Description

Communication method, device and storage medium

[0001] This disclosure claims priority to Chinese patent application No. 202310940808.7, filed on July 27, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular to communication methods, devices, and storage media. Background Art

[0003] 5G systems achieve network synchronization by referencing clock signals emitted by synchronous clocks. Synchronous clocks are typically generated by a master clock, which typically obtains clock information from a global navigation satellite system (GNSS) receiver. At the same time, in order to meet synchronization requirements even under fault conditions, the design of synchronous clocks typically includes devices to address potential degradation of GNSS clock signals. However, some deployments of 5G systems involve applications that are sensitive to any degradation of clock signals. In this case, the 5G system can be enhanced to serve as a backup for the loss of its GNSS reference. For example, the resilience enhancement of the 5G system can work in conjunction with different types of time sources to provide robust time synchronization.

[0004] In order to enable different types of time sources to work together in the 5G system, a clock source transformation mechanism needs to be designed in the 5G system. That is, the 5G system should be able to support a mechanism to provide terminals with alternative clock sources for use (for example, the 5G system includes: clock sources such as atomic clocks, fiber optic synchronization, terrestrial beacon system (TBS), GNSS, etc.).

[0073] The following will clearly and completely describe the technical solutions of this disclosure in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of this disclosure without making any creative efforts shall fall within the scope of protection of this disclosure.

[0074] It should be noted that in this disclosure, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present related concepts in some way.

[0075] In the following, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of the features.

[0076] In the description of this disclosure, unless otherwise specified, " / " means "or." For example, A / B can mean A or B. "And / or" herein is simply a way to describe an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: only A, only B, and both A and B. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0077] In a flexible clock system, the base station can only provide clock quality information to the terminal when the terminal enters the connected state. Since it takes a certain amount of time to transition from other states to the connected state, it will increase the terminal's latency and power consumption.

[0078] To address the above technical issues, embodiments of the present disclosure provide a communication method. The method utilizes a terminal that, while in a non-connected state, sends a first request message requesting clock quality information to a base station, and then receives the clock quality information sent by the base station. This allows the terminal to obtain clock quality information while in a non-connected state, resolving the technical issue of requiring the terminal to enter a connected state to obtain clock quality information. This method reduces latency and saves power consumption.

[0079] Quality of experience (QoE) measurement, as well as RAN-visible QoE (RVQoE) measurement performed in the radio access network (RAN), refers to measuring users' experience with service quality and performance (including aspects such as effectiveness and availability). This allows operators to comprehensively evaluate service quality and performance based on QoE measurement results, identify service problems, and adaptively adjust the communication network based on these problems.

[0080] Currently, with the development of the network, the speed of business updates is accelerating. How to implement QoE measurement and RVQoE measurement for new services has become an urgent problem to be solved.

[0081] In response to the above technical problems, an embodiment of the present disclosure provides a communication method, the idea of ​​which is that the terminal can send capability information to the base station (used to indicate that the terminal supports QoE and / or RVQoE measurements for newly added XR services) so that the base station can know the measurement capability of the terminal. In this way, when the base station receives the QoE and / or RVQoE measurement task for the XR service, it can instruct the terminal to perform measurement.

[0082] In connected mobility scenarios, if a mobile terminal switches from a source base station to a target base station during QoE measurement, the target base station cannot know whether the ongoing QoE measurement needs to be suspended or discarded. This makes it impossible to ensure the integrity of the QoE report in mobility scenarios. Therefore, the current QoE measurement efficiency in mobility scenarios is low, and the user experience is poor.

[0083] In response to the above technical problems, an embodiment of the present disclosure provides a communication method, the idea of ​​which is that: during the process of a terminal switching access from a source base station to a target base station, the first QoE configuration information configured by the source base station for the terminal is sent to the target base station, so that the target base station configures the second QoE configuration information according to the first QoE configuration information and sends it to the terminal, so that the terminal can perform QoE measurement according to the second QoE configuration information, thereby ensuring the continuity of QoE measurement, ensuring the integrity of QoE report, improving QoE measurement efficiency in mobility scenarios, and enhancing user experience.

