I Overview The Data Link Control (DLC) layer is layer 2b of the DECT protocol stack. The separation of the user information fiom the DECT signalling data is managed by

26、 the allocation of two independent planes: - - the Control plane (C-plane). the User plane (U-plane); and (3) Lower Network layer Figure 1: DECT protocol stack The U-plane is the part of the DLC implementation that is responsible for the transmission of the user data. The U-plane may provide a serie

27、s of different services and facilities, grouped into categories (LUX families). The C-Plane is the second part of DECT DLC and is mainly involved with the transfer of signalling information. It provides the means to support DECT Connection Oriented, Connectionless and Broadcast services (the broadca

28、st service exists only at the FT to PT direction). DECT DLC provides three classes of operation (Unacknowledged for CL services, Single frame and Multifiame for C/O services). At the DLC layer, C-plane and U-plane resources are considered as completely independent. The association of C and U-plane r

29、esources to serve a higher layer service (e.g. to setup and maintain a call) is a NWK layer responsibility. Moreover, no interaction is required between the services provided by each of the planes. Figure 2 shows the DLC (TSS) including its subgroups and defined for the conformance testing. ETSI STD

The first level creates two protocol groups representing the protocol plane. The second level separates the protocol plane in functional modules. The last level

32、 contains the standard IS0 subgroups CA, BV, BO and BI.

33、 C-plane protocol group is divided in four functional modules. The first functional module identifies the LAPC Class U services. The second functional module identifies the LAPC Class A services. The third functional module identifies the LAPC Class B services. The last functional module identifies

34、the broadcast services Lb. 4.3.1.2 U-plane The U-plane protocol group is divided in four functional modules. The first functional module identifies the Class O transmission procedures. The second functional module identifies the Class 1 transmission procedures. The third functional module identifies

35、 the Class 2 transmission procedures. The last functional module identifies the Class 3 transmission procedures. 4.3.2 Main test groups The main test groups are the Capability group (CA), the Valid Behaviour group (BV), the inopportune Behaviour group (BO) and the Invalid Behaviour group (BI). 4.3.2

36、.1 Capability (CA) tests This test sub group shall provide limited testing of the major IUT capabilities aiming to assure that the claimed capabilities are correctly supported, in accordance with the PICS. 4.3.2.2 Valid Behaviour (BV) tests This test sub group shall veri that the IUT reacts in confo

Valid PDUs, means, that the exchange of messages and the content of the exchanged messages are considered as valid. 4.3.2.3 Inopportune Behaviour (BO) tests This test sub group shall veri that the IUT is capable o

Such an event is syntactically correct but it occurs when it is not expected. 4.3.2.4 Invalid Behaviour (BI) tests This test sub group shall veri that the IUT reacts in conformity with the standard, on receipt of a syntactically invalid
