Attach Rate Throttle
It is unlikely that the SGSN would become a bottleneck because of the SGSN‘s high signaling rates. However, other
nodes in the network may not scale commensurately. To provide network overload protection, the SGSN provides a
mechanism to control the number of attaches occurring through it on a per second basis.

Ga Interface to the CGF/GSS
The SGSN now supports the Ga interface to the CGF or GSS for accounting purposes.
The SGSN uses the Ga interface to communicate with the Charging Gateway Function (CGF) or GTPP Storage Server
(GSS) using GTP Prime (GTPP). The charging gateway is responsible for buffering and pre-processing billing records.
One or more Ga interfaces can be configured per system context. This interface is supported through the following
commands in the Context configuration mode:
