detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. The method for reducing power consumption of a wireless terminal device provided by the embodiment of the present invention, as shown in FIG. 1 , the method steps include:

5101. Periodically acquire its own transmit power.

5102. Control, according to the transmit power, the opening and closing of the diversity antenna.

The method for reducing power consumption of a wireless terminal device provided by the embodiment of the present invention can periodically acquire its own transmit power, and dynamically control the opening and closing of the diversity antenna according to the transmit power. In this way, on the basis of the original device structure, the diversity antenna can be turned off when the diversity antenna is not needed, thereby reducing the power consumption of the part, thereby solving the contradiction of the small heat dissipation of the device in the prior art, and does not affect User work improves the user experience.

A method for reducing power consumption of a wireless terminal device according to another embodiment of the present invention, as shown in FIG. 2, the method steps include:

5201. Periodically acquire the transmit power of each channel of the self.

5202. Integrate transmit power data of each channel to obtain a transmit power of the wireless terminal device itself.

Since the wireless terminal device needs to obtain the transmission power of different channels, and the transmission power of the different channels may function in different device states, the embodiment of the present invention uses the transmission power of different channels to determine the device state, which can achieve more reasonable dynamic control. .

Further, the integration of the transmission power data of each channel includes obtaining an average value of the plurality of transmission power data, and using the average value as the transmission power of the wireless terminal device itself to perform the determination of step S203 as follows. Here, one of the simplest averaging processes may be to add a plurality of transmit power data and divide by the number of transmit powers.

The integration of multiple transmit powers is because the dynamic control of the diversity antennas causes the baseband to be overburdened too much, and the hardware circuits are frequently charged and discharged, which may increase the power consumption. Therefore, it is necessary to make a time average of the power data of the channels. Processing, this can effectively avoid the ping-pong effect of the diversity antenna.

S203. Determine a relationship between a transmit power of the wireless terminal device itself and a transmit power threshold, and control the opening and closing of the diversity antenna according to the determination result. Wherein, if the transmit power threshold is a point, for example, the transmit power threshold is the first threshold: when the transmit power of the wireless terminal device is less than or equal to the first threshold, the diversity antenna is turned off; when the transmit power of the wireless terminal device is greater than the first threshold The diversity antenna is turned on; or, when the transmission power of the wireless terminal device is less than the first value, the diversity antenna is turned off, and when the transmission power of the wireless terminal device is greater than or equal to the first threshold, the diversity antenna is turned on.

If the transmit power threshold is an interval segment, for example, the transmit power threshold is a segment from the second to the third threshold, wherein the second value is less than the third threshold: when the transmit power of the wireless terminal device is less than or equal to the first 2 At the threshold, turn off the diversity antenna; when the transmit power of the wireless terminal device is greater than or equal to the third value, turn on the diversity antenna. At this time, when the transmit power of the wireless terminal device increases from less than the second threshold to between the second threshold and the third threshold, the switching state of the diversity antenna is kept unchanged, that is, the diversity antenna is turned off; when the wireless terminal device transmits When the power is reduced from greater than the third threshold to between the second and third thresholds, the switching state of the diversity antenna is maintained, that is, the diversity antenna is turned on.

As described above, the transmission power value is in the interval from the second threshold to the third cabinet value, and the ping-pong effect can be avoided. Specifically, as shown in the hysteresis diagram shown in FIG. 3, the abscissa is the transmit power, the ordinate is the receive diversity (RX Diversity), and the "on" and "off" respectively indicate the opening and closing of the diversity antenna. When the transmit power of the wireless terminal device drops to the second threshold or is lower than the second threshold, the state of the receive diversity antenna is changed from on to off, that is, the diversity antenna is turned off; when the transmit power of the wireless terminal device is raised to the third threshold or high At the third threshold, the state of the receive diversity antenna is changed from off to on, that is, the diversity antenna is turned on. Thus, when the signal is good (i.e., when the transmission power of the wireless terminal device drops to the second threshold or lower than the second threshold), the receiving hierarchical antenna has little effect and can be turned off to achieve the effect of reducing power consumption.

In addition, the diversity antenna is only used in the 3G system, and the diversity antenna is not used in the 2G (2nd Generation) system. Therefore, the diversity antenna circuit can be turned off in the 2G system.

Moreover, in the simple upload data service mode, the wireless terminal device does not need to receive data or only receives a small amount of control data. At this time, the diversity antenna is not necessary, and only needs to be received by the main set antenna, so the diversity antenna can also be turned off. . The flowchart of the method for reducing the power consumption of the wireless terminal device provided by the embodiment of the present invention may be as shown in FIG. 4, and includes the following steps:

S401. Determine whether the current bearer is in the 2G system.

5402. If it is carried in the 2G system, the diversity antenna is directly turned off.

5403. If it is not carried in the 2G system, it is judged whether it is only a simple upload data service.

5404. If it is only a simple upload data service, directly close the diversity antenna.

5405. If it is not only a simple upload data service, the diversity antenna switch is controlled according to the transmit power. The specific process can be as described in step S203 of the embodiment.

Of course, in other embodiments, the determination may be first performed according to the service mode (step S403), and then determined according to the bearer system (step S401), and the order of the determination is not limited herein.
