Study on 5G message service for MIoT
The present document develops use cases of message communication for MIoT, identifies 5G Message (5GMSG) service potential requirements, and identifies potential requirements on 5G system. The use cases include the following scenarios:
- Efficient message communication
- Low delay message communication
- Group message communication
- Multicast and broadcast message communication
- High density of UEs message communication
It also provides a gap analysis between the new requirements of message communication for MIoT and the existing operator’s message services/3GPP network capabilities, and recommends the future work for the standardization of 5GMSG service for MIoT.
