Question: In an IMS environment, when utilizing the Nmf_MRM_Update service operation to update media resources, what happens to the Termination ID when adding a new termination to a media context resource?
Option 1: A new unique Termination ID is automatically allocated by the Media Function (MF).
Option 2: The Termination ID must be set to 'null' by the consumer Network Function (NF) to indicate addition.
Option 3: The Termination ID remains unchanged from its previous value, if any.
Option 4: An error is generated if no Termination ID is provided for the new termination.
Explanation: When adding a new termination to a media context resource using the Nmf_MRM_Update service operation in an IMS environment, the consumer Network Function (NF) must indicate this addition by setting the Termination ID to 'null'. This signals the Media Function (MF) to allocate a unique identity, ensuring seamless management of media resources within the specified context.
