BACKGROUND OF THE INVENTION A trunking communication system was born in the 1970s. The earliest cluster communication system was an analog system. Digital cluster technology emerged globally in the mid-1990s, and a digital cluster network appeared in China in the late 1990s. Digital trunking communication technology has the advantages of high communication channel utilization and large system capacity, and thus has been widely used. The two main services of cluster technology are scheduling and group calling. The scheduling function of the cluster service refers to simultaneously initiating a call to a certain number of communication terminals, so that the communication terminals simultaneously participate in one call; the group call function of the cluster service refers to calling the group number on a communication terminal, and All communication terminals simultaneously call in a call, thereby achieving the effect of multiple people simultaneously talking. The above communication terminal may be a wired terminal or a wireless terminal. In a specific application, the cluster system frequently dynamically changes the information of a group in which a communication terminal is located, mainly in the group of adding a communication terminal to a group, deleting a communication terminal from a group, and modifying information of a group in which the communication terminal is located. Wait. Therefore, it is necessary to ensure the consistency between the group information stored on the communication terminal side of the cluster system and the group information of the corresponding communication terminal stored on the network side. The existing technology is triggered by the communication terminal side or the network side periodically updates the group information. The possible problem is: If the network side cannot trigger the information update in time after modifying the related information, the group call is initiated. The communication terminal cannot join the call immediately, resulting in loss of call information and inability to notify some communication terminals in real time. Therefore, it is necessary to provide a method for updating group information in real time to ensure consistency of group information on the network side and the communication terminal side. SUMMARY OF THE INVENTION The present invention provides a method for real-time triggering group information synchronization on a network side in a trunking communication system. When a group information is changed on the network side, the triggering of the real-time group information update is initiated to the terminal side, so that the terminal can Instantly obtain corresponding group information, overcoming network side and terminal side groups Information cannot be kept in sync in real time. A trunking communication system in accordance with an embodiment of the present invention includes a cluster scheduling subsystem, a base station subsystem, and a switching subsystem. The cluster scheduling subsystem includes a cluster scheduling server, a cluster authentication server, a dispatching station server, and a dispatching station client; the base station subsystem includes a base transceiver station, a base station controller, and a scheduling client; Includes mobile switching center, and home location register. Specifically, the method for real-time triggering group information synchronization by the network side in the trunking communication system according to the embodiment of the present invention includes the following steps: in the case that the scheduling station client successfully updates the user information/group information, the operation is performed. The user/group identification information and the operation type information are sent to the cluster scheduling server; after receiving the user/group identification information and the operation type information, the cluster scheduling server requests the call identification from the cluster authentication server; the cluster answering server responds to the cluster Scheduling the request of the server, generating a call identifier, and sending the call identifier to the cluster scheduling server; the cluster scheduling server uses the call identifier to initiate a call to the terminal; the cluster scheduling server requests the cluster authentication server for the updated group information/user information; The authentication server sends the updated group information/user information to the cluster scheduling server in response to the request of the cluster scheduling server; and the cluster scheduling server sends the updated group information/user information to the terminal to ensure the network side and Terminal side group information / User information consistency. The method for real-time triggering group information synchronization in the cluster communication system according to the embodiment of the present invention further includes the following steps: The cluster scheduling server determines whether the current operation is a group member adding operation, and if yes, and the group is in a call Then, the following steps are performed, otherwise the processing ends; the cluster scheduling server initiates authentication of the added group member to the cluster authentication server, and if the authentication is passed, the added group member is immediately added to the group call. The case where the dispatching station client updates the user information/group information includes one or more of the following situations: adding a member, deleting a member, modifying group information, and user information. The invention has the disadvantage that the consistency of all the group information on the terminal side and the consistency of all the group information corresponding to the network side and the terminal cannot be guaranteed in real time in the existing cluster system, and the user cannot be added to the call immediately after the group management. The phenomenon of lost call information adds a method for triggering group information update in real time, ensuring the integrity and correctness of the group information on the terminal side.
