The WiFi hotspot automatic search system operates in 3 (the communication device 1) the 3G communication device 1 further includes a memory η 'processor 12 and a positioning device 13. The memory 11 stores a WiFi hotspot The location correspondence table 110 is configured to store information such as the location of the wiFi hotspot used by the 3G communication device 1. The positioning device 13 may be a GPS (

Globe Positioning System: Global Positioning System). [0009] Referring to Figure 2, there is shown a schematic diagram of a wiFi hotspot location correspondence table in a preferred embodiment of the present invention. The WiFi hotspot location correspondence table 11A shows the latitude and longitude information corresponding to the plurality of WiFi hotspots used by the 3G communication device. For example, (XI 'Y1) indicates the position of the location where the W i F i hot spot is located, . : , :: Degree is XI, and the latitude is Yl ; (X2, Y2) indicates that the longitude of the location of the WiFi hotspot 2 is X2, latitude Is Y2. [0010] The WiFi hotspot automatic search system 10 may be installed in the memory 11: . . . . . ':. . . , the processor 12 controls the execution of the WiFi hotspot automatic search system 10. Row. The WiFi hotspot automatic search system 10 includes a recording module 101, a read: . . . "" module 102 and a determination module 103. The functional modules described above are described in detail below with reference to FIG. 4. [0011] As shown in FIG. 4, it is a flowchart of a preferred embodiment of the WiFi hotspot automatic search method of the present invention. [0012] Step S02, the recording module 101 configures the WiFi hotspot location correspondence table 110. Specifically, The method for configuring the WiFi hotspot location correspondence table 110 is as follows: First, when the 3G communication device 1 manually or automatically starts the WiFi hotspot search function and successfully searches for the w iF丨 hotspot, the recording module 1 01 099112758 form number A0101 6 page / Π page 0992022573-0 201138510 triggers the positioning device 13 to locate the position of the 3G communication device 1 to obtain the latitude and longitude of the location of the 3G communication device 1; then, the recording module 101 will position the device 13 The acquired latitude and longitude is recorded in the HFi hotspot location correspondence table 110 as the latitude and longitude of the location of the searched WiFi hotspot, and the configuration of the WiFi hotspot location correspondence table 11 is completed. Since the effective range of the WiFi hotspot is generally in a small light-light area centered on the wiFi hotspot and having a radius of not more than 30 m, the latitude and longitude of the current position of the 3G communication device 1 is recorded as the searched The latitude and longitude of the location of the W i F i hot spot has a small error. 〇[0013] The configured W i F i hotspot location correspondence table 11 can be used for the 3 G communication device to switch to the W i F i network later. The above step S02 can be performed when the 3G communication is not ready at any time, successfully searched for a new WiFi hotspot. [0014] Step S03, when the 3G communication device 1 is not connected to the wiFi During the network, the reading module 102 reads the 3G from the communication signaling between the 3G network communication base station (shown as 30 in FIG. 3) and the 3G communication device 1 at regular intervals. The latitude and longitude of the current location of the communication device 1 (such as the latitude and longitude information contained in the paging signaling). Currently, most wireless network base stations provide location services, especially WCDMA, CDMA2000 and TD-SCDMA based on CDMA technology. Waiting for the 3G communication network base station Positioning service: The 3G network communication base station can locate the 3G communication device by means of 〇td〇a (〇b aserved Time Difference 〇f Arrival: observe the time difference of arrival) 〇TI)〇A positioning The method is to calculate the position of the 3G communication device by observing the time difference of the signal sent by the plurality of base stations (the communication device 1), the 099112758 form number A0101 page 7 / 17 pages 0992022573-0 201138510 0TD0A positioning mode positioning accuracy can be up to tens of meters, there is a certain error 'but the position of the 3G communication device 1 can be roughly positioned. Here, if the positioning device 13 is used to accurately locate the position of the 3G communication device 1 'it will waste a lot of power because of the long-term operation of the positioning device 13', so the positioning service of the 3G network communication base station is taken first. The location of the 3G communication device 1 is roughly located, and when the location of the 3G communication device 1 is close to a certain distance of the WiFi hotspot in the WiFi hotspot location correspondence table 11〇, such as l〇〇m, start again. The positioning device 13 precisely positions the position of the 3G communication device 1. [0015] Step S04, the determining module 103 determines, according to the latitude and longitude information read by the reading module 102, whether the 3G communication setting 1 is currently in an arbitrary position in the WiFi hotspot location correspondence table 110. A WiFi hotspot is centered, and the first predetermined distance is the first radiation area of the radiation radius (as shown in FIG. 3). If the 3G communication device 1 is located in the first radiation area, the positioning is triggered. The device 13 performs step S05, otherwise 'returns to step S03. The first preset distance may be set according to the positioning accuracy of the 3G network communication base station of the disc. For example, if the positioning precision of the 3G network communication base station adopts the 0TD0A positioning mode is several tens of meters, the first setting may be set. The preset distance is 100m. [0016] Step S05, the positioning device locates the 3G communication device 1 in real time to obtain the latitude and longitude of the current position of the 3G communication device 1. [0017] 099112758. In step S06, the determining module 103 determines, according to the latitude and longitude of the current location of the 3G communication device 1 acquired by the positioning device 13, whether the 3G communication device 1 is currently in the WiFi hotspot location correspondence table 110. Any one of the WiFi hotspots is centered, the second form number with the second preset distance as the radius of radiation A0101 Page 8 / Total 17 pages 0992022573-0 201138510 [0018] [0019] [0020] [0021] ❹ [0022 In the radiant area (shown as 34 in FIG. 3), if the 3G communication device 1 is in the second radiant area, the 3G communication device 1 is triggered to perform step S09, otherwise step S07 is performed. The second preset distance may be set according to an effective radiation range of the WiFi hotspot. For example, when the effective radiation range of the WiFi hotspot is 30 m, the second preset distance may be set to be 30 m or 40 m. In step S07, the determining module 103 determines whether the 3G communication device 1 is still in the first radiation area according to the latitude and longitude of the current position of the 3G communication device 1 acquired by the positioning device 13, if the 3G communication device 1 is still in the first radiation area, then returns to step S05, otherwise, the 3G communication device 1 is triggered to perform step S08. Step S08, the 3G communication device 1 closes the positioning device 13, and ends the process. Step S09, the 3G communication device 1 starts the WiFi hotspot search function to search for the WiFi hotspot. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
