DATA COMMUNICATION INTERFACE DEVICE BETWEEN THIRD GENERATION AND SECOND GENERATION MOBILE COMMUNICATION SYSTEM

机译:第三代与第二代移动通信系统之间的数据通信接口设备

摘要

PURPOSE: A data communication matching apparatus between the third generation and the second generation in a mobile communication system is provided to secure the interface between the third generation IMT(International Mobile Telecommunication)-2000 system and a conventional mobile communication network by matching the third generation mobile communication system with the second generation mobile communication system. CONSTITUTION: An ATM matching unit(200) physically matches the third generation ATM wireless data of the third generation mobile communication system having a high-speed ATM transmission type. An ATM processing unit(300) receives the third generation ATM wireless data from the ATM matching unit(200), stores the third generation ATM wireless data in an ATM transmission region in a shared memory(100), and transmits an interrupt signal. An ATM control unit(400) assigns transmitting and receiving regions of an ATM information signal to the shared memory(100), and transmits the third generation ATM wireless data stored in the ATM transmitting region of the shared memory(100) to an HDLC transmitting region and transmits an ATM receiving acknowledge signal when receiving the interrupt signal from the ATM processing unit(300). An HDLC processing unit(600) receives the second generation HDLC wireless data from the HDLC matching unit(500), temporarily stores the second generation HDLC wireless data in the HDLC transmitting region in the shared memory(100), and transmits the interrupt signal. An HDLC control unit(700) assigns transmitting and receiving region of an HDLC information signal to the shared memory(100), and transmits the second generation HDLC wireless data stored in the HDLC transmitting region in the shared memory(100) to the ATM transmitting region and transmits the HDLC receiving acknowledge signal to the ATM control unit(400) when receiving the interrupt signal from the HDLC processing unit(600).
