Description

[Technical Field]

[0001] This application claims priority to Chinese Patent Application No. 202310144919.7, entitled "Quality of Experience Measurement Method, Communication Apparatus, and Communication Device," filed with the State Intellectual Property Office of the People's Republic of China on February 16, 2023, the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the field of communication technology, and in particular to a quality of experience measurement method, a communication apparatus, and a communication device for improving the efficiency of QoE measurement. [Background technology]

[0003] For some streaming-type services or voice services, such as streaming services and multimedia telephony services for IP multimedia subsystem (MTSI) services, mere signal quality cannot reflect the user experience when users use these services. As a result, if operators want to know what the user experience is, the base station may initiate a quality of experience (QoE) measurement (also called application layer measurement) procedure on the user equipment (UE) to better understand the user experience when users use these services, so that the network can be optimized to improve the user experience.

[0004] In the process of a UE performing a QoE measurement task configured by an NR base station, when a radio access network (RAN) device accessed by the UE is handed over from a new radio (NR) base station to a long term evolution (LTE) base station, the measurement results reported later by the UE are not reported to the NR base station but to the LTE base station.

[0005] Currently, all the characteristics of the QoE measurement task in an NR base station can be introduced into an LTE base station by modifying the protocol standard on which the LTE base station operates to implement continuity of the QoE measurement task during handover of a UE from an NR base station to an LTE base station. For example, an NR base station supports simultaneous execution of multiple QoE measurement tasks for a UE, while an LTE base station supports execution of only one QoE measurement task for a UE at a time. Therefore, when a RAN device accessed by a UE is handed over from an NR base station to an LTE base station, the protocol standard on which the LTE base station operates needs to be modified to enable the LTE base station to simultaneously execute multiple QoE measurement tasks for the UE and implement continuity of the QoE measurement task, which increases the difficulty and complexity of implementation. Summary of the Invention

[0006] The present application provides a quality of experience measurement method, a communication apparatus, and a communication device to improve the efficiency of QoE measurement. [Means for solving the problem]

[0007] According to a first aspect, the present application provides a quality of experience measurement method, wherein a first RAN device and a second RAN device are RAN devices in different networks, the first RAN device is adapted to a QoE measurement task configured by the second RAN device, i.e., the QoE measurement task configured by the second RAN device for a UE can continue to be carried out by the first RAN device, and the second RAN device is unable to fully and completely adapt to the QoE measurement task configured by the first RAN device, i.e., the QoE measurement task configured by the first RAN device for the UE cannot continue to be fully and completely carried out by the second RAN device.

[0008] The UE accesses a first RAN device, and the first RAN device configures a QoE measurement task for the UE. There may be one or more QoE measurement tasks configured by the first RAN device for the UE, which is not limited in this application. The first RAN device sends a handover request for the UE to the second RAN device to notify the second RAN device that the UE needs to access the second RAN device. After receiving the handover request, the second RAN device is authorized to provide access handover services to the UE and sends a handover acknowledgement message to the first RAN device in response to the handover request.

[0009] The first RAN device sends an access handover command to the UE to instruct the UE to access the second RAN device. The UE may determine a target QoE measurement task among the QoE measurement tasks configured by the first RAN device for the UE based on the instruction of the access handover command, where the target QoE measurement task is a QoE measurement task that the UE will continue to execute after accessing the second RAN device.

[0010] In the present application, after a UE is handed over from a first RAN device to a second RAN device, the UE may select a target QoE measurement task to continue to be executed from the QoE measurement task configured by the first RAN device for the UE. Since the target QoE measurement task is a QoE measurement task that satisfies the protocol standard under which the second RAN device operates, the protocol standard under which the second RAN device operates does not need to be modified, thereby implementing the continuity of the QoE measurement and also improving the efficiency of the QoE measurement task.

[0011] According to the first aspect, in an optional embodiment, the first RAN device and the second RAN device may determine, in the QoE measurement task configured by the first RAN device for the UE, a specific QoE measurement task belonging to a target QoE measurement task, i.e., a specific QoE measurement task that can continue to be executed after the UE accesses the second RAN device. Thus, after determining and selecting the target QoE measurement task, the first RAN device or the second RAN device indicates the target QoE measurement task using an access handover command. Specifically, the access handover command includes first instruction information, which indicates at least one of a first QoE measurement task, a second QoE measurement task, or a third QoE measurement task, where the first QoE measurement task is a QoE measurement task that the UE continues to execute and continues to report measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE continues to report measurement results), the second QoE measurement task is a QoE measurement task that the UE continues to execute and suspends reporting measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE suspends reporting measurement results), and the third QoE measurement task is a QoE measurement task whose execution is canceled by the UE after the UE accesses the second RAN device. The UE only needs to determine the target QoE measurement task based on the instruction of the access handover command, thereby improving the efficiency of performing QoE measurements by the UE and reducing the computational load on the UE.

[0012] According to the first aspect, in an optional embodiment, the handover acknowledgement message sent by the second RAN device to the first RAN device may indicate at least one of a first QoE measurement task, a second QoE measurement task, or a third QoE measurement task, where the first QoE measurement task is a QoE measurement task that the UE continues to execute and continues to report measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE continues to report measurement results), the second QoE measurement task is a QoE measurement task that the UE continues to execute and suspends reporting measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE suspends reporting measurement results), and the third QoE measurement task is a QoE measurement task the execution of which is canceled by the UE after the UE accesses the second RAN device.

[0013] According to the first aspect, in an optional embodiment, the handover request sent by the first RAN device to the second RAN device may indicate at least one of a first QoE measurement task, a second QoE measurement task, or a third QoE measurement task, where the first QoE measurement task is a QoE measurement task that the UE continues to execute and continues to report measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE continues to report measurement results), the second QoE measurement task is a QoE measurement task that the UE continues to execute and suspends reporting measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE suspends reporting measurement results), and the third QoE measurement task is a QoE measurement task the execution of which is canceled by the UE after the UE accesses the second RAN device.

[0014] According to the first aspect, in an optional embodiment, the first RAN device may include second instruction information in the access handover command, the second instruction information indicating a third QoE measurement task, the execution of which is to be canceled by the UE after the UE accesses the second RAN device. Thus, the UE knows the QoE measurement task (i.e., the third QoE measurement task) whose execution needs to be canceled among the QoE measurement tasks configured by the first RAN device for the UE. Specifically, after the UE accesses the second RAN device, the UE may detect a QoE measurement task that is not supported by the second RAN device using a communication protocol between the UE and the second RAN device. Thus, the UE may determine, as a target QoE measurement task, a QoE measurement task that can be supported by the second RAN device, other than the third QoE measurement task, among the QoE measurement tasks configured by the first RAN device for the UE. The UE autonomously determines a target QoE measurement task so that the amount of information exchange between the first RAN device and the second RAN device is reduced and the handover efficiency of the UE to the RAN device is improved.

[0015] According to the first aspect, in an optional embodiment, when there is one target QoE measurement task determined by the UE and the target QoE measurement task can be accurately supported by the second RAN device, the UE may continue to report the measurement results of the target QoE measurement task, i.e., the target QoE measurement task is the first QoE measurement task in this application.

[0016] According to the first aspect, in an optional embodiment, when there are multiple target QoE measurement tasks determined by the UE and these target QoE measurement tasks cannot be simultaneously supported by the second RAN device, the UE may suspend reporting the measurement results of all the target QoE measurement tasks, i.e., these target QoE measurement tasks are second QoE measurement tasks in the present application.

[0017] According to the first aspect, in an optional embodiment, the access handover command includes third instruction information, and the third instruction information indicates to the UE to cancel reporting of RAN device visible measurement results. In a scenario where the first RAN device is an NR base station and the second RAN device is an LTE base station, the LTE base station cannot detect the RAN device visible measurement results. As a result, it is meaningless to report the RAN device visible measurement results to the second RAN device, and the third instruction information may indicate to the UE to cancel reporting of the RAN device visible measurement results, thereby reducing the operational load of the UE and improving the efficiency of performing QoE measurements by the UE.

[0018] According to the first aspect, in an optional embodiment, the handover request includes fourth indication information, which indicates a first MDT task and a second MDT task associated with the same QoE measurement task, where the first MDT task is an MDT task associated with the QoE measurement task when the UE accesses the first RAN device, and the second MDT task is an MDT task associated with the QoE measurement task when the UE accesses the second RAN device. After the UE reports the measurement result of the target QoE measurement task to the second RAN device, the second RAN device may determine the second MDT task corresponding to the target QoE measurement task based on the fourth indication information. In this way, even after the UE is handed over from the first RAN device to the second RAN device, the QoE measurement task is still associated with the MDT task. This simplifies the problem of continuing to identify services.

[0019] According to the first aspect, in an optional embodiment, the QoE measurement collection devices corresponding to the first RAN device and the second RAN device may be the same or different. When the first RAN device sends a handover request to the second RAN device, the handover request includes the address of the first QoE measurement collection device and the address of the second QoE measurement collection device. Regarding the addresses of the first QoE measurement collection device and the second QoE measurement collection device in the first RAN device, the CN, the OAM entity, or the EM entity includes the addresses of the first QoE measurement collection device and the second QoE measurement collection device in QoE measurement collection configuration information when initiating QoE measurement, and sends the configuration information to the first RAN device. The first QoE measurement collection device is configured to collect measurement results of the QoE measurement task from the first RAN device, and the second QoE measurement collection device is configured to collect measurement results of the QoE measurement task from the second RAN device. Therefore, after the UE is handed over to the second RAN device, the second RAN device receives the measurement result of the target QoE measurement task reported by the UE, and sends the measurement result of the target QoE measurement task to the second QoE measurement collection device based on the address of the second QoE measurement collection device. The QoE measurement collection device corresponding to the first RAN device and the QoE measurement collection device corresponding to the second RAN device are distinguished, thereby improving the management efficiency of the measurement result of the QoE measurement task.

