Notes:
The least or most restrictive values of the APN restriction are applicable only for the Gn SGSN, as the APN
restriction can be present in UPCQ/UPCR for Gn SGSN and this configuration is required to determine the
PDN to be de-activated when an APN restriction violation occurs during modification procedures in the Gn
SGSN.
PDN to be de-activated when an APN restriction violation occurs during modification procedures in the Gn
SGSN.
In the case of S4-SGSN, the APN restriction arrives at the S4-SGSN only in Create Session Request Response
during activation. During activation in S4-SGSN, a PDN connection that violates the current Maximum APN
restriction is always de-activated. Therefore in the case of S4-SGSN, this CLI is used only for enabling or
disabling APN restriction.

CSCty82285 - Increasing Lawful interception capacity on SGSN
Feature Changes
Lawful Interception Capacity Enhanced
In a full ASR5K chassis with PSC2 cards the maximum number of attached users is about “4” million. In previous
releases, it was possible to configure and intercept 20000 camp-on users on the chassis. With this feature enhancement
the lawful interception capacity has been increased to 4% of the maximum number of attached users, that is 160,000
camp-on users (4% of 4 million subscribers). It is now possible to configure and intercept 160000 camp-on users on the
chassis.

Previous Behavior: The lawful interception capacity is limited to 20000 intercepts.
