A method for judging cell resource release is disclosed. After a group call in a cell L begins and a channel resource is established, each judging process comprises the following steps of: (a) starting a pre-release checking stage, a system sending a forward checking signal to request terminals to report state information, and if the system does not receive a reverse signal related to the cell L in the checking time length of this checking stage, the system notifying other cells that the cell L prepares to release the channel resource, and proceeding to next step, otherwise, proceeding to a next judging process; after receiving the notification, the other cells notifying terminals within areas thereof that if planning to hand off to the cell L, a handoff request should be sent to the system; (b) starting a release checking stage, the system sending a forward checking signal to request the terminals to report the state information, and if the system does not receive a reverse signal related to the cell L in the checking time length of this checking stage, the system releasing the channel resource of the cell; otherwise, proceeding to a next judging process. The present invention can avoid the handoff failure and even drop-call of the terminals caused by the asynchrony of the signaling between the system and terminals.
