1 Scope
The present document defines the stage 3 description of the Supplementary Service Area Selection (SS-AS) for the
Terrestrial Trunked Radio (TETRA).
SS-AS enables the calling user to establish a call in restricting the area where the participating users in a group call or
the connected user in an individual call may be located.
Man Machine interface and Charging clauses are outside the scope of the present document.
Supplementary service specifications are produced in three stages according to the method described in
ITU-T Recommendation I.130 [i.1]. The stage 1 description specifies the service from the user's point of view (see
EN 300 392-10-8 [i.3]). The stage 2 description identifies the functional capabilities and the information flows needed
to support the service as specified in its stage 1 description (see EN 300 392-11-8 [i.4]). The present stage 3 description
specifies the protocols at the air interface and at the various Inter-System Interfaces (ISI) to support SS-AS.
NOTE: According to ITU-T Recommendation I.130 [i.1], the stage 3 description of any telecommunication
service addresses the network implementation aspects. Consequently it comprises two steps: the
specifications of all protocols at the various reference points involved in any of the service procedures
(notably the service operation) are the first step of the stage 3 description, and the specifications of the
functions of the corresponding network entities are its second step.
The latter have not been provided since they can be derived from the specification of the functional entity
actions in the stage 2 description.
The present document is applicable to Voice plus Data individual calls or group calls; more specifically to the following
entities:
- the MS/LS of the calling user in an individual call or a group call;
- the originating Switching and Management Infrastructure (SwMI) in an individual call or a group call;
- the group home SwMI and the participating SwMIs for a group call;
- the terminating SwMI for an individual call; and
- optionally, the home SwMI of the group or of the MS/LSs involved, for managing the supplementary service.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in EN 300 392-9 [5] apply with the following
modification:
authorized user: identified user who is allowed to define selected areas and to interrogate the infrastructure about the
existing defined selected areas
geographical definition: definition of an SS-AS area given by limits on a map
NOTE: In practice, due to the difficulty to describe mathematically any area shape, only circles and rectangular
areas are specified (see clause 5.2.2.12).
served user: user for whom the supplementary has been subscribed
NOTE: That user can thus successfully invoke the supplementary service.
served user SwMI: SwMI where the served user is currently registered
NOTE: In a call (whether an individual or a group call), the served user SwMI is the originating SwMI.
site definition: definition of an SS-AS area given as a list of base stations within one or more SwMI
NOTE: Such list may be implicit, e.g. area defined as a whole home SwMI with no visited SwMI (i.e. no
participating SwMI in the case of a group call, and no other terminating SwMI than such home SwMI in
the case of an individual call) (see clause 5.2.2.12).
SS-AS operation inhibition: calling user or important users are included into the call even in the case those are outside
the selected area

4 SS-AS service description
4.1 General
SS-AS enables the calling user to establish a call in restricting the area where the participating users in a group call or
the connected user in an individual call may be located. The calling user invokes SS-AS in using a selected area number
when he sets up the call. That number corresponds to a selected area the definition of which is known by the
infrastructure (i.e. some SwMI on the call path).
After a group call has been established, as an option, SS-AS may continue to operate to restrict the area where the
participating users may roam or migrate, thereby barring the call restoration attempt for that user.
This clause describes the SS-AS services offered by the Circuit Mode Control Entity (CMCE) at the Supplementary
Services service access point (TNSS-SAP) of the TETRA voice plus data layer 3 service boundary in a TETRA Mobile
Station (MS) or TETRA Line Station (LS). The SS-AS service access point is used in conformance testing as a
normative boundary in MSs and LSs.
NOTE: As the present document only deals with the SS-AS all the service primitives has been shown without a
TNSS-AS-prefix e.g. the TNSS-AS-DEFINE request is shortened into a DEFINE request.
4.2 SS-AS services offered over the TNSS-SAP
NOTE: As man-machine interface or user applications are outside the scope of the present document service
primitives are used to define information exchange to and from the standardized part of the MS/LS. Those
primitives may be only indirectly accessible.
The SS-AS service primitives at the served user MS/LS TNSS-SAP shall be:
- ASSIGN request;
- INVOKE request;
- INVOCATION FAILURE indication.
ETSI
12 ETSI EN 300 392-12-8 V1.2.1 (2010-07)
The SS-AS service primitives at the authorized user MS/LS TNSS-SAP shall be:
- DEFINE request;
- DEFINE ACK indication;
- INTERROGATE request;
- INTERROGATE ACK indication.
The served user should have the possibility to use the INTERROGATE primitives mentioned above, limited to its own
ITSI and to GTSIs of groups of which he is a member.
4.2.1 ASSIGN indication
The ASSIGN indication primitive shall be sent over the served user TNSS-SAP by the MS/LS CMCE to the served user
application to inform it about the definition of a selected area against the corresponding selected area number for either
an ITSI allocated to that MS/LS or the GTSI of a group of which the served user is a member.
When supported (since it is optional), the assignment process shall support one selected area in a request. Optionally it
may support a list of selected areas in a single request.
The ASSIGN indication primitive shall contain the SS-AS parameters listed in table 1.

Selected area definition(s) M (see note 2)
Acknowledgement requested from served user(s) O
NOTE 1: It is optional to support more than one selected area number.
NOTE 2: There shall be as many selected area definitions as there are selected area numbers.

