  • Patent number: 8185159
    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 thereby to execute the paging process.

  • Patent number: 7953406
    Abstract: An access point diagnosis unit 201 controls a radio access terminal portion 213 included in the access point 100, to execute a test of connection with the access point 100. A switch within the access point selectively connects the radio access terminal portion 213, with any of an antenna and radio reception parts of the own access point 100. In accordance with a failing part, the failure information which contains the failing part and/or a failure content is transmitted from the radio access terminal portion 213 to the radio access terminal 108 (1) along a first path tracing the radio reception part connected by the switch, etc. of the access point 100, or (2) along a second path tracing the antenna connected by the switch and the other access point 101.

  • Publication number: 20080020799
    Abstract: A notebook computer transmits a distribution. confirmation request including a content attribute. A data communication card performs a matching test for the attribute and notifies of a matching result. When a reservation receiving application requests to start reservation receiving, the data communication card synchronizes with a channel for broadcast to start transferring received data to the notebook computer, and switches a state display to STAND-BY state 2. The reservation receiving application sends a receiving end request upon detection of end of the content. The data communication card stops receiving the broadcast channel and returns the state display to STAND-BY state 1.
