• Abstract:

  The present document specifies the stage 3 description of the Supplementary Service Talking Party Identification (SS-TPI) for the Terrestrial Trunked Radio (TETRA). The SS-TPI supplementary service enables the party/parties participating in a call to receive the identification of the talking/sending party. The SS-TPI is activated against individual identity in individual call and against group identity in group calls.; Man-Machine Interface (MMI) and charging principles are outside the scope of the present document. The supplementary service stage 3 description is preceded by the stage 1 and the stage 2 description of the service, according to the method described in ITU-T Recommendation I.130 [10]. The stage 1 description specifies the service; from the user's point of view. The stage 2 description identifies the functional capabilities and the information flows needed to support the supplementary service as specified in its stage 1 description. The present stage 3 description specifies the protocols at the air interface and at the various Inter-System Interfaces (ISI) to support SS-TPI. ; NOTE: According to ITU-T Recommendation I.130 [10], 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 call or group call; more specifically to the following entities:; • the MS/LS of listening/receiving users during an individual call or a group call;; • to the originating Switching and Management Infrastructures (SwMIs) in an individual call or a group call;; • to the group home SwMI and the participating SwMI for a group call;; • to the terminating SwMI for an individual call;; • and, optionally, to the home SwMI of the group or of the MS/LSs involved, for managing the supplementary service.

SIST EN 300 392-12-3 V1.2.1:2006 is the Slovenian adoption of ETSI EN 300 392-12-3 for TETRA Voice plus Data. It specifies the stage 3 protocol support for the Supplementary Service Talking Party Identification (SS-TPI), so listeners in individual or group calls can receive the identity of the talking or sending party, and optionally the party’s mnemonic name and transmission-request priority.

What does SIST EN 300 392-12-3 V1.2.1:2006 specify?

SIST EN 300 392-12-3 V1.2.1:2006 specifies the network and protocol behaviour for SS-TPI at the air interface and across Inter-System Interfaces (ISI). It is written as a stage 3 service description, so it focuses on signalling, message content, and entity behaviour rather than user-interface operation or charging.

The document applies to Voice plus Data individual calls and group calls. It excludes Man-Machine Interface (MMI) and charging principles, so a buyer or implementer should use it for protocol design, implementation, conformance testing and interworking, not for end-user controls or billing rules.

The document is organized into:

• scope and references
• definitions and abbreviations
• service description
• signalling protocol and state definitions
• signalling procedures
• interactions with other services and ANFs
• informative annexes with examples and SDL

What are the key requirements of SIST EN 300 392-12-3 V1.2.1:2006?

SIST EN 300 392-12-3 V1.2.1:2006 defines how SS-TPI is activated, how talking-party information is carried, and how network entities exchange the related PDUs. In practice, implementers need to support the correct request, indication, and information flows for the call types and entities covered by the standard.

Service primitives and subscription control

Clause 4 defines the SS-TPI service primitives at the Supplementary Services service access point (TNSS-SAP). Authorized user MS/LS equipment can send ACTIVATE, DEFINE, INTERROGATE, and INTERROGATE BY NAME requests, while served user MS/LS equipment receives INFORM indications.

This matters because SS-TPI is not just a display feature - it is a controlled supplementary service. The standard allows an authorized user to set up SS-TPI for one identity or, optionally, lists and ranges of identities.

Information delivered to served users

Clause 4 and clause 5 define the information that can be delivered: the talking/sending party identity, optional mnemonic name, and optional TX demand priority. Clause 5 also states that SS-CLIR can suppress identity and mnemonic name delivery.

This matters because receiving stations must know when they can show the caller identity, when they must suppress it, and when they may also display the priority of the transmission request.

Call-type dependent procedures

Clause 5 distinguishes behaviour for group calls and individual calls, including half-duplex and duplex cases. The served user MS/LS receives SS-TPI information at call establishment and whenever transmission permission changes, using the relevant D-SETUP, D-CONNECT, D-TX GRANTED, D-TX INTERRUPT, or related ISI PDUs.

This matters because the same service behaves differently depending on whether the call is group or individual, and on who currently has transmission permission.

