A base station apparatus includes a determining unit that determines whether a direct link has been established between the base station apparatus and another base station apparatus, when a mobile device makes a request to switch a communication recipient from the base station apparatus to the other base station apparatus; a link information acquiring unit that acquires, indirectly from the other base station apparatus, link information necessary for establishing the direct link to the other base station apparatus, when the determining unit determines that no direct link to the other base station apparatus has been established; and a link requesting unit that requests the other base station apparatus to establish the direct link to the base station apparatus, based on the link information of the other base station apparatus acquired by the link information acquiring unit.

Base station apparatus, communication control system, communication control method, and inter-station control method

A wireless base station includes a candidate-cell obtaining unit that obtains a plurality of wireless communication route candidates usable for wireless communication of a mobile station with wireless base stations; a candidate-cell extracting unit that determines whether a wireless communication route candidate via which wireless communication can be performed is included in a plurality of wireless communication route candidates managed by the wireless base station itself from among the obtained wireless communication route candidates; a self-station determining unit; and a handover preparing unit that, when wireless communication can be performed via at least any of the wireless communication route candidates managed by the wireless base station itself according to the result of determination, notifies a wireless base station with which the mobile station is in wireless communication that wireless communication can be performed with the mobile station.

Base station apparatus, mobile station and wireless communication controlling method

A communication method in a communication system, wherein the communication system includes a mobile terminal, a communication server that distributes data to the mobile terminal, and plural base stations that are capable of relaying the data, and one of the base stations among the plural base stations is responsible for relaying the data. The communication method includes transmitting, to the communication server, restriction instruction information to restrict a data transmission rate, by a first base station that is responsible for relaying the data among the plural base stations, and hand-overing, by the first base station, causing a second base station different from the first base station to take over the responsibility of relaying.

A data transfer system includes a data conversion storage server () that generates data (MD) having a size smaller than a size of data (MD) received from a delivery server () by performing a specific process on the data (MD). A base station control unit () is provided with a data transferring portion that transfers one of the data (MDand MD) selectively to a mobile phone terminal (), and an approaching mobile communication equipment sensing portion that senses a mobile phone terminal () that is receiving the data (MD) and is approaching an HSDPA supporting wireless base station (). Then, the data transferring portion stops sending the data (MD) to the mobile phone terminal () sensed by the approaching mobile communication equipment sensing portion, and instead it starts transferring data (MD) related to a part of the first data to be transferred.

Data transfer system, approach notification system and data transfer method

A terminal regulation management device capable of flexibly managing terminals in times of unexpected incident, to ensure communications of users whose daily life zone overlaps with the site of the incident and of users whose daily life zone is outside the site. A priority information memory stores, with respect to each base station, priority information indicating priority levels as to subscribers' incoming/outgoing calls and including communication counts that the subscribers have communicated using their radio terminals. A communication information receiver receives communication information on the terminal communications from a radio network controller for controlling the base stations. A priority decision unit updates the communication counts stored in the memory, based on the received communication information, and determines the priority order of the priority information in accordance with the updated communication counts. A priority information transmitter transmits the priority information stored in the priority information memory to the base stations.

In a cell management method and apparatus which can prevent a call loss generated in association with an increase of cell usage rate independent of a protection frequency bandwidth, cell usage rates of operating cells (at frequency Fo) are acquired. Narrower nonoperating cells (at frequency Fo) of the operating cell in which the cell usage rate indicates a high-load state are rendered an addition candidate and the operating cell is rendered a deletion candidate. A broader nonoperating cell (at frequency Fo) of the operating cell in which the cell usage rate indicates a low-load state is rendered an addition candidate, and the operating cell and other narrower operating cells belonging to the nonoperating cell are rendered deletion candidate. From among the nonoperating cells that are the addition candidate and the operating cells that are the deletion candidates, a nonoperating cell(s) to be switched over to an operating cell(s) and an operating cell(s) to be switched over to a nonoperating cell(s) is determined.

Cell management method and apparatus

A method of management of location information for a mobile terminal in a mobile switching network ( ) having a subscriber accommodating center ( ) for accommodating a mobile terminal ( ) through a base station ( ) and a service control point ( ) located at a level higher than the subscriber accommodating center and managing the current position of all mobile terminals. Here, the location information for a mobile terminal in the service control point is fixed in accordance with a request from a subscriber of the mobile terminal, and a subscriber accommodating center having the mobile terminal under it stops the registration of the location information of the mobile terminal for the service control point.

System for management of location information for mobile terminal in mobile switching network

An apparatus and method for permitting temporary use of a telephone number which promptly permit temporary use of a different telephone number without requiring a telephone installation fee. Virtual telephone number notification unit assigns a virtual telephone number to a subscriber terminal at the request of the subscriber terminal, and virtual telephone number registration unit registers the thus-assigned virtual telephone number in association with connection information on the subscriber terminal. In response to call initiation by another subscriber terminal by means of the virtual telephone number, call connection unit refers to the virtual telephone number registration unit to read out the connection information associated with the virtual telephone number and, based on the connection information, connects the calling subscriber terminal to the first-mentioned subscriber terminal.

Apparatus and method for permitting temporary use of a telephone number

A traffic measuring apparatus provided in an exchange measures traffic caused by call control for a plurality of terminals accommodated in the exchange. The traffic measuring apparatus includes a traffic measuring section for measuring traffic in accordance with a predetermined measuring method, a load measuring section for measuring a call control load, and a measuring method change control section for changing the measuring method used in the traffic measuring section to a different measuring method in accordance with the call control load measured by the load measuring section. Accordingly, it becomes possible to perform detailed traffic measurement, while minimizing the load acting on the call control.
