The present disclosure relates to the field of communications technologies, and in particular, to an information processing method and apparatus.

Background

In a mobile communication system, there are various communication measurement modes, which are mostly performed separately when applied to a terminal device, and each acquire a single performance of the terminal device, such as a data transmission performance, a user experience performance, or a signal level performance of the terminal device. Wherein the user experience performance belongs to one of the application layer measured performance, and the data transmission performance and the signal level performance belong to the non-application layer measured performance. When there is an application layer measurement requirement of the terminal device, the core network device or the network management device and the like can send an application layer measurement request to the terminal device, so that the terminal device executes the corresponding application layer measurement and reports the application layer measurement result. And then, the core network equipment or the network management equipment can adjust the wireless resource allocation condition of the terminal equipment according to the acquired application layer measurement result.

However, in the above manner, only the application layer measurement result of the terminal device is analyzed separately, and a single application layer measurement result cannot accurately represent the overall performance of one terminal device. The prior art determines the radio resource allocation of the terminal device based on a single measurement result, and the resource allocation is likely to be unable to match the real network performance of the terminal device due to less information utilized.

The design enables the tracking collection entity to correlate the application layer measurement result and the non-application layer measurement result of the same terminal equipment according to the identification of the terminal equipment, and realizes comprehensive analysis of the network information of each terminal equipment at the angle of each terminal equipment.

In an alternative design, the first measurement result and the second measurement result may also include the type of the terminal device.

In an alternative design, the first measurement result and the second measurement result may further include an identification of the terminal device and a type of the terminal device. Thus, the tracking and collecting entity can perform comprehensive analysis not only on the same terminal equipment, but also on each terminal equipment of the same type.

The design ensures that the tracking and collecting entity can select one content as the identification of the terminal equipment according to the own requirement, and the flexibility is good.

In an alternative design, when the identity of the terminal device includes an identity of a serving cell in which the terminal device is located and a C-RNTI of the terminal device in the serving cell: the first measurement result may include an identifier of a current serving cell in which the terminal device is located, a C-RNTI of the terminal device in the current serving cell, and a non-application layer measurement result of the terminal device in the current serving cell, and the second measurement result may include identifiers of a plurality of serving cells through which the terminal device passes in a measurement period corresponding to the second measurement result, C-RNTI of the terminal device in the plurality of serving cells, and an application layer measurement result measured by the terminal device in the measurement period corresponding to the second measurement result. In the design, the complete moving track of the terminal equipment in one measuring period is reported to the tracking and collecting entity through the access network equipment, so that the tracking and collecting entity is helped to acquire non-application layer measuring results in all service cells which the terminal equipment passes through in the measuring period according to the moving track, and the tracking and collecting entity can use the non-application layer measuring results measured in the measuring period to correlate the application layer measuring results measured in the measuring period so as to improve the correlation accuracy.

In an alternative design, the second measurement result further includes indication information, where the indication information is used to indicate a target serving cell that is located in a preset measurement range among the plurality of serving cells. In this case, the trace collection entity associates the non-application layer measurements and the application layer measurements to the terminal device, which may refer to: the tracking and collecting entity searches out a non-application layer measurement result of the target service cell corresponding to the terminal equipment according to the indication information, and then associates the non-application layer measurement result of the target service cell corresponding to the terminal equipment and an application layer measurement result of the terminal equipment in the current application layer measurement to the terminal equipment. In the design, even if the application layer measurement defines the measurement range, the tracking collection entity can only carry out the association operation of the measurement result on the service cells positioned in the measurement range according to the indication information carried in the measurement result, so as to further improve the association accuracy.

In the design, the association relation between the application layer measurement results and the non-application layer measurement results corresponding to different types is obtained by classifying different types of terminal equipment, so that the application layer measurement results of other terminal equipment belonging to the same type can be obtained by directly predicting the association relation under the condition that the number of the terminal equipment supporting the application layer measurement is small, the richness of the application layer measurement results is increased, and the radio resource allocation can be carried out on the terminal equipment of different types on the basis of finer granularity of the type of the terminal equipment, so that the balance of the radio resource allocation is further improved.

Some terms and related techniques related to the embodiments of the present application are described below.

1. And a terminal device.

The terminal device in the embodiments of the present application refers to a device that provides voice and/or data connectivity to a user. For example, may include a handheld device having wireless connectivity, an in-vehicle device, or a processing device connected to a wireless modem. The terminal device may communicate with the core network via a radio access network (radio access network, RAN), exchanging voice and/or data with the RAN. The terminal device may include a User Equipment (UE), a Mobile Station (MS), a mobile terminal device (MT), a wireless terminal device, a device-to-device (D2D) terminal device, a vehicle-to-everything (vehicle to everything, V2X) terminal device, a machine-to-machine/machine-type communications, an M2M/MTC) terminal device, an internet of things (internet of things, ioT) terminal device, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile station), a remote station (remote station), an Access Point (AP), a remote terminal device (access terminal device), a user terminal device (user agent), a user agent (user), or a user equipment (user device), etc. For example, mobile telephones (or "cellular" telephones) computers with mobile terminal devices, portable, pocket, hand-held, computer-built mobile devices, and the like may be included. Such as personal communication services (personal communication service, PCS) phones, cordless phones, session initiation protocol (session initiation protocol, SIP) phones, wireless local loop (wireless local loop, WLL) stations, personal digital assistants (personal digital assistant, PDAs), and the like. But also limited devices such as devices with lower power consumption, or devices with limited memory capabilities, or devices with limited computing capabilities, etc. Examples include bar codes, radio frequency identification (radio frequency identification, RFID), sensors, global positioning systems (global positioning system, GPS), laser scanners, and other information sensing devices. Currently, examples of some terminal devices are: a mobile phone, a tablet, a notebook, a palm, a mobile internet device (mobile internet device, MID), a wearable device, a Virtual Reality (VR) device, an augmented reality (augmented reality, AR) device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in unmanned driving (self driving), a wireless terminal device in teleoperation (remote medical surgery), a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation security (transportation safety), a wireless terminal device in smart city (smart city), a wireless terminal device in smart home (smart home), and the like.

2. An access network device.

The access network device in the embodiment of the present application refers to a RAN node (or RAN device) that accesses a terminal device to a wireless network, and may also be referred to as a base station, an access point, or a network device. The access network device communicates with the wireless terminal device over the air through one or more cells and is operable to inter-convert received air frames with network interconnect protocol (internet protocol, IP) packets as a router between the terminal device and the rest of the access network, which may include an IP network. For example, including a road side unit (RSB), which may be a fixed infrastructure entity supporting V2X applications, may exchange messages with other entities supporting V2X applications. The access network device may also coordinate attribute management for the air interface. For example, the access network device may include an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in an LTE system or advanced long term evolution (long term evolution-advanced, LTE-a), or may also include fifth generation mobile communication technology (the 5) ^th generation, 5G) next generation node bs (next generation node B, gNB) in New Radio (NR) systems. Currently, some access network devices are exemplified by: a further evolved Node B (gNB), a transmission reception point (transmission reception point, TRP), an evolved Node B (eNB), a radio network controller (radio network controller, RNC), a Node B (NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (e.g., home evolved Node B, HENB, or home Node B, HNB), a baseband unit (BBU), or a wireless fidelity (wireless fidelity, wifi) Access Point (AP), etc.

In addition, in one network architecture, the access network device may be a RAN device that includes a Centralized Unit (CU) and a Distributed Unit (DU) in a Cloud access network (Cloud radio access network, cloud RAN) system. Fig. 2 illustrates a functional division manner of such a RAN device, as shown in fig. 2, the RAN device may split all protocol layers in a protocol stack into two parts, where functions of one part of the protocol layers are centrally controlled on a CU side, and functions of part of or all of the remaining other part of the protocol layers are distributed in DUs, which are implemented by the CU centrally controlling the DUs. Among other things, protocol layers deployed in a CU may include a radio resource control (radio resource control, RRC) layer, a packet data convergence protocol (packet data convergence protocol, PDCP) layer, and a service data adaptation protocol (service data adaptation protocol, SDAP) layer, such that the CU may have processing capabilities of RRC, PDCP, and SDAP. The protocol layers deployed in the DUs may include a radio link control (radio link control, RLC) layer, a medium access control (media access control, MAC) layer, and a physical layer (PHY), so that the DUs may have processing capabilities of RLC, MAC, and PHY. It is to be understood that the above-described segmentation of functions is only one example and does not constitute a limitation on CUs and DUs. That is, the CU and the DU may further divide each layer function in the protocol stack in other manners, which is not described herein in detail in this embodiment.

In addition, the functions of the CU may be implemented by one entity or may be implemented by a different entity. For example, with continued reference to fig. 2, a Control Plane (CP) of the CU and a User Plane (UP) of the CU may be further separated to obtain CU-CP and CU-UP. The CU-CP and CU-UP may be implemented by different functional entities and may be coupled to DUs, which together complete the entire functionality of the RAN device. In one possible implementation, the CU-CP is used to implement control plane functions, e.g., the CU-CP may include an RRC layer and a control plane (PDCP-C) layer of a packet data convergence protocol. The PDCP-C layer is mainly used for encryption and decryption of control plane data, integrity protection, data transmission and the like. Correspondingly, the CU-UP is used to implement user plane functions, and may include, for example, an SDAP layer and a user plane (PDCP-U) layer of a packet data convergence protocol. The SDAP layer is mainly used for processing data of the core network and mapping a data flow (flow) obtained by processing to the data bearing main body. The PDCP-U is mainly used for encryption and decryption of a data surface, integrity protection, header compression, sequence number maintenance, data transmission and the like. With continued reference to FIG. 2, for the inner pair, CU-CP and CU-UP may be connected via an E1 interface. To the outside, CU-CP may connect to the core network via Ng interface on behalf of RAN equipment, and to the DU node via control plane (F1-C) of F1 interface. CU-UP can be connected with DU node through user plane (F1-U) of F1 interface. Furthermore, in another possible implementation, PDCP-C may also be deployed in CU-UP, which is not described too much in the present application.

3. A core network.

The core network in the embodiment of the application refers to a network for providing service support for terminal equipment. Currently, some core networks are exemplified by: access and mobility management function (access and mobility management function, AMF) entities, session management function (session management function, SMF) entities, user plane function (user plane function, UPF) entities, and the like, to name but a few. Wherein the AMF entity may be configured to be responsible for access management and mobility management of the terminal device. The SMF entity may be used to be responsible for session management, such as session establishment for a user, etc. The UPF entity may refer to a functional entity of a user plane, mainly responsible for connecting to an external network. It should be noted that, in the embodiments of the present application, an entity may also be referred to as a network element or a functional entity, for example, an AMF entity may also be referred to as an AMF network element or an AMF functional entity, and for example, an SMF entity may also be referred to as an SMF network element or an SMF functional entity.

4. The collection entity is tracked.

The tracking and collecting entity in the embodiment of the application refers to an entity capable of completing tracking and collecting work. The trace collection entity may be a network element or a functional entity independent of the core network and the access network device, or may be a network element or a functional entity in the core network or the access network device, which is not particularly limited.

5. An operations administration maintenance (operation administration and maintenance, OAM) entity.

The operation management maintenance entity in the embodiment of the present application refers to an entity capable of sending a measurement task to an access network device. The operation management maintenance entity may also send configuration information of the access network device to the access network device. The operation management maintenance entity may be a network element or a functional entity independent of the core network and the access network device.

