4 Adaptation Layer Interface
4.1 Radio Interface Layering
The satellite communication protocol is considered as a number of communication layers, as follows:
• Adaptation Layer (AL);
• Bearer Connection Layer (BCn); and
• Bearer Control Layer (BCt);
• Physical Layer (L1).
The satellite radio interface protocol stack is designed to seamlessly integrate with UMTS Non-Access Stratum entities,
such as GPRS Mobility Management (GMM) and Mobility Management (MM), residing in the Core Network (CN) and
in the upper layers of the User Equipment (UE).
The Adaptation Layer provides support to the UMTS Non-Access Stratum entities GMM and MM, and uses the
services provided by the Bearer Connection Layer, as shown in Figure 4.1. The present document defines the
Adaptation Layer peer-to-peer interface between the Radio Network Controller (RNC) and the UE, as shown in
Figure 4.1.

4.2 Conventions used in the present document
4.2.1 Presentation
The following conventions are applied throughout the present document:
• In the ASN.1, variable names are always in lower case letters with hyphenation used to improve readability
(e.g. ret-bct-pdu-header). Data Types in the ASN1. Always start with an upper case letter and may contain
additional upper case letters to improve readability (e.g. ReturnBCtPDUHeader).
• In the explanatory text these variables are referred to in italics (e.g. ret-bct-pdu-header) while Data Types are
shown in Helvetica typeface (e.g. BCnPDU).
The layout of the data structures defined in the ASN.1 is also shown in a graphical representation and gives examples of
the usage of these structures. In general, the variable names are presented in the same way they are presented in the
ASN.1, with the following exceptions:
• insufficient space does not allow the complete variable name to be presented and is therefore abbreviated;
• only one particular value can be assigned to a variable in the particular structure that is presented. In this case
the variable is replaced by the appropriate numerical value;
• additional information may be added in brackets for explanatory reasons.
4.2.2 "Reserved" Fields and Values
Fields shown as Reserved BITSTRING (.) in the ASN.1 structures shall be set to zero by the sender and shall be
ignored by the receiver.
Values not allocated in distinguished value lists shall not be used by the sender and shall be ignored by the receiver.
NOTE 1: Distinguished Value Lists of type Integer are being used instead of the ENUMERATED data type where
the allocated number range is larger than the number of items to be enumerated.
ETSI
10 ETSI TS 102 744-3-5 V1.1.1 (2015-10)
NOTE 2: It should be noted that UEs may only support a lower RI-Version than the one supported by the RNC (see
clause 6.1.2.2). In this case, it is likely that Broadcast SDUs/AVPs transmitted by the RNC contain values
that are considered as "reserved" by those UEs.
4.2.3 Boolean Variables
BOOLEAN variables shall be encoded as follows:
TRUE ::= 1
FALSE ::= 0
4.2.4 ASN.1 Encoding Rules
The ASN.1 presentation provided in the present document for this interface specification is normative. The encoding
rules used for this interface specification are provided in clause 4.3.4 of ETSI TS 102 744-3-1 [6].
5 Adaptation Layer
5.1 Overview
5.1.1 Responsibilities
The Adaptation Layer is responsible for the following:
• Registration Management: spot beam selection, system information handling, Non Access Stratum (NAS)
system information notification, registration and deregistration (with the RNC), GPS position reporting and
GPS position encryption.
• Mobility Management Support: providing RRC-like message transport and event notification services to
GMM in NAS as well as integrity protection and ciphering control.
• Radio Bearer Control: handling signalling related to setup, modification, and release of radio bearers,
configuring user plane protocol layers and entities and notifying NAS entities of resource assignments.
5.2 Adaptation Layer use of lower layer Service Access Points
To provide a seamless interface between the satellite network Access Stratum and the UMTS Non-Access Stratum,
functional equivalents for a number of UTRAN Radio Resource Control (RRC) messages have been defined. Each RRC
message is mapped to an equivalent message for the Satellite Radio Interface. Table 5.1 provides an overview of the
relationships between RRC Messages and the equivalent satellite radio interface Common Signalling Messages
(Unacknowledged Mode). Table 5.2 provides the same for the satellite radio interface UE Specific Signalling Messages
(Acknowledged Mode).

6 Adaptation Layer Protocol Data Units
6.0 General
The following clauses define the format of the Protocol Data Units which are used by the Adaptation Layer to signal its
peer (AL-PDUs). Clause 6.1 specifies those AL-PDUs which are sent through Common Signalling (AL-ComPDUs),
while clause 6.2 specifies those AL-PDUs which are sent on a UE Specific Signalling Connection (AL-SigPDUs).
6.1 Common Signalling Protocol Data Units (ALComPDUs)
6.1.0 General
Common Signalling PDUs are carried within a Common Protocol Data Unit (PDU) in the Bearer Control sub-layer,
where the type of the Common Signalling PDU is carried within the ComSigType field within a Bearer Control PDU
(see ETSI TS 102 744-3-1 [6]).

6.1.1 PagingType1
6.1.1.0 General
The PagingType1 Signalling PDU is used by the RNC when the UE is not registered to indicate that the UE should
initiate the Registration process. The Adaptation Layer shall inform the Non Access Stratum of the event. The PDU is
defined as below, with format shown in Figure 6.1.

6.1.1.1 CNDomainIdentity
This parameter identifies the Core Network Domain, which originated the paging request. The parameter definition is
the same as for the CNDomainIdentity Information Element (IE) specified in [3], clauses 10.3.1.1 and 11.3 as follows:
CNDomainIdentity ::=
INTEGER {
cs-domain (0),
ps-domain (1),
bm-domain (2),
} (0.3)
6.1.1.2 PagingCause
This parameter is also sent from the Core Network and hence follows the definition of the PagingCause IE in [3],
clauses 10.3.3.22 and 11.3 as follows:
PagingCause ::=
