The invention provides a method and a device of obtaining geographical location information of a wireless access device. According to preset corresponding relations of identification information of access points of wireless fidelity (Wi-Fi) and first geographical location information, first geographical location information corresponding to identification information of each Wi-Fi access point is obtained, wherein the first geographical location information is included in location request information; and accordingly, according to the first geographical location information corresponding to the identification information of the each Wi-Fi access point and the identification information of the wireless access device, second geographical location information corresponding to the identification information of the wireless access device is obtained, wherein the identification information of the wireless access device is included in the location request information. The problem that in the prior art, because a locating platform can not obtain the geographical location information of the wireless access device, the locating platform can not provide location service to terminals is avoided, and therefore reliability of obtaining the geographical location information of the wireless access device is improved.
Description
【Technical field】 [0001] The present invention relates to communication technology, in particular to a method and device for acquiring geographical location information of wireless access equipment. 【Background technique】 [0002] In a mobile communication network such as a Wideband Code Division Multiple Access (WCDMA) network, the positioning platform can provide positioning services to the terminal by obtaining geographic location information of a wireless access device, such as a base station (NodeB). [0003] For example, the positioning platform may receive the geographic location information of the base station sent by the network management system of the mobile communication network, wherein the geographic location information of the base station is obtained by the base station using a Global Positioning System (Global Positioning System, GPS) and sent to the network management system. system. [0004] Or, for another example, the positioning platform may receive th...
