40、onnection Layer (BCn) is to provide a number of different data transport services to upper layers. Figure 4.1 illustrates the position of the Bearer Connection Layer within the Family SL air interface protocol stack. An overview of the radio interface layering and relationship to the Bearer Control

41、Layer is provided in ETSI TS 102 744-1-3 5, clause 4 and ETSI TS 102 744-3-3 9, clause 4. An overview of the Bearer Connection Layer operation is provided in ETSI TS 102 744-1-3 5, clause 6.

42、44-3-4 V1.1.1 (2015-10) 8 The Bearer Connection Layer is generic to the radio interface and is responsible for the following: Queuing; QoS Policing; QoS Monitoring; Segmentation and Re-assembly; Ciphering; and Selectable ARQ. The data transport services provided by the Bearer Connection Layer are us

43、ed to carry signalling and data PDUs across the satellite radio interface. Three main data transport modes are supported: Acknowledged Mode (AM) Transparent Mode (TM) Unacknowledged (Numbered Frame) Mode (UM) These are provided to the upper layers via a number of different service access points (SAP

44、). The control plane and user plane architecture of the Bearer Connection Layer is illustrated in Figure 4.2 and Figure 4.3 respectively. The following clauses describe the Bearer Connection Layer SAP primitives for the upper interface to the Adaptation Layer. The SAP primitives for the lower interf

45、ace to the Bearer Control Layer are described in ETSI TS 102 744-3-2 8. 4.1 Bearer Connection Layer Entities 4.1.0 General The Bearer Connection Layer consists of a Bearer Connection Manager and instances of one of four possible data handlers (COM_DH, AM_DH, NUM_DH and TM_DH) with their associated S

46、ervice Access Points (SAPs). The Control Plane of each UE consists of an AM_DH for the UE Specific Signalling connection, a COM_DH for managing the Common Signalling connection and a Bearer Connection Manager. On the RNC side, the Control Plane consists of multiple sets of AM_DH and Bearer Connectio

47、n Manager entities, one for each UE registered. It also has a COM_DH for each of the Primary Shared Access Bearer. ETSI ETSI TS 102 744-3-4 V1.1.1 (2015-10) 9 Figure 4.2: Bearer Connection Layer - Control Plane The User Plane of each UE consists of a Bearer Connection Manager and one data handler (e

48、ither TM_DH, NUM_DH or AM_DH) for each data connection that is set up. On the RNC side, the User Plane consists of multiple sets of these entities, one for each UE registered. Figure 4.3: Bearer Connection Layer - User Plane 4.1.1 Bearer Connection Manager (BCnM) The Bearer Connection Manager (BCnM)

49、 provides bearer connection management services to the Adaptation Layer via the CBCn-SAP. This includes the creation and removal of a particular connection, and the setting of its QoS parameters.
