Question: In RANAP signalling, how should Information Elements (IEs) be ordered within an IE container in a RANAP message?
Option 1: IEs can appear in any order, with no restrictions on their occurrence.
Option 2: IEs shall be ordered in the sequence they appear in the object set definitions.
Option 3: The ordering of IEs is determined by the receiving entity's preferences.
Option 4: IEs are not required to follow a specific order, but their presence is mandatory.
Explanation: According to RANAP definitions, for constructing RANAP messages, Information Elements (IEs) within an IE container must be ordered exactly as they appear in the object set definitions. This ensures consistency and predictability in message structure, facilitating efficient parsing and processing of RANAP messages.
