Abstract

A position information distribution server includes: a communication unit that is provided outside a core network and receives identification information of a cellular phone and position information of the cellular phone from base transceiver stations, switching centers, VLRs, or an HLR; and a recording unit that records a first table including information to specify a server transmitting the position information among position information provision servers, for each identification information of the cellular phone. The position information provision servers are servers that provide position information services for transmitting the position information transmitted from the position information distribution server to information terminals. When the communication unit receives the identification information and the position information of the cellular phone, the communication unit transmits the identification information and the position information of the cellular phone to a server shown in the first table among the position information provision servers.
