Patent ID: 7245591

Claim:
A data translation apparatus between a base station using an Internet protocol and a cell controller using an asynchronous transfer mode data in a mobile communication system, the apparatus comprising: a plurality of line interface units performing a data connection with said cell controller using asynchronous transfer mode data; a physical layer processor receiving data from said line interface unit and performing cell mapping on data received from said line interface unit; a universal test and operations physical layer protocol interface for asynchronous transfer mode (UTOPIA) switch connected to said physical layer processor, for performing a switching process for transmitting data between a base station controller and a base station; a data translator for translating data to be transmitted to said UTOPIA switch into asynchronous transfer mode adaptation layer 0 data, and for translating data to be transmitted to said Internet protocol base station into Ethernet data; a plurality of repeaters for transceiving data between said Internet protocol base station and said data translator; a UTOPIA mapper connected to the UTOPIA switch, for performing as a UTOPIA interface on the data to enable data to be received from and transmitted to the layer converter; a layer converter for converting the data from the UTOPIA switch to any one of asynchronous transfer mode adaptation layer 0 data and asynchronous transfer mode adaptation layer 2 data; and a controller for controlling operations of said layer converter, said UTOPIA mapper, and said UTOPIA switch.