When an acknowledgement is requested from the served user, it shall be sent by the served user MS/LS without
involving the user application (i.e. directly); hence there is no ASSIGN ACK request primitive.
4.2.2 DEFINE request
The DEFINE request primitive shall be sent over the authorized user TNSS-SAP by the authorized user application to
the MS/LS CMCE to define a selected area against the corresponding selected area number for an individual subscriber
or for a group.
When supported (since it is optional), the definition process shall support one selected area for one TETRA identity in a
request. That TETRA identity may be either that of an individual subscriber or that of a g

ETSI ETSI EN 300 392-12-8 V1.2.1 (2010-07) 9 1 Scope The present document defines the stage 3 description of the Supplementary Service Area Selection (SS-AS) for the Terrestrial Trunked Radio (TETRA). SS-AS enables the calling user to establish a call in restricting the area where the participating users in a group call or the connected user in an individual call may be located. Man Machine interface and Charging clauses are outside the scope of the present document. Supplementary service specifications are produced in three stages according to the method described in ITU-T Recommendation I.130 [i.1]. The stage 1 description specifies the service from the user's point of view (see EN 300 392-10-8 [i.3]). The stage 2 description identifies the functional capabilities and the information flows needed to support the service as specified in its stage 1 description (see EN 300 392-11-8 [i.4]). The present stage 3 description specifies the protocols at the air interface and at the various Inter-System Interfaces (ISI) to support SS-AS. NOTE: According to ITU-T Recommendation I.130 [i.1], the stage 3 description of any telecommunication service addresses the network implementation aspects. Consequently it comprises two steps: the specifications of all protocols at the various reference points involved in any of the service procedures (notably the service operation) are the first step of the stage 3 description, and the specifications of the functions of the corresponding network entities are its second step.
The latter have not been provided since they can be derived from the specification of the functional entity actions in the stage 2 description. The present document is applicable to Voice plus Data individual calls or group calls; more specifically to the following entities: - the MS/LS of the calling user in an individual call or a group call; - the originating Switching and Management Infrastructure (SwMI) in an individual call or a group call; - the group home SwMI and the participating SwMIs for a group call; - the terminating SwMI for an individual call; and - optionally, the home SwMI of the group or of the MS/LSs involved, for managing the supplementary service. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies. Referenced documents which are not found to be publicly available in the expected location might be found at http://docbox.etsi.org/Reference.

SSI Short Subscriber Identity SwMI Switching and Management Infrastructure 4 SS-AS service description 4.1 General SS-AS enables the calling user to establish a call in restricting the area where the participating users in a group call or the connected user in an individual call may be located. The calling user invokes SS-AS in using a selected area number when he sets up the call. That number corresponds to a selected area the definition of which is known by the infrastructure (i.e. some SwMI on the call path). After a group call has been established, as an option, SS-AS may continue to operate to restrict the area where the participating users may roam or migrate, thereby barring the call restoration attempt for that user. This clause describes the SS-AS services offered by the Circuit Mode Control Entity (CMCE) at the Supplementary Services service access point (TNSS-SAP) of the TETRA voice plus data layer 3 service boundary in a TETRA Mobile Station (MS) or TETRA Line Station (LS). The SS-AS service access point is used in conformance testing as a normative boundary in MSs and LSs. NOTE: As the present document only deals with the SS-AS all the service primitives has been shown without a TNSS-AS-prefix e.g. the TNSS-AS-DEFINE request is shortened into a DEFINE request. 4.2 SS-AS services offered over the TNSS-SAP NOTE: As man-machine interface or user applications are outside the scope of the present document service primitives are used to define information exchange to and from the standardized part of the MS/LS. Those primitives may be only indirectly accessible. The SS-AS service primitives at the served user MS/LS TNSS-SAP shall be: - ASSIGN request; - INVOKE request; - INVOCATION FAILURE indication.

ETSI ETSI EN 300 392-12-8 V1.2.1 (2010-07) 12 The SS-AS service primitives at the authorized user MS/LS TNSS-SAP shall be: - DEFINE request; - DEFINE ACK indication; - INTERROGATE request; - INTERROGATE ACK indication. The served user should have the possibility to use the INTERROGATE primitives mentioned above, limited to its own ITSI and to GTSIs of groups of which he is a member. 4.2.1 ASSIGN indication The ASSIGN indication primitive shall be sent over the served user TNSS-SAP by the MS/LS CMCE to the served user application to inform it about the definition of a selected area against the corresponding selected area number for either an ITSI allocated to that MS/LS or the GTSI of a group of which the served user is a member. When supported (since it is optional), the assignment process shall support one selected area in a request. Optionally it may support a list of selected areas in a single request. The ASSIGN indication primitive shall contain the SS-AS parameters listed in table 1. Table 1: Parameters for the primitive ASSIGN indication Parameter Indication Selected area number(s) M (see note 1) Selected area definition(s) M (see note 2) Acknowledgement requested from served user(s) O NOTE 1: It is optional to support more than one selected area number. NOTE 2: There shall be as many selected area definitions as there are selected area numbers.
When an acknowledgement is requested from the served user, it shall be sent by the served user MS/LS without involving the user application (i.e. directly); hence there is no ASSIGN ACK request primitive. 4.2.2 DEFINE request The DEFINE request primitive shall be sent over the authorized user TNSS-SAP by the authorized user application to the MS/LS CMCE to define a selected area against the corresponding selected area number for an individual subscriber or for a group. When supported (since it is optional), the definition process shall support one selected area for one TETRA identity in a request. That TETRA identity may be either that of an individual subscriber or that of a group. Optionally the definition process may support a list of selected areas in a single request. Still optionally it may support a list and/or range of identities. SIST EN 300 392-12-8 V1.2.1:2010
