One, QoE measurement

The QoE measurement is to measure the comprehensive subjective use experience of the user on the quality and performance (including the aspects of effectiveness, availability, etc.) of the service, that is, to measure the use experience of the user on the service application, so that the operator can comprehensively evaluate the quality and performance of the service according to the QoE measurement result, so that the operator can know the problem of the service according to the comprehensive evaluation result of the user on the service, and can adaptively adjust the communication network according to the problem of the service.

It should be noted that the QoE measurement includes: 1.1, signaling-based QoE measurement, and 1.2, management-based QoE measurement. The following are detailed below:

1.1 Signaling-based QoE measurement

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

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

S101, an Access (AS) layer of the terminal equipment sends capability information to a radio access network (NG-RAN) in the 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 for representing the capability of the terminal equipment with QoE measurement.

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

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

It is to be noted that the configured QoE measurement information may include a configured range of QoE measurement and parameter information of required QoE measurement.

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

The radio resource control information includes QoE measurement configuration parameters.

It should be noted that the radio resource control information is transmitted from 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 stratum of the terminal device.

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

And the mobile terminal command comprises QoE measurement configuration parameters.

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

In one possible implementation, the QoE measurement reconfiguration information further includes: service type information. The traffic type information corresponds to at least one unencapsulated QoE measurement parameter.

Example 1, the service type information included in the first indication information is streaming service (streaming service) or Virtual Reality (VR) service. In this case, the at least one unencapsulated QoE measurement parameter may include at least one of: average throughput (average throughput), buffer level (buffer level), playlist (play list).

Example 2, the service type information included in the first indication information is a Multimedia Broadcast Multicast Service (MBMS). In this case, the at least one unencapsulated QoE measurement parameter may include at least one of: error duration (repetition duration), jitter duration (jitter duration), buffering duration (buffering duration), initial buffering duration (initial buffering duration), content access/switch time (content access/switch time).

Example 3, the service type information included in the first indication information is a multi-thread synchronous call (MTSI) service. In this case, the at least one unencapsulated QoE measurement parameter may include at least one of: error duration (repetition duration), jitter duration (jitter duration), and bound-trip time (round-trip time).

And S703, the first access network equipment sends QoE measurement reconfiguration information to the terminal equipment. Correspondingly, the terminal device receives the QoE measurement reconfiguration information from the first access network device.

In a possible implementation manner, in a handover scenario based on a connection state, the QoE measurement reconfiguration information is carried in at least one of the following information: the first access network device sends Handover Request acknowledgement (i.e., Handover Request acknowledgement) information to the second access network device, and the second access network device sends radio resource control Reconfiguration (i.e., RRC Reconfiguration) information to the terminal device.

It should be noted that, when the terminal is in a connected state and a handover occurs on the Xn interface, the QoE measurement reconfiguration information is carried in at least one of the following information: the Handover Request acknowledgement information (i.e., the Handover Request acknowledgement in S303) sent by the first access network device to the second access network device, or the radio resource control reconfiguration complete information (i.e., the RRC reconfiguration complete in S304) sent by the second access network device to the terminal device.

Under the condition that the terminal is in a connected state and the NG interface is switched, the QoE measurement reconfiguration information is carried in at least one of the following items: the Handover Request acknowledgement information (i.e., the Handover Request acknowledgement in S404) sent by the first access network device to the core network device, or the Handover Command (i.e., the Handover Command in S405) sent by the core network device to the second access network device, or the radio resource control reconfiguration complete information (i.e., the RRC reconfiguration complete in S406) sent by the second access network device to the terminal device.

In the idle-state-based handover scenario, the QoE measurement reconfiguration information is carried in the radio resource control recovery information (i.e., the RRC Resume of S505) sent by the first access network device to the terminal device.

Illustratively, the radio resource control recovery information (RRC Resume) may be:

s704, the terminal device sends a QoE measurement report to the first access network device. Accordingly, the first access network device receives the QoE measurement report from the terminal device.

Wherein the QoE measurement report includes a measurement result of the at least one unencapsulated first QoE measurement parameter. The measurement results are unpackaged measurement results.

It should be noted that, the specific implementation process of the foregoing S704 is: and the APP layer of the terminal equipment determines the measurement result of the at least one unpackaged first QoE measurement parameter according to the at least one unpackaged first QoE measurement parameter in the QoE measurement reconfiguration information, and generates a QoE measurement report according to the measurement result of the at least one unpackaged first QoE measurement parameter. And the terminal equipment sends a QoE measurement report to the first access network equipment. Accordingly, the first access network device receives the QoE measurement report from the terminal device.

S705, the first access network device performs network optimization according to the measurement result of the at least one first QoE measurement parameter that is not encapsulated.

It should be noted that the measurement result is a measurement result directly recognizable by the first access network device. In this case, the first access network device may perform network optimization directly according to the measurement result without decoding the measurement result.

The technical scheme at least has the following beneficial effects: the application provides a network optimization method, which indicates that a terminal device has triggered a mobility management event moving from a second access network device to a first access network device when the first access network device receives handover request information from the second access network device. In the mobility scenario, the first access network device generates QoE measurement reconfiguration information including at least one first QoE measurement parameter that is not encapsulated, and sends the QoE measurement reconfiguration information to the terminal device. After the terminal device generates a QoE measurement report including a measurement result of at least one first non-encapsulated QoE measurement parameter (the measurement result is a non-encapsulated measurement result) according to the QoE measurement reconfiguration information, the QoE measurement report is sent to the access network device, so that the first access network device can directly optimize a network according to the non-encapsulated measurement result in the QoE measurement report without analyzing the QoE measurement report, and further simplify a process of performing network optimization on the first access network device (target access network device) based on the QoE measurement report in a mobility scenario.

