The Non-
39、Access Stratum is essentially unchanged from the UMTS Non-Access Stratum, as defined in ETSI TS 124 007 i.4 and ETSI TS 124 008 i.5, with some functional extensions to support new services, as described in ETSI TS 102 744-3-7 i.14 and ETSI TS 102 744-3-8 i.15. The Access Stratum of the satellite rad
40、io interface provides a set of services that directly support the UMTS Non-Access Stratum Control Plane entities (such as GMM and MM) and User Plane functions residing in the Core Network in the upper layers of the Mobile Terminal. ETSI ETSI TS 102 744-1-3 V1.1.1 (2015-10) 7 As such there are a numb
41、er of requirements on the Access Stratum protocols to ensure that the attributes of the satellite link (high delay, variable error rate, aperiodic disruptions) are countered. The satellite Access Stratum is considered as a number of communication layers, as follows: Adaptation Layer (AL); Bearer Con
42、nection Layer (BCn); Bearer Control Layer (BCt); and Physical Layer (L1). Each layer communicates with its peer, the layer above and the layer below. For each layer there are a set of protocol unit definitions which are used to communicate with the peer. In addition between each layer there are a se
43、t of interface definitions which provide the mechanisms for control and transfer of information. An overview of the main functions of each of the layers of the Access Stratum is described in the present document, with the detailed specifications for the different layers provided in the sub-parts sho
44、wn in Table 4.1.

The Access Stratum and the Non-Access Stratum are separately indicat
46、ed in the diagram. The parts of the protocol stack that are modified for the Family SL satellite link relative to the standard 3GPP protocols are described in ETSI TS 102 744-1-1 i.6, clause 6.

Figure 4.2: Packet Switched User Plane Protocol Stack Layering For the Circuit Switched Domain, the lower layers (L1, BCt and BCn) of the protocol stack are identical, however, the PDCP an
48、d PPP/IP layers are replaced by the appropriate entity to provide Circuit Switched Services (e.g. Voice Codec or ISDN Interworking Function).

Each of the peer-layer entities exchanges a sequence of control messages called Signalling Data Units (SDUs) for the purpose of establishing, maintaining and terminating a connection. SDUs are always encapsulated within a Protocol Data Unit (PDU). Each Protocol Data Unit may contain a higher layer PDU and/
