Abstract
본 발명은 ISDN 사용자-망 접속의 LAPD에서 프리미티브 처리방법에 관한 것으로, 계층 2내부에서 T203타이머가 만료되어 발생된 T203 EXPIRY 프리미티브를 수신하는 단계(201); 상기 수신된 프리미티브의 링크엔티티를 식별하여 해당 링크 엔티티의 현재 상태를 판별하는 단계(202,203); 및 상기 판별결과 상태 7이면 확인대기절차를 수행한 후 재송카운터를 클리어시키고 타이머 복원상태로 천이하는 단계(204~207)로 구성되어 처리절차를 단순화하여 처리시간을 단축할 수 있는 효과가 있다.The present invention relates to a method for processing primitives in LAPD of an ISDN user-network connection, comprising: receiving a T203 EXPIRY primitive generated by an expired T203 timer in Layer 2 (201); Identifying (202,203) the current state of the link entity by identifying the link entity of the received primitive; And if the determination result state 7, the steps (204 to 207) of clearing the retransmission counter and performing the transition to the timer restoration state after performing the confirmation waiting procedure can be simplified to shorten the processing time.
