Abstract
A method and system for avoiding hanging Packet Data Protocol (PDP) contexts in a General Packet Radio Service (GPRS) network. A time-out period is included in a request message to create a PDP context. The request message is transmitted from a first GPRS Support Node (GSN) to a second GSN. The second GSN receives the request message and transmits a response message to the first GSN. If the second GSN is unable to create the PDP context within the time-out period, the response message informs the first GSN that creation of the PDP context has been aborted. A Network Service Access Point Identifier (NSAPI) may be included in the response message so that the first GSN may request the second GSN to delete the request for creating the PDP context after a N3-T3 timeout of the first GSN has expired.
