1 Scope
The present document contains the Abstract Test Suite (ATS) for ITS GeoNetworking as defined in ETSI
EN 302 636-4-1 [1] in compliance with the relevant requirements and in accordance with the relevant guidance given in
ISO/IEC 9646-7 [i.6].
The objective of the present document is to provide a basis for conformance tests for ITS GeoNetworking equipment
giving a high probability of interoperability between different manufacturers' equipment.
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [i.3] and ISO/IEC 9646-2 [i.4]) as well
as the ETSI rules for conformance testing (ETSI ETS 300 406 [i.7]) are used as a basis for the test methodology.

4.2 Test Configuration
4.2.1 Test Configuration Overview
This clause introduces the test configurations that have been used for the definition of test purposes. The test
configurations cover the various scenarios of the GeoNetworking tests. The test configurations show:
• green ItsNode: ItsNode is in the communication range of the IUT.
• red ItsNode: ItsNode is not in the communication range of the IUT.
• dashed rectangle: definition of a specific geographical area (see note).
NOTE: A geographical area is defined in the GeoBroadcast or GeoAnycast packet by HST field of Common
Header and GeoAreaPos Latitude, GeoAreaPos Longitude, DistanceA, DistanceB and Angle fields of the
Extended Header.
Seven test configurations are defined below.

4.3 Test architecture
The present document implements the general TTCN-3 test architecture described in ETSI EG 202 798 [i.9],
clause 6.3.2 and clause 8.3.1.
Figure 9 shows the TTCN-3 test architecture used for the GeoNetworking ATS. In single-component testcases
(configuration CF01), the MTC is of type ItsNt and communicates with SUT over geoNetworkingPort. In
multi-component testcases (configuration CF02, CF03 and CF04), the MTC is of
