Problems solved by technology

[0006] However, in the prior art described above, the mobile communication terminal decides to reselect a cell by referring to the received signal level and the parameters of the system information without considering the battery power. Re-selection consumes a large amount of current, shortening the standby time

Embodiment Construction

[0013] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0014] figure 1 is an exemplary diagram of a mobile communication system to which the present invention is applied.

[0015] The base station governs the cell, and the cell partially or completely overlaps. The cells are composed of large macro cells 11 , 12 and small pico cells 13 , 14 , 15 located within the macro cells 11 , 12 . Multiple cells are gathered together to form a routing area, and the routing areas are gathered together to form a location area. The area or routing area is operated by different communication operators.

[0016] figure 2 It is a diagram showing an example of a wireless environment of a mobile communication terminal for explaining the present invention.

[0017] The mobile communication terminal 20 calculates the path loss standard variable (C1) and the reselection standard variable (C2), and decides whether to reselect...

Abstract

The invention relates to a section select condition change method of mobile communication terminal, which present mobile communication terminal will consume lot of current to re-select the section even when the battery energy is lower, to shorten the waiting time. The invention is characterized in following steps: judging, that judging the maximum battery level and the battery energy when re-selecting the section; calculating, that according to the battery energy, adding battery compensate value to the C2 value of server section, and calculating the re-select standard variable; section re-selecting, that according to the re-select standard variable, judging the re-select standard condition of section to decide the section re-select. The invention can change the section re-select condition on nearby section to reduce the re-select and the electric consumption, and improve the waiting time when the battery energy is lower.

Description

technical field [0001] The invention relates to a method for changing cell selection conditions of a mobile communication terminal, in particular to a method for changing cell selection conditions of a mobile communication terminal which can reduce cell reselection and prolong standby time when the battery power is low. Background technique [0002] The mobile communication network divides the area to form a cell, and two or more cells that are different from each other overlap to form a border area or service area to form a communication network. The base station manages more than one cell, and the mobile communication terminal is located in the service cell and uses communication services. [0003] When the user moves with the terminal, the mobile communication terminal detects the received signal level of the serving cell and the adjacent cell, decides to select another cell, selects an effective cell, and provides a stable call environment. [0004] In the existing mobi...
