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 packetswitched 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 throughthe open network adopting distributed standard protocols.
