  • Publication number: 20110211471
    Abstract: This is a method for transmitting packets. The transmission method includes measuring a time taken for feedback indicating that a packet including context information has been lost; and switching between a first mode and a second mode based on the measured time taken for the feedback, the first mode being a mode for periodically transmitting a packet including the context information and the second mode being a mode for transmitting a packet including the context information in response to the feedback indicating that a packet including the context information has been lost.

  • Publication number: 20090304184
    Abstract: A mobile communication system that performs concealment processing of data between a wireless base station and a mobile station. The mobile communication system includes a concealment synchronization deviation detecting unit that detects concealment synchronization deviation between the mobile station and the wireless base station by detecting expansion failure of a compressed header after concealment release; and a concealment synchronization information notifying unit that notifies an opposite side of concealment synchronization information when the concealment synchronization deviation occurs.

  • Publication number: 20020072380
    Abstract: An inter-controller SW device, which broadcasts a message, or routes a message from a mobile station, is arranged between a base station controller and base station transceiver subsystem in a fixed wireless communications system, so that a communications path can be formed as the mobile station moves. In the fixed wireless communications system, the inter-controller SW device copies the message from the base station controller for which setting is made to make a mobile station belong to, and routes the message with a communication between inter-controller SW devices so as to allow a message to be transmitted also from a base station transceiver subsystem subordinate to a base station controller to which the mobile station does not belong, other than the base station controller to which the mobile station belongs. Additionally, a message from a mobile station that moves is routed with a communication between inter-controller SW devices, etc.

  • Patent number: 5923856
    Abstract: A control system for a communication apparatus has capability of coping with bus extension. The control system includes a control section and a plurality of controlled sections connected to the control section via a bus. Each controlled section accommodates at least one object to be controlled. The control section has a first interface for extension bus generation which includes a latch section and a bus transmission section. The controlled section has a second interface section for extension bus generation which includes a reception section, a judgment section, and a permission signal send-back section. The bus is formed by a bus which complies with a standard regarding mutual connection between apparatuses in a data communication system so as to send and receive pieces of information, each including a predetermined number of bits, and control signals. This makes it possible to suppress the hardware cost of channel sections and to efficiently perform highly functional monitoring and controlling.
