[0153]

[0154] Step 2. After receiving the first perception request, the SF determines to perform network-assisted SL perception operations based on perception accuracy, policy configuration or its own implementation; optionally, when determining to perform the SL perception operation, the SF sends a second request such as a SL perception UE information acquisition request (such as Sensing check and device query for PC5) to the UDM, UDR or AMF, and the request is used to retrieve the first perception UE with SL perception capability in the target area; or, the SF determines the first perception UE with SL perception capability in the target area based on local configuration.

[0155] Optionally, if in step 1, the first perception request carries a SL perception indication or the ID of the first perception UE, the SF may determine to perform a network-assisted SL perception operation based on the SL perception indication or the ID of the first perception UE.

[0156] Step 3. Optionally, the UDR, UDM or AMF returns the first perception UE with SL perception capability in the target area, that is, the first perception UE ID, based on the received second request.

[0162] Step 6. After receiving the SL sensing request, the first sensing UE performs discovery and selection of the second sensing UE (such as SL sensing UE discovery).

[0163] Step 7. Optionally, the first perception UE requests to obtain the SL perception capability information of the second perception UE; the specific process may include: first, the first perception UE sends a SL perception capability request to the second perception UE; then, the second perception UE replies and carries the perception capability information of the SL perception UE to the first perception UE.

[0165] -SL perception capability information of the first perception UE;

[0166] -SL perception capability information of the second perception UE;

[0167] -The identification ID of the second perceiving UE.

[0168] For example, the SL perception response may be sent via the UL NAS Transport.

[0169] Step 9.AMF forwards the SL perception response to SF. For example, the SL perception response may be forwarded via Namf_communication_N1N2MessageNotify.

[0170] Step 10. Optionally, if the SL sensing response does not include the SL sensing capability information of the first sensing UE or the second sensing UE, or the SF does not have valid SL sensing capability information of the first or second sensing UE, the SF sends a first capability acquisition request (such as SL Sensing capability request) to the first sensing UE; optionally, the first capability acquisition request may include the identifier of the first sensing UE or the second sensing UE.

[0171] Step 11. After receiving the first capability acquisition request, the first sensing UE returns a SL sensing capability response (such as an SLSensing capability response), which carries at least the SL sensing capability information of the first sensing UE or the second sensing UE to the SF.

[0172] Step 12. The SF sends the first perception auxiliary information to the first perception UE;

[0173] Optionally, if the SF can interact with the second perception UE, the SF can send the first perception assistance information to the second perception UE.

[0174] Optionally, after obtaining the SL perception capability of the first perception UE or the second perception UE, SF can determine whether the network calculates the SL perception result mechanism or the perception UE calculates the SL perception result mechanism (such as the perception UE supports SL perception calculation) based on information such as the SL perception capability of the first perception UE or the second perception UE; and determine the SL perception method based on the perception accuracy and the SL perception capability of the first perception UE or the second perception UE.

[0175] Optionally, if the perception UE calculates the SL perception result mechanism, the SF may also send the second perception auxiliary information to the first perception UE or the second perception UE.

[0176] Step 13. Optionally, after receiving the first perception auxiliary information sent by the SF, the first perception UE can send the first perception auxiliary information to the second perception UE, that is, share the first perception auxiliary information with the second perception UE; the first perception UE and the second perception UE perform sending and receiving configuration of the SL perception signal according to the first perception auxiliary information.

[0177] Step 14. The SF sends a first request, such as a SL perception measurement information acquisition request, to the first perception UE to obtain SL perception measurement information, such as SL perception measurement data or SL perception results.

[0178] Optionally, if the SF can interact with the second perception UE, the SF can also send a first request, such as a SL perception measurement information acquisition request, to the second perception UE to obtain SL perception measurement information, such as SL perception measurement data or SL perception results.

[0179] Step 15. After receiving the above-mentioned SL perception measurement information acquisition request, the first perception UE or the second perception UE performs the SL perception operation between perception UEs to obtain SL perception measurement data.

[0180] Step 16. The first sensing UE or the second sensing UE returns the SL sensing measurement information (such as SL sensing measurement data or SL sensing result) to the SF.

[0181] Optionally, if the second perception auxiliary information is received in step 12, the first perception UE or the second perception UE may calculate the SL perception result according to the second perception auxiliary information and the SL perception measurement data.

[0182] Step 17. SF calculates the SL perception result based on the received SL perception measurement data; further, SF can derive the perception analysis result based on the SL perception result.

[0183] Step 18. The SF returns the SL sensing measurement data or SL sensing result to the first UE, AF or sensing client network element Sensing client NF.

For example, it may be absolute time information (such as Monday, 13:00-19:00) or relative time information (such as within the next month). The time information may include the start time, end time or duration, etc.

[0192] Step 2. Same as step 2 in the above embodiment 1, except that: SF sends a third request, such as a SL-aware UE information acquisition request, to UDM, UDR or AMF, which carries the first-aware UE ID, to request the SL-aware UE's information acquisition capability.
