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

Home network consists of user access, transport network, home access and In-house network.


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

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

Specifically, HRIP must be independent of various physical interface and control protocol

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
