1. QoE measurement

QoE measurement refers to measuring the comprehensive subjective use experience of users on the quality and performance (including the aspects of availability and availability) of services, that is, measuring the use experience of users using service applications, so that an operator can comprehensively evaluate the quality and performance of services through QoE measurement results, so that the operator can know the problems of the services according to the comprehensive evaluation results of the users on the services, and can adaptively adjust the communication network according to the problems of the services.

Note that QoE measurement includes: 1.1, signaling-based QoE measurements, and 1.2, management-based QoE measurements. The following will respectively describe in detail:

1.1 QoE measurement based on Signaling

The signaling-based QoE measurement refers to QoE measurement performed for a specific terminal device, and the signaling-based QoE measurement may be performed in real time.

As shown in fig. 1, the signaling-based QoE measurement procedure includes the following S101-S108.

S101, an Access Stratum (AS) layer of the terminal device sends capability information to a radio access base station (next generation radio access network, NG-RAN) in a fifth generation mobile communication technology (5th generation mobile communication technology,5G) network. Accordingly, the NG-RAN receives the transmission capability information from the AS layer of the terminal device.

Wherein the capability information is used to characterize the capability of the terminal device to have QoE measurement.

In a possible implementation, the capability information may be Capability Information information sent by the terminal device to the NG-RAN.

S102, operation and maintenance management (operation administration and maintenance, OAM) sends configuration QoE measurement information to the core network device. Correspondingly, the core network device receives the configured QoE measurement information from the OAM.

The QoE measurement information is configured to trigger the core network device to perform QoE measurement configuration and carry QoE measurement configuration parameters.

In a possible implementation manner, the QoE measurement information may be Configure QoE Measurement information sent by the OAM to the core network device.

It should be noted that the above configured QoE measurement information may include a configuration range of QoE measurement, and required QoE measurement configuration parameters.

It should be noted that, if the NG-RAN determines, according to the capability information, that the terminal device does not have the capability of QoE measurement, the OAM may also send configuration QoE measurement information to the core network device. That is, in the case where the NG-RAN determines from the capability information that the terminal device does not have the capability of QoE measurement, S102 to S103 are continued to be performed, but S104 to S108 are not continued to be performed.

And S103, the core network equipment sends the QoE measurement activating information to the NG-RAN. Accordingly, the NG-RAN receives active QoE measurement information from the core network device.

The QoE measurement activating information includes QoE measurement configuration parameters.

In a possible implementation, the active QoE measurement information may be Activate QoE Measurement information that the core network device sends to the NG-RAN.

It should be noted that, after receiving the configured QoE measurement information from the OAM, the core network device generates the active QoE measurement information according to the configured QoE measurement information.

S104, the NG-RAN sends the radio resource control information to an AS layer of the terminal equipment. Correspondingly, the AS layer of the terminal equipment receives the radio resource control information from the NG-RAN.

The radio resource control information includes QoE measurement configuration parameters.

The radio resource control information is transmitted by the NG-RAN to the terminal device in the form of radio resource control signaling.

In one possible implementation, the radio resource control information may be RRC Message information sent by the NG-RAN to an access layer of the terminal device.

S105, the terminal equipment AS layer sends a mobile terminal command to a terminal equipment Application (APP) layer. Correspondingly, the terminal device APP layer receives the mobile terminal command from the AS layer of the terminal device.

The mobile terminal command includes a QoE measurement configuration parameter.

In one possible implementation, the mobile terminal command may be Access Terminate command.

S106, the terminal equipment APP layer sends a mobile terminal command to the terminal equipment AS layer. Correspondingly, the terminal equipment AS layer receives a mobile terminal command from the terminal equipment APP layer.

The mobile terminal command is used for indicating the terminal equipment APP layer to report the QoE measurement report to the AS layer of the terminal.

In a possible implementation, the configured QoE measurement information may be Access Terminate command.

It should be noted that, after receiving a mobile terminal command including a QoE measurement configuration parameter sent by an AS layer of a terminal device, an APP layer of the terminal device performs QoE measurement according to the QoE measurement configuration parameter, and generates a QoE measurement report.

S107, the AS layer of the terminal equipment sends the radio resource control information to the NG-RAN. Correspondingly, the NG-RAN receives radio resource control information from the AS layer of the terminal device.

The radio resource control information includes a QoE measurement report.

In a possible implementation manner, the radio resource control information may be RRC Message information sent by the AS layer of the terminal device to the NG-RAN.

