Radio ATM transceiver

A radio ATM transceiver comprising:

• a radio modem for receiving and transmitting a radio packet;
• conversion means for performing mutual conversion between SONET frame signals and ATM cells;
• analysis means for analyzing signaling information extracted from the ATM cells to recognize a service class which is requested for ATM communication;
• speed control means for controlling a transmission speed of incoming signals thereof to coincide with a first transmission speed employed for the radio modem or a second transmission speed corresponding to the service class;
• and
• packet assembly/disassembly means for at a transmitting mode, assembling a number of ATM cells with an addition of a radio header to provide the radio packet which is forwarded to the radio modem, whereas at a receiving mode, said packet assembly/disassembly means disassembles the radio packet into the number of ATM cells which are forwarded to the speed control means.

A radio ATM transceiver which transmits ATM signals given via an ATM interface onto a radio line, comprising:

• a SONET framer which disassembles electric signals, which are supplied thereto from an optical fiber via the ATM interface, into ATM cells, said SONET framer also converting ATM cells, which are supplied thereto, into electric signals;
• a signaling analyzer which analyzes signaling information from the ATM cells so as to provide a number of the ATM cells which are assembled together for transmission onto the radio line as well as a bit rate employed for the ATM interface;
• a rate converter which converts a transmission speed of incoming signals thereof to coincide with a first transmission speed corresponding to a time series of ATM cells of the SONET framer of a second transmission speed corresponding to a bit rate employed for the radio line on the basis of an output of the signaling analyzer;
• and
• a packet assembler/dissassembler which assembles a number of the ATM cells, given from the rate converter, with an addition of header information to form a radio packet, which is then transmitted onto the radio line, said packet assembler/disassembler also disassembling the radio packet, given from the radio line, with excluding header information into ATM cells, which are then supplied to the rate converter.

A radio ATM transceiver comprising:

• a radio modern for receiving and transmitting a radio packet;
• a converter which performs mutual conversion between SONET frame signals and ATM cells;
• an analyzer which analyzes signaling information extracted from the ATM cells to recognize a service class which is requested for ATM communication;
• a speed controller which controls a transmission speed of incoming signals thereof to coincide with a first transmission speed employed for the radio modem or a second transmission speed corresponding to the service class;
• and
• a packet assembler/disassembler which, at a transmitting mode, assembles a number of ATM cells with an addition of a radio header to provide the radio packet which is forwarded to the radio modem, whereas at a receiving mode, said packet assembler/disassembler disassembles the radio packet into the number of ATM cells which are fonvarded to the speed controller.
