Method for selecting serving cell and mobile terminal

Abstract

The embodiment of the invention discloses a selection method of service cells and a mobile terminal. The method comprises the following steps: obtaining a location area code of the service cell currently resided by the mobile terminal and marking as a first location area code; detecting whether the mobile terminal is in a searched service cell or not; if yes, inquiring whether the location area code of the service cell is the first location area code in the searched service cells or not; if yes, increasing bias for the service cell corresponding to the first location area code. The mobile terminal comprises a location area code marking unit used for obtaining the first location area code of the currently resided service cell, a detection unit used for detecting whether the mobile terminal is in the searched service cell or not, a search unit used for querying whether the service cell of the first location area code exists or not, and an adjustment unit used for increasing the bias for the service cell corresponding to the first location area code. The selection method of the service cells and the mobile terminal disclosed by the invention can reduce the probability that the mobile terminal updates positions for signal fluctuations, and further decreases interference on the other card of a dual-card double-standby single-pass mobile phone because one card updates the positions.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for selecting a serving cell and a mobile terminal. Background technique [0002] As a basic tool for communication, mobile terminals have been widely used, but mobile terminals will temporarily lose service, such as entering elevators or basements and other places with poor communication signals; During the call, Card 2 will temporarily lose service. When card 1 ends the call, card 2 will search the network again. [0003] Sometimes due to small dynamic changes in the mobile phone signal, boundary effects, etc., the mobile terminal has a probability to select another cell with a different location area code LAC (location area code), causing the mobile phone to update the LocationUpdate; this will not only waste the mobile phone and The resources of the network will also interfere or interrupt some steps of the card 1, such as FAST RETURN and so on.

[0003] Sometimes due to small dynamic changes in the mobile phone signal, boundary effects, etc., the mobile terminal has a probability to select another cell with a different location area code LAC (location area code), causing the mobile phone to update the LocationUpdate; this will not only waste the mobile phone and The resources of the network will also interfere or interrupt some steps of card 1, such as fast fallback FAST RETURN, etc.
