A method and a system for transmitting application data in a trunk group are provided by the present invention. The method includes sending, by a talker or a listener, application data to network side of a wireless communication system, wherein the application data from the talker is transmitted via a dedicated channel uplink occupied by the talker, and the application data from the listener is transmitted via a group call channel uplink of a trunk group; receiving, by the network side of the wireless communication system, the application data sent from the talker or the listener, and broadcasting the application data in the trunk group. According to the method and system provided by the embodiments of the present invention, application data transmission can be implemented in the trunk group in which 1.5 uplink access mode is adopted and PTT takeover is allowed, and therefore synchronous transmission of data and voice can be realized.
L'invention concerne un procédé et un système pour envoyer des SMD dans un faisceau de lignes. Le procédé comporte les étapes suivantes: un appelant envoie un SMD vers un réseau de communication sans fil sur la voie privée utilisée par l'appelant; un appelé envoie un SMD vers un réseau de communication sans fil sur la voie d'appel à faisceau de lignes correspondant à une cellule; le réseau du système de communication diffuse le SMD après réception du SMD envoyé par l'appelant ou l'appelé. Le procédé et le système décrits, qui peuvent être mis en oeuvre sur une voie montante de type 1,5, permettent d'envoyer le SMD dans le faisceau de lignes utilisé par des transmissions PTT et de produire une transmission vocale synchrone.
