CDMA, WCDMA, TD-SCDMA, FDD-LTE, TD-LTE), operator is more, and base station cell is more and mobile phone standard model waits spies more
Point；It needs largely to detect base station if the whole network control (detecting) to be reached, since it is desired that by frequency range button-type, pressing operator
It is respectively arranged, otherwise violation mobile phone is obtained with communication and (manages the user outside area to neighbouring signal and can also generate in detecting base station
Interference), certain mobile phones are also equipped with the function of detection-proof base station, therefore the construction cost for detecting base station system is very high；2, another
A difficult point is, binding signal access control is also needed under the premise of realizing detecting, common signal access control system is again
Divide various technologies: common are Sweeping nonlinearity type, white noise interference type, also just like certainly dry in the storage forwarding patent of our company
Type etc. is disturbed, how these signals access control mode coexists with detecting and the good of private network, should realize the signal of violation mobile phone
Access control and detecting, realize the communication of legitimate user again, also do not have pertinent literature to refer at present.3, under normal conditions, with
Our company's storage forwarding patent is the signal access control patent of representative, effective just for single device, for needing to implement region
The case where control, needs to use more equipment, and how these equipment can efficiently realize signal access control, at present also not
There is pertinent literature to refer to.

It stands and establishes uplink downlink connection by merging access unit AU, the far-end unit RU in wireless signal access control module also makees
To detect the forward relay with private network.
The utility model in addition between antenna and main control signal cell S U and far-end unit RU use coaxial cable connect,
Other as main control signal cell S U with merge access unit AU, fusion access unit AU and far-end unit RU between be all made of number
Word optical fiber connection, it can be achieved that larger range of efficient covering by way of digital optical fiber remote.The utility model collection signal pipe
Control, detecting, private network function introduce the working principle of modules below with reference to this system in one respectively:
1, wireless signal accesses control module working principle: the air base station signal come in by receiving antenna port is through coaxial
Cable enters each frequency band filter of main control signal cell S U, amplifies after filtering output through low-noise amplifier, it is laggard
Make at software wireless electric treatment, filtering and storage forwarding algorithm into FPGA again after ADC digital after low-converter frequency conversion output
Reason etc., obtains the base belt controling signal of corresponding band signal of communication, which passes through digital fiber as main control signal
It is transmitted to fusion access unit AU.Merge access unit AU, by main control signal cell S U transmission come main control signal and
The detection signal and private network signal that detecting module, the transmission of private network module come are via digital optical fiber transmission to far-end unit RU.Distally

2, detect communication work principle: detecting module includes at least one detecting base station, and the detecting base station is for detecting
The IMSI of mobile phone, according to preset white list, if the IMSI not on white list, is just judged as blacklist, i.e. violation hand
Machine, and the behavior of violation mobile phone is done resident；Jump to mobile phone on private network base station white list mobile phone signaling.It is described at least
One detecting base station is accessed control module uplink downlink with wireless signal by fusion access unit AU and is connect, and wireless signal connects
Enter forward relay of the far-end unit RU also as detecting in control module.Implement detecting function when, downlink are as follows: one or
The fused access unit AU of signal that multiple detecting base stations issue carries out the digitlization of software radio, is reached by digital fiber
Remote unit RU, remote unit RU revert to radio-frequency carrier signal (namely detection signal part in integrated control signal) and pass through
Transmitting antenna sends arrival access control area to be used to get in touch with the mobile phone in access control area, and wireless signal access here is controlled
Molding block has managed the signal of all public networks when working, do not implement control to detecting base station and private network.Uplink is on the contrary, disobey
It advises mobile phone and base station is detected by access.
