Cisco Cisco ASR 5000
Support for RAT/Frequency Selection Priority ID (RFSP-ID)
How it Works ▀
SGSN Administration Guide, StarOS Release 18 ▄
When a SGSN receives the Context request in GTPv1 format, the SGSN Context response is sent back to the
sender SGSN in GTPv1 format with RFSP Id encoded as per the 3GPP TS 29.060 (Release 8, Version 8.16.0,
Section 7.7.88) in mm-context.

Inter-SRNS New SGSN
When a Gn/Gp-SGSN receives a Forwards Relocation Request from the Old SGSN as a result of the SRNS
Re-location Procedure, it decodes the RFSP ID from the GTPv1 formatted message and applies overriding
policy before saving it in the mm-context.

When a S4-SGSN receives Forwards Re-location Request from an Old Gn/Gp SGSN as a result of SRNS Re-
