摘要:
One feature of the present invention relates to a base station for operating multiple cells each having a predefined bandwidth, including: a load measurement unit configured to measure traffic status in each of the cells; a selection probability computation unit configured to compute a selection probability used to select a preselected cell based on the traffic status, the preselected cell being accessed by a mobile station in transition from an idle state to an active state; a transmission unit configured to transmit the selection probability; and a control plane control unit configured to connect to the preselected cell being accessed by the mobile station.

A mobile station includes: means that performs discontinuous reception only for a signaling control channel, means that determines presence or absence of traffic data addressed to the own mobile station, and means that, when it is determined that there is traffic data addressed to the own mobile station, receives corresponding shared data channel. A radio access network apparatus includes: means that determines a discontinuous reception state, means that determines a discontinuous reception channel, means that reports the determined discontinuous reception channel to the mobile station, and means that, when transmission data arises, transmits a control signal using the determined discontinuous reception channel and that transmits traffic data using a corresponding shared data channel.

In order to decrease delay time until data sending and receiving for a mobile station that is registered and that is in an idle state, the system is configured such that, when the mobile station issues a request of a communication service, the mobile station specifies a requesting QoS identifier, and launches a validity verification procedure for the service request, and a procedure of a security mode setup is completed along with a response to the service request, and channel information assigned to the mobile station is reported.
摘要:
A method of transmitting cell information is disclosed. The method includes the steps of transmitting a primary broadcast channel at constant intervals in a cell of a mobile communications system; broadcasting, in the primary broadcast channel, scheduling information indicating a location of a first scheduling unit, including information to be broadcast in the cell; and broadcasting, in the first scheduling unit, information indicating whether the cell is a dominant cell or a subordinate cell.

摘要:
A disclosed mobile communication system includes a newly-installed base station configured to send its identifier and a pilot channel; existing base stations; user devices configured to send reception quality measurements of the pilot channel to the existing base stations; and an upper node. Each of the existing base stations includes a statistical processing unit for performing statistical processing on the reception quality measurements; and a statistical processing result reporting unit configured to send a result of the statistical processing to the upper node. The upper node includes a tracking area selecting unit configured to select a tracking area to be assigned to the newly-installed base station based on the results of the statistical processing; and a tracking area reporting unit configured to report the selected tracking area to the newly-installed base station. The newly-installed base station includes a tracking area setting unit configured to set the reported tracking area.
摘要:
A plug-and-play radio base station autonomously establishes X2 logical interfaces and S1 logical interfaces with existing base stations and upper nodes. A new radio base station which is installed in a network advertises an IP address of the new radio base station over a transport network. An existing radio base station or an upper node which receives the IP address detects the number of hops from the new radio base station to the existing radio base station or the upper node. An initial logical interface with the new radio base station is established when the detected number of hops is below a predetermined threshold.
摘要:
A base station in a mobile communication system is disclosed. In the mobile communication system, user devices present in areas covered by existing base stations report tracking area identifiers of tracking areas to which the existing base stations belong. The base station includes a statistical processing unit configured to count the number of the tracking area identifiers reported by the user devices for each of the tracking areas; and a tracking area selecting unit configured to assign the base station one of the tracking areas corresponding to the largest number of the tracking area identifiers counted by the statistical processing unit.
