[0074] For example, as a specific application, when the predetermined error range a plurality of standard memory and characteristic fingerprint to be the subject feature vector matching, WiFi MAC value according to the narrow range of floors, i.e., the above-described feature vector to be detected WiFi MAC values fingerprint database searched floor number corresponding to a range; narrow room number or public spaces namescope the signal strength values ​​WiFi, i.e. WiFi signal strength value detection feature to be vectors in a previous step standard characteristic fingerprint vector searched out of the room corresponding to a range , it may be a building or the entrance and the common peripheral boundary aisle; further narrow the base station parameters, like e.g. orientation, i.e. when the step is not unique search results are still obtained, in accordance with the parameters of the base station may be estimated in accordance with the orientation; the feature vector to be detected parameters match all items are still not uniquely determined after indoor location of the terminal to be positioned, these vectors can not be determined at various locations referred to as "possible set", to be detected is calculated feature vector "may be set" for each location within the vector similarity between, a "minimum distance vector method" to give a maximum similarity "can Can set "vectors, i.e.: acquiring object feature vector to be the smallest standard error of feature vectors, to be positioned so that estimated positional coordinates of the terminal chamber.

[0075] Since the positioning terminal needs to be known to be located indoors its position, can be positioned called party, the party initiating the positioning request, e.g., a mobile terminal device, service platform, called a locator side. Further, after positioning the platform to be positioned to obtain a positioning result or the terminal positioning result information, can send the location result to the positioning, or positioning result information requests a location, e.g., service platform or terminal to be positioned, the service platform may be further forwarding the positioning result or a positioning result information of the terminal to be positioned to a third party requests positioning of a terminal. Positioning terminal requests to be located, after acquiring periodically transmits signals to a multimode platform positioned at the location of the uplink message and receives a positioning result or a positioning result information returned from the positioning platform, specifically by the terminal to be positioned between the positioning platform heartbeat packets to exchange information. The actual service is often establish separate service platform, the service platform for the third party terminal in response to a request by a location platform initiative to obtain the indoor position of the mobile terminal to be, correspondingly, the terminal receives an instruction to be located positioning table, acquiring location multimode signals and uploaded to locate platform, indoor location positioning platform to obtain the coordinates of the terminal to be located in accordance with a certain algorithm, and back to the service platform, initiated by the service platform back to the third-party terminal location.
