Description
Technical field
The present invention relates to telephone network, especially relate to the realization of group-calling service in telephone network.
Background technology
Realize in honeycomb and the public switch telephone network that the scheduling group-calling service has had multiple implementation method, wherein change requires smaller some method to existing network.
At present existing a kind of implementation method, the scheduling controller that logically is positioned at the existing telephone network outside is coupled to existing telephone network.When the communicator that starts was wished to begin scheduling or grouied busy, the communicator that starts sent call request to existing telephone network, comprising the sign and the destination address relevant with scheduling controller of the device that starts.Existing telephone network provides call request to the scheduling controller of identification, and scheduling controller is dispatched relevant information according to the ID or the destination address of the device that starts from the database retrieval that is coupled to scheduling controller.The scheduling relevant information comprises the talk group subordinate relation of the communicator that starts.Scheduling relevant information according to retrieval, one group of target communication device of scheduling controller identification dispatch call, then, scheduling controller produces control signal and sends this control signal through existing telephone network to start communicator and reorganization target communication device and grouies busy to develop and manage.Set up in this way and group busy, permission will be dispatched group-calling service and will be added in the existing public telephone network as public switch telephone network and cellular radio network and so on, not need existing telephone network is improved.
Though this method can realize the scheduling group-calling service under the prerequisite of not transforming existing telephone network, the solution of initiating the group calling request from control desk (as computer) is not provided; Simultaneously, dispatching database and the scheduling controller of preserving schedule information are coupled, and when dispatch group belongs to non-service area, realize the group calling to this dispatch group like this, and dialing and route are all had a lot of restrictions.As, if when a service area is called out the group of another service area, can't from the local scheduling database, obtain the group information of purpose group, must before group number, increase extra routing iinformation, make this calling can be routed to purpose group place scheduling controller.In order to carry out group calling to the group in each service area, that just is necessary for each service area and distributes a special routing number, and in each physical entity of process, increases the analysis to these routing numbers in network, and is bigger to the existing network influence.
Summary of the invention
The object of the present invention is to provide a kind of method that realizes the system of group-calling service and realize group-calling service, do not changing under the existing network situation, provide the group calling function to existing network, the solution of initiating the group calling request from control desk is provided, and eliminates in the group calling that dispatch group belongs to non-service area restriction dialing and route.
