NGN

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

Through the separation of service and call control, the service- independent architecture is implemented, which makes services independent of switching network.

NGN provides integration of voice, data, fax, and video services.

NGN (Contd)

In broad sense it refers to the next generation integrated network that adopts new technologies extensively, focuses on IP, and provides voice, data, and multimedia service at the same time.

In narrow sense it refers to the open system structure that employs soft switch at the control layer.

SOFT SWITCH (SOFTX 3000)

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.

• UMG8900 supports inter-working between different bearer networks and provides conversion function between different traffic flow formats:

– UMG8900 can server as Trunk Gateway (TG);

– Act As Access Gateway (AG) in NGN network;

– Support Embedded Signaling Gateway (SG) function simultaneously.

• By networking with soft switching devices, UMG8900 can act as next-generation TDM switch adopting next-generation (NGN) architecture to provide all services of PSTN and achieve smooth evolvement to NGN.

UMG 8900 Functionality Features

14

• UMG8900 serves as TG or AG in NGN or as the traditional PSTN switch and the next-generation switch.

• In NGN, UMG8900 is applied in the gateway exchange and toll exchange as large-capacity TG.

• Through the combined networking with soft switching device , UMG8900 can provide next-generation TDM switch application.

• MG8900 can act as tandem exchange / toll office / gateway exchange / C5 networking application of PSTN to implement the seamless evolution to NGN.

• Provides AG function of large capacity via RSP user frame of UMG8900 accesses user directly.

Ongoing Issues

• NGN status is currently under PAT• PAT of Softx 3000, UMG 8900,SG 7000 & MRS

has been completed. Discrepancy list comprising of Non Service affecting & some deficient features has already been forwarded to the vendor through Dig Dev wing.

• Connectivity with some UMG’s is still pending due to Media/hardware unavailability at the far end (LX side).

• Extension of NGN NMS room is required. Several civil works need to be done.