[0078] The embodiments of the present application provide a quality of experience measurement method, a communication apparatus, and a communication device to improve the efficiency of QoE measurement.

[0082] The following explains and explains some nouns or terms used in this application, which are also used as part of the present invention.

[0083] With the construction and development of networks, the operation mode of operators is gradually changing from a single voice service to a multi-service mode in which multiple services are run in parallel.

[0084] For some streaming-type services or voice services, such as streaming services and multimedia telephony services for IP multimedia subsystem (MTSI) services, mere signal quality cannot reflect the user experience when a user uses these services. As a result, if an operator wants to know what the user experience is like, a base station may initiate a quality of experience (QoE) measurement (also called application layer measurement) procedure on a user equipment (UE) to better understand the user experience when the user uses these services, thereby optimizing the network to improve the user experience. In the QoE measurement procedure, configuration information for a QoE measurement task may be sent to the base station by a core network (CN) or an operation, administration, and maintenance (OAM) entity, and the base station then sends the configuration information to the UE. The UE performs a QoE measurement task based on the configuration information to obtain a measurement result of the QoE measurement task and transmits the measurement result to the base station. The base station finally reports the measurement results to a QoE measurement collection entity, which analyzes and evaluates the measurement results to understand the user experience.

[0085] For ease of understanding, a possible, non-limiting system architecture in a QoE measurement scenario will be described first. FIG. 1 is a diagram of a possible, non-limiting system architecture in a QoE measurement scenario. As shown in FIG. 1, a communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN device (e.g., 110a and 110b in FIG. 1 , collectively referred to as 110) and at least one UE (e.g., 120a to 120j in FIG. 1 , collectively referred to as 120). The RAN 100 may further include another RAN device, for example, a wireless relay device and / or a wireless backhaul device (not shown in FIG. 1 ). The UE 120 is connected to the RAN device 110 in a wireless manner. The RAN device 110 is connected to the core network 200 in a wireless or wired manner. The core network devices in the core network 200 and the RAN devices 110 in the RAN 100 may be different physical devices, or may be the same physical device that integrates the logical functions of the core network and the radio access network.

[0086] A core network device is a device in a core network (CN) that provides service support to a UE. Currently, some examples of core network devices are an access and mobility management function (AMF) entity, a session management function (SMF) entity, and a user plane function (UPF) entity, which are not listed here. The AMF entity may be responsible for access management and mobility management of a terminal. The SMF entity may be responsible for session management, such as user session establishment. The UPF entity may be a functional entity on the user plane, and is mainly responsible for connecting to an external network. It should be noted that entities in this application may also be referred to as network elements or functional entities. For example, an AMF entity may also be referred to as an AMF network element or an AMF functional entity. In another example, an SMF entity may also be referred to as an SMF network element or an SMF functional entity, etc.

[0087] The RAN 100 may be a cellular system associated with the 3rd generation partnership project (3GPP®), such as a 4G or 5G mobile communication system, or a future-oriented evolved system (e.g., a 6G mobile communication system). Alternatively, the RAN 100 may be an open radio access network (open RAN, O-RAN, or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (Wi-Fi®) system. Alternatively, the RAN 100 may be a communication system that integrates two or more of the aforementioned systems.

[0088] Alternatively, the RAN node 110 may be referred to as an access network device, RAN entity, or access node, and forms part of a communication system to help UEs achieve radio access. The RAN devices 110 in the communication system 10 may be the same type of node or different types of nodes. In some scenarios, the roles of the RAN device 110 and the UE 120 are relative. For example, the network element 120i in FIG. 1 may be a helicopter or an unmanned aerial vehicle and may be configured as a mobile base station. To the UE 120j accessing the RAN 100 through the network element 120i, the network element 120i is a base station. However, to the base station 110a, the network element 120i is a UE. The RAN device 110 and the UE 120 are sometimes referred to as communication devices. For example, the network elements 110a and 110b in FIG. 1 may be understood as communication devices having base station functionality, and the network elements 120a through 120j may be understood as communication devices having UE functionality.

[0089] In possible scenarios, the RAN device may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next-generation base station in a 6th generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a Wi-Fi system. The RAN device may be a macro base station (e.g., 110a in FIG. 1), a micro base station or an indoor station (e.g., 110b in FIG. 1), a relay node or a donor node, or a radio controller in a CRAN scenario. Optionally, the RAN device may also be a server, a wearable device, a vehicle, an in-vehicle device, or the like. For example, in vehicle-to-everything (V2X) technology, the access network device may be a road side unit (RSU). All or part of the functionality of a RAN device in this application may alternatively be implemented using software functions running on hardware or using virtualization functions instantiated on a platform (e.g., a cloud platform). A RAN device in this application may alternatively be a logical node, logical module, or software capable of implementing all or part of the functionality of the RAN device.

[0090] In another possible scenario, multiple RAN devices cooperate to assist UEs in performing radio access, and different RAN devices separately perform some functions of a base station. For example, a RAN device may be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU may be located separately or may be included in the same network element, such as a baseband unit (BBU). The RU may be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0091] In different systems, the CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU may also be called an O-CU (open CU), the DU may also be called an O-DU, the CU-CP may also be called an O-CU-CP, the CU-UP may also be called an O-CU-UP, and the RU may also be called an O-RU. For ease of explanation, the CU, CU-CP, CU-UP, DU, and RU are used as examples for explanation in this application. Any unit in the CU (or CU-CP or CU-UP), DU, and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0092] The UE may also be referred to as a terminal, terminal device, mobile station, or mobile terminal. The UE may be widely used in various scenarios, such as device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart clothing, smart transportation, and smart city. The UE may be a mobile phone, a tablet computer, a computer with wireless transceiver functionality, a wearable device, a vehicle, an unmanned aerial vehicle, a helicopter, an airplane, a ship, a robot, a mechanical arm, or a smart home device. In the embodiments of the present application, the device form of the UE is not limited.

[0093] In the communication system 10, the RAN devices 110 and the UEs 120 may communicate with each other via a wireless network, a wired network, or a removable storage medium. Standard communication technologies and / or protocols are used for the wireless network. The wireless network is typically the Internet, but can also be any network, including, but not limited to, Bluetooth, a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), or any combination of a mobile network, a private network, or a virtual private network. In some application scenarios, customized or dedicated data communication technologies may also be used to replace or supplement the aforementioned data communication technologies. The removable storage medium may be a Universal Serial Bus (USB) flash drive, a removable hard disk, another removable storage medium, or the like, but this is not a limitation of this application.

[0094] The following describes a QoE measurement scenario through the interaction between the RAN device 110 and the UE 120. It should be understood that in practical applications, the technical solutions provided in this application can also be applied to other "RAN devices" and "UEs" that are described differently or are of different types.

[0095] QoE measurement can be divided into signaling-based QoE measurement and management-based QoE measurement. Signaling-based QoE measurement means that the QoE measurement task is targeted to a specific UE. For example, the core network uses UE-level signaling to send configuration information for the signaling-based QoE measurement task to the base station. Management-based QoE measurement means that the QoE measurement task is not targeted to a specific UE. For example, an element management (EM) entity or an operation, administration, and maintenance (OAM) entity sends configuration information for the management-based QoE measurement to the base station, and the base station selects a portion of UEs to perform QoE measurement based on the capabilities of the UEs currently accessing the base station and other information.

[0096] 2 is a schematic flowchart of the conventional QoE measurement. As shown in FIG. 2, the procedure of the conventional QoE measurement includes the following steps:

[0097] 201: The RAN device obtains QoE measurement collection configuration information.

[0098] In a signaling-based QoE measurement scenario, the RAN obtains QoE measurement collection configuration information from the CN. The QoE measurement collection configuration information delivered by the CN is for a specific UE. For example, the CN transmits the QoE measurement collection configuration information to the UE using a RAN interface message for the specific UE. In a management-based QoE measurement scenario, the RAN obtains QoE measurement collection configuration information from an OAM entity or an EM entity (i.e., the OAM in FIG. 2 can also be replaced by an EM). The QoE measurement collection configuration information delivered by the OAM entity or the EM entity is not for a specific UE. The QoE measurement collection configuration information includes an application layer measurement configuration. For example, in practical application, if the QoE measurement collection configuration information includes one container, the application layer measurement configuration is carried in the container. Therefore, the container is also called a container for application layer measurement configuration.

[0099] It should be understood that in practical application, the CN, the OAM entity, or the EM entity may be deployed in the same entity device or in different entity devices, which is not limited in this application.

[0100] For example, the QoE measurement collection configuration information obtained by the RAN device may include the content fields shown in Table 1 below.

