A communication system according to the present disclosure includes: a required band calculation unit () configured to calculate a required band for a plurality of flows received by a bridge apparatus (), in which, for a flow including burst data among the plurality of flows, the required band calculation unit () calculates the required band for the flow based on a data size of the burst data and an allowable delay of the flow; and a speed ratio calculation unit () configured to calculate a relative ratio of communication speeds of the plurality of flows based on the required band for the plurality of flows. The bridge apparatus () transfers the plurality of flows to a data receiving apparatus () according to the relative ratio of the communication speeds.

Scalable data flows in a communication network

Provided are a mobile device and location registration method that, even when packet communications are being restricted and the location cannot be registered, the location can be registered rapidly when the access restriction is released. The mobile device comprises a packet timing unit that times a predetermined time; a location registration unit that registers the location to the control server for packet communications; a timing control unit that, if control server for packet communications is under access restriction, controls the timing operations to be temporarily stopped; and a location registration control unit that controls the location registration unit to register the location to the control server for packet communications, and also controls the location registration unit to register the location to the control server for packet communications if the control server for packet communications has released the access restriction and if the timing control unit has stopped the timing operations of the packet timing unit.

Mobile device and location registration method

A location name server is disclosed, that comprises a database for storing peripheral information and location names that have been correlated with each other as a plurality of sets, a means for transmitting a request for peripheral information to an objective cellular phone terminal unit when a request for the name of a location at which the object cellular phone terminal unit is located is received, a means for searching the database for the name of the location corresponding to peripheral information (i.e. electric field level) received from the objective cellular phone terminal unit corresponding to the request for the peripheral information, and a means for transmitting the obtained name of the location to a transmission source of the request therefor.

System for providing name of location at which cellular phone terminal unit is located

A portable telephone terminalhas a built-in memoryin which either the content of a new call arrived is recorded while continuing prevailing communication or recording of the content of the prevailing communication call is started while answering the new call. After the end of the communication, reproduction of the record in the built-in memoryin the portable telephone terminalis made possible immediately or at an appropriate time.
