Problems solved by technology

[0006] The biggest defect of the existing technology is that the Modem also needs to consume some power when it is in a sleep state, and the power consumption of the Modem is not greatly reduced.

Embodiment Construction

[0051] Among the current technologies for reducing the power consumption of smartphones, many technologies focus on reducing the power consumption of Modem. The main process is that when Modem does not need to work, AP notifies Modem to enter the sleep state through the interface with Modem; when Modem needs When working, notify the AP through the interface with the AP, and the AP wakes up the Modem after receiving the notification. But in many cases, when the received signal of the Modem is very low or there is no signal, the Modem is still working or dormant at this time, and still needs to consume some power.

[0052] The present invention provides a method for controlling the baseband of a communication device. When the received signal of the Modem is very low or there is no signal, the AP controls the Modem to turn off, which can greatly reduce the power consumption of the communication device; further, the AP regularly turns on the Modem to detect the Modem Received sign...

Abstract

The invention relates to the field of wireless communication, and particularly provides a method and a device for controlling the base band of communication equipment, and the communication equipment. The method and the device greatly reduce the power consumption of the base station to further reduce the power consumption of the whole communication equipment. The method comprises the following steps of: transmitting a request of querying a current received signal strength indicate (RSSI) value to the base band; receiving the current RSSI value returned by the base band according to the request; determining the ratio of the current RSSI value to a pre-stored RSSI maximum value of the base band in an application processor; and if the ratio is determined to be less than a first preset threshold, transmitting a shutdown instruction to the base band. The base band can be automatically controlled to be closed if the RSSI value is less than the threshold, so the method and the device greatly reduce the power consumption of a Modem and reduce the power consumption of the communication equipment.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for controlling the baseband of communication equipment. Background technique [0002] With the continuous development of the communication industry, mobile terminals have evolved from the original single call function to voice, data, image, music and multimedia. Mobile terminals can be divided into two types: one is a traditional mobile phone; the other is a smart phone. Compared with traditional mobile phones, smart phones are more and more popular with people because of their powerful functions and convenient operation, and will gradually become a trend in the market. [0003] At present, most of the hardware architectures of smart phones are Modem (baseband)+AP (Application Processor, application processor) architecture. Among them, Modem undertakes the work of communicating with the base station to complete the receiving and sending of sign...
