© Fraunhofer AICOS Outline Context & Motivation eCAALYX architecture Home Gateway overview CWMP extensions

© Fraunhofer AICOS The demographic change Inversion of the demographic pyramid (particularly in EU) Healthcare costs Estimated annual growth of 4.6%with age Reform pensions Aged dependency ratio increases Religion,...

© Fraunhofer AICOS Focusing on Healthcare Objectives [More than ever, we need to] Increase the healthcare system efficiency More efficient patient monitoring More frequent and better informed Increase prevention and awareness Detect conditions earlier Educate people Reduce the number and average period of hospitalisations One approach: home healthcare systems

© Fraunhofer AICOS Home healthcare systems Components Sensors (Vital signs, others...) Communication 'box' User interface Web-on-PC TV 'channel'... eCAALYX Enhanced Complete AAL eXperience EU-funded project under the AAL JP (call 1 – chronic patients) Telcos, Sensor manufacturers, Hospitals, IT

© Fraunhofer AICOS System Management Relevance It is a challenging deployment scenario Technology in a non-expert environment Seniors private homes Long-term deployment Chronic patients System management is crucial for the solution viability Both for commercial viability and user-acceptance Telcos already have to deal with a similar problem (to a smaller extent)... and the infrastructure is there... it makes sense to reuse it

© Fraunhofer AICOS Telco Remote Management Manage Home Gateways, STBs, VoIP phones Based on the CWMP (CPE WAN Mngmt Protocol) Defined in the Broadband Forum's TR-069 Open standard Components CWMP-enabled CPE (Home gateway, STB, etc) Auto-Configuration Server (ACS) in the back-end Operational center Feeds/uses information to/from the ACS

© Fraunhofer AICOS CWMP Protocol Layer Summary LayerDescription CPE/ACS ApplicationThis application is locally defined as it is not specified as part of the protocol. RPC MethodsSpecific CPE WAN Management Protocol methods. SOAPStandard XML-based syntax. CPE and ACS exchange SOAP messages. HTTPStandard HTTP 1.1 (CPE acts as the HTTP client and the ACS as the HTTP server). SSL/TLSStandard Internet transport layer security protocols. TCP/IPStandard TCP/IP.

© Fraunhofer AICOS Can we reuse it to manage home healthcare systems?

© Fraunhofer AICOS Extensions Required 2 new entities (for the home gateway) Sensors Communication technology details, PIN, driver,... Caretakers Message exchange protocol library, communication details, patient ID... 2 extension possibilities Creating new or extending existing data models: able to reutilize CWMP existing methods New CWMP RPC methods: requires deeper changes to the ACS logic
