2 GENERAL PRESENTATION
2.1 Preliminaries
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 Information Elements. This allows finding all the messages in whichone Information Element appears.
2.2 Messages presentation
2.2.1 Introduction
All the messages are organised alphabetically under the relevant interface (SMSCB and GPRSmessages are gathered each 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 maximumand 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.
2.2.2 The general overview
It is the first page for each message. It includes:
NAME field:The name of the message.
INTERFACE field:The list of three Interfaces
CHANNEL/USAGE field:According to the involved interface, it is the radio channel definition or the fact that the message istransparent or not for the BTS. When the box is empty, the message is not used on this interface.
3GPP-REF. field:It is the reference to a 3GPP technical specification.
FUNCTION field:It is the description of the function of the message. This is extracted from the 3GPP technical
specifications.

DIRECTION field:It is the direction of the message from one entity of the BSS or MS to another one.
INFORMATION ELEMENT LIST field:It is the list of all the Information Elements. For each Information Element the following information isgiven:
- Mandatory or Optional,
- Fixed or Variable length,
- The length in bytes,
- Some short comments.For a full description of the use of 'M', 'C', 'L', 'O' and 'V', refer to 3GPP TS 04.07. These rules are alsoused for SMSCB IEs although they are not defined in 3GPP TS.
IMPLEMENTATION MAXIMUM LENGTH field:It is the total of all used information elements, mandatory or optional. When the length is fixed for allparameters, a unique value is given. When not, a range is given ("minimum length" - "maximumlength")
FOLLOWING EVENT field:It is the description of following events (for specific procedure) for the normal and abnormal cases.
TIMER field:It is the name of the Timers (started or stopped) associated with the message.
SPECIFICATION DOC. REF. field:It is the reference of relevant ALCATEL document.
2.3 The information element description
One page (or more) per Information Element (The classification of the following pages respects the
order given by 3GPP TS).On the Radio Interface, if the Information element is mandatory, the Information element identifier (IEI)is not present (it is marked with a star). If the length is fixed the length is not present.For each Information Element:
PARAMETER NAME field
TYPE field:This field is used to give the Mandatory or Optional information.Note: In the 3GPP TS 44.018, this field has been split into two fields designated presence and
Format. For simplicity the designation TYPE is retained in this document.
DEFINITION field:
It is an extract of 3GPP TSs. giving the usage of the Information Element.
BIT DESCRIPTION field:It is a bit description of the element with all the needed information, including the sub parameter definition.
SUB-PARAMETER DEFINITION field:It is a description (if needed) of all the sub parameters defined in the bit description.
PARAMETER ORIGIN - ACTION ON PARAMETER field:It is a description of the action to be performed when receiving or transmitting the message.

5 DESCRIPTION OF THE HEADER ON THE RADIO INTERFACE
This section is not relevant to SMSCB nor GPRS messages.
5.1 GENERAL DESCRIPTION FOR STANDARD L3 MESSAGE
The header on the radio interface is called header and is composed of three parameters:
• Protocol discriminator.
• Transaction identifier or skip indicator.
• Message type.
8 7 6 5 4 3 2 1
Transaction identifier or skip indicator
Protocol Discriminator
Message type I.E.
5.1.1 PROTOCOL DISCRIMINATOR
DEFINITIONThe purpose of the protocol discriminator is to distinguish between messages belonging to thefollowing 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 firstoctet in a message.

