Positioning server device and positioning control method
First Claim
1. A positioning server apparatus comprising:
- an input section that inputs measurement information of a radio wave transmitted between an access point and a client;
a radio wave map managing section that manages radio wave map data representing a correspondence relation between the measurement information and a spatial location; and
a positioning section that measures a location of the client based on the measurement information and the radio wave map data, wherein the radio wave map managing section manages first map data and second map data as the radio wave map data, the first map data related to a fixed positioning range where there is a possibility that the client to be positioned is present during normal operation, and the second map data related to an extended positioning range where there is possibility that the client to be positioned is present under a specific condition.

Abstract
A positioning server device comprises: an input unit which receives measurement information of radio waves which are transmitted between an access point and a client; a radio wave map administration unit (10) which administers radio wave map data which denotes an estimation of a correspondence relation between the radio wave measurement information and a spatial location; and a positioning unit (13) which positions the location of the client based on the radio wave measurement information and the radio wave map data. The radio wave map administration unit (10) administers first map data which relates to a fixed positioning range where it is possible for a client to be positioned to be present conventionally, and second map data which relates to an extended positioning range wherein a possibility arises that the client to be positioned may be present according to particular conditions, as radio wave map data.

9. A positioning control method comprising:
-
inputting measurement information of a radio wave transmitted between an access point and a client; measuring a location of the client based on the measurement information and radio wave map data representing a correspondence relation between the measurement information and a spatial location; and updating the radio wave map data based on the measurement information and a positioning result of the client, wherein the radio wave map data includes first map data related to a fixed positioning range where there is a possibility that the client to be positioned is present during normal operation and second map data related to an extended positioning range where there is possibility that the client to be positioned is present under a specific condition. - View Dependent Claims (10)
