Problems solved by technology

[0005] However, there are defects in the existing technology: in the multi-mode mobile phone of the prior art, each wireless communication system corresponds to an antenna system. Due to the mutual coupling of the antennas between different wireless communication systems, the flow of the ground current caused by the flow of the ground current leads to serious signal interference.
And since every additional wireless communication system must increase a corresponding antenna system, the increase in the number of antennas not only increases the volume of the equipment, but also increases the cost of the equipment

[0068] The first embodiment: as Figure 6 As shown, U1 is the CPU of the Bluetooth communication system, U2 is the CPU of the WLAN, and U3 is a radio frequency switch. When U2 outputs high level, the polling signal commanding WLAN work is high, logic device 1 outputs high level, Bluetooth outputs low level, logic device 2 outputs high level, vc1=1, vc2=0, the RF switch will The antenna is connected to the WLAN, and the WLAN listens to the surrounding wireless signals. When information exchange is required, the WLAN outputs a working signal to the communication system 2. When the communication system 2 does not work, the logic device 2 outputs a high level, and Bluetooth outputs a low level. Logic device 2 Output high level, vc1=1, vc2=0, U3 still connects the antenna system to WLAN, after WLAN completes information exchange, polling signal output is low, WLAN working state output is low, logic device 2 outputs high level, vc1= 0, vc2=1, U3 connects the antenna system to the B...

[0071] Second embodiment: Figure 7 It is the implementation circuit of this embodiment. The central processing unit provides control instructions for the first wireless communication system and the second communication system, the central processing unit provides A1, A2 control instructions, and the central processing unit controls the operation of the communication system in time division, time period 1, A1=1, A2=0 , the antenna system is connected to the first communication system, and the first communication system listens to information. If information interaction is required, the first communication system outputs a B1=1 signal, and the central processing unit maintains A1=1, A2=0; the first When the communication system does not need to perform data interaction, the first communication system outputs B1=0, the central application processing unit sets A1=0, A2=1, the antenna system is connected to the second communication system, the first communication system intercepts...

[0073] Embodiment 3: The solution of the present invention will be described below by taking devices of communication systems with different communication frequency bands as examples. In this embodiment, the central processing unit is a CPU, the communication systems are WLAN, Bluetooth, and GSM / GPRS, and the three communication systems multiplex a common antenna system through an antenna switching unit. The instructions issued by the CPU control the working status of the communication system, that is, define the rules for how the three communication systems work in time-sharing, so as to ensure that WLAN, Bluetooth, and GSM / GPRS occupy the medium in time-division. The method of using this device for communication is: when the CPU issues an instruction to require the WLAN to occupy the channel, the CPU starts the work of the WLAN at the moment, and notifies Bluetooth and CDMA to prohibit work; at the same time, the polling signal sent by the CPU controls the radio frequency swi...
