CSCty44479 - APN Restriction on S4-SGSN
Feature Changes
APN Restriction Extended to S4-SGSN
Previous Behavior: The Gn-SGSN supports the APN Restriction feature.
New Behavior: Support for APN Restriction is required on the S4-SGSN. The reception, storage, and transfer of APN
Restriction values is used to determine whether a UE is allowed to establish PDP Context or EPS bearers with other
APNs.
Restriction values is used to determine whether a UE is allowed to establish PDP Context or EPS bearers with other
APNs.
During default bearer activation, the S4-SGSN sends the current maximum APN restriction value for the UE to the P-
GW in a Create Session Request (CSR). The P-GW retains an APN restriction value for each APN. The UE’s APN
Restriction value determines the type of application data the subscriber is allowed to send. If the maximum APN
restriction of the UE (received in the CSR) and the APN Restriction value of the APN (for which activation is being
request) do not concur, then the P-GW rejects activation. The maximum APN restriction for a UE is the most restrictive
based on all already active default EPS bearers.

APN Restriction for S4-SGSN is enabled/disabled in the call-control-profile configuration using the existing
apn-
restriction
command -- this command also enables APN Restriction for the Gn-SGSN. This feature provides the
operator with increased control to restrict certain APNs to UEs based on the type of APN. This feature requires no
special license other than the S3/S4 license needed to enable the S4-SGSN.
