What is OSSii?

OSSii – Operations Support Systems interoperability initiative was initiated in May 2013 to enable OSS interoperability between different OSS vendor’s equipment. OSSii Overview material can be viewed here. Operations Support Systems integrate to a variety of telecom network technologies from several equipment vendors as well as the telecom operator business systems, making the integration of OSS a complex and costly. The objectives of OSSii include enabling easier interoperability between OSS systems, reducing overall OSS integration costs and enabling shorter time-to-market. OSSii – Operations Support Systems interoperability initiative has Ericsson, Huawei and Nokia as initiating parties. OSSii is built on a set of principles – openness, fairness, reasonableness and non-discriminatory treatment – all expressed in the Memorandum of Understanding (MoU) between the Intiating Parties. The renewed MoU from Feb 18th, 2019 can be read here.
