Abstract

The invention provides a device for detecting abnormal detachment of mobile terminals with session right and method thereof, which is applied to a cluster system comprising PDS, a plurality of BSC and a plurality of mobile terminals, wherein, the method includes: step one, after a session right request of the mobile terminal in the cluster system is received, PDS sends terminal session right authorization messages to partial or whole BSC of the cluster system; step two, after mobile terminal session right authorization messages are received, partial or whole BSC returns status notification messages to PDS, if abnormal detachment occurs, does not return status notification messages; step three, if any status notification message is received in a certain collecting cycle, PDS releases session right of mobile terminals with session right, if at least one status notification message is received, maintains status of mobile terminals with session right, realizes hard handoff between BSC, also can track status of mobile terminals with session right.

Description

technical field [0001] The invention relates to the field of trunking communication, in particular to a device and method for detecting abnormal off-network of a mobile terminal having the right to speak. Background technique [0002] Based on the CDMA 2000 professional trunking GOTA system, the PTT (Push To Talk) group call service is also called "Push To Talk" service, which refers to the "point-to-point" and "point-to-point" services that use half-duplex communication to achieve real-time direct connection. Multipoint" voice communication. The calling party only needs to press a key, without dialing and waiting for the other party to pick up the phone, the call can be connected immediately, initiate a call to one person or a group of people, and quickly establish a talking group, and only one person can speak at the same time. [0003] The trunking dispatching server (PTT Dispatching Server, PDS) is responsible for realizing functions such as controlling trunking calls, ...
