Abstract
A system and method for wirelessly communicating over two wireless networks having different communication protocols using a single transceiver of a vehicle telematics unit. The method includes monitoring a first network for an incoming page using a transceiver and a first network access device (NAD); the transceiver and the first NAD may be components of a cellular device, such as a vehicle telematics unit. The method includes monitoring a second network for another incoming page using the same transceiver and a second NAD. The second NAD also may be a component of the cellular device. When a page is received over the second network, a call may be connected using the second NAD, and the first network may be periodically monitored for an incoming page without disconnecting the call of the second network.
