Overview

SIST ETS 300 392-10-13 E1:2003 addresses the supplementary service known as "Call Completion to Busy Subscriber" (CCBS) within Terrestrial Trunked Radio (TETRA) networks. As part of the broader TETRA standard suite, it defines the principles and expected user experience when a calling party encounters a busy destination and wishes the call to be automatically completed once the destination becomes available. This standard is vital for digital trunked radio systems-widely used in mission-critical communication sectors across Europe-ensuring efficient use of network resources and improving user satisfaction.

Key Topics

• Call Completion to Busy Subscriber (CCBS):
  The core supplementary service allows a calling user to have their call automatically retried and completed when the busy user becomes available, without manually redialing.

• Switching and Management Infrastructure (SwMI):
  All core references to "Private Telephone Network (PTN)" are replaced with SwMI, highlighting the switch-centric architecture in TETRA V+D services.

• Service Activation and Operation:

  • CCBS can be provided by pre-arrangement or as a general service.
  • The service is always active when provided, with deactivation possible upon request.
  • When a call attempt fails due to a busy subscriber, the SwMI retains the caller's request for a set period, monitors the busy party, and notifies the caller once the called party is reachable.

• Interaction With Other Supplementary Services:
  Detailed interactions, or lack thereof, are specified between CCBS and more than 30 other TETRA supplementary services, ensuring predictable network behavior.

• User Experience Considerations:
  The standard focuses on the procedures and expected service behavior, leaving out human interface specifics, which are implementation-dependent.

Applications

The CCBS supplementary service as specified in SIST ETS 300 392-10-13 E1:2003 is crucial in environments where communication continuity and quick call completion are essential, particularly when network load and user availability fluctuate. Key application areas include:

• Public Safety and Emergency Services:
  Ensures urgent calls are not lost when a recipient is temporarily busy, supporting rapid re-connection once the recipient becomes available.

• Transportation and Utilities:
  Enables efficient communication among dispatchers and field personnel, reducing downtime caused by busy signals.

• Industrial and Corporate Radio Networks:
  Boosts productivity by minimizing failed call attempts, allowing users to focus on operational tasks rather than re-attempting calls.

• Any Mission-Critical Communications:
  Improves availability and reliability for organizations depending on TETRA networks for daily operations, directly supporting operational efficiency.

Related Standards

SIST ETS 300 392-10-13 E1:2003 is part of a comprehensive suite governing TETRA networks and supplementary services. Key related standards include:

• SIST ETS 300 392-10 (Parts 1–12):
  Addressing general network design, air interfaces, gateways, security, performance objectives, and various supplementary services.

• ETSI ECMA 185:
  Forms the core reference for supplementary service descriptions and operational models, with SIST ETS 300 392-10-13 clarifying the TETRA-specific requirements and deviations.

• TETRA 03.60 to 03.85:
  Cover other TETRA services and operational specifications, ensuring interoperability and harmonized service behavior across Europe.

• Other TETRA Supplementary Service Standards:
  Such as call forwarding, call waiting, and call transfer (where applicable in TETRA V+D).

By aligning with SIST ETS 300 392-10-13 E1:2003, organizations deploying Terrestrial Trunked Radio networks can provide enhanced service availability, better resource management, and a consistent communication experience across European public safety, transportation, and industrial sectors.

1 Scope
This is a delta document detailing the deviations of the Trans-European Trunked RAdio (TETRA) Call
Completion to Busy Subscriber (CCBS) supplementary service from the Standard ECMA 185 [2] stage
1 descriptions. Stage 1 is an overall service description from the users point of view but does not deal
with the details of the human interface itself.
This European Telecommunication Standard (ETS) specifies the service description of the
supplementary service and the procedures to be expected with successful and unsuccessful
outcomes. In addition this ETS specifies the interactions with other TETRA supplementary services
and inter-working considerations.
Charging principles are outside the scope of this ETS.
The CCBS supplementary service enables a calling user A, encountering a busy destination user B, to
have the call completed when user B becomes not busy, without having to make a new call attempt.
