4.1 Test architecture
The test architecture depicted in figure 1 is proposed. The aim of this test architecture is the testing of the access layer
which acts as the implementation under test (IUT). As the MI_SAP is considered a non-observable interface the
management entity is included in the system under test (SUT).

4.2 Radio Control and Observation Points
The following two testing reference points may be co-located in the same radio test equipment.
4.2.1 Radio Control Point PC_RTX
The radio point of control (PC) PC_RTX (Radio Transmission) will be used to trigger the entry of CCH and SCHs into
the different DCC_access states. This is done via an Upper Tester (UT) that sends an abstract service primitives (ASP)
of type SetDCC_AccessState to the Test System (TS). The UT will typically be realised within a radio test equipment.
The idea behind this is to stimulate the channelling probing functionality within the DCC access layer which will
inform the DCC management via the MI_SAP about the observed channel situation. DCC management will set the
transmission parameters based on the DCC_Access state. This is an indirect and non-transparent method of achieving
the entry into a DCC_Access state and to determine the transmission parameters for a given CH as the MI_SAP will not

be observed and furthermore there may exist a multitude of traffic situations that can be used at PC_RTX to stimulate
the transition to a DCC_Access state.
4.2.1.1 SetDCC_AccessState - Description
This ASP is used to set the DCC_Access state.

4.2.2 Radio Observation Point PO_RRX
The radio point of observation (PO) PO_RRX (Radio Reception) will be used to examine the traffic generated by the
SUT. This is done via a UT that receives ASPs of type Traffic_Characteristics from the TS.

4.3 Control and Observation Point PCO_IN for Triggering ITS
frames
TS 102 723-3 [3] and figure 4 in TS 102 724 [2] describe the IN-UNIDATA service for transport on the IN_SAP
between access and network & transport layer. The behaviour on the IN_SAP will be controlled and observed via the
point of control and observation (PCO) PCO_IN. Two testing ASPs are defined to request the transmission of frames on
the radio interfaces and to observe indications that may be received from the access layer. They are called IN_Request
and IN_Status and use a subset of the parameters defined in TS 102 723-010 [4] for the IN service primitives
IN-UNIDATA.request and IN-UNIDATA.status.
4.3.1 IN_Request - Description
This ASP is used to request the transmission of frames on the radio interface, see also TS 102 723-010 [4] clause 5.2.

TPs are numbered, starting at 001, within each group. Groups are organized according to the TSS.

= sequential number (01-99)

5.1.2 Test strategy
As the base standards TS 102 687 [1] contains no explicit requirements for testing, the TPs were generated as a result of
an analysis of the base standard of TS 102 723-3 [3], T S 102 723-10 [4] and TS 102 724 [2] and of the PICS
specification TS 102 917-1 [5].
5.1.3 TP structure
Each TP has been written in a manner which is consistent with all other TPs. The intention of this is to make the TPs
more readable and checkable. A particular structure has been used which is illustrated in table 6. Table 6 should be read
in conjunction with any TP, i.e. please use a TP as an example to facilitate the full comprehension of table 6.
