South Korean operator, SK Telecom has deployed Samsung's virtualized IP Multimedia Subsystem (IMS) components of its AdaptiV Core platform to support its LTE-Advanced network. Samsung’s AdaptiV Core platform is designed to combine virtualization of LTE core network elements, such as the Evolved Packet Core (EPC) and IMS, with robust OSS capabilities in the form of the CognitiV Cloud Manager.
The very first virtualized network functions deployed on the AdaptiV vIMS for SK Telecom is the virtual Call Session Control Function (vCSCF), which will be responsible for various VoLTE-related processes including handling call setup, providing billing and policy control, interfacing with 3rd party networks for roaming users, as well as identifying and correctly routing emergency calls. Additional Virtualized IMS Network Functions (IMS VNFs), such as the virtual Access Gateway (vAGW), will be deployed at a later date.
The deployment of the AdaptiV vIMS solution follows closely SK Telecom’s deployment of Samsung’s AdaptiV vEPC in early August, and represents a concerted effort by the two companies to explore the capabilities and advantages of NFV. Samsung and SK Telecom also recently announced a proof of concept for Software Defined Networking technology, scheduled for later this year, in the operator’s core network.
