Disclosed are a group resource release method, device and system. The method includes: an evolved Node B (eNB) determines, from group cells which belong to the eNB, a target cell which needs to release a group resource; and the eNB sends to the target cell a message for instructing to release the group resource, wherein the message for instructing to release the group resource is used for instructing the target cell to release an air interface resource of the target cell and/or a group resource which is allocated to the target cell by the eNB. It is solved by the embodiment of the disclosure the problems that the release speed is slow and the utilization rate of group call resources in a trunking group call is low, thus effectively improving the utilization rate of the group call resources in the group call.
