Description

The combined positioning method of one-touch Personal Handyphone System locating terminal and fixed CDMA WLL

Technical field

The present invention relates to a kind of PHS mobile phone and many base stations multi-parameter localization method, relate in particular to the combined positioning method of a kind of one-touch Personal Handyphone System locating terminal and fixed CDMA WLL.

Background technology

At present, the Personal Handyphone System of prior art and landline telephone are independently in product physical aspect and use.PHS mobile phone realizes radio communication and transfer of data by the PHS base station network, and landline telephone is realized wire communication and transfer of data by fixed telephone network.The mechanism of known Personal Handyphone System location is:

Single base station locate mode, the base station location by inquiry and current talking obtains the base station location that current Personal Handyphone System lands, as the position location of Personal Handyphone System;

Many base stations locate mode sends 3-30 basic station number and corresponding base station field intensity by Personal Handyphone System to background server, by certain position algorithm, calculates the position of Personal Handyphone System;

Locate mode is made up with many base stations in single base station, adopts many base stations locate mode for possessing the Personal Handyphone System that basic station number more than 3 and base station field intensity information are sent to the back-end data library facility, otherwise the Personal Handyphone System that does not possess this function is with single base station locate mode.

The Location Mechanism of the landline telephone of prior art is to obtain installation addresses and with the position location of installation addresses as landline telephone by inquiry fixed telephone subscriber mount message database mode.

The Personal Handyphone System location and the landline telephone location of prior art are fully independently.Because the introduction of fixed CDMA WLL QBox function makes Personal Handyphone System and landline telephone can well combine for voice communication.The fixed CDMA WLL QBox function of prior art refers to a kind of a kind of signal optimizing scheme to Personal Handyphone System that telecommunications is released, by between Personal Handyphone System and landline telephone, adding radio communication device and communications protocol, make Personal Handyphone System can form a privately owned wireless communication networks with fixed line at home, when the user carries out communication by Personal Handyphone System, can utilize this privately owned wireless communication networks, go out by landline telephone, carry out communication, Personal Handyphone System during this time function is equivalent to cordless telephone, and outside private network, be existing normally Personal Handyphone System function.

The Personal Handyphone System of prior art does not have the button that can be used for seeking help, and there is following shortcoming in many base stations of Personal Handyphone System multi-parameter localization method:

1. traditional Personal Handyphone System location algorithm can only provide near about the 80 meters positioning accuracy of being in, because positioning accuracy is low, for rescue and other service provide very big not convenient.

Because traditional developing from pas network because signal strength signal intensity a little less than, install and owner's difficult coordination the base station, uses inconvenience.

3. the Personal Handyphone System locating platform of prior art is after PHS mobile phone is connected, because channel is occupied, the Personal Handyphone System locating platform can't be known the information of putting to the present bit that rescue center sends Personal Handyphone System.

Summary of the invention

2.1 locating platform according to the emergency number of call center to one-touch Personal Handyphone System locating terminal, in the mount message storehouse of the fixed CDMA WLL from locating platform, is searched the installation site information of this emergency number;

2.2 locating platform inquires the installation site of the one-touch Personal Handyphone System locating terminal of this emergency number, then the current location of this position as the one-touch Personal Handyphone System locating terminal of emergency number, feeds back to the call center;

2.3 if locating platform does not inquire the installation site of the fixed line of this one-touch Personal Handyphone System locating terminal, then judge the emergency number that this emergency number is one-touch Personal Handyphone System locating terminal.

2. the combined positioning method of one-touch Personal Handyphone System locating terminal according to claim 1 and fixed CDMA WLL is characterized in that: further comprising the steps of in the described step 3,

3.1 locating platform calls the Personal Handyphone System customer data base and according to 1.3 step execution results, the i.e. numbering of this one-touch Personal Handyphone System locating terminal peripheral base station and field intensity information, the many base stations of employing Personal Handyphone System add the formula of field intensity, calculate the position of the one-touch Personal Handyphone System locating terminal of this emergency

It is as follows that the many base stations of Personal Handyphone System add the formula of field intensity:

Longitude:

$\mathrm{long}=\frac{F1\mathrm{lomg}1}{(F1+F2+F3+F4+F5)}+\frac{F2\mathrm{long}2}{(F1+F2+F3+F4+F5)}+......+\frac{F5\mathrm{long}5}{(F1+F2+F3+F4+F5)}$

Latitude:

In the formula: F1...F5 represents to ask the field intensity of 5 base stations,

Long1...long5 represents 5 base station longitudes separately,

Long represents the longitude of the one-touch Personal Handyphone System locating terminal that calculates,

Lat1...lat5 represents 5 base station latitudes separately,

Lat represents the latitude of the one-touch Personal Handyphone System locating terminal that calculates.

3. the combined positioning method of one-touch Personal Handyphone System locating terminal according to claim 1 and fixed CDMA WLL is characterized in that: further comprising the steps of in the described step 3,

3.2 after locating platform calculates, form bit string and feed back to the call center, the call center shows the current location of this one-touch Personal Handyphone System locating terminal on monitoring screen simultaneously.

4. the combined positioning method of one-touch Personal Handyphone System locating terminal according to claim 1 and fixed CDMA WLL is characterized in that: further comprising the steps of in the described step 4,

4.1 the failure of locating platform feedback calculation, then expression can not find the position of this one-touch Personal Handyphone System locating terminal, and the information of locating platform feedback location failure is issued the call center, by call center's otherwise processed.

5. one-touch Personal Handyphone System locating terminal that uses the combined positioning method of one-touch Personal Handyphone System locating terminal according to claim 1 and fixed CDMA WLL, comprise casing, be arranged on the casing top display, be arranged on the casing below keyboard, be arranged on the casing top antenna, be arranged on " one " key treatment circuit in the casing; It is characterized in that: be provided with " one " key in the described keyboard, should be connected with " one " key treatment circuit by " one " key, after one-touch Personal Handyphone System is pressed " one " key button with the head of a household, locating platform is by judging caller ID, if landline telephone then obtains positional information from the address in phs telephone user's data storehouse, if PHS mobile phone, then, calculate the positional information of the one-touch Personal Handyphone System of determining incoming call by one-touch Personal Handyphone System navigation system.
