Foreword

This Technical Basis for Regulation (TBR) has been produced by the Radio Equipment and Systems

(RES) Technical Committee of the European Telecommunications Standards Institute (ETSI).

This TBR covers the requirements for terminal (mobile) equipment for use within the European Radio

Message System (ERMES).

This TBR contains the procedures and requirements for the approval testing of ERMES terminal (mobile)

equipment which are mainly intended to be body worn.

The ERMES equipment to be approved is not intended to be physically attached to the public network.

This TBR is based on ETS 300 133-4 [2] and ETS 300 133-5 [3].

This TBR also includes a vocabulary of terms and a list of abbreviations and acronyms.

Annexes A, B and C are normative and therefore integral parts of this TBR.

1 Scope

This TBR specifies the technical characteristics to be provided by European Radio Message System

(ERMES) terminal equipment, which are mainly intended to be body worn and are capable of the

reception and decoding of signals transmitted according to the ERMES standard, as described in ETS 300

133-4 [2].

The objective of this TBR is to ensure that ERMES terminal equipment meets the essential requirements

as laid down in terms of the Directive 91/263/EEC [6], Articles 4d to 4g.

There are no specific EMC requirements included in this TBR for Article 4c of Directive 91/263/EEC [6].

The general EMC requirements for ERMES are included in ETS 300 340 [10].
2 Normative references

This TBR incorporates by dated and undated reference, provisions from other publications. These

normative references are cited at the appropriate places in the text and the publications are listed

hereafter. For dated references, subsequent amendments to or revisions of any of these publications

3 Definitions and abbreviations
3.1 Introduction

The terms, definitions and abbreviations used within this TBR are given in this clause. A definition or a

reference to a definition given in this clause is valid for all clauses of this TBR.

TBR 7: November 1994

An explanation of all the abbreviations and acronyms used in this TBR is given in alphabetical order in

subclause 3.3.

The definitions are presented in six groups. Within each group the definitions are given in a conceptual

order rather than alphabetical order.
3.2 Vocabulary
3.2.1 Administrative terms

user: A person or machine initiating an access to the operator network or receiving a message through

the operator network. User includes mobile subscribers, fixed subscribers and non-registered customers.

network operator: The administration/company which is responsible for the technical and commercial

operation of the operator network.
home operator: The network operator to which a specific user has subscribed.
3.2.2 Identity related terms

basic Radio Identity Code (RIC): The prime identity of the paging receiver allocated by the network

operator when service is initiated. It shall not be changeable without safeguards against unauthorised

changes.

Radio Identity Code (RIC): The number used by the system on the radio path to identify the receiver(s)

for which the paging signal is intended. RIC has a total length of 35 bits and consists of four parts: The

zone code (3 bits) the country code (7 bits), the operator code (3 bits) and the local address (22 bits).

operator identity: The number used by the system on the radio path to identify the home operator of a

receiver. It has a total length of 13 bits and consists of three parts, the zone code, the country code and

the operator code.

zone code: Binary representation of the zone number defined in ETS 300 133-4 [2], annex A. The zone

code consists of 3 bits.

country code: Binary representation of the country number defined in ETS 300 133-4 [2], annex A. The

country code consists of 7 bits.

operator code: The number used by the system to identify an operator within a country. It consists of 3

bits.
initial address: The 18 most significant bits of the local address.
3.2.3 Services, facilities and receiver features
group call: A call intended for two or more mobile subscribers.
3.2.4 Network related terms
ERMES system: The totality of the operator networks.

home network: The operator network with which a mobile subscriber has signed a subscription.

3.2.5 Area concepts

paging area: The area controlled by a Paging Area Controller (PAC). It is the minimum area to which a

mobile subscriber is permitted to subscribe in order to receive his paging messages.