6. Data resource bearers (data radio bearer, DRB).

The DRB in the embodiment of the present application refers to a data carrying manner for carrying data of a data plane. In a wireless network, one terminal device may communicate with a plurality of base stations, so that the wireless network can provide a communication service with high transmission efficiency to the terminal device using resources of the plurality of base stations, which is called dual-connectivity (DC). In the 5G protocol, it may also be referred to as dual connectivity (multi-radio dual connectivity, MR-DC) of multiple wireless air interfaces. Wherein a plurality of base stations in the MR-DC may have different RLC/MAC entities, respectively. The plurality of base stations may be base stations belonging to the same radio access technology (radio access technology, RAT) (e.g., all fourth generation (4G) base stations, or all fifth generation (5G) base stations), or may be base stations belonging to different RATs (e.g., one 4G base station, one 5G base station), or may be base stations belonging to the same RAT and belonging to different RATs (e.g., 4G base station, 5G base station). Fig. 3 illustrates a control plane DC-C architecture diagram under dual connectivity, and as shown in fig. 3, among a plurality of base stations, a base station having control plane signaling interaction with a core network is called a Master Node (MN), and other base stations are called Secondary Nodes (SNs). The MN and the SN are respectively connected with the terminal equipment through Uu interfaces, and are connected through a control surface Xn-C of an Xn interface. Various DCs may be included in the MR-DC, such as EN-DC, NGEN-DC, NE-DC, and NR-DC. The main base station in EN-DC is an LTE base station eNB connected to a 4G core network EPC, and the auxiliary base station in EN-DC is an NR base station. The main base station in NGEN-DC is LTE base station ng-eNB connected to 5G core network 5GC, and the auxiliary base station in NGEN-DC is NR base station. The primary base station in the NE-DC is an NR base station connected to the 5G core network 5GC, and the secondary base station in the NE-DC is an LTE base station. In the beginning of 5G, the end devices in the EN-DC network cannot camp on the NR cell, and therefore EN-DC may also be referred to as NSA. Correspondingly, an NR base station capable of camping on a terminal device can be referred to as an SA NR base station. The primary base station in NR-DC is an NR base station connected to 5G core network 5GC, and the secondary base station in NR-DC is an NR base station. For a terminal device in MR-DC, the user plane of the secondary base station may be connected to the core network to which the primary base station is connected, in which case the core network may send data directly to the terminal device via the secondary base station.

In MR-DC, there may be one primary cell (PCell) in the MN, where the PCell refers to a cell deployed at a primary frequency point and in which a terminal device initiates an initial connection establishment procedure or initiates a connection reestablishment procedure, or refers to a cell indicated as a primary cell in a handover procedure. A primary and secondary cell (primary second cell, PSCell) may exist in the SN, where PSCell refers to a cell of a terminal device initiating a random access procedure at a secondary base station, or a cell of a secondary base station initiating a random access procedure when the terminal device skips the random access procedure to initiate data transmission during a secondary base station change procedure, or a cell of a secondary base station initiating a random access during a reconfiguration procedure that performs synchronization. Since the terminal device can receive services of multiple cells under one base station at the same time, a service cell group provided by the MN for the terminal device can also be called a primary service cell group (master cell group, MCG), and similarly, a service cell group provided by the SN for the terminal device is called a secondary service cell group (secondary cell group, SCG). The MCG and the SCG each include at least one serving cell. When there is only one Serving Cell (SC) in the MCG, the SC is the PCell of the terminal device. When there is only one SC in the SCG, the SC is the PSCell of the terminal device. In the DC architecture, both PCell and PSCell in MCG and SCG may be referred to as a special cell (SpCell). When there are a plurality of SCs in the MCG or SCG, SCs other than the SpCell may be referred to as secondary cells (scells). In addition, the SCell and the SpCell in each serving cell group may also perform carrier aggregation (carrier aggregation, CA), so as to jointly provide transmission resources for the terminal device. The CA technology specifically refers to that one base station configures multiple carriers (component carrier, CC) or SC for a single terminal device, so as to perform data transmission for the terminal device through the multiple carriers. In a terminal device in RRC CONNECTED state (i.e., state rrc_connected), if CA/DC is not configured, but there is only one SC, the SC is PCell. If CA/DC is configured, the SC set is composed of sPCell and SCell. And each CC may correspond to an independent cell. For a terminal device, the sPCell and all the SCells of the terminal device may form an SC set of the terminal device, where an SC may refer to a PCell or an SCell.

In the MR-DC scenario, DRBs can be divided into three data Bearer types, MCG Bearer, SCG Bearer, and Split Bearer. Wherein, MCG Bearer means that the RLC/MAC entity of the DRB is only deployed on the primary base station, SCG Bearer means that the RLC/MAC entity of the DRB is only deployed on the secondary base station, and Split Bearer means that the RLC/MAC entity of the DRB is deployed on both the primary base station and the secondary base station. For the bearer with PDCP terminated on MN, the bearer is called as MN terminated bearer, that is, the data on downlink DL directly arrives at MN from the core network, and is sent to the terminal device through RLC/MAC after being processed by PDCP/SDAP of MN, and the data on uplink UL is sent to the core network after being processed by PDCP/SDAP of MN. Similarly, for the bearer with PDCP terminated on SN, it is called SN terminated bearer, that is, data on DL arrives directly at SN from core network, is processed by PDCP/SDAP of SN, and then sent to UE via RLC/MAC, and data on UL is processed by PDCP/SDAP of SN and then sent to core network. Further, in DC, both the primary base station and the secondary base station may have RRC entities, and both may generate RRC messages (e.g., measurement request messages, etc.). In addition, the auxiliary base station may also directly send the RRC message generated by the auxiliary base station to the terminal device, and in this case, the RRC message sent by the terminal device to the auxiliary base station may also be directly sent to the auxiliary base station, where the RRC message between the auxiliary base station and the terminal device is called SRB3. Or the auxiliary base station can also inform the main base station of the RRC message generated by the auxiliary base station and then send the RRC message to the terminal equipment by the main base station, in this case, the terminal equipment can also send the RRC message to the auxiliary base station to the main base station and then transfer the RRC message to the auxiliary base station through the main base station.

It follows that in the MR-DC scenario, the data bearer types of DRBs can be classified into MN terminated MCG bearer, MN terminated SCG bearer, MN terminated Split bearer, SN terminated MCG bearer, SN terminated SCG bearer and SN terminated Split bearer. Whereas for the terminal device, the terminal device may only see three data bearer types, MCG bearer, SCG bearer, and Split bearer. The serving cell corresponding to the MCG bearer may be at least one serving cell (such as PCell) in the MCG, the serving cell corresponding to the SCG bearer may be at least one serving cell (such as PSCell) in the SCG, and the serving cell corresponding to the Split bearer may be at least one serving cell in the MCG and at least one serving cell in the SCG.

7. Non-application layer measurements.

The embodiments of the present application will collectively refer to other measurements than the application layer measurements of the terminal device as non-application layer measurements. The non-application layer measurements may also be referred to as access layer measurements, in which case the non-application layer measurements are used to reflect the measurements of the access layer. Typical non-application layer measurements may include, for example, L2 measurements, MDT measurements, and the like. The L2 measurement may count some network performance at the network side, and the measurement result of the L2 measurement may be used for radio link management, radio resource management, and network maintenance by the operator. In some examples, the L2 measurement may be for only one terminal device, e.g., measuring traffic throughput, traffic flow, processing latency, and air interface latency, etc. for that terminal device. Reference may be made to the prior art for implementation of L2 measurement, and this application will not be described in detail. The following focuses on the relevant content of MDT measurements.

In conventional drive test operations, operators typically do a routine network coverage test at intervals (e.g., one month), and do call quality tests for specific areas for the content of customer complaints to detect and optimize problems and faults in the wireless network. However, such conventional roadmapping work is labor and object intensive and may not be able to discover network failures in time. To address these issues, MDT measurements have been made. The basic idea of MDT measurement is: the operator signs up with the terminal devices of some users in advance, so that the operator can automatically collect the measurement data of the terminal devices by measuring and receiving the sent measurement results through the terminal devices of the signed users to replace part of traditional drive test work. Compared with the traditional drive test, the MDT measurement can reduce the cost of manpower and material resources and improve the timeliness of network fault discovery.

Several types of MDT measurements are described below by way of example:

signal level measurement: such measurements may typically be performed by the terminal device and sent to the access network device after the signal level of the radio signal is measured;

Quality of service (quality of service, qos) measurements, in which case such measurements may be performed by the access network device, which may include, for example, traffic flow measurements, traffic throughput measurements, traffic delay measurements, and the like. In another case, the measurement may also be performed by the terminal device, and the Qos measurement performed by the terminal device may include, for example, an uplink processing delay measurement. In yet another case, such measurements may also be performed jointly by the access network device and the terminal device, where these measurements may include, for example, an air-interface delay measurement, which refers to a processing delay of a data packet when data communication is performed between the access network device and the terminal device, such as a time interval during which measurement data arrives at the SDAP or PDCP layer of the terminal device through the SDAP or PDCP layer of the access network device;

accessibility measurement: such measurements are typically recorded by the terminal device in case of failure of RRC connection establishment and sent to the access network device.

In the embodiment of the present application, the mode of MDT measurement may be classified into an immediate MDT measurement and a logged MDT measurement. The Immediate MDT measurement is mainly a measurement performed on a terminal device in an RRC CONNECTED state (i.e., state is rrc_connected). The Immediate MDT measurement is generally used to measure the data volume of the terminal device in the RRC connected state, the throughput rate of the network interconnection protocol (internet protocol, IP), the packet transmission delay, the packet loss rate, the processing delay, and the like. The logged MDT measurement is mainly a measurement performed on a terminal device in an IDLE state (i.e. in a state of rrc_idle) or a terminal device in an INACTIVE state (i.e. in a state of rrc_inactive), for example, when the terminal device in the IDLE state or the terminal device in the INACTIVE state reselects to a common frequency serving cell of a currently camping serving cell or reselects to an inter-frequency/inter-system neighbor serving cell broadcasted by the currently camping serving cell. The logged MDT is generally used to measure the strength of a received signal of a terminal device in an idle state or a terminal device in an RRC inactive state.

In this embodiment of the present application, the initiating manner of MDT measurement may include the following two methods:

one is Signaling Based MDT (SBMDT) measurement. The signaling-based MDT measurement is an MDT measurement initiated for a particular terminal device, e.g. the access network device is informed by the core network to initiate the MDT measurement for a particular terminal device. For signaling-based MDT measurements, the core network initiates a message for MDT measurements for the terminal device only if the user of the terminal device agrees to perform MDT measurements (i.e. the terminal device supports MDT measurements), otherwise the core network does not initiate a message for MDT measurements for the terminal device. The MDT measurement message typically carries information such as the configuration information of the MDT measurement, the IP address or Uniform resource identifier (uniform resource identifier, URI) of the trace collection entity or policy collection entity (measurement collection entity, MCE), which in computer terminology is a string that identifies a particular Internet resource name that allows the user to interact with the resources in the network via a particular protocol. The configuration information for the MDT measurements may include one or more of the following: the activation type of the MDT measurement (which may include Immediate MDT only type, logged MDT only type, immediate MDT and Trace type, etc.), the area range of the MDT measurement, the mode of the MDT measurement (e.g., the immediate MDT mode or the Logged MDT mode), and some configuration parameters of the mode (e.g., measurement events of the immediate MDT mode, logging intervals and duration of the Logged MDT mode, etc.), a list of public land mobile (public land mobile network, PLMN) based on the MDT measurement of signaling.