[0101] [Table 1-1] [Table 1-2] [Table 1-3]

[0102] Optionally, the CN or OAM entity may further inform the RAN device using the QoE measurement collection configuration information. The RAN device may configure, for the UE, specific RAN visible application layer indicators (also called RAN detectable application layer indicators), i.e., available RAN visible QoE metrics in Table 1. For example, the RAN visible application layer indicators may include the following elements: Average throughput (this indicator indicates the total number of bits received at the application layer of the UE within one measurement interval, e.g., this indicator is applicable to streaming media services); initial playback latency (this indicator indicates the initial playback latency when the streaming media begins to be presented; for example, this indicator may be defined as the time from when the first segment of media is retrieved to when the streaming media is removed from the client's buffer); and Buffer level (this indicator shows the playback period for which media data is available, starting from the current playback point); Playback latency (this indicator indicates the playback latency when streaming media begins; for example, this indicator may be specifically defined as the latency from the time a Dynamic Adaptive Streaming over HTTP (DASH) player receives a play / previous / start trigger to the time the media begins to play); and a degradation period (this indicator indicates the interval between the Nepal Time (NPT) corresponding to the previous high-quality frame before degradation and the Nepal Time corresponding to the first high-quality frame after it; a high-quality frame is either a perfectly acceptable frame, with all parts of the picture corresponding to this frame containing correct content, or it is a new frame (i.e., it does not depend on previously decoded frames) or it depends only on previously decoded high-quality frames); Number of consecutively lost packets (this indicator shows the number of consecutively lost Real-time Transport Protocol (RTP) packets), Jitter period (jitter indicates that the difference between the actual playback time of a frame and the predicted playback time exceeds a threshold, and the predicted playback time of a frame is the playback time of the previous playback frame + (the difference between the Nepalese time of the current frame and the Nepalese time of the previous playback frame)); a synchronization loss period (synchronization loss indicates that the absolute time difference between value A and value B exceeds a certain threshold, where value A is the difference between the playback time of the previous playback frame of the video stream and the playback time of the previous playback frame of the audio stream, and value B is the difference between the expected playback time of the previous playback frame of the video stream and the expected playback time of the previous playback frame of the audio stream); Round-trip latency (this indicator shows the round-trip time at the RTP level plus the additional latency in two directions (RTP level → speaker → microphone → RTP level) caused by buffering and other processing at the client), and the average bit rate (this indicator shows the bit rate at which the valid media information is encoded in the measurement period); comparable quality viewport switching latency (this indicator reports latency and quality-related factors when quality degrades due to viewport movement, including quality ranking value and resolution); and Freeze (this indicator shows whether or for how long a freeze has occurred in the video stream playback process) and may include:

[0103] It should be understood that the elements included in the RAN visible application layer indicator are merely examples for illustration purposes. In practical applications, the RAN visible application layer indicator may alternatively have other content formats, which are not limited in this application.

[0104] In practical application, in the QoE measurement collection configuration information, the aforementioned "application layer measurement configuration" does not need to be transmitted to the RAN device in the form of a container, but may be transmitted to the RAN device in another RAN-detectable format, which is not limited in this application.

[0105] Typically, the QoE measurement collection configuration information sent by the CN or OAM entity to the RAN device may further include a QoE reference and the address of a measurement collection entity (MCE). For example, the address of the MCE may be described using the IP address of the MCE, or the address of the MCE may be described in another way, which is not specifically limited herein. The QoE reference is used to identify a specific QoE measurement task initiated by the network (or used to identify a specific QoE measurement task in the RAN device and the MCE) (which may be called a QoE measurement identifier). That is, each QoE measurement task corresponds to one QoE reference, and the QoE reference is a globally unique identifier. For example, the QoE reference may consist of a public land mobile network (PLMN) and a QoE measurement collection identifier, where the PLMN consists of a mobile country code (MCC) and a mobile network code (MNC), and the QoE measurement collection identifier is assigned by a management system or an operator. The IP address of the MCE is used by the base station to send corresponding measurement results to the MCE after the RAN device receives the measurement results reported by the UE.

[0106] In practical application, in addition to the QoE measurement performed for a specific service of the UE, MDT measurement may also be performed for the UE. The QoE measurement task and the MDT task are performed for the same service, and then based on the association relationship between the measurement result of the QoE measurement task and the measurement result of the MDT task, it can be known whether the degradation of the measurement result of the QoE measurement task is caused by signal quality or wireless side scheduling, so that the problem can be identified.

[0107] The basic idea of ​​MDT technology is that operators subscribe to commercial user equipment terminals to perform measurements and transmit the measurement results to replace some of the traditional drive test operations, in order to automatically collect terminal measurement data and detect and optimize problems and faults in wireless networks. The application scenario of this technology is as follows: operators typically perform regular monthly network coverage drive tests and also perform call quality drive tests in certain areas to address user complaints. MDT can be used to replace all tests in these scenarios. Existing MDT technology can include several measurement types:

[0108] 1. Signal level measurement: The UE measures the signal level of the radio signal and sends the measurement result to the base station or base station controller.

[0109] 2. Quality of service (QoS) measurements: Typically, QoS measurements (e.g., service traffic, service throughput, or service latency) may be performed by the base station, or measured by the UE (e.g., uplink processing latency), or may be jointly processed by the base station and the UE (e.g., air interface latency measurements, i.e., measuring the time of a data packet from the service data adaptation protocol (SDAP) / packet data convergence protocol (PDCP) layer of the base station to the SDAP / PDCP layer of the UE).

[0110] 3. Accessibility Measurement: The UE records information about Radio Resource Control (RRC) connection establishment failures and sends the information to the base station or base station controller.

[0111] MDT includes logged MDT and immediate MDT. Immediate MDT is a measurement mainly performed for UEs in the RRC connected state, while logged MDT is a measurement mainly performed for UEs in the idle state or RRC inactive state. For example, logged MDT may be a measurement performed by an idle or inactive UE on a cell of a frequency corresponding to the cell on which the UE is currently camped and a corresponding inter-frequency / inter-system neighbor cell for cell reselection broadcast in the cell on which the UE is currently camped. Typically, immediate MDT is used to measure UE data volume, IP throughput, packet transmission latency, packet loss rate, processing latency, etc. Logged MDT is typically a measurement performed by a UE on received signal strength.

[0112] Optionally, the QoE measurement collection configuration information sent by the CN or OAM entity to the RAN device may further include information about a minimization of drive tests (MDT) task associated with the QoE measurement task, i.e., may indicate that an association between the QoE measurement task and an MDT task needs to be performed, and may be, for example, a trace ID (also referred to as an MDT task identifier) ​​corresponding to a signaling-based MDT task. Each MDT task corresponds to one trace ID. Specifically, before or simultaneously with sending the QoE measurement collection configuration information to the RAN device, the CN or OAM entity may send configuration information of the MDT task corresponding to the trace identifier to the RAN device.

[0113] The base station initiates the MDT measurement collection task in two scenarios. One is to start a signaling-based MDT, and the other is to start a management-based MDT. The signaling-based MDT is an MDT for a specific UE. The base station receives a message to perform MDT for a specific UE from the core network (CN). The management-based MDT is not an MDT for a specific UE. The base station receives a message to perform MDT from an OAM entity or an EM entity, and the base station selects a portion of the UEs served by the base station to perform MDT measurements according to a specific side policy. In the case of signaling-based MDT, the CN does not start the signaling MDT for a UE unless the user agrees to perform MDT. For management-based MDT, when selecting a UE, the base station may consider whether the UE has agreed to perform MDT, for example, selecting only UEs that have agreed to perform MDT to perform MDT measurements (e.g., the core network notifies the base station whether a specific UE has agreed to perform MDT). Both types of MDT may include logged MDT and immediate MDT. For signaling-based MDT, the CN notifies the base station of some MDT configuration information, the IP address of a trace collection entity (TCE), or MCE. The MDT configuration information includes the MDT activation type (e.g., Immediate MDT only, Logged MDT only, or Immediate MDT and Trace), the PLMN list for signaling-based MDT, the MDT area range, the MDT mode, and the configuration parameters of the corresponding mode (e.g., immediate MDT measurement event, logged MDT recording interval, and duration). In practical application, the TCE and MCE may be the same entity device or different entity devices.

[0114] 202: The RAN device sends an application layer measurement configuration to the UE.

[0115] For signaling-based QoE measurement, the RAN device determines whether to configure QoE measurement for the UE according to whether the UE supports QoE measurement, and then the RAN sends the application layer measurement configuration to the corresponding UE.

[0116] For management-based QoE measurement, the RAN device selects an appropriate UE to perform QoE measurement based on the QoE measurement collection configuration information sent by the OAM entity or EM entity, whether the UE supports the corresponding QoE measurement, and some other factors. After selecting the UE, the RAN device sends an application layer measurement configuration to the UE.

[0117] The RAN sends the application layer measurement configuration obtained from the CN, the OAM entity, or the EM entity to the UE using an RRC message, and the message also carries the service type corresponding to the application layer measurement configuration, for example, a streaming service or a multimedia telephony service for IP multimedia subsystem (MTSI service).

