A push-type information service to a client located within a local network and having only a local IP address becomes possible via a network address converting apparatus. A network address conversion program implementing the network address converting process may be stored on a storage medium. When assignment of an Internet IP address to a client is requested by a host server, an IP address assigning unit assigns an Internet IP address to that client. An address conversion table producing unit produces an address conversion table describing the correspondence between the Internet IP address assigned to the client and the local IP address of the client. An address converter notifies the host server of the assigned Internet IP address. After that, if the host server sends data to the acquired Internet IP address, the address converter converts the destination of the data to the corresponding local IP address of the client by referring to the address conversion table.

It is based on a user terminal having a fixed terminal and a terminal unit so that an Internet connection can be made by way of the terminal unit to an appropriate wireless server. The system has at least one wireless server connected to Internet; and a plurality of wireless station devices connected to the wireless server, and the system communicates wirelessly with the terminal unit of the user terminal; wherein one wireless server within a district of communication range of the wireless station devices is designated as a home server for the terminal unit, and the fixed terminal receives data sent wirelessly from Internet by way of the terminal unit.

Wireless server, system and method

A digital communication method and system wherein in response to input 3-bit data, a phase and amplitude of a carrier signal are controlled so that a symbol at a given time is located at one of allowed signal points depending on the content of the symbol. The allowed signal points include six signal points where a phase shift equal to .+-..pi./4, .+-.2.pi./4, or .+-.3.pi./4 occurs relative to the signal point at which the immediately previous symbol was located and where the amplitude is equal to a first level, and also include two signal points where a phase shift equal to .+-.2.pi./4 occurs relative to the signal point at which the immediately previous symbol was located and where the amplitude is equal to a second level lower than the first level. The digital communication method and system allows for a transmitter which does require a high-performance power amplifier, and a simplified receiver circuit. In addition, high-speed transmission can be achieved without expanding the bandwidth and high-reliability transmission is possible even in an environment having bad radio wave propagation as is the case in mobile communication.