It should be noted that at least one of the methods shown in fig. 7 is configured by the first access network device for encapsulating the first QoE measurement parameter. In one possible implementation manner, the handover request information further includes: in the case of at least one second non-encapsulated QoE measurement parameter, with reference to fig. 7, as shown in fig. 8, the method for the first access network device to determine at least one first encapsulated QoE measurement parameter further includes the following S801.

S801, in a case that the at least one non-encapsulated second QoE measurement parameter is the same as the at least one non-encapsulated first QoE measurement parameter, the first access network device uses the at least one non-encapsulated second QoE measurement parameter as the at least one non-encapsulated first QoE measurement parameter.

It should be noted that the first access network device receives at least one unencapsulated second QoE measurement parameter from the second access network device (i.e., the at least one unencapsulated second QoE measurement parameter is generated by the second access network device). The first access network device compares the at least one unencapsulated second QoE measurement parameter with the at least one unencapsulated first QoE measurement parameter, and if the at least one unencapsulated second QoE measurement parameter is the same as the at least one unencapsulated first QoE measurement parameter, the first access network device may use the at least one unencapsulated second QoE measurement parameter as the at least one unencapsulated first QoE measurement parameter, thereby omitting communication overhead of the first access network device for regenerating the at least one unencapsulated first QoE measurement parameter.

The technical scheme at least has the following beneficial effects: the application provides a network optimization method, if the switching request information further includes: the first access network device may determine whether the at least one unencapsulated second QoE measurement parameter is the same as the at least one unencapsulated first QoE measurement parameter. Under the condition that the at least one unencapsulated second QoE measurement parameter is the same as the at least one unencapsulated first QoE measurement parameter, the first access network device may directly use the at least one unencapsulated second QoE measurement parameter as the at least one unencapsulated first QoE measurement parameter without reconfiguring the at least one unencapsulated first QoE measurement parameter, and may directly use the at least one unencapsulated second QoE measurement parameter, so that a process of reconfiguring the at least one unencapsulated first QoE measurement parameter by the first access network device is omitted, and a process of performing network optimization by the first access network device (target access network device) in a mobility scenario based on a QoE measurement report is further simplified.

In a possible implementation manner, in a connection state-based switching scenario, with reference to fig. 7, as shown in fig. 9, the above S703 may be specifically determined through the following S901 to S902.

S901, in a connection state switching scene based on an Xn interface, first access network equipment sends QoE measurement reconfiguration information to terminal equipment through second access network equipment.

It should be noted that the specific implementation process of S901 can be understood with reference to fig. 3, and is not described herein again.

S902, under the connection state switching scene based on the NG interface, the first access network equipment sequentially sends QoE measurement reconfiguration information to the terminal equipment through the second access network equipment and an access and mobility management function (AMF).

It should be noted that, the specific implementation process of S902 can be understood with reference to fig. 3, and is not described herein again.

The technical scheme at least has the following beneficial effects: the application provides a network optimization method, wherein under different scenes, first access network equipment needs to send QoE measurement reconfiguration information to terminal equipment through different equipment. Namely, in a connection state switching scene based on an Xn interface, first access network equipment sends QoE measurement reconfiguration information to terminal equipment through second access network equipment; and under the connection state switching scene based on the NG interface, the first access network equipment sequentially sends QoE measurement reconfiguration information to the terminal equipment through the second access network equipment and an access and mobility management function (AMF). Therefore, the terminal equipment can receive the QoE measurement reconfiguration information, so that the subsequent terminal equipment can generate a QoE measurement report according to the QoE measurement reconfiguration information.

In a possible implementation manner, the QoE measurement reconfiguration information may be carried in a Handover Command (Handover Command) of Handover Request acknowledgement information (Handover Request acknowledgement). The QoE measurement reconfiguration information may also be carried in a Handover Command (Handover Command). The radio resource control Reconfiguration information (RRC Reconfiguration). The QoE measurement Reconfiguration information may also be carried in radio resource control Reconfiguration information (RRC Reconfiguration). Other configuration information (other configuration). The QoE measurement reconfiguration information may also be carried in measurement Report application Layer information (i.e., Meas Report App Layer) of other configuration information (other configuration).

Illustratively, the Handover Command (Handover Command) may be:

illustratively, the radio resource control Reconfiguration information (RRC Reconfiguration) may be:

The first field may be 1. In this case, the first field is used to indicate that M of the N unencapsulated QoE measurement parameters are measured.

In a possible implementation manner, when the first indication information further includes a second field, the second field includes N bytes, and the N bytes correspond to N unpackaged QoE measurement parameters.

And under the condition that the ith node value in the second field is a first preset value, the first indication information is used for indicating that the ith unencapsulated QoE measurement parameter in the N unencapsulated QoE measurement parameters is to be measured.

In the case that the ith node value in the second field is the second preset value, it may be indicated that the ith unencapsulated QoE measurement parameter of the N unencapsulated QoE measurement parameters does not need to be measured.

It should be noted that the first preset value may be 3. The second preset value may be 4.

In connection with example 1, as shown in table 1 below, the 1 st and 2 nd node values are 3. In this case, the first indication information is used to indicate that the 1 st and 2 nd un-encapsulated QoE measurement parameters (i.e., average Throughput, buffer level) in the 3 un-encapsulated QoE measurement parameters are measured.
