Foreword This European Standard (Telecommunicati
14、ons series) has been produced by ETSI Project Terrestrial Trunked Radio (TETRA). The present document had been submitted to Public Enquiry as ETS 300 392-1 1-19. During the processing for Vote it was converted into an EN. The present document is part 11, sub-part 19 of a multi-part deliverable cover

19、ment defines the stage 2 specification of the Supplementary Service Barring of Incoming Calls (SS-BIC) for the Terrestrial Trunked Radio (TETRA) as provided by European operators. SS-BIC enables barring restrictions for incoming services, e.g. calls, to be set. SS-BIC specifies the definition, inter
20、rogation and operation of the supplementary service. The Switching and Management Infiastructure (SwMI) applies the SS-BIC definitions when an incoming service is requested for the restricted user. The SS-BIC actions are defined for the SwMI, for the Mobile Station (MS) and for the Line Station (LS)
21、. The SS-BIC information flows may be delivered over the Inter-System Interface (ISI). SS-BIC is invoked for incoming services within one TETRA system or for services that extend over the IS1 to several TETRA systems. Man-Machine Interface (MMI) and charging principles are outside the scope of the p
22、resent document. Stage 2 describes the functional capabilities of the Supplementary Service introduced in stage 1 description. Stage 2 identifies the functional capabilities for the management and operation of the service in the SwMI, in the MS and in the LS. Stage 2 describes also the information f
23、lows exchanged between these entities and the flows sent over the ISI. NOTE: The stage 2 description is followed by the stage 3 description, which specifies the encoding rules for the information flows and process behaviour for the different entities in the SwMI, in the MS and in the LS. Aspects rel
24、ating to all supplementary services are detailed in EN 300 392-9 5. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
