Abstract
Apparatus and methods to reuse wireless circuitry to communicate with multiple wireless networks to support multiple subscriber identities in a wireless communication device are disclosed. A representative method includes receiving signaling messages for a second subscriber identity from a second wireless network while connected to a first wireless network for a first subscriber identity. A portion of radio frequency wireless circuitry is reconfigured to communicate with the second wireless network to establish a signaling channel and respond to signaling messages received from the second wireless network. The portion of radio frequency wireless circuitry is reconfigured between the first and second wireless networks to maintain a connection with the first wireless network while also receiving from the second wireless network limited information that can be provided to a user. Representative information includes an indication of an originator of a mobile terminated connection request and short message service data.
