Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] When a mobile terminal enters an area without a network, it cannot camp on a suitable cell (at this time, the mobile terminal loses the network). According to the prior art, the mobile terminal continuously searches the network until it finds a cell where it can camp. However, from the perspective of power saving, continuous network searching in the absence of a network is not only power-consuming but also unnecessary. network, and in order to further save power, the time interval of searching the network (searching the network cycle) T 周期 Adjustments are also made dynamically.

[0025] Please refer to figure 1 , the average standby current I of the mobile terminal intermittently searching the Internet under the condition of no network 待机...

Abstract

A method for searching network by mobile terminal includes setting network searching cycle and network searching frequency of using said network searching cycle, carrying out network searching according to set network searching cycle and relevant network searching frequency after network is lost from mobile terminal.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a network searching method for a mobile terminal. Background technique [0002] Power-saving technology is a key technology in mobile terminal design, and the standby time of a mobile terminal is a key indicator to measure its performance. The research on power-saving technology for mobile terminals has been started very early and has achieved phased results. However, these power-saving technologies are all implemented when there is network signal coverage. After the mobile terminal leaves the network coverage area, it will search the network continuously, and the network search method used is full-band search network, which will cause the battery of the terminal to be exhausted soon, and make the standby time of the mobile terminal in the case of no network Far less than the normal standby time when there is a network. Especially for the Time Divisi...