[0084] The communication system provided by the embodiments of the present disclosure is introduced below with reference to the accompanying drawings.

[0085] 1 , which is a schematic diagram of the architecture of a communication system provided by an embodiment of the present disclosure. As shown in FIG1 , the communication system includes: a terminal 110 and a base station 120 .

[0086] The terminal 110 is configured to obtain clock quality information from the base station 120 .

[0087] In some embodiments, when a radio resource control (RRC) connection is established between the terminal 110 and the base station 120 (ie, when the terminal 110 is in the RRC connected state (RRC_CONNECT)), the terminal 110 obtains clock quality information from the base station 120 .

[0088] In some embodiments, when no RRC connection is established between the terminal 110 and the base station 120 (that is, when the terminal 110 is in the RRC inactive state (RRC_INACTIVE) and the RRC idle state (RRC_IDLE)), the terminal 110 can also obtain clock quality information from the base station 120.

[0089] The base station 120 is configured to send clock quality information to the terminal 110 .

[0090] In some embodiments, the base station 120 is further configured to send a paging message to the terminal 110 when the clock information changes. The paging message is used to inform the terminal 110 of the change in the clock information and trigger the terminal 110 to initiate a clock acquisition request.

[0095] The base station 220 is configured to obtain QoE configuration information from the core network element 230 and send the QoE configuration information to the terminal 210 .

[0096] In some embodiments, base station 220 may receive capability information sent by terminal 210 and determine whether terminal 210 has QoE measurement capability. Further, upon receiving a related QoE measurement task, base station 220 may send QoE configuration information of the QoE measurement task to terminal 210.

[0097] The core network element 230 is configured to send QoE configuration information to the base station 220 .

[0098] In some embodiments, the core network element 230 may be configured to detect whether there is a QoE measurement task for a related service in the network, and send QoE configuration information of the QoE measurement task to the base station 220 if there is a QoE measurement task for a related service in the network.

[0099] Exemplarily, the core network element 230 may be an access and mobility management function (AMF).

[0100] 3 , which is a schematic diagram of the architecture of another communication system provided by an embodiment of the present disclosure, as shown in FIG3 , the communication system includes: a terminal 310 , a source base station 320 , a target base station 330 , and a core network 340 .

[0101] The terminal 310 is configured to perform a QoE measurement task.

[0102] In some embodiments, the terminal 310 performs a QoE measurement task based on QoE configuration information, where the QoE configuration information is configured by the base station.

[0103] In some embodiments, the terminal 310 may switch access from the source base station 320 to the target base station 330 .

[0104] The source base station 320 is configured to send a handover request to the target base station 330 through the core network 340 when the terminal 310 switches access from the source base station 320 to the target base station 330 .

[0105] The target base station 330 is configured to send a handover request reply message to the source base station 320 through the core network 340 upon receiving the handover request message sent by the source base station 320 .

[0106] The core network 340 is used for forwarding information.

[0107] In some embodiments, the core network 340 is used to receive a switching request message sent by the source base station 320 and send a switching request message to the target base station 330; and to receive a switching request reply message sent by the target base station 330 and send a switching command to the source base station 320.

[0108] In some embodiments, the core network 340 is further configured to receive dedicated signaling sent by the target base station 330 and send dedicated signaling to the source base station 320 .

[0109] Exemplarily, the core network 340 may be a network element in the core network 340 .

[0110] For example, the terminals (including terminal 110, terminal 210, or terminal 310) may be mobile phones, tablet computers, desktop computers, laptop computers, handheld computers, notebook computers, ultra-mobile personal computers (UMPCs), netbooks, cellular phones, personal digital assistants (PDAs), augmented reality (AR) and virtual reality (VR) devices, etc. The embodiments of the present disclosure do not impose any particular limitation on the specific form of the terminals.

