[0046]步骤301:获取基站的GPS信息、基站天线的方向角和基站覆盖的小区的标识信息; 并获取WIFI热点的GPS信息; [0046] Step 301: the base station acquires GPS information, the identification information of the base station antenna directional angle and the cell base cover; and acquires GPS information WIFI hotspot;

[0047]步骤3〇2:根据基站的GPS信息以及基站天线的方向角计算出该基站覆盖的所有小区的GPS和各小区的覆盖范围; [0047] Step 3〇2: calculated GPS coverage and each cell to all cells covered by the base station based on the direction information and the GPS base station antenna angle;

[0049]其中,根据基站的GPS信息和基站天线的方向角计算出该基站覆盖的所有小区的覆盖范围包括: [0049] wherein, calculated from GPS information and the direction angle of an antenna base station coverage of all cells covered by the base station comprising:

[0050]将基站覆盖的所有小区按照各小区天线方向角进行排序得到小区队列; [0050] All cells according to each cell covered by the base station antenna angle obtained cell sorting queue;

[0051] 将该队列中后一个小区的天线方向角减去前一个小区的天线方向角的差值除以二得到的值,作为前一个小区的右覆盖角和后一个小区的左覆盖角; [0051] The difference between the antenna before a cell minus the angle of the queue a cell antenna angle obtained by dividing the value of the two, as a cell of the right front corner and the rear left covering a cell coverage angle;

[0053]取各小区左覆盖角和右覆盖角中较大的作为各小区的覆盖角a; [0053] Each cell taken left and right angle coverage covers a larger angle as the respective cell coverage angle a;

[OO54]根据各小区的GPS信息计算得到各小区的覆盖半径R,上述过程具体可由通信终端完成,也可由第三方终端(例如PC机)完成,具体如下: [OO54] GPS information calculated for each cell obtained in each cell coverage radius R according to the specific process is completed by the communication terminal, the terminal may also be a third party (e.g., a PC) is completed, as follows:

[0055] 每个小区周围有六个小区(对应天线中心激励)或4个小区(对应天线顶点激励), 分别计算各小区与其周围各小区的距离D,从计算得到的各距离D中选择最大一个D除以3为小区的半径R。 [0055] There are six cells around each cell (corresponding to the center of the antenna excitation) or 4 cells (corresponding to the excitation antenna apex) were calculated for each cell and its surrounding cells each distance D, the distances D from the calculated maximum selected 3 D by a cell radius R.

[0056] 应该理解的是,此处计算R和a的各步骤之间没有严格的时序限制。 [0056] It should be understood that there is no strict timing constraints between steps where R and a are calculated.

[0057]进一步的,根据各WIFI热点的GPS信息得到各WIFI热点与各小区的对应关系包括: [0058] 计算WIFI热点与各小区之间的距离d,并计算各WIFI热点与各小区方向角的夹角0,此处计算P的过程具体如下:通过WIFI热点的GPS坐标与小区所在基站的GPS坐标,两个点构成矢量,计算该矢量的矢量角,矢量角与小区方向角的差的绝对值,为P。 [0057] Further, to obtain the relationship between each WIFI hotspots with the GPS information of each cell WIFI hotspots comprising: [0058] calculation of the distance d between the respective cell WIFI hotspots, WIFI hotspots and calculate the direction of each corner cell angle 0, the process P is calculated here as follows: GPS coordinates by GPS coordinates of the base station of the cell where WIFI hotspots, two dots vectors, calculates the vector angle of the vector, and the vector angle difference between the angle of the direction of cell absolute value for P. 应该理解的是, 此处计算d和P的各步骤之间也没有严格的时序限制。 It should be appreciated that the various steps of calculating P between d and here there is no strict timing constraints. 然后根据各WFI热点与各小区之间的距离d、各WIFI热点与各小区方向角的夹角0以及各小区的覆盖角a和覆盖半径R判断各WIFI 热点分别落入哪些小区内,例如:若某个WIFI热点的0小于某个小区的《,且该WIFI热点的d 小于该小区的R,则该WIFI热点在该小区中;然后将覆盖有WIFI热点小区的标识信息存入WIFI热点小区列表中。 Then based on the distance d between the hot WFI each cell, each of WIFI hotspots angle 0 direction angle of each cell and each cell of a coverage angle and the coverage radius R is determined to fall within the respective WIFI hotspots which cells are, for example: If a 0 is less than a WIFI hotspot cell, "and the WIFI hotspot R d is smaller than the cell, the WIFI hot spot in the cell; and then covered with a WIFI hotspot identifier information stored in the cell-cell WIFI hotspots List.
