OCS is for securing real-time charging payments
Leissner OCS is a core system for real-time online charging of data, voice and messaging services. Each service can be charged according to a price plan or consumed per unit from a volume. Subscribers, price plans and buckets are provisioned through a web service. Leissner OCS is an essential component for a mobile operator or an MVNO in order to provide mobile services with real-time billing. The online functionality improves fraud prevention and complements the service provider’s legacy systems for fraud control. Leissner OCS has carrier grade redundancy and is designed to be installed on virtual servers with Linux operating system.
OSC is a part of a complete suite of mobile core components in Leissner MVNE/MVNO Mobile Core. This suite of flexible functionality empowers MVNO and MVNEs to stay ahead of competition and gives low TCO (Total Cost of Ownership).
Leissner OCS is flexible and can be customized for different telecom operators’ needs including niche segments and selected use cases such as roaming data or voice control. The OCS system consists of three Leissner nodes: CCA, gsmSCF and Diameter Server.
