OSGi Community Event 2010 - Case Study Report on i-House experiments using intermediate service platform based on OSGi technology (Takefumi Yamazaki - NTT)

1. Takefumi Yamazaki | NTT
Case study report on i-House
experiments using intermediate service
platform based on OSGi technology
This work was done as part of the R&D project “Development of energy saving
home networking technologies “ organized by ‘Ministry of Internal Affairs and
Communications, Japan’.

2. Aim of this project
• Develop a platform that can produce various kinds of
home network services easily at lower cost.
• And promote standardization to realize such platform
Key concept: “Intermediate service platform”
• Bridge between service providers and home networks

• Provide both service providers and users with functions needed
to produce home network services.
(i.e. “Cloud service” for building home network services.)
• Two Layer structure:
• Service depend/related: Service Management platform
• Service-independent: Home network management platform

4. Core technology on this PF: OSGi
• OSGi-PF is adopted as core function of home network
management PF
• Many services in this project were realized by
installing new modules (bundles) to one HGW.
 Services & bundles used in the project (next slide)
• New services are flexibly and easily added or deleted
on demand by OSGi PF working together with other
functions in the “intermediate PF”. (service portal
function and service contract management function)
 Experimental study (explained later)

◇ Procedure of service subscription with Intermediate PF
1. End-user can select a service from a list of available services by
service portal function. (① 、 ② )
2. The service management function decides if the selected
service is available by checking the state of resources on HGW.
（ ③）
3. When the subscription is accepted, the OSGi PF is activated to
install the corresponding bundles to HGW. （ ④、 ⑤）

◇ Execution of sample AP : “Home control service based on emergency
earthquake reporting”
4. An emergency earthquake reporting alert is triggered at the
server manually. (⑥)
5. After HGW receives the signal from the server, it sends the
control commands to the devices based on AP bundles.(⑦)
6. The devices work by following the commands.

13. Emergency earthquake reporting
• Provide information about seismic center, scale, and the time:
immediate estimation after the earthquake occurs.
• The information is presumed to come from P-waves captured at
an observation point near the seismic center.
• This service has been available for the public since 2007 in Japan.

15. Summary
• Case study report at i-House based on nation R&D project
• Successfully visualized the mechanism of “intermediate
service PF” to produce various kinds of home network
services flexibly.
