Code division multiple access global system for mobile communication (CDMA GSM) terminal and method for reducing power dissipation

Abstract

The invention discloses a code division multiple access global system for mobile communication (CDMA GSM) terminal and a method for reducing power dissipation. The CDMA GSM terminal comprises an application module, a 3G wireless communication module and a 2G wireless communication module, wherein the 3G wireless communication module is used for executing videophone services in a grouping (PS) service and a circuit (CS) service, the 2G wireless communication module is used for executing CS services expect the videophone service; and when the CDMA GSM terminal is powered on, the application module firstly controls the 2G wireless communication module and the 3G wireless communication module to begin operating and then controls the 3G wireless communication module to enter the sleep state. The invention proposes an innovative power management strategy, thus the terminal power dissipation can be reduced maximally and the cruising power of the terminal can be improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a dual-network dual-standby terminal and a method for reducing power consumption. Background technique [0002] With the gradual development of domestic 3G network construction, the three major mobile communication operators have officially entered the 3G era. However, due to the initial stage of the construction of the current 3G network and the next period of development, the coverage level of the 3G network has been continuously optimized and improved for more than ten years compared with the 2G network. All natural villages) or the depth of coverage (such as indoors, basements and subways, etc.), there is a big gap, so major operators also coincidentally regard the long-term coexistence of 2G and 3G dual networks as their own operating goals and strategies. China Mobile even put forward the three-no principle of "no change of card, no change of number, and no registration...

Problems solved by technology

[0004] In order to solve the above problems, a dual-network dual-standby terminal with a dual-modem architecture scheme of 2G and 3G dual-network dual-standby and PS and CS business offloading is proposed, but the terminal of the dual-modem architecture scheme still has serious power consumption and poor battery life. question