Another is Management Based MDT (MBMDT) measurement. The MDT measurement based on management is not the MDT measurement for a specific terminal device, but the access network device receives a message for performing the MDT measurement from an OAM entity or an Element Manager (EM) entity, and selects a suitable terminal device from the terminal devices accessing the access network device to initiate the MDT measurement based on a certain policy. For example, a policy may refer to the access network device selecting only those terminal devices that have agreed to make MDT measurements to initiate MDT measurements. And whether each terminal device agrees to perform MDT measurement may be notified to the access network device in advance by the core network, for example, when the user of the terminal device agrees to perform management-based MDT, the core network may send indication information to the access network device in advance to indicate that the user of the terminal device agrees to perform management-based MDT measurement, in which case the indication information may be "Management Based MDT Allowed indication". Alternatively, the indication information may also be an MDT indicating in which PLMNs the user agrees to perform management-based, in which case the indication information may also be a PLMN list agreeing to perform management-based MDT.

It should be noted that, the above-described signaling-based MDT measurement and management-based MDT measurement may include a logged MDT mode and an immedified MDT mode.

8. Application layer measurements.

The application layer measurement in the embodiment of the present application refers to measurement performed on the performance of the application layer of the terminal device. Typical application layer measurements may include, for example, qoE measurements. For some streaming services, such as streaming services (streaming service, SS), or voice services, such as multimedia telephony (Multimedia Telephony Service for IMS, MTSI) services of an IP multimedia system, the measurement results obtained by the non-application layer measurements can only be used to characterize the pure signal quality or the communication quality of the access layer, which does not reflect the user experience when using these services. Operators want to know the user experience so that the network quality can be better optimized to enhance the user experience. Therefore, application layer measurement on terminal equipment actually belongs to an important measurement mode for improving user network use experience. The manner of initiation of the application layer measurement can also be divided into signaling-based application layer measurement and management-based application layer measurement. For signaling-based application layer measurements, the measurement tasks may be notified by the core network to the base station to initiate application layer measurements for a particular certain terminal device. For application layer measurement based on management, instead of application layer measurement for a specific terminal device, an access network device receives a message for performing application layer measurement from an OAM entity or an element management entity, and selects an appropriate terminal device from terminal devices accessing the access network device to initiate application layer measurement based on a certain policy. When the application layer measurement is QoE measurement and the non-application layer measurement is MDT measurement, the QoE measurement task may be initiated independently of the MDT measurement task or may be initiated simultaneously with the MDT measurement task. Examples of simultaneous initiation are for example: and carrying the message corresponding to the signaling-based QoE measurement task in the message corresponding to the signaling-based MDT measurement task sent to the base station by the core network.

Fig. 4 schematically illustrates an interactive flow diagram of application layer measurement, as shown in fig. 4, the flow comprising the steps of:

step 401a or step 401b, the access network device acquires an application layer measurement request message, where the application layer measurement request message carries application layer measurement configuration information.

In an alternative embodiment, the application layer measurement configuration information may be carried in the application layer measurement request message in the form of a transparent container. A container (container) is a bearer similar to a package, and is only opened (i.e. parsed) when the container reaches a final destination, and in this embodiment, the access network device will not parse the content in the container (even if the base station has the capability to parse). In this case, since the application layer measurement is performed in the application layer of the terminal device, the container in which the application layer measurement configuration information is located is parsed only after reaching the application layer of the terminal device, and is not parsed in other layers or other devices (e.g., access network devices) except the application layer of the terminal device, but is directly encapsulated and forwarded in the form of a container. In addition, the application layer measurement request message may include other information besides the application layer measurement configuration information, for example, a region range to be measured (i.e., a preset measurement range) and/or a service type corresponding to the measurement. Such other information may not be carried in the application layer measurement request message in the form of a container and may therefore be parsed by the access network device. Alternatively, in another alternative embodiment, the application layer measurement configuration information may also be carried in an opaque container in the application layer measurement request message. In this case, other layers or other devices (e.g., access network devices) than the application layer of the terminal device may also parse the application layer measurement request message to obtain the specific content of the application layer measurement configuration information. Alternatively, in yet another alternative embodiment, a portion of the content in the application layer measurement configuration information may be carried in a transparent container form, and another portion of the content may be carried in a non-container form. The application layer measurement configuration information has a plurality of bearing modes in the application layer measurement request message, and is not described one by one.

Step 402, the access network device determines, according to the application layer measurement request message, a terminal device to perform application layer measurement.

In the embodiment of the present application, when the initiation manner of the application layer measurement is different, the manner in which the access network device determines the terminal device to perform the application layer measurement is also different. By way of example, the following are:

when the manner of initiation of the application layer measurement is signaling-based application layer measurement, the application layer measurement task is initiated by the core network, and the access network device may receive an application layer measurement request message for a specific terminal device from the core network as illustrated in step 401 a. In this case, since the access network device allocates a specific communication interface for communication between the terminal device and the core network when the terminal device accesses the core network, the access network device receives the application layer measurement request message from which communication interface, i.e. determines which terminal device is to initiate application layer measurement according to the correspondence between the communication interface and the terminal device.

When the manner of initiation of the application layer measurement is management-based application layer measurement, the application layer measurement task is initiated by an OAM entity (or Element Manager (EM) entity), and the access network device may receive a measurement request message from the OAM entity (or EM entity) as illustrated in step 401 b. In this case, the access network device may first determine, according to the limiting conditions or other factors of the area range to be measured obtained by analyzing the application layer measurement request message, which terminal devices of all terminal devices accessing the access network device meet the requirement of the application layer measurement, and then use the terminal devices meeting the requirement as the terminal devices to execute the application layer measurement.

In this embodiment of the present application, the "current application layer measurement" specifically refers to an entire application layer measurement from the start of the current measurement task to the end of the current measurement task, for example, when an application layer measurement is to be performed for a certain session, an entire measurement period from the start of the session to the end of the session is taken as a measurement period of the current application layer measurement. In addition, in one application layer measurement, the terminal device may report only one application layer measurement result, for example, report an application layer measurement result measured in the whole measurement period of one session after the end of the one session, or report multiple application layer measurement results, for example, report an application layer measurement result measured in each 5 seconds according to a period duration of 5 seconds in the one session.

It should be understood that in both of the above-described initiation modes, the access network device will treat the terminal device as the terminal device to perform the application layer measurements only when the terminal device supports the application layer measurements. Whether the terminal device supports the application layer measurement can be reported to the access network device by the terminal device, can be obtained by sending an inquiry message to the terminal device by the access network device and receiving a response message, can also be obtained by pre-configuring the access network device and the terminal device, and is not particularly limited.

It should be noted that the solution in the step 401a and the step 401b is only an alternative embodiment. In the embodiment of the present application, the access network device may also determine the terminal device that performs the application layer measurement without according to the application layer measurement message received from the core network or the OAM entity or the element management entity. For example, in another alternative embodiment, the access network device may also determine, according to its own requirements, a terminal device to perform the application layer measurements.

In step 403, the access network device sends the application layer measurement configuration information bearer in an RRC message to an Access Stratum (AS) in the terminal device that is to perform the application layer measurement.

In step 403, the data bearer of the application layer measurement configuration information in the RRC message may also be in a container form, or a non-container form, or a mixture of both, as described in step 401a or step 401 b. In addition, the RRC message may include, in addition to the configuration information of the application layer measurement, other information, for example, a service type corresponding to the measurement, so as to indicate which service type of application is to perform the application layer measurement.

In step 404, the AS in the terminal device sends the application layer measurement configuration information to an upper layer of the AS in the terminal device.

In step 404 described above, the AS may forward the application layer measurement configuration information to an upper layer of the AS, since the AS is not the final layer to perform the application layer measurement. The upper layer of the AS may refer to an application layer of the terminal device, may refer to a layer that specifically performs measurement of the application layer, or may be a layer between the application layer and the AS. When the upper layer of the AS is a layer between the application layer and the AS, the upper layer of the AS needs to further forward the application layer measurement configuration information until the application layer measurement configuration information is forwarded to the layer that is finally measured. It should be understood that, when the RRC message includes both the application layer measurement configuration information and the service type corresponding to the measurement, the AS may also send the application layer measurement configuration information and the service type to be measured to an upper layer of the AS at the same time.

In step 405, an upper layer of the AS in the terminal device performs application layer measurement, to obtain an application layer measurement result.

In this embodiment of the present application, if the upper layer of the AS receives the application layer measurement configuration information and the service type corresponding to the current measurement at the same time, the upper layer of the AS may perform the application layer measurement on the application corresponding to the service type corresponding to the current measurement according to the application layer measurement configuration information, so AS to obtain an application layer measurement result. The application layer measurements may occupy any of 1 byte to 8000 bytes.

In step 405, if the terminal device performs the application layer measurement, the access network device to which the service cell after the handover belongs may re-determine whether the service cell after the handover belongs to the area range to be measured, if so, the access network device to which the service cell after the handover belongs may send indication information for continuing to measure to the terminal device to instruct the terminal device to continue to perform measurement, or the access network device to which the service cell after the handover does not need to specifically send indication information to the terminal device, where the terminal device defaults to continue to measure. If the measurement is not performed, the access network device to which the switched service cell belongs may send the indication information of stopping the measurement to the terminal device to instruct the terminal device to suspend the measurement, or the access network device to which the switched service cell belongs may send the indication information of releasing the application layer measurement configuration information to the terminal device to instruct the terminal device to end the measurement.

In step 406, the upper layer of the AS in the terminal device reports the measurement result of the application layer to the AS in the terminal device.

In the above steps 405 and 406, the upper layer of the AS may execute the application layer measurement according to a certain set rule and report the result of the application layer measurement to the AS in the terminal device. The setting rule may be a default rule in the terminal device, or may be a rule pointed out in the application layer measurement configuration information. For example, in one possible set-up rule, the upper layer of the AS performs application layer measurements and reports the application layer measurements according to the period indicated in the application layer measurement configuration information. AS another example, in another possible setup rule, the upper layer of the AS performs application layer measurements during each session (or session of some type) and reports the application layer measurements after the session ends. Assuming that the terminal device passes through 5 service cells in a session process, the upper layer of the AS reports the application layer measurement result of the terminal device to the AS in the whole period from the beginning of the session to the end of the session.

For example, the upper layer of the AS may report the measurement result of the application layer to the AS, and may indicate the service type corresponding to the measurement to the AS.

In step 407, the AS in the terminal device sends the application layer measurement result bearer to the access network device in an RRC message.

In step 407, the data bearer of the application layer measurement result in the RRC message may be in a container form, or a non-container form, or a mixed form of both, as described in step 401a or step 401 b. Besides, the RRC message may include the application layer measurement result, and may further include a service type corresponding to the measurement, so that the access network device or other entity knows for which service type the application layer measurement result is specific to the quality of user experience.

