Netcracker, an NEC subsidiary, has provided a Charging Gateway Function (CGF) for high- performance processing of billing information for NTT DOCOMO.
The CGF began operating in December 2022 as a gateway-packaged product that connects DOCOMO's existing standalone 5G mobile core network (SA 5GC), which was provided by NEC, to its business support system (BSS) for customer administration and billing.
Netcracker built the solution using DigitalRoute's product for high traffic processing to achieve efficient billing. DigitalRoute's CGF packaged products have been deployed at more than 400 businesses around the world and comply with international standards (3GPP). The CGF can organize large amounts of billing information generated for each service, such as packet communications and voice calls, and link it to the BSS for efficient billing processing. Netcracker has extensive global experience implementing solutions based on the DigitalRoute product suite and was instrumental in its implementation at NTT DOCOMO, working closely with NEC as the system integrator and DigitalRoute as the product vendor.
"NEC is proud to have provided DOCOMO with this total 5GC system featuring CGF. We have a long history of collaboration with DOCOMO spanning a wide variety of solutions, and we look forward to continuing the provision of high-quality, highly reliable end-to-end networking solutions in the future," said Michio Kiuchi, Senior Vice President, NEC Corporation.
