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

The object of the present invention is to provide the combined positioning method of a kind of one-touch Personal Handyphone System locating terminal and fixed CDMA WLL, can improve the Personal Handyphone System sensitivity of signal framing at home, the signal transmission is reliable, is convenient to distress call and uses.

The objective of the invention is to be achieved through the following technical solutions: one-touch Personal Handyphone System locating terminal, comprise casing, be arranged on 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; Be characterized in, be provided with " one " key in the described keyboard, should be connected with " one " key treatment circuit by " one " key.

Adopt the combined positioning method of one-touch Personal Handyphone System locating terminal and fixed CDMA WLL, be characterized in, this combined method may further comprise the steps,

Step 1, the call center sends certain terminal location request of location; Step 2, locating platform by the Location Request of receiving the call center after, handle; Step 3 adopts the Personal Handyphone System location algorithm, the position of calculating one-touch Personal Handyphone System locating terminal; Step 4 after the positional information of call center by the one-touch Personal Handyphone System locating terminal that receives emergency, sends to rescue facility and provides the service of seeking help for this user.

The above-mentioned one-touch Personal Handyphone System locating terminal and the combined positioning method of fixed CDMA WLL are characterized in, and be further comprising the steps of in the described step 1,

1.1 one-touch Personal Handyphone System locating end-user is pressed the alarm key, this one-touch Personal Handyphone System locating terminal judges whether private network has the frequency signal of fixed CDMA WLL;

1.2, then pass through fixed CDMA WLL call establishment center by one-touch Personal Handyphone System locating terminal if any the frequency signal of fixed CDMA WLL;

1.3 do not receive the frequency signal of fixed CDMA WLL, then add a synthetic bit string note of field intensity in locating platform by the base station numbering by the transmission earlier of one-touch Personal Handyphone System locating terminal;

1.4 after the call center received the calling of one-touch Personal Handyphone System locating terminal, the position requests that sends this one-touch Personal Handyphone System locating terminal of inquiry was instructed locating platform.

The above-mentioned one-touch Personal Handyphone System locating terminal and the combined positioning method of fixed CDMA WLL are characterized in, and be further comprising the steps of in the described step 2,

2.1 locating platform according to the calling for help number of call center to the request of 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 calling for help 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 number that this emergency number is one-touch Personal Handyphone System locating terminal.

The above-mentioned one-touch Personal Handyphone System locating terminal and the combined positioning method of fixed CDMA WLL are characterized in, and be further comprising the steps of in the described step 3,

3.1 according to 1.3 steps, locating platform calls the numbering and the field intensity information of Personal Handyphone System customer data base and this one-touch Personal Handyphone System locating terminal peripheral base station, 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:
