Telstra, Australia's largest mobile operator, has selected the Ericsson diameter signalling controller (DSC) to expand its wireless network and meet the rapid growth in mobile broadband usage
Control signalling is probably the most critical function in a telecom network and diameter has quickly become one of the most widespread protocols. By incorporating DSC, Telstra shows its commitment to continue to evolve to the next-generation all-IP network, meeting the exponential growth in smartphone-driven traffic
As more and more operators deploy LTE the requirements for signalling control, both within an operator's own network and between operators, also increase
The benefits of implementing Ericsson DSC include more robust signalling network architecture, significant CAPEX and OPEX savings, and a reduced risk of malicious IP attacks, the company claimed
It will also improve the use networks during peak traffic times, through load balancing and overload protection mechanisms. These improvements will help to protect against any potential network element failures
David Robertson, director transport and routing engineering, Telstra said: "Networks are evolving from narrowband signalling to diameter signalling, and we are leading the adoption of this new signalling architecture. DSC provides a more resilient mobile broadband network. We are deploying this technology to ensure we are ahead of the curve with growth in traffic complexity while delivering superior network performance to our customers.
Håkan Eriksson, head of Australia and New Zealand, Ericsson said: "Telstra's selection of Ericsson for this key piece of core network infrastructure demonstrates confidence in our technology and commitment to our strategic partnership in wireless core and LTE.
Ericsson diameter signalling controller is implemented on Ericsson Blade System, a scalable, high-capacity platform that is involved in some 40% of the world's total voice and data traffic. It can be deployed as a stand-alone node, or co-located with Ericsson products such as IP-signalling transfer ooint, session border gateway and service-aware policy controller.
Furthermore it is complemented with a selection of Ericsson services delivered by certified consultants who have extensive experience with systems integration.
