Annex C (informative): Mapping the 3GPP and the TM Forum intentExpectation Models

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

The TM forum defines the structure of an intent as a list of expectations with each expectation containing the requirements goals and constraints to be achieved. The expectation is defined to contain 2 attributes – the imm:target and the imm:params. On the hand, the intentExpectation defined in 3GPP (see clause 6.2.1.2.2) contain more attributes some of which (the expectionObject, expectionObjectContexts, expectationTargets and expectationContexts)can be mapped to the TM Forum model.

Following the table to illustrate the attributes mapping between 3GPP Intent Expectation and TM Forum IntentExpectation

3GPP Intent Expectation	TM Forum Intent Expectation
Class Property	Attribute
expectionObject	imm:target
expectionObjectContexts	imm:params
expectationTargets
expectationContexts
