摘要

A method for indicating a channel for sending an uplink access request, includes: ending an indication message indicating whether a group call channel uplink is available in a cell of a group call area; receiving an uplink access request via the group call channel uplink from a listener if the group call channel uplink is available according to the indication message; and receiving the uplink access request via an uplink channel from the listener if the group call channel uplink is unavailable according to the indication message. The solution of the present invention enables listeners to send uplink access requests when a talker is talking on the group call channel uplink.
