Can also be on the basis of the enclosure space forming by any regular cutting earth surface or the above space of earth surface, more further with the time, each enclosure space having formed be carried out to cutting, each sealing time empty interval as a subregion.
Described point of territory is on the basis of described subregion, carries out territory division according to wireless signal coverage, and each point of territory is put together by multiple adjacent subregions.
According to above-mentioned subregion, point domain model, getting after the locating information of said apparatus, just can, according to locating information and predeterminable area recognizer, calculate the area information obtaining.Above-mentioned predeterminable area recognizer, comprise subregion recognizer and point territory recognizer, described region recognizer is on the basis in described subregion, point territory, definition and default for identifying described device in certain concrete subregion and point territory, and the operation method that calculates this partition information, divides domain information.
Taking two dimension as example, consider longitude and latitude, in above-mentioned predeterminable area partitioning algorithm, carry out directly setting in the algorithm of subregion the division interval of longitude and the division interval of latitude, for example longitude at interval of 10 degree divide once, latitude divides once at interval of 10 degree, being easy to can be just multiple quadrilateral areas by earth cutting.Each district, the territory divided can show with characteristic point coordinate, for example, represent with their center point coordinate.For improve precision can by region divide as far as possible little.
Above-mentioned subregion is embodied in, and according to the direction of terrestrial meridian and parallel, earth surface is carried out to cutting, with reference to Fig. 2, be divided into lattice every d degree, earth surface is divided into n lattice quadrangle, for example, the earth is regarded as to the spheroid of a standard, n=360 degree/d degree so, n is integer, form the quadrangle interval of m sealing, be the P1 shown in Fig. 2, P2, P3 ..., Pm, known m=n × n, wherein Px represents arbitrary district.Arbitrary district can select its characteristic point coordinate to represent, can select quadrangle central point coordinate to represent subregion, and each subregion has one group of definite latitude and longitude coordinates, for example: the central point longitude and latitude coordinate of P1 is expressed as (x1, y1).In region identification block 102, default above-mentioned zoning ordinance and characteristic point are described the method for subregion, can calculate fast partition information.
On the basis of above-mentioned subregion, carry out territory division according to the wireless signal coverage of communication node (regarding said apparatus as a communication node), the wireless signal coverage of general communication node is a circle, if taking circle as a territory, cannot carry out seamless cutting, because can not reach laminating completely between circle and circle, therefore in the embodiment of the present invention, in the circle covering at wireless signal, for example get maximum regular polygon, as a territory: get equilateral triangle, square, regular hexagon etc.With reference to Fig. 3, wherein circle is the wireless signal coverage of one of them communication node, and middle triangle is a maximum equilateral triangle Q who gets in this circle, and this Q is a territory, and similarly, around other each triangle is a territory.
Equally, with reference to Fig. 4, wherein each square is a territory.With reference to Fig. 5, wherein each regular hexagon is a territory.It should be noted that, a territory can cover multiple districts.
No matter divide territory in any mode, can spread since the central point of a regular polygon to surrounding, mark off r territory, each territory also can select the coordinate of its characteristic point central point to describe, each territory central point can calculate and try to achieve (wherein, L is regular polygon limit number, and R is the radius of wireless communication signals coverage) according to L, R numerical value and zoning ordinance, again in conjunction with above-mentioned zoning ordinance, this territory can be calculated fast and the center point coordinate value in all districts of covering.
It should be noted that, general district or the territory of dividing is all regular shape, for example: triangle, square, rectangle, regular hexagon etc., for describing with central point in the region of this regular shape, and try to achieve the occurrence of partition address.Especially, be difficult to divide ground irregular area by regular shape for some, can directly describe with multiple vertex coordinates of closed interval, and the mapping relations tables of data of default this area information and address, by these mapping relations data table stores in scalar/vector 103, can try to achieve by tabling look-up the occurrence of address, particularly, determine that according to locating information the current residing region of said apparatus is an irregular area, can be according to the coordinate information in this region in the mapping relations that prestore, directly in table, find source address and the destination address of this device.Be address above mentioned generation unit 103, can also, specifically for according to the mapping relations tables of data of above-mentioned partition information and prestore positional information and address, table look-up and obtain source address, clean culture destination address and the multicast destination address of said apparatus.
