摘要:
A communication system includes a relay apparatus which offers an access link to a mobile terminal, a layer 2 switch which relays data between the relay apparatus and a router on a next hop from a communication destination terminal of the mobile terminal, and a route information notification unit. The route information notification unit notifies, to the relay apparatus and the layer 2 switch in a subnet where the mobile terminal is present, route information including a data link layer unicast address of a packet addressed to the mobile terminal, and a data link layer multicast address thereof in a case where the mobile terminal is activated and in a case where the mobile terminal switches a connection.
摘要:
A mobile communication system for providing mobile communication service by radio to a mobile station is disclosed. The mobile communication system comprises base stations having a function of controlling hand-overs and in-coming and out-going calls necessary for providing the mobile communication service, and a multi-cell controlling station having a function of managing radio resources of plural base stations forming radio cells and selecting an optimum base station, and a function of allocating radio resources to the base stations. When at least one of the base station controls an in-coming or out-going call or controls a hand-over, if its own radio resource usage rate is lower than a threshold, the base station selects a base station to be allocated without communicating with the multi-cell controlling station.

摘要:
A mobile communication system in which packets are transferred between network nodes for handing-over is disclosed. The mobile communication system comprises a packet data classifying unit that classifies packets based on a required transferring period; and a transfer controlling unit that transfers the classified packets, classification by classification, from an original network node to a destination network node. The packet data classifying unit classifies packets into a real-time-packet to be transferred in a real time manner or a non-real-time packet to be transferred in a non-real time manner.
摘要:
Disclosed is a communication system in which appropriate retransmission control operations are respectively performed for two data types including real time data and non-real time data, and the transmitter and the receiver used for this communication system. A data type identifier identifies a data type as real time or non-real time, and based on the identified data type, a controller, and another controller (not shown) adjust parameters used for retransmission control.

A mobile station is connectable to a first communication system for managing a service area with a respective first area and to a second communication system for managing a service area with a respective second area. The mobile station includes a first wireless communicator for receiving first notification information capable of specifying a current area and neighboring areas corresponding to the first communication system, a second wireless communicator for receiving second notification information capable of specifying a current area and neighboring areas corresponding to the second communication system, and a communication system selector for selecting the communication system for performing the communication, out of the first communication system and the second communication system, based on the first notification information or the second notification information.
摘要:
The logical channels are made to include a logical channel for control and a logical channel for data transmission, the radio physical channel are made to be commonly used for a plurality of logical channels, and one logical channel is made to have a correspondence relationship with one radio physical channel, and the channel assignment apparatus includes: traffic monitoring detection means that detects occurrence of traffic of the logical channels; and logical channel assignment means that, according to occurrence of the traffic of the logical channels, sequentially assigns required resources on the radio physical channel to the logical channels, so that the object is achieved.

An upper node and a handover source radio base station store setup information on an access bearer having been set up between the upper node and the handover source radio base station. A mobile communication method according to the present invention includes the steps of: (A) informing, from the handover source radio base station to a handover target radio base station, the access bearer setup information; (B) storing, at the handover target radio base station, the access bearer setup information informed of by the handover target radio base station; and (C) setting up, at the upper node, an access bearer between the upper node and the handover target radio base station by using the stored access bearer setup information without performing reallocation processing of new access bearer setup information, the access bearer being set up in response to a path switching request from the handover target radio base station.