In the above step 407, if the terminal device performs the handover of the serving cell during the process of performing the application layer measurement, the AS may send the application layer measurement result to the access network device to which the handover serving cell belongs. In this case, when the access network device to which the serving cell after handover belongs is different from the access network device to which the serving cell before handover belongs, the access network device that transmits the application layer measurement configuration information (i.e., the access network device in step 403) and the access network device that receives the application layer measurement result (i.e., the access network device in step 407) are not the same access network device. When the access network device to which the service cell after switching belongs is the same as the access network device to which the service cell before switching belongs, the access network device transmitting the application layer measurement configuration information and the access network device receiving the application layer measurement result are the same access network device.

In step 408, the access network device sends the application layer measurement result of the terminal device to the trace collection entity.

In this embodiment of the present invention, after receiving an application layer measurement result of a terminal device, a tracking and collecting entity may further determine, according to the application layer measurement result, user experience (for example, quality of call quality, fluency of watching video, etc.) of a user using an application in the terminal device, where when the user experience is poor, the tracking and collecting entity may further notify an access network device to allocate more radio resources for the terminal device, so as to improve application performance of the terminal device and improve application experience of the user.

It should be noted that, in the embodiment of the present application, the step 408 is only an optional step. In another optional implementation manner, the access network device may also determine, by using the application layer measurement result, a user experience of the user using the application in the terminal device, and further adjust, according to the application layer measurement result, a radio resource allocated to the terminal device, so as to improve application performance of the terminal device and improve application experience of the user.

The application layer measurements as illustrated in fig. 4, while enabling measurement of application layer measurements of a certain terminal device or of certain terminal devices, have some problems, such as:

In one aspect, when the application layer measurement result is sent to the trace collection entity or other entity to determine the radio resource allocation, the trace collection entity or other entity can only use a single factor of the application layer measurement result to adjust the radio resource allocation, and the application layer measurement result cannot accurately represent the comprehensive performance of a terminal device, so that the inaccurate phenomenon of resource allocation is easily caused by the manner.

And secondly, the method only depends on the application layer measurement result obtained by actual measurement, in this case, if only few terminal devices in the network support the application layer measurement, the network side can only obtain the few application layer measurement results, which can result in poor accuracy of the current network performance determined by the access network device according to the few application layer measurement results.

And thirdly, if more application layer measurement results are required to be acquired, more terminal devices can only be used for carrying out application layer measurement, or the terminal devices can periodically report the application layer measurement results to the access network device, however, the application layer measurement results are interacted in an RRC signaling mode, and network signaling overhead between the terminal devices and the access network device is increased in a mode of increasing the number of the terminal devices or in a mode of periodically reporting.

Fourth problem: in this way, in the case that the terminal device performs the serving cell handover, the terminal device and the access network device need to re-interact with related information for continuing the application layer measurement or terminating the application layer measurement, so that frequent signaling interaction is required between the terminal device and the access network device, and between the AS and the upper layer of the AS, which further increases the network signaling overhead.

Problem five: in this way, when the terminal device moves out of the area to be measured, the access network device will also issue a message for releasing the application layer measurement to the terminal device, which will cause the terminal device to directly stop the application layer measurement, so that the application layer measurement result that the terminal device has started is discarded, which is not beneficial for the access network device to collect sufficient application layer measurement results.

The following describes how the above-mentioned technical problems are solved by the specific embodiments of the present application. It should be noted that, in the following description, the trace collecting entity may be the trace collecting entity in fig. 1, or a communication device capable of supporting the trace collecting entity to implement the functions required by the method, and of course, may also be other communication devices, such as a chip or a chip system. The access network device may be the access network device 1 or the access network device 2 in fig. 1, or a communication means capable of supporting the functions required by the access network device to implement the method, but may of course also be other communication means, such as a chip or a chip system. The terminal device may be the terminal device in fig. 1, or a communication device capable of supporting the functions required by the terminal device to implement the method, but may also be other communication devices, such as a chip or a chip system.

It should be understood that the terms "system" and "network" in embodiments of the present application may be used interchangeably. "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or". "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, or c may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or plural.

And, unless otherwise specified, references to "first," "second," etc. in the embodiments herein are for distinguishing between multiple objects and not for defining the order, timing, priority, or importance of the multiple objects. For example, the first access network device and the second access network device are only intended to distinguish between the access network devices before and after the serving cell handover, or only intended to distinguish between the access network devices before and after the data bearer handover, and are not intended to indicate that the two access network devices are necessarily different access network devices, nor are they identified as being different in priority or importance, etc.

Example 1

Fig. 5 schematically shows a flow chart of an information processing method provided in an embodiment of the present application, which may be performed by an access network device and a trace collection entity, such as the access network device 1 or the access network device 2, and the trace collection entity illustrated in fig. 1. As shown in fig. 5, the method includes:

step 501, the access network device sends a first measurement result to the tracking collection entity, where the first measurement result includes a measurement result of a non-application layer of the terminal device.

In the above step 501, the measurement result of the non-application layer of the terminal device may be measured by the terminal device and reported (for example, measure a non-application layer measurement indicator related to the uplink transmission performance) to the access network device, or may be measured by the access network device, or the core network, or the operation management maintenance entity (for example, measure the air interface performance). When the terminal device performs measurement, the terminal device may report the measurement result of the non-application layer according to a periodic manner, or may report the measurement result of the non-application layer according to a fixed rule of the serving cell where the terminal device is currently located. For example, in an alternative implementation manner, if a certain serving cell is configured to report a measurement result of a non-application layer every ten minutes, after a terminal device joins the serving cell, the terminal device may report a measurement result of the non-application layer of the terminal device in the serving cell to an access network device to which the serving cell belongs every ten minutes, and after each time the access network device to which the serving cell belongs receives the measurement result of the non-application layer reported by the terminal device, the access network device may determine, in real time or by itself, when to report the measurement result of the non-application layer to a tracking collection entity.

In the embodiment of the present application, the measurement result of the non-application layer of the terminal device may include an L2 measurement result and/or an MDT measurement result. The measurement metrics of the L2 measurements may include one or more of traffic throughput, traffic data volume, and traffic transmission delay, or may also include other non-application layer measurement metrics. The MDT measurement result may be a measurement result obtained by measurement performed in an immediate MDT mode, and the measurement index of the MDT measurement result may include one or more of downlink signal quality, power headroom of a terminal device, interference power received by an access network device, data volume of uplink and downlink transmission, time delay of uplink and downlink, and packet loss rate of uplink and downlink transmission, or may further include other application layer measurement indexes. With respect to the implementation of L2 measurement and MDT measurement, reference may be made to any implementation in the art, which is not specifically limited in this application.

Step 502, the access network device sends a second measurement result to the tracking collection entity, where the second measurement result includes an application layer measurement result of the terminal device.

In step 502, the measurement result of the application layer of the terminal device may be obtained according to the measurement method of the application layer illustrated in fig. 4, or may be obtained according to the measurement method of the application layer illustrated in fig. 8, which is not described herein.

In this embodiment of the present application, the measurement result of the application layer of the terminal device may specifically refer to a QoE measurement result. Several measurement metrics corresponding to QoE measurements are described below by way of example:

average throughput: refers to the total number of bits received by the application layer of the terminal device within one measurement interval. The index is applicable to streaming service scenes, such as scenes in which a user views video using a network.

Initial play time delay: for example, a time interval from a time point when the terminal device acquires the first segment of the streaming media to a time point when the terminal device extracts the first segment of the streaming media from the client buffer.

Buffer level: the duration time that the streaming media can be played from the current playing time is referred to, when the network performance is better, the more the pre-loading resources of the streaming media are, the longer the duration time that the streaming media can be played, the higher the buffer level is.

Playing time delay: refers to the play-out delay at the start of streaming media, for example, the time interval from the moment when a trigger instruction for play/back/start is received by a dynamic adaptive streaming media (dynamic adaptive streaming over hypertext transfer protocol, DASH) player transmitted by the hypertext transfer protocol to the moment when the media is played out.

Duration of deterioration: refers to the interval between the Nepal time (NPT) corresponding to the last better frame before the playing quality of the frame is deteriorated and the Nepal time corresponding to the first better frame after the playing quality of the frame is deteriorated. Wherein, a better quality frame refers to a frame which can be completely accepted and the picture corresponding to the frame contains the correct whole content, or refers to a new frame which does not depend on any frame which has been decoded before, or refers to a new frame which only depends on the better quality frame which has been decoded before.

Continuous packet loss number: refers to the number of messages that are continuously lost in a real-time transport protocol (real-time transport protocol, RTP) scenario.

Duration of jitter: meaning that the time interval between the actual playing time of a frame and the desired playing time exceeds a threshold. The expected playing time of a frame refers to the sum of the playing time of the previous frame and a preset time interval, and the preset time interval is a time interval between the Nepal time of the current frame and the Nepal time of the previous frame.

Duration of step out: meaning that the absolute time difference between the first time difference and the second time difference exceeds a certain threshold. The first time difference refers to a time difference between a playing time of a previous frame in a video stream and a playing time of a previous frame in a voice stream, and the second time difference refers to a time difference between an expected playing time of the previous frame in the video stream and an expected playing time of the previous frame in the voice stream.

Round trip delay: refers to the extra two-way delay of the round trip time of the RTP level in the client due to buffering and other processing, e.g. RTP level- > speaker- > microphone- > RTP level.

Average code rate: refers to the bit rate at which valid media information is encoded in one measurement period.

It should be understood that the foregoing is merely illustrative of several possible application layer measurement indexes, and the terminal device in the embodiments of the present application may measure one or more of the foregoing several measurement indexes to obtain an application layer measurement result, or may, of course, obtain an application layer measurement result together with other application layer measurement indexes.

In step 503, the trace collection entity associates the non-application layer measurement result of the terminal device and the application layer measurement result of the terminal device to the terminal device.

In an alternative embodiment, when the access network device initiates the measurement of the non-application layer or the measurement of the application layer only for a certain terminal device and only reports the measurement result corresponding to the terminal device, the access network device may only carry the measurement result of the non-application layer of the terminal device in the first measurement result and carry the measurement result of the application layer of the terminal device in the second measurement result. In this way, after the tracking and collecting entity receives the first measurement result and the second measurement result, the non-application layer measurement result carried in the first measurement result and the application layer measurement result carried in the second measurement result may be directly associated, so as to associate (associate) the non-application layer measurement result of the terminal device and the application layer measurement result of the terminal device to the terminal device. In this embodiment of the present application, after the application layer measurement result and the non-application layer measurement result are associated with one terminal device, the trace collection entity may know that the application layer measurement result and the non-application layer measurement result correspond to the same terminal device. The above-mentioned application layer measurement results and non-application layer measurement results may be associated specifically by the identity of the terminal device. When the access network device initiates non-application layer measurement or application layer measurement to a plurality of (i.e. two or more) terminal devices and reports measurement results corresponding to the plurality of terminal devices, the tracking and collecting entity may establish a correlation between the non-application layer measurement result and the application layer measurement result of each terminal device. The access network device may simultaneously carry non-application layer measurement results of the plurality of terminal devices in the first measurement result, and simultaneously carry non-application layer measurement results of the plurality of terminal devices in the second measurement result, and the plurality of terminal devices included in the first measurement result and the plurality of terminal devices included in the second measurement result may be different. In this case, in order to facilitate the tracking and collecting entity to distinguish the correspondence between the non-application layer measurement result and the terminal device, the first measurement result and the second measurement result may further include device information of a plurality of terminal devices corresponding to each other, so that after receiving the first measurement result and the second measurement result, the tracking and collecting entity may further associate, according to the device information carried in the two measurement results, the application layer measurement result and the non-application layer measurement result of the terminal device having the same device information to the terminal device having the device information. Therefore, even if the non-application layer measurement and the application layer measurement of the terminal equipment are independently executed and reported, the tracking and collecting entity can find different measurement results of the terminal equipment with the same equipment information according to the equipment information carried in the measurement results, thereby providing basis for associating different measurement results of the terminal equipment with the same equipment information.