S108, NG-RAN sends QoE measurement reports to the terminal control unit (terminal control element, TCE)/medium access control unit (media access control element, MCE). Accordingly, the TCE/MCE receives QoE measurement reports from the NG-RAN.

In one possible implementation, the configured QoE measurement information may be QoE Report sent by the NG-RAN to the TCE/MCE.

The procedure of the signaling-based QoE measurement is described in detail above. The QoE measurement based on management will be described in detail below.

1.2 QoE measurement based on management

The management-based QoE measurement refers to QoE measurement performed for all terminal devices connected to a specific NG-RAN, and is used for a post-processing stage (i.e., the next stage performed after the pre-processing stage is completed).

As shown in fig. 2, the management-based QoE measurement procedure includes the following S201-S207.

S201, an AS layer of the terminal equipment sends capability information to the NG-RAN. Accordingly, the NG-RAN receives the transmission capability information from the AS layer of the terminal device.

It should be noted that S201 is similar to S101, and may be understood with reference to S101, and will not be described here again.

S202, the OAM sends activation QoE measurement information to the NG-RAN. Accordingly, the NG-RAN receives the active QoE measurement information from the OAM.

The QoE measurement activating information carries QoE measurement configuration parameters.

In one possible implementation, the active QoE measurement information may be Activate QoE Measurement information that the OAM sends to the NG-RAN.

The difference between S202 and S102 is that: s202 may send activation QoE measurement information directly by OAM to the NG-RAN; and S102 needs to send the configured QoE measurement information to the core network device by OAM, and then generate the active QoE measurement information by the core network device according to the configured QoE measurement information, and send the active QoE measurement information to the NG-RAN. Since the management-based QoE measurement does not require a core network device to relay information, the active QoE measurement information may be sent directly by OAM to the NG-RAN.

S203, the NG-RAN sends the radio resource control information to an AS layer of the terminal equipment. Correspondingly, the AS layer of the terminal equipment receives the radio resource control information from the NG-RAN.

It should be noted that S203 is similar to S104, and can be understood with reference to S104, and will not be described here.

S204, the terminal equipment AS layer sends a mobile terminal command to the terminal equipment APP layer. Correspondingly, the terminal device APP layer receives the mobile terminal command from the AS layer of the terminal device.

It should be noted that S204 is similar to S105, and can be understood with reference to S105, and will not be repeated here.

S205, the terminal equipment APP layer sends a mobile terminal command to the terminal equipment AS layer. Correspondingly, the terminal equipment AS layer receives a mobile terminal command from the terminal equipment APP layer.

It should be noted that S205 is similar to S106, and can be understood with reference to S106, and will not be described here.

S206, the AS layer of the terminal equipment sends the radio resource control information to the NG-RAN. Correspondingly, the NG-RAN receives radio resource control information from the AS layer of the terminal device.

It should be noted that S206 is similar to S107 described above, and can be understood with reference to S107 described above, and will not be repeated here.

S207, NG-RAN sends QoE measurement report to TCE/MCE. Accordingly, the TCE/MCE receives QoE measurement reports from the NG-RAN.

It should be noted that S207 is similar to S108, and may be understood with reference to S108, and will not be repeated here.

The terminal device 503 may be a terminal (terminal equipment) or a user equipment (ue) or a Mobile Station (MS) or a Mobile Terminal (MT), etc. Specifically, the plurality of terminal devices may be mobile phones, tablet computers or computers with wireless transceiver functions, and may also be Virtual Reality (VR) terminals, augmented reality (augmented reality, AR) terminals, wireless terminals in industrial control, wireless terminals in unmanned driving, wireless terminals in telemedicine, wireless terminals in smart grids, wireless terminals in smart cities (smart homes), vehicle-mounted terminals, and the like.

The access network device 501 receives QoE measurement configuration information sent by the OAM device or QoE measurement configuration information sent by the core network device. Further, the access network device 501 generates QoE measurement information including a measurement range based on the QoE measurement configuration information, and transmits the QoE measurement information including the measurement range to the terminal device 503. Accordingly, the terminal device 503 receives QoE measurement information including a measurement range sent by the access network device 501.

The access network device 502 may be a target access network device in an embodiment of the present application. After receiving QoE measurement information including a measurement range sent by the access network device 501, the terminal device 503 is in an idle state, and moves to a cell covered by the access network device 502 in the idle state. And, the access network device 502 transmits a request message for acquiring the QoE context of the terminal device 503 to the access network device 501 after establishing the RRC connection with the terminal device 501.

