Policy-based roaming control for wireless communication devices
First Claim
1. A method of operating a wireless communication network to authorize roaming communications of a wireless communication device onto a roaming wireless communication network, the method comprising:
- 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, identifying a network address of a gateway serving the wireless communication device and a paging tracking area identifier for the wireless communication device in the roaming wireless communication network;
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.

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.