[0118] In practical application, in addition to sending the application layer measurement configuration to the UE, the RAN device may further deliver other configuration information (which may be referred to as a RAN-visible application layer measurement configuration) to the UE, indicating the UE to report some application layer indicators in a RAN-device-detectable or visible format (e.g., in the form of an information element). The application layer indicators may include the RAN-device-detectable application layer indicators of step 201 above, or may include a comprehensive score of the application layer indicators, a comprehensive score of the access layer indicators, a comprehensive score obtained by combining the application layer indicators and the access layer indicators, or an indicator indicating the quality of the application layer indicators (e.g., the value may be good, medium, or poor). For example, the RAN device may deliver some thresholds to the UE, and the UE knows the quality indicators corresponding to the reported application layer indicator measurement results based on the application layer indicator measurement results and the thresholds corresponding to the application layer measurement indicators. The RAN device may further configure a reporting period for the UE to report the RAN-device-visible application layer indicators. When the RAN device does not configure a reporting period, the UE may report the RAN-visible application layer indicators when reporting measurement results corresponding to the application layer measurement configuration. In addition, the RAN device may not need to deliver some configuration information to the UE for reporting the application layer indicators detected by the RAN device. After the UE acquires the application layer indicators, the UE reports some protocol-specified application layer indicators that can currently be acquired by the UE to the RAN device.

[0119] Optionally, in addition to sending the application layer measurement configuration to the UE, the RAN device may also deliver application layer measurement identifiers to the UE. The application layer measurement identifiers are generated by the RAN device for the UE, and one application layer measurement identifier corresponds to one application layer measurement configuration configured by the RAN device for the UE, i.e., one application layer measurement identifier corresponds to one QoE task. Typically, the application layer measurement identifier corresponds to a QoE reference. The RAN device stores the correspondence between the application layer measurement identifier and the QoE reference.

[0120] Optionally, the RAN device may send the application layer measurement configuration and the RAN visible measurement configuration to the UE using the same RRC message, or may send the application layer measurement configuration and the RAN visible measurement configuration to the UE using different RRC information, for example, the RAN device first sends the application layer measurement configuration to the UE and then sends the RAN visible application layer measurement configuration to the UE, or the RAN device first sends the RAN visible application layer measurement configuration to the UE and then sends the application layer measurement configuration to the UE.

[0121] 203: The UE performs a QoE measurement task.

[0122] After receiving the application layer measurement configuration and the corresponding service type from the RAN device, the access stratum (AS) of the UE sends the application layer measurement configuration and the corresponding service type from the RAN device to an upper layer of the AS layer of the UE, and the upper layer of the AS layer of the UE performs a corresponding QoE measurement task. After completing the QoE measurement task, the UE obtains the measurement result corresponding to the QoE measurement task. The upper layer of the AS of the UE may be an application layer or a layer for performing QoE measurement.

[0123] In addition to sending the application layer measurement configuration to the upper layer of the AS, the AS of the UE may further send configuration information of some application layer indicators received from the RAN device to the upper layer of the AS of the UE, indicating to the UE to report in a RAN detectable format.

[0124] 204: The UE sends the measurement result corresponding to the QoE measurement task to the RAN device.

[0125] The UE transmits measurement results corresponding to the QoE measurement task to the RAN device. For example, the measurement results may be carried in an uplink RRC message to reach the RAN device. In practical application, the measurement results may be transmitted to the RAN device in a container encapsulated format or a non-container encapsulated format. In addition to reporting the measurement results, the UE may also report an application layer measurement identifier corresponding to the measurement results.

[0126] 205: The RAN device sends the measurement result corresponding to the QoE measurement task to the MCE.

[0127] After the UE reports the measurement result corresponding to the QoE measurement task to the RAN device, the RAN device transmits the measurement result to the MCE. For example, when transmitting the measurement result to the RAN device, the UE carries an application layer measurement identifier corresponding to the measurement result. Therefore, the RAN device determines the QoE reference corresponding to the measurement result and the application layer measurement identifier reported by the UE based on the locally stored correspondence between the application layer measurement identifier and the QoE reference. Then, the RAN device finds the IP address of the corresponding MCE based on the QoE reference and transmits the measurement result to the MCE. In another example, the RAN device obtains the corresponding application layer measurement configuration based on the UE's application layer measurement identifier, and then obtains the IP address of the MCE corresponding to the measurement result based on the QoE measurement collection configuration information delivered by the CN, the OAM entity, or the EM entity to transmit the measurement result to the MCE.

[0128] Additionally, the RAN device may optimize radio resources based on the RAN visible measurements reported by the UE. For example, when the RAN device detects that the value of a particular application layer indicator in the RAN visible measurements is not ideal, the RAN device may allocate more resources to the UE, or may increase the scheduling priority of the UE's resources, etc.

[0129] Optionally, when the CN, the OAM entity, or the EM entity notifies the RAN device that the MDT measurement result needs to be associated with the measurement result of the QoE measurement task, the CN, the OAM entity, or the EM entity sends to the RAN device indication information indicating that the MDT is associated with QoE. The RAN device configures MDT measurements for the UE (this may be before, after, or simultaneously with configuring the application layer measurements). After the RAN device receives the MDT measurement results sent by the UE or after the RAN device obtains the MDT measurement results through autonomous measurement, the RAN device sends the MDT measurement results to the TCE, and when sending the measurement results of the QoE measurement task to the MCE, the RAN device carries an MDT measurement identifier. Then, the MCE or the TCE finds the MDT measurement results associated with the measurement results of the QoE measurement task based on the measurement results of the QoE measurement task and the MDT measurement identifier associated with the QoE measurement task, and obtains an association relationship between the measurement results of the QoE measurement task and the MDT measurement results.

[0130] Steps 201 to 205 are a QoE measurement method when the RAN device is an NR base station in an NR network. However, in an LTE network, one UE can only simultaneously perform one QoE measurement task via an LTE base station. Therefore, when configuring a QoE measurement task for the UE, the LTE base station does not need to carry an application layer measurement identifier, and when reporting the QoE measurement result, the UE does not need to carry an application layer measurement identifier.

[0131] In practical application, in the process of a UE performing a QoE measurement task, a cell handover may occur, i.e., the UE may be handed over to a currently accessed RAN device. Therefore, when the UE hands over to a RAN device to which the UE is connected in the process of performing a QoE measurement task, the RAN device that delivers the application layer measurement configuration information and the RAN device that receives the measurement results may be different RAN devices. When the UE does not hand over to a RAN device to which the UE is connected in the process of performing a QoE measurement task, the RAN device that delivers the application layer measurement configuration information and the RAN device that receives the measurement results are usually the same RAN device.

[0132] Therefore, in the process of a UE performing a QoE measurement task configured by an NR base station, when a radio access network (RAN) device accessed by the UE is handed over from a new radio (NR) base station to a long term evolution (LTE) base station, the measurement results subsequently reported by the UE are reported to the LTE base station, not to the NR base station. In practical application, the LTE base station may be connected to a 4G core network, for example, an evolved packet core network (EPC), or a 5G core network, for example, a fifth generation core network (5GC). This is not a limitation in this application.

[0133] Currently, all the characteristics of the QoE measurement task in an NR base station can be introduced into an LTE base station by modifying the protocol standard on which the LTE base station operates to implement continuity of the QoE measurement task during handover of a UE from an NR base station to an LTE base station. For example, an NR base station supports simultaneous execution of multiple QoE measurement tasks for a UE, while an LTE base station supports execution of only one QoE measurement task for a UE at a time. Therefore, when a RAN device accessed by a UE is handed over from an NR base station to an LTE base station, the protocol standard on which the LTE base station operates needs to be modified to enable the LTE base station to simultaneously execute multiple QoE measurement tasks for the UE and implement continuity of the QoE measurement task, which increases the difficulty and complexity of implementation.

[0134] In another aspect, after a RAN device accessed by a UE is handed over from an NR base station to an LTE base station, the QoE measurement task performed by the UE in the LTE network is no longer associated with the MDT task in the NR network, thereby affecting the efficiency of the problem of identifying services.

[0135] In consideration of this, the present application provides a quality of experience measurement method, a communication apparatus, and a communication device to improve the efficiency of QoE measurement. Figure 3 is a schematic flowchart of the quality of experience measurement method according to the present application. In Figure 3, an example is used in which RAN devices (including a first RAN device and a second RAN device) and a UE are used as the execution body of an interaction diagram to illustrate the method. However, the execution body of the interaction diagram is not limited in the present application. For example, the RAN device in Figure 3 may alternatively be a chip, chip system, or processor supporting the RAN device to implement the method, or may be a logical node, logical module, or software capable of implementing all or part of the base station functions. The UE in Figure 3 may alternatively be a chip, chip system, or processor supporting the UE to implement the method, or may be a logical node, logical module, or software capable of implementing all or part of the terminal functions. As shown in Figure 3, the quality of experience measurement method in the present application includes the following steps:

[0136] 301: A first RAN device sends a handover request for a UE to a second RAN device.

[0137] The first RAN device sends a handover request for the UE to the second RAN device to notify the second RAN device that the UE needs to access the second RAN device. In this application, the first RAN device and the second RAN device are RAN devices in different networks. The first RAN device can adapt to the QoE measurement task configured by the second RAN device, i.e., the QoE measurement task configured by the second RAN device for the UE can continue to be performed by the first RAN device. However, the second RAN device cannot fully and completely adapt to the QoE measurement task configured by the first RAN device, i.e., the QoE measurement task configured by the first RAN device for the UE cannot continue to be fully and completely performed by the second RAN device. For example, in actual application, the first RAN device may be an NR base station, and the second RAN device may be an LTE base station.

