The IBCF (Interconnection Border Control Function) performs border controller roles between networks in IMS network interlocking, and handles security and interlocking related issues in interlocking with various networks.
As an IMS NE performing interlocking contact between domains of the IMS system, IBCF not only provides IMS calls handling signaling and member media handling for inter-IMS operators’ interlocking, but also provides security, NAT Traversal, protocol transformation handling, and IP version interlocking function between different systems of differing IP versions as well as between a terminal and system.
