An object of the present disclosure is to provide a parking management apparatus and the like each adapted to control traffic congestion near parking lots and perform management of parking lots more efficiently. A parking management apparatus includes a parking-lot-inside-state measurement unit configured to measure a congestion state inside a parking lot, a determining unit configured to determine, based on the measured congestion state inside the parking lot, a location of issuance of an electronic numbered ticket for the parking lot, and an issuing unit configured to issue the electronic numbered ticket when the vehicle reaches a location in a neighborhood of the location that has been determined by the determining unit.

Parking management apparatus, parking management system, parking management method and non-transitory computer readable medium

Signal information acquisition means acquires signal information about a traffic light installed on a road. Video acquisition means acquires a video photographed near a first parking lot entrance facing the road. Prediction means predicts whether or not a queue of waiting vehicles will be formed near the first parking lot entrance based on the video near the first parking lot entrance and the signal information. Selection means selects, from among a plurality of the parking lot entrances including the first parking lot entrance, a parking lot entrance to which a vehicle is to be guided based on a result of the prediction performed by the prediction means. Notification means notifies the vehicle of the parking lot entrance selected by the selection means.

Information provision apparatus, system, method and computer readable medium

A radio terminal () can perform carrier aggregation using a first cell () of a first radio station () and a second cell () of a second radio station (). The first radio station () or the second radio station () transmits constraint information to the radio terminal (). The constraint information contains an information element necessary to specify a reception constraint and/or transmission constraint related to the first cell () and/or the second cell () when the carrier aggregation is performed. The reception/transmission constraint is a constraint related to downlink signal reception/uplink signal transmission by the radio terminal over one or more subframe periods of the primary cell () and the secondary cell (). It is thus, for example, possible to contribute to reduction in wasteful power consumption in the radio terminal in the carrier aggregation of a plurality of cells served by different radio stations.

Radio communication system, radio station, radio terminal, communication control method, and non-transitory computer readable medium

A radio network () and a radio terminal () are configured to, when the radio terminal () is using a first cell () served by a first radio station () as a primary cell and a second cell () served by a second radio station () as a secondary cell, change the secondary cell form the second cell () to a third cell () while keeping communication status information regarding the radio terminal () on the second cell (). It is thus, for example, possible to enable a communication service in the secondary cell to be continued after the secondary cell is changed when the radio terminal which is simultaneously using a plurality of cells served by different radio stations changes the secondary cell from a cell of one radio station to a cell of another radio station.

Radio communication system, radio station, radio terminal, communication control method, and computer-readable medium

A radio terminal () is used in a radio communication system () and communicates with a radio station (). The radio terminal () includes a measurement unit (). The measurement unit () operates to perform, using a terminal measurement procedure for executing a first terminal measurement corresponding to radio access technology applied to the radio communication system (), a second terminal measurement of a shared frequency shared by a plurality of radio systems including the radio communication system ().

In order to appropriately perform, in a mobile communication system including a plurality of mobile communication networks respectively operated by a plurality of mobile communication operators, cooperation among respective mobile communication networks, a systemincludes a control apparatus including a second control unit that performs, via a first mobile communication networkoperated by a mobile communication operator A, for a second mobile communication networkoperated by a mobile communication operator B different from the first mobile communication operator A, control related to mobility for a terminal apparatus connected to the second mobile communication network, and a control apparatus including a first control unit that performs, not via another mobile communication network different from the second mobile communication network, for the second mobile communication network, control related to mobility for the terminal apparatus connected to the second mobile communication network

Mobile communication system and control method

A radio terminal can perform carrier aggregation using a first cell of a first radio station and a second cell of a second radio station. The first radio station performs, with the radio terminal, radio resource control for the first cell and the second cell in order to perform the carrier aggregation. Further, the first radio station transmits, to the second radio station, update information regarding an update to a configuration related to the radio resource control for the second cell. It is thus, for example, possible to prevent or reduce data transmission/reception failures which would otherwise occur while a configuration of radio parameters or the like is being changed by a radio terminal in carrier aggregation of a plurality of cells served by different radio stations.

A radio network () and a radio terminal () are configured to, when the radio terminal () is using a first cell () served by a first radio station () as a primary cell and a second cell () served by a second radio station () as a secondary cell, change the primary cell from the first cell () to a third cell () served by a third radio station () while keeping communication status information regarding the radio terminal () on the second cell (). It is thus, for example, possible to enable a communication service in the secondary cell to be continued even after the primary cell is changed when the primary cell is changed during execution of carrier aggregation (e.g., Inter-eNB CA) on a plurality of cells served by different radio stations.

A wireless communication system comprises: a setting notifying means for notifying, to a radio terminal, setting information related to at least one of the radio terminal's collection of measurement information and the radio terminal's reporting of the measurement information to a radio network; a status notifying means for notifying, to the radio network, a status related to at least one of the radio terminal's collection of the measurement information and the radio terminal's reporting of the measurement information; and a re-establishing means for receiving the status and determining whether to re-establish the setting information.
