Feature Description
Presence Reporting Area (PRA) is an area defined within 3GPP packet domain for reporting UE presence within that area for policy control and/or charging reasons.
A Presence Reporting Area consists of:
-
TAs or eNBs and/or ECGI for E-UTRAN
-
RAs or SAIs or CGIs for UTRAN
-
RAs or CGIs for GERAN
The two types of Presence Reporting Areas that apply to an MME pool are UE-dedicated Presence Reporting Areas and Core Network pre-configured Presence Reporting Areas.
Note | cnSGW-C supports Core Network pre-configured PRAs in this release. |
The information for leveraging PRA for implementing differential charging and policy enforcement is provided in 3GPP TS 23.401.
The cnSGW supports:
-
Passing PRA action to MME as received from PGW in CSRsp, CBReq, UBreq, MBRsp, and CNRsp messages.
-
Passing PRA information to PGW if received from MME in CSReq, CBRsp, UBRsp, CNotf Req, and MBReq messages.
-
Always passing the message to PGW if PRA information is present in MBReq.
For more information, see Presence Reporting Area chapter in the UCC 5G cnSGWc Configuration and Administration Guide.
