Abstract:

A positioning method and apparatus. The method comprises: setting a fuzziness adjustment parameter for a mobile device, the fuzziness adjustment parameter being used for recording fuzziness changes used by the mobile device to determine virtual station observation values (S110); adjusting an observation value of a first primary reference station according to a first fuzziness adjustment parameter value of the mobile device in a first serving cell to generate a first virtual station observation value, the first primary reference station being a primary reference station of the first serving cell, and the first virtual station observation value being used for positioning the mobile device in the first serving cell (S120); and sending the first virtual station observation value to the mobile device (S130). By setting a fuzziness adjustment parameter for a mobile device, and adjusting, according to fuzziness adjustment parameter values of the mobile device in different cells, observation values of primary reference stations of the different cells, the positioning method and apparatus can ensure the continuity of a positioning service.
