摘要： The communication terminal apparatus measures reception quality and reports the measurement result to the base station apparatus, and the base station apparatus switches the transmission rate based on the reported result of the reception quality. In this way, the transmission rate is switched starting at the point in time at which the reception quality of the communication terminal apparatus deteriorates. Furthermore, the transmission rate is switched so that the amount of interference with others is within the allowable range according to the channel condition between the communication terminal apparatus and base station apparatus.

摘要： Signals subjected to orthogonal modulation with a plurality of carrier frequencies are added to detect peak power. Based on the peak power, a coefficient for suppressing an amplitude of a transmission baseband signal is calculated. Using the coefficient, the amplitude of a baseband signal to be inputted to a filter is suppressed. It is thereby possible to suppress the peak power assuredly, and by the effects of the filter, unnecessary frequencies are not generated.

摘要： Provided are white space sharing control method, database device, agent device and communication system with which use of white space (WS) is controlled when a plurality of WS wireless devices compete for use of WS. In ST105, an application A proxy device arbitrates WS channel use requests received from a plurality of application A first WS wireless devices and combines these requests into one, and, in ST107, the application A proxy device transmits the arbitrated WS channel use request and location information to a frequency database apparatus. In ST108, the frequency database apparatus decides whether or not application A and application B are available on the basis of the “arbitrated WS channel use request and location information” and “priority ranking information according to use”. In ST109, the frequency database apparatus updates application A database information and application B database information on the basis of the decision result.

摘要： A wireless terminal transmits a result of measuring received power of a downlink wireless signal from a femtocell base station to a macrocell base station. The macrocell base station transmits an interference control request including identification information of the wireless terminal to a femtocell base station group of which received power of a downlink signal included in a measurement result transmitted from the wireless terminal is a predetermined value or more. The femtocell base station has an adjacent wireless terminal list in which identification information of a wireless terminal, which is capable of being connected to an adjacent femtocell base station but is not capable of being connected to the femtocell base station, is recorded, and downlink transmission power of the femtocell base station is reduced when the identification information included in the interference control request is included in this list.

摘要： By introducing a hierarchical encryption scheme and the use of asymmetric cryptography, the critical information in message exchanges is concealed from unauthorized entities. This helps greatly in preventing man-in-the-middle attacks faced by inter-working. In addition, access control is conducted by introducing a network structure having a rule interpreter that is capable of mapping general rules to WLAN specific commands. It obviates the needs for mobile user's home network to understand information about every WLAN it is inter-worked with. A common interface independent of WLAN technologies could be used by the home network for all the WLANs. The above conception provides a solution to the problems of the protection of user identification information and access control in the inter-working of WLAN.

摘要： An access control method for a plurality of data communications networks is disclosed that enables a plurality of local nodes (101) to communicate with each other even if the connection between an intermediate node (103) and a global server (105) is momentarily lost. In this method, when the connection to the global server (105) breaks down, the intermediate node (103) temporarily grants access to the local nodes (101) instead of the global server (105) in accordance with a predetermined policy, thus allowing operation of local networks to function normally until connection to the global network (104) is resumed.

摘要： A mobile network control apparatus capable of improving transmission efficiency without giving any processing loads to nodes of a mobile network. In mobile routers 121, 131, 132 to which the present apparatus is applied, a tunnel failure detection unit 204 detects a failure of packet tunneling executed using an interface 205-1 of the mobile routers 121, 131, 132. A multi-homing detection unit 202 searches for interfaces 205-A, 205-B having a connection route to a global network 101 out of an interface 205 of the mobile routers 121, 131, 132 according to the detected failure of packet tunneling. A bidirectional tunneling unit 203 executes packet tunneling using the searched interfaces 205-A, 205-B instead of the interface 205-1.

摘要： An assignment section 101 determines communication resource assignment to communication terminals based on a transmission rate at which communication is possible for each subcarrier of each communication terminal, and instructs a buffer section 102 to output forward transmission data. In addition, the assignment section 101 instructs a frame creation section 103 to perform forward transmission data symbolization, and also outputs a signal indicating communication resource assignment to each communication terminal. The buffer section 102 holds forward transmission data, and outputs forward transmission data to the frame creation section 103 in accordance with instructions from the assignment section 101. The frame creation section 103 symbolizes a resource assignment signal and transmission data to create a frame, which it outputs to a spreading section 104.
