Abstract (en)
[origin: WO2012104725A2] The present solution is directed to a system for seamlessly communicating among a plurality of mobile devices comprising a private mobile radio module. The system includes a plurality of mobile devices establishing a group. Each of the plurality of mobile devices comprises a cellular communications module and a private mobile radio module to communicate with other mobile devices in the group using private radio communications. A mobile device of the group in audio communications with one or more mobile devices of the group using private radio communications via the private mobile radio module. A roaming manager of each of the plurality of mobile devices determines that the mobile device is no longer in communication via the private mobile radio module and responsive to the roaming manager, the private mobile radio module is deactivated and the cellular communications module is activated. Each of the plurality of mobile devices of the group establishes a connection with the server using their cellular communications module, the server providing audio communications for the group.
