Mobile Network Improvements for Machine-Type Communications
A 3GPP standards perspective
Toon Norp
Mobile networks need to handle the growth of M2M
M2M is growing fast
22 fold traffic growth from 2011
to 2016, a 86 % yearly growth
5.6 fold growth of number of

5.6 fold growth of number of
M2M subscriptions, from 326
million to 1,906 million
Mobile networks were designed for
voice and mobile data, not M2M
M2M has much lower ARPUs, costs need to come down
Large groups of M2M devices cause a risk of overload
Different characteristics of M2M traffic; little data but lots of signalling
New services and features that appeal to M2M

Network Improvements for Machine Type Communications
Release 10: focus on overload and congestion control
Low priority devices – device
configured to get lower priority

Inbound roaming protection –
barring devices not on their home
or preferred network
APN based congestion control –
signalling requests related to a
particular APN get rejected with a
back off timer

Other Release 11 features:
Triggering – a short message is sent to the device
to wake up the device, e.g. to set up a connection. In
Release 11 implemented with SMSRelease 11 implemented with SMS
PS only devices / without MSISDN – support of SMS
for PS only devices with or without MSISDN
Multiple service enablement frameworks on device –
triggering can address a particular service enablement framework
on the device
Dual priority – dual priority devices can override low priority when
they have something urgent to send
Release 12: Group based features
Group based messaging –
broadcast a single message to a
group of devices in a particular
geographic area
Toon Norp
ETSI M2M Workshop 2012, Mandelieu
geographic area
Group based policing – group of
devices is limited to a maximum
aggregate bit rate
Group based charging – reduce
the amount of CDRs generated for M2M applications
Release 12: small data transfer and frequent small data
Single small data packet: signalling to set up a data connection can
easily take more data than data packet itself
Release 12: send user data on signalling connection
Frequent small data packets create an overload of signalling

events via the Tsp interface

UE power control optimisations
Long paging cycles and DRX
Device triggering enhancements
Triggering via signalling instead of SMS
Overload handling for triggering
Cancelling previously submitted triggers
