摘要： A method for transmitting short data during group call in wireless communication system. The present invention enables synchronous transmission voice and data during group call. In the present invention, when up channel isn't occupied by other user devices, the user device that requires transmission short data occupies the up channel through applying. Then the user device reports layer 3 information that includes short data. Network side device responds the layer 3 information and broadcasts the short data on FACCH and SACCH channel, then releases the occupying of up channel. If up channel has been occupied by other user devices, the user device that requires transmission short data is assigned one subtimeslot of SDCCH by network side device through applying. The user device reports layer 3 information that includes short data by the subtimeslot. Network side device responds the layer 3 information and releases the occupying of SDCCH, and broadcasts the short data on group call channel.