[0138] The UE accesses the first RAN device, and the first RAN device configures a QoE measurement task for the UE. There may be one or more QoE measurement tasks configured by the first RAN device for the UE. This is not limited in the present application. The QoE measurement procedure may be first initiated by the core network, an OAM entity, or an EM entity, and the first RAN device configures a corresponding QoE measurement task for the UE, and then the UE executes the QoE measurement task. Alternatively, the first RAN device may trigger a QoE measurement task by itself and configure a corresponding QoE measurement task for the UE, and then the UE executes the QoE measurement task. Specifically, for a description of configuring a QoE measurement task for the UE by the first RAN device, please refer to the contents of steps 201 to 203 corresponding to FIG. 2. Details will not be described again here.

[0139] In a possible embodiment, the handover request sent by the first RAN device to the second RAN device may indicate at least one of a first QoE measurement task, a second QoE measurement task, or a third QoE measurement task, where the first QoE measurement task is a QoE measurement task that the UE continues to execute and continue to report measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE continues to report measurement results), the second QoE measurement task is a QoE measurement task that the UE continues to execute and suspends reporting measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE suspends reporting measurement results), and the third QoE measurement task is a QoE measurement task whose execution is canceled by the UE after the UE accesses the second RAN device. In other words, the first RAN device determines and selects a specific QoE measurement task among the QoE measurement tasks configured by the first RAN device for the UE as the first QoE measurement task, the second QoE measurement task, or the third QoE measurement task. Thus, using the handover request from the first RAN device, the second RAN device can determine, among the QoE measurement tasks configured by the first RAN device for the UE, specific QoE measurement tasks that the UE will continue to execute and continue reporting measurement results for after being handed over to the second RAN device, specific QoE measurement tasks that the UE will continue to execute and suspend reporting measurement results for after being handed over to the second RAN device, and specific QoE measurement tasks whose execution will be canceled after the UE is handed over to the second RAN device. For example, the handover request sent by the first RAN device to the second RAN device instructs the UE to keep reporting measurement results for only one QoE measurement task for a streaming service or an MTSI service after the UE accesses the second RAN device.

[0140] Optionally, the handover request sent by the first RAN device to the second RAN device for the UE includes a QoE reference and an address of an MCE corresponding to each QoE measurement task, which are obtained by the first RAN device from a core network, an OAM entity, or an EM entity. Optionally, the handover request further includes an application layer measurement configuration and an application layer measurement identifier corresponding to each QoE measurement task.

[0141] 302: The second RAN device sends a handover acknowledgement message to the first RAN device.

[0142] After receiving the handover request, the second RAN device is authorized to provide access handover services to the UE and sends a handover acknowledgement message to the first RAN device in response to the handover request.

[0143] In a possible embodiment, the handover acknowledgement message sent by the second RAN device to the first RAN device may indicate at least one of a first QoE measurement task, a second QoE measurement task, or a third QoE measurement task, where the first QoE measurement task is a QoE measurement task that the UE continues to execute and continue to report measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE continues to report measurement results), the second QoE measurement task is a QoE measurement task that the UE continues to execute and suspends reporting measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE suspends reporting measurement results), and the third QoE measurement task is a QoE measurement task whose execution is canceled by the UE after the UE accesses the second RAN device. Typically, the second RAN device explicitly indicates at least one of the first QoE measurement task, the second QoE measurement task, or the third QoE measurement task in an interface message between the first RAN device and the second RAN device, i.e., the first RAN device can detect the indication.

[0144] In other words, the second RAN device determines and selects a specific QoE measurement task among the QoE measurement tasks configured by the first RAN device for the UE as the first QoE measurement task, the second QoE measurement task, or the third QoE measurement task. Thus, using the handover acknowledgement message from the second RAN device, the first RAN device may determine, among the QoE measurement tasks configured by the first RAN device for the UE, specific QoE measurement tasks that the UE will continue to execute and continue reporting measurement results for after being handed over to the second RAN device, specific QoE measurement tasks that the UE will continue to execute and suspend reporting measurement results for after being handed over to the second RAN device, and specific QoE measurement tasks whose execution will be canceled after the UE is handed over to the second RAN device. For example, the handover acknowledgement message sent by the second RAN device to the first RAN device indicates to the UE to keep reporting the measurement results of only one QoE measurement task in a streaming service or an MTSI service after the UE accesses the second RAN device.

[0145] It can be seen from the foregoing that in the present application, a particular QoE measurement task among the QoE measurement tasks configured by the first RAN device for the UE may be determined and selected by the first RAN device or may be determined and selected by the second RAN device as the first QoE measurement task, the second QoE measurement task, or the third QoE measurement task.

[0146] In practical application, the handover acknowledgement message further carries an RRC message configured by the second RAN device for the UE. The RRC message carries a target cell identifier and radio parameter information configured by the second RAN device for the UE. The RRC message is carried in the form of a container, that is, the first RAN device does not need to know the specific meaning of the content carried in the container.

[0147] 303: The first RAN device sends an access handover command to the UE, where the access handover command indicates a target QoE measurement task.

[0148] For example, in practical application, the access handover command may be an RRC message generated by the first RAN device, and the RRC message may carry configuration information generated by the first RAN device and an RRC message (carried in the form of a container) configured by the second RAN device for the UE.

[0149] The target QoE measurement task is a QoE measurement task that continues to execute after the UE accesses the second RAN device. In the present application, the first RAN device and the second RAN device may determine, in the QoE measurement task configured by the first RAN device for the UE, a specific QoE measurement task belonging to the target QoE measurement task, i.e., a specific QoE measurement task that may continue to execute after the UE accesses the second RAN device. Therefore, after determining and selecting the target QoE measurement task, the first RAN device or the second RAN device indicates the target QoE measurement task using an access handover command. Specifically, the access handover command includes first instruction information, which indicates at least one of a first QoE measurement task, a second QoE measurement task, or a third QoE measurement task, where the first QoE measurement task is a QoE measurement task that the UE continues to execute and continues to report measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE continues to report measurement results), the second QoE measurement task is a QoE measurement task that the UE continues to execute and suspends reporting measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE suspends reporting measurement results), and the third QoE measurement task is a QoE measurement task whose execution is canceled by the UE after the UE accesses the second RAN device. The UE only needs to determine the target QoE measurement task based on the instruction of the access handover command, thereby improving the efficiency of performing QoE measurements by the UE and reducing the computational load on the UE. For example, the first indication information is part of the configuration information generated by the first access network device in the access handover command, and is not included in the RRC message configured by the second RAN device for the UE.

[0150] For example, the first instruction information may include an application layer measurement identifier corresponding to the target QoE measurement task, or the first instruction information may include an application layer measurement identifier corresponding to the QoE measurement task whose execution is to be canceled, in which case the UE may obtain the application layer measurement identifier corresponding to the QoE measurement task whose execution is to be canceled and determine that the remaining QoE measurement tasks whose execution is to be canceled, other than the QoE measurement task whose execution needs to be canceled among the QoE measurement tasks configured by the first RAN device for the UE, are target QoE measurement tasks, or the first instruction information may include an application layer measurement identifier corresponding to the target QoE measurement task and an application layer measurement identifier corresponding to the QoE measurement task whose execution is to be canceled.

[0151] In a possible embodiment, the access handover command includes third instruction information, which indicates to the UE to cancel reporting of RAN device visible measurement results. In a scenario where the first RAN device is an NR base station and the second RAN device is an LTE base station, the LTE base station cannot detect the RAN device visible measurement results. As a result, it is meaningless to report the RAN device visible measurement results to the second RAN device, and the third instruction information may indicate to the UE to cancel reporting of the RAN device visible measurement results, thereby reducing the operational load of the UE and improving the efficiency of performing QoE measurements by the UE. In another aspect, the third instruction information may further indicate to the UE to cancel performing a RAN visible measurement task. For example, the third instruction information is part of configuration information generated by the first access network device in the access handover command and is not included in an RRC message configured by the second RAN device for the UE.

[0152] 304: After accessing the second RAN device, the UE continues to perform the target QoE measurement task based on the instruction of the access handover command.

[0153] After receiving the handover command, the UE is handed over to the second RAN device. Since the handover command indicates a target QoE measurement task, after accessing the second RAN device, the UE continues to perform the target QoE measurement task indicated by the access handover command. The above is an indication indicating the AS of the UE receiving the handover command from the first RAN device. For the third QoE measurement task, the AS of the UE sends indication information to the upper layer of the AS of the UE to indicate that the third QoE measurement task should be canceled.

[0154] For the second QoE measurement task, when the UE generates a measurement result for the second QoE measurement task, the UE may store the measurement result in an upper layer of the AS of the UE or in the AS of the UE.

[0155] In the present application, after a UE is handed over from a first RAN device to a second RAN device, the UE may select a target QoE measurement task to continue to be executed from the QoE measurement task configured by the first RAN device for the UE. Since the target QoE measurement task is a QoE measurement task that satisfies the protocol standard under which the second RAN device operates, the protocol standard under which the second RAN device operates does not need to be modified, thereby implementing the continuity of the QoE measurement and also improving the efficiency of the QoE measurement task.

[0156] 305: The UE sends the measurement result of the target QoE measurement task to the second RAN device.

[0157] The target QoE measurement task may be divided into a first QoE measurement task and a second QoE measurement task, where the first QoE measurement task is a QoE measurement task that the UE continues to execute and continues to report measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE continues to report measurement results), and the second QoE measurement task is a QoE measurement task that the UE continues to execute and suspends reporting measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE suspends reporting measurement results). Thus, when executing the first QoE measurement task of the target QoE measurement task, the UE may generate measurement results and transmit the measurement results corresponding to the target QoE measurement task (first QoE measurement task) to the second RAN device.

