1 Scope
The present document contains the Test Suite Structure (TSS) and Test Purposes (TP) to test the HiperMAN/WiMAX
terminals based on the WiMAX Forum Network Architecture specifications.
The objective of the present document is to provide a basis for conformance tests for WiMAX terminal equipment
giving a high probability of air interface inter-operability between different manufacturers' WiMAX equipment.
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [21] and ISO/IEC 9646-2 [22]) as well
as the ETSI rules for conformance testing (ETS 300 406 [20]) are used as a basis for the test methodology.

Figure 1: TSS for WiMAX Forum Network architecture
The test suite is structured as a tree with the root defined as DLC-BS or DLC-MS representing the protocol groups
"DLC for BS" or "DLC for MS". The tree is of rank 3 with the first rank a Group, the second a Function, and the third a
sub-function. The third rank is broken down into the standard ISO conformance test categories CA, BV, BI, BO and TI
(discussed below).
NOTE: For compatibility with TP identifier names in earlier releases of the HiperMAN DLC Test Purposes
document, the protocol group "DLC for MS" in the present document is still denoted "SS".

4.2 Test groups
Each test group has a total of three levels. The first level is the protocol services. The second level separates the
protocol services into the various functional areas. The third level are the sub-functional areas. The fourth level, if
required, is used to indicate the initiator (BS or MS) or the direction of communication (DL or UL). This fourth level is
not shown in figure 1.
4.2.1 Protocol services
To be added in the next release.
4.2.2 Main test types
The main test types are the valid behaviour group, the invalid behaviour group and the inopportune behaviour group.
4.2.2.1 Valid Behaviour (BV) tests
This test group shall verify that the IUT reacts in conformity with the base specifications after receipt or exchange of
valid Protocol Data Units (PDUs). Valid PDUs means that the exchange of messages and the content of the exchanged
messages are considered as valid.
4.2.2.2 Invalid Behaviour (BI) tests
This test sub group shall verify that the IUT reacts in conformity with the base specifications after receipt of a
syntactically invalid PDU.
4.2.2.3 Inopportune Behaviour (BO) tests
This test sub group shall verify that the IUT reacts in conformity with the base specifications after receipt of a
syntactically correct PDU not expected in the actual message exchange.
4.2.2.4 Timer and counter (TI) tests
This test group shall verify that the IUT reacts in conformity with the base specifications after expiry of a defined timer
or counter.
5 Test Purposes (TP)
5.1 Introduction
5.1.1 TP definition conventions

are available to the IUT as a result of the NSP discovery procedure.
Expected Behaviour Check that: When the IUT has entered and performed successful authentication to
the selected NSP, the IUT indicates the selected NSP.
Test strategy
Notes Requires an upper tester.

TP ID TP/MS/NWE/BV-H0013
Reference WFNA Stage3 [3]: section 4.1.2.3.2.
PICS Item
Initial Condition The IUT is attempting network entry using automatic mode without user intervention
and more NSPs are available including the Home NSP.
Expected Behaviour Check that: The IUT initially selects and attempts authentication with the Home NSP
and if successful the IUT indicates the selected NSP.
Test strategy
Notes Requires an upper tester.

TP ID TP/MS/NWE/BV-H002
Reference WFNA Stage3 [3]: section 4.1.2.2, figure 4-1.
PICS Item
Initial Condition The IUT is attempting network discovery.
Expected Behaviour Check that when the IUT receives a SII-ADV or SBC-RSP with a Base Station ID with
the NSP Identifier flag set to ‘0' (indicating only one NSP associated with NAP) no
more NSP identification operations are performed.
Test strategy
Notes May be difficult to test.

5.2.2 DHCP group

RFC 2131 [8]: section 4.3.2.
PICS Item PIC_DHCPv4.
Initial Condition MS uses DHCP (and not MIP) for getting its PoA address from the network.
The MS has completed initial network entry procedures including authentication and
initial service flow (ISF) setup, i.e. initial connection establishment
(DSA-REQ/RSP/ACK).
Expected Behaviour Check that the IUT sends the DHCPDISCOVER message and that the message is
formatted per RFC 2131 [8].
Detailed observation results are described in [2] Stage 3: section 4.8.2.1.7.1.
