9 Elements for M2AP Communication

36.4433GPPEvolved Universal Terrestrial Radio Access Network (E-UTRAN)M2 Application Protocol (M2AP)Release 17TS

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

9.1 Message Functional Definition and Content

9.1.1 General

Sub clauses 9.1 and 9.2 describe the structure of the messages and information elements required for the M2AP protocol in tabular format. Sub clause 9.3 provides the corresponding ASN.1 definition.

The following attributes are used for the tabular description of the messages and information elements: Presence, Range Criticality and Assigned Criticality.

9.1.1 Message Contents

9.1.1.1 Presence

All information elements in the message descriptions below are marked mandatory, optional or conditional according to table 4.

Table 4. Meaning of abbreviations used in M2AP messages

Abbreviation	Meaning
M	Ies marked as Mandatory (M) shall always be included in the message.
O	Ies marked as Optional (O) may or may not be included in the message.
C	Ies marked as Conditional (C) shall be included in a message only if the condition is satisfied. Otherwise the IE shall not be included.

9.1.1.2 Criticality

Each Information Element or Group of Information Elements may have criticality information applied to it.
Following cases are possible:

Table 5. Meaning of content within “Criticality” column

Abbreviation	Meaning
–	No criticality information is applied explicitly.
YES	Criticality information is applied. This is usable only for non-repeatable Ies.
GLOBAL	The IE and all its repetitions together have one common criticality information. This is usable only for repeatable Ies.
EACH	Each repetition of the IE has its own criticality information. It is not allowed to assign different criticality values to the repetitions. This is usable only for repeatable Ies.

9.1.1.3 Range

The Range column indicates the allowed number of copies of repetitive Ies/IE groups.

9.1.1.4 Assigned Criticality

This column provides the actual criticality information as defined in subclause 10.3.2 in TS 36.413 [4], if applicable.

The meaning of the different cause values is described in the following table. In general, “not supported” cause values indicate that the related capability is missing. On the other hand, “not available” cause values indicate that the related capability is present, but insufficient resources were available to perform the requested action.

Radio Network Layer cause	Meaning
Unknown or already allocated MCE MBMS M2AP ID	The action failed because the MCE MBMS M2AP ID is either unknown, or (for a first message received at the eNB) is known and already allocated to an existing MBMS service related context.
Unknown or already allocated eNB MBMS M2AP ID	The action failed because the eNB MBMS M2AP ID is either unknown, or (for a first message received at the MCE) is known and already allocated to an existing context.
Unknown or inconsistent pair of MBMS M2AP IDs	The action failed because both MBMS M2AP IDs are unknown, or are known but do not define a single MBMS context.
Radio resources not available	No requested radio resources are available
Interaction with other procedure	The action is due to an ongoing interaction with another procedure
Unspecified	Sent for radio network layer cause when none of the specified cause values applies
Invalid QoS combination	The action was failed because of invalid QoS combination.
Not supported QCI Value	The E-RAB setup failed because the requested QCI is not supported.

Transport Layer cause	Meaning
Transport Resource Unavailable	The required transport resources are not available.
Unspecified	Sent for transport network layer cause when none of the specified cause values applies.

NAS cause	Meaning
Unspecified	Sent for NAS cause when none of the specified cause values applies.

Protocol cause	Meaning
Transfer Syntax Error	The received message included a transfer syntax error.
Abstract Syntax Error (Reject)	The received message included an abstract syntax error and the concerning criticality indicated “reject”.
Abstract Syntax Error (Ignore And Notify)	The received message included an abstract syntax error and the concerning criticality indicated “ignore and notify”.
Message Not Compatible With Receiver State	The received message was not compatible with the receiver state.
Semantic Error	The received message included a semantic error.
Abstract Syntax Error (Falsely Constructed Message)	The received message contained Ies or IE groups in wrong order or with too many occurrences.
Unspecified	Sent for protocol cause when none of the specified cause values applies.

Miscellaneous cause	Meaning
Control Processing Overload	Control processing overload.
Hardware Failure	Action related to hardware failure
O&M Intervention	The action is due to O&M intervention.
Unspecified	Sent when none of the above cause values applies and the cause is not related to any of the categories Radio Network Layer, Transport Network Layer, NAS or Protocol.

9.3 Message and Information Element Abstract Syntax (with ASN.1)

9.3.1 General

M2AP ASN.1 definition conforms with ITU-T Rec. X.691 [5] and ITU-T Rec. X.680 [6].

Sub clause 9.3 presents the Abstract Syntax of the M2AP protocol with ASN.1. In case there is contradiction between the ASN.1 definition in this sub clause and the tabular format in sub clause 9.1 and 9.2, the ASN.1 shall take precedence, except for the definition of conditions for the presence of conditional elements, in which the tabular format shall take precedence.

The ASN.1 definition specifies the structure and content of M2AP messages. M2AP messages can contain any Ies specified in the object set definitions for that message without the order or number of occurrence being restricted by ASN.1. However, for this version of the standard, a sending entity shall construct an M2AP message according to the PDU definitions module and with the following additional rules (Note that in the following IE means an IE in the object set with an explicit id. If one IE needed to appear more than once in one object set, then the different occurrences have different IE ids):

– Ies shall be ordered (in an IE container) in the order they appear in object set definitions.

– Object set definitions specify how many times Ies may appear. An IE shall appear exactly once if the presence field in an object has value “mandatory”. An IE may appear at most once if the presence field in an object has value “optional” or “conditional”. If in a tabular format there is multiplicity specified for an IE (i.e. an IE list) then in the corresponding ASN.1 definition the list definition is separated into two parts. The first part defines an IE container list in which the list elements reside. The second part defines list elements. The IE container list appears as an IE of its own. For this version of the standard an IE container list may contain only one kind of list elements.

If an M2AP message that is not constructed as defined above is received, this shall be considered as Abstract Syntax Error, and the message shall be handled as defined for Abstract Syntax Error in clause 10.

9.3.2 Usage of Private Message Mechanism for Non-standard Use

The private message mechanism for non-standard use may be used:

– for special operator (and/or vendor) specific features considered not to be part of the basic functionality, i.e. the functionality required for a complete and high-quality specification in order to guarantee multivendor inter-operability.

– by vendors for research purposes, e.g. to implement and evaluate new algorithms/features before such features are proposed for standardisation.

The private message mechanism shall not be used for basic functionality. Such functionality shall be standardised.
