ABSTRACT:
Systems and methods are disclosed for selecting a preferred foreign wireless network from a plurality foreign wireless networks. One embodiment of the invention comprises a home wireless network that includes an HLR and a managed roaming system coupled between the HLR and a plurality of foreign wireless networks. The managed roaming system receives registration messages for roaming subscribers being transmitted from the foreign wireless networks to the HLR. The managed roaming system monitors the number of registration messages received from the foreign wireless networks and forwards the registration messages to the HLR. The managed roaming system selects a preferred foreign wireless network based on the number of registration messages received from the foreign wireless networks over a time period. The managed roaming system then forwards subsequent registration messages from the preferred foreign wireless network to the HLR, and blocks registration messages from non-preferred foreign wireless networks.
