이동무선시스템의 동기화방법Synchronization method of mobile wireless system

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 두개의 기지국 및 이동유닛을 예시한 개략도, 제2도는 TDMA 원리에 따라 전송 및 수신하는 타임도, 제3도는 제안된 방법에 따라 암호를 해독하는 타임도, 제4도는 제3도에 따라 주어진 시간 간격 동안 신호(KI)를 더욱 자세히 예시한 예시도.1 is a schematic diagram illustrating two base stations and a mobile unit, FIG. 2 is a time diagram for transmitting and receiving according to the TDMA principle, FIG. 3 is a time diagram for decrypting according to the proposed method, and FIG. Exemplary diagram illustrating in greater detail the signal KI for a given time interval accordingly.

Claims (5)

제1기지국(BS1)을 갖는 이동국의 통신을 제2기지국(BS2)에서 전송할 때 타임레퍼런스가 존재하지 않기 때문에 랜덤호름이 동기화를 상실할 경우 암호(E2)가 제1기지국에서 메세지를 제2기지국에서 전송하는 시간(t1-t3)의 주어진 주기 동안에 방해를 받는 것에 있어서, 상기 메세지(D, S)를 전환한 후 비암호신호(S1)가 제2기지국(BS2)에서 상기 암호가 다시 시작할때까지 통과하는 프레임간격(R2-R13)의 번호에 계수된 타임전(t3)에서의 이동국(M)S에 적용되는 것을 특징으로 하는 제1기지국(BS1)과 이동국(MS) 사이의 데이타메세지(D)와, 신호메세지(S)가 메세지 (D, S)위에서 임의로 선택한 비트흐름을 위치시켜 암호가된 타임슬롯을 갖는 프레임에서 전송되는 글로블타임래퍼런스가 부족한 이동무선시스템의 동기화하는 방법.When the random call loses synchronization because the time reference does not exist when the communication of the mobile station having the first base station BS1 is transmitted from the second base station BS2, the cipher E2 sends a message from the first base station to the second base station. In the case of being disturbed during a given period of time (t 1 -t 3 ) transmitted by the non-signal signal (S1) after the switching of the messages (D, S), the cipher is reset at the second base station (BS2). Data between the first base station BS1 and the mobile station MS, characterized in that it is applied to the mobile station M at time t3 counted to the number of frame intervals R2-R13 passed until it starts. A method of synchronizing a mobile wireless system that lacks a global time reference transmitted in a frame having an encrypted time slot by placing a message (D) and a randomly selected bit stream on the message (S). . 제1항에 있어서, 상기 시간점(t3)까지의 메세지(D, S)는 프레임간격과 같은 주기비트 순서를 구성하는 암호순서(E1)의 수단에 의해 전송되는 것을 특징으로 하는 이동무선 시스템의 동기화하는 방법.The mobile wireless system according to claim 1, wherein the messages (D, S) up to the time point (t 3 ) are transmitted by means of an encryption sequence (E1) constituting a cycle bit sequence such as a frame interval. How to sync. 제1항에 있어서, 상기 신호(S1)는 상기 메세지(D, S)를 전송하는 프레임(R2-R6)을 즉각 선행하는 프레임(R1) 동안에 나타나고 타임슬롯이 상기 프레임의 이동국(MS)에 할당되고 상기 신호(S1)을 수신할 때 이동국(MS)은 확인신호(A1)을 제2기지국(BS2)에 전송하는 것을 특징으로 하는 이동 무선시스템의 동기화하는 방법.The signal (S1) according to claim 1, wherein said signal (S1) appears during frame (R1) immediately preceding frames (R2-R6) that transmit said messages (D, S) and a timeslot is assigned to mobile station (MS) of said frame. And when receiving the signal (S1), the mobile station (MS) transmits an acknowledgment signal (A1) to the second base station (BS2). 제3항에 있어서, 만일 제2기지국(BS2)이 주어진 시간 경과후에 확인신호(A1)을 수신하지 못하면 비암호신호(S2)가 확인신호(A2)을 얻도록 처음에 언급한 신호(S1)와 같은 정보를 갖는 기지국에 의해 발생되는 것을 특징으로 하는 이동무선 시스템의 동기화 하는 방법.4. The signal S1 as claimed in claim 3, wherein the non-signal signal S2 obtains the confirmation signal A2 if the second base station BS2 does not receive the confirmation signal A1 after a given time elapses. Method of synchronizing the mobile wireless system, characterized in that generated by a base station having the same information. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
