Home Services Areas (P1401)
User needs in these areas– Mass market relevance
“It shall make money”– Help customer up to the very end ‘it
will work’
How support is provided?– Telecom: “Works first time and forever”– Connectivity support– Service support

Infrastructure for home servicesThin gateway with split functionality
– Cheap gateway: target < 100 €– Public: access the Internet– Secure: authentication, QoS, remote
maintenance
Easy to use, (plug &) play– Applications maintained in Telecom

Service Identification inEntertainmentService Scenarios:Video on Demand (VoD), music/games on demand
– “Killer application on TV is TV” Ensure that video can be enjoyed on the TV
– A) Set-top box to stream VoD to TV– B) PC and mediacenter for streaming from PC to TV
Access to home content– “My pictures/music/video stays at home”– “I want to access my content wherever I am”– Need to have one storage place from all home devices– Network storage unit attached to gateway/home network
E
Josef Noll, 23.6.2005 IST, OBAN workshop
Infrastructure “Video on Demand”secure mode supports QoS control
– User may have limited (e.g. 512 kbit/s) bandwidth on public channel
– secure channel can provide 2-3 Mbit/s
Optional: Providing authentication & payment
– Through Telecom infrastructure

Postulate 7: Services set-up have to include infrastructure
Supports access from outside– Access from outside into the home:
email, web, iTunes, pictures– Dedicated users
External storage for all my PCs– Link in as network disks– Dedicated disk space for each user
Small (size of smartphone) Linux PC2 W standby powerConnections to USB disksReasonable price (100 €)(Remote maintenance)

Service Identification inSocial Inclusion/eCareService Scenarios:
Sending pictures/video from mobile to home TV– Grandchildren includes grandparents in their life by sending mobile phone
messages to dedicated channel “on home TV”– Video streaming from events (soccer, church) to home
Support at home after hospital visit– Patient comes home after hospital visit– Wireless surveillance equipment collects data and sends to parents & hospital
Elderly e-Care– Old people stays home with remote professional assistance, instead going to a Day
Centre.– Video-telephony service to the Service Centre or to other client, associated to diary
routine medical measurements, remembers to take the medical drugs, an wireless emergency alarm (optional).

Service Identification inPersonal EnrichmentService Scenarios:Dancing lessons at home
– Most people want to learn something new– Prefer first steps in an anonymous environment (don’t want to get
blamed)– Searching for friends with similar interest
Hardware store, enhancing the business– Selling “do it yourself” articles is one thing, providing support more
complicate– Example: Hardware store to supply goods and online support

Service Identification inHome Automation/SecurityService Scenarios:Security surveillance of the home
– Closed systems existing already today. Function with little customer interaction.
– Customer wants to see “what is going on”. First interaction to mobile phone
– Includes “baby watch” functionality
Home automation– might become interesting in the social context: “What is my mother doing”
and energy saving. Currently market for early adapters.
Remote Access to home content– “My pictures at home” – already handled in (E) scenario

Authentication/Security infrastructureSecurity depends on application
– Nice to know: WLAN network access– Need to know: email, Intranett– Have to know: VPN, (eCommerce)
Higher level require more than just username & passwordhttp://www.openauthentication.org/ suggests 3 methods
– SIM authentication (GSM, EAP-SIM,…)– Public Key Infrastructure (PKI)– One-Time-Password (OTP)
The Mobile phone has all three: SIM, PKI, and OTP– Near-field, area and Far-field communication (NFC, WLAN, GSM/SMS)
Challenge: Usability and exchange of credentials to “my working devices”

Conclusions / PostulatesUsers services with highest potential
– Sending picture & support at home– VoD & remote access to “my content”– Personal enrichment, examples: DIY shop with support, dancing– Safety & Security
Seamless service access is the key to successful services Focus on home services for the broadband wireless accessThe SIM/mobile phone provides communication to items and groups.Home infrastructure: Split Gateway functionality for Service Provisioning "You can't sell a residential gateway": Services set-up have to include infrastructureAuthentication and Security: SIM card & Mobile Phone (with NFC and PKI) is security infrastructureHome network and Mobile networks provide advanced (B3G) communicationsWhat’s next: Seamless access of all terminals; Personalisation; Adaptation of services and content.
