Patent ID: 8594026

Claim:
One or more nontransitory computer-readable media having computer-useable instructions embodied thereon for performing a method of discovering communications-network resources to facilitate preregistration of a mobile device that has a first radio and a second radio, each equipped to communicate with networks of a first wireless-communications technology and a second wireless-communications technology respectively, the method comprising: communicating, by way of the first radio, with a first communications network that employs the first wireless-communications technology; receiving, by way of the second radio, an indication that a second communications network is available to potentially service the mobile device, wherein the second communications network employs the second wireless-communications technology that is different from the first wireless-communications technology; sending, by way of the first radio and the first communications network, a preregistration request to a resource-allocation component associated with the second communications network, wherein the resource-allocation component allocates resources within the second communications network to service the mobile device via the second radio, wherein the second network services the mobile device without the mobile device separately registering with the second network; and communicating, by way of the second radio, through the second communications network without having to wait to register with the second communications network.
