Abstract: A system and method for an improved two-way packet-centric like radio communication network that transmits signals and data over Internet Protocol. The improved like radio communications network provides advanced features and enhanced services to its users, such as the capability of roaming across a plurality of similar like radio communications networks. A plurality of client devices including an enhanced client application for the operation of two-way like radio networks that accesses, contacts, and communicates with one or more client devices of the same network or one or more client devices of different like radio networks. The radio network includes an optional server application to establish packet-based radio communications between at least two client devices within a single radio network or across a plurality of radio networks.

Abstract: In a communication network a method and system for integrating data and voice services into a single session. Subscribers in a wireless communication network are communicatively linked to information sources in a data network via a gateway. The subscribers submit requests to voice service providers in the data network. A data and voice switching server effects integration of the data and voice services within the current session by suspending the data session, opening an integrated voice and data session and maintaining the integrated session by controlling and coordinating the functionality of an access provider switch, a gateway server, a remote access server, and a voice server. Subscribers are provided integrated voice and data services within a single session. After the completion of the voice services the subscribers transparently reconnected to the data network by the voice and data switching server.
