MWC 2015: ZTE SDN demo launched at Mobile World Congress

Company claims its SDN solution is set to reduce IP RAN network operation and maintenance manpower cost by 30%; ZTE also contributes to next-generation Softnet Architecture for Mobile with iSDN solution

MWC 2015: ZTE SDN demo launched at Mobile World Congress

ZTE Corporation launched its IP radio access network (RAN) operation and maintenance (OAM) system based on elastic software defined networking (SDN) technology at Mobile World Congress today (5 March 2015). 

This network enables the system to implement unified management on IP RAN via the SDN controller. 90% of routine OAM work can be performed with one-touch operation on mobile terminals, which can save at-least 30% in manpower costs, ZTE claims. 

The company added that its solution of introducing SDN technology to an IP RAN OAM to effectively reduce OAM cost has generated widespread attention among the operator community. 

This is the first time ZTE’s IP RAN SDN technology has been demonstrated and talked about publicly. At the show, the solution attracted significant interest, specifically around the new OAM mode, which includes zero configuration and plug-and-play functions of the equipment, one-touch service deployment and automatic service path protection. 

The sharp increase of mobile data demand has resulted in global mobile operators working hard to deploy 4G networks to ease the ever increasing mobile data traffic on the network. The result is the IP RAN mobile bearer network facing significant management pressure. 

Consequently, operators are focussed on how to cope with the impact of data traffic, effectively manage IP RAN and further reduce the high OAM costs. ZTE’s elastic IP RAN SDN solution effectively solves the problem by introducing SDN architecture and adopting virtualisation technology, it performs unified management on access layer and aggregation layer equipment using an SDN controller. 

The plug-and-play capability of equipment and one-touch service deployment enables 90% of the OAM work to be completed with one button, greatly reducing OAM workload and simplifying OAM complexity. 

The simultaneously released PC version, portable application description (PAD) version and mobile phone app enables users to perform network OAM out of the equipment room and complete 90% of routine OAM work using mobile terminals.

ZTE contributes to next-generation Softnet Architecture for Mobile with iSDN solution

 ZTE also announced today that it has collaborated with China Mobile to jointly provide an integrated software defined networking (iSDN) solution to the next-generation Softnet Architecture for Mobile (SAME). This solution, which uses a mobile network architecture based on NFV and SDN technologies, will enhance the efficiency and flexibility of mobile networks in the future.

Through SDN-based packet gateways, the SAME solution separates the signaling processing module on the control plane from the basic-packet forwarding module and the complex-packet value-added processing module on the user plane, allowing for the centralised deployment of modules on the control plane and distributed deployment of the basic-packet forwarding module on the user plane. 

Using service chain technology, the solution optimises user plane performance, saves device costs, guarantees a smooth user experience and provides operators and terminal users with efficient, flexible, and reliable networks.

In terms of network virtualisation and SDN, ZTE provides industry-leading manageable and integrated Cloud UniCore solutions with high cost-efficiency and carrier-class security, covering all network elements in the Packet Switching (PS) domain, IP Multimedia Subsystem (IMS), User Data Center (UDC), and Circuit Switching (CS) domain of mobile core networks.