[0111] It should be noted that the system architecture and application scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0112] The communication method provided by the embodiment of the present disclosure is introduced below.

[0113] As shown in FIG4 , the communication method provided in the embodiment of the present disclosure is applied to the communication system shown in FIG1 . The method may include the following steps:

[0114] S401: A terminal sends first indication information to a base station. Correspondingly, the base station receives the first indication information sent by the terminal.

[0115] The first indication information is used to indicate a request for clock quality information.

[0116] In some embodiments, as shown in FIG5 , the above step S401 may be implemented as the following step S401a.

[0117] S401a: During a random access process, the terminal sends MSG1 or MSG3 to the base station. MSG1 or MSG3 includes first indication information, and the first indication information is used to indicate a request for clock quality information. Accordingly, the base station receives MSG1 or MSG3 sent by the terminal and obtains the first indication information from MSG1 or MSG3.

[0118] It is understood that the random access procedure can be a two-step random access procedure or a four-step random access procedure. For example, in a two-step random access procedure, the terminal sends MSG1 to the base station, and MSG1 includes the first indication information. In a four-step random access procedure, the terminal sends MSG3 to the base station, and MSG3 includes the first indication information.

[0119] In some embodiments, the base station may send a reference clock-related event identifier in a broadcast manner; accordingly, the terminal receives the reference clock-related event identifier sent by the base station, and when the reference clock-related event identifier sent by the base station is different from the reference clock-related event identifier stored in the terminal, the terminal sends a first indication message to the base station to request clock quality information.

[0120] It can be understood that when the event identifier related to the reference clock sent by the base station is different from the event identifier related to the reference clock stored in the terminal, it means that the clock quality information stored in the terminal needs to be updated. Therefore, the terminal can actively send a first indication information for requesting clock quality information to the base station to obtain new clock quality information.

[0121] In some embodiments, as shown in FIG6 , the above step S401 can be implemented as the following step S401b.

[0122] S401b: The terminal sends user equipment assistance information (UE Assistance Information) to the base station. Correspondingly, the base station receives the user equipment assistance information sent by the terminal to the base station.

[0123] The user equipment auxiliary information includes first indication information and second indication information; the first indication information is used to indicate a request for clock quality information; and the second indication information is used to indicate a change in the clock quality information.

[0124] Exemplarily, the user equipment auxiliary information includes resume cause information, and the resume cause information may include first indication information and second indication information.

[0125] It is understandable that the base station can learn that the clock quality information of the terminal has changed based on the second indication information included in the user equipment auxiliary information, and then actively send the clock quality information to the terminal based on the first indication information included in the user equipment auxiliary information.

[0126] In some embodiments, as shown in FIG7 , the above method further includes the following step S400 .

[0127] S400: The base station sends a paging message to the terminal. Correspondingly, the terminal receives the paging message sent by the base station.

[0128] The paging message includes at least one of the following: second indication information, third indication information, and fourth indication information. The second indication information is used to indicate that the clock quality information has changed; the third indication information is used to trigger the terminal to initiate a two-step random access procedure; and the fourth indication information is used to trigger the terminal to initiate a four-step random access procedure.

[0129] It is understandable that, when detecting a change in the clock quality information, the base station may proactively initiate a paging message to trigger the terminal to obtain the clock quality information from the base station, so as to update the clock quality information stored in the terminal.

[0130] S402: The base station sends clock quality information to the terminal. Correspondingly, the terminal receives the clock quality information sent by the base station.

[0131] The clock quality information includes at least one of the following: time source, synchronization status, clock type, clock accuracy, reference clock information, and reference report identifier.

[0132] In some embodiments, step S401 may be implemented as follows: during a random access process, the base station sends a message (MSG) 2 or MSG 4 to the terminal, where MSG 2 or MSG 4 includes clock quality information. Accordingly, the terminal receives MSG 2 or MSG 4 sent by the base station and obtains the clock quality information from MSG 2 or MSG 4.

