NGN-unified platform for creating multi-party profitable Networks

NGN will provide a win-win profit model for multiple parties. Telecom Operators lay broadband networks and provide flexible network architecture and convenient Business Development Interfaces Based on the NGN Softswitch technology for business developers to develop attractive new businesses; business Development/providers will lease the networks of telecom operators to provide customers with personalized and flexible telecommunications services. End users will enjoy the convenience brought by personalized new services, additional fees will be incurred. It can be seen that for carriers, it is vital that NGN can provide a wide range of services and a unified and open business platform. The following describes the NGN solution of Shanghai Bell Alcatel from these two aspects.

The Shanghai Bell Alcatel NGN solution provides diversified businesses and integrates new services of NGN on the basis of ensuring the continuity of traditional businesses. For example, Shanghai Bell Alcatel provides an all-in-one voice, fax, data, and multimedia service for enterprise users by Combining ip vpn, IP Centrex, and video conferencing. The following describes several distinctive NGN services. IP Centrex service not only provides traditional Centrex services, but also integrates multiple services, such as conferences, unified messaging, and voice mail. You can not only use WEB portals for self-service, but also use integrated office software to manage personal communication information while working. This service is flexible, scalable, and operable.

Video Multimedia conference service

You can use virtual conference rooms to provide multi-party video conferencing services for users in different regions, using different terminals, and using different access methods. This Service supports various types of terminals, including PC + camera, Business Channel PDA, video phones, IP phones, and mobile phones. This application can easily create a conference call for audio or video through the web portal or using a personal/enterprise directory. First, the participants will receive a message notification, and they will receive an application invitation during the meeting time. In addition to voice and video communication, the Conference can also transmit text information and provide functions such as electronic whiteboards, shared documents, and tables. Conference managers can monitor meetings through web interfaces, such as deleting participants, isolating participants, and managing video quadrant (Merging video images. Compared with traditional video conferencing services, the network and terminal costs of video conferencing systems are greatly reduced.

Wireless voice　

By deploying WLAN in hotspot areas or office areas, you can use wireless access to connect users to the NGN network to provide users with wireless voice services.

Unified message

The unified messaging service can integrate various types of messages, such as voice messages, faxes, e-mails, short messages, multimedia messages, and instant messages, into a single messaging system, you can flexibly configure business attributes based on your individual needs (settings, status, terminal capabilities, and message content) and select the most appropriate method to send messages to your destination.

No. 1 pass　

The No. 1 Communication Service uses a unique No. 1 communication number as an external communication number. The user's mobile phone number, PHS number, and fixed phone number can all be associated with this one. No matter how the actual phone number changes, others can contact the user as long as they know the phone number. When applying for the No. 1 service, you can set the phone numbers used for actual transfer according to your habits. These numbers can be NGN, mobile phone, PHS, or fixed phone numbers.

In the next generation network, a unified and open business platform is crucial. The Shanghai Bell Alcatel NGN solution provides a unified and open business platform. Uniform means to provide a rich set of NGN services to users through a set of business platforms. Openness means that the underlying network capabilities can be opened to service developers and authorized, business developers can easily control networks to develop new NGN business applications.

Shanghai Bell Alcatel has built an open business platform (OSP) to provide NGN services through a unified architecture. It provides complete NGN business solutions from the following four aspects: first, softswitch provides 4/5 categories of voice and fax services and basic video and multimedia calls. Second, Softswitch communicates with SCP to control services and provides the same intelligent network services as PSTN; third, multimedia services are provided through the Multimedia Application Server (MMAS), which can be connected to a third-party SIP application server through the SIP interface. The SIP Application Server is an integration platform based on the SIP application, supports all types of applications and enables a large number of third-party application providers to continuously develop new businesses. The SIP Application Server provides programmable features and can be easily expanded to support new businesses and their features, provide parlay gw on the multimedia application server, allowing third parties to use network resources to develop business logic through open interfaces to form new businesses. Parlay gateway is the core component that provides Parlay API functions, supports all Parlay API services (mobility, user interaction, messaging, call control, and connection management) And core architecture interfaces.

To sum up, Shanghai Bell Alcatel's unified NGN business platform not only supports traditional communication services, but also provides standard SIP protocol and Parlay API interfaces. This open architecture will break the "vertical" model of business development in the past, and lead to loose coupling between business and lower-layer networks, so as to introduce the Internet business development model in the telecom field, shorten the business development cycle and improve the service delivery capability of operators.