The terminal device 503 receives QoE measurement information including a measurement range sent by the access network device 501 in a cell covered by the access network device 501, and transitions from a connected state to an idle state in the cell covered by the access network device 501. Subsequently, the terminal device 503 in the idle state enters the cell coverage of the access network device 503, and enters the connected state from the idle state.

In addition, the communication system described in the embodiments of the present application is for more clearly describing the technical solution of the embodiments of the present application, and does not constitute a limitation on the technical solution provided in the embodiments of the present application, and as a person of ordinary skill in the art can know, with evolution of the network architecture and appearance of a new communication system, the technical solution provided in the embodiments of the present application is equally applicable to similar technical problems.

Because the terminal device can receive the broadcast service in both the idle state and the inactive state, the network side needs to acquire the QoE of the terminal device in the idle state or inactive state for the broadcast service, so as to acquire the overall approval degree of the terminal device in the idle state or inactive state for the service or service used.

In order to solve the problems in the prior art, the embodiment of the application provides a communication method applied to a terminal device. As shown in fig. 6, the method includes: S601-S603.

S601, the terminal equipment receives a QoE measurement configuration message sent by the source access network equipment.

The QoE measurement configuration message is used for indicating the terminal device to perform QoE measurement on the broadcast service MBS in the measurement area, where the QoE measurement configuration message includes the measurement area.

As one possible implementation, the terminal device sends a quality of experience QoE measurement configuration message through a physical downlink control channel (physical downlink control channel, PDCCH) source access network device.

In some embodiments, when the terminal device is in a connected state, the RRC signaling sent by the access network device is received, where the RRC signaling is used to carry the QoE measurement configuration message.

For example, the QoE measurement configuration message may be:

in other embodiments, the terminal device connection state receives a QoE measurement configuration message sent by the source access network device, where the QoE measurement configuration message does not include a QoE measurement region. Subsequently, when the terminal equipment enters an idle state or a non-activated state from a connection state, an RRC release message sent by the access network equipment is received, wherein the RRC release message comprises a QoE measurement area.

S602, after the terminal equipment enters a non-connection state, if the terminal equipment performs cell reselection, judging whether the terminal equipment is located in a measurement area.

As a possible implementation manner, after the terminal device enters the non-connected state, if the terminal device performs cell reselection, the position of the terminal device is obtained, and whether the position of the terminal device is located in the measurement area is determined, so as to determine whether the terminal device is located in the measurement area.

It should be noted that, the unconnected state may be an idle state or an inactive state.

S603, if the terminal equipment enters a connection state in the coverage area of the target access network equipment under the condition that the terminal equipment is located in the measurement area, the terminal equipment sends an indication message to the target access network equipment.

The target access network equipment is access network equipment after the terminal equipment cell reselection in an idle state; the indication message is used for indicating the target access network equipment to send a measurement result obtained by QoE measurement on the MBS.

As a possible implementation manner, if the terminal device in the idle state enters the connection state in the coverage area of the target access network device under the condition that the terminal device is located in the measurement area, an RRC establishment complete message is generated, and the indication message is carried in the RRC establishment complete message. Further, the terminal device sends an RRC setup complete message to the target access network device.

In some embodiments, if the terminal device in the idle state enters the connected state in the coverage area of the target access network device under the condition that the terminal device is located in the measurement area, RRC signaling is generated, and the indication message is carried in the RRC signaling. Further, the terminal device sends the RRC signaling to the target access network device.

Illustratively, the indication message includes the elements shown in table 1:

TABLE 1

When the terminal device sends the indication message, the terminal device already measures the MBS service and obtains a measurement result. Or when the terminal equipment sends the indication message, the terminal equipment does not measure the MBS service to be measured yet.

The indication message includes a unique identifier of the terminal device on the XN application flow (XN application process, XNAP), an identifier of the coverage cell of the source access network device, and a cell identifier where the current terminal device is located.

In one design, in order to avoid that a terminal device in a non-connected state continues to perform QoE measurement outside a measurement area, the embodiment of the present application provides a communication method, after determining whether the terminal device is located in the measurement area, the method further includes: s604.

S604, the terminal equipment stops QoE measurement of the MBS under the condition that the terminal equipment is not located in the measurement area.

