SIST EN 300 392-12-13 V1.2.1:2012 is the Slovenian adoption of the ETSI European Standard for Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D) supplementary services stage 3 for Call Completion to Busy Subscriber (CCBS). It specifies the network protocols, PDU coding, state behavior and signaling procedures that let a calling user request completion of a failed call when the busy destination later becomes free. The document is written for Mobile Station (MS) implementations, Switching and Management Infrastructure (SwMI) behavior, and interworking in TETRA V+D networks.
What does SIST EN 300 392-12-13 V1.2.1:2012 specify?
SIST EN 300 392-12-13 V1.2.1:2012 specifies the stage 3 description of SS-CCBS for TETRA V+D. In practice, that means it defines how the service is signaled between the served user MS and the network, and how the originating, terminating and group-controlling SwMI elements behave.
The scope applies to Voice plus Data individual calls and group calls. It is not applicable to Packet Mode of Operation or to DMO, and it excludes Man-Machine Interface (MMI) and charging principles.
The document is organized into:
- scope and references
- definitions and abbreviations
- service description over the TNSS-SAP
- signaling protocol support
- state definitions and signaling procedures
- interworking with public ISDN
- interactions with other supplementary services and ANFs
- timers
- Annex A SDL representation of procedures

What are the key requirements of SIST EN 300 392-12-13 V1.2.1:2012?
SIST EN 300 392-12-13 V1.2.1:2012 defines CCBS as a service where User A MS can ask the network to watch a busy user B and recall User A MS when user B is free. The practical point is that the standard fixes both the signaling exchange and the network state handling needed to complete the original call later without starting over.
Service behavior and service access
Clause 4 states that SS-CCBS is applicable to all basic circuit mode services defined in EN 300 392-2. At the TNSS-SAP, the served user MS can use primitives such as REQUEST, RECALL, CANCEL, LIST-CCBS, FAILED, CALL-INFORMATION-RETENTION, CALL-INFORMATION-RELEASE and USER-B-FREE. This matters because MS software needs to expose the right service primitives to the standardized part of the terminal, even if the user interface is vendor-specific.
Call information retention
Clause 4 and clause 5 define a call information retention procedure. The originating SwMI retains the TETRA Call Identifier, basic call information, call priority, addresses and the list of invoked supplementary services, and starts retention timer T4. This is the mechanism that lets the network reconnect the later CCBS call to the original failed call, so implementers must preserve the right call context for the duration of the service.
Invocation, recall and completion
Clause 5 describes the CCBS invocation and recall flow. User A MS sends a CCBS REQUEST, the originating SwMI monitors user B through the terminating SwMI, assigns a CCBSI (CCBS Identifier) and returns a REQUEST ACK. When user B becomes free, the originating SwMI sends a RECALL to User A MS, and User A MS can accept with RECALL-ACCEPTED to trigger call setup. In practice, this is the core end-to-end behavior the network and terminal must implement.
Busy handling, suspension and cancellation
Clause 5 includes the cases where User A MS is busy or user B becomes busy again. The standard defines USER-B-FREE indications, CCBS SUSPEND and RESUME procedures, user-initiated CANCEL, and network-initiated cancellation with CANCEL ACK and CANCELLED indications. This matters because CCBS can remain valid while one side is busy, but the service must also be removable cleanly when the user cancels or timers expire.
Lists of pending CCBS requests
Clause 5 defines LIST requests and LIST ACK responses. The list can report the number of pending CCBS requests, the CCBSI values, or detailed entries including called party identity and basic service. This is useful for terminals and management tools that need to show or audit outstanding callbacks rather than just waiting for a recall.
PDU and information element coding
Clause 5.2 defines the PDUs and the coding of information elements such as Basic Service Information, Called party type identifier, Calling party type identifier, Cancellation Cause, Cancellation Result, CCBS-PDU type, Reject Cause, Request Maintained, Retain Capability and TETRA Call Identifier. The standard also defines the CCBSI value ranges and special values for canceling one request or all requests. This is the part a protocol implementation must follow exactly, because interoperability depends on the same coding on both sides.
State machines, interworking and mobility
Clause 5.3 defines states for User A MS, originating SwMI, group controlling SwMI, terminating SwMI and User B. Clause 5.5 covers interworking with public ISDN, and clause 5.6 covers interactions with SS-CLIR, SS-CFU, SS-CFB, SS-CFNR, SS-LSC, SS-CAD, SS-AS, SS-PC and ANF-ISIMM. Clause 5.6.12 also defines migration-related profile information for User A MS and User B. In practice, this tells implementers how CCBS behaves across network boundaries and during mobility.
Timer control
Clause 5.7 defines timer T5 for LIST requests and says it runs between 20 seconds and 60 seconds. Other timers used by the procedures include T1, T2, T3, T4 and T6, with their behavior defined in the procedures and migration information. Timers are important because many failures, releases and retries in CCBS are driven by timer expiry rather than by explicit user action.
What terms does SIST EN 300 392-12-13 V1.2.1:2012 define?
- Additional Network Feature (ANF) - A network capability provided by the SwMI beyond the basic service, but not directly to the user.
- Switching and Management Infrastructure (SwMI) - The TETRA network equipment excluding subscriber terminals.
- Mobile Station (MS) - The subscriber terminal used by the calling or connected user.
- User A MS - The specific user MS that originated the call and requested CCBS.
- User B - The user who was initially addressed in the original call setup.
- CCBSI - The CCBS Identifier used to reference a specific CCBS invocation and its retained call information.
- recall timer - The user A response waiting timer that limits how long the network waits for User A MS to accept the CCBS recall.
- retention timer - The originating call information timer that limits how long retained call information is kept after the failed call.
Who uses SIST EN 300 392-12-13 V1.2.1:2012?
SIST EN 300 392-12-13 V1.2.1:2012 is used by TETRA network vendors, terminal vendors, system integrators and conformance engineers who implement or test CCBS behavior. It is also relevant to operators and quality teams that need to verify how a network stores call information, signals recalls, handles busy conditions and interacts with other supplementary services.
In practice, the document supports:
- MS protocol implementation
- SwMI call control and supplementary service logic
- gateway and interworking design
- protocol conformance and interoperability testing
- mobility handling for CCBS-related profile transfer

