Embodiment one
The embodiment of the present invention one provides a kind of Poewr control method, take Fig. 1 as the application scenarios schematic diagram of the embodiment of the present invention, the method is used for controlling the power of MiFi equipment, MiFi equipment is connected to terminal equipment (i.e. MiFi equipment with between terminal equipment for WIFI is connected) by WIFI function, and MiFi equipment is connected to LTE network by LTE function.Wherein, generally closer (as in the scope of a meeting room), the distance of MiFi equipment and LTE network is not fixed in the position of MiFi equipment and terminal equipment.
Under LTE feeble field environment, because LTE side is the entrance that user accesses the Internet, therefore the downloading rate of MiFi equipment depends on the downloading rate of LTE side, in addition, because the WIFI function of MiFi equipment does not have power control mechanism, the WIFI transmission power of MiFi equipment is determined by preset value when dispatching from the factory, therefore no matter LTE high field or LTE feeble field, the WIFI side of MiFi equipment all adopts identical transmitting power, and adopt identical transmitting power to be the main cause causing interference larger, therefore need in the embodiment of the present invention to reduce WIFI transmission power according to certain algorithm, ensure that the downloading rate of MiFi equipment can be close without the downloading rate under WIFI interference, downloading rate under disturbing without WIFI is USB(Universal Serial Bus, with universal serial bus) direct-connected speed, and the direct-connected speed of USB refers in the WIFI module of closing MiFi equipment, MiFi equipment to be connected with main frame the LTE module speed recorded by USB.
Further, WIFI is a time-division system, and when being operated in same frequency, descending and up signal path loss is equal, and therefore transmitting apparatus can estimate the signal magnitude that receiving equipment receives according to the signal magnitude received.On this basis, suppose that MiFi equipment is identical with the transmitting power of terminal equipment to MiFi equipment to the transmitting power of terminal equipment, namely TX-A(MiFi equipment is to the transmitting power of terminal equipment)=TX-B(terminal equipment is to the transmitting power of MiFi equipment), then MiFi equipment Inspection to received signal strength corresponding to terminal equipment (performance number when namely the transmitting power of terminal equipment the arrives MiFi equipment) received signal strength (performance number of the transmitting power incoming terminal equipment of MiFi equipment) corresponding with the MiFi equipment that terminal equipment detects identical, namely the received signal strength size that RX-A(MiFi equipment is corresponding) received signal strength size that=RX-B(terminal equipment is corresponding).
Based on above-mentioned analysis, as shown in Figure 2, this Poewr control method can comprise the following steps:
