Abstract: A third generation (3G) gateway (30) provides the facilities for extending a number of internet protocols between a second generation (2G) network and a 3G network as shown in Figure 1. The various messages of session initiation protocol (SIP) are extended to provide user identification and server identification subfields . The SIP message extensions facilitate the communication of 2G and 3G networks for the purposes of implementing push-to-talk and dispatch service features.

Abstract: These teachings facilitate interaction between two or more communication networks (10 and 11) comprising separate and discrete communication system peers. At least one of these networks is functionally partitioned with respect to interrogation and call signaling procedures over a plurality of geographic service areas (14, 15, and 16). Gateways (12 and 13) permit interaction between these networks, wherein at least some of the gateways provide functionally partitioned interrogation and call signaling procedures for some, but not all, of the plurality of geographic service areas. Upon receiving (32) a call routing message from a source from a remote communication network, which message identifies a target communication unit that is currently serviced by the first communication network, such a gateway can process (33) that call routing message as a function, at least in part, of a home geographic service area and a serving geographic area as corresponds to the target communication unit.

Abstract: For a network server (35) communicating with a wireless unit (10) via a Session Initiation Protocol, a retransmission method (50) first sets a timer based upon a time likely for a mobile unit to respond (54). Then the network server waits for a response (56). When the timer set for the kind of mobile unit being used expires (64), a retransmit of the original SIP request takes place (68). Optionally, modes for waiting may include a linear mode (72) and an exponential mode (74).