1 Scope
The present document specifies the stage 3 description of the Supplementary Service CCBS Call Completion on Busy
Subscriber for the Terrestrial Trunked Radio (TETRA).
Call Completion on Busy Subscriber allows a calling User A MS, encountering a busy destination user B, to have the
call completed when user B becomes non busy, without having to make a new call attempt.
Man-Machine Interface 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 [i.1]. The stage 1 description specifies the service
from the user's point of view. The stage 2 description identifies the functional capabilities of each SS 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
each Supplementary Service.
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 call or group call; the present document is neither
applicable to Packet Mode of Operation nor to DMO; more specifically to the following entities:
• the MS of either the calling user or the connected user during an individual call or a group call;
• the originating Switching and Management Infrastructure (SwMI) in an individual call or a group call;
• the group controlling SwMI for a group call;
• the terminating SwMI in an individual call;
• the inter-working SwMI for an individual call.

1 Scope
The present document specifies the stage 3 description of the Supplementary Service CCBS Call Completion on Busy
Subscriber for the Terrestrial Trunked Radio (TETRA).
Call Completion on Busy Subscriber allows a calling User A MS, encountering a busy destination user B, to have the
call completed when user B becomes non busy, without having to make a new call attempt.
Man-Machine Interface 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 [i.1]. The stage 1 description specifies the service
from the user's point of view. The stage 2 description identifies the functional capabilities of each SS 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
each Supplementary Service.
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 call or group call; the present document is neither
applicable to Packet Mode of Operation nor to DMO; more specifically to the following entities:
• the MS of either the calling user or the connected user during an individual call or a group call;
• the originating Switching and Management Infrastructure (SwMI) in an individual call or a group call;
• the group controlling SwMI for a group call;
• the terminating SwMI in an individual call;
• the inter-working SwMI for an individual call.

1 Scope
The present document specifies the stage 3 description of the Supplementary Service CCBS Call Completion on Busy
Subscriber for the Terrestrial Trunked Radio (TETRA).
Call Completion on Busy Subscriber allows a calling User A MS, encountering a busy destination user B, to have the
call completed when user B becomes non busy, without having to make a new call attempt.
Man-Machine Interface 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 [i.1]. The stage 1 description specifies the service
from the user's point of view. The stage 2 description identifies the functional capabilities of each SS 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
each Supplementary Service.
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 call or group call; the present document is neither
applicable to Packet Mode of Operation nor to DMO; more specifically to the following entities:
• the MS of either the calling user or the connected user during an individual call or a group call;
• the originating Switching and Management Infrastructure (SwMI) in an individual call or a group call;
• the group controlling SwMI for a group call;
• the terminating SwMI in an individual call;
• the inter-working SwMI for an individual call.
