context: on SLPBK-ID. If they are with the same HPLMN, skip steps 10~12. Otherwise, the serving SLPKMF of UE-x should send a key query request to the serving SLPKMF of UE-1 based on SLPBK-ID. 10) The serving SLPKMF of UE-x sends a key query request to the serving SLPKMF of UE-1, with SLPBK-ID and encrypted UE-1-ID. 11) The serving SLPKMF of UE-1 checks whether to return the key based on local policy. If checked, go to step 12. 12) The serving SLPKMF of UE-1 decrypts the encrypted UE-1-ID, determines SLPPK of UE-1 chosen in step 5. The serving SLPKMF of UE-1 returns the key query response to the serving SLPKMF of UE-x, including SLPBK, UE-1's SLPPK, SLAPP-ID, and key expiration time. 13) The serving SLPKMF of UE-x identifies the SL positioning service and the corresponding ranging/SL application server according to the received SLAPP-ID. It sends SL broadcast receiving authorization request which includes UE-x-ID to the ranging/SL application server to authorize UE-x to receive broadcast
description: The SideLink Positioning Key Management Function (SLPKMF) is a network function responsible for managing and distributing keys related to sidelink positioning services. It handles key queries, returns key query responses, and authorizes user equipment to receive broadcast messages.
explanation: SLPKMF is classified as a Network Function because it performs specific tasks within the network infrastructure, such as managing and distributing keys essential for sidelink positioning services. Its interactions with other network components and its role in authorizing user equipment highlight its function as a distinct part of the network.
