Question: In the URCMP Event Notification Procedure, what triggers the UCMF to initiate an Event Notification Request towards the MME with an Event Type IE set to 'Creation of Dictionary Entry'?
Option 1: Deletion of a PLMN-assigned UE Radio Capability ID
Option 2: Creation of one or more new dictionary entries in the UCMF since the subscription creation time
Option 3: Switching to operate based on IMSI (International Mobile Subscriber Identity) for a particular type of UE
Option 4: Update of an existing PLMN-assigned UE Radio Capability ID
Explanation: According to the URCMP Event Notification Procedure, when one or more new dictionary entries are created in the UCMF since the time of subscription creation, the UCMF initiates the Event Notification Procedure. This is specifically relevant for notifying the MME about new dictionary entries, ensuring both entities remain synchronized regarding UE radio capabilities.