[0158] Optionally, when the first QoE measurement task includes only one QoE measurement task and the UE transmits the measurement result corresponding to the first QoE measurement task to the second RAN device, the UE does not need to transmit an application layer measurement identifier corresponding to the first QoE measurement task to the second RAN device. After the second RAN device receives the measurement result transmitted by the UE, the second RAN device can know the specific measurement task that is the UE's first QoE measurement task (e.g., selected based on the determination of the first RAN device or the determination of the second RAN device described above), and therefore the second RAN device can still know the QoE reference corresponding to the first QoE measurement task and the address of the MCE, so that the second RAN device transmits the measurement result corresponding to the first QoE measurement task to the MCE. Optionally, the second RAN device further transmits the QoE reference corresponding to the first QoE measurement task to the MCE.

[0159] In practical application, the measurement results of the QoE measurement task received by the first RAN device and the second RAN device need to be reported to a QoE measurement collection device (i.e., MCE). In a possible embodiment, the QoE measurement collection devices corresponding to the first RAN device and the second RAN device may be the same or different. When the first RAN device sends a handover request to the second RAN device, the handover request includes the address of the first QoE measurement collection device and the address of the second QoE measurement collection device. Regarding the addresses of the first QoE measurement collection device and the second QoE measurement collection device in the first RAN device, the CN, the OAM entity, or the EM entity includes the addresses of the first QoE measurement collection device and the second QoE measurement collection device in QoE measurement collection configuration information when initiating QoE measurement, and sends the configuration information to the first RAN device. The first QoE measurement collection device is configured to collect measurement results of the QoE measurement task from the first RAN device, and the second QoE measurement collection device is configured to collect measurement results of the QoE measurement task from the second RAN device. Thus, after the UE is handed over to the second RAN device, the second RAN device receives the measurement results of the target QoE measurement task reported by the UE, and the second RAN device sends the measurement results of the target QoE measurement task (e.g., the measurement results carried in the form of a container) to the second QoE measurement collection device based on the address of the second QoE measurement collection device. The QoE measurement collection device corresponding to the first RAN device and the QoE measurement collection device corresponding to the second RAN device are distinguished, thereby improving the management efficiency of the measurement results of the QoE measurement task.

[0160] In a possible embodiment, when the UE is handed over to a third RAN device again after accessing the second RAN device, the UE may send a QoE measurement record to the third RAN device, where the QoE measurement record indicates at least one of a first QoE measurement task, a second QoE measurement task, or a third QoE measurement task, and the QoE measurement record is used so that the third RAN device can determine the execution of the QoE measurement task configured by the first RAN device for the UE to perform subsequent processing on the QoE measurement task configured by the first RAN device for the UE, thereby improving the efficiency of QoE measurement. In practical application, the third RAN device may be an NR base station or an LTE base station. For example, if the second RAN device is an LTE base station and the third RAN device is an NR base station, the third RAN device may indicate to the UE to resume reporting of measurement results of a QoE measurement task that continues to be executed but for which reporting of the measurement results has been paused, or may indicate to the UE to re-execute a QoE measurement task whose execution has been canceled and report the corresponding measurement results.

[0161] In a possible embodiment, when the UE is handed over again to a third RAN device after accessing the second RAN device, the second RAN device may send a QoE measurement record to the third RAN device, where the QoE measurement record indicates at least one of the first QoE measurement task, the second QoE measurement task, or the third QoE measurement task.

[0162] In a possible embodiment, when the UE is handed over to the third RAN device again after accessing the second RAN device, for the second QoE measurement task, if the UE stores the measurement result of the second QoE measurement task, the UE sends indication information to the third RAN device to indicate that the UE has the measurement result of the second QoE measurement task. The description of the third RAN device is the same as that provided above.

[0163] It should be noted that in step 305, it is optional for the UE to send the measurement result of the target QoE measurement task to the second RAN device.

[0164] FIG. 4 is another schematic flowchart of a quality of experience measurement method according to the present application. In FIG. 4, an example is used in which RAN devices (including a first RAN device and a second RAN device) and a UE are used as the execution body of an interaction diagram to illustrate the present method. However, the execution body of the interaction diagram is not limited in the present application. For example, the RAN device in FIG. 4 may alternatively be a chip, chip system, or processor supporting the RAN device to implement the present method, or may be a logical node, logical module, or software capable of implementing all or part of the base station functions. The UE in FIG. 4 may alternatively be a chip, chip system, or processor supporting the UE to implement the present method, or may be a logical node, logical module, or software capable of implementing all or part of the terminal functions. As shown in FIG. 4, the quality of experience measurement method in the present application includes the following steps:

[0165] 401: A first RAN device sends a handover request for a UE to a second RAN device.

[0166] In this application, the first RAN device and the second RAN device are RAN devices in different networks. The first RAN device can adapt to the QoE measurement task configured by the second RAN device, i.e., the QoE measurement task configured by the second RAN device for the UE can continue to be performed by the first RAN device. However, the second RAN device cannot fully and completely adapt to the QoE measurement task configured by the first RAN device, i.e., the QoE measurement task configured by the first RAN device for the UE cannot continue to be fully and completely performed by the first RAN device. For example, in actual application, the first RAN device may be an NR base station, and the second RAN device may be an LTE base station.

[0167] The UE accesses the first RAN device, and the first RAN device configures a QoE measurement task for the UE. There may be one or more QoE measurement tasks configured by the first RAN device for the UE. This is not limited in the present application. The QoE measurement procedure may be first initiated by the core network, an OAM entity, or an EM entity, and the first RAN device configures a corresponding QoE measurement task for the UE, and then the UE executes the QoE measurement task. Alternatively, the first RAN device may trigger a QoE measurement task by itself and configure a corresponding QoE measurement task for the UE, and then the UE executes the QoE measurement task. Specifically, for a description of configuring a QoE measurement task for the UE by the first RAN device, please refer to the contents of steps 201 to 203 corresponding to FIG. 2. Details will not be described again here.

[0168] 402: The second RAN device sends a handover acknowledgement message to the first RAN device.

[0169] After receiving the handover request, the second RAN device is authorized to provide access handover services to the UE and sends a handover acknowledgement message to the first RAN device in response to the handover request. In practice, the handover acknowledgement message further carries an RRC message configured by the second RAN device for the UE. The RRC message carries a target cell identifier and radio parameter information configured by the second RAN device for the UE. The RRC message is carried in the form of a container.

[0170] 403: The first RAN device sends an access handover command to the UE.

[0171] After receiving the access handover command from the first RAN device, the UE accesses the second RAN device based on the access handover command.

[0172] 404: The UE determines a target QoE measurement task based on the access handover command.

[0173] In the present application, after receiving an access handover command, the UE may autonomously determine a target QoE measurement task that needs to continue to be executed in the QoE measurement task configured by the first RAN device for the UE.

[0174] In a possible embodiment, the first RAN device may include second instruction information in the access handover command, where the second instruction information indicates a third QoE measurement task, the execution of which is to be canceled by the UE after the UE accesses the second RAN device. Thus, the UE knows which QoE measurement task (i.e., the third QoE measurement task) needs to be canceled among the QoE measurement tasks configured for the UE by the first RAN device. Specifically, after the UE accesses the second RAN device or after the UE receives the access handover command, the UE may detect a QoE measurement task that is not supported by the second RAN device using a communication protocol between the UE and the second RAN device. Thus, the UE may determine, as a target QoE measurement task, a QoE measurement task that can be supported by the second RAN device, other than the third QoE measurement task, among the QoE measurement tasks configured for the UE by the first RAN device. The UE autonomously determines the target QoE measurement task so that the amount of information exchange between the first RAN device and the second RAN device is reduced and the handover efficiency of the UE to the RAN device is improved. For example, the third indication information is part of the configuration information generated by the first access network device in the access handover command, and is not included in the RRC message configured by the second RAN device for the UE.

[0175] For example, assuming a scenario where the first RAN device is an NR base station and the second RAN device is an LTE base station, in addition to the third QoE measurement task indicated by the second indication information carried in the access handover command, the QoE measurement tasks configured by the first RAN device for the UE further include a QoE measurement task for a streaming service, a QoE measurement task for an MTSI service, and a QoE measurement task for a virtual reality (VR) service. Since the UE knows that in an LTE network, the LTE base station does not support the QoE measurement task for the VR service, the UE may determine the QoE measurement task for the streaming service and the QoE measurement task for the MTSI service as target QoE measurement tasks.

[0176] In a possible embodiment, the access handover command sent to the UE by the first RAN device does not carry the second indication information. After the UE accesses the second RAN device or receives the access handover command, the UE may detect QoE measurement tasks that are not supported by the second RAN device using a communication protocol between the UE and the second RAN device. Therefore, the UE may determine, as a target QoE measurement task, a QoE measurement task that can be supported by the second RAN device among the QoE measurement tasks configured for the UE by the first RAN device. The first RAN device does not need to modify or extend a conventional access handover command. The UE accesses the second RAN device using an existing RAN device handover method, and then the UE autonomously determines the target QoE measurement task. This reduces the amount of information exchange between the first RAN device and the second RAN device and improves the efficiency of UE handover to the RAN device.

