Operators through the home gateway to open the "last 10 meters"

The development of family business is in the embryonic stage, has not yet formed the unified norm and the business model, the operator should seize the opportunity, from simply provides the Internet access to the broadband-based integrated service provider transformation, by the home gateway, the IPTV set-top box, the integrated Broadband Intelligent terminal, the WiFi handset, Video telephony and other broadband network terminal equipment to form a home network, to provide users with appropriate, easy-to-use, convenient, fast integrated business, which is the key home gateway.

"Home gateways are important, and only home gateways can combine disparate, complementary technologies and control them on one device, making it easier for operators to provide some new converged services." "In the recent World Communications Conference Broadband Development Forum, China Telecom Chief Engineer Wei on how broadband business landed, feeling the role of the home gateway is huge.

Experts at the Shanghai Institute of China Telecom said that the home gateways used to integrate multiple digital application devices in the home were attracting much attention. The driving force is from the customer's business needs, on the other hand, is favored by operators.

For operators, the home gateway is the best weapon to enhance the penetration of its business to individual users, and it is the extension and extension of its access network. With a home gateway, operators can shorten their distance from users and facilitate the expansion of new business and value-added services. The home gateway allows operators to move from "last kilometer" to "last 10 meters".

the inevitable choice of the whole business

At present, fixed network operators are actively implementing FMC because of the substitution of mobile network to fixed network service. FMC has become one of its preferred tools for getting out of the woods. FMC system needs a large number of home gateway terminal Equipment, which further promote the introduction of family gateway standards and technology maturity. The FMC business, launched by BT and France Telecom, is a typical case of successful commercial home gateways. Therefore, the home network can be considered a converged network, that is, the integration of fixed and mobile networks.

The former Ministry of Information Industry, Telecommunications Economic Expert committee Secretary-General, telecommunications experts Yang Peifang said that in the pattern of full-service competition, broadband network will play an important role. He believes that broadband multimedia network has more potential advantages, is the core of future communications development, under certain conditions, the mobile network will be only one of the broadband Network access network, and will not produce the current "substitution" effect. The realization of this prediction requires a strong support of this link in the home gateway.

Home Gateway, as the core of family informatization, bears an important role. Wei that the so-called home network is to achieve the interconnection of multiple devices to form a network to achieve interoperability and resource sharing, is the public network functions of the business to the home extension, the main goal is to make all kinds of unrelated networks, such as fixed network, Internet, mobile network, cable TV network to achieve business integration, and even unified management. Home gateway is the interface between home network and external public network, which provides access and control functions for various home network services. To realize the whole business operation, the construction of the home gateway is the key of the operators.

Open with 0 configuration is the focus

Wei said that China Telecom attaches great importance to the customization and deployment of home gateways, in the deployment, summed up the most important experience is the open middleware architecture, China Telecom has developed a middleware core module, is conducive to the development of new functions and new business, enhance the operator's ability to control the business.

In addition, network deployment home gateway and terminal Integrated Management system is ITMS, China Telecom has achieved five kinds of ITMS and more than 10 kinds of home Gateway TR-069 interoperability. Wei specifically mentions that the 0 configuration of a manageable controllable level user of a home gateway is important because most users are not experts, so be sure to implement zero configuration. This means that operators need to have more control management ability, stronger business support ability.

At present, China Telecom "My E Home" business overall structure to provide three aspects of communication capabilities, the first is E home communications, multi-account Internet access, e home phone, WLAN roaming, FMC, the second is E home information, custom and push, number Blackstone, home monitoring, family payments, and the third is E home entertainment, including IPTV, Connected to the sky dedicated channel, film and television, music games and so on.

To promote my e home, China Telecom from January 2008 onwards to the network to implement a comprehensive transformation of high-end users to deploy home gateway E8-b and Support system boss, CRM, service opening system, billing system transformation, but also to complete the support of SIP SMS and other business functions of the transformation, building BAC business Platform, VoIP with the same number, the same vibration, ring tone, click Dial platform and VoIP roaming platform.

Solve operational issues

A family gateway-based business must be operationally manageable, so there is a need for a multifaceted ability to operate a manageable home gateway and home network to support a variety of carrier-grade businesses and extend the application to the home. The most prominent issues today are QoS management and scalability issues.

Home Gateway is an advanced integrated gateway, and to realize the integration and collaboration of home Network, a unified QoS policy must be required. From the horizontal level, in order to work together inside and outside the network, we need to provide qoswan/lan mapping, and from the vertical level, the access network and upper layer protocol also need QoS interface and collaboration. At the same time, because different business needs to go through the home gateway, how to distinguish different business flows in the complex network mode, and make the appropriate scheduling for different priority traffic, the QoS puts forward high requirements.

Industry experts believe that the home gateway as part of the carrier network, must have remote control, remote detection, remote settings and other capabilities. The management of the home network also includes the management of the gateway itself, the management of gateway-connected devices and the Plug and Play under 0-touch service.

On the other hand, as the home network is the center of the integration of various industries, its standardization is also different, has become the IEC, ISO/IEC/JTC1, ITU and other international Organization for Standardization of the focus of the controversy. There are areas where standard overlap or duplication exists between these organizations. For operators, home gateways should integrate different types of applications, based on the different external access networks and different business models of different service providers, the home gateway must be focused on extensibility. Telecom operators are faced with the problem of how to integrate modules to meet the needs of different users.
