20080267152 | MULTIMEDIA BROADCAST/MULTICAST SERVICE (MBMS) SERVICE DISCOVERY - A system and method for discovery of and access to service in a Multimedia Broadcast/Multicast Service (MBMS) environment by user equipment (UE) when roaming. The UE may be associated with a plurality of URLs including a home URL and a symbolic URL. When the UE is roaming, the symbolic URL is resolved by a local DNS server to a local URL that is assessed by a local Service Discovery server to determine the MBMS services that may be accessed by the UE in the visiting network. Further, when roaming, the home URL is resolved by the local DNS server and forwarded to a home Service Discovery server where the home URL is assessed to determine the MBMS services that may be accessed by the UE in the home network. Accordingly, the UE is operable to access home network MBMS services as well as visiting network MBMS services when roaming. | 10-30-2008 |
