2. GENERAL PRESENTATION

2.1. PRELIMINARIESThe message dictionary details the non-transparent messages handled by the ALCATEL BSS on the Air interface for GSM phase 2.

Each message is described in the same way :

- A general overview,- A detailed description of the Information Elements,- A bit description.

The messages dictionary includes also in this part :

- A summary of all the messages described into the dictionary,

- A cross reference of all the 04.08 Information Elements used by the messages described in this dictionary. This allows to find all the 04.08 messages in which one Information Element appears.

2.2. MESSAGES PRESENTATION

2.2.1. INTRODUCTIONAll the messages are organised alphabetically under the relevant interface (SMSCB messages are gathered in a dedicated section. Three parts are given for each messages :

- a general overview :

It is a general description of the message including the Information Elements list, the maximum and minimum lengths in octets, the normal and abnormal following events.

- A detailed description of the Information Elements :

It is mainly the use of the Information Element within the BSS entities.

- A Bit Description :

It is a bit presentation of the message as it is received or transmitted over the involved interfaces.

Note : Within this document, DCS 1900 is assimilated to DCS 1800 operation except where explicitly specified. In information element list given at the beginning of each message, "DCS 1800 only" should be understood as "DCS 1800 and DCS 1900 only".

5 DESCRIPTION OF THE HEADER ON THE AIR INTERFACE.

This section is not relevant to SMSCB messages.

The header on the Air interface is called header and is composed of three parameters :

- Protocol discriminator.- Transaction identifier or skip indicator.- Message type.

GENERAL DESCRIPTION

8 7 6 5 4 3 2 1Transaction identifier

or skip indicatorProtocol Discriminator

0 N(SD) Message type

The skip indicator and send sequence number N(SD) are not checked by the BSS.

Ed 04 AIR INTERFACE INTRODUCTION3BK 11202 0074 DSZZA


PARAMETER NAME : PROTOCOL DISCRIMINATOR

DEFINITIONThe purpose of the protocol discriminator is to distinguish between messages belonging to the following procedures.

- call control - mobility management - radio resources management - other signalling procedures.

The protocol discriminator is the first part of every message and occupies the first four bits of the first octet in a message.

BIT DESCRIPTION

<---------------->PD

All others values are reserved.



PARAMETER NAME : TRANSACTION IDENTIFIER/SKIP INDICATOR

DEFINITION : The purpose of transaction identifier (TI) is to distinguish multiple parallel activities (transactions) within one mobile station.

The TI flag identifies who allocates the TI value for this transaction, so the TI flag resolves simultaneous attempts to allocate the same TI value.

BIT DESCRIPTION

TI Flag :

0 The message is sent from the side that originates the TI.1 The message is sent to the side that originates the TI.

TI value :

From 0 to 6

The value 7 is reserved for future extension.

The transaction identifier for Mobility Management and Radio resources messages used the predefined value 0.

NS(S) not used for Radio Resource messages but used for the sequencing of the Mobility Management and Connection Management messages to avoid duplication of messages.

This parameter is deduced from the A interface Channel type Info element.

Data rates received on the A interface which are lower than 2.4 kbit/s are mapped onto the "data 3.6 kbit/s radio interface rate" in this element (value 0001 0011 or 0001 0111), depending whether full or half rate is requested on the A interface.



PARAMETER NAME : FREQUENCY CHANNEL SEQUENCE TYPE : C

DEFINITIONTo provide the absolute radio frequency channel numbers used in the Mobile Hopping Sequence. This parameter will be always used instead of Mobile Allocation, and cell channel description elements (GSM900).

10 inc skip of ARFCN 15 inc skip of ARFCN 16

Bit 8 of octet 2 is spare.


Lowest ARFCN : Value x : 1 to 124this field is coded as the binary representation of the lowest absolute RF channel, appearing in the sequence of channels used in frequency hopping.

inc skip of ARFCN n :this field is coded as the binary representation of the Increment of preceding absolute RF channel number appearing in the sequence of channels used in the frequency hopping n = 1,...,16.

Range : 0 to 15

The value 0 means a increment of 15, but the concerned channel is not used and the next field (i.e. Increment skip ARFCN N+1) if present must be added to the increment to determine the next absolute RF channel number.


Same as Mobile Allocation and cell channel description. Stored and updated during system reconfiguration.



PARAMETER NAME : CIPHER MODE SETTING TYPE : O

DEFINITIONThe purpose of the cipher mode setting information element is to indicate whether stream ciphering shall be started or not. When ciphering is started, it indicates the algorithm to be used (except for GSM phase 1 MS).
