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 communication system includes a first base station device, and a first wireless terminal device, the first base station device acquires identification information of a plurality of base station devices including the first base station device, acquires communication load of each of the plurality of base station devices, transmits the communication load and the identification information of each of the plurality of base station devices to the first wireless terminal device, and changes a serving base station device of the first wireless terminal device to a second base station device and which the first base station device is notified of by the first wireless terminal device, and the first wireless terminal device notifies the first base station device of the identification information of the second base station device selected based on the communication load from the plurality of base station devices.

Wireless communication system and wireless communication method

A radio access system includes a controlling apparatus that when the terminal apparatuses to which delivery data is to be delivered are concentrated in a particular area, groups the terminal apparatuses as a terminal apparatus group, selects a representative server terminal apparatus from the terminal apparatuses, creates data map information indicating a delivery rule for delivering the delivery data from the representative server terminal apparatus to another terminal apparatus, adds information for identification of the representative server terminal apparatus to the data map information, transmits the group information and the data map information to the terminal apparatuses, and instructs a delivery data server to deliver the delivery data to the representative server terminal apparatus; and a terminal apparatus that obtains the delivery data by communicating, in accordance with the received data map information, with the another terminal apparatus within the terminal apparatus group included in the received group information.

Radio access system, controlling apparatus, and terminal apparatus

The present invention provides a mobile phone system, which can give a desired voice message to a user of an opposite party terminal without speaking in a state that limitation to usable voice messages has been reduced, while allowing a user existing under an environment that he/she can not speak to listen to a voice from the opposite party terminal. A mobile phone terminalis provided with meansfor transmitting a connection request of a packet switching line to the side of a network and meansfor transmitting data corresponding to a desired voice message, while the network is provided with data/voice message converting meansfor converting transmitted data to a voice message corresponding thereto and means for merging the converted voice message to a circuit switching line of the opposite party terminal to transmit the same.