[0133] During the above random access process, the terminal is in the RRC_INACTIVE state.

[0134] As a possible implementation manner, MSG2 or MSG4 includes a small data transmission (SDT) data packet, and the small data transmission data packet includes clock quality information.

[0135] As another possible implementation manner, MSG2 or MSG4 includes downlink information transfer (DL information transfer) signaling, and the downlink information transfer signaling includes clock quality information.

[0136] It is understood that the random access procedure described above may be a two-step random access procedure or a four-step random access procedure. For example, in a two-step random access procedure, the base station sends MSG2 to the terminal, where MSG2 includes clock quality information. In a four-step random access procedure, the base station sends MSG4 to the terminal, where MSG4 includes clock quality information.

[0137] It can be understood that the communication method provided by the embodiment of the present disclosure, by carrying clock quality information in SDT or downlink information transmission signaling, enables the terminal to obtain clock quality information in the RRC_INACTIVE state, thereby solving the technical problem that the terminal must enter the RRC_CONNECT state to obtain clock quality information, and can reduce latency and save power consumption of the terminal.

[0138] In some embodiments, the above step S402 may be implemented as follows: after entering the RRC_CONNECT state, the terminal receives the clock quality information sent by the base station.

[0139] Exemplarily, the terminal may enter the RRC_CONNECT state by actively initiating RRC establishment or RRC re-establishment.

[0140] In some embodiments, when the terminal is in a non-connected state (for example, RRC_IDL state or RRC_INACTIVE state), the base station may send a reference clock-related event identifier in a broadcast manner; accordingly, the terminal receives the reference clock-related event identifier sent by the base station, and when the reference clock-related event identifier sent by the base station is different from the reference clock-related event identifier stored in the terminal, it switches from the non-connected state to the connected state to obtain the clock quality information sent by the base station.

[0141] For ease of understanding, the communication method provided in the embodiments of the present disclosure is described below using different scenarios as examples.

[0142] Scenario 1: Obtaining clock quality information in a two-step random access process.

[0143] For example, as shown in FIG8 , in scenario 1, the communication method provided by the embodiment of the present disclosure can be implemented as follows:

[0144] Sa1: The terminal sends MSG1 to the base station. The MSG1 includes first indication information, and the first indication information is used to indicate a request for clock quality information. Correspondingly, the base station receives the MSG1 sent by the terminal and obtains the first indication information from the MSG1.

[0145] Sa2: The base station sends MSG2 to the terminal, and MSG2 includes clock quality information. Correspondingly, the terminal receives MSG2 sent by the base station and obtains the clock quality information from MSG2.

[0146] Exemplarily, MSG2 includes an SDT data packet, which includes clock quality information; or, MSG2 includes downlink information transmission signaling, which includes clock quality information.

[0147] For example, as shown in FIG9 , in scenario 1, the communication method provided by the embodiment of the present disclosure may also be implemented as the following steps:

[0148] Sb1. The base station sends a paging message to the terminal. Correspondingly, the terminal receives the paging message sent by the base station.

[0149] The paging message includes: second indication information and third indication information.

[0150] It is understandable that after receiving the paging message, the terminal learns that the clock quality information has changed based on the second indication information in the paging message; and triggers a two-step random access process based on the third indication information in the paging message to obtain new clock quality information.

[0151] Sb2: The terminal sends MSG1 to the base station. Correspondingly, the base station receives MSG1 sent by the terminal.

[0152] Sb3: The base station sends MSG2 to the terminal, where MSG2 includes clock quality information. Correspondingly, the terminal receives MSG2 sent by the base station and obtains the clock quality information from MSG2.

[0153] For example, the exemplary implementation of step Sb3 can refer to the above-mentioned step Sa2, which will not be described in detail here.

[0154] Scenario 2: Obtain clock quality information during the four-step random access process.

