Abstract
The invention provides a method for realizing flexible adjustment of talk time limit in a cluster system. The cluster system comprises base stations and mobile terminals. The method comprises: a base station sends a timer parameter announcement signal in idle time; with subnet mask parameters, a mobile terminal according with the address in an announcement automatically refreshes and stores talk timer parameters, so that during a talk process of the mobile terminal, the talk timer parameters can be searched according to the address and the talk process are timed with a prompt; once a timer run out the time, the base station sends a signal for clearing a traffic channel to the traffic channel to end the call. The method can overcome the drawback that the prior DMR standards can not set thetimer parameters flexibly according to the class of a call, and integrate address information of the system into a broadcast announcement signal to distribute different timer parameters according to different address packets. In addition, in order to ensure the compatibility of the DMR standards, the method maintains a signal format defined by the standards and can adjust talk time limit conveniently.
