Title: Improvements in or relating to internet access
Inventor: MCCANN STEPHEN
IPC: H04L29/06
Filed: 2000-10-06
Granted: 2004-01-21
Abstract: A nested enhancer 22 located in a first network such as an internet 40 connects with a second nested enhancer 32 located in a second network such as a stub network or further internet. The nested enhancers form a pair with each knowing the IP address of the other. Each nested enhancer terminates any TCP connection that it receives from a stub network or internet host 20, and responds to the originating host as if it were the ultimate end system. The nested enhancer terminating the connection then 'tunnels' data in the TCP connection to its partner, which regenerates the connection to the end system. The tunnelling is preferably achieved with a dedicated IP tunnel. By applying a connection splitting technique rather than simple encapsulation of data allows performance enhancement in connection set-up time and flow control. The IP tunnel may pass through any number of enhancer pairs nested inside the outer pair and through a geostationary satellite link.

Title: Communication system for transferring data from a network interface to a radio interface
Inventor: KITO EIJI
IPC: H04W52/00
Filed: 2001-07-25
Granted: 2004-05-19
Abstract: An object of the present invention is to provide a communication system which can efficiently transfer data having a comparatively large capacity from a network interface through a radio interface. A mobile telephone is allowed to access a contents server from a base station through a mobile communication network and the Internet. Although the sum of electric power which the base station simultaneously transmits to all of the mobile telephones has an upper limit, the transfer rate to any mobile telephone that is transmitting or receiving large data are changed to a higher level, within a range of a margin. The electric power to the mobile telephone may be checked, and the data transfer rate may be increased when the checked electric power is small.

Abstract: An interface (4;12) between a data terminal (2;18) and a digital communications link (6,8,10) implements protocols and frame formats designed to reduce delays in a data communication with a remote terminal (18;2). The interface (4;12) overcomes the need to send or receive an HDLC SABME or UA control signal, and allows data to be sent over the digital communications link (6,8,10) as soon as the communication parameters are established. In a non-ARQ (error correction) mode, the interface (4;12) sends control signals and data over the communications link (6,8,10) in frames subdivided into many small subframes of fixed length, each subframe having a length code. The interface (12), when arranged for connection to the data terminal (18) through a telephone network (14), encodes call progress signals from the telephone network (14) for sending over the digital communications link (6,8,10). The interface (4;12) encodes and decodes interrupt signals for sending between the data terminal (2;18) and the digital communications link (6,8,10) when an interrupt signal is detected. <IMAGE>