In the above embodiment, the device information of one terminal device may refer to the identity of the terminal device (specifically, refer to the second embodiment) or may refer to the type of the terminal device (specifically, refer to the third embodiment). Wherein the identification of the terminal device may comprise one or more of the following: the identification of the service cell where the terminal device is located and the C-RNTI of the service cell where the terminal device is located, the identification of a non-application layer measurement task (such as the identification of an MDT measurement task), the identification of an application layer measurement task (such as the identification of a QoE measurement task), the combined identification of the non-application layer measurement task and the identification of the application layer measurement task, and QoE reference parameters. The identification of which terminal device is included in the first measurement result and the second measurement result will be specifically described in the second embodiment and the third embodiment, and will not be described here.

In this embodiment of the present application, the non-application layer measurement and the application layer measurement may be performed in different time periods, and there is a time difference between the non-application layer measurement result and the application layer measurement result obtained by measurement in different time periods, if the measurement time is not considered, the non-application layer measurement result and the application layer measurement result obtained by measurement in different time periods may be correlated together, and the correlation result may not accurately reflect the performance of the terminal device in the same time period. Based on this, in an alternative embodiment, the first measurement result may further include first time information, where the first time information is any time information capable of indicating a time of performing the non-application layer measurement corresponding to the non-application layer measurement result in the first measurement result, and the second measurement result may further include second time information, where the second time information is any time information capable of indicating a time of performing the application layer measurement corresponding to the application layer measurement result in the second measurement result. After receiving the first measurement result and the second measurement result, the tracking and collecting entity can also judge whether the time indicated by the first time information is included in the time indicated by the second time information, and when the time indicated by the first time information is included in the time indicated by the second time information, it is indicated that the non-application layer measurement result is measured in the measurement period corresponding to the application layer measurement result, and the non-application layer measurement result has better analysis significance for the application layer measurement result, so that the tracking and collecting entity can establish association between the non-application layer measurement result and the application layer measurement result. When the time indicated by the first time information exceeds the time indicated by the second time information, it is indicated that the non-application layer measurement result is not measured in the measurement period corresponding to the application layer measurement result, for example, the non-application layer measurement result may be measured before the application layer measurement is performed, or the non-application layer measurement result may be measured after the application layer measurement is performed, and the non-application layer measurement result and the application layer measurement result do not belong to the same measurement period, in which case the analysis meaning of the non-application layer measurement result for the application layer measurement result is not great, so the trace collection entity may not establish an association between the non-application layer measurement result and the application layer measurement result.

In this embodiment of the present application, the trace collection entity may determine whether the time indicated by the first time information is included in the time indicated by the second time information by:

under the condition that the first time information is the time when the access network equipment sends the measurement task corresponding to the non-application layer measurement and the second time information is the time when the access network equipment sends the measurement task corresponding to the application layer measurement, if the time corresponding to the first time information is equal to or later than the time corresponding to the second time information, the tracking and collecting entity can consider that the time indicated by the first time information is included in the time indicated by the second time information, and if the time corresponding to the first time information is earlier than the time corresponding to the second time information, the tracking and collecting entity can consider that the time indicated by the first time information exceeds the time indicated by the second time information; or alternatively, the process may be performed,

under the condition that the first time information is the time when the access network equipment sends the non-application layer measurement result and the second time information is the time when the access network equipment sends the application layer measurement result, if the time corresponding to the first time information is earlier than or equal to the time corresponding to the second time information, the tracking and collecting entity can consider that the time indicated by the first time information is included in the time indicated by the second time information, and if the time corresponding to the first time information is later than the time corresponding to the second time information, the tracking and collecting entity can consider that the time indicated by the first time information exceeds the time indicated by the second time information; or alternatively, the process may be performed,

When the first time information is a period of executing the non-application layer measurement corresponding to the non-application layer measurement result in the first measurement result (when the measurement period corresponding to the first measurement result is a period of time from when the access network device or the core network starts the non-application layer measurement to when the non-application layer measurement is obtained in the first measurement result, for example, a period of time from a starting time of starting the measurement corresponding to the first measurement result to when the access network device or the core network obtains the non-application layer measurement result in the first measurement result, or a period of time from when the terminal device starts the non-application layer measurement to when the non-application layer measurement is obtained in the first measurement result, for example, a period of time from a starting time of starting the measurement corresponding to the application layer measurement in the second measurement result to when the terminal device obtains the non-application layer measurement result in the second measurement result, for example, a period of when the terminal device starts the whole session to be measured in the second measurement result, for example, and if the terminal device starts the terminal device obtains the non-application layer measurement result in the first measurement result, the second time information is considered to be within a first time range, and if the period of time corresponding to the starting time corresponding to the first time in the first time is included in the first time range, and the information is considered to be about the period of time information corresponding to be about the period in which is included in the first time information, the trace collection entity may consider the time indicated by the first time information to exceed the time indicated by the second time information.

It should be understood that the foregoing description is merely exemplary of several ways of determining whether the time indicated by the first time information includes the time indicated by the second time information, and the present application is not limited to the manner in which the trace collecting entity must determine, as long as it can be determined that the non-application layer measurement result is a determination manner obtained by measuring in the measurement time corresponding to the application layer measurement result, which is within the scope of protection of the present application.

In the first embodiment, by associating the non-application layer measurement result and the application layer measurement result of the terminal device, the tracking collection entity can comprehensively utilize various measurement results of the terminal device to comprehensively analyze the performance of the terminal device. This approach helps to improve the uniformity and accuracy of resource allocation to each terminal device by enabling the trace collection entity to adjust the resource allocation with reference to more information than the approach illustrated in fig. 4 where application layer measurements are analyzed in isolation to determine radio resource allocation.

Several possible implementations of the solution in embodiment one are described below with respect to embodiment two through embodiment four based on embodiment one.

Example two

Fig. 6 schematically shows a flowchart of an information processing method provided in the second embodiment of the present application, where the method may be performed by a first access network device, a second access network device, and a trace collection entity, such as the access network device 1, the access network device 2, and the trace collection entity shown in fig. 1. As shown in fig. 6, the method includes:

In step 601, the first access network device sends a first measurement result to the tracking collection entity, where the first measurement result includes an identifier of at least one terminal device and a measurement result of a non-application layer of the at least one terminal device.

In an alternative embodiment, for a terminal device, the first measurement result may include the following contents:

the identification of the current service cell where the terminal equipment is located, the C-RNTI of the terminal equipment in the current service cell and the measurement result of the non-application layer of the terminal equipment in the current service cell. Wherein the current serving cell may be one of the serving cells managed by the first access network device. For example, the current service cell sets the terminal device to report the non-application layer measurement result once every 10 minutes, then the terminal device can report the non-application layer measurement result of the terminal device in the current service cell to the first access network device once every ten minutes since the terminal device joins the current service cell, and after the first access network device receives the non-application layer measurement result, the identifier of the current service cell, the C-RNTI of the terminal device in the current service cell and the non-application layer measurement result can be reported to the tracking collection entity in real time or when the access network device decides itself. Or alternatively, the process may be performed,

The identification of the current service cell where the terminal equipment is located, the identification allocated by the CU-CP to the terminal equipment and the measurement result of the non-application layer of the terminal equipment in the current service cell. Or alternatively, the process may be performed,

the identification of the non-application layer measurement task corresponding to the terminal device (for example, the identification of the MDT measurement task) and the non-application layer measurement result of the terminal device in the current serving cell. The identification of the MDT measurement task may refer to a task number of the MDT measurement task, or may refer to a trace identification in the MDT measurement task, for example. Or alternatively, the process may be performed,

in the case that the access network device initiates the application layer measurement and the non-application layer measurement on the terminal device at the same time, the identifier of the application layer measurement task (for example, the identifier of the QoE measurement task) corresponding to the terminal device and the non-application layer measurement result of the terminal device in the current serving cell may also be included. The identification of the QoE measurement task may refer to, for example, a task number of the QoE measurement task, or may refer to a tracking identification in the QoE measurement task. Or alternatively, the process may be performed,

under the condition that the access network equipment initiates the application layer measurement and the non-application layer measurement on the terminal equipment at the same time, the QoE reference parameters corresponding to the QoE measurement task of the terminal equipment and the non-application layer measurement result of the terminal equipment in the current service cell can also be included. Wherein the QoE reference parameter is composed of three information, namely a mobile device country code (mobile country code, MCC), a mobile network code (mobile network codes, MNC) and a QoE measurement collection identity (QoE measure collection identity, QMC ID), and has global uniqueness. The QMC ID may be generated by a network manager or an operator.

In this embodiment of the present application, if the network architecture of the first access network device is shown in fig. 3, the CU and the DU in the first access network device may report, respectively, the obtained partial non-application layer measurement results to the trace collection entity, where in this case, the CU and the DU may also report, synchronously, the identities of the terminal devices corresponding to the partial non-application layer measurement results when reporting the partial non-application layer measurement results.

Step 602, the first access network device sends a second measurement result to the tracking collection entity, where the second measurement result includes an identifier of at least one terminal device and an application layer measurement result measured by the at least one terminal device in a measurement period corresponding to the second measurement result.

It should be noted that, the terminal device may periodically report the measurement result of the application layer, or may report the measurement result of the application layer after each session is ended. Examples of periodically reporting application layer measurements are: when the terminal device reports according to the period of 5 seconds, if the application layer measurement is performed for a session of 1 minute, the terminal device can report 12 application layer measurement results, and each application layer measurement result can be the application layer measurement result in the corresponding session of 5 seconds.

