The invention relates to a method for cluster call distributing clients, which is used for cluster communication systems. The method for cluster call distributing clients comprises the steps as follows: step 1. a main control module of a base station controller distributes a resource distribution request to a resource management module of the base station controller after receiving a cluster callrequest; step 2. the resource management module of the base station controller selects cluster call distributing clients according to the loading of the cluster call distributing clients in the current base station controller and returns a selected result to the main control module of the base station controller; step 3. the main control module of the base station controller transmits a request for establishing cluster calls to the selected cluster call distributing clients according to the selected result; and step 4. the selected cluster call distributing clients initiate a request for establishing cluster calls towards a cluster call distributing server, which is used for starting the flows for establishing the cluster calls. By detecting the loading of a plurality of PDC subsystems inthe base station in real time, the traffic distribution of the cluster calls is determined, thus achieving the goal of accurately managing the PDCs in the same base station, improving the system capacity of the single base station and saving the development expenses.
