Abstract: front page image
(EN) The present invention relates to wireless communication technology for group call, and discloses a method for transmitting short data in group call in a wireless communication system, so that simultaneous transmission of voice and data in group call may be implemented. In the present invention, if an uplink channel is not occupied by any other subscriber device, the subscriber device which needs to transmit short data reports layer 3 information including the short data after occupying the uplink channel through request procedure, the network side device responds to the layer 3 information, broadcasts the short data on an FACCH or SACCH and releases the uplink channel. If the uplink channel is occupied by any other subscriber device, the subscriber device which needs to transmit short data is assigned a sub time slot of an SDCCH by the network side device through request procedure, and it reports layer 3 information including the short data through the sub time slot, the network side device responds to the layer 3 information, releases the sub time slot of the SDCCH and broadcasts the short data on a group call channel.