In an alternative embodiment, for one terminal device, the second measurement result may include the following contents:

the terminal equipment is used for measuring the identification of a plurality of service cells passing through in the whole measurement period corresponding to the second measurement result, the C-RNTI of the terminal equipment in each service cell of the plurality of service cells and the application layer measurement result obtained by the terminal equipment in the whole measurement period corresponding to the second measurement result. The first access network device may be an access network device to which a serving cell where the terminal device is located when the application layer measurement ends, or an access network device to which a serving cell where the terminal device is located when reporting an application layer measurement result corresponding to the second measurement result. For example, in the case that the terminal device is configured in the current application layer measurement task to report the application layer measurement result after each session is ended, the terminal device may start the current application layer measurement when a session is started, acquire the overall call quality of the session after the session is ended, and report the overall call quality to the first access network device accessed by the terminal device when the session is ended. For example, when the terminal device is configured in the current application layer measurement task to report the application layer measurement result once every 5 seconds, the terminal device may report the application layer measurement result within 5 seconds to the first access network device to which the terminal device is connected at the moment that the 5 seconds arrive after every 5 seconds. In addition, the first access device may obtain the identities of the plurality of serving cells and the C-RNTI of the terminal device in each of the plurality of serving cells through the entire measurement period corresponding to the second measurement result in two manners. Mode one: the first access network device may generate a serving cell list according to all the serving cells passed by the terminal device in the whole measurement time period corresponding to the second measurement result, and after receiving the application layer measurement result corresponding to the second measurement result, generate a second measurement result according to the application layer measurement result corresponding to the second measurement result, the serving cell list and the C-RNTI of the terminal device in each serving cell indicated by the serving cell list, and report the second measurement result to the tracking collection entity. The list of serving cells may include an identification of one or more serving cells of all serving cells that the terminal device passes within an entire measurement period corresponding to the second measurement result. The manner in which the first access network device determines the list of serving cells will be described in detail below and will not be described here. Mode two: the terminal equipment firstly generates a service cell list according to all the service cells passing in the whole measurement time period corresponding to the second measurement result, and then sends the service cell list, the C-RNTI of the terminal equipment in each service cell pointed out by the service cell list and the application layer measurement result corresponding to the second measurement result to the first access network equipment. The terminal device may generate a serving cell list according to a preset measurement range corresponding to the current application layer measurement and all serving cells passing through in the whole measurement time period corresponding to the second measurement result, for example, use serving cells belonging to the preset measurement range corresponding to the current application layer measurement in all serving cells passing through in the whole measurement time period corresponding to the second measurement result as the serving cell list. For an implementation manner how the terminal device obtains the preset measurement range corresponding to the current application layer measurement, refer to the third embodiment, which is not described here. Or alternatively, the process may be performed,

The terminal equipment obtains the identification of a plurality of service cells passing through in the whole measurement period corresponding to the second measurement result, the identification distributed to the terminal equipment by the CU-CP in each service cell of the plurality of service cells and the application layer measurement result measured by the terminal equipment in the whole measurement period. The method for acquiring the identifiers of the plurality of service cells passing through the whole measurement period corresponding to the second measurement result is the same as the first method. Or alternatively, the process may be performed,

the identifier of the application layer measurement task (e.g. the identifier of the QoE measurement task) and the application layer measurement result measured by the terminal device in the whole measurement period corresponding to the second measurement result. The identification of the QoE measurement task may refer to a task number of the QoE measurement task, or may refer to a tracking identification in the QoE measurement task, for example. Or alternatively, the process may be performed,

the QoE reference parameters corresponding to the QoE measurement task executed by the terminal device and the application layer measurement result obtained by the terminal device in the whole measurement period corresponding to the second measurement result. QoE reference parameters refer to the description in step 601 and are not described here. Or alternatively, the process may be performed,

in the case that the access network device initiates the application layer measurement and the non-application layer measurement on the terminal device at the same time, the method may also include an identifier of a non-application layer measurement task (for example, an identifier of an MDT measurement task) and an application layer measurement result measured by the terminal device in the whole measurement period corresponding to the second measurement result. The identification of the MDT measurement task may refer to a task number of the MDT measurement task, or may refer to a trace identification in the MDT measurement task, for example.

It should be understood that, in the above steps 601 and 602, when the access network device initiates the application layer measurement and the non-application layer measurement for the terminal device at the same time, the terminal device may use the same identifier in the whole flow of the application layer measurement and the whole flow of the non-application layer measurement. For example, if the application layer measurement configuration information of the terminal device is encapsulated in the non-application layer measurement request message and sent to the access network device, the access network device may use the task identifier of the current application layer measurement (or any other identifier as long as the same identifier is guaranteed to be used) as the identifier of the terminal device in the current application layer measurement and the identifier of the terminal device in the current non-application layer measurement at the same time, and label the identifiers in the whole application layer measurement and the non-application layer measurement. Therefore, even if the measurement results of the application layer and the measurement results of the non-application layer are respectively reported according to respective rules, the tracking and collecting entity can determine different measurement results belonging to the same terminal equipment according to the same identification carried by the tracking and collecting entity so as to facilitate the tracking and collecting entity to establish association. In this case, the access network device may previously establish a correspondence between the identifier used by the application layer measurement and the identifier used by the non-application layer measurement locally, and report the correspondence at the same time when the application layer measurement result and the non-application layer measurement result are reported, so that the trace collecting entity obtains different measurement results belonging to the same terminal device according to the correspondence.

In an alternative embodiment, when the second measurement result reported by the first access network device includes the identities of the multiple service cells that the terminal device passes through in the whole measurement period corresponding to the second measurement result, the C-RNTI of the terminal device in each of the multiple service cells, and the application layer measurement result measured by the terminal device in the whole measurement period corresponding to the second measurement result, considering that the first access network device can only actively learn the movement situation of the terminal device in each service cell managed by the first access network device, but cannot actively learn the movement situation of the terminal device in the service cells managed by other access network devices, if the terminal device moves to the service cell managed by the first access network device in the whole measurement period corresponding to the second measurement result (for example, the second access network device), the second access network device may also actively send the historical movement track list of the terminal device in the whole measurement period corresponding to the second measurement result to the first access network device. The history movement track list may include an identifier of each history serving cell passed by the terminal device before entering the serving cell managed by the first access network device in the whole measurement period corresponding to the second measurement result, and a C-RNTI of the terminal device in each history serving cell. In this case:

If the terminal equipment moves to the service cell managed by the first access network equipment only in the whole measurement period corresponding to the second measurement result, the history movement track list can only comprise the identifiers of the passed service cells of the terminal equipment in the service cells managed by the second access network equipment and the C-RNTI of the terminal equipment in each passed service cell managed by the second access network equipment;

if the terminal device moves from the serving cell managed by the other access network device (for example, the third access network device) to the serving cell managed by the second access network device within the whole measurement period corresponding to the second measurement result, and then moves from the serving cell managed by the second access network device to the serving cell managed by the first access network device, the history movement track list may include both the identifier of the serving cell through which the terminal device passes in each serving cell managed by the second access network device and the C-RNTI of each serving cell through which the terminal device passes in each serving cell managed by the second access network device, the identifier of the serving cell through which the terminal device passes in each serving cell managed by the third access network device, and the C-RNTI of each serving cell through which the terminal device passes in the third access network device. The identifier of the service cell passed by the terminal device in each service cell managed by the third access network device and the C-RNTI of the terminal device in each service cell managed by the passed third access network device may be actively sent to the second access network device by the third access network device when the terminal device moves to the service cell managed by the second access network device.

Thus, according to the above embodiment, if the terminal device performs an operation of reporting one application layer measurement result of the present application layer measurement (that is, an application layer measurement result included in the second measurement result) in the service cell managed by the first access network device, the first access network device may store therein the identities of all the service cells through which the terminal device passes in the entire measurement period corresponding to the second measurement result, CRNTI of the terminal device in each service cell of all the service cells, and the application layer measurement result measured by the terminal device in the entire measurement period corresponding to the second measurement result.

Further, on this basis, the access network device may also generate the above-mentioned serving cell list by:

if no other indication exists in the application layer measurement request message, the method indicates that all the service cells passed by the terminal equipment in the whole measurement period corresponding to the second measurement result can meet the requirement of application layer measurement, so that the access network equipment can directly generate the service cell list according to the identifiers of all the service cells passed by the terminal equipment in the whole measurement period corresponding to the second measurement result;

If the application layer measurement request message further indicates that the terminal device stops the application layer measurement in some time periods or some service cells (or indicates that the terminal device only performs the application layer measurement in some time periods or some service cells), the first access network device may further determine, according to the indication, those service cells that need to stop the measurement from all the service cells that the terminal device passes through, and then deduct, from all the service cells that the terminal device passes through, those service cells that need to stop the measurement, and then generate the service cell list according to the identities of those service cells that need to be measured. Or, the access network device may also directly generate the above-mentioned serving cell list according to the identifiers of all the serving cells passed by the terminal device in the whole measurement period corresponding to the second measurement result, where a cell indication information is further required to be carried when the second measurement result is reported, where the cell indication information is used to indicate which serving cells in the serving cell list belong to the serving cells that need to perform measurement (for example, which serving cells are in a preset measurement range).

Step 603, the tracking and collecting entity obtains an application layer measurement result and a corresponding non-application layer measurement result of the same terminal device according to the identifier of each terminal device included in the first measurement result and the identifier of each terminal device included in the second measurement result.

In this embodiment of the present invention, if the second measurement result further includes the cell indication information, the tracking and collecting entity may further screen, according to the cell indication information, those target serving cells that need to be measured from the serving cell list, and then obtain, according to the identifier of the terminal device in each target serving cell, the non-application layer measurement result of the terminal device with the identifier from the non-application layer measurement results of the terminal devices included in the first measurement result sent by the first access network device and the first measurement results sent by other access network devices, and obviously, the non-application layer measurement result of the terminal device with the identifier is actually the non-application layer measurement result of the terminal device corresponding to these target serving cells. By adopting the mode, even if the application layer measurement result is a comprehensive measurement result aiming at a plurality of service cells passing in a certain measurement time period of the application layer measurement, the non-application layer measurement result is only a single measurement result aiming at different service cells, and the tracking and collecting entity can correspondingly acquire the non-application layer measurement result of the terminal equipment corresponding to each service cell in the historical movement track according to the historical movement track of the terminal equipment for executing the application layer measurement reported by the access network equipment, thereby improving the reliability of the non-application layer measurement result and the application layer measurement result related to the same terminal equipment.

It should be understood that, in the embodiment of the present application, if the first measurement result and the second measurement result further include time information as illustrated in step 503, when the trace collection entity searches for the non-application layer measurement result, in addition to the identification of the terminal device in the target serving cell, the time when the terminal device performs the non-application layer measurement is considered, so that only the non-application layer measurement result whose time when the non-application layer measurement is performed is within the time range when the application layer measurement is performed is taken as the non-application layer measurement result to be associated with the application layer measurement result. In this way, even if one identifier is reused in different measurement processes (for example, the terminal device passes through the same service cell in different measurement processes, or a certain identifier of the terminal device is reused in different time periods, etc.), the tracking collection entity can be accurately matched with the application layer measurement result and the non-application layer measurement result obtained by the same terminal device performing measurement in the same time period according to the time information, and the association of the non-application layer measurement result and the application layer measurement result is targeted.

In this embodiment of the present application, after the tracking and collecting entity obtains the application layer measurement result and the non-application layer measurement result of the same terminal device, the radio resource allocation may be adjusted directly by using the application layer measurement result and the non-application layer measurement result of the terminal device, or the following step 604 may be executed continuously. When the wireless resource allocation is directly regulated, the tracking and collecting entity can more fully acquire various measurement results of the same terminal equipment, rather than just the measurement results of the application layer, so that the tracking and collecting entity can comprehensively evaluate the wireless performance of the terminal equipment together with various measurement results of the terminal equipment, thereby being beneficial to improving the accuracy of the wireless resource allocation for the terminal equipment based on the evaluation results. It should be understood that the trace collection entity performs radio resource allocation in an alternative embodiment, and in another alternative embodiment, the trace collection entity may also send the application layer measurement result and the non-application layer measurement result of the same terminal device obtained by association to the first access network device, so that the first access network device uses the application layer measurement result and the non-application layer measurement result of the terminal device to adjust radio resource allocation.

Step 604, the tracking and collecting entity establishes an association relationship between the application layer measurement result and the corresponding non-application layer measurement result of the same terminal device.

