Description

Mobile communication base station centralized monitoring system and this system monitoring method

This invention mobile communication base station centralized monitoring system and this system monitoring method belong to moving communicating field, it is applicable to the monitoring and the control of 900MHZ cellular mobile communication base station, can accurately and timely fix a breakdown, for the normal operation of mobile radio communication provides guarantee.

In prior art, the scheme that is used for base station monitoring for the simulation mobile radio communication has following two kinds of schemes in existing use.First kind is by switch the base station to be monitored, because the switch personnel are unfamiliar with the base station, lack perceptual knowledge, the unavoidable appearance judges by accident on judging, shortcoming is: subjectivity and uncertainty make the base station personnel in failure judgement, carry on instrument and the various base station equipment and make a fault, time-consuming bothersome, and the instruction system of switch and base station is different, and the function of the many test channel in base station can't be finished on switch.Second kind is to enter base station system by the base station engineer by dial mode by dialing MODEM (modulator-demodulator), but must there be direct-dial telephone each base station, and transmission rate is low, the error rate is higher relatively, and mobile network is in order to reach bigger communication coverage, a large amount of base stations is installed in the architectural of non-telecommunication department, therefore for having a telephone installed and dial MODEM difficulty more.Up to now, this supervisory control system still is difficult to realize.And for GSM (digital network) mobile radio communication base station monitoring is mainly realized by operation maintenance center (OMC) and base station controller (BSC).But because the operating personnel of OMC and BSC are unfamiliar with the base station, lack perceptual knowledge, the unavoidable appearance judges by accident on judging, shortcoming also is: subjectivity and uncertainty, make the base station personnel in failure judgement, carry on instrument and the various base station equipment and make a fault, time-consuming bothersome, do not find the better method head it off up to now.

The purpose of this invention designs in order to overcome above-mentioned shortcoming, is that a kind of agreement and speed are changed and the method by direct-connected mode centralized monitor mutually.The potentiality of existing equipment are fully excavated in this invention, the rapidity of transfer of data and the characteristics that the error rate is low and transmission rate can be revised have as required at any time been brought into play, and has good graphical interfaces for analog mobile communication system centralized monitor main frame, enrich and practical database, practical operation is had directive function.This invention also provides good centralized monitoring method for GSM (digital network) mobile radio communication.The present invention is real-time to the monitoring of base station, and the reliable results of failure judgement is that a kind of mobile communication station centralized monitoring system with very high practical value reaches method for supervising quickly and accurately.

The design philosophy of this invention mobile communication base station centralized monitoring system and this system monitoring method is that principle, software instruction, multi-user's deck and computer and the database that application protocol and speed are changed mutually realized,

Describe design of the present invention and technical characterictic thereof below in conjunction with accompanying drawing in detail by the two large divisions:

Be that accompanying drawing 4 GSM (digital network) mobile communication base station centralized monitoring method figure is illustrated below.By Xi 4-1 the agreement that transmits of the 4-9 TTY interface of the true base station controller of 4-3 (BSC) of base station controller part be V.24 signal, by the 48RS-232 interface cable, enter 4-4 rate protocols transducer (ITA-703), except that transmission rate is changed into 9600kbps, table 2 is pressed in other all wire jumper settings, two tone frequency channel wires of drawing from the emission port of 4-10 rate protocols transducer are connected to base station controller 4-5 relay transmission equipment (PCM) partly, two tone frequency channel wires of drawing from the receiving port of 4-11 rate protocols transducer are connected to base station controller PCM partly, speech plate on the PCM must change database into, and the ground wire on the database need be connected with the 4-12 ground wire on the rate protocols transducer.Signal arrives the PCM at Xi 4-2 centralized monitor center through the 4-14 relay transmission line (speed is 2Mbps) of the PCM of base station controller part, two tone frequency channel wires that the receiving port of the rate protocols transducer at centralized monitor center is drawn are connected to the PCM at centralized monitor center, two tone frequency channel wires that the emission port of the rate protocols transducer at centralized monitor center is drawn are connected to the PCM at centralized monitor center, signal enters 4-6 multi-user's deck, each RS-232 interface of multi-user's deck can be supported the transmission rate of asynchronous 300-38400bps, can increase according to the actual needs and can subtract.Link to each other with the RS-232 interface cable, output on the 4-7 centralized monitor main frame.

Advantage of the present invention and good effect are:

Entered since the eighties, domestic and international all kinds of mobile communication business development are very rapid, wherein outstanding with cellular mobile telephone.Wherein Development in China is very noticeable again.To the end of the year one nine nine five, the mobile phone user of China has reached 3,600,000 families, occupies the 4th in the world, and its popularity rate only is 0.3%.Compare with developed country in the world, to having the country of 1,200,000,000 populations, this ratio is still very little.If popularity rate reaches 1%, the mobile phone user will be in necessarily, is to be difficult to the big figure calculated more to the world.

In order better to be user's service, just more comprehensive and strict to the requirement of maintenance levels.Because cellular mobile telephone, its base station distribution is very wide, has brought very big difficulty to maintenance work.Traditional maintaining method (being that switch is found alarm notification base station maintenance center, the fault of sending someone again to handle) can not satisfy user's needs.Centralized monitor in the past (promptly adopting the method for dialing MODOM) is suffered from telephone wire can't satisfy the demand (a lot of base stations are build non-telecommunication department in architectural) again, leased telephone line needs great amount of investment again simultaneously, with Beijing is that annual just need of telephone wire of example spends 15000 yuans, full Beijing only this item just needs last 1,000,000 yuan, and the national fund that is spent is especially in necessarily.This does not also comprise the base station because fault can not be carried out telephone charges that normal talking lost and the negative effect in the society.This shows that centralized monitor is imperative.Mobile communication base station centralized monitoring system of the present invention and method thereof, make the existing 900MHZ cellular mobile communication base station that is dispersed in the different location, can be by direct-connected mode centralized monitor, there are good graphical interfaces and abundant and practical database in this system for the simulation mobile radio communication, provide good foundation to accurate analysis and the various faults of timely processing, the present invention not only provides processing speed and the accuracy that ensures but also improved significantly existing base station fault for the normal operation of mobile radio communication, saved the communication resource and maintenance cost greatly, this method for supervising also is suitable for GSM (digital network) mobile radio communication.
