摘要:
A packet transferring/transmitting method is provided for use in a mobile communication system 50. In this packet transferring/transmitting method, an upper node 1 determines the implementation of handover (determination step), and a handover addressing node 2 transfers, of a plurality of packets, a non-transmitted residual packet to a handover addressed node 3, and the upper node 1 transmits a new packet to the handover addressed node 3 (transfer/transmission step). This enables maintaining the number of users to be accommodated while securing a wide bandwidth, sharing a line with high efficiency at soft handover, avoiding data residual in the case of the employment of variable communication rate, and preventing an increase in retransmission.

A mobile communication system includes a radio network control apparatus having inside a function block for processing a downlink shared channel and table means for storing various setting information related to the downlink shared channel communication and the downlink shared channel multi-cast communication. According to the information, a multi-cast communication (including uni-cast communication) is realized by using the downlink shared channel for one or more mobile apparatuses. Moreover, a base station has a function to transmit the downlink shared channel data and signaling data received from a radio network control apparatus, to a mobile apparatus via a radio line. Furthermore, it is possible to multi-cast data selectively to a particular mobile apparatus being call-connected.

A mobile terminal includes a reception unit to receive, from at least one of a plurality of communication systems, an initial beacon containing information for establishing communication according to each of the plurality of communication methods, a request unit to generate a request by use of the initial beacon to transmit the request to the at least one of the plurality of communication systems, and a determination unit to determine, based on information as a response to the request, the communication method and the frequency band, which are to be used in a time zone by the mobile terminal.
摘要:
In a mobile communication system, which has a plurality of radio network controllers and a number of radio base stations connected to each of the radio network controllers, for sending and receiving user data between a host network and mobile stations via the radio network controllers and radio base stations, a plurality of transmission paths that pass through one or more radio network controllers are set up between a base station, which sends and receives radio signals to and from a mobile station, and the host network. When data is being sent and received using one transmission path from the host network to a base station through a radio network controller, traffic conditions on this transmission path are monitored. When traffic has increased, the user data is dispersed by being passed through a plurality of transmission paths.
摘要:
A base station accommodation method and mobile communication system which allows the installation of many micro-miniature BTS devices are provided. The mobile communication system includes a plurality of base stations which accommodate a plurality of mobile terminals respectively; a plurality of first base station control devices, each of which accommodates a predetermined number of base stations out of the plurality of base stations; and a second base station control device which accommodates the plurality of first base station control devices, wherein each of the plurality of first base station control devices comprises, for supporting information identifying a mobile terminal, a mobile terminal data base to store identification information which identifies a base station to which the mobile terminal is subordinate, and a station data base to store an address of the base station.
摘要:

摘要:
A system for mobile communication includes a base station and a mobile station. The base station includes a first transmitting unit operable to transmit to a mobile station, identifying information for multicast data to be to the mobile station, and a second transmitting unit operable to transmit the data on a shared channel to the mobile station, wherein the data is identified by the information transmitted. The mobile station includes a first receiving unit operable to receive from the base station identifying information for the multicast data, and a second receiving unit operable to receive the data on the shared channel from the base station, by the information received.
