47、TS applies to the TETRA Packet Data Optimised (PDO) radio air interface standard. It establishes the TETRA general network design of the TETRA PDO standard. It specifies the technical realisation of the Connection Oriented Network Protocol (CONP) and Specific Connectionless Network Protocol (SCLNP)
48、to provide the services on the network layer of the TETRA radio air interface. It defines the packet mode reference points for the Mobile Station (MS), Line Station (LS) and Network Management Unit (NMU). It specifies a model of the air interface protocol stack where the different functions of layer
49、s and sub-layers are described. This ETS defines the registration, authentication, mode change signalling and an overview of the functions of the Mobile link Entity (MLE) including roaming and migrating. It specifies the TETRA addressing and identities-and their organisation in groups corresponding to the different functions. The air interface protocol services, functions and interconnection protocol stacks are listed based on ISO/IEC 8473 l 13 and ISOAEC 8208 9. This ETS also gives guidance on priority in annex A, and Quality of Service (QoS) in annex B. 2 Normative references
