scope:
The present document 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, interrogation and operation of the supplementary service. The Switching and Management Infrastructure (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). 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 ISI to several TETRA systems.
Man-Machine Interface (MMI) and charging principles are outside the scope of the present 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 flows 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 relating to all supplementary services are detailed in EN 300 392-9 [5].
