The Management System Of Repeaters

Today, mobile communication is developed rapidly, because with a varied topography, will appear in weak signal district, blind area and dead angle of the cover area of wireless communication unavoidably, and Repeater because it is operated simply, installation is convenient, offer service rapidly and become the most economic means to solve this difficult problem in characteristics, such as expenses, etc. Repeater belong to enlarging equipment I, it reach a kind of radio that the signal strengthen transmit and change trains the equipment to get up while wireless communication is transmitted frequently to stand to put directly. Basic function stood to put one radio frequency signal power-strengthening device directly. Its work offers a transparent radio frequency pass way for BTS and MS between BTS and MS. Put and stand in the down chain directly, pick up the signal from the existing cover area of alms giver's aerial, through band-pass filter being to bring coherent signal of outside carry on kind segregation extremely, the signal that will strain the wave transmits to and waits to cover the area again after putting and amplifying in work. In up going in the chained route, cover movement set of area signal of cell-phone is it amplify chain treated to is it stand to corresponding base to transmit to up go by way of same job, thus reach the base and stand and transmit with the signal of the cell-phone. Have, is it may finish to work meanwhile to transmit to charge to fall. For be able to from on, fall there aren't two piece the directions, is it join with one alms giver aerial to need to stand to put directly, in order to communication stands with base, at the same time, still need to link with business aerial, in order to cover and move the blind area. Releases directly for the station is to the correspondence blind spot effective supplement, generally installs the condition is quite bad, moreover installs the quantity are quite many, the installment scope is more dispersible, like this if must carry on regular scene maintenance to it, perhaps needs the quite many manpower, the physical resource. Moreover repeater the general work is stabler, like this to the manpower, the physical resource resources is one kind of waste. Uses releases directly for the station may expand the system basic station cover scope, greatly saves Specially in high level building, underground (for example subway), blind spot and so on under special environment, will release directly for stands fully displays its superiority. If releases directly for the station has the long-distance monitoring the ability, sits may to govern the area in the network management center releases directly for the station working condition knows from a to z, how can it be that isn't both can know the equipment the movement situation, and can save the very many resources. Like this, released directly for the network management system which stood is born. This system take reports to the police on own initiative with the long-distance inquiry, the long-distance establishment function as the focus, causes the network management center the operator can with ease realize the condition which the long-distance monitoring repeater. Whether is the repeater is it stands fine or not index have mainly to put directly to weigh. Low IP3, low in noise coefficient, complete machine dependability, good technological service and intelligent degree (such as network management, long-range to control), etc., and particularly an important one is that the network management system of the station is put directly among them. The main function of the network management system has: Inquire about long range; Long range control; Report an emergency and ask for help or increased vigilance to show etc. This thesis , through to systematic description, such as brief introduction of description, function with systematic network management, the design and implementation method standing, etc. are set free directing, on one hand has described that shows the realization course of the network management system of the station directly; Have even strengthened the digestion of the knowledge of the database studied to understand further on the other hand. The tradition releases directly for the station maintenance difficulty, the cost is high, moreover cannot as necessary monitor, cannot as necessary report the active status which releases directly for stands, the wireless supervisory system is one uninhabited automated supervisory system, may conveniently manage releases directly for the station system, realizes each kind of monitoring function. Releases directly for the station network management system series monitors through the short note news for the carrier releases directly for the station system. Uses the short news realizes this system has the cost is low, the use scope is broad, is reliable and so on the merit. This releases directly for the station network management supervisory system uses releases directly for the station side and the server side all uses wireless MODEM the way, completely independently grinds sends releases directly for the station network management system, the realization long-distance monitoring. The correspondence agreement uses " center the League of Nations straight from end to end puts station network management technology standard ", the monitoring content and each monitoring request all conforms to the agreement requirement, and with uses this agreement all long-distance supervisory systems is compatible.The network management system mainly and releases directly for the station two parts by the network management center is composed, two between uses the short news for the carrier transmission monitoring data: Central control software will control the order data codes the short news content, will transmit to the observation and control board, the short news which on observation and control board microprocessor docking will receive carries on the decoding, will decompose the corresponding order and carries on the corresponding operation; After then will process the information encoding becomes the short news transmits to the central control center; After central control software receives the information, decoding and will moniter information demonstration on screen. The network management center centralism management repeater and controls the correspondence service which the data flows to. Moves between the communications network and the NMS server realizes the correspondence and the agreement transformation. User warning sum accumulator which stores up the NMS server according to, divides all day long, unit and so on Zhou, Yue, year, enables it to be allowed to print or by the document form use, but also may nimbly produce the report form, the statistical data and so on. Repeater partially locates the uninhabited control the area, it is carries on the correspondence through the short information way and control center server MODEM, namely to releases directly for the station monitoring is the CDMA net and the short information center which provides using the BTS equipment completes. The network management server in order to monitor releases directly for the station is responsible the SMS short information the code and the decoding, and is responsible for the database, other equipment which manages the monitoring needs (terminal server, printer and so on); The network management server by the SMS way, monitors each releases directly for the station, and the gain information, using the screen and the printer reports gives the operator; Has the urgent warning confirms the function; All data by database form management. The network management system mainly has below the function System Manages :Mainly carries on the system parameter the disposition, with connection way and database management. User Management: : Includes the account number management, the secret cipher change, cancels with the function which registers again. Repeater Management: : The region information which includes which the increase, the deletion, the change releases directly for stands the long-distance connection parameter and repeater. May demonstrate all releases directly forinformation and so on position, name, type, this machine number, warning condition which stands. Operation Maintenance:: To releases directly for the station carries on the long-distance inquiry and the control. Warning Manages: Real-time gathering releases directly for the warning information which stands, has the warning confirms the function. Processing which the inquiry releases directly for which stands the historical warning information and the breakdown removes, has the formidable warning informs the function. Diary Management: May examine the system, releases directly for the station operation and the warning all historical information. Statistical report form:: To releases directly for the parameter information which stands, the warning record and the system diary carries on the statistics and by the report form output. This text solves four problems mainly: First, brief introduction of systematic function of network management; Second, the network management system realizes the course; Third, Study of the knowledge of the database; Forth, the procedure realizes.