Optionally, the tracking and collecting entity may establish an association relationship between an application layer measurement result and a corresponding non-application layer measurement result according to an application layer measurement result and a corresponding non-application layer measurement result obtained by a terminal device in a measurement period of the current application layer measurement, may also establish an association relationship between an application layer measurement result and a corresponding non-application layer measurement result according to a first measurement result and a corresponding second measurement result in all measurement periods of the current application measurement, and may also establish an association relationship between an application layer measurement result and a corresponding non-application layer measurement result according to a first measurement result and a corresponding second measurement result in part of measurement periods of the current application measurement, which is not particularly limited.

In this embodiment, the measurement result of the application layer of one terminal device may include measurement results of a plurality of application layer measurement indexes, and the measurement result of the non-application layer of one terminal device may also include measurement results of a plurality of non-application layer measurement indexes, when the tracking and collecting entity obtains the measurement result of the application layer and the measurement result of the non-application layer of one terminal device, the tracking and collecting entity may also extract, by using a big data analysis method, the characteristics of the measurement result of each non-application layer measurement index and the characteristics of the measurement result of each application layer measurement index of the terminal device, and establish a correlation relationship between the measurement result of each application layer measurement index and the measurement result of each non-application layer measurement index according to the characteristics of the measurement result of each application layer measurement index and the characteristics of the measurement result of each non-application layer measurement index. The manner of establishing the association relationship may be set by those skilled in the art according to experience, and may include, for example, but not limited to, model training, artificial intelligence (artificial intelligence, AI) algorithm, neural network model, or the like.

Step 605, the tracking and collecting entity sends the association relationship between the application layer measurement result and the corresponding non-application layer measurement result of the same terminal device to the first access network device.

It should be understood that the trace collection entity may also send the association between the application layer measurement result and the corresponding non-application layer measurement result of the same terminal device to other access network devices, where the following operation in step 606 is performed by the other access network devices.

In step 606, the first access network device predicts the application layer measurement result of the terminal device in other measurement periods by using the association relationship between the application layer measurement result and the corresponding non-application layer measurement result of the same terminal device and the non-application layer measurement result measured by the terminal device in other measurement periods. Alternatively, the first access network device may also use the above information of the terminal device and the non-application layer measurement results of other terminal devices to predict the application layer measurement results of other terminal devices, where the prediction of the application layer measurement results obtained by other terminal devices may not be as accurate as the prediction of the application layer measurement results obtained by the same terminal device.

It should be noted that, if the tracking and collecting entity sends the association relationship between the application layer measurement result and the corresponding non-application layer measurement result to other access network devices in the step 605, other access network devices that receive the association relationship may also use the association relationship to predict the application layer measurement result of the terminal device or other terminal devices.

In the embodiment of the application, although the association relationship between the application layer measurement result and the corresponding non-application layer measurement result of the terminal device depends on the application layer measurement and the non-application layer measurement performed in the measurement period in which the application layer measurement result and the non-application layer measurement result are obtained, the association relationship can be used for characterizing the universality of the application layer measurement result and the non-application layer measurement result obtained by the terminal device or other terminal devices measured in any measurement period. Therefore, the first access network device predicts the application layer measurement results of the terminal device in other measurement periods or predicts the application layer measurement results of other terminal devices in any measurement period based on the association relation, and the accuracy of the prediction results can be ensured. In this process, other measurement periods may refer to:

a historical period of time preceding the measurement period of the application layer measurement results and the non-application layer measurement results is measured. In this case, even if there are fewer application layer measurements stored in the first access network device (for example, there are many terminal devices that perform non-application layer measurements only in the history period and do not perform application layer measurements), the first access network device can predict and obtain more application layer measurements in the history period according to the association relationship and the non-application layer measurements obtained by the history period measurement. The method is beneficial to enriching the information stored in the first access network equipment, and is convenient for subsequent analysis and display of the overall application layer performance of the terminal equipment;

The measurement results are obtained as application layer measurements for a future period after a measurement period of the application layer measurements and non-application layer measurements. In this case, the terminal device may perform the non-application layer measurement only in a future period without performing the application layer measurement, which not only helps to save network resources of the terminal device, but also does not need to frequently interact with related information of the application layer measurement between the terminal device and the first access network device, thereby also helping to save network signaling overhead between the first access network device and the terminal device. In addition, even if the terminal device does not meet the requirement of the application layer measurement (for example, moves out of the preset measurement area) in the future period, as long as the terminal device will perform the non-application layer measurement, the first access network device may continue to predict the application layer measurement result of the terminal device, so as to improve the accuracy of adjusting the radio resource allocation.

It should be noted that, in the foregoing step 605 and step 606 are only an alternative embodiment, in another alternative embodiment, the trace collecting entity may not send the association relationship to the first access network device, but may directly use the association relationship to predict an application layer measurement result corresponding to a non-application layer measurement result of any terminal device (including the terminal device or other terminal devices) that is received subsequently, and then send the predicted application layer measurement result to the first access network device. This approach not only allows the first access network device to perform radio resource allocation based on more application layer measurements, but also relieves the operating pressure of the first access network device. Or the tracking and collecting entity can also determine a radio resource allocation strategy according to the application layer measurement result predicted by the tracking and collecting entity and send the radio resource allocation strategy to the first access network device, so that the first access network device adjusts the radio resource allocation according to the radio resource allocation strategy to further reduce the working pressure of the first access network device.

In the second embodiment, the access network device carries the identifier of the terminal device when reporting the measurement result of the application layer and the measurement result of the non-application layer, so that the tracking collection entity can establish the association relationship between the measurement result of the application layer and the measurement result of the non-application layer of the same terminal device, thereby facilitating the decision of the radio resource allocation by using more sufficient information later (i.e. solving the problem one illustrated in fig. 4). Furthermore, by predicting the application layer measurement results in other measurement periods by using the association relationship between the application layer measurement results and the non-application layer measurement results measured in one measurement period or multiple measurement periods, not only the dependence on the actually performed application layer measurement can be reduced when the application layer performance of the terminal device is analyzed, but also the terminal device can be enabled to not need to report the application layer measurement results frequently and periodically, thereby further helping to save the signaling overhead of the air interface (i.e. solving the problem two and the problem three illustrated in fig. 4).

Example III

Fig. 7 schematically shows a flow chart of an information processing method provided in embodiment three of the present application, which may be performed by an access network device and a trace collection entity, such as the access network device 1 or the access network device 2, and the trace collection entity illustrated in fig. 1. As shown in fig. 6, the method includes:

In step 701, the first access network device sends a first measurement result to the tracking collection entity, where the first measurement result includes a type of at least one terminal device and a non-application layer measurement result of the at least one terminal device.

In this embodiment of the present application, the type of one terminal device may be a communication entity in V2X or an unmanned aerial vehicle. The communication entity in V2X may comprise, for example, a vehicle or a cell phone in V2X.

For example, if the network architecture of the first access network device is shown in fig. 3, the CU and the DU in the first access network device may report the obtained partial non-application layer measurement results to the trace collection entity, respectively, where the CU and the DU may also report the types of the terminal devices corresponding to the partial non-application layer measurement results synchronously when reporting the partial non-application layer measurement results.

It should be noted that, in the above step 701, the first access network device may also send a first measurement result to other entities (such as OAM), where the first measurement result includes a type of at least one terminal device and a non-application layer measurement result of the at least one terminal device. In this case, other entities may also learn the capabilities of a certain type of terminal device in the first access network device. When other entities acquire the type of at least one terminal device and the non-application layer measurement result of the at least one terminal device from the plurality of access network devices, other moments can acquire the overall performance of the terminal device of a certain type in the plurality of access network devices. In this way, when the network performance of different terminal devices is presented to the outside (such as an operator client), other entities can be presented according to the terminal types, so that the outside can conveniently learn the network performance corresponding to the different types of terminals, and the outside can perform targeted network performance optimization operation.

In step 702, the first access network device sends a second measurement result to the tracking collection entity, where the second measurement result includes a type of at least one terminal device and an application layer measurement result of the at least one terminal device.

In an alternative embodiment, for the step 701 or step 702, before the first access network device (or the terminal device) performs the non-application layer measurement or performs the application layer measurement, if the non-application layer measurement request message or the application layer measurement request message further indicates that the non-application layer measurement or the application layer measurement is performed only for a certain type or some types of terminal devices, the first access network device may further determine whether the type of the lower terminal device is the indicated type of the terminal device to be measured, if yes, may initiate the non-application layer measurement or the application layer measurement for the terminal device, and if not, may not initiate the non-application layer measurement or the application layer measurement for the terminal device.

In step 703, the tracking and collecting entity obtains the application layer measurement result and the corresponding non-application layer measurement result of the terminal device of the same type according to the type of each terminal device included in the first measurement result and the type of each terminal device included in the second measurement result.

It should be noted that, the trace collection entity may first obtain, by using the method in the second embodiment, an application layer measurement result and a corresponding non-application layer measurement result of the same terminal device in the current application layer measurement or a certain measurement period of the current application layer measurement, and then obtain an application layer measurement result and a corresponding non-application layer measurement result of the same type of terminal device in the current application layer measurement or a certain measurement period of the current application layer measurement. Of course, the tracking and collecting entity may not need to obtain the application layer measurement result and the corresponding non-application layer measurement result of the same terminal device in the current application layer measurement or a certain or certain measurement periods of the current application layer measurement, but may only know the application layer measurement result and the non-application layer measurement result of the terminal device belonging to the same type.

In the embodiment of the invention, the tracking and collecting entity can classify the application layer measurement result and the non-application layer measurement result of the terminal equipment of the same type into one type directly according to the types of the terminal equipment included in the first measurement result and the second measurement result, so that operators or equipment providers can better know network performances corresponding to the terminal equipment of different types, and the operators or equipment providers can conveniently allocate radio resources based on the network performances of the terminal equipment of various types.

Step 704, the tracking and collecting entity establishes an association relationship between the application layer measurement result and the corresponding non-application layer measurement result of the same type of terminal device.

In this embodiment of the present application, the process of establishing the association relationship may refer to step 604 described above. The only differences are: step 704 may be to establish an association between the application layer measurement results and the non-application layer measurement results of a plurality of terminal devices of the same type, and step 604 is to establish an association between the application layer measurement results and the non-application layer measurement results of the same terminal device. In this embodiment of the present application, after the application layer measurement result and the non-application layer measurement result are associated with the same type of terminal device, the trace collection entity may know that the application layer measurement result and the non-application layer measurement result correspond to the same type of terminal device. The above-mentioned application layer measurement results and non-application layer measurement results may be associated specifically by the type of the terminal device.

It should be noted that, the tracking and collecting entity may first establish an association relationship between an application layer measurement result and a non-application layer measurement result of the same terminal device by using the method in the second embodiment, and then obtain the association relationship between the application layer measurement result and the non-application layer measurement result corresponding to the same type of terminal device according to the association relationship of a plurality of terminal devices belonging to the same type. Of course, the tracking and collecting entity may not need to establish the association relationship between the application layer measurement result and the non-application layer measurement result of the same terminal device, but may directly obtain the association relationship between the application layer measurement result and the non-application layer measurement result corresponding to the terminal device of the same type according to the application layer measurement results and the non-application layer measurement results of the plurality of terminal devices of the same type.

Step 705, the tracking and collecting entity sends the association relation between the application layer measurement result and the corresponding non-application layer measurement result of the terminal device of the same type and the corresponding type to the first access network device.

It should be understood that the trace collection entity may also send the association between the application layer measurements and the corresponding non-application layer measurements of the same type of terminal device to other access network devices, where the following operations in step 706 are performed.

