1. dynamic difference localization method of a kind of mobile communication terminal based on map match, it is characterised in that:

  • Comprise the following steps:

    S1, mobile communication terminal scan all communication channels and obtain the information of peripheral base station, including mobile country code MMC,Mobile network code MNC, base station number CID, LAC, the base station information of the signal intensity RSSI for receiving;

    S2, the base station information according to acquisition, using the latitude and longitude coordinates of base station information database lookup peripheral base station point;

    S3, according to wireless channel model, the signal intensity of peripheral base station and its latitude and longitude coordinates, calculate the warp of mobile communication terminalLatitude coordinate;

    S4, the latitude and longitude coordinates according to mobile communication terminal, mark its position in map, remove and deviate fitting track more than settingAfter the historical position coordinate of definite value, remaining historical position is fitted to form movement locus;

    The deflection of the road of the be fitted movement locus of S5, contrast and map and range difference, mate immediate street road,And reject the larger location point of the mated road of deviation on movement locus;

    S6, it is repeated cyclically above step S1 ~ S5.
