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

and interoperability with high user experience.

Mobile ecosystems are

ready to become the

key communication

platform and service

enabler for IoT / M2M.

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.

SyMPHOnY: Implemented Use Cases

• Alarm Systems

• Receive and process alarm events via FXS interface and forward them as SIP messages.

• Smart Metering (Wireless M-Bus / ZigBee)

• Electricity

• Water

• Solar energy

• Environment (temperature, humidity)

• Home / Entertainment Lighting System

• Philips Hue Bulbs system

• Home multimedia framework

• UPnP / DLNA Push stream of actual information from SH-GW to SmartTV

• Home automation

• KNX building control system

11


SyMPHOnY: Communication Model

• Main goal: secure, reliable and ubiquitous access to any required information

• Local vs. remote

• Smart home gateway as SIP client processing data via variable HAN connections and forwarding to remote SIP clients (3rd party services)

• IMS / SIP as trusted communication channel

• SIP as comparable IoT protocol

• Pros:

• Already available technology

• Transport protocol independent

• Data transfer via trusted network

• SIP Presence utilized to notify device’s status

• Instant messaging approach

• SIP client as standard SW tool on most UEs

• Cons:

• Limited implementation on “dummy” sensors

12


SyMPHOnY: Data Model

• Sensor data stored inside the SIP message payload

• Each individual device/sensor is represented by unique feed ID • E.g. serial number

• One feed may include more data streams • E.g. values for hot and cold water consumption

• Data structured by unified JSON format

• Similar approach like CoAP or other IoT services

• SIP client parses SIP message and extract JSON formatted data

13


{

"feed":"475706330",

{"version":"1.0.0",

"datastreams":[

{"id":"temperature",

"current_value":"27.1"} ]

}

}

SyMPHOnY: Data Processing and User Interfaces

• All data received, processed and stored in local DBrunning on SH-GW

• Data stored in JSON format.

• Definition of several archives used to for storing data with various periods and resolutions.

• Data aggregation function implemented to minimize thedatabase size.

• Energy Dashboard web interface

• All actual information about smart home including figures, reference rankings and configuration interface.

• Mobile end-user interface

• Native application for smartphones (Android, iOS)

• Web-based visualization platform

• DLNA stream on SmartTV

• UPnP Discovery + DLNA Push features• Smart home overview

• Critical events

SyMPHOnY: 4G Testing Infrastructure

• Unique full-scale LTE-A (4G) deployment at BUT

• LTE-EPC-IMS, Rel. 10

• Complex mobile heterogeneous system:

• LTE + WiFi

• 5 LTE cells, 2 eNBs, 2 WiFi APs,

• 2x 700 MHz (Band 17 – AT&T) – indoor, 5 MHz FDD, 2x2 MIMO

• 1800 MHz – outdoor coverage

• 2600 MHz – indoor unit, 2x2 MIMO

• WiFi bands: 2.4 and 5 GHz

• Are you missing infrastructure for your IMS-based services?

• Let‘s cooperate!
