Abstract
Systems and methods for routing pages to cellular phones (UE) not connected to a cellular network, but connected to a wireless local area network (I-WLAN), are disclosed. The system can route cellular pages to disconnected cellular devices using 3GPP AAA components, such as a Third Generation Partnership Project authentication, authorization, and accounting (3GPP AAA) server. The system can route pages via a home location register (HLR) connected to the I-WLAN or a mobile switching center (MSC) connected to the I-WLAN. The system can determine an appropriate MSC based on proximity of the MSC to the last known location of the UE, for example, or based on the MSC with the lowest utilization rates. The system can send a page to the UE via the I-WLAN instructing the UE to reconnect to the cellular network. The system can then send cellular data to the UE using the cellular network.