[0177] In a scenario where the first RAN device is an NR base station and the second RAN device is an LTE base station, the LTE base station can simultaneously support only one QoE measurement task for one UE and report the measurement results of the QoE measurement task. In a possible embodiment, when there is one target QoE measurement task determined by the UE and the target QoE measurement task can be accurately supported by the second RAN device used as an LTE base station, the UE may continue to report the measurement results of the target QoE measurement task, i.e., the target QoE measurement task is the first QoE measurement task in this application.

[0178] In a possible embodiment, when there are multiple target QoE measurement tasks determined by the UE and these target QoE measurement tasks cannot be simultaneously supported by the second RAN device used as an LTE base station, the UE may suspend reporting the measurement results of all target QoE measurement tasks, i.e., these target QoE measurement tasks are second QoE measurement tasks in this application.

[0179] For example, if the target QoE measurement task includes only one QoE measurement task of a streaming service, the second RAN device can support the QoE measurement task of the streaming service, so the UE continues to report the measurement results of the QoE measurement task of the streaming service; or if the target QoE measurement task includes one QoE measurement task of a streaming service and one QoE measurement task of an MTSI service, the UE suspends reporting the measurement results of the two target QoE measurement tasks.

[0180] In a possible embodiment, the access handover command sent to the UE by the first RAN device does not carry the second indication information. After the UE accesses the second RAN device or after the UE receives the access handover command, the UE stores all QoE measurement tasks configured for the UE by the first RAN device and suspends reporting of the measurement results of all these QoE measurement tasks. That is, all QoE measurement tasks configured for the UE by the first RAN device are target QoE measurement tasks. In addition, all target QoE measurement tasks are second QoE measurement tasks. The second QoE measurement tasks are QoE measurement tasks that the UE continues to execute and suspends reporting of the measurement results after accessing the second RAN device (i.e., target QoE measurement tasks for which the UE suspends reporting of the measurement results). Therefore, after accessing the second RAN device, the UE continues to execute all QoE measurement tasks and may report the QoE measurement results when the QoE measurement results can be reported later.

[0181] In a possible embodiment, the access handover command sent by the first RAN device to the UE carries second instruction information. After the UE accesses the second RAN device or after the UE receives the access handover command, the UE stores all QoE measurement tasks configured by the first RAN device for the UE except for the third QoE measurement task indicated by the second instruction information, and suspends reporting of the measurement results of all these QoE measurement tasks. That is, all QoE measurement tasks configured by the first RAN device for the UE except for the third QoE measurement task are target QoE measurement tasks. In addition, all target QoE measurement tasks are second QoE measurement tasks. The second QoE measurement task is a QoE measurement task that the UE continues to execute and suspends reporting of the measurement results after accessing the second RAN device (i.e., a target QoE measurement task for which the UE suspends reporting of the measurement results). Therefore, after accessing the second RAN device, the UE may continue to perform all target QoE measurement tasks and report the QoE measurement results when they can be reported later.

[0182] 405: The UE continues to perform the target QoE measurement task.

[0183] 406: The UE sends the measurement result of the target QoE measurement task to the second RAN device.

[0184] The implementation of step 406 is similar to the implementation of step 305 corresponding to Fig. 3. For details, please refer to the description of step 305. The details will not be described again here.

[0185] Optionally, when the first QoE measurement task includes only one QoE measurement task and the UE transmits the measurement result corresponding to the first QoE measurement task to the second RAN device, the UE does not need to transmit the application layer measurement identifier corresponding to the first QoE measurement task to the second RAN device. After the second RAN device receives the measurement result transmitted by the UE, the second RAN device can know which specific measurement task is the UE's first QoE measurement task (e.g., the second base station and the UE may use the same rule to determine which specific QoE measurement task is the first QoE measurement task), so the second RAN device can still know the QoE reference and the address of the MCE corresponding to the first QoE measurement task, thereby transmitting the measurement result corresponding to the first QoE measurement task to the MCE. Optionally, the second RAN device further transmits the QoE reference corresponding to the first QoE measurement task to the MCE.

[0186] FIG. 5 is another schematic flowchart of a quality of experience measurement method according to the present application. In FIG. 5, an example is used in which RAN devices (including a first RAN device and a second RAN device) and a UE are used as the execution body of an interaction diagram to illustrate the present method. However, the execution body of the interaction diagram is not limited in the present application. For example, the RAN device in FIG. 5 may alternatively be a chip, chip system, or processor supporting the RAN device to implement the present method, or may be a logical node, logical module, or software capable of implementing all or part of the base station functions. The UE in FIG. 5 may alternatively be a chip, chip system, or processor supporting the UE to implement the present method, or may be a logical node, logical module, or software capable of implementing all or part of the terminal functions. As shown in FIG. 5, the quality of experience measurement method in the present application includes the following steps:

[0187] 501: A first RAN device sends a handover request to a second RAN device.

[0188] Optionally, before step 501, for a description of configuring a QoE measurement task for the UE by the first RAN device, please refer to the contents of steps 201 to 203 corresponding to Figure 2. The details will not be described again here. If the association between the MDT and the QoE measurement needs to be performed for a specific QoE measurement task, the first RAN device also initiates an MDT task corresponding to the QoE measurement.

[0189] The first RAN device sends a handover request to the second RAN device, where the handover request includes fourth indication information, where the fourth indication information indicates a first MDT task and a second MDT task associated with the same QoE measurement task, where the first MDT task is an MDT task associated with the QoE measurement task when the UE accesses the first RAN device, and the second MDT task is an MDT task associated with the QoE measurement task when the UE accesses the second RAN device. For example, the fourth indication information is an MDT task identifier of the first MDT task and an MDT task identifier of the second MDT task. The first MDT task is an MDT task associated with the QoE measurement task when the UE accesses the first RAN device. In other words, the first MDT task is an MDT task associated with the QoE measurement task when the UE accesses a RAN device of the same type as the first RAN device (including the first RAN device). For example, the first MDT task is an MDT task associated with a QoE measurement task when the UE accesses an NR base station. Similarly, the second MDT task is an MDT task associated with a QoE measurement task when the UE accesses a second RAN device. In other words, the second MDT task is an MDT task associated with a QoE measurement task when the UE accesses a RAN device of the same type as the second RAN device (including the second RAN device). For example, the second MDT task is an MDT task associated with a QoE measurement task when the UE accesses an LTE base station. Note that in the above description, the first MDT task and the second MDT task being associated with the same QoE measurement task only means that some QoE measurement tasks need to be associated with the MDT, but does not mean that all QoE measurement tasks sent by the first RAN device to the second RAN device need to be associated with the MDT. That is, the fourth indication information is for a specific QoE measurement task.

[0190] The fourth indication information of the first RAN device is obtained by the CN, the OAM entity, or the EM entity. Specifically, the CN, the OAM entity, or the EM entity may carry the fourth indication information when sending the QoE measurement collection configuration information to the first RAN device.

[0191] 502: The second RAN device sends a handover acknowledgement message to the first RAN device.

[0192] After receiving the handover request, the second RAN device is authorized to provide access handover services to the UE and sends a handover acknowledgement message to the first RAN device in response to the handover request.

[0193] 503: The first RAN device sends an access handover command to the UE.

[0194] The first RAN device sends an access handover command to the UE to indicate that the UE is handed over to the second RAN device. Specifically, the process of handing over the UE from the first RAN device to the second RAN device may be a conventional procedure in which the UE is handed over to a RAN device, or may be a procedure in which the UE is handed over to the second RAN device in an embodiment corresponding to Figure 3 of the present application (for details, see steps 301 to 304) to continue performing the target QoE measurement task, or may be a procedure in which the UE is handed over to the second RAN device in an embodiment corresponding to Figure 4 of the present application (for details, see steps 401 to 405) to continue performing the target QoE measurement task.

[0195] In practical application, the access handover command further carries configuration information of a second MDT task configured by the second RAN device for the UE. After accessing the second RAN device, the UE executes the MDT task based on the configuration information of the second MDT task.

[0196] The following uses an example in which the UE determines the target QoE measurement task for illustration.

[0197] 504: The UE sends the measurement result of the target QoE measurement task to the second RAN device.

[0198] The measurement result of the target QoE measurement task sent by the UE to the second RAN device may carry an application layer measurement identifier corresponding to the target QoE measurement task. After receiving the measurement result of the target QoE measurement task and the application layer measurement identifier corresponding to the target QoE measurement task, the second RAN device may determine the specific QoE measurement task to which the measurement result belongs. Because the fourth indication information indicates the first MDT task and the second MDT task associated with each QoE measurement task, the second RAN device can determine the second MDT task corresponding to the target QoE measurement task based on the fourth indication information. In this way, even after the UE is handed over from the first RAN device to the second RAN device, the QoE measurement task is still associated with the MDT task. This simplifies the problem of continuing to identify services.

[0199] 505: The second RAN device sends the measurement result of the target QoE measurement task to the MCE.

[0200] The second RAN device transmits to the MCE the measurement result of the target QoE measurement task and an identifier (e.g., a trace ID) of the second MDT task associated with the target QoE measurement task. Optionally, the second RAN device further transmits a QoE reference of the target QoE measurement task.

