The present document studies and evaluates architectural enhancements for Machine-Type and other mobile data applications Communications.

Specifically, the following system improvements are considered:
  • Triggering enhancements which includes the following aspects:
    • Device triggering enhancements including T5 based device trigger and other triggering efficiency optimizations.
  • UE Power optimizations which includes the following aspects:
    • Optimizations to prevent battery drain (that may come from e.g. frequent changes between idle and connected mode or too long periods in connected mode); and
    • Lower UE power consumption as per the service requirements (TS 22.368, clause 7.1.1).
  • Monitoring enhancements which includes the following aspect:
    • Monitoring as per the service requirements (TS 22.368, clause 7.2.8).
  • Group based features which include the following aspects:
    • Fulfil the group based policing requirements (TS 22.368 clause;
    • Fulfil the group based addressing requirements (TS 22.368 clause; and
    • Fulfil the group based charging requirements (TS 22.368 clause 7.1.5).
The end-to-end application layer aspects between UEs and Application servers including SCS (which can be located outside or inside the network operator's domain) are out of the scope of this study. However, the transport services as provided by the 3GPP system and the related optimizations are considered in this study.

The present document analyzes architectural aspects to achieve these objectives and to gather technical content until it can be included in the relevant technical specifications.
