Abstract
The invention provides a method for realizing signaling interaction between a base station and a control center in a digital clustering system. The method comprises the following steps of: adding a conversation identifier in data transmitted by the control center, wherein the conversation identifier distinguishes each different conversation process by using different numerical values; different numerical values contain a numerical value which represents that the transmitted data does not contain the signaling related to the conversation; and after the base station receives the data transmitted by the control center, directly sending the data which does not contain the signaling related to the conversation to a terminal. By adopting the realization method of the invention, the base station does not transparently send the data from the control center to the terminal any more and can ensure that the signaling related to the conversation can be sequentially sent to the terminal by identifying the conversation identifier and adopting the method for sequentially caching and processing the caching linked lists so as to save the process of reporting three reports to the control center for each transmitted datum and greatly reduce the uplink signalings sent from the base station to the control center.
