(Main)Digital cellular telecommunications system (Phase 2+) (GSM); GSM Cordless Telephony System (CTS), Phase 1; CTS supervising system layer 3 specification (GSM 04.57 version 7.0.3 Release 1998)
- Abstract
This Technical Specification specifies the procedures used at the CTS system interface with the supervision part i.e. the interface between the CTS-FP and the CTS-SN. Only CTS regular supervising procedures are described; FMC management is not intended to be standardised. This document does not specify the transmission layer but only the layer 3. When the notations for further study or FS or FFS are present in this ETS they mean that the indicated text is not a normative portion of this standard. The structured functions and procedures of this protocol and the relationship with other layers and entities are described in general terms in GSM04.07.

SIST EN 302 407 V7.0.3:2003 is the Slovenian standard identical to ETSI EN 302 407 V7.0.3 for Digital cellular telecommunications system (Phase 2+) (GSM), GSM Cordless Telephony System (CTS), Phase 1. It specifies the CTS supervising system layer 3 procedures on the CTS-FP/CTS-SN interface, so it is the document to use when implementing or checking supervising signalling between the Fixed Part and the Service Node. The intended users are CTS operators, fixed part and service node implementers, and test engineers working on CTS management signalling.
What does SIST EN 302 407 V7.0.3:2003 specify?
SIST EN 302 407 V7.0.3:2003 defines the layer 3 procedures for CTS supervising management over the CTS-FP/CTS-SN interface. The scope covers regular supervising procedures and states that text marked further study, FS, or FFS is not normative.
The document is organized into:
- Clause 4 - CTS supervising management procedures
- Clause 5 - examples of structured procedures, given for implementation guidance
- Clause 6 - handling of unknown, unforeseen, and erroneous protocol data
- Clause 7 - message functional definitions and contents
- Clause 8 - general message format and information element coding
- Clause 9 - system parameters, including timers and counters
Clause 7 and Clause 8 are the practical core of the specification because they define the messages and the coding that equipment has to exchange.
What are the key requirements of SIST EN 302 407 V7.0.3:2003?
SIST EN 302 407 V7.0.3:2003 uses a connection-based supervision model. All CTS supervising procedures run only when a CTS-FP/CTS-SN connection exists, and the fixed part normally starts the procedures. In practice, this means the fixed part has to establish and maintain the management connection before it can be initialised, enrolled, updated, or authenticated.
Connection and state handling
- Clause 4.2 and 4.3 define CTS-SPM procedures and states on both the Fixed Part and Service Node sides.
- Only one CTS-SPM connection can be active at a time on the Fixed Part side.
- An active CTS-SPM connection can coexist with active CTS-RR and CTS-MM connections on the CTS radio interface.
This matters because implementers have to manage supervisory signalling independently from radio interface signalling, but without creating parallel CTS-SPM connections.
Main management procedures
- Clause 4.4.1 defines CTS-FP initialisation: the Fixed Part sends a request with its identity and classmark, and the Service Node answers with the radio parameters needed to operate.
- Clause 4.4.2 defines CTS enrolment: after local enrolment, the Fixed Part can request Service Node approval for a Mobile Station using the Fixed Part identity, Mobile Station identity, and a Cell Identity List.
- Clause 4.4.3 defines operation data update: the Service Node provides Radio Frequency control parameters, Radio Link control parameters, a Generic Frequency List, and timing data such as Tval, Trecal, and Tapplic.
- Clause 4.4.4 defines information data exchange, where the Service Node requests data used by the Fixed Part and the Fixed Part returns it.
- Clause 4.4.5 and 4.4.6 define de-initialisation and de-enrolment procedures in both directions.
- Clause 4.4.7 and 4.4.8 define Fixed Part authentication and Mobile Station authentication.
These procedures are the operational backbone of CTS management, covering setup, subscriber attachment, operational parameter delivery, and security checks.
Message and coding rules
- Clause 7 defines each message’s direction, significance, and content tables.
- Clause 8 defines the Protocol Discriminator, the skip indicator, message types, and the coding of information elements.
- The skip indicator for CTS Radio Resource management and CTS Mobility Management messages is fixed to 1111, so receivers can distinguish CTS messages from GSM messages.
- Clause 8 also defines the information elements used for identities, classmarks, radio control, frequency lists, and timers.
These rules matter because interoperability depends on exact message formats and on consistent coding of identities, timers, and control parameters.
What terms does SIST EN 302 407 V7.0.3:2003 define?
- CTS supervising management protocol (CTS-SPM) - the control protocol used for CTS supervising management between the Fixed Part and the Service Node.
- initialised Fixed Part - a Fixed Part that has been given the data needed to provide CTS service on the CTS radio interface.
- de-initialised Fixed Part - a Fixed Part that lacks the required data to offer CTS service.
- enrolled Mobile Station - a Mobile Station that has exchanged data with a Fixed Part so that attachment is enabled.
- de-enrolled Mobile Station - a Mobile Station that is no longer known by the Fixed Part.
- CTS radio interface - the radio interface between the Mobile Station and the Fixed Part.
Who uses SIST EN 302 407 V7.0.3:2003?
SIST EN 302 407 V7.0.3:2003 is used by CTS operators who manage subscriber enrolment, de-enrolment, authentication, and operation data. It is also used by equipment designers for the Fixed Part and Service Node, because they must implement the CTS-FP/CTS-SN signalling procedures and message coding.
Test laboratories use it together with the CTS/Fixed Network interface signalling test specifications to verify that implementations exchange the right messages and react correctly to accept, reject, and timer-based events.
Which standards are used with SIST EN 302 407 V7.0.3:2003?
- GSM04.03 - defines the interface structures to which the layer 3 procedures apply.
- GSM04.07 - gives the general layer 3 rules, including procedure structure, message formats, and error handling.
- GSM04.08 - is referenced for handling unknown, unforeseen, and erroneous protocol data.
- GSM04.56 - gives the CTS radio interface layer 3 specification and the local enrolment procedure.
- GSM03.56 - defines the CTS service description and the cases where authentication procedures are used.
- GSM03.20 Annex E - is referenced for the authentication response calculation.
- GSM11.56 series - gives the CTS/Fixed Network interface signalling test procedures.
- GSM01.04 - provides the abbreviations and acronyms used in the document.
What does the SIST EN 302 407 V7.0.3:2003 document contain?
SIST EN 302 407 V7.0.3:2003 contains procedure descriptions, message definitions, coding rules, and supporting examples. Clause 5 provides sequence diagrams for the structured procedures, which helps implementers understand the order of exchanges.
Clause 7 contains the message tables for initialisation, de-initialisation, enrolment, de-enrolment, operation data, information data, FP authentication, MS authentication, and SN signing mode command. Clause 8 contains coding diagrams and field definitions for identities, control parameters, frequency lists, and timer-related information elements.
Clause 9 lists system parameters in the form of timers and counters for radio resource management on the SN side and the CTS-FP side.
