Dr. Jiri Hosek presented on using mobile networks and the IP Multimedia Subsystem (IMS) as a secure and reliable communication platform for smart home devices and Internet of Things (IoT) applications. The presentation discussed using IMS and the Session Initiation Protocol (SIP) as a remote access platform for IoT that provides quality of service, security, and remote device management without new infrastructure. It also described a proof-of-concept smart home gateway that acts as a central connection hub and service enabler to integrate different smart home systems and interface with IMS/SIP for remote access and management.

3. Common Trends in Mobile Networks and IoT Domains
• Most telco markets are challenging and searching
for new business opportunities.
• Massive investments into 4G deployment including
IP Multimedia Subsytem (IMS) as an embedded part.
• Number of connected devices grows exponentially
which is putting unprecedented load on cellular
infrastructure.
• Reliability, Security and Privacy are the key
requirements of any mobile and / or IoT service.
• Customers are constantly asking for device- and
technology- independent ubiquitous connectivity
with high user experience.
Mobile ecosystems are
ready to become the
key communication
platform and service
enabler for IoT / M2M.

4. Telco Networks as Service Enabler for IoT
• Telecommunication networks as base infrastructure providing:
• Quality of Service (QoS)
• Data security and privacy
• Remote device management
• Minimal investment, because no new infrastructure / technology / protocol is needed.
• End-user friendly, because no new end devices are necessary.

5. IMS / SIP-Simple as Remote Access Platform for IoT
• IMS is providing all the required standards, security and
dedicated communication service frameworks for universal
remote access methods.
• IMS is connecting everything and enabling services!
• Session Initiation Protocol (SIP) can be easily utilized as
remote IoT / M2M protocol.
• SIP payload as transportation container for any IoT data.
• JSON-formated user data inside.
• Comparable with other “well-recognized” IoT procotols like
CoAP or MQTT.
• Instant messaging and presence features assure permanent
information sharing.
• IMS/SIP platform can be utilized as a key communication
platform for smart home domain.

6. Smart Home: Platform Provider-centric Approach
• From building
blocks providing to
ecosystem
interworking.
• Smart Home
Gateway as
connection hub &
service enabler.
• Easy remote device
configuration and
management.

7. Smart Home Gateway: Multi-purpose Device
• Smart Home Gateway (SH-GW) provides continuous broadband connectivity, QoS and
software applications to the home.
• Hub of the home network
• It delivers services to, and from, an increasing number of end devices in the customer
environment across different access technologies.
• Managed point of service presence
• SH-GW has to deal with variety of home automation and smart home services:
• Home energy management
• Social media interaction
• Connected storage
• Multi device media streaming
• Key part of the platform provider centric approach!

8. Smart Home Gateway: Main Challenges and Motivation
• Many “solid / closed” smart home and home automation systems running in parallel.
• High need for an integration platform.
• Well defined and universal API between applications, smart home devices and cloud devices is
needed.
• Too many smart home (wireless) interfaces / standards out there.
• SH-GW running as fully modular SW platform is crucial.
• SH-GW to be ready for Network Function Virtualization (NFV/vCPE).
• Do not underestimate the processing power.

9. SyMPHOnY: Smart Multi-Purpose Home Gateway
• Proof-of-concept project jointly realized by Brno University of Technology and Telekom Austria Group.
• SH-GW as a universal integration platform acting as orchestrator for different smart home systems, sensors
and actuators.
• Utilizing (not changing) HW platforms of already deployed IP residential gateways.
• SW as a middleware application
• OSGi-compliant modular design
• Hook on already working standards and recommendations.
• HGI, UPnP, OMS, DLNA, etc.
• IMS / SIP-Simple as primary remote connector.
• Completely open-source solution.
• Providing end users with a possibility for future extension
• Open for any 3rd party application
• All source codes available on GitHub
• Easily portable to other industrial communication platforms.
• Linux-based solution (OpenWRT, Ubuntu Linux)
• Remote configuration via TR-69.
