Next Generation IN Systems


Intelligent Network (IN) is an architecture that allows a communications service provider to deploy and add new services to its wired/wireless communication network without changing other devices and systems. With this IN system, communications service providers can easily and quickly implement additional services (e.g. converting a call, blocking incoming calls, and checking incoming calls not received) and various plans (e.g. plan by age group, promotion plan, and location-based plan) without affecting other core network systems.

Online Charging System (OCS) is a real time billing system for 3G/LTE communication service users, defined by 3GPP international standards. OCS is the advanced system to provide an unified rating both postpaid and prepaid service. UANGEL’s OCS system provides a flexible, real-time, and integrated prepaid / deferred billing function and a flexible scalability, deploying an IMS service provider’s various plan requirements and marketing promotions in an easier and faster way.
