In some embodiments, the PCF network element configures ProSe-related policies according to the data analysis result, which may include: configuring corresponding parameters in the ProSe Policy according to the data analysis result; and/or configuring the ProSe related parameters in URSP according to the data analysis result. Regarding how the PCF network element configures the corresponding parameters in ProSe Policy according to the data analysis result, the embodiments of the present disclosure do not limit, and the corresponding parameters in ProSe Policy may be configured according to a configuration mode predefined in the PCF network element.
The ProSe related parameter in URSP refers to a ProSe service related parameter among parameters included in URSP. In some embodiments, the ProSe-related parameters in URSP include ProSe layer-3UE-to-Network Relay Offload indication. Regarding how the PCF network element configures ProSe related parameters in URSP according to the data analysis result, the embodiments of the present disclosure are not limited, and may be configured according to a configuration manner predefined in the PCF network element.
In some embodiments, after the PCF network element configures the ProSe related policy according to the data analysis result, the configured ProSe related policy is sent to the UE. Wherein the UE may include at least one of a relay UE and a remote UE.
For example, when the remote UE is in a position with poor or no coverage of radio signals and satisfies the condition that ProSe service is available, the NWDAF network element predicts that the current time and place are better than the user experience of directly accessing to 5GS (5G system) by using ProSe data collected by the remote UE, and the PCF network element may configure ProSe layer-3 UE-to-Network Relay Offload indication in URSP according to the prediction result of the NWDAF network element and send URSP after configuration to the remote UE to instruct the remote UE to perform relay communication.
For another example, NWDAF network elements predict that the slice load accessed by relay UE in a certain period of time is higher through collected ProSe data, PCF network elements configure slice parameters in ProSe Policy according to the prediction result of NWDAF network elements, and send the configured ProSe Policy to remote UE to instruct the remote UE to access to the slice with smaller load.
In some embodiments, proSe related policies configured according to data analysis results and sent by the PCF network element to the relay UE and/or the remote UE may be used to instruct the relay UE and/or the remote UE to start ProSe service, and may also be used to update parameters in ProSe service in progress by the relay UE and/or the remote UE.
The technical scheme provided by the embodiment of the disclosure can avoid the need of pre-configuring the ProSe related strategy for the PCF network element when the PCF network element is deployed to a certain extent. In addition, the PCF configures the ProSe related strategy according to the data analysis result to consider the user experience, so that the configured ProSe related strategy can effectively improve the user experience after being executed. Further, the ProSe related strategy is configured according to the data analysis result, so that the flexibility of configuring the ProSe related strategy is improved. The occupation of resources such as slice load in the network is considered according to the ProSe related strategy generated by the ProSe data, so that the network resource utilization rate can be effectively improved after the configured ProSe related strategy is executed.
