NGN (Next Generation Network) is a converged network including voice, video and data on a single infrastructure based on IP.

NGN is an integrated structure with the existing network structure of multi-service network based on available infrastructure.

Characteristics of NGN:

+ Use soft switching technology.   
+ Network converged voice and data, fixed and mobile o broadband network to provide multiple services.

Soft Switching (Softswitch): this is the switching device replaces the PBX switching equipment bulky hardware. The network of different services are connected to each other through the control of a single PBX, PBX switching software based on Softswitch. Switching software is considered the heart of NGN.

Soft Switch System allows networking between enterprises and suppliers or between the enterprise network with each other. It has mechanisms for protection, handling both signaling and media stream.

Model

NGN construction system includes the following elements:

+ To build an IP backbone for the system
+ Building connections with broadband Internet access and PSTN connectivity to IP backbone
+ Building Softswitch signal processing, control, and set call routing or multimedia connection
+ Building applications on the platform had

 

Here are the steps required to build the NGN system

Generally, NGN was built and provided by service providers

With other businesses can build their own system of NGN-based NGN service providers:

+ Step 1: Select a service provider (VPN, beginning of 1800, 1900 ...)
+ Step 2: registration services
+ Step 3: To build own business SoftSwitch-based NGN Carrier
+ Step 4: building applications on the platform there (inter-site connections, conference ...)

 

The order to build an NGN system for businesses focused primarily on building the heart of the NGN system - that's Softswitch

a. Softswitch is available
Advantages:

+ Easy to choose, easy to deploy
+ There is direct support of the company goes wrong
+ Warranty good

 

> Disadvantages:

+ Royalty fee for each application
+ Expand the number of agent or used to buy time cost extension

 

Deployment:

+ Step 1: Select the appropriate system
+ Step 2: install and configure connected devices and other applications available on the NGN

 

b. Softswitch build
Advantages:

+ Customized system configuration
+ Easy to upgrade hardware configuration

 

Disadvantages:

+ Required expertise
+ The setup is capablse of system integration.

 

Deployment:

+ Step 1: choose the server configuration compatible
+ Step 2: install the operating system and application software for making Softswitch
+ Step 3: install and configure connected devices and other applications available on the NGN
