1 Scope
The present document contains the Abstract Test Suite (ATS) for Transmission of IP packets over Geonetworking as
defined in TS 102 636-6-1 [1] in compliance with the relevant requirements and in accordance with the relevant
guidance given in ISO/IEC 9646-7 [5].
The objective of the present document is to provide a basis for conformance tests for Transmission of IP packets over
Geonetworking equipment giving a high probability of inter-operability between different manufacturer's equipment.
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [2] and ISO/IEC 9646-2 [3]) as well as
the ETSI rules for conformance testing (ETS 300 406 [6]) are used as a basis for the test methodology.
Annex A provides the Tree and Tabular Combined Notation (TTCN) 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.

4 Abstract Test Method (ATM)
This clause describes the ATM used to test the Transmission of IP packets over Geonetworking.
4.1 Abstract protocol tester
The abstract protocol tester used by the IPv6OverGeonetworking test suite is described in figure 1. The test system will
simulate valid and invalid protocol behaviour, and will analyse the reaction of the IUT.

4.2 Test Configuration
The IPv6OverGeonetworking test suite uses a unique test configuration in order to cover the different test scenarios. In
this configuration, the tester simulates one ITS station implementing the IPv6OverGeonetworking protocol.

Both IUT and Test sytem are located in the GeoAreas associated with the three predefined GVLs. Each GVL is
associated with an IPv6 prefix which can be parametrised using module parameters.

4.3 Test architecture
This ITS IPv6OverGeonetworking test specification implements the general TTCN-3 test architecture described in
EG 202 798 [i.1], clause 6.3.2.
Figure 3 shows the TTCN-3 test architecture used in for the Geonetworking ATS. The IPv6OverGeonetworking test
component requires using only the Main Test Component (MTC). The MTC communicates with the
IPv6OverGeonetworking SUT over the ipv6OverGeoNetworkingPort and eoNetworkingPort. The
ipv6OverGeoNetworkingPort port is used to exchange IPv6 protocol messages between the test component and the
IUT. The geoNetworkingPort port is used to exchange GeoNetworking protocol messages between the test component
and the IUT.
The Upper tester entity in the SUT enables triggering IPv6OverGeonetworking functionalities by simulating primitives
from applications. It is required to trigger the IPv6OverGeonetworking layer in the SUT to send
IPv6OverGeonetworking messages, which are resulting from upper layer primitives. Furthermore, receiving
IPv6OverGeonetworking messages may result for the IPv6OverGeonetworking layer in sending primitives to the upper
layer.

4.4 Ports and ASPs (Abstract Services Primitives)
Three ports are used by the IPv6OverGeonetworking ATS:
• The geoNetworkingPort, of type GeoNetworkingPort.
• The ipv6OverGeoNetworkingPort, of type Ipv6OverGeoNetworkingPort.
• The utPort of type UpperTesterPort.
4.4.1 Primitives of the geoNetworkingPort
Two types of primitives are used in the geoNetworkingPort:
• The geoNetworkingInd primitive used to receive messages of type GeoNetworkingPacket.
• The geoNetworkingReq primitive used to send messages of type GeoNetworkingPacket.
4.4.2 Primitives of the ipv6OverGeoNetworkingPort
Two types of primitives are used in the geoNetworkingPort:
• The Ipv6OverGeoNetworkingInd primitive used to receive messages of type IPv6.
• The Ipv6OvergeoNetworkingReq primitive used to send messages of type IPv6.
4.4.3 Primitives of the utPort
This port uses two types of primitives:
• The UtInitialize primitive used to initialise IUT.
• The UtTrigger primitive used trigger upper layer events in IUT.
4.4.4 Primitives of the taPort
This port uses the following primitives to trigger special behaviour in Test Adapter:
• AcGn6InterfaceInfoList used to retrieve the list of IUT’s link-layer interfaces with their configured IPv6
adresses.
• AcGetLongPosVector used to retrieve IUT’s position (extracted from IUT’s beacon messages).
5 Untestable Test Purposes
This clause gives a list of TP, which are not implemented in the ATS due to the chosen ATM or other restrictions.

6 ATS conventions
The ATS conventions are intended to give a better understanding of the ATS but they also describe the conventions
made for the development of the ATS. These conventions shall be considered during any later maintenance or further
development of the ATS.
The ATS conventions contain two clauses, the naming conventions and the implementation conventions. The naming
conventions describe the structure of the naming of all ATS elements. The implementation conventions describe the
functional structure of the ATS.
To define the ATS, the guidelines of the document ETS 300 406 [6] was considered.
6.1 Testing conventions
6.1.1 Testing states
6.1.1.1 Initial state
All test cases start with the function f_prInitialState. This function brings the IUT in an "initialized" state by invoking
the upper tester primitive UtInitialize.
6.1.1.2 Final state
All test cases end with the function f_poDefault. This function brings the IUT back in an "idle" state. As no specific
actions are required for the idle state in the base standard, the function f_ poDefault does not invoke any action.
As necessary, further actions may be included in the f_poDefault function.
6.2 Naming conventions
