Abstract:
1. In a hybrid wireless communication device, a method comprising: the hybrid wireless communication device acquiring a first protocol radio link on a first carrier frequency; the hybrid wireless communication device engaging in packet-based session setup signaling with a server via the first protocol radio link, to set up a packet-based real-time media session with the server; the hybrid wireless communication device detecting completion of the packet-based session setup signaling; responsive to detecting the completion of the packet-based session setup signaling, the hybrid wireless communication device automatically acquiring a second protocol radio link on a second carrier frequency, wherein the second protocol radio link is different from the first protocol radio link; via the second protocol radio link, the hybrid wireless communication device engaging in the packet-based real-time media session with the server; and upon completion of the packet-based real-time media session, the hybrid wireless communication device automatically transitioning to the first protocol radio link, so as to be prepared to once again use the first protocol radio link to engage in packet-based session setup signaling with the server.
