Ericsson, Huawei and Nokia have signed an extended MoU on OSS interoperability initiative(OSSii) to include additional scope to the original framework. The OSSii was started in May 2013 with the objectives of enabling ad simplifying interoperability between OSS systems, reducing overall OSS integration costs and enabling shorter time-to-market.
The new MoU adds Management and Orchestration (MANO) interfaces and IP Multimedia Subsystem (IMS) domains to the original agreement.
MANO is an ETSI-defined framework for the management and orchestration of resources in a cloud data center. IMS is a core network solution that delivers rich real-time communication services such as HD voice and Wi-Fi calling, for consumer and business users over any access network and for any device type.