Network-side states and message coding

Clause 5 defines conceptual states such as TPI-Idle, TPI-Activated, TPI-Option-Name, and TPI-Option-TX-Priority for the controlling and served SwMI entities. It also defines the SS-TPI PDU types and the information elements used to encode activation status, interrogation results, failure causes, mnemonic names, and TX demand priority.

This matters because conformance depends on both correct state transitions and correct PDU content on the wire.

Interworking and mobility support

Clause 5 covers interworking with PSTN, ISDN and PISN, and interactions with other supplementary services and ANFs, including SS-CLIP, SS-CLIR, SS-CAD, SS-COLP, and ANF-ISIMM. It also defines SS-TPI profile and SS-TPI profile ACK information elements for mobility updates.

This matters because SS-TPI has to keep working across network boundaries and when a subscriber moves between SwMIs.

What terms does SIST EN 300 392-12-3 V1.2.1:2006 define?

• SS-TPI - Talking Party Identification, the supplementary service that identifies the party who is speaking or sending.
• SwMI - Switching and Management Infrastructure, the network entity that controls TETRA services.
• MS - Mobile Station, a TETRA user terminal.
• LS - Line Station, a fixed or line-connected TETRA station.
• ISI - Inter-System Interface, the interface between TETRA systems.
• PDU - Protocol Data Unit, the coded message exchanged between network entities.
• ROSE - Remote Operation Service Element, the mechanism used to carry remote operations over ISI.
• ANF-ISIMM - Additional Network Feature - Inter-System Interface Mobility Management, used for mobility-related profile exchange.

Who uses SIST EN 300 392-12-3 V1.2.1:2006?

SIST EN 300 392-12-3 V1.2.1:2006 is used by TETRA equipment vendors, network engineers, and conformance testers who implement supplementary services in Voice plus Data systems. It is also relevant to operators and integrators managing SwMI interworking, roaming, and call signalling.

In practice, the standard is used for:

• MS/LS protocol implementation
• SwMI call-control and supplementary-service logic
• ISI interworking between TETRA networks
• conformance testing at the TNSS-SAP boundary
• mobility/profile handling for subscribed users

• ITU-T I.130 - method for stage 1/2/3 service characterization.
• ITU-T Z.100 - SDL notation used in Annex B.

What does the SIST EN 300 392-12-3 V1.2.1:2006 document contain?

The document contains the service description, the signalling protocol requirements, state definitions, and detailed procedures for normal and exceptional operation. It also includes coding rules for PDUs and information elements, including mnemonic name handling, activation results, failure causes, and SS-TPI profile exchange.

Annex A gives worked message-sequence examples for group calls and individual calls. Annex B gives SDL representations for the main entities, which is useful for implementation and verification teams because it shows the control logic in a formal procedural form.

1 Scope The present document specifies the stage 3 description of the Supplementary Service Talking Party Identification
(SS-TPI) for the Terrestrial Trunked Radio (TETRA). The SS-TPI supplementary service enables the party/parties participating in a call to receive the identification of the talking/sending party. The SS-TPI is activated against individual identity in individual call and against group identity in group calls. Man-Machine Interface (MMI) and charging principles are outside the scope of the present document. The supplementary service stage 3 description is preceded by the stage 1 and the stage 2 description of the service, according to the method described in ITU-T Recommendation I.130 [10]. The stage 1 description specifies the service from the user's point of view. The stage 2 description identifies the functional capabilities and the information flows needed to support the supplementary service as specified in its stage 1 description. The present stage 3 description specifies the protocols at the air interface and at the various Inter-System Interfaces (ISI) to support SS-TPI. NOTE: According to ITU-T Recommendation I.130 [10], 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 call or group call; more specifically to the following entities: • the MS/LS of listening/receiving users during an individual call or a group call; • to the originating Switching and Management Infrastructures (SwMIs) in an individual call or a group call; • to the group home SwMI and the participating SwMI for a group call; • to the terminating SwMI for an individual call; • and, optionally, to the home SwMI of the group or of the MS/LSs involved, for managing the supplementary service. 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.

