| Today, mobile communication is developed rapidly, no matter which kind of wireless communication cover the areas will all produce the weak signal district and blind area, to some remote areas and blind areas few in number of users, it is too high to erect simulation or the digital base station cost, the infrastructure is relatively complicated too, it is with low costs and erecting simply to offer one for this, but have equipment with effective economy of the small-scale base station function ---It is very necessary to put repeater. Under the drive that the mobile communication cell-phone popularizes rapidly , have repeater got lasting development direct. Repeater can expand the completed simulation and coverage of the digital mobile communication base station directly , it is the most economic and most effective means to solve the blind area , outlying district mobile communication. Repeater appear with development of the mobile communication network, can propagate the base station signal amplified to the above-mentioned areas , give the base station the signal transmission of the mobile subscribers of these areas at the same time, realize moving communication during the platform and base station, solve blind area , weak signal district and outlying district mobile communication and realize " light capacity, heavy to cover " economic effective means most of goal ". Because it is operated simply, installation is convenient, open rapidly and save such characteristics as the expenses ,etc., win the favor from mobile communication facilitator deeply, can respond to the request that users served in conversing to the maximum extent . Just position of the repeater is often in the remote countryside and mountain area, so, it is very inconvenient to safeguard, in order to know in time that the working state of repeater, so the monitoring system of the repeater is developed . It has become an important one in the index of the repeater. This text through to repeater especially network management system of optic fibred detailed description of its function ,on one hand has expounded its realization course, it is even that a very good understanding to the knowledge studied is used in practiced on the other hand. CDMA repeater says on the nation, its technology mainly originates from Korea, but the Korean present use profession is standard and domestic temporary IS-95, the CDMA20001X agreement is not same. Causes Korea to introduce repeater cannot use conforms to the domestic standard network management agreement, creates the association passes regarding the network cover situation cannot promptly grasp, causes the equipment to appear the breakdown cannot promptly process. Moreover Korea exports Chinese all equipment the network management supervisory system control chip and the motherboard all is equipped with the encryption lock, is not easy to explain, several passes through with the Han side coordinates the plan which Han Fang proposes both must consume the massive funds and needs the time cycle is very long, therefore the needle antithetical couplet passes the characteristic which the standard and Korea repeater, the development independent intellectual property rights net tube, has become in this profession the people struggles the discussion question. Domestic until now probably introduced more than 10000 sets from 2001 releases directly for the station, supposition each releases directly for stands all promotes by Korea the transformation, will be allowed to imagine the expense can be how the astonishment. But if voluntarily grinds by us sends network management system will can save one great expenses. Is under this kind of situation, we released directly for in view of Korea stand re-develop develop one set of independent supervisory systems, caused Korea to release directly for stands into conforms to the domestic agreement requirement releases directly for the station, domestically caused it in widely to apply into possibly. Should release directly for the station supervisory system the main function includes to releases directly for the station electric power supply and the radio frequency output and so on carries on the wireless monitoring, realizes releases directly for function and so on breakdown warning as well as control which the station system uninhabited value is punctual. Releases directly for the station supervisory system the basic principle is uses the CDMA network the broad cover scope, with the aid of (short news) serves the function to CDMA network SMS, will release directly for the station active status and the related information transmits by the SMS form through the CDMA network to the monitoring center which will assign or maintains on person's handset, thus will cause the system breakdown to prompt processing; Usually also may through the monitoring center or the handset inquires active status which the assigned location releases directly for stands, guarantees the correspondence network the normal movement. At the same time, because the supervisory system matches has the backup battery, it breaks down when in the alternating current supply still might normally work several hours, thus could reliably pass on the breakdown information the network maintenance. On the one hand wireless MODEM receives from the network management center sends the short news which comes (each kind of inquiry and control information and so on) delivers to the monitoring board, carries on the decodingafter the microprocessor, decomposes the corresponding order and to releases directly for the station carries on the corresponding operation. On the other hand the supervisory system at times gathers each kind of information which releases directly for stands (includes releases directly for station system parameter, monitoring parameter, warning information and so on), and becomes these information encodings the short news promptly transmits through wireless MODEM to the network management center. The paper mainly aims at following several aspects content carries on the research solution: First, studies to Korean and the Chinese is more different than correspondence agreement, because differently belongs to two countries, therefore, has the very big difference in the form, discovers the two the corresponding relations; As well as two between difference, transforms through ours procedure correspondence, solves the software problem which is unable to monitor Next, because Korea releases directly for the supervisory system which stands has the encryption measure, and the majority of components is unable to purchase, therefore we must defer to the supervisory system the principle carry on the electric circuit the design, the original component designation, PCB board work and so on manufacture; Once more, is procedure software and so on application assembly language carries on the compilation to the chip in repeatedly debugs; Finally, is the system test and the paper compilation.
