application layer measurement result of the new first service type, and storing the application layer measurement result of the newly received first service type. If the stored application layer measurement result of the second service type has received the end indication, the application layer measurement result of the second service type is not deleted when the application layer measurement result of the new first service type is received. And if the other application layer measurement results cannot be deleted, discarding the newly received application layer measurement result of the first service type.

When the upper layer of the RRC layer of the UE receives the measurement configuration of the application layer and when the service corresponding to the service type is started, the UE starts the corresponding measurement of the application layer. When the upper layer of the RRC layer of the UE starts the application layer measurement, the upper layer of the RRC 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, which slices (slices) in the service type have started application layer measurement (for example, carrying single network slice selection assistance information (S-NSSAI)), and a recording session indication (recorded 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, an upper layer of an RRC 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 upper layer of the RRC layer of the UE finishes the application layer measurement, the upper layer of the RRC 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 comprises 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).

The stored application layer measurement result that receives the end instruction means that the RRC layer of the UE receives the end instruction corresponding to the session corresponding to the application measurement result. Since it makes sense only to obtain complete application layer measurements for a session, if the saved application layer measurements for which an end indication was received are deleted, it makes no sense for those application layer measurements for the session that the terminal device has previously sent to the access network device.

Steps 601 and 602 do not define a sequential order. Before the RRC layer of the terminal device receives the first indication information and the second indication information from the access network device, the RRC layer of the terminal device may not receive the application layer measurement result of the first service type and the application layer measurement result of the second service type.

In this embodiment, by defining the priorities of the application layer measurement results corresponding to different service types or slices or measurement configurations, when the terminal device suspends QoE measurement reporting, the application layer measurement result with a high priority is preferentially stored, which satisfies the measurement requirements of operators for different service types or slices or measurement configurations, and provides flexibility and efficiency in storing the application layer measurement result. Meanwhile, only the stored application layer measurement results which do not receive the ending instruction are deleted, so that the deletion of the application layer measurement results corresponding to the session which is ended by the application layer measurement is avoided, and the network side can obtain the complete application layer measurement results.

Example four

The embodiment provides a method for storing application layer measurement results based on a threshold, as shown in fig. 7, including the following steps:

701. the RRC layer of the terminal equipment receives the application layer measurement result of the first service type from the upper layer of the RRC layer.

Optionally, the first service type may also be a first slice (slice), a first measurement configuration, or the like.

Optionally, before step 701, the terminal device receives an application layer measurement configuration from the access network device and the RRC layer of the terminal device sends the application layer measurement configuration to an upper layer of the RRC layer of the terminal device. See, for example, the description of fig. 3 above.

Optionally, before step 701, the RRC layer of the terminal device may send the first capability information to an upper layer of the RRC layer of the terminal device. Description of the first capability information refers to the description of fig. 4.

702. And the RRC layer of the terminal equipment receives first indication information from the network equipment, and the first indication information indicates the terminal equipment to suspend the reporting of the measurement result of the application layer of the first service type.

703. And when an AS measurement result corresponding to the application layer measurement result of the first service type, or an AS measurement result when the RRC layer receives the application layer measurement result of the first service type, or a measurement result visible to access network equipment and corresponding to the application layer measurement result of the first service type meets a condition corresponding to a first threshold, the RRC layer of the terminal equipment stores the application layer measurement result of the first service type.

Optionally, when the condition corresponding to the first threshold is not satisfied, the RRC layer of the terminal device does not store the application layer measurement result of the first service type.

Optionally, the condition that the first threshold is met may be higher than the first threshold, or may be lower than the first threshold, and the present invention is not limited thereto. For example, when the AS measurement result corresponding to the application layer measurement result is lower than the first threshold, the RRC layer of the terminal device stores the application layer measurement result, so that only the application layer measurement result with the AS measurement result lower than the first threshold may be analyzed, thereby optimizing the network.

Optionally, the threshold is from the access network device. For example, the access network device carries the first threshold when sending the application layer measurement configuration or the first indication information to the terminal device. Optionally, after the RRC layer of the terminal device receives the first indication information, the terminal device will perform step 703; or after the terminal device says the application layer measurement configuration, step 703 is executed, i.e. regardless of whether the first indication information is received.

Optionally, the AS measurement result refers to signal quality (such AS RSRP/RSRQ) or packet loss rate of the serving cell. The measurement result visible to the access network device is described in the scenario corresponding to fig. 3.

In this embodiment, the steps 701 and 702 do not limit the sequence.

By the scheme for storing the application layer measurement result, the RRC layer of the terminal equipment stores the application layer measurement result only when the AS measurement result corresponding to the application layer measurement result or the measurement result visible to the access network equipment meets the condition corresponding to the first threshold, so that the application layer measurement result is selectively stored under the condition that the memory of the terminal equipment is limited, and the storage efficiency is improved.