[0155] For example, as shown in FIG10 , in scenario 2, the communication method provided by the embodiment of the present disclosure can be implemented as follows:

[0156] Sc1. The terminal sends MSG1 to the base station. The MSG1 includes first indication information, and the first indication information is used to indicate a request for clock quality information. Correspondingly, the base station receives the MSG1 sent by the terminal and obtains the first indication information from the MSG1.

[0157] Sc2. The base station sends MSG2 to the terminal, where MSG2 includes clock quality information. Correspondingly, the terminal receives MSG2 sent by the base station and obtains the clock quality information from MSG2.

[0158] Exemplarily, MSG2 includes an SDT data packet, which includes clock quality information; or, MSG2 includes downlink information transmission signaling, which includes clock quality information.

[0159] Sc3. The terminal sends MSG3 to the base station. Correspondingly, the base station receives MSG3 sent by the terminal.

[0160] Sc4. The base station sends MSG4 to the terminal. Correspondingly, the terminal receives MSG4 sent by the base station.

[0161] For example, as shown in FIG11 , in scenario 2, the communication method provided by the embodiment of the present disclosure may also be implemented as the following steps:

[0162] Sd1: The terminal sends MSG1 to the base station. Correspondingly, the base station receives MSG1 sent by the terminal.

[0163] Sd2: The base station sends MSG2 to the terminal. Correspondingly, the terminal receives MSG2 sent by the base station.

[0164] Sd3: The terminal sends MSG3 to the base station. MSG3 includes first indication information, and the first indication information is used to indicate a request for clock quality information. Correspondingly, the base station receives MSG3 sent by the terminal and obtains the first indication information from MSG3.

[0165] Sd4: The base station sends MSG4 to the terminal, and MSG4 includes clock quality information. Correspondingly, the terminal receives MSG4 sent by the base station and obtains the clock quality information from MSG4.

[0166] For example, as shown in FIG12 , in scenario 2, the communication method provided by the embodiment of the present disclosure may also be implemented as the following steps:

[0167] Se1: The base station sends a paging message to the terminal. Correspondingly, the terminal receives the paging message sent by the base station.

[0168] The paging message includes: second indication information and fourth indication information.

[0169] It is understandable that after receiving the paging message, the terminal learns that the clock quality information has changed based on the second indication information in the paging message; and triggers a four-step random access process based on the fourth indication information in the paging message to obtain new clock quality information.

[0170] Se2. The terminal sends MSG1 to the base station. Correspondingly, the base station receives MSG1 sent by the terminal.

[0171] Se3. The base station sends MSG2 to the terminal, and MSG2 includes clock quality information. Correspondingly, the terminal receives MSG2 sent by the base station and obtains the clock quality information from MSG2.

[0172] Se4. The terminal sends MSG3 to the base station. Correspondingly, the base station receives MSG3 sent by the terminal.

[0173] Se5. The base station sends MSG4 to the terminal. Correspondingly, the terminal receives MSG4 sent by the base station.

[0174] It is understood that the above embodiment is described by taking the example of the base station carrying the clock quality information in MSG2. In some embodiments, the base station may also carry the clock quality information in MSG4, which will not be described in detail here.

[0175] Scenario 3: The terminal enters the connected state to obtain clock quality information.

[0176] For example, as shown in FIG13 , in scenario 2, the communication method provided by the embodiment of the present disclosure can be implemented as follows:

[0177] Sf1: The base station sends a broadcast message including an event identifier related to the reference clock. Correspondingly, the terminal receives the broadcast message sent by the base station and obtains the event identifier related to the reference clock from the broadcast message.

[0178] Sf2. When the reference clock-related event identifier sent by the base station is different from the reference clock-related event identifier stored in the terminal, the terminal switches from the unconnected state to the connected state.

[0179] Sf3: The terminal sends the user equipment auxiliary information to the base station. Correspondingly, the base station receives the user equipment auxiliary information sent by the terminal to the base station.

