Positioning method and device

A smart device, comprising:

• a processor, and
• a memory for storing instructions executable by the processor,
• wherein the processor is configured to perform:
• collecting and analyzing wireless messages sent by at least one wireless device in a current space to obtain a first characteristic pattern associated with the current space;
• performing a matching process to match the first characteristic pattern to at least one of a plurality of preset characteristic patterns, each of the plurality of preset characteristic patterns being associated with one of a plurality of spaces;
• obtaining, if the preset characteristic patterns comprise a second characteristic pattern that matches the first characteristic pattern, space information corresponding to the second characteristic pattern;
• and
• determining a position of the current space by using the space information corresponding to the second characteristic pattern,
• wherein each characteristic pattern comprises a correspondence between an identifier of each wireless device in a corresponding space and a signal quality of the wireless device;
• and
• wherein performing the matching process to match the first characteristic pattern to at least one of the plurality of preset characteristic patterns comprises:
• comparing each of the plurality of preset characteristic patterns with the first characteristic pattern;
• and
• determining that the second characteristic pattern associated with a second space matches the first characteristic pattern, if the second characteristic pattern comprises identifiers of all the wireless devices in the current space and signal quality of the wireless devices in the first characteristic pattern is similar to that of wireless devices in the second characteristic pattern.

A non-transitory computer-readable storage medium storing instructions, executable by a processor in a smart device, for performing a positioning method, the method comprising:

• collecting and analyzing wireless messages sent by at least one wireless device in a current space to obtain a first characteristic pattern associated with the current space;
• performing a matching process to match the first characteristic pattern to at least one of a plurality of preset characteristic patterns, each of the plurality of preset characteristic patterns being associated with one of a plurality of spaces;
• obtaining, if the preset characteristic patterns comprise a second characteristic pattern that matches the first characteristic pattern, space information corresponding to the second characteristic pattern;
• and
• determining a position of the current space by using the space information corresponding to the second characteristic pattern,
• wherein each characteristic pattern comprises a correspondence between an identifier of each wireless device in a corresponding space and a signal quality of the wireless device;
• and
• wherein performing the matching process to match the first characteristic pattern to at least one of the plurality of preset characteristic patterns comprises:
• comparing each of the plurality of preset characteristic patterns with the first characteristic pattern;
• and
• determining that the second characteristic pattern associated with a second space matches the first characteristic pattern, if the second characteristic pattern comprises identifiers of all the wireless devices in the current space and signal quality of the wireless devices in the first characteristic pattern is similar to that of wireless devices in the second characteristic pattern.
