MBMS for Internet of Things (IoT)
The present document studies and evaluates the enhancements at the service layer to support massive file delivery for IoT devices. Devices and network entities operating in the typically constrained environment associated with IoT communications (e.g., processing power, storage, battery life, bandwidth) might support the simplified mechanisms and protocols for MBMS and associated unicast procedures as described in the present document, as opposed to the regular MBMS operations as defined in 3GPP TS 26.346. An IoT device described in the present document could be for instance a NB-IoT device or an eMTC device.
The study considers the enhancements/simplifications in the following areas:
- Define the requirements and constraints for different IoT device categories.
- Review the existing multicast/broadcast service architecture in support of MBMS delivery to IoT devices.
