[0241] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0242] In the embodiments of the present disclosure, unless otherwise specified, elements expressed in the singular, such as "a", "an", "the", "above", "said", "the", "the", etc., may mean "one and only one", or "one or more", "at least one", etc. For example, when using articles such as "a", "an", "the" in English in translation, the noun following the article may be understood as a singular expression or a plural expression.

[0495] The following is an exemplary introduction to the above method.

[0496] This disclosure first proposes a new collaborative perception computing network architecture, which establishes data information collection, information storage, information calculation and processing, and information open network functions within the network. On the one hand, it can exchange control signaling with other NFs through the core network control plane, and on the other hand, it can transmit data with the UPF through the user plane. The 6G network architecture based on this design is shown in Figure 1B above. This network architecture retains the 5GS architecture and network functions to the greatest extent possible, and adds data information collection, information storage, information calculation and processing, and information open network functions on its basis, which are respectively used for information collection within the network, data storage, data calculation and processing, and output of inference results. Both the UE and RAN sides have perception functions, and terminal entities such as mobile phones and smart cars capture direction, speed, and vehicle driving information through antennas, cameras and other devices.

[0497] The present disclosure provides a user selection method for UE and network collaborative perception computing, the main purpose of which is to select a suitable UE to participate in collaborative perception computing based on the UE's location information, perception capability and AF constraints.

[0498] FIG10 is a flow chart of a terminal selection method according to an embodiment of the present disclosure. As shown in FIG10 , the method includes:

[0499] (1) The AF sends Nnef_AnalyticExposure_Subscribe to the DICF through the NEF. The parameters include: AF ID, UE ID list 1, and threshold conditions for UEs (UE location, network performance, UE QoS, UE perception capability, etc., as restriction conditions for screening UEs);

[0500] (2) DICF sends a Namf_EventExposure_Reqeust message to AMF, setting the event type to UE location information and UE perception capability.

[0501] (3) The AMF sends a UE_Ability_Request message to the UE through the RAN, requesting the UE to report its location information and sensing capabilities.

[0502] (4) The UE replies to the AMF with a UE_Ability_Response message, which includes the UE's location coordinate information and perception capability information, including perception area, perception accuracy, perception resolution, and perception latency.

[0503] (5) AMF responds with Namf_EventExposure_Response to DICF. DICF receives the UE location information and UE perception capabilities and filters UE ID list 2 from UE ID list 1.

[0504] (6) DICF sends an Npcf_EventExposure_Request message to PCF, requesting QoS monitoring information (uplink and downlink channel delay, communication rate) for UE ID List 1.

[0505] (7) PCF replies to DICF with an Npcf_EventExposure_Response message, which includes QoS monitoring information.

[0506] (8) The DICF sends the received location information, sensing capability information, QoS monitoring information, and threshold conditions for the UE passed by the AF to the DCP for processing and analysis.

[0507] (9) The DCP performs calculation and analysis based on the received information, filters UE ID list 1 to obtain UE ID list 3, and sends it to the DICF in the calculation and analysis result response.

[0508] (10) DICF filters UE ID list 4 based on the final analysis results and combines its own data collection capabilities, UE ID list 2, and UE ID list 3 to send it to DIEF.

[0509] (11) DIEF sends the final recommended UE ID list to AF through NEF.

[0510] (12) AF selects the UE based on the recommended list and subsequently updates the subscription to DICF based on the actual situation.
