A computer receives, from a target device via a communication apparatus that is capable of accessing the target device, an issuance request for issuing key information unique to the target device. The computer generates the key information upon reception of the issuance request. The computer stores an address allocated to the communication apparatus and the key information in association with each other. The computer transmits the key information to the target device via the communication apparatus. The computer receives, from the communication apparatus, the key information and a registration request for registering a relay apparatus for relaying communication between the computer and the target device. The computer registers the communication apparatus as the relay apparatus when the address allocated to the communication apparatus and the address stored in association with the received key information match each other.

A communication system for calling a plurality of terminal devices in response to a single request of call connection, assigning, for a single terminal device which answered the call, a communication band to be occupied in a communication band which can be used, and establishing the call connection in the assigned communication band, the communication system includes a deriving section that derives a communication band required for the call connection of each of the terminal devices to be called when the request of call connection is received, a securing section that secures a communication band including the maximum width in each of the derived communication bands in the communication band which can be used; and an assigning section that assigns a communication band to be occupied in the secured communication band to the terminal device which answered the call.

Communication system, call control device, base station device and recording medium

If a call session has been established between terminal apparatuses on the sending side and receiving side when a voice packet is received from the terminal apparatus on the receiving side, a firewall apparatus sends the received voice packet to the terminal apparatus on the sending side. On the other hand, if a call session has not been established when a voice packet is received, the firewall apparatus starts buffering received voice packets. When a call session is established, the firewall apparatus sends the buffered voice packets to the terminal apparatus on the sending side.

Relay apparatus and memory product

A portable terminal includes a transmission unit, a reception unit, an operation mode judgment unit, an operation mode change unit. The transmission unit transmits first operation mode information including a first operation mode and a first setting time. The reception unit receives second operation mode information including a second operation mode and a second setting time. The operation mode judgment unit calculates a current degree of influence from the second operation mode on the first operation mode that decreases with time from the second setting time, and calculates an evaluated value of the current degree of influence from at least one operation mode including the second operation mode. The operation mode change unit changes, when the evaluated value exceeds a threshold value, the operation mode of the portable terminal to the second operation mode.

Portable terminal and method for controlling operation mode

In a presence system in which one user users a plurality of terminals, dynamically changing buddy lists are synchronized between the terminals. A presence notification message is sent to all the terminals of the user. The timing of sending includes, for example, when the presence information of a buddy is updated, when a new buddy is set, when display attribute information is updated, when a buddy is cancelled, and when a presence notification of unknown presentity is made. Thus, when one user uses a plurality of terminals in the presence system, dynamically changing buddy lists can be synchronized between the terminals. In addition, the display formats of the buddy lists do not differ from one terminal to another, and the same display format is attained.

Presence administration method and device

There is provided a base station apparatus which allocates communication bands for terminal units from an available communication band, and performs wireless communications with the terminal units using the allocated communication bands, including: a priority table storing priority information used for deriving a priority of the communication; a detecting part detecting a situation change concerning the communications; a band derivation part deriving communication bands required for the communications with terminal units to communicate, when the detecting part detects the situation change; a priority derivation part deriving priorities of the communications with the terminal units on the basis of the priority information stored in the priority table; and an allocating part allocating the communication bands derived by the band derivation part for the wireless communications with the terminal units in the order of descending priorities derived by the priority derivation part.

The object is to enable suppression of an excessive number of changes in assignment of a server in charge of communication in response to movement of a terminal. A position-information acquisition unit in a computer acquires information on the position of a mobile terminal as a candidate for a destination of information provision. Then, a zone determination unit determines whether or not the mobile terminal is in a coverage zone or a margin zone on the basis of the information on the position. An information provision unit starts the information provision to the mobile terminal when the mobile terminal enters the coverage zone, and ends the information provision to the mobile terminal when the mobile terminal goes out of the margin zone.
