PSC2 - Packet Services Card 2
The SGSN now supports the Packet Services Card 2 (PSC2), the next-generation packet
forwarding card for the ST40. The PSC2 provides increased aggregate throughput and
performance, and a higher number of subscriber sessions. For more information about this
card, refer to the “SGSN Overview” in the SGSN Administration Guide and the ST40
Hardware Installation and Administration Guide.

Suppression of Paging Cause IE in Paging Request
The CLI has been modified to allow the operator to configure suppression of the Paging
Cause IE in a Paging Request. As well, the operator has been given the ability to configure
the cause value for various paging sources.

For details, refer to the
ranap
command in the RNC Configuration Mode chapter of the
Command Line Interface Reference.
Tracking Usage of GPRS Encryption Algorithm
Usage of the GPRS encryption algorithm (GEA) significantly affects the SGSN processing
capacity depending upon the GEAx level used - GEA1, GEA2, or GEA3.
capacity depending upon the GEAx level used - GEA1, GEA2, or GEA3.
Operators could use a mechanism that would enable them to identify the percentages of
their customer base that are using the various GEA encryption algorithms. The same tool
would also track the migration trend from GEA2 to GEA3 and allow an operator to forecast
the need for additional SGSN capacity to exceed.

Enhanced counters should display the absolute number of attached subscribers using each of
the GEA algorithms.
the GEA algorithms.
Counters have been added to the output of the
show sub gprs-only summary
CLI
command to track:
●
the number of subscribers capable of GEA0-GEO3, and
●
the number of subscribers with negotiated GEAx levels.
New counters display the number of subscribers whose MS network capability supports
GEA0/GEA1/GEA2/GEA3. Similarly, the new counters under “Negotiated” indicate the
number of subscribers who have negotiated with the SGSN to use a specific encryption
algorithm according to the ciphering priority configuration and the network capability.
