Ubiquitous Home Network
Ubiquitous home network provides any-X(anytime, anywhere, anyservice, anydevice, etc.)
type of services. In other words, home network services are “Bridges to Ubiquitous Service”
• Ubiquitous Home Network Service = Physical Home + Home-like Behavior Outside the Door
• Home Automation is a subset of ubiquitous home network

Network Configuration for Home Network
Home network consists of user access, transport network, home access and In-house network.
 User can access home network services through wired or wireless access network
 Wireless network(eg, Cellular, WMAN) and Broadcasting(eg, satellite DMB) can be a home access network.
 RG(Residential Gateway) has WAN(such as FTTH, HFC, xDSL) and in-house network(Ethernet, PLC, WLAN,
ZigBee, etc.) interface

Features and Scope of the Proposal
It provides interfacing protocols for easy management and control of home
appliances and equipments outside houses.
It provides users with ubiquitous access environment.
It allows service providers to manage overall RG’s and deployed services in an
integrated and convenient way.
It does not specify the connectivity mechanisms or protocols for the home
appliances inside the house, but it recommends to use the concept of brouters
in order for outside users to control home network devices.

Item #I for Standardization : HRIP
Requirements of HRIP
 Integrated management of multi-vendor residential gateways over standardized interface.
 Remote installation and upgrade of RG software and application services in an integrated manner.
 Real-time monitoring of RG’s and their services provisioning status
 Real-time remote control of multi-vendor residential gateways

Conclusions
Home Network Services are expected to be the Killer Applications of many IT
Infrastructures and it will be a bridge to ubiquitous services.
HNW is not active yet, because of Interoperability Issues, Centralized Management
and Control Issues that can support ubiquitous access.
The Standard on centralized management protocol will be serving as the initial
solutions for opening the big market of Home Networking Systems.
The proposed protocols to be standardized include

Interfaces between HOMS and RG(HRIP)

Interfaces between HOMS and ASP Servers(HAIP)

Interfaces between HOMS and USER(HUIP)
Some recommendations on secure communication has been addressed.
We propose HRIP, HAIP and HUIP as three NWIP’s if the proposals fall into
the SC 25/ WG 1
