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.
