OSS-RC Operations Support System –

Radio and Core

OSS-RC is the main product for GSM and WCDMA radio and core network

management. It supports centralized operation and maintenance of 2G and

3G networks. The 3G O&M solution provides end-to-end management of the

radio, core, and backbone networks. It provides a common framework for

handling of nodes within those networks.
