Patent ID: 8189548

Claim:
In a wireless telecommunications system communicating with multiple mobile devices, wherein the wireless telecommunications system includes a converged telecommunications network that employs a core telecommunications network, a cellular broadcast network and an IP-based broadcast network, and wherein subscribers can access the IP-based broadcast network via wireless connections between mobile devices and wireless access points forming IP-based wireless local area networks (WLANs), a method performed by the core telecommunications network to authorize access of a mobile device to services of the core telecommunications network, the method comprising: receiving a registration message from the mobile device at a network controlling node that facilitates communication between the core telecommunications network and the IP-based broadcast network, wherein the registration message includes information indicating that the mobile device is communicating with the IP-based broadcast network; determining from content included in the received registration message that the mobile device is capable of communicating with the core telecommunications network via the IP-based access network; and upon determining that the mobile device is capable of communicating with the core telecommunications network via the IP-based broadcast network: searching for information in a database of mobile devices authorized to communicate over the core telecommunications network, wherein searching for information includes searching for information that indicates that the mobile device is associated with a subscriber of services provided via the IP-based broadcast network but not services provided via the cellular broadcast network; determining, based on the indication, that the mobile device is associated with a subscriber of services provided via the IP-based broadcast network, but not a subscriber to services provided via the cellular broadcast network; and permitting the mobile device to only receive services via the IP-based broadcast network, but not to receive services via the cellular broadcast network.
