For the clearer explanation the technology of the present invention of energy, the present invention system describes with the following example:
Above-mentioned wireless communication networks 9 can be common global system for mobile communications (Global System forMobile Communications, be called for short GSM), or the emerging wireless networks such as 3G mobile telephone network, WiMAX and Wi-Fi, this portable electronic devices 91 then can be has the devices such as the mobile phone that carries out communication with global system for mobile communications or have wireless networking capabilities or personal digital assistant, can pass through the Internet 99 as for 90 of servers, or be directly connected on the wireless communication networks 9.In addition, then built the complex data in this database 900 in the server 90 comparison is provided, the details of every data content then can be as shown in the following Table I:
Table one
| 01 | BSIC-01 | ARFCN-01 | CID-01 | Rx-01 |
| 02 | BSIC-02 | ARFCN-02 | CID-02 | Rx-02 |
| 03 | BSIC-03 | ARFCN-03 | CID-03 | Rx-03 |
| ... | ||||
| GPS | LLA |
This data representative is in the relevant information of the measured a plurality of base stations of a coordinate position, 01,02,03 certain three base station that represents in the wireless communication networks 9 for example, and the identification code that represents each base station identity can be represented by BSIC+ARFCN, or is represented by CID separately.And BSIC is the abbreviation of base stationidentity code, be defined in the global system for mobile communications standard in (GSM specification03.03 section 4.3.2.), it is become by 6 bytes, wherein 3 positions are network color code, be called for short NCC, and other 3 positions are base-station color code, be called for short BCC, NCC is allotted by country or international managing body (national or international regulatory authority) usually, and BCC is then allotted by mobile phone dealer (network operator).Then be the abbreviation of Absolute Radio Frequency Channel Number as for ARFCN, it is the channel identification code that adopts for the ease of channel identification in the global system for mobile communications.Therefore, an identification code of this base station identity will just can be become after BSIC and the ARFCN combination.Certainly, also can directly use CID, the namely abbreviation of CellIdentification, it is a unique identification code that is specific to this base station.Then represent signal strength data of measured this base station on this coordinate position as for Rx, the coordinate data in the GPS field then represents via acquisition in the GPS about the longitude of this coordinate position, latitude, highly (LLA).
Complex data in the above-mentioned database 900 can see through many modes and obtain, and go explanation after its details is held again.And the content of utilizing database 900 just can provide the portable electronic devices of the signal that can't receive GPS, for example at indoor portable electronic devices, or itself there is not the portable electronic devices of GPS module to locate accurately.Therefore, this portable electronic devices can send a location request signal, passes to server 90 by this wireless communication networks 9 or the Internet 99, and will include the content shown in the lower tabulation two in this positioning request signal:
Table two
| 07 | BSIC-07 | ARFCN-07 | CID-07 | Rx-07 |
| 08 | BSIC-08 | ARFCN-08 | CID-08 | Rx-08 |
| 03 | BSIC-03 | ARFCN-03 | CID-03 | Rx-03 |
| ... |
Its different longitudes that in table two, do not have in the GPS field that are in from table one, latitude, data such as (LLA) highly, but still relevant for information such as the base station identification code (BSIC+ARFCN or CID) of plurality of base stations in this wireless communication networks 9 and signal strengths, so server 90 just can be according to the content of this positioning request signal, and find out data the highest with the content similarity degree of this positioning request signal in many data from this database 900, and then with the co-ordinate position information in these data, the longitude in the GPS field namely, latitude, altitude information, be returned to this portable electronic devices, and then finish the location of this portable electronic devices.
And above-mentioned similarity degree can select following two kinds of algorithms to finish.Wherein the first algorithm is compared for every data in and the database 900 next according to the identification code of all base stations in the content of this positioning request signal, CID in table one, the table two is as example, the base station 03 that has simultaneously an identical CID in two data, so two signal strength Rx that correspond to base station 03 in the data are carried out correlation operation, and obtain a similarity degree parameter, and such as: difference or squared difference etc. between two signal strengths.Certainly, the base station that also may have simultaneously N identical CID in two data, and N＞1, but after equally N being carried out correlation operation to the signal strength Rx of base station, addition obtains this similarity degree parameter divided by N again, at last regard as the most approaching estimated position for the treatment of with these data in this similarity degree parameter database that minimum value is corresponded to 900, and then with longitude, latitude, altitude information in the GPS field in these data, be returned to this portable electronic devices, and then finish the location of this portable electronic devices.
