摘要： Voice and/or image data packets are transferred by a packet handler between user stations in a GSM-type mobile communications system using a General Packet Radio Service (GPRS) data link. Control data for controlling a call is stored in a data store accessible by the packet handler. The control data identifies call participants and the identity of a participant who has currently seized the call. A mobile station capable of video conferencing is operable in a half-duplex video conferencing mode, in which intermittent transmission of video data is controlled by depression of a transmit button.

摘要： The invention relates to a transmission control method implemented by a station having at least one data frame to be transmitted via a wireless telecommunication network. In one aspect, the method comprises, at each selection round from a maximum number of selection rounds: a step of obtaining a value representative of either an authorization to transmit said frame, or of a prohibition to transmit said frame; and, when the value is representative of an authorization for transmission, transmitting an information signal in the network so as to indicate, to the other stations, that the station has obtained a value representative of an authorization for transmission. The transmission of the information signal is at least partially carried out during the transmission of a data frame in the network.
