Abstract: Disclosed is an automatic call conversion system based on location information, including: a sensor network for tracing a location of a telephone user in real time mode, and transmitting corresponding location information; a plurality of telephone terminals, each being implemented with a call forwarding function, for the telephone user; and an automatic call conversion apparatus for receiving the location information of the telephone user from the sensor network, selecting among the plurality of telephone terminals a telephone terminal for use in call receiving or call conversion by using the location information, and setting a speech path with the selected terminal or converting a call to the selected terminal. In this manner, call forwarding or call connection can be done more effectively.

Abstract: A home network system and a method of adjusting a data transmission rate in accordance with the state of a window executed in a client. The home network system performs a network matching between an external communication network and a home network. According to the system, the transmission rate of the data being transmitted to the client can be adjusted according to the operation states of the connected clients, the states of windows being executed in the respective clients and the kind of data being played in the respective windows. Therefore, even if the number of clients connected to the home network system or the number of windows being executed in the respective clients is increased, the whole data transmission speed of the home network system is not deteriorated and the transmission efficiency is not decreased.

Abstract: The present invention provides a terminal adapter for BISDN. The terminal that is applicable to both variable bit rate (VBR) ATM cells and constant bit rate (CBR) ATM cells for connecting a SB point to a R point. The terminal adapter can transfer and prioritize CBR and VBR ATM cells. The system uses a multiplexer/demultiplexer that is capable of determining an ATM cell type and capable of determining a priority of ATM cell types. The mumiplexer/demultiplexer determines priority among ATM cells and selects ATM cells among the both of VBR ATM cells and CBR ATM cells, and outputs the selected ATM cells to the said physical layer according to the determined priority when transmitting data from R point to SB point, or determines the type of ATM cell, and outputs VBR ATM cells to the ATM AAL3/4,5 layer, CBR ATM cells to one of the multiple CBR interfaces when transmitting data from SB point to R point.