5.1.2 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 resolvessimultaneous attempts to allocate the same TI value.
BIT DESCRIPTION
8 7 6 5 4 3 2 1
TIflag
TI value
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 6The value 7 is reserved for future extension.
The transaction identifier for Mobility Management and Radio Resources messages use thepredefined value 0 ( it is the skip indicator in this case ).
5.1.3 MESSAGE TYPE
The message type IE and its use are defined in 3GPP TS 24.007.
The bit 7 (and possibly bit 8, see below), N(SD), is reserved for the sequencing of theMobility Management and Connection Management messages to avoid duplication of messages.
The skip indicator and send sequence number N(SD) are not checked by the BSS.
Note: Case of BCCH and AGCH/PCH messages
The messages are structured as standard L3 messages plus one octet in front, the L2 pseudo lengthoctet, and a rest octet part at the end.
5.1.3.1 Coding of message type IE when accessing Release 98 and older networks
Message Type I.E. of MM, CC, SS, GCC, BCC and LCS messages is coded as follows when
accessing Release 98 and older networks :
8 7 6 5 4 3 2 1
0 N(SD) Message type
Message Type I.E. of messages other than MM, CC, SS, GCC, BCC and LCS is coded as follows when accessing Release 98 and older networks :

5.2 GENERAL DESCRIPTION FOR NON STANDARD L3 MESSAGE
In some protocols, the structure of part or all of the messages might not always follow the standard L3message structure. As a design rule, this should be consistent for a given protocol, direction and lower layer SAP.
5.2.1 Messages using the short header format
The messages are structured either as standard L3 messages, or in the so-called short header format. The value of the 8
thbit (bit 1 of octet 1) of the link layer PDU distinguishes the two cases. In
the case of the short header, the L3 message is the same bit string as the link layer PDU, and has a
fixed length. The following description includes the 2-bit link layer header.
5.2.1.1 The first octet
Bits 1 and 2 are the link layer header. Bit 2 of octet 1 is set to "0", and bit 1 is reserved for the linklayer.A protocol discriminator is the first part of the message (starting bit 8 of octet 1). The protocoldiscriminator field may have different lengths. The following protocol discriminator is defined:
• 0 RR.
All additional PD defined for this structure shall start by 1. The reception of a message with bit 8 of octet 1 set to 1 when expecting a message structured as defined by this clause shall be diagnosed asan unknown PD, and the message ignored.As a design rule, a message type field should follow the PD, and of a length such that the PD and themessage type fit in the 6 first bits of the message.
5.2.1.2 The rest of the message
The rest of the structure is not more constrained.
5.2.1.3 MESSAGE TYPE
The message type IE and its use are defined in 3GPP TS 24.007.

SUB PARAMETER DEFINITION
Bits 5 and 6 are spare bits in octet 3.
FORMAT-ID : Format identifier.
F0 : Frequency 0 indicator. Coded 0 if ARFCN 0 is not a member of the set. Coded 1 if ARFCN 0 is a member of the set.
ORIG-ARFCN : This field encodes the ARFCN of one frequency belonging to the set. This value isalso used as the origin of the bit map to generate all the other frequencies.
RRFCN N : Relative Radio Frequency Channel Number N.- For an RF channel with ARFCN = (ORIG-ARFCN + N) mod 1024 belonging to the set,
then RRFCN N bit is coded as '1'.- For an RF channel with ARFCN = (ORIG-ARFCN + N) mod 1024 not belonging to the set,
then RRFCN N bit is coded as '0'.
W : Each non null W(k) allows to compute, together with some previous W(i) the ARFCNF(k) of a frequency in the set (see 3GPP TS 44.01844.018 for computation formulas).

SPECIFDOC. REF.
Call release (ref. [5])
(1) Sent to phase 2 MS, only during location updating procedure.
(2) Only sent to the MS which supports the GPRS services.
(3) There is only one Use Case in which the BTS sends Channel Release message with Group
Channel Description OIE and Cell Channel Description OIE:
“If a MS VGCS originator/talker performs an intercell handover towards a non hopping channel,
and if in the target cell the corresponding group call channel is a hopping one. When the talker
stops talking, if the BTS sends Channel Release message with Group Channel Description OIE
but without Cell Channel Description OIE, the former talker cannot understand this message”.
See “reason for change” of 3GPP CR 44.018/301r2.In case of Notification Response procedure, the BTS sends Channel Release message withGroup Channel Description OIE but without the Cell Channel Description OIE.