As a possible implementation manner, if the terminal device determines that the terminal device is not located in the measurement area and if it is determined that the terminal device further includes an unmeasured MBS, the terminal device stops QoE measurement on the unmeasured MBS.

In some embodiments, if the terminal device determines that the terminal device is not located in the measurement area, if it is determined that there is an MBS that is performing QoE measurement, the terminal device suspends the MBS that performs QoE measurement on the MBS that performs QoE measurement.

In some embodiments, if the terminal device determines that the terminal device is not located in the measurement area and if it is determined that the terminal device further includes an unmeasured MBS, the terminal device releases the QoE measurement configuration for the unmeasured MBS.

In one design, in order to avoid two identical application layer identifiers of terminal devices located in the same target access network device, the embodiment of the application proposes a communication method, after sending an indication message to the target access network device, the method further includes: S605-S606.

S605, the terminal equipment receives a target application layer identification sent by the target access network equipment.

The target application layer identifier is used for identifying the QoE measurement configuration message, and is generated for the target access network equipment.

S606, the terminal equipment sends a measurement result to the target access network equipment according to the target application layer identification.

As a possible implementation manner, after the terminal device obtains the target application layer identifier, the target application layer identifier is added into the measurement result, and the measurement result is sent to the target access network device.

In order to solve the problems in the prior art, the embodiment of the application provides a communication method which is applied to source access network equipment before cell reselection of terminal equipment. As shown in fig. 7, the method includes: S701-S702.

S701, the source access network device generates a quality of experience QoE measurement configuration message.

As one possible implementation manner, the source access network device receives QoE measurement information sent by the OAM device, and generates a quality of experience QoE measurement configuration message based on the QoE measurement information.

As another possible implementation manner, the source access network device receives QoE measurement information sent by the core network device, and generates a quality of experience QoE measurement configuration message based on the QoE measurement information.

It should be noted that, the two manners of obtaining QoE measurement information correspond to a management-based QoE measurement procedure in the first manner, and correspond to a signaling-based QoE measurement procedure in the second manner. In a second manner, the QoE measurement configuration information sent by the core network device is sent by the OAM device to the core network device. The difference is that under the QoE measurement flow based on signaling, the terminal equipment to be measured is the terminal equipment specified in the QoE measurement configuration information; under the QoE measurement flow based on management, the terminal equipment to be measured is any terminal equipment under the coverage area of the access network equipment specified in the QoE measurement configuration information.

For example, as shown in table 2, the QoE measurement information may include at least one of: application layer metric configuration information (Container for application layer measurement configuration), a selection range (CHOICE Area Scope of QMC) of quality monitoring and control (Quality Monitoring and Control, QMC), cell base information (Cell based), a Cell identification List (Cell ID List for QMC) of QMC, 4G global Cell Identity (E-CGI), tracking area base information (TA based), tracking area List (TA List for QMC) of QMC, tracking area code base information (TAI based), tracking Area Identification (TAI), tracking area identification List (TAI List for QMC) of QMC, tracking Area Code (TAC), public land mobile network area base information (PLMN area based) of QMC, public land mobile network List (PLMN List for QMC) of QMC, public land mobile network identification (PLMN Identity), service Type information (Service Type).

In practical application, the QoE measurement configuration information based on the signaling further includes an identifier for specifying the terminal device. The management-based QoE measurement configuration information also includes an identification of the access network device. In addition, the QoE measurement configuration information further includes a target IP address of the TCE/MCE, so that after the terminal device to be measured completes QoE measurement, the measurement result is sent to the TCE/MCE according to the target IP address. The TCE/MCE may be a TCE/MCE preset by an operation and maintenance personnel, and is configured to receive measurement results of terminal devices to be measured under different access network devices.

The target access network equipment is access network equipment after the terminal equipment cell reselection.

It can be understood that after the terminal device receives the QoE measurement configuration message sent by the source access network device, when the terminal device enters a cell reselection in a non-connected state, the terminal device acquires the location of the terminal device again, and determines whether the terminal device is located in the measurement area based on the location of the terminal device and the measurement area. When the terminal equipment is in a connection state, the terminal equipment does not judge whether the position of the terminal equipment is located in a measurement area or not when the terminal equipment performs cell reselection.

Further, the source access network device acquires QoE context information of the terminal device, and sends the QoE context information to the target access network device.

Further, the target access network device generates an acquisition request based on the indication message, and sends the acquisition request to the source access network device.
