METHOD, SERVER AND SYSTEM FOR MANAGING =PUSH-TO-TALK= SESSION

摘要

The inventive method, server and system for managing a session in a talkie walkie mode (= push to talk =) between a plurality of terminals each of which is provided with corresponding capacities for encoding and decoding voice/image signals. The session is connected to the plurality of terminals via a server through a first wireless telecommunications network to which the terminals are connected and a second network to which the server is connected. Said server comprises a data encoder/decoder. When a session is established upon request of a terminal, the transmitting terminal transmits data encoded according to an initial type of coding to one or several receiving terminals which are connected via the server. Afterwards, the server receiving data which are encoded according to an initial type of coding, processes said data according to the respective capacities of the receiving terminals in order to ensure the compatibility between data encoded according to an initial type of coding and data received by said receiving terminals, where applicable according to at least one type of coding similar to the initial type of coding. Afterwards, the server transmits processed data to the receiving terminals.
