Introduction
Joined research project between
Sietse from Windesheim University of Applied Sciences as a part of his PhD project and
Robert and Erik from the Dutch Research institute TNO
Within this conference the results of the first phase within this project are presented.
Any suggestions and feedback is welcome

More extramural care to reduce costs
Volunteers and health professions are nomadic
(Available) any- where and anytime
How to inform a network of nomadic health professional and volunteers in a telemonitoring environment
In 2020 approximately one fifth of the population is elder the 65
So we see an increase in the demand for specialized healthcare services.
To deal with this situation within the Netherlands, we see a policy for this group to live longer within their
own permises

10. Wide Area Network Next generation network infrastructures
Trend
All-IP network
Fixed as well as mobile based on the Internet protocol
IP will be used for data as well as voice communication
IP Multimedia Subsystem and SIP
Reason for all-IP
Cost reduction and flexible
IP multimedia subsystem based on SIP is considered as a key element in realizing the All-IP network.
It makes it possible to realise IP-based communication services in a standardized manner
IMS is based on the Internet Standard SIP
05/12/2018

11. Internet standard for signaling and session control
Next generation network infrastructures Session Initiation Protocol (SIP)
Internet standard for signaling and session control
e.g. VoiP session, conference call session,
but also streaming multimedia content
Main purpose of SIP
User location
(SIP address:
Negotiation
Call management
Changing features during session
User location translation of SIP to network address. Unique identifieer
Negotiation e.g. which codex do we use during video conference
Call management (add, drop, transferring participants)

12. Next generation network infrastructures IP Multimedia Subsystem (IMS)
Goal: provide service enablers within the network which can be used for network applications like telemonitoring.
Control services en charge for it and QoS, Roaming for operators
Based on IP protocols. This way it integrates the mobile and cellular world

14. Next generation network infrastructures Content Repurposing Platform
CRP allows multimedia content to be used for different purposes then the one it was originally meant for.
Solves the mismatch between content origin and content destination
E.g. : Screen size, color depth, audio/video codec, file size, protocol etc…
Protocol – HTTP – SIP
A CRP allowes mm content to be used for different purposes then the one it was originally mend for.
Give content a new purpose then where it was originally

21. Conclusions and Recommendations
Wireless Sensor Networks can be used within the home of the elderly for fall detection
SIP and IMS offer service enablers that help realize a telemonitoring solution.
There is a need for content repurposing in order to be able to distribute the correct format content to each specific device.
IMS is not completely implemented yet.
