Method and system for avoiding hanging pdp contexts

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.

A Gateway GPRS Service Node (GGSN) configured to avoid hanging Packet Data Protocol (PDP) contexts in a General Packet Radio Service network, the GGSN including a processor coupled to a non-transitory computer-readable medium for storing computer program instructions, wherein when the processor executes the computer program instructions, the GGSN is caused to:

• receive a request message from a Serving GPRS Support Node (SGSN) to create a PDP context, the request message including a response time period;
• initiate creation of the PDP context in response to receiving the request message;
• when creation of the PDP context is completed before the response time period expires, send 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:
• abort creation of the PDP context;
• and
• send the response message from the GGSN to the SGSN with a second cause value indicating creation of the PDP context has been aborted.

A method of avoiding hanging Packet Data Protocol (PDP) contexts in a General Packet Radio Service (GPRS) network, the method comprising:

• sending a request message from a Serving GPRS Support Node (SGSN) to a Gateway GPRS Support Node (GGSN) to create a PDP context;
• receiving by the SGSN, a response message from the GGSN after expiration of a N3-T3 time-out period associated with the SGSN, the response message indicating the PDP context has been created, and including a Network Service Access Point Identifier (NSAPI);
• and
• utilizing the NSAPI by the SGSN to send a delete request to the GGSN to remove the PDP context in the GGSN.
