5G Binding SupportFunction (BSF) Data sheet

The Binding Support Function (BSF) is one of the key functions of the 3GPP Service-Based Architecture (SBA) for 5G Core networks. It enables other Network Functions (NFs), for example an IMS Call State Control Function (CSCF) or Network Exposure Functions (NEF), to determine which Policy Control Function (PCF) is holding needed Policy & Accounting information for each active Mobile device Data Session.

NetNumber’s BSF also provides Diameter Gateway functionality used to interwork 4G Diameter requests in order to retrieve the PCF Diameter host used in support of dual-binding & 4G / 5G handover cases.

The BSF solution is built on NetNumber’s all new TITAN.IUM, Cloud-Native, InterGENerationalTM platform providing “deploy anywhere” flexibility and secure management.
