ACCESS CONTEXT MANAGEMENT FOR MACRO-LEVEL MOBILITY MANAGEMENT REGISTRATION IN AN ACCESS NETWORK

In an access network which supports a mobile IP protocol, a packet data protocol (PDP) context is opened at support node (SGSN) and a gateway node (GGSN) in order to establish a connection between a mobile node (MS/MN) and a mobile IP foreign agent (FA) located at the gateway node. A mobile IP regis...

Zusammenfassung:	In an access network which supports a mobile IP protocol, a packet data protocol (PDP) context is opened at support node (SGSN) and a gateway node (GGSN) in order to establish a connection between a mobile node (MS/MN) and a mobile IP foreign agent (FA) located at the gateway node. A mobile IP registration over the connection is initiated. The gateway node (GGSN) monitors (15) whether the registration is successful or fails. The PDP context is deleted (16 to 18), if the registration irrecoverably fails. If the registration was unsuccessful but a retry could be successful (the first failure was due to a load situation, for example), the PDP context may not deleted, but the registration is retried.
