Cognitive radio is an emerging technology to further improve the efficiency of spectrum use. Due to the nature of the technology, it has many facets, including its enabling technologies, its implementation issues and its regulatory implications. In ITU-R (International Telecommunications Union\-Radiocommunication sector), cognitive radio systems are currently being studied so that ITU-R can have a clear picture on this new technology and its potential regulatory implications, from a viewpoint of global spectrum management. This paper introduces the recent results of the ITU-R studies on cognitive radio on both regulatory and technical aspects. This paper represents a personal opinion of the author, but not an official view of the ITU-R. © 2012 The Institute of Electronics, Information and Communication Engineers.


It is left to a communication terminal side to judge whether to switch communication, and appropriate switching is not performed if a communication terminal does not have a function to switch communication based on the quality of communication. A communication apparatus comprises: a data signal transmitting unit that transmits a data signal to a communication terminal; a control signal transmitting unit that transmits a control signal for establishing communication with the communication terminal; and an area control unit that restricts, to a partial area within a communication possible area that a radio wave including the data signal can reach, a communication establishment possible area that a radio wave including the control signal can reach.

A satellite communication system may be configured to establish multiple different tunnels between a first satellite modem and a second satellite modem in accordance with a protocol. The first satellite modem may receive a packet via a tunnel established in accordance with a different protocol, determine an endpoint identifier corresponding to the tunnel based on information from one or more headers included in the packet, identify one of the multiple different tunnels that corresponds to the tunnel, generate a corresponding packet omitting at least a portion of the information from the one or more headers and comprising at least a portion of data included in a payload of the packet and an information block comprising a tunnel index corresponding to the identified one of the multiple different tunnels, and transmit the corresponding packet to the second satellite modem via the identified one of the multiple different tunnels.

A wireless communication processing decision unit 33 acquires, from a wireless communication specific information storage unit 52, wireless communication specific information which specifies regions in which utilization of its frequency bandwidth is permitted by law. Next, registered position information which specifies the region in which this mobile communication terminal is position registered is acquired from a registered position information storage unit 34. Next, if the region specified by the registered position information is included in the regions shown by the wireless communication specific information, then the wireless communication processing decision unit 33 makes a decision to the effect that communication is possible, and notifies a communication processing unit 53 of this permission of communication. Upon receipt of this communication permission, the communication processing unit 53 starts communication processing.

The terminal according to the present application has a connection unit that connects to an access point for a communication network The terminal also has a connection control unit that scans a network registered in a connection list, subtracts access points registered in a exclusion list from the detected access points to identify access points to which connection is possible, initializes the exclusion list if an access point to which connection is possible is not identified and then again identifies an access point to which connection is possible, and selects an access point to connect to, out of identified access points to which connection in possible. The terminal further has a connection ending unit that, if the start of a connection to an access point registered in a duplicate exclusion list is detected, cuts the connection with the access point, and also deletes the corresponding network from the connection list.
