ETSI ETSI EN 300 392-12-17 V1.1.2 (2002-01)6 1 Scope The present document specifies the stage 3 description of the Supplementary Service Include Call (SS-IC) for the Terrestrial Trunked Radio (TETRA). SS-IC permits the served user participating a call to include other participant to that call. Man-Machine Interface (MMI) and charging principles are outside the scope of the present document. Supplementary service specifications are produced in three stages according to the method defined in ITU-T Recommendation I.130 [1]. The stage 1 description specifies the service from the user's point of view (see ETS 300 392-10-17 [7]). 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 300 392-11-17 [8]). The present stage 3 description specifies the protocols at the air interface and at the various Inter-System Interfaces (ISI) to support SS-IC. NOTE 1: According to ITU-T Recommendation I.130 [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. NOTE 2: 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 and group calls; more specifically to the following entities: - the MS/LSs of the served user and of the affected user; and - the served user and the affected user Switching and Management Infrastructures (SwMIs) in an individual and group call. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.

ETSI ETSI EN 300 392-12-17 V1.1.2 (2002-01)8 4 SS-IC service description 4.1 General SS-IC enables a served user, while already participating in an active call (original call) to place a second call and have the participant(s) in this second call included in a group call together with the participant(s) in the original call. This clause describes the SS-IC 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-IC service access point is used in conformance testing as a normative boundary in MSs and LSs. NOTE: As the present document deals only with SS-IC, all the service primitives has been shown without a TNSS-IC- prefix e.g. the TNSS-IC-INVOKE request is shortened into an INVOKE request. 4.2 SS-IC services offered over the TNSS-SAP 4.2.1 General on service primitives 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-IC service primitives at the served user MS/LS TNSS-SAP shall be: - CANCEL request; - INVOKE request; - INVOKE indication; and
- INVOCATION FAILURE indication. The SS-IC service primitives for the affected user at the MS/LS TNSS-SAP shall be: - INFORM indication. The SS-IC service primitives for another user at the MS/LS TNSS-SAP shall be: - INFORM indication. 4.2.2 CANCEL The CANCEL request primitive may be sent over the served user TNSS-SAP by the user application to the MS/LS CMCE to cancel SS-IC invocation.
The CANCEL primitive shall contain the SS-IC parameters listed in table 1. Table 1: Parameters for the primitive CANCEL request Parameters Request Included party M

ETSI ETSI EN 300 392-12-17 V1.1.2 (2002-01)9 4.2.3 INFORM
The INFORM indication primitive may be sent over the affected or another user TNSS-SAP by the MS/LS CMCE to the user application to inform it that the presented call is an include call or that the current call is modified into an include call. There are no parameters in the INFORM indication primitive. NOTE: Actually the INFORM indication is carried as a notification indication of the basic call. 4.2.4 INVOKE The INVOKE request primitive shall be sent over the served user TNSS-SAP by the user application to the MS/LS CMCE to invoke SS-IC. The INVOKE indication shall be sent over the served user TNSS-SAP to the user application when the inclusion of the new party or parties has been completed. The INVOKE primitive shall contain the SS-IC parameters listed in table 2. Table 2: Parameters for the primitive INVOKE request and indication Parameters Request Indication Included party M M
NOTE 1: There are no other parameters as the call type is implied and the other relevant call parameters are the same as for the current call. NOTE 2: "called user alerted" is conveyed using the basic call primitives. 4.2.5 INVOCATION FAILURE indication The INVOCATION FAILURE indication primitive may be sent over the served user TNSS-SAP by the MS/LS CMCE to the user application to inform it about the failure of a previous INVOKE request. The INVOCATION FAILURE indication primitive shall contain the SS-IC parameters listed in table 3. Table 3: Parameters for the primitive INVOCATION FAILURE indication Parameters Indication Included party M Invocation failure cause M Disconnect cause M
4.3 Parameter description Disconnect cause: - any basic call disconnection cause. Invocation failure cause: - rejected for any reason; - not subscribed; - maximum number of inclusions already reached; - any basic call failure in the call set-up to the affected user (to be included user). NOTE: The maximum number of inclusions is outside the scope of the present document. SIST EN 300 392-12-17 V1.1.2:2003
