Abstract
A network access sequence for a mobile node (MN) in one or more foreign domains (FD). A foreign domain sends (A1) service advertisement messages (M1), each of which comprises an identifier (41) of the message, network address information (43) and a detailed service offering (42). The mobile node stores (A2) the detailed service offerings and selects one of them. Then it sends a service request message (M2) 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 (A4) 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 (M9) to the mobile node the availability of the requested service.
