1 Scope
This European Telecommunication Standard (ETS) defines the stage 2 specification of
the Supplementary Service Barring of Incoming Calls (SS-BIC) for the Trans-European 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 this ETS.
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.
2 Normative references
This ETS incorporates, by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
affected user: Functional Entity 1 (FE1), the user on whose behalf the incoming services are barred.
SS-BIC is defined either for authorized user or for a group of which the authorized user is member.
authorized user: FE3, the user who is permitted to define SS-BIC on affected user's behalf.
basic service: Circuit mode speech service or circuit mode data service, see ETS 300 392-2 [1]
clause 11.
calling party: FE5, the party whose service request is barred due to SS-BIC.
Functional Entity (FE): Functional Entity performs the SS-BIC specific tasks in the MS, in the LS or in
the SwMI.
NOTE: In stage 2 specification the FE functionality is not restricted to SS sub-entity within
layer 3.
home system: The TETRA network which Mobile Network Identity (MNI) is equal to the user's MNI.
The SS-BIC definition is saved in the home system and home system is responsible for transporting
the SS-BIC definition to visited system(s).
Inter System Interface (ISI): The interface between two TETRA networks, that enables the inter-working
of services between these two systems.
Mobile Network Identity (MNI): Mobile Country Code (MCC) and Mobile Network Code (MNC) of
the TETRA Subscriber Identity (TSI).
Mobile Station (MS): A physical grouping that contains all of the mobile equipment that is used to obtain
TETRA services. By definition, a mobile station contains at least one Mobile Radio Stack.
packet data service: Connection oriented packet mode data service and connectionless packet mode
data service, see ETS 300 392-2 [1] clauses 24 and 26.
SS-BIC definition indication: The SS-BIC definition indication may be sent to the affected user(s) to
inform him about the definition made on his behalf or for a group of which he is member.
SS-BIC operation: The barring of a call in accordance with the SS-BIC definition.
Switching and Management Infrastructure (SwMI): all of the TETRA equipment for a Voice plus Data
(V+D) network except for subscriber terminals. The SwMI enables subscriber terminals to communicate
with each other via the SwMI.
visited system: The TETRA network which MNI is not equal to the user's MNI.

- all or certain incoming service types (basic or packet data services);
- restricted source addresses for incoming services.
The authorized user may request the SwMI to send the SS-BIC definition to the affected user for
information.
The SS-BIC definition made for an individual subscriber should be sent over the ISI as part of the mobility
management functions, when the subscriber migrates to the system.

Page 7Draft prETS 300 392-11-19: October 19961ScopeThis European Telecommunication Standard (ETS) defines the stage 2 specification ofthe Supplementary Service Barring of Incoming Calls (SS-BIC) for the Trans-European Trunked Radio(TETRA) as provided by European operators.SS-BIC enables barring restrictions for incoming services, e.g. calls, to be set. SS-BIC specifiesthe definition, interrogation and operation of the supplementary service. The Switching and ManagementInfrastructure (SwMI) applies the SS-BIC definitions when an incoming service is requested forthe restricted user. The SS-BIC actions are defined for the SwMI, for the Mobile Station (MS) and forthe 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 ISIto several TETRA systems.Man-Machine Interface (MMI) and charging principles are outside the scope of this ETS.Stage 2 describes the functional capabilities of the Supplementary Service introduced in stage 1description. Stage 2 identifies the functional capabilities for the management and operation of the servicein the SwMI, in the MS and in the LS. Stage 2 describes also the information flows exchanged betweenthese entities and the flows sent over the ISI.NOTE:The stage 2 description is followed by the stage 3 description, which specifiesthe encoding rules for the information flows and process behaviour for the differententities in the SwMI, in the MS and in the LS.2Normative referencesThis ETS incorporates, by dated or undated reference, provisions from other publications.These normative references are cited at the appropriate places in the text and the publications are listedhereafter. For dated references, subsequent amendments to or revisions of any of these publicationsapply to this ETS only when incorporated in it by amendment or revision.

By definition, a mobile station contains at least one Mobile Radio Stack.packet data service: Connection oriented packet mode data service and connectionless packet modedata service, see ETS 300 392-2 [1] clauses 24 and 26.SS-BIC definition indication: The SS-BIC definition indication may be sent to the affected user(s) toinform him about the definition made on his behalf or for a group of which he is member.SS-BIC operation: The barring of a call in accordance with the SS-BIC definition.Switching and Management Infrastructure (SwMI): all of the TETRA equipment for a Voice plus Data(V+D) network except for subscriber terminals. The SwMI enables subscriber terminals to communicatewith each other via the SwMI.visited system: The TETRA network which MNI is not equal to the user's MNI.SIST EN 300 392-11-19 V1.1.1:2003
