Abstract: In a case where reception power in a radio access point is high by external noise, the normalcy of the radio access point is tested. In order to judge the normalcy of the radio characteristic of the radio access point, a test is performed through the calling connection between a testing access terminal in the radio access point and a predetermined device. An RSSI is measured before and after the transmission of a test signal. When the RSSI exceeds a threshold value, the path loss of a reverse link connected from the radio access point to the testing access terminal is increased by an attenuator. Then, reception power in the testing access terminal decreases. Thus, initial transmission power in accordance with the reception power from the testing access terminal is raised and the calling connection of the testing access terminal can be performed even under the external noise.

Abstract: A maintenance and administration device of a wireless communication system having for an object to enable the acquisition of accurate location information, even with respect to mobile handsets in the Idle state, sets a mobile handset subscriber identifier and a paging flag to be valid and transmits a visited cell information acquisition request with respect to a call processing control device. In the case where the paging flag is set to be valid, the call processing control device transmits a paging message to the mobile handset, with the mobile handset in the Idle state, and makes it return a reply message. The call processing control device reports, to the maintenance and administration device, the cell having progressively transmitted the paging message reply message as mobile handset visited cell information.

Abstract: The present invention provides a wireless communication system and a terminal. A base station notifies terminals of an intensity of a received interference power. The terminal controls a transmission power for transmitting data to the base station, which is one of base stations and to which data is to be transmitted, by referencing an intensity of interference power (OSI) notified from base stations to which data is not to be transmitted. The terminal calculates a decision value for increasing/decreasing the transmission power, wherein the decision value is variable according to the current transmission power of the terminal and propagation attenuations between the terminal and the base stations to which data is not to be transmitted, and variably controls the amount of transmission power increase/decrease according to the decision value for increasing/decreasing a transmission power.

Abstract: A decryption key for decrypting data from an access node is distributed to an access terminal intending to receive the data. An authentication unit receives a message for terminal authentication including a terminal identifier from the terminal and authenticates the terminal. The authentication unit refers to a content registration table having stored in advance the content type of a content which the terminal can receive, in association with the terminal identifier, according to the received terminal identifier to obtain a corresponding content type. The authentication unit refers to a decryption data base having stored in advance a decryption key and its valid period in association with a content type, according to the obtained content type to obtain a corresponding decryption key and valid period. The authentication unit sends an authentication result and the decryption key and valid period to the terminal or to a packet control unit.

Abstract: A call processing control apparatus automatically detects that a lot of handover and location registration simultaneously occur, and notifies a monitor control server. The monitor control server receiving the notification from the call processing control apparatus transmits a TAI change request to a base station so that a tracking area identity (TAI) of a movement destination cell where congestion occurs and a tracking area identity of a movement origin cell have the same value. The base station receiving the TAI change request message from the monitor control server changes its own TAI value. After that, all mobile devices perform only handover when they move between the cells where the TAI values are changed, and does not perform location registration.

Abstract: In a 2D and 3D character determining process, the contents of display status information indicating a display status of a non-player character, such as a display position and display brightness, is confirmed. It is then determined whether or not the display status of the non-player character satisfies a non-display condition. In the case where it is determined that the non-display condition is satisfied, it is determined that the character is not drawn in a virtual three-dimensional space. Subsequently, it is determined whether or not the display status of the non-player character satisfies a 2D display condition. In the case where it is determined that the 2D display condition is satisfied, it is determined that the character is drawn as a two-dimensional character. In the case where it is determined that the 2D display condition is not satisfied, it is determined that the character is drawn as a three-dimensional character.

Abstract: A wireless communication system including a wireless terminal, a plurality of base stations and a call processing control unit is disclosed. The wireless terminal, upon reception of the notification information from any of the base stations, judges whether the area included in the notification information is contained in the location registration area list stored in a storage unit, and in the case where the particular area is not so contained, sends a location registration request to the call processing control unit. On the other hand, the call processing control unit creates a new location registration area list based on the area included in the notification information and the neighboring areas, and sends the location registration area list to the wireless terminal.