In the first to fourth embodiments, optionally, when the RRC layer of the UE receives the indication information of suspending the reporting of QoE measurement from the access network device, how should the QoE measurement result already delivered to the PDCP layer be processed? The method comprises the following steps: the UE will continue to send these QoE measurements to the access network equipment. The second method comprises the following steps: the UE will not continue to send these QoE measurements to the access network device, and the UE will re-store QoE measurements that have not been successfully sent to the access network device (e.g., qoE measurements stored in the PDCP layer of the UE) in the RRC layer of the UE.

Optionally, the method may further include the steps of:

and step A, the access network equipment sends indication information for recovering QoE measurement report to the UE.

The access network device may simply notify the UE to suspend reporting of some QoE measurements, and the indication information may carry a service type, a slice ID, or other identifier to indicate that reporting of those QoE measurements is suspended.

Step B.UE sends the stored QoE measurement result to the access network equipment

And when the RRC layer of the UE receives the indication information for recovering the QoE measurement report from the upper layer, the RRC layer of the UE starts to send the stored QoE measurement result to the PDCP layer of the UE. Specifically, the UE generates an RRC message, where the RRC message carries one or more stored QoE measurement results. And the UE sends the QoE measurement result to the access network equipment through RRC message.

EXAMPLE five

The embodiment provides a method for storing application layer measurement results based on PDCP, as shown in fig. 8, including the following steps:

801. and the RRC layer of the terminal equipment receives first indication information from the access network equipment, and the first indication information indicates the terminal equipment to suspend the reporting of the measurement result of the application layer.

Optionally, before step 801, the terminal device receives the application layer measurement configuration from the access network device and the RRC layer of the terminal device sends the application layer measurement configuration to an upper layer of the RRC layer of the terminal device. See, for example, the description of fig. 3 above. Optionally, before step 801, the RRC layer of the terminal device may send the first capability information to an upper layer of the RRC layer of the terminal device. Description of the first capability information refers to the description of fig. 4.

802. And the RRC layer of the terminal equipment sends second indication information to the PDCP layer of the terminal equipment to indicate that the reporting of the measurement result of the application layer is suspended.

Optionally, the second indication information may further indicate that a PDCP layer of the terminal device is not to process a subsequent QoE measurement result. Optionally, after the PDCP layer of the terminal device receives the second indication information, how should the QoE measurement results already delivered to the PDCP layer be processed? The method comprises the following steps: the terminal device will continue to send these QoE measurements to the access network device. The second method comprises the following steps: the terminal device will not continue to send the QoE measurement results to the access network device, and the terminal device will recover PDCP PDUs corresponding to the QoE measurement results that have not been successfully sent to the access network device and have been processed by the PDCP layer into PDCP Service Data Units (SDUs), that is, the PDCP layer stores the measurement results that have not been successfully sent to the access network device station in the form of PDCP SDUs in the PDCP layer.

803. The PDCP layer starts a first timer, and the first timer corresponds to a first application layer measurement result newly received from the RRC layer.

After the RRC layer of the terminal device receives the first indication information, when the RRC layer of the terminal device receives a newly received first application layer measurement result from an upper layer of the RRC layer, the RRC layer of the terminal device sends the newly received first application layer measurement result to the PDCP layer. Optionally, the RRC layer of the terminal device encapsulates the first application layer result in an RRC message, and then sends the RRC message to the PDCP layer (the RRC message may be referred to as a PDCP SDU in the PDCP layer).

Optionally, the PDCP layer of the terminal device may start the first timer for the application layer measurement result received from the RRC layer after receiving the second indication information, or the PDCP layer of the terminal device may start the first timer for the application layer measurement result received from the RRC layer even if the second indication information is not received.

804. The PDCP layer discards the first application layer measurement when the first timer times out.

Optionally, when the first timer expires, the PDCP layer may discard all the application layer measurement results.

Optionally, the method further includes the steps of:

805. the PDCP layer starts a second timer corresponding to a second application layer measurement result newly received from the RRC layer;

the detailed description is similar to the description of the first timer in step 803.

806. When the second timer times out, the PDCP layer discards the second application layer measurement.

Optionally, the duration of the first timer is indicated by the access network device. For example, the duration of the first timer is indicated when the access network device issues the first indication information or the application layer measurement configuration or the access network device configures the radio signaling bearer reporting the QoE measurement result.

Optionally, the duration of the second timer is indicated by the access network device. For example, the duration of the second timer is indicated when the access network device issues the second indication information or the application layer measurement configuration or the access network device configures the radio signaling bearer reporting the QoE measurement result.

Optionally, the method further includes the steps of:

807. before the first timer is overtime, the PDCP layer saves the measurement result of the application layer of the first service type from the RRC layer as a PDCP SDU.

