Detailed ways

Referring to Fig. 1, Fig. 1 is the structure and operation explanatory diagram of the system of a kind of dual frequency mobile phone single frequency access fixed telephone communication network of the present invention. As previously mentioned, it is shown in the figure that in the system of the present invention, the wireless communication network (1) adopts a communication channel of a main frequency (10), such as 900MHz, as long as it is equipped with a 900MHz radio transceiver, its various The main frequency base station (11) is just equipped with the transceiver communication equipment of this main frequency (10), tracks and receives the information of the main frequency (10) of the mobile phone (13), and the main frequency base station (11) will receive the information of the mobile phone (13) Information is sent in the big computer system of mobile phone computer center (12), and sends to the terminal (30) that mobile phone (13) signal will receive through processing, and terminal (30) can be other mobile phones, or other fixed telephones or the like. The wireless communication channel of a secondary frequency (20) is also set on mobile phone (13), and secondary frequency can be the wireless communication channel of 1800MHz for example, and in the present invention, this secondary frequency signal can only be played out from mobile phone, and can not receive this A signal of a wireless communication channel. In the system of the present invention, a sub-frequency base station (3) telecommunications-connected to the fixed telephone communication network (2) is set, and the sub-frequency base station (3) is only used to receive signals sent by the mobile phone (13) with the sub-frequency (20) , and transmit the signal information to the telecommunications terminal (30) to be connected through the connected fixed telephone communication network, such as other mobile phones or other fixed telephones.

Like this, the mobile phone wireless communication network (1) has just saved the resource of a communication channel.