In an individual call, if SS-TPI is provided to the calling and the connected users: - if the call is half-duplex, whenever one of the two parties becomes the talking/sending user, the other party is the served user; - if the call is duplex, both of them are served users. served user SwMI: in the case of an individual call, SwMI where the served user is registered, or in the case of a group call, any SwMI where served users are registered different from the group controlling SwMI NOTE: The protocol specified for the start of the call in the present document for such SwMI applies independently of whether or not the/a served user is registered in that SwMI at that time (i.e. the user registered in that SwMI involved the call may be talking/sending at set-up time, and become served user only later during the call). talking/sending user: party to whom transmission permission has been granted during a group call or a half-duplex individual call SIST EN 300 392-12-3 V1.2.1:2006

ETSI ETSI EN 300 392-12-3 V1.2.1 (2004-02) 10 talking/sending user SwMI: SwMI where the talking/sending user is registered NOTE: That definition applies without restriction in the case of an individual call. In the case of a group call, the talking/sending user SwMI exists only when it is different from the group controlling SwMI, The protocol specified for the start of the call in the present document for such SwMI applies independently of whether or not the talking/sending user is registered in that SwMI at that time (i.e. the user registered in that SwMI involved the call may be listening/receiving at set-up time, i.e. thus the/a served user, and become talking/sending user only later during the call). In addition, the other definitions given in EN 300 392-9 [6] shall apply. 3.2 Abbreviations 3.2.1 General abbreviations For the purposes of the present document, the following abbreviations apply: ANF-ISIGC Additional Network Feature - Inter-System Interface Group Call ANF-ISIIC Additional Network Feature - Inter-System Interface Individual Call ANF-ISIMM Additional Network Feature - Inter-System Interface Mobility Management ANF-ISISS Additional Network Feature - Inter-System Interface Supplementary Service GTSI Group TETRA Subscriber Identity ISI Inter-System Interface ITSI Individual TETRA Subscriber Identity MS Mobile Station PDU Protocol Data Unit ROSE Remote Operation Service Element SS Supplementary Service NOTE: The abbreviation SS is only used when referring to a specific supplementary service. SwMI Switching and Management Infrastructure 3.2.2 Supplementary service abbreviations For the purposes of the present document, the following abbreviations apply: CAD Call Authorized by Dispatcher CLIR Calling/connected Line Identification Restriction COLP Connected Line identification Presentation TPI Talking Party Identification 4 SS-TPI service description 4.1 General SS-TPI enables a listening/receiving user in an individual or a group call to be provided with the identity of the talking/sending party, and on an optional basis, with its mnemonic name and/or with the level of priority of its request for transmission grant. This clause describes SS-TPI specific 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-TPI 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-TPI all the service primitives has been shown without a TNSS-TPI-prefix e.g. the TNSS-TPI-ACTIVATE request is shorten into an ACTIVATE request.

