1 Scope Word‑p. 7

The present document 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.

The present 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 the present document they mean that the indicated text is not a normative portion of the present document.

The structured functions and procedures of this protocol and the relationship with other layers and entities are described in general terms in GSM 04.07.

1.1 Scope of the Technical Specification

The procedures currently described in the present document are for supervising management over the CTS-FP/CTS-SN interface.

1.2 Application to the interface structures

The layer 3 procedures apply to the interface structures defined in GSM 04.03. GSM 04.07 gives the general description of layer 3 including procedures, messages format and error handling.

1.3 Structure of layer 3 procedures

A building block method is used to describe the layer 3 procedures.

The basic building blocks are "elementary procedures" provided by the protocol control entities.

Complete layer 3 transactions consist of specific sequences of elementary procedures. The term "structured procedure" is used for these sequences.

1.4 Test procedures

Test procedures of the CTS / Fixed Network interface signalling are described in the GSM 11.56 series.

1.5 Transmission layer

The transmission layer is out of scope of the present document. One implementation could be a V.22bis modem with an HDLC based protocol.

1.6 Overview of control procedures

1.6.1 List of procedures

The following procedures are specified in the present document:

Clause 4 specifies elementary procedures for CTS Supervising Management:
- CTS-FP initialisation procedure (subclause 4.4.1);
- CTS-FP de-initialisation procedure (subclause 4.4.5);
- CTS enrolment procedure (subclause 4.4.2);
- CTS de-enrolment procedure (subclause 4.4.6);
- CTS operation data update procedure (subclause 4.4.3);
- CTS information request procedure (subclause 4.4.4);
- CTS FP authentication procedure (subclause 4.4.7);
- CTS MS authentication procedure (subclause 4.4.8).

The elementary procedures can be combined to form structured procedures. Examples of such structured procedures are given in clause 5. This part of the Technical Specification is only provided for guidance to assist implementations.

Clause 6 specifies actions to be taken on various error conditions and also provides rules to ensure compatibility with future enhancements of the protocol.

1.7 Applicability of implementations Word‑p. 8

The applicability of procedures of the present document for the fixed part is dependent on the services and functions which are to be supported by a fixed part.

3 Definitions, abbreviations and Random values Word‑p. 12

3.1 Definitions

For the purposes of the present document, the following terms and definitions apply:

initialised Fixed Part:

Fixed Part which have been supplied with the necessary data to provide CTS service on the CTS radio interface. The CTS-FP initialisation procedure is performed at the Fixed Part installation and can be performed whenever the Fixed Part have been de-initialised.

de-initialised Fixed Part:

Fixed Part which does not contain the required data to offer CTS service. A de-initialised Fixed Part cannot offer any service.

enrolled Mobile Station:

Mobile Station is said to be enrolled on a Fixed Part if it has exchanged some data with this Fixed Part enabling attachement (e.g.in order to perform outgoing calls).

de-enrolled Mobile Station:

Mobile Station that is no more known by the Fixed Part.

CTS radio interface:

Radio interface between the Mobile Station and the Fixed Part.

3.2 Abbreviations

For the purposes of the present document, the abbreviations given in GSM 01.04 apply.

3.3 Random values

In a number of places in the present document, it is mentioned that some value must take a "random" value, in a given range, or more generally with some statistical distribution.

It is required that there is a low probability that two equipments in the same conditions (including the case of two equipments of the same type from the same manufacturer) will choose or get the same value.
