NEC PROVIDES BILLING GATEWAY FOR DOCOMO'S STANDALONE 5G SYSTEM
CGF enables efficient billing by organizing data and linking it to the system.
NEC Corporation has provided NTT DOCOMO, INC. with a Charging Gateway Function (CGF) for high-performance processing of billing information, which is becoming increasingly complex due to the growing sophistication of service menus. The CGF began operating in December 2022 as a gateway-packaged product that connects DOCOMO's existing standalone 5G mobile core network (SA 5GC).
Service menus utilizing 5G are becoming more diverse, and the development of new services beyond packet communications, SMS and voice communications is expected to continue advancing in the future. For this reason, telecommunications carriers are demanding packaged products that can flexibly support new services. However, when using a packaged product for a gateway, it is necessary to develop connections for the parts of the system where information such as BSS is linked. Therefore, building a new gateway requires excellent packaged products and know-how in the development of connection systems.
Based on this background, as an advanced initiative in the industry, NEC has introduced a CGF packaged product at the request of DOCOMO.
Features of this initiative include:
- Efficient billing processing with CGF packaged products
- Flexible support for new services and scalability through online processing of billing information
- Making use of NEC's track record in system development for telecommunications carriers to achieve connectivity while minimizing the development of external systems
NEC will continue to leverage this track record to provide 5G networking, BSS, and operation support systems (OSS) to telecommunications carriers as comprehensive high-quality solutions, helping them to quickly launch new services, streamline operations, and improve revenue.
