Embodiment Construction

[0027] Existing mobile terminals supporting the LTE-Advanced network mode will start to enter the idle discontinuous reception state (IDLE-DRX) when the previous data reception is completed and no data is received within a period of time. The power consumption of the mobile terminal largely depends on the proportion of time that the mobile terminal is in the idle discontinuous reception state.

[0028] Currently, there are four options for the period of the idle discontinuous reception state of the mobile terminal supporting the LTE-Advanced network mode, which are 0.32s, 0.64s, 1.28s and 2.56s respectively. This also means that at intervals of up to 2.56s, the mobile terminal will wake up the underlying chip and demodulate the downlink control channel to detect whether there is its own paging information. When the business of the mobile terminal is relatively small or in night mode, frequent wake-up of the underlying chip will bring relatively large power consumption.

Abstract

The invention provides a mobile terminal and a power consumption control method thereof. The method comprises the following steps: judging whether the current working condition of the mobile terminalmeets a preset state switching condition; and when determining that the current working condition of mobile terminal meets the preset state switching condition, controlling the mobile terminal to enter an enhanced non-continuous receiving state. The above scheme can reduce the power consumption of the mobile terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mobile terminal and a power consumption control method thereof. Background technique [0002] Long Term Evolution (LTE) is a long-term evolution of the Universal Mobile Telecommunications System (UMTS) technical standard formulated by The 3rd Generation Partnership Project (3GPP) organization. The LTE system introduces key technologies such as Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input Multiple Output (Multi-Input&Multi-Output, MIMO), which significantly increases spectrum efficiency and data transmission rate, and supports multiple Bandwidth allocation, and supports global mainstream 2G / 3G frequency bands and some new frequency bands, so the spectrum allocation is more flexible, and the system capacity and coverage are also significantly improved. [0003] Long-term evolution-advanced (LTE-Advanced, LTE-A)) is an evolved version of LTE...