[0180] The user equipment auxiliary information includes first indication information or second indication information; the first indication information is used to indicate a request for clock quality information; the second indication information is used to indicate a change in the clock quality information.

[0181] Sf4. The base station sends the clock quality information to the terminal. Correspondingly, the terminal receives the clock quality information sent by the base station.

[0182] It is understandable that, when the reference clock-related event identifier sent by the base station is different from the reference clock-related event identifier stored in the terminal, the terminal switches from the unconnected state to the connected state to obtain clock quality information. At the same time, in order for the base station to recognize that the terminal enters the connected state for the purpose of obtaining clock quality information, the terminal may send user equipment auxiliary information (including the first indication information or the second indication information) to the base station, so that the base station sends the clock quality information to the terminal.

[0183] As shown in FIG14 , the communication method provided in the embodiment of the present disclosure is applied to the communication system shown in FIG2 . The method may include the following steps:

[0184] S501: A terminal sends capability information to a base station. Correspondingly, the base station receives the capability information sent by the terminal.

[0185] The capability information is used to indicate that the terminal supports QoE and / or RVQoE measurement for extended reality (XR) services.

[0186] In some embodiments, the capability information includes QoE configuration parameters (QoE-Parameters), and the QoE-Parameters include the XR service type.

[0187] It can be understood that the base station learns that the terminal supports QoE and / or RVQoE measurements for XR services based on the capability information sent by the terminal. In this way, when the base station receives the QoE and / or RVQoE measurement task for the XR service, it can forward it to the terminal to instruct the terminal to perform QoE and / or RVQoE measurements for the XR service.

[0188] S502: The core network element sends QoE configuration information to the base station. Correspondingly, the base station receives the QoE configuration information sent by the core network element.

[0189] In some embodiments, the QoE configuration information includes: XR service type indication information, where the XR service type indication information is used to indicate the XR service type for the terminal to perform QoE and / or RVQoE measurement.

[0190] It can be understood that the embodiment of the present disclosure can carry XR service type indication information in the QoE configuration information. In this way, the base station can determine that the measurement task corresponding to the QoE configuration information is for the XR service, and then allocate a terminal that supports QoE and / or RVQoE measurement for the XR service to the measurement task.

[0191] In some embodiments, since XR services require frequent updates and tight synchronization of motion or control data in coordination with one or more downlink (DL) video streams and uplink (UL), the QoE configuration information may also include at least one of the following measurement indicators: monocular resolution, field of view, angular resolution, 360-degree panoramic resolution, multipath transmission delay, bit rate, and immersion.

[0192] In some embodiments, as shown in FIG15 , the above step S502 may be implemented as the following steps S5021:

[0193] S5021. The core network element sends service experience measurement collection (QoE measurement collection, QMC) configuration information to the base station. The QMC configuration information carries QoE configuration information.

[0194] S503: The base station sends QoE configuration information to the terminal. Correspondingly, the terminal receives the QoE configuration information sent by the base station.

[0195] In some embodiments, as shown in FIG15 , the above step S503 may implement the following steps S5031:

[0196] S5031. The base station sends an RRC re-establishment message or an RRC recovery message to the terminal. The RRC re-establishment message or the RRC recovery message carries QoE configuration information.

[0197] In some embodiments, the terminal performs QoE and / or RVQoE measurements on the XR service based on the QoE configuration information sent by the base station.

[0198] It can be understood that in the communication method provided in the embodiment of the present disclosure, the terminal can send capability information (used to indicate that the terminal supports QoE and / or RVQoE measurements for XR services) to the base station so that the base station can know the measurement capability of the terminal. In this way, when the base station receives the QoE and / or RVQoE measurement task for the XR service, it can instruct the terminal to perform the measurement.

[0199] As shown in FIG16 , the communication method provided in the embodiment of the present disclosure is applied to the communication system shown in FIG3 . The method may include the following steps:

[0200] S601: A source base station sends first QoE configuration information to a target base station. Correspondingly, the target base station receives the first QoE configuration information sent by the source base station.