That is, after the PDCP layer of the terminal device receives the PDCP SDU carrying the QoE measurement result from the RRC layer of the terminal device, the PDCP layer of the terminal device does not perform the processing of the PDCP layer, that is, the QoE measurement results are only stored in the PDCP layer in the form of PDCP SDUs.

Optionally, the method further includes the steps of:

808. and the RRC layer of the terminal equipment receives third indication information from the access network equipment, and the third indication information indicates the terminal equipment to recover the reporting of the measurement result of the application layer.

809. And the RRC layer of the terminal equipment sends fourth indication information to the PDCP layer of the terminal equipment, and the fourth indication information indicates that the measurement result report of the application layer is recovered.

Alternatively, the fourth indication information may be a process of instructing the PDCP layer to recover the QoE measurement result.

By the scheme for storing the application layer measurement result, when the suspended QoE measurement report occurs, the terminal equipment stores the newly received application layer measurement result in the PDCP layer, so that special processing is not required to be performed in the RRC layer, the complexity of the terminal equipment is reduced, and the storage efficiency is improved.

Example six

The embodiment provides a method for storing an application layer measurement result by an upper layer of an AS, AS shown in fig. 9, including the following steps:

901. and the upper layer of the RRC layer of the terminal equipment receives first indication information from the RRC layer, and the first indication information indicates the terminal equipment to suspend the reporting of the measurement result of the application layer.

Optionally, the RRC layer may be another layer of the AS. The upper layer of the RRC layer may be an application layer, or may be other layers that can perform QoE measurement.

Optionally, before step 901, the terminal device receives an application layer measurement configuration from the access network device and the RRC layer of the terminal device sends the application layer measurement configuration to an upper layer of the RRC layer of the terminal device. See, for example, the description of fig. 3 above. Optionally, before step 901, the RRC layer of the terminal device may send the first capability information to an upper layer of the RRC layer of the terminal device. Description of the first capability information refers to the description of fig. 4.

902. An upper layer of an RRC layer of the terminal device obtains an application layer measurement result of the first service type.

After receiving the first indication information, the upper layer of the RRC of the terminal device continues QoE measurement, but the upper layer of the RRC of the terminal device does not process according to the reporting rule or the measurement rule in the previous application layer measurement configuration.

Optionally, if the periodic reporting or the periodic measurement is performed before, the upper layer of the RRC of the terminal device is modified to report after the service is finished; or, after receiving the indication information of resuming the QoE measurement reporting, the upper layer of the RRC layer of the terminal device reports the QoE measurement result in the time period from the suspension of QoE measurement reporting to the resumption of QoE measurement reporting; or, after the upper layer of the AS layer of the UE receives the indication information for resuming the QoE measurement reporting, the QoE measurement result reported next time by the upper layer of the RRC layer of the terminal device may include the performance of the application layer in the time period from the QoE measurement suspension to the QoE measurement reporting resumption (that is, the upper layer of the RRC layer of the terminal device continues to report according to the rule before the QoE reporting suspension, only the next QoE measurement result includes the performance of the application layer in the time period from the QoE measurement suspension to the QoE measurement reporting resumption, and may also include the performance of the application layer in other time periods.

903. And the upper layer of the RRC layer of the terminal equipment reports the measurement result of the application layer after the corresponding service is finished or after the indication information for recovering the measurement reporting of the application layer is received.

For example, pausing at time T1 and resuming at time T2, according to the rules before pausing, the UE should generate measurement results at times T0 (T1 > T0), T3 (T2 > T3> T1) and T4 (T4 > T2> T3> T1), and the QoE measurement result generated at time T4 reflects the measurement results in the time period from T3 to T4. In the scheme, after receiving the indication information for recovering the QoE measurement report, the upper layer of the AS of the UE generates a measurement result at time T4, where the measurement result reflects the measurement result in the time period from T0 to T4).

Optionally, the method may further include:

904. and the upper layer of the RRC layer of the terminal equipment receives second indication information from the RRC layer, and the second indication information indicates the terminal equipment to recover the reporting of the measurement result of the application layer.

Optionally, the upper layer of the RRC layer of the UE recovers the reporting rule or the measurement rule in the previous measurement configuration of the application layer.

By the scheme for storing the measurement result of the application layer, when the suspended QoE measurement report occurs, the upper layer of the RRC layer of the terminal equipment cannot generate the measurement result of the application layer within the suspended time period, but the upper layer of the RRC layer of the terminal equipment is still performing the measurement of the application layer, so that the subsequently generated measurement result of the application layer still indicates the measurement result of the application layer at the suspended stage, a network side still can obtain the complete measurement result of the application layer, the problem of discarding the measurement result of the application layer when the memory space is used up cannot occur, and the efficiency is improved.
