M2M applications and 3GPP cellular networks

Genadi VelevNEC Laboratories Europe

A cellular operator:Can any of the 3GPP technologies (GSM, UMTS, LTE) be used to meet the M2M requirements?

Low device price Long battery life

NOTE: 3GPP uses Machine Type Communication (MTC) term beside M2M


▌ Traditional applications Voice, multimedia, large data Highly mobile devices No strict requirements for chipset

price and battery life

Challenges for 3GPP cellular networks

▌ M2M application chatacteristics Business: low ARPU Device requirements: low price, long

battery life Data chatacteristics: small data,

periodic, (in)frequent


▌ Why 3GPP cellular network as transport for M2M applications?

3GPP System Architecture evolution (1/3)

▌ Release 10 (NIMTC) Started with a dozen of features.... Congestion/overload control in the network

• low access priority devices• ... later dual priority devices• Extended Access Class Barring (EAB)

▌ Release 11 (SIMTC) Device Triggering TS23.682 (reachability from the M2M App server)

• New network function MTC-IWF (Tsp interface to 3rd party) SMS in MME (LTE only deployment) MSISDN-less support

▌ Release 12 UE Power Consumption Optimizations (UEPCOP)

• Power saving mode (PSM): UE not reachable during PSM state. Small Data and Device Triggering (SDDTE)

• Core Network assisted eNB parameters for small data transfer

=> Release 13 ongoing (following slides)

3GPP System Architecture: Release 13

▌ Architecture Enhancements for Service Capability Exposure (AESE) Architecture agreed Exposing network services to 3rd party

▌ Monitoring Enhancements (MONTE) Configuring monitoring events in the network Exposing network information to 3rd party for troubleshooting

▌ Group based Enhancements (GROUPE) Group based messaging

• Broadcast/multicast to a group (opt. in a geo area)• Group addressing and identifiers

Group based policing: QoS policies, congestion control

=> More M2M-related features are studied (HLCom, DECOR, eDRX)

3GPP Radio Access (RAN/GERAN)

▌ RAN1/2 (UTRAN, LTE) Release 11

• Implementing SA specs on congestion/overload control• Study on Low Cost UE

(low data rate, 1 RX antenna, in-building coverage, half-duplex)

Release 12• Specified a new Cat0 UE (result from Rel-11 “Low Cost UE”)

Release 13• RAN enhancements for small data transmission in LTE

▌ GERAN (GPRS) Rel-12: Study of Power Saving for MTC Devices (uPoD) Rel-13: Support for Ultra Low Complexity

and Low Throughput IoT (Cellular IoT)• Data rate >= 160 bps• Battery lifetime > 10 years• Massive number of devices (40 per household)• Optionally non backward compatibility

▌ In the past (2G, 3G, 4G)The service requirements (SA1) did not consider M2M use cases=> hence, later enhancements were needed

▌ In the future (5G, 2018~2020)SA1 to specify use cases based on M2M applications (e.g. ultra-fast network access, e.g. ~1ms latency for automated driving, industrial sensors, robots. Described in docs S1-144361, S1-144384).

Towards 5G


▌ 3GPP standardizes M2M-specific features (since ~2010) Network internal optimizations for M2M characteristics Cheep and power efficient M2M devices (by RAN/GERAN WGs) Unified access to/from M2M service providers (by SA WGs)
