8 Message Details

3GPP52.021Network Management (NM) procedures and messages on the A-bis interfaceRelease 17TS

The formats of all messages in subclauses 8.3 through 8.11 are described each by a table format illustration with no formal text description provided because of the self-explanatory nature of the illustration.

8.1 Message Categories

This subclause defines the transport format and coding of the four Network. Management message categories sent over the Abis interface. The various message categories may be sent in either direction. In each message, the message discriminator identifies the category and is transmitted first. In a message the octets must be sent in the order shown in the description of the messages. In an octet, bit 1 must be transmitted first.

In the following subclauses, M and O denote whether information elements are mandatory or optional.

8.1.1 Formatted O&M Messages

The message format and coding of these messages are as below.

NOTE 1: The meanings and codings of the Placement Indicator are:

– only: This message is contained within one segment 1 0 0 0 0 0 0 0;

– first: The first segment of a multi-segment message 0 1 0 0 0 0 0 0;

– middle: A middle segment of a multi-segment message 0 0 1 0 0 0 0 0;

– last: The last segment of a multi-segment message 0 0 0 1 0 0 0 0.

NOTE 2: This is the sequence number of the segment in the message, modulo 256, starting with 00000000. Thus a single segment message is here coded 00000000. The number can be incremented unlimitedly being wrapped around the modulo to transport very long multi-segment messages.

NOTE 3: The Length Indicator gives the length of the O&M data field in the message segment being transported which is less than or equal to 255 octets. This length indicator should not be confused with the actual length of the message at the logical level that may go over multiple segments. This length indicator should not be confused also with attribute value length indicator described in subclause 8.2.

NOTE 4: Coding for O&M Data field is found in subclause 8.2 and the following subclauses.

NOTE 1: The channel number element shall be coded as defined for the octet of the channel number information element of specification 3GPP TS 48.058.

NOTE 2: The meanings and codings of the Repetition Indicator are:

– terminate sending of O&M TRAU frames: 0 0 0 0 0 0 0 1;

– repeat sending of O&M TRAU frames every 20 ms until a terminate order is received 0 0 0 0 0 0 1 0;

– send O&M TRAU frame once: 0 0 0 0 0 1 0 0.

NOTE 3: The TRAU O&M message is not sent when the Repetition Indicator is set to 00000001, but sending of the TRAU O&M message is mandatory otherwise. All 264 bits of the TRAU O&M frame information field are sent unchanged in the 33 octets.

NOTE 1: The Length Indicator gives the length of the Manufacturer-defined O&M data field in the message segment being transported which is less than or equal to 255 octets. See also note 3 of subclause 8.1.1

NOTE 2: The Length Indicator gives the length of the Manufacturer Identifier field which must be less than or equal to 255 octets.

NOTE 3: The Manufacturer Identifier is an octet string of maximally 255 octets. This value, to be appropriately determined by an arrangement between the operator and the manufacturer, may or may not be related to the value of the attribute Manufacturer Id (Attribute Id: 1E) listed in subclause 9.4.

Remarks: Since the Data Field of messages of this category is not subject to a GSM standardization, it should be noted that a compliance to messages of this category does not guarrantee an interoperability between different manufacturers.

8.2 Structure of Formatted O&M Messages

This subclause provides details of all the formatted O&M messages.

In every case when particular header octets provide no usable information at the receiver, they shall be coded all 1’s.

All fields in the messages are marked with M for Mandatory or O for Optional. This indicates whether the field is mandatory or optional to be contained in a message, and not whether it is mandatory or optional to be used or set for every BTS. This allows to change a single attribute without having to repeat all the attributes not to be changed.

The header fields of formatted O&M messages (see below) are always mandatory. The attributes defined for a certain message supported by the BTS implementation are mandatory to be used if not stated otherwise in an explanatory note.

The first octet of the formatted O&M messages shall identify the message types. Some messages are replied by an ACK or a NACK response. The replies shall be distinguished by different codings of the message type (the first octet of formatted O&M messages). See subclause 9.1.

ACK messages shall return all the attributes in the original message. NACK messages shall add a Nack cause field (two octets) at the end of the message.

None of the messages concerned requires all of the capacity available in a Layer 2 segment, so the NACK message will not need a second Layer 2 frame.

An ACK to a number of Load Data Segments shall consist of only the header with the ‘Load Data Segment Ack’ message type.

All attributes shall overwrite those defined in an earlier message since start-up or the last restart. Optional attributes provide new information if they have not been defined in an earlier message.

The message type and managed object identification are given in the message header as is illustrated below:

The Object Class information element shall be filled in with the correct information in accordance with the present document.

The Object Instance information element shall contain three fields:

1) the BTS Number identifies one BTS in a multi cell site;

2) the Baseband Transceiver number or the Radio Carrier number identifies which Baseband Transceiver or Radio Carrier is concerned in the message;

3) the third element identifies a radio timeslot (0-7) of the Baseband Transceiver identified by 2).

For further information see subclause 9.3.

The FORMAT field describes the structure of each information element using T(Tag), L(Length) and V(Value) coding. T is the attribute identifier. V is the actual information presented. L must be indicated if the the information element is of variable length and its prediction is not possible in the context . L shall binary-represent in a two octet space the the number of octets in the remaining part of information element. Note that this Length code differs from the "Length Indicator" described in subclause 8.1.

NOTE 1: Stop sending event reports concerning events with any of the parameter values in this attribute list. Depending on the type of event report that shall be stopped, one or some of the attributes shall be sent. The effect of multiple optional attributes in one message is that only those events that satisfy all the attributes simultaneously shall stop. The effect of repeated uses of this message with each different optional attribute is accumulative, thus, is different from the effect of putting all the optional attributes listed together at once in one message. If there occurs any inconsistency or confusion between the conditions for stopping and starting (see subclause 8.8.4), the event shall be reported instead of being stopped.
