Abstract: There is provided a communication control method of a first terminal device for causing the first terminal device and a second terminal device positioned in the proximity of the first terminal device to establish a direct communication path. The communication control method includes: a step of monitoring a signal which is transmitted from the second terminal device so as to allow a proximity terminal device to discover the second terminal device; a step of receiving the signal to detect that the second terminal device is positioned in proximity; a step of acquiring coverage information which is included in the signal and indicates whether or not the second terminal device is served in a LTE base station; and a step of detecting whether or not the second terminal device is served based on the coverage information.

Abstract: UE receives a mobile operator policy including flow identification information, access system identification information, and a degree of compulsion from an ANDSF, and in a case where the degree of compulsion included in the mobile operator policy is a degree of compulsion that compels the UE to perform switching, transmits a request to forcibly switch a communication path used flow communication corresponding to the flow identification information to an access system corresponding to the access system identification information included in the mobile operator policy. As a result, by transmitting an MO policy from the ANDSF to the UE while the UE connected to a first access system is performing data communication, the UE changes a UE policy to the MO policy, thereby providing a mobile communication system or the like that is capable of avoiding concentration of traffic in the first access system.

Abstract: When a UE (User Equipment) that performs data transmission/reception in a neighborhood service detects a neighboring terminal, the UE receives a piece of information on a search range before neighborhood search of a UE as a communication target and searches for the UE as the communication target on the basis of the piece of information on the search range. This allows a mobile telecommunications carrier to control the search range.

Abstract: A displacement detecting apparatus is provided with a self-position detector for detecting a position and an orientation of the apparatus relative to a preset reference position and a preset reference orientation. Displacement of a rail at an upper surface reference point and a side surface reference point relative to a preset reference position is calculated from imaged image data of the surfaces of the rail using an optical cutting method, and the calculated displacement of the rail is corrected using data obtained from the self-position detector, thereby compensating for errors caused by differences in position and orientation of the apparatus associated with a vehicle running motion. By doing so, the displacement detecting apparatus is superior in maintenance and unlikely to cause measurement errors.

Abstract: A policy management device transmits an update of a mobile operator policy that requests to switch an access system for each flow that UE is going to perform communication. In addition, the policy management device requests to enable a network interface that is to be used for performing communication by making a connection to the switched access system. The UE compares the received update of the mobile operator policy with a UE policy that is held in advance and determines which is to be preferentially used. In a case where the UE determines to preferentially use the mobile operator policy, the UE switches the access system to offload communication.
