METHOD FOR TRIGGERING GROUP INFORMATION SYNCHRONIZATION IN REAL TIME ON NETWORK SIDE IN CLUSTER COMMUNICATION SYSTEM

摘要

A method for triggering group information synchronization in real time on a network side in a cluster communication system is provided. The method includes the following steps: under a condition that a Dispatching Agent Client updates user information/group information successfully, the user/group identification information of this operation and the operation type information are sent to a Cluster Dispatching Server; after the Cluster Dispatching Server receives the user/group identification information and the operation type information, it requests a call identification from a Cluster Authentication Server; the Cluster Authentication Server generates a call identification in response to the request of the Cluster Dispatching Server, and sends the call identification to the Cluster Dispatching Server; the Cluster Dispatching Server initiates a call to a terminal by using the call identification; the Cluster Dispatching Server requests the updated group information/user information from the Cluster Authentication Server; the Cluster Authentication Server sends the updated group information/user information to the Cluster Dispatching Server in response to the request of the Cluster Dispatching Server; and the Cluster Dispatching Server sends the updated group information/user information to the terminal in order to assure the consistency of the group information/user information of the network side and the terminal side. The method insures the integrality and correctness of the group information of the terminal side.