RXLEV carrier 'N': This field is coded as the binary representation of a value M. M correspondsaccording to the mapping defined in TS. 3GPP TS 05.08 to the receivedsignal strength on carrier N. N is the index to the frequency in the sorted list of frequencies defined in the EXTENDED MEASUREMENT ORDER message.
The list is sorted in increasing order of ARFCN, except that ARFCN 0, if included in the EXTENDED MEASUREMENT ORDER, is put in the lastposition of the sorted list. If the EXTENDED MEASUREMENT ORDERcontains more than 21 carriers, only the signal strength of the carriers 0-20shall be measured and reported.

(1) Used in the two following cases: i) Used for Phase 2 biband MS when the assigned channel ishopping in the P-GSM band if it is the shortest way to encode the hopping frequencies or ii) usedfor any MS when the assigned channel is hopping in the E-GSM (and not P-GSM), GSM850,DCS1800 or DCS1900 band if it is the shortest way to encode the hopping frequencies.
(2) Internal handover: Sent only if cipher algorithm is changed in a phase 2 MS.External handover:-
Phase 1 MSs: never sent- Phase 2 MSs:
- if chosen encryption is the same as the one used on the old channel (*): not sent- Otherwise (chosen encryption is different or not known) : sent.(*)Note: This information is given in the OIE “chosen encryption algorithm (serving)” sent by theMSC in HO_REQUEST.
(3) Always included, although optional.
(4) Phase 2 MS: Only included in case of synchronous handover,Phase 1 MS: Always included as required in GSM ETR 09.94.

SUB PARAMETER DEFINITION
MA length depends on the relative frequency span of the frequencies in the cell allocation frequencylist.
MA Ci:Mobile Allocation RF Channel i - the RF channels represented in the MA C i bit fields are those whichin the "Cell Channel Description" information element are coded with "1" in the CA ARFCN N bit fields.
MA Ci = CA ARFCN N(i) i = 1,2...NF
(NF = Number of Frequencies in the CA frequency list).
For a RF channel belonging to the Mobile Allocation the MA C i bit is coded with a "1", for a RFchannel not belonging to the Mobile Allocation, the MA C i bit is coded with a "0".If NF mod 8 <> 0then bits NF to 8n in octet 3 must be coded with a "0" in each.
PARAMETER ORIGIN - ACTION ON PARAMETER
The parameter is transparent for the BTS when received from the BSC.
At the BSC site the following actions have to be performed
Mobile Allocation Stored and Updated during system reconfiguration.

NR_OF_FDD_CELLS (5 bit field)This field defines the number of FDD_CELL_INFORMATION parameters.Set from O&M parameter.
FDD_CELL_INFORMATION Field (p bit field)This field allows to compute a set of 10-bit-long FDD_CELL_INFORMATIONparameters, re-using the Range 1024 format compression algorithm. Theconsecutive parameters of this field are concatenated, starting with w1, and
then w2, w3…The total number of bits p of this field depends on the value of the parameter NR_OF_FDD_CELLS = n, as follows:
n p n p n p n p0 0 5 44 10 81 15 1161 10 6 52 11 88 16 1222 19 7 60 12 95 17-31 03 28 8 67 13 1024 36 9 74 14 109
Note: in B9, n = 1..8.For each (10-bit-long) decoded Parameter, bits 1-9 are the Scrambling Codeand bit 10 is the corresponding Diversity Parameter.Bit 10 is the most significant bit.

FORMAT-ID : Format identifier.
F0 : Frequency 0 indicator. Coded 0 if ARFCN 0 is not a member of the set. Coded 1 if ARFCN 0 is a member of the set.
ORIG-ARFCN : This field encodes the ARFCN of one frequency belonging to the set. This value isalso used as the origin of the bit map to generate all the other frequencies.
RRFCN N : Relative radio frequency channel number N- For an RF channel with ARFCN = (ORIG-ARFCN + N) mod 1024 belonging to the set,
then RRFCN N bit is coded as '1'.-
For an RF channel with ARFCN = (ORIG-ARFCN + N) mod 1024 not belonging to the set,then RRFCN N bit is coded as '0'.
W : Each non null W(k) allows to compute, together with some previous W(i) the ARFCNF(k) of a frequency in the set (see 3GPP TS 44.018 for computation formulas).

