Description

The mobile phone that has destination prompting function

Technical field

The utility model relates to a kind of positioning indicating mobile phone, especially a kind of mobile phone that has destination prompting function.

Background technology

The vehicles as bus, subway etc., are present social people's work, the requisite trip mode of living.But the passenger may be very strange to road, do not know its position, and a lot of vehicles have brought very big trouble because of the inaccurate passenger's of the giving riding public transportation means of not calling out the stops or call out the stops.And, the timely vehicles function of calling out the stops, the passenger must notice constantly that also calling out the stops of the vehicles just come great inconvenience.

For example: can find a lot of people all in sleep when we take public transport, may be because tired out or boring or the like reason. but also have the people can because sleep do when missing the stop.

The utility model also uses following prior art:

The function of GSM mobile handset location is widely used at present, utilizes this characteristics, can increase a destination prompting function above the mobile phone.The distance or the time of objective and prompting are set on the mobile phone.Reached set point when the setpoint distance or the time in distance objective place, mobile phone is made and is reminded action.

GSM full name is: Global System for Mobile Communications, Chinese is global system for mobile communications, be commonly called as " Global Link ", it is a kind of mobile communication technology standard that originates from Europe, it is second generation mobile communication technology, its exploitation purpose is to allow all parts of the world can use a mobile telephone network standard jointly, allows the user use a mobile phone just can manage it all over the whole world.At present, China Mobile, CHINAUNICOM respectively have a GSM net, are mobile communications network the biggest in the world.Gsm system comprises several frequency ranges such as GSM 900:900MHz, GSM1800:1800MHz and GSM1900:1900MHz.GSM also is that the English of Guanghua School of Management under the Peking University (Guanghua School of Management) is called for short.

The GSM mobile handset locate mode can be divided into mode Network Based and usually based on two kinds of terminal modes.The time of advent (TOA) be can be divided into technically, Measuring Time poor (E-OTD) and auxiliary (A-GPS) the 3 kinds of modes of GPS strengthened.

1, TOA location technology

The TOA locate mode can realize that mobile phone need not to do any change on existing any mobile phone.

The specific implementation step:

(1) mobile phone that will locate sends a known signal, and three or receive this signal simultaneously more than three LMU, known signal is the access burst signal that mobile phone sends when carrying out asynchronous the switching;

Absolute GPS when (2) each LMU obtains signal arrival can obtain relative time poor (RTD) after the time;

(3) according to the information of first two steps, SMLC compares in twos, calculates the burst time of advent poor (TDOA), draws the exact position, and gets back in the application.To draw the mobile phone exact position by triangulation calculation, must know the geographical position of two other parameter: LMU and the time offset between each LMU.Each LMU absolute GPS time that must provide for example, or place in the place of known location and can obtain real time poor (RTD) parameter with reference to LMU.

LMU determines TOA with the access burst signal.When Location Request was sent, LMU was chosen, and disposed correct frequency, so that receive the access burst signal.At this moment, mobile phone reaches 70 with the certain power transmission and inserts pulses (duration 320ms) on Traffic Channel (may be in the frequency hopping mode).Each LMU is accomplished in several ways and improves the measurement result of TOA.The burst that utilization is received can improve measures the probability of success and certainty of measurement.Adopt diversity technique (as antenna diversity and frequency hopping), can reduce the influence of multipath effect, improve certainty of measurement.When certain application need was known mobile phone location, this application was sent request to SMLC, informed phone number and positioning accuracy request simultaneously.SMLC is together gathered and sent to measured TOA parameter and error amount thereof, and according to these data, SMLC can calculate and use needed mobile phone location, again positional information and error range is sent it back application.

The TOA locate mode needs additional firmware (LMU), to reach the accurate Calculation burst purpose of the time of advent.Implementation has multiple: LMU both can be integrated in the BTS, also can be used as specific installation.LMU both can have independent antenna during as specific installation, also can share antenna with BTS, realized inter-net communication by air interface.

2, E-OTD location technology

The E-OTD locate mode is from Measuring Time poor (OTD) development, and OTD refers to measure the time quantum of gained, and E-OTD refers to the mode measured.Mobile phone need not additional any hardware just can obtain measurement result.For Synchronization Network, the relative time of advent of the several BTS signals of mobile phone for measuring; For non-synchronous network, signal also needs to be received by the LMU of a location aware simultaneously.Determined the signal transmission time of BTS, then can determine the geometric distance between BTS and the mobile phone, and then calculated, finally determined the position of mobile phone according to this distance to mobile phone.

Performing step is as follows:

1) mobile phone receives that each base station sends signal, obtains the TOA parameter; LMU obtains the RTD parameter;

2) mobile phone is sent to the GSM net with TOA and RTD parameter.

3) OTD measure to need with synchronously, the pulse of standard and simulation.The frame that sends as BTS is not when synchronous, and network need be measured the RTD between the BTS.In order to carry out accurate triangulation, OTD measures and RTD measurement when BTS (asynchronous) all needs 3 BTS.After obtaining the OTD parameter, mobile phone location both can calculate in network, also can calculate (requiring mobile phone to possess various necessary informations) in terminal.The former is called the mobile phone supplementary mode, and the latter is called mobile phone from master mode.

By the position counting function module in mobile phone or the network, realize position calculation.

3, A-GPS principle

GPS assist location mode performing step is as follows: the GSM net is received the GPS supplementary; The GSM net sends to mobile phone with supplementary; Mobile phone obtains GPS information, calculates and draw self exact position; Mobile phone sends to the GSM net with positional information.

This mode has mobile phone supplementary mode and mobile phone from two kinds of master modes:

(1) mobile phone assistant GPS locate mode

This solution is most of function of traditional gps receiver to be transferred on the network processing unit realize.This mode needs equipment such as antenna, RF unit and data processor.The GSM net sends a string extremely short supplementary to mobile phone, comprises time, satellites in view inventory, satellite-signal Doppler parameter and code phase search window.These parameters help built-in GPS module to reduce the gps signal acquisition time.Auxiliary data is from the pseudorange data that produces after the cellphone GPS resume module, and sustainable several minutes.After receiving these pseudorange data, corresponding network processing unit or location-server can roughly estimate the position of mobile phone.After the GSM net increases necessary correction, can improve positioning accuracy.

(2) the autonomous GPS locate mode of mobile phone

This mobile phone comprises a Full Featured gps receiver, has all functions of mobile phone in (1) mode, adds satellite position and mobile phone location computing function.When computing began, the data that need were more than the mobile phone supplementary mode, and these data can continue more than 4 hours or upgrade as required, generally include time, reference position, satellite ephemeris and time check parameter etc.If the precision that some application need is higher then must continue (about 30s at interval) and send out differential GPS (DGPS) signal to mobile phone.The DGPS signal is effective at the territorial scope of non-constant width, is the territorial scope that broad can be served in the center with a parametric receiver.Final position information is calculated by mobile phone itself, if need, this locating information can send in other any application.