Then be to utilize the size order of signal strength Rx to compare as for second algorithm, the base station that for example in two data, has simultaneously N identical CID, and also identical corresponding to the size order of the signal strength Rx of base station, just it can be considered as the candidate, selecting at last N in all candidates is the corresponding data of maximal value, if data have many, can decide a document according to the first algorithm again, and then with the longitude in the GPS field in these data, latitude, altitude information, be returned to this portable electronic devices, just can finish the location of this portable electronic devices.
In addition, for refinement true, one first threshold value can be set in the first algorithm, finish estimation if can not find the similarity degree parameter less than the data of one first threshold value, just expression does not have data applicable, so just can relax scope, uses instead less than many data of one second threshold value and estimates, extrapolate at last a position again and finish the location, wherein the second threshold value is greater than this first threshold value.Equally, in second algorithm, also have the situation that obtains many data.At this moment, the algorithm that utilizes many data to estimate an estimated position just need to be used, and this algorithm can be finished in server end, or many data back are estimated all can to portable electronic devices.But finish in the algorithm described in the application case of No. 097150480 " location householder method and the positioning auxiliary device that uses the method " of application on Dec 14th, 97 as for this algorithm request for utilization people who utilizes many data to carry out location estimation, so do not repeat them here.
And from the above, data bulk in the database 900 is more, will be so that positioning result be more accurate, therefore this case can select any mode of following three kinds of modes or its combination in any to obtain, first kind of way is to be produced by the portable electronic devices 91 that user itself holds, and each just sends one every a period of time, owing to have GPS module 910 and global system for mobile communications module 920 on this portable electronic devices 91, the signal that sends in order to the receiving world locational system Satellite of GPS module 910 wherein, and calculate according to this accurate positional information, i.e. above-mentioned longitude, latitude, highly (LLA); Global system for mobile communications module 920 is then in order to being connected with at least one base station settling signal in the wireless communication networks 9, and then obtains the identification code (BSIC+ARFCN or CID) of each base station identity and the signal strength data (Rx) of this base station.Thus, collect the database 900 of the historical track data that portable electronic devices 91 is arranged, just can work as portable electronic devices 91 and move in the signal that to receive GPS, provide this portable electronic devices 91 to position.
But, when this portable electronic devices itself does not have GPS module 910, or being in indoor once starting shooting and not receiving the signal that the GPS Satellite sends, the historical track data that will be difficult to itself this moment can be for reference.Therefore the second way then is to be produced by arbitrary portable electronic devices that can be connected with wireless communication networks 9 settling signals, be not limited to the portable electronic devices that user itself holds, but this portable electronic devices have GPS module and global system for mobile communications module equally.Therefore, on the position that can receive global positioning system signal and global system for mobile communications signal, regularly produce this data, and then this database 900 that sends in this server 90 stores.
If do not want again to allow this database 900 unrestrictedly record the data that all portable electronic devices produce, or during near the complex data when portable electronic devices can not find some base stations in server 90, just can utilize the third method, be that server 90 sees through wireless communication networks 9 near other at least one portable electronic devices this base station is claimed, make this portable electronic devices return again as shown in Table 1 positional information and store with using and get final product.
In addition, more can record the time point that data generate in these data, owing to may have many data to be recorded at same position, and by the comparison time point, can keep up-to-date data and superseded legacy data.
Comprehensive above technical descriptioon, we can know and recognize, the wireless signal that utilizes portable electronic devices to receive to be sent by wireless communication networks and receive the positioning signal of being sent by global position system, and the base station identification code that acquires and signal strength information and positional information are stored, thereby set up a database and enter into for the user and position can't receive global position system regional the time, really solve the disappearance of prior art means, and then finished development topmost purpose of the present invention.
In addition, the above is preferred embodiment of the present invention only, be not to limit claim of the present invention, and technological thought of the present invention also can utilize frequency shift (FS) to cause the mode of phase change to finish except can utilizing signal strength information.Hereat, the present invention must be thought and is to modify the protection domain of right neither disengaging claim as all by the personage Ren Shi craftsman who knows this skill.
