According to a survey by Informa, one of the biggest challenges service providers face when deploying LTE comes from integration problems with legacy networks.
Standards are not enough to mitigate Diameter incompatibilities. 3G-to-LTE roaming necessitates Diameter to SS7 interworking. However, signaling can provide service providers with an amazing option for differentiation.
As the Diameter Signaling Controller (DSC) is central to the IP network, it's also a central hub for services orchestration for not only Diameter, but also SS7, RADIUS and IT apps.
Operators can use services orchestration to remain relevant; signaling offers operators major differentiation opportunities beyond standards. Productized interworking provides the ability to take back control and create services across technologies. The next-generation Diameter Signaling Controller (DSC) will be the central hub for services customization and agility for operators.
