D.1.1 Overview
Taught in 5. Finding your way around TS 24.501 (CT1 — the group that writes what your phone says, in depth), 4. Inside TS 24.501, the document at the centre (CT1 — the group that writes what your phone says, overview).
The UE provides the PCF with a list of one or more stored UE policy section identifiers (UPSIs) during the UE-initiated UE state indication procedure. The UPSI is composed of two parts:
- a PLMN ID part containing:
- the PLMN ID for the PLMN; or
- the PLMN ID part of the SNPN identity for the SNPN;
of the PCF which provides the UE policies; and
- a UE policy section code (UPSC) containing a value assigned by the PCF.
During the UE-initiated UE state indication procedure, the UE also provides the PCF with the UE policy related capabilities such as the UE's support for ANDSP, the UE's support for URSP provisioning in EPS, and the UE's OS Id.
During the network-requested UE policy management procedure, the PCF provides the UE with one or more UE policy sections containing UE policies. The UE processes the received UE policy sections, each identified by the UPSI, received from the PCF and informs the PCF of the result.
In the present annex, the condition that the PLMN ID part of the UPSI is referring to the HPLMN shall be considered as fulfilled only if the PLMN ID is equal to the HPLMN code derived from the IMSI.
NOTE: This is also applicable if the UE has a non-empty EHPLMN list, even if the EHPLMN list does not include the PLMN ID derived from the IMSI.
The UE can also request the PCF to provide V2XP as specified in 3GPP TS 24.587 [19B].
The UE can also request the PCF to provide ProSeP as specified in 3GPP TS 24.554 [19E].
The UE can also request the PCF to provide A2XP as specified in 3GPP TS 24.577 [60].
The UE can also request the PCF to provide RSLPP as specified in 3GPP TS 24.514 [62].
