4. Conclusion and outlook

5G mobile networks are now deployed and operational. Their promises of performance, ultra-connectivity and availability are likely to encourage the development of broadcast services of various kinds and with varying requirements, from the retransmission of a live event to the centralized management of hundreds or even thousands of sensors and other connected objects. The nature of such services suggests the use of multicast transmission in the underlying networks.

Having revived and even reinvigorated the concept of the "slice" (network slice), 5G infrastructures claim a natural ability to provide a granularity of quality, security and performance parameters exactly tailored to the nature of the traffic characteristic of each of the services that will be able to benefit from such adaptability.

However, broadcasting services based on group...
