Priority-based CBS Transmission for Multiple CBEs in 5G Networks

This paper relates to the requirements of interworking for transmitting CBS (Cell Broadcast Service) message according to the priority in 5G mobile communication network in Korea. We propose a structure and function design plan, and pre-conditions for the priority-based CBS transmission service. This paper also contains some requirements of additional functions. When a CBS with a higher priority comes in while broadcasting the previous CBS, regardless of the 30 second rule, the CBS message in-broadcasted is stopped and a later CBS with a higher priority is transmitted instead.
