1 Scope
The present document specifies the Abstract Test Suite (ATS) for the mobility functions of the Internet Protocol,
Version 6, as defined in the specifications [11] through to [14]. The ATS is based on the requirements defined in the
IPv6 requirements catalogue TS 102 559 [2], the IPv6 test purposes TS 102 595 [3] and written according to the
guidelines of TS 102 351 [1], ISO/IEC 9646-2 [5] and ETS 300 406 [9].
The objective of the present document is to provide a basis for conformance tests for IPv6 equipment giving a high
probability of inter-operability between different manufacturer's IPv6 equipments.
Annex A provides the Tree and Tabular Combined Notation (TTCN-3) part of the ATS.
Annex B provides the Partial Protocol Implementation Extra Information for Testing (PIXIT) Proforma of the ATS.
Annex C provides the Protocol Conformance Test Report (PCTR) Proforma of the ATS.
NOTE: Annex B provides only the PIXIT items relevant for the mobility functions of IPv6. It is therefore
necessary to also fill the core PIIXT item in TS 102 516 [15] to gain all PIXIT values needed to run the
mobility test campaign.

4 Abstract Test Method (ATM)
This clause describes the ATM used to test the IPv6 mobility functions as defined in the RFC specifications [11]
through to [14]. The three following configurations have been developed to test the three different types of IUT, home
agents (HA), mobile nodes (MN) and correspondent nodes (CN).
4.1 CF_MOB_01 mobility config for HA under test
PTC01 simulates RT01, HS02 and MN. PTC02 simulates RT03 and HS03/CN. MNOffHome and MNAtHome are
mutually exclusive. CF_MOB_01 is initialized with MNOffHome; this allows in the preamble to start to send Binding
Update Off Home. In the postamble, in order to empty the HA Binding cache, MNOffHome is not used anymore and
MNAtHome is created. MNAtHome empties then the HA Binding cache.

In the case where MNUT is in the visited net, RT02 proxies all communication (the tunneled HOT/HOTI) between

deregisters from CNUT in the postamble) passes through the HA. Communication between MNOffHome and CNUT
passes through RT04.

5 Untestable and not implemented Test Purposes (TP)
The ATS comprises 141 TC. Those were derived from a total of 161 TP.
5.1 Untestable TP
This clause gives a list of 19 TP, which are not implemented in the ATS due to the chosen ATM or other restrictions:
TP_MOB_1315_01, TP_MOB_1483_01, TP_MOB_1562_01, TP_MOB_1634_01, TP_MOB_1636_01,
TP_MOB_1638_01, TP_MOB_1639_01, TP_MOB_1645_01, TP_MOB_1661_01, TP_MOB_1674_01,
TP_MOB_1674_02, TP_MOB_1764_01, TP_MOB_1764_02, TP_MOB_1764_03, TP_MOB_3021_01,
TP_MOB_3029_01, TP_MOB_3053_01, TP_MOB_3053_02, TP_MOB_3058_01
5.2 Not implemented TP
TP TP_MOB_1631_01 has not been implemented, as the dynamic behaviour that validates its test purpose is already
implemented in TC_MOB_1615_01.
6 ATS conventions
Clause 6.1 describes the cleanup procedures used in this ATS.
Descriptions of the ATS conventions are found in TS 102 351 [1]. The ATS implementation details for the IPv6 core
test suite, including mapping procedures and ATS value conventions are found in TS 102 516 [15].

6.1 Security test cleanup
In the case where IKEv2 is used to negotiate the security associations, an INFORMATIONAL exchange with a Delete
Payload is executed as shown in figure 4.
In the case where security associations are configured manually, the security association has to be deleted manually
after a test case.

7 PCTR conformance
A test laboratory, when requested by a client to produce a PCTR, is required, as specified in ISO/IEC 9646-5 [7], to
produce a PCTR conformant with the PCTR template given in annex B of ISO/IEC 9646-5 [7].
Furthermore, a test laboratory, offering testing for the ATS specification contained in annex C, when requested by a
client to produce a PCTR, is required to produce a PCTR conformant with the PCTR proforma contained in annex A.
A PCTR which conforms to this PCTR proforma specification shall preserve the content and ordering of the clauses
contained in annex A. Clause A.6 of the PCTR may contain additional columns. If included, these shall be placed to the
right of the existing columns. Text in italics may be retained by the test laboratory.
8 PIXIT conformance
A test realizer, producing an executable test suite for the Abstract Test Suite (ATS) specification contained in annex C,
is required, as specified in ISO/IEC 9646-4 [6], to produce an augmented partial PIXIT proforma conformant with this
partial PIXIT proforma specification.
An augmented partial PIXIT proforma which conforms to this partial PIXIT proforma specification shall, as a
minimum, have contents which are technically equivalent to annex B. The augmented partial PIXIT proforma may
contain additional questions that need to be answered in order to prepare the Means Of Testing (MOT) for a particular
Implementation Under Test (IUT).
A test laboratory, offering testing for the ATS specification contained in annex C, is required, as specified in
ISO/IEC 9646-5 [7], to further augment the augmented partial PIXIT proforma to produce a PIXIT proforma
conformant with this partial PIXIT proforma specification.
A PIXIT proforma which conforms to this partial PIXIT proforma specification shall, as a minimum, have contents
which are technically equivalent to annex B. The PIXIT proforma may contain additional questions that need to be
answered in order to prepare the test laboratory for a particular IUT.

9 ATS conformance
The test realizer, producing a Means Of Testing (MOT) and Executable Test Suite (ETS) for the present document,
shall comply with the requirements of ISO/IEC 9646-4 [6]. In particular, these concern the realization of an Executable
Test Suite (ETS) based on each ATS. The test realizer shall provide a statement of conformance of the MOT to the
present document.
An ETS which conforms to the present document shall contain test groups and test cases which are technically
equivalent to those contained in the ATS in annex C. All sequences of test events comprising an abstract test case shall
be capable of being realized in the executable test case. Any further checking which the test system might be capable of
performing is outside the scope of the present document and shall not contribute to the verdict assignment for each test
case.
Test laboratories running conformance test services using this ATS shall comply with ISO/IEC 9646-5 [7].
A test laboratory which claims to conform to this ATS specification shall use an MOT which conforms to this ATS.
