TAL update method and equipment under mobile communication network and based on mechanic operating type

The invention discloses a Tracking Area List (TAL) update method and equipment under a mobile communication network and based on a mechanic operating type. The method includes the steps that a network side device receives signal strength information reported by an UE, wherein the signal strength information includes received signal strength of a current serving cell and received signal strength of neighbor cells; a tracking area (TA) corresponding to the serving cell is added to the TAL by the network side device and the corresponding TA of the neighbor cells with the received signal strength bigger than the difference value between reselection threshold value of the cells and comparison threshold value is added to the TAL; the TAL is sent to the UE by the network side device and stored by the UE. In the embodiment, since it can be avoided that the UE moves beyond the range of the TAL and then triggers location update request, the frequency of initiatively starting location update request of the UE can be reduced. Cost of random access and control signaling brought by sending the location update request can be reduced, and then resource occupation of random access and control signaling is reduced.
