Abstract
Systems, methods, and software for controlling roaming of wireless communication devices onto wireless communication networks are provided herein. In one example, method of operating a wireless communication network is provided. The method includes, during a communication session initiation process between the wireless communication device and the roaming wireless communication network, receiving a request for policy information for the wireless communication device. Responsive to the request for the policy information, the method includes identifying a network address of a roaming gateway serving the wireless communication device and a paging tracking area identifier for the wireless communication device in the roaming wireless communication network. The method includes processing the network address and the paging tracking area identifier to determine a roaming authorization status for the communication session, and transferring the roaming authorization status for delivery to the roaming wireless communication system.
