What is NGN What is NGN

Next Generation Network (NGN) is a service-oriented network.

Through the separation of service and call control, as well as

call control and bearer, the service-independent architecture is

implemented, which makes services independent of network.

NGN is a kind of open and integrated network architecture.

NGN is a kind of brand-new network integrating voice, data, fax,

and video services.

SummarySummary

NGN is divided into four layers: access layer, transport layer, contr

ol layer and service layer.

NGN is the four-layer hierarchical network based on packet switchi

ng and transmission. Interworking between different layers is realiz

ed via open standard protocols, which provides NGN with consider

able advantages and flexibility.

Located at the control layer of NGN, SoftX3000 is the core control e

quipment in NGN for information interchange. It is used to control t

he communication of various MGWs.

The transmission and interchange of information streams between

MGWs do not fall into the control of SoftX3000. It is under the contr

ol of transport layer instead.
