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.

Abstract: Disclosed is a technique to enable a session handover between devices with different key generation functions in an authentication protocol. According to the technique, when a session where a UE (200) receives contents from a contents server (700) is to be handed over to a target node (300), the UE firstly transfers information (session HO information) necessary to the session handover to the target node (Step S1001). The target node performs authentication processing with an authentication server (600) of the network to which the UE is connected and notifies the authentication server of the session HO information transferred from the UE (Step S1003). The authentication server performs authentication for the session handover based on the session HO information, and when the authentication succeeds, the session is handed over from the contents server to the target node, and the contents are distributed to the target node (Step S1005).
