Network service district described in the embodiment of the present invention can pointer to all Serving cells in a regional networking, wherein regional changeable, needs according to the network optimization are determined, can be such as all Serving cells in Shenzhen's networking, also can be Shenzhen district's networking in all Serving cells.The present embodiment is described for the network optimization of Shenzhen, and the principle in other areas is identical.
Preferably, a update cycle can be set, all data of network service district in each update cycle be processed respectively, the thresholding of dynamic indoor and outdoor business datum can be obtained like this.The length of update cycle can set as required, such as, can be one day, one week etc.The present embodiment was described for one of them cycle, the business datum within the scope of the present embodiment hereinafter described all business datum Jun Zhi Shenzhen networkings in the update cycle.
Exemplary, each business datum comprises Received signal strength measured value and locating information, wherein, described Received signal strength measured value represents the size of the signal that the actual base station received of terminal sends, can with different Parametric Representations in different applications, such as, universal mobile telecommunications system (Universal Mobile Telecommunications System, be called for short UMTS) in, Received signal strength measured value can be received signal code territory (Received Signal Code Power, be called for short RSCP), at Long Term Evolution (Long Term Evolution, be called for short LTE) in technology, Received signal strength measured value can be Reference Signal Received Power (Reference Signal Receiving Power, be called for short RSRP), at global system for mobile communications (Global System For Mobile Communications, be called for short GSM) in, Received signal strength measured value can be received signal level (Received Signal Level, be called for short RXLEV).The present embodiment is described for the RSCP in WCDMA technology, but the present embodiment does not restrict the technical field of the present invention's application and the design parameter of Received signal strength measured value representative.
Locating information can comprise global positioning system (Global Positioning System, be called for short GPS) locating information, the general principle of GPS location is as known known date according to the satellite instantaneous position of high-speed motion, adopt the method for space length resection, determine the position of tested point.The method of GPS location is diversified, and can adopt different localization methods according to different purposes, the present embodiment is not construed as limiting this.
Or, utilize the information of the time of advent (Time of Arrival is called for short TOA) localization method, the time of advent poor (Time Difference of Arrival is called for short TDOA) localization method.Such as comprise the Loop Round Trip Time (Round Trip Time be called for short RTT) of at least three communities to terminal.
Wherein, the general principle of TOA is, TOA represents that the signal between terminal and community propagates duration (RTT/2), and the speed that radio wave is propagated in atmosphere is light velocity c, and therefore the distance of community and terminal is c* (RTT/2).Utilize the distance between at least 3 communities and terminal, just can draw the position of terminal according to three limit positioning principles.
TDOA is the innovatory algorithm of TOA.TDOA still adopts the mode according to time Estimate distance, with TOA unlike, TDOA represents that the propagation duration of signal between terminal and Liang Ge community is poor, just can obtain the difference of the distance of terminal and Liang Ge community according to the product of light velocity c and the propagation duration difference between terminal and Liang Ge community.Because the difference of the distance of 2 equals a constant, this meets hyp characteristic, utilizes 3 communities can obtain 3 hyperbolas, these 3 hyp intersection point position locations (also only can consider two hyperbolas wherein).
Exemplary, calculation server can receive the MR data that data acquisition equipment gathers from network, then according to MR data acquisition service data.
MR data are important means that network side obtains terminal wireless information, mainly comprise two parts: upward signal information and downstream signal information.
Exemplary, downstream signal information is measured by the network terminal and is gathered, and reports data acquisition unit by measurement report (Measurement Report) signaling of eating dishes without rice or wine; Upward signal information is measured by the base transceiver station (Base Transceiver Station is called for short BTS) of network side and is gathered and report data acquisition unit.
MR data can comprise RSCP measured value, GPS information.
Because the MR data of data acquisition unit acquires carry out the different piece of automatic network, calculation server obtains business datum after the MR data of same terminal, a same business can being arranged.
Business datum can store with form or other forms, namely can be stored in calculation server, also can be stored in other storage elements and use for calculation server.
S202: business datum described in each is corresponded to a network grid by the locating information according to described business datum;

Exemplary, the RSCP theoretical value of described network grid is according to the RSCP value in the described network grid of propagation model acquisition.Each network grid belongs to a main Serving cell, also has neighbor cell.Can the RSCP transmitted value of each main Serving cell pre-recorded.
According to the locating information of business datum, this business datum is corresponded to a network grid and can have multiple implementation method, exemplary, can comprise:
The calculating location coordinate that each business datum described in correspondence occurs is determined according to the locating information of each business datum;
The calculating location coordinate that business datum described in each occurs is mated with the position coordinates in the network grid map comprising multiple network grid, determines the network grid that business datum described in each is corresponding.
Exemplary, calculation server locates each business datum according to the location fixed interest inside each business datum.
GPS location utilizes at least 4 satellite-signals to determine the position of terminal, and current GPS can reach the positioning precision within ten meters.But, because GPS location depends on catching and receiving satellite-signal, and under indoor environment, be difficult to the signal receiving position location satellite, cause GPS to locate cannot normally use, so, preferably, if containing GPS locating information in business datum, utilize GPS to locate business datum, if business datum inside does not have GPS locating information, then according to the method for RTT Information Pull TOA or TDOA, business datum is positioned, obtain the coordinate of each business datum, preferably, the coordinate of business datum can represent with longitude and latitude.

Exemplary, calculation server can pre-set the propagation model of network service district, in practical application, because the wireless propagation environment in each province, city varies, such as, be in the city of knob compared with the city being in plains region, its communication environments has a great difference, so both propagation models also can exist larger difference.Therefore, preferably, the propagation model of network service district can be determined in Combining with terrain, landforms, building, the isoparametric impact of vegetation.
Such as, propagation model can be RSCP=RSCP
0-[128.1+37.6log10 (D)],
Wherein, RSCP is theoretical value, RSCP
0for transmitted value, 128.1+37.6log10 (D) is path loss (Path Loss is called for short PL), and D is the distance of base station and terminal, and unit is km.
According to propagation model, the RSCP theoretical value in each network grid of network service district can be obtained, exemplary, when calculating the RSCP theoretical value of one of them specific network grid, can determine according to the numbering of network grid the main Serving cell that network grid belongs to, and then the RSCP of main Serving cell can be obtained
0, utilize the RSCP transmitted value of main Serving cell and main Serving cell to the distance D of this network grid, the RSCP theoretical value of this grid can be calculated according to propagation model.In addition, according to computing capability and the storage capacity of calculation server, the RSCP theoretical value of each network grid can precalculate and obtains and store, and also can calculate in real time.
According to the propagation principle of wireless signal, the aerial loss of signal and through the loss difference of building apart from larger, so, place and identical reception place are transmitted for same radio, the RSCP value difference of the signal that indoor and outdoors receives.So the difference of the RSCP theoretical value in a network grid and the penetration loss of this area's building can as the foundation determining indoor business datum and outdoor service data threshold.
