Abstract: 本发明公开了一种组呼或广播呼叫接续的控制方法、装置及系统。其中，该组呼或广播呼叫接续的控制方法包括：控制实体根据各个终端在组呼或广播呼叫中的特性，为各个终端设置听权限和说权限；控制实体将各个终端的听权限和说权限发送给媒体网关；媒体网关根据各个终端的听权限和说权限对各个终端进行接续处理。通过本发明，可以简化集群通信中组呼或广播呼叫的接续，提高控制实体和媒体网关的处理效率。

Abstract: A method and a device for adjusting the relay state are provided, wherein the method includes that if a media gateway controller receives a request for new service and thus uses a relay circuit, then it sends an adding command message to a media gateway; after receiving the adding command message, the media gateway checks that the relay circuit is unavailable and could not implement the process for the adding command message successfully; the media gateway sends to the media gateway controller an error response message and a state report message indicating that the relay circuit is unavailable; and after receiving the state report message, the media gateway controller modifies its state information on the relay circuit based on the state report message and returns a response message to the media gateway. As a result, based on the H.248/Megaco protocol, the invention solves the phenomenon of the relay circuit states inconsistent wherein the MGC considers a relay circuit state as normal while the MGW considers the relay circuit state as abnormal, and the invention could deal with this phenomenon quickly and simply, therefore the call loss could be reduced.