ETSI ETSI EN 300 392-12-3 V1.2.1 (2004-02) 11 4.2 SS-TPI services offered over the TNSSSAP NOTE 1: 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-TPI service primitives at the served user MS/LS TNSS-SAP shall be: - INFORM indication. The SS-TPI service primitives at the authorized user MS/LS TNSS-SAP shall be: - ACTIVATE request; - ACTIVATE indication; - DEFINE request; - DEFINE indication; - INFORM indication; - INTERROGATE request; - INTERROGATE indication; - INTERROGATE BY NAME request; - INTERROGATE BY NAME indication. Any user to whom SS-TPI is provided should have the possibility to use the INTERROGATE primitives mentioned above, limited to its own ITSI and to GTSIs of groups he is member of. NOTE 2: Formally, when such user is using the INTERROGATE primitives to know whether SS-TPI has been activated for him, and if yes with which optional subscription parameters, he is acting as a served user. While when he is using those primitives to know his mnemonic name, he is acting as a talking/sending user (since that name is going to be delivered to the served user(s)). However no difference has been made between the two cases, since during a call any user can be in turn a served user and talking/sending user. 4.2.1 ACTIVATE indication The ACTIVATE indication primitive shall be sent to the user application by the MS/LS CMCE over TNSS-SAP to inform it of the result of a previous ACTIVATE request. If the previous request has been addressed to a SwMI for more than one identity, that SwMI may send its corresponding response either in one single request which applies to all those identities or in multiple requests. The ACTIVATE indication primitive shall contain the SS-TPI parameters listed in table 1. Table 1: Parameters for the primitive ACTIVATE indication Parameter Indication Activation result M (see note 1) TETRA identity/identities M (see note 2) Activation state C (see notes 1 and 3) NOTE 1: There shall be only one activation result and one activation state per indication primitive. NOTE 2: It is optional to support more than one identity. NOTE 3: Conditional on the activation result.
ETSI ETSI EN 300 392-12-3 V1.2.1 (2004-02) 12 4.2.2 ACTIVATE request The ACTIVATE request primitive shall be sent to the MS/LS CMCE by the user application by over TNSS-SAP to activate SS-TPI. The activation process shall support one TETRA identity in a request. Optionally it may support a list and/or range of identities. Such identity/identities may be those of either individual users or of groups. The ACTIVATE request primitive shall contain the SS-TPI parameters listed in table 2. Table 2: Parameters for the primitive ACTIVATE request Parameter Request Access priority O TETRA identity/identities M (see note 1) Activation request M (see note 2) NOTE 1: It is optional to support more than one identity. NOTE 2: There shall be only one activation request per request primitive.
4.2.3 DEFINE indication The DEFINE indication primitive shall be sent to the user application by the MS/LS CMCE over TNSS-SAP to inform it of the result of a previous DEFINE request.
If the previous request has been addressed to a SwMI for more than one identity, that SwMI may send its corresponding response either in one single request which applies to all those identities or in multiple requests. The DEFINE indication primitive shall contain the SS-TPI parameters listed in table 3. Table 3: Parameters for the primitive DEFINE indication Parameter Indication Definition result M (see note 1) TETRA identity/identities M (see note 2) Activation state C (see notes 1 and 3) NOTE 1: There shall be only one definition result and one activation state per indication primitive. NOTE 2: It is optional to support more than one identity. NOTE 3: Conditional on the definition result.
4.2.4 DEFINE request The DEFINE request primitive shall be sent to the MS/LS CMCE by the user application by over TNSS-SAP to give a mnemonic name to a user. The definition process shall support one TETRA identity in a request. Optionally it may support a list and/or range of identities. Such identity/identities may only be those of individual users (since the groups have no mnemonic names). The DEFINE request primitive shall contain the SS-TPI parameters listed in table 4. Table 4: Parameters for the primitive DEFINE request Parameter Request Access priority O TETRA identity/identities M (see note 1) TETRA mnemonic name/names M (see note 2) Activation request C (see note 3) NOTE 1: It is optional to support more than one identity. NOTE 2: There shall be as many mnemonic names as there are identities. NOTE 3: There shall be only one activation request per request primitive.
ETSI ETSI EN 300 392-12-3 V1.2.1 (2004-02) 13 4.2.5 INFORM indication The INFORM indication primitive shall be sent to the user application by the MS/LS CMCE over TNSS-SAP as a result of SS-TPI operation. The INFORM indication primitive shall contain the SS-TPI parameters listed in table 5. Table 5: Parameters for the primitive INFORM indication Parameter Indication SS-CLIR invoked for talking/sending party M Talking/sending party identity C (see note 1) Talking/sending party mnemonic name O (see note 2) Tx demand priority O NOTE 1: Conditional on SS-CLIR not having been invoked for talking/sending party. NOTE 2: Shall not be present if SS-CLIR has been invoked for talking/sending party.
4.2.6 INTERROGATE indication The INTERROGATE indication primitive shall be sent to the user application by the MS/LS CMCE over TNSS-SAP to inform it of the result of a previous INTERROGATE request.
If the previous request has been addressed to a SwMI for more than one identity, that SwMI may send its corresponding response either in one single request which applies to all those identities or in multiple requests. The INTERROGATE indication primitive shall contain the SS-TPI parameters listed in table 6. Table 6: Parameters for the primitive INTERROGATE
