13.1.2.6 P-Abort-Cause
Values of the P-abort-cause parameter are mapped to the values of the provider-reason parameter of the
MAP-P-ABORT indication primitive according to table 13.1/1, except in the dialogue initiated phase for the
"incorrectTransactionPortion" and "noCommonDialoguePortion" values which are mapped to the
"potential incompatibility problem" value of the refuse-reason parameter of the MAP-OPEN cnf primitive.
The source parameter in the MAP-P-ABORT ind takes the value "TC problem".
13.1.2.7 Quality of service
The quality of service of TC request primitives is set by the MAP as shown below.
- Return option: "Return message on error" or "Discard message on error" as required by the network
operator;
- Sequence control: "Sequence guaranteed" or "Sequence result not guaranteed" as required by the
network operator;
"Sequence guaranteed" shall be used when a segmented result is to be transferred (e.g. subscriber
data in response to SendParameters). It may also be appropriate to use Sequence guaranteed
when a series of InsertSubscriberData, ProcessAccessSignalling or ForwardAccessSignalling
operations is used.
TC P-Abort cause MAP provider-reason
unrecognized message type provider malfunction
unrecognized transaction Id supporting dialogue released
badlyFormattedTransactionPortion provider malfunction
incorrectTransactionPortion provider malfunction (note)
resourceLimitation resource limitation
abnormalDialogue provider malfunction
noCommonDialoguePortion version incompatibility
NOTE: Or version incompatibility in the dialogue initiated phase.

MAP-P-ABORT indication
13.2 Service specific procedures
Specific services are mapped to TC component handling services.
13.2.1 Directly mapped parameters
The Invoke Id parameter of the MAP request and indication primitive is directly mapped on to the Invoke Id
parameter of the component handling primitives.
13.2.2 Use of other parameters of component handling primitives
13.2.2.1 Dialogue Id
The value of this parameter is associated with the MAP PM invocation in an implementation dependent
manner.
13.2.2.2 Class
The value of this parameter is set by the MAP PM according to the type of the operation to be invoked.
