In a radio system which allocates resources using as units resource blocks which are formed by frequency components and time components, control information for mobile station devices, and identification information which is used to identify a format for a control information transmission channel which transmits the control information is transmitted from the base station device to the mobile station devices by means of the control information transmission channel.

Base station device, mobile station device, control information transmission method, control information reception method and program

Method and apparatus are provided for mapping an operating frequency band of a mobile station device in a mobile communication system. As operating frequency band position at the time of idle mode of respective mobile station devices is arranged so as to be distributed throughout a unique frequency bandwidth of a base station device.

Mobile station, base station and wireless communication method

In a method for mapping an operating frequency band of a mobile station device in a mobile communication system, an operating frequency band position at the time of idle mode of respective mobile station devices is arranged so as to be distributed throughout a unique frequency bandwidth of a base station device.

Mobile station device and method, base station device and method, and mobile station device operating frequency band mapping method

To effectively control information on allocation of a radio resource for each mobile station, improve the frequency use efficiency of the entire communication system, and effectively execute base station/mobile station control, a mobile station holds a Chunk Table (TB) in advance and successively receives the SCSCH (Shared Control Signaling Channel) of each predetermined available Chunk from the head of a radio frame. If the SCSCH has a mobile station identifier of the mobile station assigned, the mobile station receives an SDCH (Shared Data Channel) of the corresponding RB (Resource Block) and acquires a CID (Chunk ID). Here, user data may be simultaneously contained in the SDCH. The mobile station registers the acquired CID in the Chunk Table. Moreover, the base station side also has the Chunk Table corresponding to each mobile station and manages whether a CID has been allocated for each mobile station.

A smooth and seamless terminal switching guaranteeing continuity of communication at an application level is realized. A call control part for setting and managing a physical and logical transmission path between communication terminals, a session management part for managing establishment of data communication between the communication terminals, and a switching request processing unit for controlling interruption and resumption of a session are provided, wherein the switching request processing unit exercises a function to temporarily interrupt a session after receiving a session switching request signal from a communication terminal, a function to instruct the call control part to establish a call connection with a switch destination communication terminal, a function to establish a session with an application on the switch destination communication terminal, and a function to resume, after establishing the session, a session with a communication terminal of an opposite side.

Control system of communication network

To guarantee continuation of communications of the level of the applications, and implement smooth and seamless switching between communication terminals that execute the service. Provided are mobility management means () for performing call control and the like, service management means () for managing a session while controlling a start, suspension, resuming and releasing of session connection, and exerted are a function of receiving a switching request signal from the communication terminal of a switching source, and instructing the mobility management means () to perform call connection to the communication terminal of a switching destination that does not perform communications, another function of notifying the communication terminal of the switching destination of state information of the session executed between a communicating-apparatus communication terminal and the communication terminal of the switching source, and still another function of establishing new session connection between the communication terminal of the switching destination and the communicating-apparatus communication terminal.

Communication network control system, communication terminal, and communication network control method

A multimedia information recording device is used for efficiently recording multimedia information () file storage area () on a recording medium (). From the multimedia information given to the device, a data body DB and control information (HD and FD) are created and given to a file storage area writing section () where the data is written in parallel at a time on a free cluster in the file storage area. In the free area of each cluster where the data is written, dummy data is packed by a dummy data adding section () to absorb the difference between the first position of a cluster and the first position of the data in the cluster. Thus, data rewriting to eliminate this difference is avoided. Information for connecting plural clusters where data is written is created by a multimedia information file creating section (), and the multimedia information is recorded in a multimedia information file on the recording medium.
