Abstract
A method and system for avoiding hanging Packet Data Protocol contexts in a General Packet Radio Service network. A time-out period is included in a request message (120) to create a Packet Data Protocol context. The request message (120) is transmitted from a first General Packet Radio Service Support Node (110) to a second General Packet Radio Service Support Node (130). The second General Packet Radio Service Support Node (130) receives the request message (120) and transmits a response message (140) to the first General Packet Radio Service Support Node (110). If the second General Packet Radio Service Support Node (130) is unable to create the Packet Data Protocol context within the time-out period the response message (140) informs the first General Packet Radio Service Support Node (110) that creation of the Packet Data Protocol context has been aborted. A Network Service Access Point Identifier may be included in the response message (140) so that the first General Packet Radio Service Support Node (110) may request the second General Packet Radio Service Support Node (130) to delete the request for creating the Packet Data Protocol context after a N3-T3 timeout of the first General Packet Radio Service Support Node (110) has expired.
