Embodiment 2

[0079] The difference between the second embodiment and the first embodiment is that, on the basis of the first embodiment, an operation of increasing or recovering cell measurement is further added.

[0080] figure 2 A method of controlling a mobile terminal by detecting a sensor is shown. The method includes detecting an output signal of a sensor in the mobile terminal, and judging whether the mobile terminal is in a moving state or a stationary state (201); when the mobile terminal is judged to be in a stationary state, reducing or stopping other PLMN / Measurement of mode cells (203); increase or resume measurement of other PLMN / mode cells (205).

[0081] In the second embodiment, reducing or stopping the measurement of other PLMN / mode cells is not conducive to the terminal camping on the PLMN with the best signal quality. Therefore, the first time threshold and the second time threshold may be set, for example, set to 10 minutes and 1 minute respectively. Whenever the ...

Embodiment 3

[0084] The difference between Embodiment 3 and Embodiments 1 and 2 lies in the control of the reduction measurement degree.

[0085] The reduction degree of cell measurement can be variable or fixed, or a combination of both.

[0086] A fixed approach, as opposed to dividing the frequency of measurements into normal and reduced. For example, the measurement period of the current network configuration is 1.28 seconds, and when the measurement is reduced, the measurement period is 2.56 seconds. Then, once the mobile terminal is in a static state, it reduces the measurement of the cell; otherwise, it measures according to the normal measurement frequency.

[0087] There are many ways to change the method that can be used.

[0088] For example, a plurality of levels with different degrees of measurement reduction may be set, and the longer the duration of the mobile terminal being in a stationary state, the higher the degree of measurement reduction. If the static lasts for mor...

Abstract

The invention provides a method of controlling a mobile terminal by detecting a sensor. The method comprises the steps of detecting an output signal of the sensor in the mobile terminal, judging the moving state of the mobile terminal, and adjusting the mobile terminal according to the moving state of the mobile terminal to do at least one operation: measuring cells, selecting a lingering public land mobile network or selecting a mode.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for controlling a mobile terminal. Background technique [0002] UMTS (Universal Mobile Telecommunication System, Universal Mobile Telecommunications System) is a third-generation (3G) wireless communication network technical standard defined by 3GPP (Third Generation Partnership Project, Third Generation Partnership Project). The UMTS network consists of a core network and an access network. The core network includes a CS (Circuit Switching, circuit switching) domain and a PS (Packet Switching, packet switching) domain. The CS domain provides services based on circuit switching, such as voice services; the PS domain provides services based on packet switching, such as Internet access. 3GPP maintains or formulates 2G (second generation) standards such as GSM, GPRS, and EDGE, as well as 3G standards such as WCDMA and TD-SCDMA. Another system of 3G technolog...