SUB PARAMETER DEFINITION
POWER OFFSET : Not supported ( POI set to "L" ).
2TI : Set by O&M.
ECSC : Early Sending is explicitly accepted ( always set to "H" ).
WHERE : the WHERE field is not contained, as SYSTEM INFORMATION 9 is not
broadcast.
PI, CELL_RESELECT_PARAM_IND
0: C2 parameters not present.1: C2 parameters are present.
PI is used by the mobile station to determine if the C2 parameters which are, CBQ,CELL_RESELECT_OFFSET, TEMPORARY_OFFSET and PENALTY_TIME are beingbroadcast by the network in this message.
CBQ, CELL_BAR_QUALIFY
CELL_BAR_QUALIFY is used by the network to control mobile station cell selection andreselection. The use and coding of this parameter is defined in 3GPP TS 05.08.
CELL_RESELECT_OFFSET
CELL_RESELECT_OFFSET is coded as the binary representation of the"CELL_RESELECT_OFFSET" in 3GPP TS 05.08. It is a value used by the mobile station toapply a positive or negative offset to the value of C2 as defined in 3GPP TS 03.22 and 3GPPTS 05.08.
TEMPORARY_OFFSET
The TEMPORARY_OFFSET field is coded as the binary representation of the"TEMPORARY_OFFSET" in 3GPP TS 05.08. It is used by the mobile station as part of itscalculation of C2 for the cell reselection process as described in 3GPP TS 05.08. It is used to
apply a negative offset to C2 for the duration of PENALTY_TIME.
PENALTY_TIME
The PENALTY_TIME is coded as the binary representation of the "PENALTY_TIME" in 3GPPTS 05.08. It defines the length of time for which TEMPORARY_OFFSET is active. The usageof PENALTY_TIME is described in 3GPP TS 03.22 and 3GPP TS 05.08.
GPRS Indicator: The GPRS Indicator contains RA Colour and SI13_Position fields. If the GPRSIndicator is contained in the SI 3 REST OCTETS, it indicates that GPRS is supported in thecell:
RA Colour : Routing area color of the cell set by O&M
SI13_Position :0 SYSTEM INFORMATION TYPE 13 message is sent on BCCH Norm
1 SYSTEM INFORMATION TYPE 13 message is sent on BCCH Ext
3G ECSR: 3G Early Classmark Sending Restriction: always set to either ‘L’: (Neither UTRAN nor cdma2000 classmark change message shall be sent with the Early classmark sending) or ‘H’(The sending of UTRAN and CDMA2000 Classmark Sending messages is controlled bythe Early Classmark Sending Control parameter) according to the O&M parameter EN_3G_HO.
SI2quater Indicator : The SI2quater Indicator contains the SI2quater_Position field. It is always setto “Low” (i.e. SI2quater Indicator field is not present), indicating that SI 2quater message is notbroadcast.

The number of SI10 instances depend on the number of BCCH frequencies described in SI5/5bis/5ter and the number of cell expressed on term of pair (BCCH frequency, BSCI/BCC).
<Example>
• The following list of neighbour cell frequencies (BCCH frequencies) have been sent onSACCH of voice group call channels via SI5/5bis/5ter:
f(0), f(1), f(2), f(3), f(4), f(5), f(6), f(7), f(8), f(9), f(10), f(11), f(12), f(13), f(14), f(15).

