What is NGN

Next Generation Network (NGN) is a service-oriented

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.

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.

Introduction

As a SoftSwitch product, SoftX3000 is located at the core

control layer of NGN scheme.

SoftX3000 acts as a generic Call Controller in the packet-

switched network, supports the interworking between PSTN,

H.323, SIP, and MGCP domains.

SoftX3000 provides H.248 and MGCP based bearer control.

In the NGN solution of Huawei, SoftX3000 acts as the core

of NGN, interworking with other NGN components through

the open network adopting distributed standard protocols.
