Abstract: According to the present invention, when receiving a connection request including an SIM-ID from a terminal 20, a connection node 16 connects the terminal to a connection destination APN which is associated with the SIM-ID. A user management server 10 and an SIM-ID management server change the connection destination APN associated with the SIM-ID according to a change in a use state of a prepaid SIM, and distributes, to the connection node 16, an association relationship between the SIM-ID and the connection destination APN. By this process, the connection destination APN of a terminal connected to a network can be automatically switched according to a change in an identifier use state of the prepaid SIM.

Abstract: A location support relating to a mobile station that can make use of multiple communication networks more efficiently. In an SUPL server of a location system, a judgment is made as to which of two communication networks is accessed by a mobile station based on information specifying the access point of the mobile station, with this access point being notified from the mobile station, whereby the information is then notified from the SUPL server to a location information management device. As a result, in the location information management device, requests to a communication network, which is not accessed by the mobile station, for location information for use in location of the mobile station are suppressed. This makes it possible for location support relating to a mobile station capable of using multiple communication networks to be carried out more efficiently.

Abstract: Provided is a positioning support device that provides approximate location information including more appropriate error radius information. With a positioning method (positioning support method) by a positioning support system 10 and a positioning system 1 including the positioning support system 10, it is determined in a SUPL server 20 whether an error radius included in location information (approximate location information) of a base station device 70 acquired from a mobile communication network N2 that is another communication network falls within a prescribed range. If out of the prescribed range, the error radius is updated to a predetermined value, and approximate location information including the updated error radius information is thereafter transmitted to a mobile station 60 for positioning computation. This makes it possible to provide approximate location information including more appropriate error radius information for positioning computation.

Abstract: A mobile communications service control apparatus comprises signal processing means for conducting prescribed signal processing of a packet transmitted from a mobile terminal or preset communications-equipment, information restoring means for restoring information of a layer higher than a transmitted layer of the signal-processed packet, and service providing means for providing a service in accordance with the contents of the restored information.