Assuming that the list of neighbour cell frequencies are in the following order determined bythe mobile station:
a(1): f(0); a(2): f(1); a(3): f(2); a(4): f(3); a(5): f(4); a(6): f(5); a(7): f(6); a(8): f(7); a(9): f(8); a(10): f(9); a(11): f(10); a(12): f(11); a(13): f(12); a(14): f(13); a(15): f(14); a(16): f(15).
• Assuming that the subset of surrounding cell list contains 14 cells and the correspondingpair (BCCH frequency, BSCI/BCC) are the following:
cell1=[f(0), bsic_0];cell2=[f(1), bcc_0];cell3=[f[1], bcc_1];cell4=[f(5), bcc_1];cell5=[f(6), bcc_1];cell6=[f(6), bcc_2];cell7=[f(6), bcc_3];

6.55.2 BCCH_CHANGE_MARK
TYPE: M
DEFINITION
This field indicates the status of the information on BCCH. The value of this field may be changed
when information on BCCH is changed, see 3GPP TS 44.060.
BIT DESCRIPTION
SUB PARAMETER DEFINITION
PARAMETER ORIGIN - ACTION ON PARAMETER
The value of this field shall be increased by 1 each time the information content is changed on BCCH,but shall not be incremented when SI 13 only is modified.
6.55.3 SI_CHANGE_FIELD
TYPE: M
DEFINITION
SI_CHANGE_FIELD value indicates which SI among type 1, 2, 3, 4, 7, 8 (, 9) has changed at the lastBCCH_CHANGE_MARK indication. Range 0 to 15:
BIT DESCRIPTION
0 Update of unspecified SI message or SI messages: this is used in case of update of several different SI types (e.g. SI 16 & SI 17 modifications when LSA_IDs areconfigured in the cell)
1 Update of SI 1 message2 Update of SI 2, SI 2bis or SI 2ter message3 Update of SI 3, SI 4, SI 7 or SI 8 message4 Update of SI 9 message (not used, since SI 9 is not supported)5 Update of SI18 or SI20 message (not used, since SI 18 and SI 20 are not supported)6 Update of SI19 message(not used, since SI 19 is not supported)
All other values shall be interpreted as 'update of unknown SI message type'.
SUB PARAMETER DEFINITION
PARAMETER ORIGIN - ACTION ON PARAMETER
Upon changes of the contents of the RACH Control Parameters information element alone, it would besufficient that the SI_CHANGE_FIELD parameter indicates only one of the SI message containing theRACH Control Parameters (e.g. SI 1). But, in practice, the BSC only increments theBCCH_CHANGE_MARK value and does not update the SI_CHANGE_FIELD parameter. So the MS will get the last updated SI message(s) once more.
When there is no PBCCH configured in the cell, the BSC shall notify the MFS of anyBCCH_CHANGE_MARK modification with the new SI_CHANGE_FIELD value.

6.55.5 GPRS MOBILE ALLOCATION
TYPE: O
DEFINITION
This information element is the representation of the GPRS mobile allocation provided in SI13
message. It is identified by MA_NUMBER = 14 when referenced from a packet assignment message.The GPRS Mobile Allocation information element defines a set of radio frequency channels and ahopping sequence number (HSN), which may be allocated to a mobile station to define its channelconfiguration.
There are two alternative ways to encode the GPRS mobile allocation, using the MA_BITMAP or theARFCN index list. The MA_BITMAP is used by the Alcatel BSS.
BIT DESCRIPTION
< GPRS Mobile Allocation IE > ::=< HSN : bit (6) >{ 0 | 1 < RFL number list : < RFL number list struct > > }{ 0 < MA_LENGTH : bit (6) >

This field is the binary representation of the hopping sequence number, Range: 0 to 63.
RFL number list (construction)
This construction is a list specifying the referenced set of reference frequency lists for thisinformation element. Note that the Alcatel BSS does not use this construction.
MA_BITMAP (variable length, 1 to 64 bit, field)
This field is a bitmap representing the radio frequency channels belonging to the GPRSmobile allocation. The number of bit positions in MA_BITMAP shall equal NF (NF: Number of Frequencies). The first bit position in MA_BITMAP corresponds to ARFCN_INDEX = NF-1, thelast position corresponds to ARFCN_INDEX = 0. Each bit position is coded:
0 the corresponding radio frequency channel does not belong to the GPRSmobile allocation;
1 the corresponding radio frequency channel belongs to the GPRS mobileallocation.
