Description

Background Art

[0002] In business scenarios related to data services such as perception and artificial intelligence (AI), the measurement data collected by the access network (for example, the radio access network, RAN) needs to be uploaded to the core network for processing and analysis to obtain the final data service results and open them to the perception service requester.

DSMF also needs to support the data service capability reporting function of DPF.

[0049] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0050] Figure 1 FIG. 1 is a schematic diagram showing an exemplary application system architecture to which the method for establishing a data transmission channel in the embodiment of the present disclosure can be applied.

[0051] In one embodiment of the present disclosure, the AF network element 101 sends a data service request to the SEF network element 102. The data service request may carry data service type, data service requirements, data service execution node information, etc. The data service request is used to request data service and data transmission.

[0052] In one embodiment of the present disclosure, the SEF network element 102 selects a suitable DSMF network element 103 according to information such as the data service area in the data service service requirement carried in the received data service request. The DSMF network element 103 then selects a suitable RAN device 110, eAMF network element 105 and DPF network element 107 according to the data service service type and data service service requirement carried in the data service request.
