Problems solved by technology
[0009] Therefore, even if there is a slight change in the radiation force, the mobile terminal will log in to a new base station for access, so there is an unnecessary battery consumption problem.
[0010] That is to say, the existing technology is to use the radiation force of the cellular base station to select and reselect the cellular cell for the mobile terminal, so that even if the base station is already in the most suitable cellular cell area, it is easy to generate However, according to the abnormal response of the base station and the abnormal changes in the surrounding area, it is still necessary to frequently choose and reselect among the base stations with the strongest radiation.

Embodiment Construction
[0023] of the present invention figure 2 It is a schematic structural diagram of a mobile communication system, which includes: a base station 61 that handles call setup, release, and handover between the mobile terminal 60 and the mobile terminal; integrates systems such as the base station and HLR to form a call path, and implements the call path for itself. Switching center 62 for operation and maintenance warranty; Visitor Location Register (VLR: Visitor Location Register) 63 that can inquire about visitor location information; Home Location Register (HLR: Home Location Register) 64 that can inquire about the location registration of subscribers and subscriber information .
[0024] The present invention makes a decision on the movement of the cellular cell through the radiation force information of the base station and the location information of the mobile terminal 60 . Each base station holds unique area information that is not duplicated with other base stations.

The present invention discloses a cellular cell switching method of mobile terminal setting change critical value of base station redial force before the switch of the cellular cell by using position information of the mobile terminal and inherence area information non-repeated of the self base station and other cellular cell range, and capable of preventing frequent switch of cellular cell of the mobile terminal reducing the cell consumption of the mobile terminal even the radial force of self base station generates temporary switch, such that achieving easily management of the mobile terminal in the mobile communication system. The invention can restrain the switch of new base station in condition that mobile terminal switches cellular cell because of movement and generates temporary reduction of base station signal, such that a cellular cell selecting method carried out with position information of the mobile terminal for reduction of frequent switch of base station of mobile terminal, saving cell consumption is achieved.
Description
technical field [0001] The present invention relates to a method for selecting a cellular cell (Cell) of a mobile terminal. Specifically, it is a method for selecting a cell of a new base station when the mobile terminal changes the cellular cell due to movement and produces temporary base station signal weakening. Changes are limited to achieve a mobile terminal cellular cell selection method that reduces battery consumption of the mobile terminal. Background technique [0002] Generally speaking, a cellular cell (Cell) is to subdivide a wider area into smaller areas in order to use frequencies more effectively in mobile communications, and set up output base stations in each area to serve as a vehicle phone and portable Telephony provides a medium of communication. A cellular cell (Cell) refers to an area covered by a base station, and the change of a cellular cell refers to the integration of a mobile terminal with a new base station to maintain mobile communication serv...
