Problems solved by technology

[0003] If the data analysis results generated by the data analysis network element are not timely, it will affect the network equipment in the wireless communication system to make correct decisions based on the data analysis results. For example, the data analysis network element can analyze the service experience of a certain service. , the data analysis network element sends the data analysis result to the policy control function (PCF) network element, and the PCF network element can adjust the service quality (quality of service, QoS) parameter corresponding to the service according to the service experience, but if the data analysis network element is too If the data analysis results are provided to PCF late, the service experience of the service may have changed. At this time, PCF adjusts the QoS parameters according to the non-real-time service experience, which obviously does not meet the service requirements.

Embodiment 1

[0295] Such as Figure 11 As shown, it mainly includes the following processes:

[0296] S00. The NWDAF that supports real-time data analysis triggers data analysis based on the analytics ID (Analytics ID). For example, the trigger condition for triggering data analysis can be that NWDAF obtains the model from the training platform and deploys it locally. For example, the model refers to a machine learning model, such as a service experience model (service experience model or service mean opinion score (MOS) model), which can represent service experience and network parameters (QoS flow bit rate or QoS flow latency). Corresponding relationship, NWDAF uses the above model and knows the network parameter value of a certain service flow, so it can evaluate the service experience.

[0297]It should be noted that there can be one or more NWDAFs supporting the analysis of the same Analytics ID. Different NWDAFs support different hardware capabilities and different NWDAF deployment...

Embodiment 2

[0316] Such as Figure 13 As shown, it mainly includes the following processes:

[0317] S10-S12. Same as S00-S02 in Embodiment 1.

[0318] S13. The NWDAF triggers the NRF network element registration request / response service Nnrf_NFManagement_NFRegister_Request / Rsp to the NRF.

[0319] Compared with Embodiment 1, in the process of registering with NRF, NWDAF only instructs NRF that the NWDAF supports data analysis within a specified delay for a certain Analytics ID, but does not inform NRF of the supported analytics delay. . Among them, the specified delay can be the delay threshold or delay interval configured inside NWDAF, for example, it is greater than or equal to the data analysis delay X, and is less than or equal to the data analysis delay Y. Only when the delay threshold or delay interval is met, Only then will NWDAF send indication information to NRF.

[0320] S14. The Consumer NF triggers the NRF network element discovery request / response service Nnrf_NFDiscover...

Embodiment 3

[0328] Both Embodiment 1 and Embodiment 2 are based on the integration of data management inside the NWDAF. In Embodiment 3, DCCF is introduced to assist in efficient data collection for the deployment of multiple NWDAFs.

[0329] Such as Figure 14 As shown, it mainly includes the following processes:

[0330] S20. Same as S00 in Embodiment 1.

[0331] S21.NWDA collects training data, mainly including:

[0332] S21a. The NWDAF triggers the DCCF event capability exposure subscription service Ndccf_EventExposure_Subscribe to the DCCF, and requests data from the DCCF.

[0333] S21b. The DCCF triggers the NF event capability open subscription / notification service Nnf_EventExposure_Subscribe / Nnf_EventExposure_Notify to the NF to request data from the NF. Then, the NF triggers the NF event capability exposure notification service Nnf_EventExposure_Notify of the DCCF, and sends data to the DCCF, where the service includes collected data, data preparation delay on the NF, data pre...

Abstract

The embodiment of the invention discloses a communication method, a communication device and system, which are used for enabling a data analysis network element to determine the time delay of data analysis and enabling a network element using a data analysis result to pre-judge the time delay requirement which can be met by the data analysis network element in advance. The communication method comprises: a data analysis network element sends a first request to a storage function network element, the first request comprising time delay information and / or indication information, the time delay information comprising one or more of the following information: collection time delay of first data, reasoning time delay of a data analysis result of the first data, and transmission time delay of the data analysis result, wherein the indication information is used for indicating that the data analysis network element supports data analysis within a specified time delay; the first request is used for storing time delay information and / or indication information to a storage function network element; and the data analysis network element receives a first response from the storage function network element, wherein the first response is used for indicating that the time delay information and / or indicating that the information is successfully stored to the data analysis network element.
