Study on SEALDD phase 3
The present document is to study on potential enhancements to Service Enabler Architecture Layer (SEAL) data delivery (DD). Specifically, the study is to address data delivery using network multicast/broadcast capability from both 4G and 5G, the SEAL-DD user plane (i.e., SEALDD-UU, SEALDD-S) aspects (e.g., protocol stack(s), user plane functionality description) and the data delivery of new application traffic pattern where the application layer interactions are non-continuous and each of the interactions may be independent with each other.
