Abstract: A system and method for call selection and migration in a NG-CU over NGRAN is disclosed. The system and method comprises a CP VNFC assigning a call initiated by a user to a source user plane VNFC. A management VNFC detects an overload traffic condition upon receiving the assigned call by the source user plane VNFC from the CP VNFC. The source user plane VNFC selects the call to be migrated with a higher migration preference value to another VNFC and signals CP VNFC to initiate call migration. The CP VNFC then migrates the selected call through at least one GTP tunnel to a target user plane VNFC. The source user plane VNFC then forwards the target user plane VNFC a request to handle complete trafficking of the migrated call.

Abstract: Techniques of finding a meeting time involve recommending a meeting time based on attendee meeting history. Along these lines, a meeting scheduler accesses meeting logs that contain trends involving previous meetings to which attendees were invited. For example, such meeting logs may indicate whether an attendee accepted meeting invitations to meetings occurring at particular times during a workweek. Based on the accessed meeting logs, the meeting scheduler recommends a time at which to hold the meeting. For example, the meeting logs may indicate that an attendee declines invitations at certain times of the day, or that another attendee has flexibility during a time labeled as unavailable in the calendar. The meeting schedule then sends a message to the meeting organizer that contains the recommended time.
