Claim:
A method of avoiding hanging Packet Data Protocol (PDP) contexts in a General Packet Radio Service (GPRS) network, the method comprising: receiving in a Gateway GPRS Support Node (GGSN), a request message from a Serving GPRS Support Node (SGSN) to create a PDP context, the request message including a response time period; initiating creation of the PDP context by the GGSN in response to receiving the request message; when creation of the PDP context is completed before the response time period expires, sending a response message from the GGSN to the SGSN with a first cause value indicating the PDP context has been created, and including identifying information for the PDP context; and when creation of the PDP context is not completed before the response time period expires: aborting creation of the PDP context; and sending the response message from the GGSN to the SGSN with a second cause value indicating creation of the PDP context has been aborted.
