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 QoS server, that includes a receiver that receives a QoS setting request for a communication flow of a mobile terminal from not the mobile terminal but an application located on a network side; and a transmitter that transmits, in parallel, a QoS setting instruction based on the QoS setting request to both of a wireless access system mobile management node that accommodates the mobile terminal and a core network mobile management node that manages the wireless access system mobile management node.
摘要:
A communication system, including: a first mobile station; a first node; a first QoS server; a second mobile station; and a second QoS server, wherein the first node includes a first transfer unit which receives a QoS request for requesting to set a QoS channel from the first mobile station and transfers the QoS request to the first QoS server; and a management unit which instructs the first QoS server to transfer the QoS request if it is judged that the second mobile station is accommodated, the first transfer unit transfers the QoS request to the second QoS server based on the instruction from the management unit, and the second QoS server includes a QoS setting message output unit which outputs a QoS setting message to instruct setting of a QoS channel to said second mobile station based on the QoS request.
摘要:
A method including collecting position information indicating a position of an area to which a wireless communication service is not provided, transmitting the position information from the mobile terminal to a wireless base station using a random access procedure for setting up a communication channel between the wireless base station and the mobile station, and identifying the area which is within a cell range of the wireless base station and to which the wireless communication service is not provided.
摘要:
Identification information which identifies a specific area zone that is part of a cell of a radio base station is transmitted from the radio base station to a mobile terminal. Subsequently, when the mobile terminal is located at the area zone specified by the identification information, communication quality between the mobile terminal and the radio base station is measured by the mobile terminal, and the quality information indicating the measured communication quality is transmitted from the mobile terminal to the radio base station.
摘要:
A packet communication apparatus that carries out packet communication with a second packet communication apparatus via a logical connection through header processing of compressing or decompressing a packet header, the apparatus managing a first state machine of a first header processing state concerning a first packet flow of the connection and a second state machine of a second header processing state concerning a second packet flow of the connection; and controlling a state transition of a third state machine that is one of the first state machine and the second state machine on the basis of a state transition of a fourth state machine that is the other of the first state machine and the second state machine.
摘要:
A QoS server comprises a receiving unit that receives a QoS setting request for the communication flow of a mobile terminal; and a transmitting unit that simultaneously transmits a QoS setting instruction based on the QoS setting request to both of a wireless system mobile management node that accommodates the mobile terminal and a core network mobile management node that manages the wireless access system mobile management node.
