摘要:
A control method in a mobile communication system, that includes configuring a discard timer corresponding to a service data unit (SDU) for discarding the SDU according to a value of the timer; maintaining the value of the discard timer corresponding to the SDU when a handover is performed without restarting or resetting the value of the discard timer; and discarding the corresponding SDU when the maintained value of the discard timer reaches a given value.
摘要:
A mobile communication system, that includes a buffer storing packet data to be sent; and a controller configured for discarding the packet data according to a value of a timer corresponding to the packet data, maintaining the value of the timer corresponding to the packet data when a handover is performed without restarting or resetting the value of the timer, wherein the discarding further includes discarding the corresponding packet data when the value of the timer reaches a given value.

摘要:
A control method in a mobile communication system with a buffer unit for temporarily storing packet data to be sent, includes dropping the packet data stored in the buffer unit before sending when a drop timer corresponding to the packet data before sending reaches a given value or when a drop condition required by a drop mechanism accompanying the buffer unit is satisfied, and dropping the packet data stored in the buffer unit after sending when a drop timer corresponding to the packet data after sending reaches a given value.
摘要:
A transmitting apparatus that transmits data to a plurality of receiving apparatuses. The transmitting apparatus includes a transmission part that transmits information for extracting the data whose header is compressed, and a control part that controls the transmission part to transmit the information in a specified cycle to the one or more first receiving apparatus and to transmit the information to a second receiving apparatus at a timing independent of the specified cycle when that second receiving apparatus did not receive the information during the specified cycle.
摘要:
A network system including a mobile node, a correspondent node for transmitting/receiving a data packet to/from the mobile node, a first router to which the mobile node is connected at a visited domain and a second router to which the mobile node is connected at a moving destination to which the mobile node moves from the first router. The second router including a location registration message generating unit for generating a location registration message of the mobile node and transmitting the location registration message. The first router including a binding cache, a movement managing unit for receiving the location registration message and storing into the binding cache address information from before and after the mobile node moves and an encapsulating unit for receiving the data packet, encapsulating the data packet concerned, and creating and transmitting a data packet containing as a transmission destination the address information after the change.
摘要:
A wireless communication system includes a first base station; one or more second base stations having transmission power lower than the first base station; a mobility management apparatus for managing a location of a mobile terminal in a location registration area accommodating the first base station and the one or more second base stations. The mobility management apparatus includes a selecting unit that selects at least one of the second base stations transmitting a paging signal from among the one or more second base stations, and a paging unit that transmits a paging signal to the mobile terminal via the first base station accommodated in the location registration area, and the at least selected one of the second base stations.
