Why LTE for IoT
By using LTE as the connection: CPE can be installed virtually
anywhere As long as have coverage and power*
Other benefits : IP addressing can be IPv6 so as to
scale to the IoT. Power to the CPE can be confirmed
simply through radio signaling Security of the radio link is inherent LTE is IP based and can scale to
billions of devices Last mile connection loss is not a
concern
LTE removes major network challenges: No need to punch holes through
firewalls for the protocols that could change on a regular basis
No need to have a NAT keep alive No need for IPSec or SSL for security No need for Ethernet to be wired to the
CPE No need to configure the WiFi
credentials of the backhaul router for WiFi 802.11u may help in the future thoughFrom this:
To this:

Network Awareness
* Power from battery may be sufficient with UEPCOP

Why not LTE
Challenge Solution
Cost of a connection is significant Reduce the session footprint, increase the value the connection offers
LTE is not pervasive Operators may have national coverage but what about international
Chip sets are expensive True but coming down and LTE is the future, 2/3G spectrum will be re-farmed
SMS based application so 2G is sufficient
LTE is all IP and IPv6 capable
Wi-Fi is cheaper but is susceptible to interference
LTE is licensed and spectrum is dedicated
Battery Concern Devices can sleep

Provide APIs for the M2M applications to query session / device data Identity mapping session info (APN, QoS, IMSI, PLMN), Session status (active/offline) Roaming status Location SLA Network congestion status
Network State Examples
Provide ability for the application to subscribe to notifications Mobility events Location changes Roaming status changes Congestion status change KPI threshold exceeds

GSMA oneAPI
The GSMA oneAPI is the 3GPP method to expose network function to 3rd parties. The following capabilities are supported in version 3 of the oneAPI specifications:
Location
SMS
MMS
Payment
Device Capability
Data Connection Profile
Third Party Call
Anonymous Customer Reference
REST based with the option to subscribe to notifications Some operators advertised as using the framework Use cases may not be appropriate for bulk M2M applications 3GPP R13 SEES/AESE work looking at OMA and GSMA platforms

MONTE Framework• SCS/AS (M2M
Application) subscribes to service provider for device events
• API GW decides which network element to install triggers to report the event

Architecture Enhancements for Service Exposure Change “exposure layer”
to SCEF
Adds description of “Abstraction” along w/ other minor changes
Adds an example by way of SMS to show how SCEF can be employed

Why Ping when a TAU is nearly the same
M2M server makes simple request to report when devices do not report in
API GW installs the subscription for TAU reports for this M2M customer
MME reports successful TAUs
API GW determines that after the TAU timer, one is missing and reports to M2M server

MTC Application Delays Sending DataMTC application delays sending data until device becomes active
Details: MTC application registers to be notified when device activates. Once device active sends data.

3GPP, OMA, GSMA, Services Providers and vendors are designing solutions to expose network state to 3rd parties
Exposure layer simplifies the implementation to 3rd parties
However adds complexity (cost) to SP’s
Is the cost/benefit there?
Network SLA and protection sufficient?
Are there sufficient use cases that need awareness?
What will M2M applications need from their connection to the Internet?
Network Connection Status Value
Thank you.
