摘要:
A communication control device includes a parameter acquisition unit which acquires a first parameter determined on the basis of the number of mobile stations connected to the first cell or the number of mobile stations connected to the second cell, a parameter determination unit which changes the number of mobile stations connectable to the first cell or the number of mobile stations connectable to the second cell on the basis of the first parameter, and a parameter notification unit which notifies at least any one of the first base station and the second base station of the determined second parameter.

A disclosed base station apparatus to be used in a mobile communication system includes a report signal receiving unit receiving a report signal from one or more user equipment terminals, a radio parameter adjustment unit adjusting radio parameters based on an analysis result of each report signal, a designation unit designating a report condition to be used for each user equipment terminal to determine whether to transmit the report signal and content to be reported in the report signal, and a report unit reporting the report condition and the content to be reported to the one or more user equipment terminals. Further, in the base station apparatus, the report condition is satisfied when a transmission source of a downlink reference signal is a specific cell, and the content to be reported includes a received quality value of the downlink reference signal.

A trace reporting method, in which a user terminal reports to a tracking area management apparatus a trace along which the user terminal has moved in a mobile communication system, includes the steps of storing, by the user terminal, identifiers of base stations where the user terminal has performed cell selection in an identifier storage unit; and reporting, by the user terminal, to the tracking area management apparatus the identifiers stored in the identifier storage unit upon communicating with a base station. The tracking area management apparatus may compare the reported identifiers with a prestored pattern and assign a tracking area to the user terminal based on the comparison.

A data transmission system is disclosed for multicasting user common data from one or more radio base stations to one or more mobile stations. The radio base station is configured to transmit user common data using a shared data channel, transmit associated control information using an associated control channel, and transmit broadcast information using a broadcast channel. The mobile station is configured to receive the shared data channel, the associated control channel and the broadcast channel. The mobile station is further configured to analyze the broadcast information and the associated control information. The broadcast information includes information indicating transmission timing of the associated control channel. The associated control information includes information of a radio parameter of the shared data channel and includes distribution information indicating multicasting time of the user common data.

摘要:
A radio physical channel is available to multiple logical channels commonly, and multiple radio physical control channels are provided concomitantly with the radio physical channel and include a commonly usable common control channel. A channel transmission apparatus includes a logical channel type determination unit determining a type of a logical channel, and a channel transmission unit transmitting an identifier of the UE in the radio physical control channel depending on the type of the logical channel. A scheme of identifying the UE in the radio physical control channel is modified depending on the type of the logical channel.

A radio base station transmits user common data provided from a user common data control apparatus connected to a communication network to a plurality of mobile stations by radio. The radio base station includes a frame loss detection unit configured to detect loss of user common data that occurs on a transmission route between the radio base station and the user common data control apparatus, and a timing adjustment unit configured to change transmission timing of the user common data for the mobile station according to the loss of the user common data.
摘要:
A base station used in a packet transmission system in which shared user data to be selectively received by a user are transmitted using a shared data channel from one or more base stations to one or more mobile stations is provided. The base station includes means configured to provide user control data associated with transmission of the shared user data; means configured to provide notification data that include notification information used to select the shared user data and group identification information for specifying the notification information; and means configured to generate an associated control channel that is associated with the shared data channel and includes the user control data and the notification data, the associated control channel and the shared data channel being transmitted from the base station to the mobile station. The generated associated control channel is transmitted from the base station to the mobile stations.
摘要:
A downlink packet scheduling method is disclosed for a shared channel or a common channel in a mobile communication system between a base station and a mobile station, the method including a step in which the base station determines whether there is a waiting packet to be transmitted to the mobile station other than a current transmission packet; a step in which when it is determined that there is no waiting packet to be transmitted, the base station sets a stop period “t” in which packet transmission is temporarily stopped after the current packet transmission; a step in which the base station transmits information indicating the stop period “t” through a schedule information channel transmitting schedule information of downlink packets; and a step in which the base station stops the packet transmission to the mobile station during the stop period “t” after the current packet transmission.
摘要:
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.
