Abstract: The invention concerns a method (200) and system (100) for managing communications for a multi-mode communications device (130). The method can include the steps of establishing (210) communications with at least a first wireless network (110) and advising (216) the first wireless network of the multi-mode nature of the multi-mode communications device. As such, the first wireless network can be made aware that the multi-mode communications device is capable of communicating with a second wireless network (120).

Abstract: A system (20) and method (50) of establishing a rapid push-to-send data exchange in a multi-wireless network environment can include a first wireless network (24 and 26) having a fast network channel to exchange an Internet Protocol (IP) address or other data, a second wireless network (23 and 27) operatively coupled to the first wireless network having a high bandwidth data channel to exchange data using the IP address in a wireless peer to peer data transfer, and a communication protocol. The first wireless network can be an iDEN network and the second wireless network can be a CDMA network. The communication protocol can relinquish (66) communication using the first wireless network once a dedicated data channel on the second wireless network is established. The communication protocol can also simultaneously transfer (56) voice traffic on the first network when the first network is exchanging the IP address.

Abstract: A system (20) of establishing a rapid PTT call setup in a multi-wireless network environment, can include a first wireless network (24 and 26) such as an iDEN network optimized for rapid push-to-talk call setups in typically less than one second and a second wireless network (23 and 27) such as a CDMA wireless network operatively coupled to the first wireless network. The system can further include a communication protocol among an originating mobile subscriber unit (22), a target mobile subscriber unit (28), the first wireless network, and the second wireless network, where the first wireless network and the second wireless network receive a request for a PTT session and the PTT session is set up on the second wireless network using the first wireless network. The system can further include a PTT server (25) operatively coupled to the first wireless network and the second wireless network.
