The T314 and T315 timers are used to monitor whether the corresponding CS service and PS service can be restored within the specified time. If the CS service or PS service is not restored during the operation of T314 or T315, that is, the CELL UPDATE CONFIRM is not received before the timeout of T314 or T315 message, the mobile terminal will first release the signaling connection in the CS domain or PS domain and its corresponding wireless resources, but the terrestrial access network cannot perceive the behavior of the mobile terminal, and the terrestrial access network still maintains the relevant wireless resources, making the related Wireless resources cannot be utilized by other mobile terminals, reducing the utilization rate of related wireless resources

The invention relates to the technical field of communications, in particular to a method and device for resource release in a satellite mobile communication system. The method includes that when CS (circuit switch) domain service and PS (packet switch) domain service are started simultaneously and after an earth mobile terminal detects that wireless link with a ground access network fails, and the earth mobile terminal starts a cell update process and starts radio access bearer (RAB) reconstruction timer T314 aiming at the CS domain service and RAB reconstruction timer T315 aiming at the PS domain service; after the reconstruction timer T314 or the reconstruction timer T315 is timeout, and the earth mobile terminal releases signaling connection and radio resources of a CS domain or a PS domain and reports the signaling connection release instructions of the CS domain or the PS domain to the ground access network, so that the ground access network release signaling connection releases the signaling connection and the radio resources of the CS domain and the PS domain indicated by the release instructions, the relevant radio resources can be utilized by other mobile terminals, and utilization of the relevant radio resources can be increased.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for releasing resources in a satellite mobile communication system. Background technique [0002] In the satellite mobile communication system, in the scenario where the earth mobile terminal is in the concurrent circuit switching (Circuit Switch, CS) domain and packet switching (Packet Switch, PS) domain, the wireless link fails due to the deterioration of the wireless environment where the mobile terminal is located. A cell update (CELL UPDATE) process is triggered, and a radio access bearer (Radio Access Bearer, RAB) re-establishment timer T314 in the CS domain and a RAB re-establishment timer T315 in the PS domain are started. The T314 and T315 timers are used to monitor whether the corresponding CS service and PS service can be restored within the specified time. If the CS service or PS service is not restored during the operation of T314 o...