[0201] FIG. 6 is another schematic flowchart of a quality of experience measurement method according to the present application. In FIG. 6, an example is used in which RAN devices (including a first RAN device and a second RAN device) and a UE are used as the execution body of an interaction diagram to illustrate the present method. However, the execution body of the interaction diagram is not limited in the present application. For example, the RAN device in FIG. 6 may alternatively be a chip, chip system, or processor supporting the RAN device to implement the present method, or may be a logical node, logical module, or software capable of implementing all or part of the base station functions. The UE in FIG. 6 may alternatively be a chip, chip system, or processor supporting the UE to implement the present method, or may be a logical node, logical module, or software capable of implementing all or part of the terminal functions. As shown in FIG. 6, the quality of experience measurement method in the present application includes the following steps:

[0202] 601: A first RAN device sends a handover request to a second RAN device.

[0203] Optionally, before step 601, for a description of configuring a QoE measurement task for the UE by the first RAN device, please refer to the contents of steps 201 to 203 corresponding to Figure 2. The details will not be described again here. If the association between the MDT and the QoE measurement needs to be performed for a specific QoE measurement task, the first RAN device also initiates an MDT task corresponding to the QoE measurement.

[0204] Optionally, the handover request includes indication information #A, where the indication information #A indicates a first MDT task associated with the QoE measurement task. For example, the indication information #A is an MDT task identifier of the first MDT task. The first MDT task is an MDT task associated with the QoE measurement task when the UE accesses the first RAN device.

[0205] 602: The second RAN device sends a handover acknowledgement message to the first RAN device.

[0206] After receiving the handover request, the second RAN device is authorized to provide access handover services to the UE and sends a handover acknowledgement message to the first RAN device in response to the handover request.

[0207] 603: The first RAN device sends an access handover command to the UE.

[0208] Step 602 and step 603 are similar to the implementation of step 502 and step 503 corresponding to Fig. 5. For details, please refer to the description of step 502 and step 503. The details will not be described again here.

[0209] 604: The second RAN device obtains fifth indication information.

[0210] The second RAN device obtains fifth indication information, where the fifth indication information indicates a second MDT task associated with the target QoE measurement task. Specifically, the second RAN device may first send a QoE reference corresponding to the target QoE measurement task to the CN, the OAM entity, or the EM entity. In this case, the CN, the OAM entity, or the EM entity sends fifth indication information to the second RAN device based on the QoE reference, where the fifth indication information indicates the second MDT task associated with the target QoE measurement task. The second MDT task is an MDT task associated with the QoE measurement task when the UE accesses the second RAN device. For example, the second RAN device knows that the target QoE measurement task needs to be associated with an MDT task based on indication information #A carried in the handover request in step 601. Therefore, the second RAN device sends a QoE reference corresponding to the target QoE measurement task to the CN, the OAM entity, or the EM entity. In this case, the CN, the OAM entity, or the EM entity sends fifth indication information to the second RAN device based on the QoE reference.

[0211] 605: The UE sends the measurement result of the target QoE measurement task to the second RAN device.

[0212] 606: The second RAN device sends the measurement result of the target QoE measurement task to the MCE.

[0213] Step 605 and step 606 are similar to the implementation of step 504 and step 505 corresponding to Fig. 5. For details, please refer to the description of step 504 and step 505. The details will not be described again here.

[0214] It can be known from the foregoing that in practical application, the RAN device may further deliver a RAN-visible application layer measurement configuration to the UE, and indicate to the UE to report some application layer indicators in a RAN device-detectable or visible format (e.g., information element format), which is also referred to as indicating to the UE to report RAN-visible application layer measurement results corresponding to some application indicators. The application layer indicators may include the RAN device-detectable application layer indicators in step 201. Details will not be described again here.

[0215] Optionally, the UE (e.g., an upper layer of the UE's AS) may obtain RAN-visible application layer indicator measurement results based on the measurement interval of the RAN-visible application layer measurement. For example, when the RAN-visible application layer indicator is at the buffer level and the RAN-visible application layer measurement configuration indicates to the UE to report the buffer level in the RAN-visible format, the RAN-visible application layer measurement configuration includes indication information #B indicating the maximum number of buffer-level entities reported in the RAN-visible application layer measurement. The upper layer of the UE's AS layer may also use the maximum number of entities to calculate the measurement interval of the buffer level in the RAN-visible application layer measurement. For example, the measurement interval is the RAN-visible application layer reporting period divided by the maximum number of entities. The RAN-visible application layer reporting period may be indicated in the RAN-visible application layer measurement configuration, or when the RAN-visible application layer measurement configuration does not indicate a RAN-visible application layer reporting period, the RAN-visible application layer reporting period is the reporting period indicated in the container for the application layer measurement configuration (the reporting period corresponding to the container for the application layer measurement results).

[0216] In order to reduce transmission overhead between the UE and the RAN device caused by reporting RAN visible application layer indicator measurement results by the UE, the RAN device may configure an event for reporting RAN visible application layer indicator measurement results for the UE, and determine whether the UE reports RAN visible application layer measurement results of the application layer indicator according to whether the event is triggered. When multiple RAN visible application layer indicator measurement results of a specific application layer indicator satisfy the event, the UE reports the RAN visible application layer measurement results of the application layer indicator; otherwise, the UE does not report the RAN visible application layer measurement results of the application layer indicator, or when multiple RAN visible application layer indicator measurement results of the specific application layer indicator satisfy the event, the UE does not report the RAN visible application layer measurement results of the application layer indicator; otherwise, the UE reports the RAN visible application layer measurement results of the application layer indicator.

[0217] For example, whether multiple measurement results of application layer indicators exceed a threshold may be used as an event, or whether multiple measurement results of application layer indicators are below a threshold may be used as an event. The threshold may be signaled to the UE by the RAN device in RAN visible application layer measurement configuration information, or may be a pre-specified value or a value determined by the UE.

[0218] For example, multiple measurements of a particular application layer indicator satisfying an event may include, but is not limited to, the following methods:

[0219] Method 1: The average value of multiple measurements satisfies the event.

[0220] Method 2: The maximum value of multiple measurements satisfies the event.

[0221] Method 3: The minimum value of multiple measurements satisfies the event.

[0222] Method 4: Only one of the measurements satisfies the event.

[0223] Method 5: All measurements of multiple measurements satisfy the event.

[0224] Method 6: All N2 measurement results among N1 measurement results among the multiple measurement results satisfy the event, where the values ​​of N1 and N2 may be notified to the UE by the RAN device in RAN-visible application layer measurement configuration information, or may be pre-specified values ​​or values ​​determined by the UE, and N1 is greater than or equal to N2.

[0225] Method 7: All N3 measurement results among the multiple measurement results satisfy the event, and the value of N3 may be notified to the UE by the RAN device in RAN-visible application layer measurement configuration information, or may be a pre-specified value or a value determined by the UE.

[0226] Method 8: All X consecutive measurement results among the multiple measurement results satisfy the event, and the value of X may be notified to the UE by the RAN device in RAN-visible application layer measurement configuration information, or may be a pre-specified value or a value determined by the UE.

[0227] Method 9: All Y measurement results among the latest X measurement results among the multiple measurement results satisfy the event, where the values ​​of X and Y may be notified to the UE by the RAN device in RAN-visible application layer measurement configuration information, or may be pre-specified values ​​or values ​​determined by the UE, and X is greater than or equal to Y.

[0228] The aforementioned multiple measurement results may be all measurement results within a time period period T, where T may be notified to the UE by the RAN device in RAN-visible application layer measurement configuration information (e.g., a reporting period or a measurement period of RAN-visible application layer measurements), or may be a pre-specified value or a value determined by the UE.

[0229] Alternatively, the aforementioned plurality of measurement results may be N measurement results, and the value of N may be notified to the UE by the RAN device in RAN-visible application layer measurement configuration information (e.g., the maximum number of entities indicated in indication information #B), or may be a pre-specified value or a value determined by the UE.

[0230] Alternatively, the above-mentioned multiple measurement results are measurement results included in one measurement result information received by the AS of the UE from an upper layer of the AS of the UE.

[0231] Optionally, after the UE receives the event from the RAN device, the AS of the UE sends a configuration of the event to an upper layer of the AS of the UE.

[0232] The UE determines whether to report the RAN-visible application layer indicator measurement results, i.e., determines whether multiple measurement results of a specific application layer indicator satisfy the corresponding event.

[0233] When multiple measurement results of a specific application layer indicator satisfy an event corresponding to the application layer indicator, the UE reports a RAN-visible application layer indicator measurement result corresponding to the application layer indicator; otherwise, the UE does not report a RAN-visible application layer indicator measurement result corresponding to the application layer indicator.

[0234] Alternatively, when multiple measurement results of a specific application layer indicator satisfy an event corresponding to the application layer indicator, the UE does not report a RAN-visible application layer indicator measurement result corresponding to the application layer indicator; otherwise, the UE reports a RAN-visible application layer indicator measurement result corresponding to the application layer indicator.

[0235] Specifically, the UE may determine whether to report RAN-visible application layer indicator measurement results at the UE AS layer or an upper layer of the UE AS layer. Optionally, when the UE AS determines whether to report RAN-visible application layer indicator measurement results, the measurement results are a plurality of RAN-visible application layer indicator measurement results received by the UE AS from an upper layer of the UE AS. The measurement results may be measurement results included in one measurement result information received by the UE AS from an upper layer, or may be measurement results included in a plurality of measurement result information received by the UE AS from an upper layer.

[0236] Optionally, reporting a RAN visible application layer indicator measurement result by the UE may be to report a specific RAN visible application layer indicator measurement result, i.e., a specific value, or may be to report that the RAN visible application layer indicator satisfies a corresponding event.
