Patent ID: 8825393

Claim:
A location service providing method for providing a location of a mobile terminal, wherein the method is performed by one or more servers the method comprising: determining a positioning method based on location information of the mobile terminal and measurement information used for calculating the location of the mobile terminal; determining a map switch indicator by using at least one of the determined positioning method, the location information, and the measurement information; selecting a global map or a local map according to the determined map switch indicator; and indicating the location of the mobile terminal on the selected map, wherein the location information coin rises location information of the mobile terminal provided currently and provided in the past navigation satellite system (GNSS), and the measurement information comprises the number of transmitters of the wireless communication infrastructure capable of wirelessly communicating with the mobile terminal, the number of visible satellites of the GNSS, a carrier-to-noise ratio (CNo) or a signal-to-noise ratio (SNR) of the respective GNSS visible satellites, and a dilution of precision (DoP) of the location information, wherein, in determining the positioning method, when there are transmitters in the wireless communication infrastructure, there are visible satellites, and the sum of the number of the transmitters of the wireless communication infrastructure and the number of the visible satellites is equal to or greater than a reference number, positioning by compositing measurement information provided from the GNSS and measurement information provided from the wireless communication infrastructure is determined as the positioning method, wherein, in determining the positioning method, when there are transmitters in the wireless communication infrastructure, there are visible satellites, and the sum of the number of the transmitters of the wireless communication infrastructure and the number of the visible satellites is smaller than the reference number, positioning based on the wireless communication infrastructure is determined as the positioning method, wherein the ma switch indicator is an internal value used to select the global map or the local map to indicate the location of the mobile terminal.
