A reception apparatus which receives a first and second message includes a determination unit configured to determine correspondence between the first message and the second message, an acquisition unit configured to acquire data length information expressing a data length from the first message, and an extraction unit configured to extract data which has the data length based on the data length information from the second message when the determination unit determines that the first message corresponds to the second message.

Transmission apparatus and reception apparatus for message and method of data extraction

A processing apparatus for processing elements, which are contained in a message received via a network, by an application is provided. The apparatus includes a selection unit configured to select, in accordance with the number of elements contained in the received message, whether conversion of an element to a form  by the application is carried out in response to or prior to a request from the application, a storage unit configured to store an element, which is converted to a form by the application, in response to a request from the application, a read-out unit configured to read an element, which has been requested by the application, out of the storage unit, and a conversion unit configured to convert an element to a form by the application in response to and prior to a request from the application in accordance with the selection.

Processing apparatus and method

The present invention provides mobile terminals with various types of services such as electronic commerce service, music delivery service, and position information service. User applications required for the electronic commerce service, music delivery service, and position information service are respectively configured as service objects each having a server facility, and further a local gateway is provided, whereby various types of services can be used through a browser.

Information terminal

A flow processing apparatus generates second and third documents from a first document that describes a flow for executing services, registers the second document in a first apparatus and registers the third document in a second apparatus on the network on which the services exist. The flow processing apparatus then interprets the second document by the first apparatus and calls the second document by the first apparatus, interprets the third document by the second apparatus, which has been called from the first apparatus, and receives result of execution of a called service by the first apparatus.

Method of executing service on a network, and flow processing apparatus with document that describes a flow for controlling services on the network

Provided is an LED drive circuit capable of using a switching regulator IC having low breakdown voltage even when a power supply voltage is high. The LED drive circuit includes a voltage clamp circuit for clamping the power supply voltage to an operating voltage of the switching regulator IC, converts an output voltage of a current detecting circuit for detecting a current flowing through an LED into the operating voltage of the switching regulator IC, and outputs the operating voltage.

LED drive circuit

A memory stores a file attached to a message generated by using a structure language. Data containing an element contained in the message to which information for obtaining type information and a file referred by the element are obtained from the memory is added is constructed. This data has a construction corresponding to an application programming interface for the structured language.

Method and apparatus for processing messages

Provided is a new system for content use and settlement. A user requests a mobile telephone charge management server () to perform proxy settlement for goods purchased using mobile telephones(),() and(). The mobile telephone charge management server () makes an inquiry to a registration server () as to whether or not proxy settlement is possible. When proxy settlement is not possible, the mobile telephone performs settlement using electronic money that has been deposited therein.

Content use system, information terminal, and settlement system
