Abstract:
Online Charging System (OCS) uses credit pre-reservation to rating prepaid services. As the current standardized protocols present some problem during the pre-reservation phase, a new service must be introduced to address this kind of problem. In this paper, we propose a protocol for the communication between OCS modules. Running at the application layer, the protocol focuses on the definition of Refuse message, by regarding the credit reservation for call service, to be used when Rating Function module has some performance problem. We formalize the protocol messages and present its design rules and procedures. As results, the protocol was implemented into production in a carrier, and all calls were completed after the new feature.