In step 706, the first access network device predicts an application layer measurement result of the terminal device of the type using the association relationship and a non-application layer measurement result of the terminal device of the type.

In the embodiment of the present application, the association relationship corresponding to each type of terminal device may be different. When the first access network device predicts the application layer measurement result of the terminal device belonging to the type by using the association relationship, the terminal device belonging to the type may refer to:

among the terminal devices of this type, the terminal device that does not support the application layer measurement. Therefore, even if only few terminal devices support application layer measurement in the current network, the first access network device can predict the application layer measurement result of the terminal devices which do not support application layer measurement in each type according to the association relation corresponding to each type, so that the accuracy of the current network performance analysis can be improved through the sufficient application layer measurement result; and/or the number of the groups of groups,

Among the terminal devices of this type, the terminal device supporting the application layer measurement. In this way, the terminal device belonging to the type can indirectly predict the application layer measurement results of other secondary application layer measurements through the association relationship even if the application layer measurement is not frequently executed, so as to save network signaling overhead between the first access network device and the terminal device.

It should be noted that, if the tracking and collecting entity sends the association relationship between the application layer measurement result and the corresponding non-application layer measurement result to other access network devices in the step 705, other access network devices that receive the association relationship may also use the association relationship to predict the application layer measurement result of the terminal device of the type.

It should be noted that, in the foregoing step 705 and step 706 are just an alternative embodiment, in another alternative embodiment, the trace collection entity may not send the association relationship and the corresponding type to the first access network device or other access network devices, but may directly predict the application layer measurement result of the other terminal devices of the type by using the association relationship, and then send the predicted application layer measurement result to the first access network device or other access network devices, or may determine a radio resource allocation policy according to the application layer measurement result predicted by itself and send the radio resource allocation policy to the first access network device or other access network devices, so that the first access network device or other access network devices adjust radio resource allocation according to the radio resource allocation policy. The embodiment can reduce the working pressure of the first access network equipment or other access network equipment by sharing the prediction work of the first access network equipment or other access network equipment through the tracking and collecting entity.

In the third embodiment, by classifying the association relationship between the application layer measurement result and the non-application layer measurement result corresponding to each type of terminal device, the operator or the equipment manufacturer can better understand the network performance corresponding to different types of terminal devices, which is helpful for adjusting the radio resource allocation from finer granularity (i.e. solving the problem one illustrated in fig. 4). Furthermore, by predicting the application layer measurement results of other terminal devices of a certain type or other application layer measurement results of other terminal devices of the certain type by using the association relation of the terminal devices of the certain type, not only the richness of the application layer measurement results can be increased, but also the signaling overhead of the air interface can be saved (i.e. the problem two and the problem three illustrated in fig. 4 are solved).

It should be noted that, in the first embodiment and the third embodiment, the trace collecting entity may be an access network device or other entity devices capable of performing big data analysis. When the tracking and collecting entity is the access network device, the access network device does not perceive the non-application layer measurement result in the original evolution process (i.e. the original access network device does not analyze the non-application layer measurement result, for example, only performs the forwarding operation and does not use the non-application layer measurement result to perform other operations), but after the access network device is improved according to the scheme in the first embodiment, the access network device perceives the non-application layer measurement result, and predicts more application layer measurement results according to the non-application layer measurement result perceived by the access network device so as to improve the capability of performing radio resource allocation.

Example IV

Fig. 8 schematically shows a flow chart of an information processing method provided in the fourth embodiment of the present application, where the method may be performed by a core network or OAM, a terminal device, an access network device, and a trace collection entity, such as the core network or OAM, the terminal device, the access network device 1, or the access network device 2, and the trace collection entity shown in fig. 1. As shown in fig. 8, the method includes:

in step 801, the access network device receives an application layer measurement request message from a core network or an operation management maintenance entity, where the application layer measurement request message carries application layer measurement configuration information and a preset measurement range.

For example, the application layer measurement configuration information may be carried in the application layer measurement request message in the form of a container or may be carried in the form of a non-transparent container, or a part of the application layer measurement configuration information is carried in the form of a transparent container, and the other part is carried in the application layer measurement request message in the form of a non-container, and the preset measurement range may be carried in the application layer measurement request message in the form of a non-container. Besides, the application layer measurement request message may include other information besides the application layer measurement configuration information and the preset measurement range, for example, the service type corresponding to the current application layer measurement. Under the condition that the application layer measurement request message simultaneously comprises application layer measurement configuration information, a preset measurement range and a service type corresponding to the current application layer measurement, the application layer measurement request message indicates which service type of the terminal equipment in which measurement range the current application layer measurement is performed on, the current application layer measurement can also be performed on multiple service types in multiple measurement ranges, the multiple measurement ranges and the multiple service types can be in one-to-one correspondence, can also be in one-to-many correspondence, can also be in many-to-one correspondence, and is not particularly limited.

Step 802, the access network device determines, according to the application layer measurement request message, a terminal device to perform application layer measurement.

In this embodiment of the present application, the access network device may determine, with reference to the content described in step 402, a terminal device to perform application layer measurement, for example, when the application layer measurement is the application layer measurement based on signaling, the access network device may take the terminal device as the terminal device to perform application layer measurement when determining that the terminal device corresponding to the signaling supports application layer measurement, and of course, the access network device may also directly take the terminal device as the terminal device to perform application layer measurement. When the application layer measurement is based on management, the access network device can screen out terminal devices supporting the application layer measurement and located in a preset measurement range from all terminal devices accessing to each service cell managed by the access network device as terminal devices for executing the application layer measurement, and the description is not repeated here.

In step 803, the access network device sends the application layer measurement configuration information and the preset measurement range bearer in an RRC message to an Access Stratum (AS) in the terminal device that is to perform the application layer measurement.

For example, the application layer measurement configuration information may be carried in the RRC message in a container form, or may be carried in a non-transparent container form, or a part of the application layer measurement configuration information may be carried in the RRC message in a transparent container form, and another part of the application layer measurement configuration information may be carried in the RRC message in a non-container form, and the preset measurement range may be carried in the RRC message in a non-container form. Besides, the RRC message may include other information besides the configuration information of the application layer measurement and the preset measurement range, for example, the service type corresponding to the current application layer measurement.

In step 804, the AS in the terminal device parses the RRC message to obtain the application layer measurement configuration information and the preset measurement range, and sends the application layer measurement configuration information to an upper layer of the AS in the terminal device.

In step 805, an upper layer of the AS in the terminal device performs application layer measurement according to the application layer measurement configuration information.

Step 806, in the process of application layer measurement, when the terminal device needs to be triggered to switch from the first serving cell to the second serving cell, or when the data bearer of the terminal device needs to be triggered to switch from the first serving cell to the second serving cell, the access network device sends the indication information of switching cells to the AS of the terminal device.

In step 806, the indication information of the handover cell may be carried in an RRC message, and the indication information of the handover cell may be used to indicate the second serving cell. And, the access network device may specifically send the indication information for switching the cell to the RRC layer of the terminal device. The indication information may be, for example, a reconfiguration (reconfigurationWithSync, RWS) function for performing synchronization in the RRC message, or may be a function for notifying the terminal device to perform bearer type change at the network side.

Step 807, the AS of the terminal device determines whether the second serving cell indicated by the indication information of the handover cell is located within the preset measurement range, if so, step 805 is executed, and if not, step 808 is executed.

In this embodiment of the present application, if the second serving cell is located in the preset measurement range, the terminal device needs to continuously perform the application layer measurement in the second serving cell even if the terminal device or the data bearer of the terminal device is switched to the second serving cell. In this case, the AS of the terminal device may not respond so that an upper layer of the AS of the terminal device continues to perform the application layer measurement.

In step 808, the AS of the terminal device transmits indication information for suspending the measurement to an upper layer of the AS of the terminal device.

In this embodiment of the present application, the indication information of the suspension measurement may be used to instruct the upper layer of the AS to suspend the application layer measurement, or may be used to instruct those application layer measurements (such AS sessions or videos) of the application layer measurement results that have already started to record, to continue the application layer measurement and to continue recording the application layer measurement results, but those sessions or videos that have not been started before or are started later in the second serving cell do not perform the application layer measurement and recording. If the latter method is adopted, the measurement started can be kept continuously when the terminal equipment moves out of the measurement range, so that the application layer measurement result started by the terminal equipment is not discarded, thereby helping the access network equipment to collect sufficient application layer measurement result.

In an alternative implementation manner, when sending the indication information of the suspended measurement to an upper layer of the AS, the AS of the terminal device may also send the service type corresponding to the indication information of the suspended measurement at the same time. In this case, the indication information of suspending the measurement is used to indicate that the application layer measurement of the traffic type is suspended and the application layer measurement of the other traffic type is not suspended.

In step 809, the upper layer of the AS of the terminal device suspends the application layer measurement in the second serving cell according to the indication information of suspending the measurement.

In this embodiment, after the terminal device moves out of the second serving cell, steps 806 to 809 may be repeatedly performed between the access network device and the terminal device.

Alternatively, the schemes in steps 807 to 809 described above are just one alternative embodiment. In another alternative embodiment, in step 804, the AS in the terminal device may further parse the RRC message to obtain application layer measurement configuration information and a preset measurement range, and send the application layer measurement configuration information and the preset measurement range to an upper layer of the AS in the terminal device. After step 806, the AS layer of the terminal device may further send information about the second serving cell to an upper layer of the AS layer, where the upper layer of the AS layer determines whether the second serving cell belongs to a preset measurement range. If so, the upper layer of the AS layer may continue to perform the application layer measurements, otherwise, the upper layer of the AS may suspend the application layer measurements, or may continue the application layer measurements for those application layer measurements (e.g., sessions or videos) for which recording of the application layer measurements has already begun and continue recording the application layer measurements, but those sessions or videos that have not been started before or subsequently started in the second serving cell may not perform the application layer measurements and recordings. Optionally, when sending the related information of the second serving cell to an upper layer of the AS, the AS of the terminal device may also send the service type corresponding to the data bearer switched to the second serving cell at the same time.

And step 810, when the upper layer of the AS in the terminal equipment determines that the application layer measurement result needs to be reported, reporting the application layer measurement result to the AS in the terminal equipment.

For example, if the application layer measurements are performed in a per session fashion, it may be determined that the application layer measurements need to be reported after each session is completed. If the application layer measurement is performed in a periodic manner, it is determined that the application layer measurement result needs to be reported after a period of time.

In step 811, the AS in the terminal device sends the application layer measurement result bearer to the access network device in an RRC message.

Step 812, the access network device sends the application layer measurement result of the terminal device to the trace collection entity.

Illustratively, after step 812, the trace collection entity may also associate the application layer measurements and the non-application layer measurements of the terminal device according to the schemes in embodiments one through three.

It should be noted that the execution sequence of the steps 805 to 812 is not limited in the present application.

In the fourth embodiment, the access network device synchronously issues the measurement range corresponding to the application layer measurement to the terminal device, so that the terminal device can decide whether to continue to execute the application layer measurement or suspend the application layer measurement according to the relationship between the serving cell and the measurement range after the cell switch or the data bearer switch, and frequent signaling interaction between the access network device and the terminal device is not required any more to decide whether to continue to execute the application layer measurement or suspend the application layer measurement, so that signaling overhead between the access network device and the terminal device can be effectively saved (i.e., the fourth problem illustrated in fig. 4 is solved).
