A positional information managing device includes a processor. The processor is configured to manage first positional information of a first mobile device communicating with a network. The processor is configured to associate device information of a second mobile device connected to the first mobile device with the first positional information. The second mobile device communicates with the network through the first mobile device.

Positional information managing device, mobile terminal, and mobile device

A communication system including: a terminal, and a base station configured to wirelessly couple to the terminal using a first frequency band, wherein a second frequency band is used for wirelessly coupling the base station to the terminal instead of the first frequency band only when a specified application program executed in the terminal communicates only with a specified network via the base station, the second frequency band being used for communication between the specified application program and the specified application program.

Communication system, base station, and terminal

A wireless access system includes a terminal; and a fixed terminal control apparatus configured to identify based on position information of the terminal, whether the terminal is a fixed terminal having no change in position for a predetermined period of time, the fixed terminal control apparatus identifying whether the terminal is the fixed terminal, when the fixed terminal control apparatus receives from the terminal, a connection request requesting connection to a network of the terminal, the fixed terminal control apparatus further configured to deny the connection request according to a predetermined probability, when identifying the terminal to be the fixed terminal.

Wireless access system and fixed terminal control apparatus

A wireless access system includes: a first communication system that performs communications by a first communication scheme; a second communication system that performs communications by a second communication scheme different from the first communication scheme; and a communication terminal capable of communicating with both the first communication system and the second communication system. A base station of the first communication system transmits, to the communication terminal, a threshold value in accordance with an elapsed time is measured from a first point in time at which the communication terminal previously enters a second communication area that is an area of the second communication system to a second point in time at which the communication terminal previously exits from the second communication area to a first communication area that is an area of the first communication system.

Wireless access system, base station, and communication terminal

A base station includes a receiving unit, a determining unit, a control unit, and a transmitting unit. The receiving unit receives a connection request signal when the base station is in a power-saving state. The determining unit, when the receiving unit receives the connection request signal, determines whether a priority of the base station is higher than a priority of a different base station that belongs to a same group as the base station. The control unit, when the determining unit determines that the priority of the base station is higher than the priority of the different base station, causes the base station to return from the power-saving state to a normal state. The transmitting unit wirelessly transmits a notification signal after the base station is returned to the normal state by the control unit.

Base station

A mobile station that includes a mobile station controller which performs a process of responding to a call signal and a wireless base station that includes a base station controller which performs a determination of a priority of the call signal to be transmitted to the mobile station and a baseband unit that transmits a first call signal having a first priority to the mobile station and that stores a second call signal having a second priority in a queue and performs a transmission process wherein when the second call signal has been discarded, the baseband unit notifies the mobile station of information representing that the second call signal has been discarded and the mobile station controller executes, when deciding the second call signal has been discarded, a processing of an inquiry response to the wireless base station.

Wireless communication system, wireless base station, mobile station, and wireless communication method

A base station includes at least one first application section, a determining section, and a controlling section. Each of the first application sections executes one of a plurality of first application programs corresponding to one of a plurality of first application services utilizing a first wireless communication service provided by a mobile virtual network operator. The determining section receives a connection request to connect to the first application service from a first terminal for using the first wireless communication service, and determines the first application section corresponding to the first application service specified in the connection request. The controlling section controls communications between the determined first application section and a server managed by the mobile virtual network operator and between the determined first application section and the first terminal.

Base station, wireless communication system, and wireless communication method

A wireless communication system, includes: a first base station; a second base station; a first terminal which transmits call connection data to the first base station; a second terminal which receives a call connection request; and a management device which manages location and movement of the first terminal, wherein the first base station employs a handover procedure to notify the management device, when receiving the call connection data from the first terminal, that a call connection destination of the second terminal which has received the call connection request is changed, and notifies the first terminal about a frequency of the second base station, and the first terminal transmits call connection data to the second base station based on the notified frequency.

Wireless communication system, base station, and wireless communication method

It administers a plurality of wireless base stations grouped into a plurality of groups, and performs the processing about the management, control and maintenance of the wireless base stations selectively for each of the groups. This enables the efficient management, control and maintenance processing of the wireless base stations.
