Embodiment
Below in conjunction with Figure of description and embodiment the present invention is done further detailed description.
Fig. 1 shows the flow chart of a kind of simulation base station localization method based on the A interface signaling of the present invention, and this method may further comprise the steps:
Step S11: gather the signaling of A interface, generate call detail record through server, and add in the signaling data storehouse;
The A interface definition is the communication interface between network subsystem (NSS) and base station sub-system (BSS).From system, be exactly the interface between mobile switching centre (MSC) and the base station controller (BSC).The information of this interface transmission comprises travelling carriage management, BTS management, mobile management, connection management etc.
Call detail record (CDR; Calling detail records) overall process of call proceeding has been described; The parameter that in CDR, writes down comes from original signalling message data; Comprise and relevant data content is upgraded in the position, through some important parameters in the record are further analyzed and handled, the basis of analysis can be provided for fixed-line telephone network or mobile phone network service.Among the present invention through gathering the signaling of A interface in the GSM network, through server collect, decoding, association analysis generate call detail record CDR, and add in the signaling data storehouse.
Step S12: the information in the signaling data storehouse is carried out association analysis, obtain statistic analysis result;
The association analysis of indication refers to the A interface signaling that is collected according to step S11 in this execution mode; To wherein decoding and gathering with the position relevant signaling content of renewal; Summary information mainly comprises original position district sign indicating number, reposition district sign indicating number, new cell ID and position update times, and the purpose of analysis is to obtain original position district and the number of times of reposition district occurrence positions renewal and the number of times that quarters at new sub-district under the reposition district.Comprise original position district sign indicating number, reposition district sign indicating number and position update times in the statistic analysis result.The call detail record that interface signaling generated to gathering carries out statistical analysis, and the statistics that obtains in the call detail record upgrading with the position recording-related information is existing technological means, no longer too much detailed introduction in this execution mode.
The variation of Location Area Code has embodied the mobility of mobile communication GSM network, and a lane place is exactly a zone in the network, and a general GSM network can be made up of some lane place.When caller mobile phone dialing called mobile phone, network is the general areas according to lane place location called mobile phone, and orders to the base station under this lane place at distributing paging and to search out called mobile phone.All there is a unique numbering each lane place in network, Here it is Location Area Code is when mobile phone switches the branch that original position district sign indicating number and reposition district sign indicating number have just been arranged when being registered to another lane place from a lane place.
Step S13:, obtain near the normal cell tabulation of simulation base station according to statistic analysis result;
According to the statistic analysis result that obtains among the step S12, combing goes out the simulation base station Location Area Code, and normal cell is tabulated near obtaining simulation base station.So-called simulation base station be exactly near the network cell simulation base station of non-moving common carrier construction normal cell be meant by the position of simulation base station Location Area Code and upgrade the sub-district under the Location Area Code in the moved back communication network; Just the reposition district sign indicating number that returns of cell update is the Location Area Code in the mobile communications network, promptly is the legitimate network sub-district of mobile communication carrier's construction.
Collection through A interface signaling data; Location Area Code known in the mobile communications network number is investigated all Location Area Codes in the statistic analysis result number (comprising reposition district sign indicating number and original position district sign indicating number); Can grasp Location Area Code all in the non-moving communication network number; Near non-moving communication network lane place, filter out normal cell then; Obtain the normal cell tabulation, as shown in table 1 below, near simulation base station, comprised original position district sign indicating number, reposition district sign indicating number, new cell ID CI and position update times in the normal cell tabulation; A retention position update times has only kept the sub-district of renewal more than 100, position in tabulation greater than the sub-district of set point in the normal cell tabulation in this embodiment near simulation base station.Reservation is to cut down the length that normal cell is tabulated greater than the purpose of set point, gets rid of indivedual positions and upgrades few sub-district accidentalia, improves accuracy, and set point can increase and decrease according to the network actual conditions.
