ABSTRACT:
In an access network which supports a mobile IP protocol, a packet data protocol context is opened at support node and a gateway node in order to establish a connection between a mobile node and a mobile IP foreign agent located at the gateway node. A mobile IP registration over the connection is initiated. The gateway node monitors whether the registration is successful or fails. The PDP context is deleted, if the registration irrecoverably fails. If the registration was unsuccessful but a retry could be successful, the PDP context may not deleted, but the registration is retried.
