Estimating the term…
A method, a server and a system for managing a session in walkie-talkie (“push-to-talk”) mode between terminals each of which has respective capacities for encoding and decoding voice and/or image signals. The terminals are logged onto the session via a server and a first wireless telecommunications network to which the terminals are connected and a second network to which the server is connected. The server comprises a data encoder/decoder. When a session is established at the request of a terminal, a sender terminal sends data encoded according to an initial type of coding to one or more receiver terminals that are connected via the server. The server receiving data encoded according to the initial type of coding then processes the data according to the respective capacities of the receiver terminals in order to ensure compatibility of the data encoded according to the initial type of coding and the data received by the receiver terminals, where applicable according to at least one type of coding other than the initial type of coding. The server then sends the processed data to the receiver terminals.
A method of managing a walkie-talkie (“push-to-talk”) mode session between a plurality of terminals having respective data coding and decoding capacities, said session connecting the plurality of terminals via a walkie-talkie mode session management server and at least one telecommunications network, in which method, after a session has been established:
A data stream sent by a terminal to a server for managing sessions in walkie-talkie mode, said stream supporting a message defined by a particular signaling protocol and having the function of logging the terminal onto a session in walkie-talkie mode, characterized in that said message contains the coding and decoding capacities of said terminal.
