The network is not having only one GGSN, it may have a few GGSNs. Also, it is having a lot

The MS, the SGSN, and the GGSN can initiate The ‘PDP context deactivation procedure’. PDP Context Deactivation Procedure (MS initiated)

In case one of any parameters associated with the PDP context changed, like the QoS as example. The node in

NSAPI NSAPI refers to ‘Network layer Service Access Point Identifier’. The MS generates the NSAPI in the ‘PDP context activation’ procedure,

QoS refers to ‘Quality of Service’. After ‘PDP context activation’ procedure completes, a ‘PDP context’ shall exist on the MS,

PDP type is the type of the IP address assigned to the PDP. PDP type maybe one of the following,

As a result of the ‘PDP activation’ procedure, the GGSN assigns the ‘PDP context’ an IP address. The ‘PDP address’
