Question: When a MnS (Management and Network Services) consumer wants to cancel subscriptions, what is the recommended approach if they want to cancel all subscriptions associated with their consumerReference?
Option 1: Provide the corresponding subscriptionId for each subscription in the cancellation request.
Option 2: Leave the subscriptionId parameter absent in the cancellation request to imply all subscriptions.
Option 3: Use a separate, dedicated 'Cancel All' operation specifically designed for this purpose.
Option 4: Utilize IOC NtfSubscriptionControl as specified in an alternative TS document for comprehensive control.
Explanation: According to telecom management best practices, when cancelling all subscriptions at once without specifying each one individually, the recommended method is to leave the subscriptionId blank. This signals the system to apply the action across all entities linked to the consumerReference. Note that while IOC NtfSubscriptionControl offers a more integrated solution for future-proof management, Option 2 directly answers the question as posed.
