6.4 Usage of DMA-UNITDATA primitive 6.4 Usage of DMA-UNITDATA primitive When clauses 6.2 and 6.3 refer to the DMCC "sending a PDU", the DMCC shall give the PDU to layer 2 in a DMA-UNITDATA request primitive. Layer 2 then transmits the PDU the appropriate number of times using the appropriate transmission method. Similarly, when the DMCC receives a PDU, the message is delivered by layer 2 in a DMA-UNITDATA indication primitive. Whe.. 더보기
7.3.1.2.1 DMA-REPORT primitive 7.3.1.2.1 DMA-REPORT primitive The DMA-REPORT indication shall be used by layer 2 to report on the progress or failure of a request procedure. DMA-REPORT indication 는 레이어 2에서 진행을 리포트하기위해 사용하거나 요구한 절차가 실패했다는걸 리포트 하기 위해서 사용했을 것이다. When layer 2 receives a DMA-UNITDATA request from layer 3, it shall generate a local identifier for the service request - referred to as the "handle to the request" - an.. 더보기
3 Definitions and abbreviations ETSI EN 300 396-3 V1.3.1 (2006-08) call: complete sequence of related call transactions between DM-MSs NOTE 1: There are two types of call, individual call or group call. An individual call is a complete sequence of related call transactions between two DM-MSs. A group call is a complete sequence of related call transactions involving two or more DM-MSs. The number of participants in a group call is not fixed. Participants may jo.. 더보기
7.4.19 Handle to the request 7.4.19 Handle to the request This shall be a local identifier which acts as a reference to a specific service request. Its implementation is outside the scope of the present document. local identifier 는 특정한 서비스 요청을 지시한다. 그것에 범위는 이문서 밖이다.. 더보기
4.2 The DM channel 4.2 The DM channel A DM call takes place on a "DM channel". In normal mode, only one DM channel may exist on a DM RF carrier. DM(Direct Mode) call은 "DM 채널"에서 발생한다. 기본 모드에서 하나의 DM 채널에 DM RF carrier 가 존재할지도 모른다. This DM channel is designated as channel A. 그 DM채널은 채널 A를 가르키고있다. In frequency efficient mode, two DM channels (designated channel A and channel B) may exist on a DM RF carrier. frequency .. 더보기
7.4.10A DM channel - ETSI EN 300 396-3 V1.3.1 (2006-08) 7.4.10A DM channel This parameter may be used, when appropriate, to indicate whether the primitive applies to channel A or channel B. 이 파라메터는 아마도 적절할 때 사용되었을 것이다. 프리미티브가 채널 A 나 채널 B 에 적용될때에 더보기
7.4.3 Call release - ETSI EN 300 396-3 V1.3.1 (2006-08) 7.4.3 Call release This parameter shall indicate call release to layer 2, e.g. when a user within a circuit mode call wishes to leave that call. 이 파라메터는 layer2에 call 을 release 하는걸 지시해야할 것이다. 그걸 언제 하냐면 사용자가 서킷 모드콜을 하는 중에 call을 끊기를 원할 때.... 그런단다. 그냥 TRUE, FALSE 로 주면되려나... 더보기
7.4.6 Circuit mode information - ETSI EN 300 396-3 V1.3.1 (2006-08) 7.4.6 Circuit mode information This parameter shall be used for layer 3 (the DMCC) to give instructions to the MAC when switching to traffic mode. It may comprise the following indications: • type of circuit (i.e. TCH/S, TCH/7,2, TCH/4,8, TCH/2,4); • interleaving depth N; • end-to-end encryption flag; • call type flag (i.e. individual or group call); • user device. 이 파라메터는 layer (DMCC) 을 위해 트레픽 .. 더보기
6.2.1.2 Incoming call (ETSI EN 300 396-3 V1.3.1 (2006-08), DMO) 6.2.1.2 Incoming call Notification of the arrival of an incoming call to the DMCC entity shall be made by the reception of a DM-SETUP PDU (delivered by layer 2 in a DMA-UNITDATA indication primitive). DMCC 엔티티에 콜이 오는걸 받았다면 DM-SETUP PDU 를 받아들여 만들어야 한다. (DMA-UNITDATA inidicaiton primitive 내에 layer2 에 의해 도착했을 때) If the "call type flag" in the DM-SETUP PDU is not appropriate to the destination addre.. 더보기