[0201] The first QoE configuration information is QoE configuration information configured by the source base station for the QoE measurement task being performed by the terminal.

[0202] Exemplarily, the first QoE configuration information may include at least one of the following: service type, measurement configuration application layer container, measurement indicator, reporting server information, reporting interval, session QoE measurement collection identifier, and QoE area range information.

[0203] In some embodiments, the above S601 may be implemented as follows: the source base station sends the first QoE configuration information to the target base station via a core network element. Accordingly, the target base station receives the first QoE configuration information sent by the source base station via the core network element.

[0204] For example, as shown in FIG. 17 or FIG. 18 , the above step S601 may be implemented as the following steps S6011-S6012:

[0205] S6011. The source base station sends a handover request to a core network element. The handover request carries first QoE configuration information.

[0206] S6012: The core network element sends a handover request to the target base station, where the handover request carries the first QoE configuration information. Accordingly, the target base station receives the handover request sent by the core network element and obtains the first QoE configuration information from the handover request.

[0207] S602: The target base station sends second QoE configuration information to the source base station. Correspondingly, the source base station receives the second QoE configuration information sent by the target base station.

[0208] The second QoE configuration information is QoE configuration information that requires continuous measurement and is configured by the target base station for the QoE measurement task being performed by the terminal according to the first QoE configuration information.

[0209] Exemplarily, the second QoE configuration information may include at least one of the following: service type, measurement configuration application layer container, measurement indicator, reporting server information, reporting interval, session QoE measurement collection identifier, and QoE area range information.

[0210] In some embodiments, the above S602 may be implemented as follows: the target base station sends the second QoE configuration information to the source base station via a core network element. Correspondingly, the source base station receives the second QoE configuration information sent by the target base station via the core network element.

[0211] For example, as shown in FIG17 , the above step S602 may be implemented as the following steps S6021a-S6022a:

[0212] S6021a. The target base station sends a dedicated signaling to a core network element. The dedicated signaling carries the second QoE configuration information.

[0213] S6022a: The core network element sends a dedicated signaling to the source base station, where the dedicated signaling carries the second QoE configuration information. Accordingly, the source base station receives the dedicated signaling sent by the core network element and obtains the second QoE configuration information from the dedicated signaling.

[0214] For example, as shown in FIG18 , the above step S602 may be implemented as the following steps S6021b-S6022b:

[0215] S6021b. The target base station sends a handover request reply message to the core network element. The handover request reply message carries the second QoE configuration information.

[0216] S6022b: The core network element sends a handover command to the source base station, where the handover command carries the second QoE configuration information. Accordingly, the source base station receives the handover command sent by the core network element and obtains the second QoE configuration information from the handover command.

[0217] S603: The source base station sends second QoE configuration information to the terminal. Correspondingly, the terminal receives the second QoE configuration information sent by the source base station.

[0218] In some embodiments, as shown in FIG. 17 and FIG. 18 , the above step S603 may be implemented as the following step S6031 .

[0219] S6031. The source base station sends a handover command to the terminal, where the handover command includes second QoE configuration information.

[0220] Correspondingly, the terminal receives the handover command sent by the source base station, switches access from the source base station to the target base station in response to the handover command, and performs QoE measurement based on the second QoE configuration information carried in the handover command.

[0221] It can be understood that, based on the communication method provided in the embodiment of the present disclosure, during the process of the terminal switching access from the source base station to the target base station, the first QoE configuration information configured by the source base station for the QoE measurement task being performed by the terminal can be sent to the target base station, so that the target base station configures the second QoE configuration information according to the first QoE configuration information and sends it to the terminal, so that the terminal can perform QoE measurement according to the second QoE configuration information, which can ensure the continuity of QoE measurement, ensure the integrity of QoE report, improve the QoE measurement efficiency in mobility scenarios, and enhance the user experience.
