Abstract
Abstract A network access sequence for a mobile node (MN) in one or more foreign domains (FD). A foreign domain sends (A 1 ) service advertisement messages (M 1 ), each of which comprises an identifier ( 41 ) of the message, network address information ( 43 ) and a detailed service offering ( 42 ). The mobile node stores (A 2 ) the detailed service offerings and selects one of them. Then it sends a service request message (M 2 ) to the foreign domain which sent the selected service offering ( 62 ). The service request indicates ( 55 ) the selected service offering ( 62 ) and the mobile node's credentials ( 54 ). The foreign domain conveys the credentials to the mobile node's home domain (HD) for authentication and authorization and checks (A 4 ) if the selected service offering ( 62 ) can be supported. Next the foreign domain (FD) allocates communication resources for supporting the selected service offering and indicates (M 9 ) to the mobile node the availability of the requested service.
