Question: What happens to a UE's previously stored Multicast Control Channel (MCCH) information when it acquires new multicast MCCH information in RRC_INACTIVE state?
Option 1: The new information is merged with the existing configuration, updating only the changed fields.
Option 2: The UE continues to use the stored information for ongoing sessions and applies the new information only to new multicast services.
Option 3: The newly acquired multicast MCCH information overwrites any stored MCCH information, with the UE discontinuing use of absent fields.
Option 4: The UE ignores the new multicast MCCH information if it was correctly receiving multicast data with the old configuration.
Explanation: Acquiring new multicast MCCH information results in overwriting any previously stored information, replacing the entire configuration. This ensures the UE operates with the most current configuration when receiving multicast services in RRC_INACTIVE state, discontinuing fields no longer present.
