Description
Technical field
The present invention relates to mobile communication technology, particularly have the mobile communication technology of high reliability data transmission performance.
Background technology
Since the eighties, analog mobile communication system was born, mobile communication obtained develop rapidly in the whole world in short twenties years, and along with first to the releasing one after another of 3-G (Generation Three mobile communication system), mobile communication increases day by day to the influence of human lives and work.
The maximum difference that mobile communication is communicated by letter with landline telephone is that the user is in mobile status, this just means that also the coverage rate of mobile communications network must satisfy user's mobility, therefore, with GSM is example, the covering of GSM network is expanded to small and medium-sized cities from the big city, expand to the suburb from down town commerce, the intensive area of user, when solving network whole nation covering problem, also just realized the national automatic roaming of GSM.
Gsm system is made of three main subsystems that are coupled to each other, and connects by certain network interface and user.Three subsystems are base station sub-system (Base Station Subsystem, be called for short " BSS "), network and switching subsystem (Network and Switching Subsystem, be called for short " NSS ") and operation support subsystem (Operation Supporting Subsystem is called for short " OSS ").Travelling carriage (MobileStation is called for short " MS ") is the equipment of user's practicality in the GSM mobile radio communication, and the type of travelling carriage mainly contains Vehicle mounted station and hand-held station (mobile phone).
In gsm system, BSS is responsible for providing and manage transmission channel between NSS and MS, particularly comprises the wave point management between the functional entity of MS and gsm system.NSS is responsible for the management of communication service, guarantee MS and relevant public network or with other MS between set up and communicate by letter.That is to say the direct and MS intercommunication of NSS, the also direct and public correspondence net interconnecting of BSS.MS, BSS and NSS form the entity part of gsm system.OSS then provides these actual motions control, maintenance and management partly for operator.
Wherein, BSS is made up of base transceiver station (Base Transceiver Station is called for short " BTS ") and base station controller (Base Station Controller is called for short " BSC ") two parts functional entity.BTS is responsible for wireless transmission, BSC is responsible for control and management.
BTS is a base transceiver station, also is the important component part of BSS.It is controlled by BSC, finishes the conversion between BSC and the wireless channel, realizes the wireless transmission of air interface between BTS and the MS and relevant controlled function.BTS mainly partly is made up of Base Band Unit, carrier frequency unit, control unit and air feedback unit etc.Base Band Unit is mainly used in necessary speech and data rate is adaptive and chnnel coding etc.; The carrier frequency unit is mainly used in the transmission of modulating/demodulating and radiofrequency signal and reception etc.; Control unit then is used for the operation and maintenance of BTS.Air feedback unit is mainly used in the shunt of radiofrequency signal/close the road and radiofrequency signal is become electromagnetic wave or electromagnetic wave is converted to radiofrequency signal.
BSC is the control section of BSS, finishes the management to various interface, bears the management of Radio Resource and radio transmission parameter.BSC mainly consists of the following components: the management of relevant interface, control and processing section; The common process part; Switching part.
BSS is made up of a BSC and one or more BTS, and a BSC can control dozens of BTS according to the telephone traffic needs.BTS can directly link to each other with BSC, also can pass through Base Station Interface Equipment (Base Interface Equipment is called for short " BIE ") and adopt the connected mode of far-end control to link to each other with BSC.
The GSM server is (the Mobile Switching Center of mobile switching centre, be called for short " MSC "), it controls the business of the BSC in all compasss of competency, provide function of exchange and with system in being connected of other function, and interface function with fixed network is provided, its mobile subscriber and mobile subscriber, mobile subscriber and fixed network user are connected to each other.MSC is from intrasystem three databases, be attaching position register (Home Location Register, abbreviation " HLR "), VLR Visitor Location Register (VisitLocation Register, abbreviation " VLR ") and in AUC's (Authentication Center is called for short " AUC ") obtain customer location registration and the required total data of call request.In addition, MSC is also according to its up-to-date information request of obtaining partial data of new database more.As server, also supporting location registration of MSC, handover, automatic roaming etc. have function and other network function of moving characteristic.
VLR in the gsm system serves the mobile subscriber in its control area, is wherein storing the relevant information that enters registered roaming mobile subscribers in its control area, and the necessary condition of setting up call proceeding is provided for registered roaming mobile subscribers.VLR obtains and stores data necessary from this mobile subscriber's HLR.In case this mobile subscriber leaves its controlled area, then again in another VLR registration, this mobile subscriber's of former VLR deletion blotter data.So VLR can regard a dynamic subscriber's database as.
HLR is the central database of gsm system, is storing mobile subscriber's the related data of all registrations of this HLR control.A HLR can control several mobile switching areas down to whole mobile network, and all mobile subscribers' important static data all is stored among the HLR, comprising data such as identification number of mobile subscriber, access function, class of subscriber and supplementary service functions.Also storage and provide the actual relevant dynamic data of roaming place MSC for MSC among the HLR about the mobile subscriber.Like this, any incoming call all can be delivered to the called subscriber by corresponding route.
Above each several part is formed complete GSM network communicating system, and each several part is interrelated, co-operation.
Yet because gsm system does not relate to Secure Application substantially at first for the public correspondence service, the communication system that the communication system that non-safety is relevant is more relevant is much lower to the requirement of reliability.Along with popularizing of GSM network application, private network or common network group system based on the GSM technical system inevitably are applied to safe related occasion, for example: GSM-R railway private network mobile communication system will be carried Train Control information, because these control informations are used for the control or the monitoring of train, in a single day system goes wrong, gently then cause train mistake class overdue, heavy then may cause safety problem.
Therefore, the high reliability demand that how to satisfy safety-relevant applications becomes based on the private network of GSM technical system or the problem that presses for solution of common network group system.
At present, generally use single net to cover based on the private network or the common network group system of GSM technical system, promptly areal has only one deck network coverage.Private network or common network group system based on the GSM technical system that single net covers comprise a GSM network, this GSM network has its fixing mobile network No. (MobileNetwork Code, be called for short " MNC "), also comprise a HLR, MSC, a BSC, the one or more BTS of this BSC may command.
For the reliability that makes GSM data security application system is protected, strict safety product exploitation related reliability, quality and security control flow process and method for designing, reliability and the safety index requirement very harsh to the equipment proposition of product are adopted in the hardware of single net overlay device or product or software development.Hope ensures the reliability and the fail safe of GSM data security application system by the reliability that promotes single net overlay device.
In actual applications, there is following problem in such scheme: the reliability of GSM data security application system is difficult to ensure, and equipment cost very expensive (because the stringency of development process, the general public network system equipment production efficiency of production efficiency of equipment is obviously low).
Cause the main cause of this situation to be, there are marked difference in the hardware of single net overlay device of GSM or product or software development flow and product design method and the general public communications equipment manufacturer development process and product design method, be difficult to carry out for the general public communications equipment manufacturer, therefore can't reach reliability and safety index requirement to the equipment proposition of product, even reached reliability and safety index requirement, equipment itself also can't solve the integrity problem of eating dishes without rice or wine, and also just can't guarantee the fail safe and the reliability of GSM data transmission in network.And owing to be that single net covers, the data of transmitting in the GSM network do not exist backup or other safeguard measures.
