Description

A kind of definite method and device of position range of portable terminal
Technical field
The present invention relates to the portable terminal field of locating technology in the wireless communication technology field, relate in particular to a kind of definite method and device of position range of portable terminal.
Background technology
At present in the location-based service of cordless communication network; The scheme that has a kind of position according to the base station location localisation of mobile terminals; Promptly, inquire about the Cell-ID of preset base station and the corresponding relation of base station location, determine the position of this base station in service sector according to the cell identification code Cell-ID of portable terminal current service cell to be positioned base station; And with the position of the base station of determining positioning result as this portable terminal to be positioned; This location technology is also referred to as the base station location technology, and this technology can be divided into the foundation of off-line Cell-ID database and two stages of online location from implementing principle and treatment step, wherein:
Off-line Cell-ID database to set up flow process as shown in Figure 1, comprising:
Step S101, sampling terminal measure the Cell-ID of base station in service sector in each sample point of preset sufficient density, promptly determine the corresponding Cell-ID of each sampled point.
Step S102, confirm the position coordinates (longitude, dimension and height etc.) of each sampled point simultaneously, specifically can confirm through modes such as GPS location or address registration.
The position coordinates of each sampled point that step S103, integration are determined, and carry out certain pretreatment operation, the record of the sampled point that for example the delete position coordinate is close.
Step S104, based on the position coordinates of all corresponding sampled points of each Cell-ID after the pretreatment operation; Through position cluster or triangle location Calculation; Confirm the position coordinates of each Cell-ID respective base station, promptly set up the corresponding relation of each Cell-ID and base station location.
Step S105, each Cell-ID that will collect and the corresponding relation of foundation are stored in the Cell-ID location database, are used for follow-up online positioning stage and use.
The flow process of online location is as shown in Figure 2, comprising:
Step S201, confirm the Cell-ID of the current service cell of portable terminal to be positioned.
Step S202, based on the corresponding relation of Cell-ID and base station location in the Cell-ID inquiry Cell-ID location database of confirming, determine the position of this Cell-ID respective base station, and with the positioning result of this base station location as this portable terminal to be positioned.
The position of the portable terminal of orienting in the such scheme; Essence is the position of the home base station of this portable terminal; Promptly compare the physical location of this portable terminal; Have certain error, and this error is that this distance range is also referred to as error range in the scope of the position of this portable terminal home base station; Change an angle; Can think that also the positioning result of the portable terminal that essence is determined not is a location point accurately; But position range; Promptly determining this portable terminal is in the position with this base station is a border circular areas in the center of circle, also can be elliptic region under few situation.For describing conveniently, the describing mode of the position range of following adopted localisation of mobile terminals (i.e. the error range of location) is described.
Therefore; Except that the position of the portable terminal home base station that adopts such scheme to obtain as the positioning result; If also comprise a position range of the position of this base station relatively in the positioning result, then can more comprehensively characterize the positional information of portable terminal, help strengthening the specific aim of location-based service.
In the existing above-mentioned scheme based on base station location localisation of mobile terminals position; Proposition is at off-line Cell-ID database establishment stage; Also determine the position range corresponding, promptly set up the corresponding relation of Cell-ID and position range, for example with each Cell-ID; Position range is that the center of circle is the border circular areas scope of radius at a certain distance for the position with the base station; Specifically can be with the mean value of the distance between the position of each sampled point corresponding and this Cell-ID respective base station with Cell-ID, as the radius of the corresponding position range of this Cell-ID, perhaps determine in each corresponding sampled point of Cell-ID sampled point with the furthest of the position of this Cell-ID respective base station; And with this distance of the position of sampled point and this Cell-ID respective base station farthest, as the radius of the corresponding position range of this Cell-ID.Accordingly, in online location process, when can determine the position of respective base station, also determine corresponding position range, as the positioning result of portable terminal location according to Cell-ID according to Cell-ID.
Though, only compare the positioning result of the base station location of determining as the portable terminal location, in positioning result, increase position range after; Can more comprehensively characterize the positional information of portable terminal, but the position range of the portable terminal that such scheme is determined, be equivalent to the coverage of portable terminal home base station in fact; Continuous development and innovation along with location service; And for the user provides the demand of more diversified demarcation of location service, location application requires increasingly highly to basic stationkeeping ability, and position capability constantly develops towards the direction of opening, intelligence; Requirement to the accuracy of portable terminal location is also higher; So, confirm that based on base station location the accuracy of position range of portable terminal is lower in the prior art, can't satisfy existing business demand.
For example, have only a unique position range to the base station of each sub-district, under the situation of the close together between portable terminal to be positioned and the base station location, the accuracy of the positional information of the portable terminal that position range characterized out that this is unique is lower.
