이동통신 기지국시스템의 각 프로세서간 통신방법{Communication method inter-processor of a mobile communication cell site system}Communication method inter-processor of a mobile communication cell site system

본 발명은 이동통신 기지국 시스템의 각 프로세서간 통신방법에 관한 것으로서, 특히 이동통신 시스템(IMT-2000, PCS, DCS)기지국내의 프로세서간, 제어국간, 제어국과 기지국간의 통신망을 10/100 이더넷(Ethernet)으로 구현함으로써, 규격화된 프로토콜(Protocol)의 제공을 통해 이더넷 접속을 지원하는 상이한 시스템간의 보다 나은 접속환경을 제공할 수 있도록 한 이동통신 기지국 시스템의 각 프로세서간 통신방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication method between processors of a mobile communication base station system, and more particularly, to a communication network between processors in a mobile communication system (IMT-2000, PCS, DCS) base station, a control station, a control station and a base station. By implementing in Ethernet, the present invention relates to a communication method between processors of a mobile communication base station system that can provide a better connection environment between different systems supporting an Ethernet connection by providing a standardized protocol.

이하, 종래 기술에 따른 이동통신 기지국 시스템의 각 프로세서간 통신방법에 대하여 첨부한 도 1을 참조하여 살펴보기로 한다.Hereinafter, a communication method between the processors of the mobile communication base station system according to the related art will be described with reference to FIG. 1.

도 1은 종래 기술에 따른 이동통신 기지국 시스템의 각 프로세서간 통신방법을 구현하기 위한 이동통신 시스템 구성을 나타낸 도면으로서, 제어국(10), 망(20), 다수의 기지국(30, 40, 50)으로 이루어진다. 여기서, 다수의 기지국(30, 40, 50)각각은 E1/HDLC(or TAXI)(E1/Highlevel Data Link Control)(Transparent Asyncronous Transmitter Receiver Interface)인터페이스(31), 라우터(32), 다수의 프로세서(33, 34, 35)로 이루어진다.1 is a diagram illustrating a configuration of a mobile communication system for implementing a method of communication between processors of a mobile communication base station system according to the prior art, and includes a control station 10, a network 20, and a plurality of base stations 30, 40, 50. ) Here, each of the plurality of base stations 30, 40, and 50 is an E1 / HDLC (or TAXI) (E1 / Highlevel Data Link Control) (Transparent Asyncronous Transmitter Receiver Interface) interface 31, a router 32, a plurality of processors ( 33, 34, 35).

제어국(10)은 교환국(미도시)과 기지국(30, 40, 50)간의 시스템으로서, 기지국(30, 40, 50)을 제어하는 역할을 수행하며, 다수의 기지국(30, 40, 50)은 제어국(10)의 제어에 따라 이동통신 단말기와 통신을 수행하는 역할을 수행한다.The control station 10 is a system between the switching center (not shown) and the base stations 30, 40, 50, and serves to control the base stations 30, 40, 50, and the plurality of base stations 30, 40, 50. Serves to communicate with the mobile communication terminal under the control of the control station 10.

그리고, 망(20)은 제어국(10)과 다수의 기지국(30, 40, 50)을 연결하는 것으로, E1링크를 지원하는 기간망이다. 이 망(20)은 기지국(30, 40, 50)과 제어국(10)간은 점대점 결선으로 기지국간의 통신은 제어국(10)을 통해 이루어진다.The network 20 connects the control station 10 and the plurality of base stations 30, 40, and 50, and is a backbone network supporting the E1 link. The network 20 is a point-to-point connection between the base stations 30, 40, 50 and the control station 10, and communication between the base stations is performed through the control station 10.

또한, 기지국(30, 40, 50)내의 E1/HDLC(or TAXI)인터페이스(31)는 제어국(10)과 기지국(30, 40, 50)간의 상이한 프로세서 통신을 지원하기 위한 접속부이고, 라우터(32)는 기지국(30, 40, 50)내의 각 프로세서간 HDLC(TAXI)통신패스를 설정하기 위한 부분이다. 여기서, HDLC(TAXI)는 현재 기지국(30, 40, 50)내의 프로세서간 통신용도로 사용되는 프로토콜이다.In addition, the E1 / HDLC (or TAXI) interface 31 in the base stations 30, 40, and 50 is a connection for supporting different processor communication between the control station 10 and the base stations 30, 40, and 50. 32 is a part for setting the HDLC (TAXI) communication path between the processors in the base stations (30, 40, 50). Here, HDLC (TAXI) is a protocol currently used for interprocessor communication in the base stations (30, 40, 50).

그리고, 기지국(30, 40, 50)내의 다수의 프로세서(33, 34, 35)는 기지국(30, 40, 50)내에서 서로 다른 프로세싱 동작을 담당하는 보드이다.In addition, the plurality of processors 33, 34, and 35 in the base stations 30, 40, and 50 are boards that are responsible for different processing operations in the base stations 30, 40, and 50.

이와 같이 이루어진 기존의 이동통신 기지국내에서 프로세서간 통신은 HDLC 또는 TAXI정합을 사용하여 통신 기능을 제공하였으나, 기지국(30, 40, 50)과 제어국(10)간의 접속은 E1정합을 사용하여 통신 기능을 제공한다.In the conventional mobile communication base station configured as described above, the inter-processor communication provides a communication function using HDLC or TAXI matching, but the connection between the base stations 30, 40, 50 and the control station 10 uses E1 matching. Provide the function.

프로세서간 통신이 시스템내에 한정적인 접속을 제공함으로서, 적용되는 보드로서의 기능에 부합하지 못하며 규격화되어 제공되는 보드 수준의 회로물들과 상호호환이 불가능하다. 또한 시스템수준의 기지국(30, 40, 50)과 제어국(10)간의 통신방법 또한 상이하기 때문에 그 차이를 극복하기 위한 프로토콜 변환회로 및 프로그램을 추가하여 시스템을 구성해야 되므로서 효율의 극대화에 장애요인으로 작용하게 되는 것이다.Because interprocessor communication provides limited connectivity within the system, it is not compatible with the functions of the board to which it is applied and is not compatible with the board-level circuitry provided. In addition, since the communication method between the base station (30, 40, 50) and the control station 10 at the system level is also different, it is necessary to add a protocol conversion circuit and a program to overcome the difference, thereby preventing the maximization of efficiency. It will act as a factor.

따라서, 본 발명은 상기한 종래 기술에 따른 문제점을 개결하기 위하여 안출한 것으로, 본 발명의 목적은 이동통신 시스템 기지국내의 프로세서간, 제어국간, 제어국과 기지국간의 통신망을 10/100 이더넷으로 구현함으로써, 규격화된 프로토콜의 제공을 통해 이더넷 접속을 지원하는 상이한 시스템간에 보다 나은 접속환경을 제공할 수 있도록 한 이동통신 기지국 시스템의 각 프로세서간 통신방법을 제공함에 있다.Accordingly, the present invention has been made to solve the above problems according to the prior art, an object of the present invention is to implement a communication network between the processor, the control station, the control station and the base station in the mobile communication system base station to 10/100 Ethernet Accordingly, the present invention provides a communication method between processors of a mobile communication base station system to provide a better connection environment between different systems supporting Ethernet connection through the provision of a standardized protocol.
