TR 23.720 (SA2)

Cellular Internet of Things

V13.0.0 (Wzip)  2016/03  94 p.

Rapporteur:  Mr. Jain, Puneet
See also:  CIoT-related TS/TR

The present document studies and evaluates the architecture enhancement to support ultra-low complexity, power constrained, and low data-rate 'Internet of Things' devices.

The study will consider architecture enhancements/simplifications in the following areas:
  • Support of highly efficient handling of frequent and infrequent small data transmissions (e.g. based on the traffic model in TR 45.820) with minimised overhead for system signalling without compromising e.g. security.
  • Support of power consumption optimisations and/or using existing ones that have been developed for EPS or GPRS.
  • Assessing simplification of Mobility Management and Session Management procedures.
  • Support of paging optimisations for UEs requiring coverage enhancements.
The present document will also consider system architecture alternatives to address the points above.
