Abstract  Abstract

The present invention discloses a method of uplink preemption by UEs later entering a trunking group with an established group call. With different priorities assigned for the UEs in the trunking group the method includes: after the uplink of the trunking group with an establish group call is occupied by a talker the trunking group sends a message with the priority information of the talker to the listeners; the later entry UE determines according to the received message with the priority information of the talker whether its own configured priority is higher than that of the talker if it is higher than that of the talker it determines that preemption for the uplink can be made; otherwise it demodulates the group call channel downlink assigned for the trunking group when the group call was established and listens to the voice. The method makes it possible for the later entry UE in a trunking group with an established group call to send an uplink access request and preempt the uplink when the UE has a higher priority.
