A Study of Cost and Network Efficiency in BICC Signaling Protocol

These BICC protocol is a relay protocol adaptable to ATM and IP based core networks compared to ISUP protocol to TDM networks. Using BICC protocol, multirate bearer traffic such as voice and video can flow in the relay core networks. BICC protocol is standardized as WCDMA circuit switching networks in 3GPP Release 4. There have been a lot of papers and technical memos considering BICC protocol theoretically. However, the implementation and efficiency of BICC networks have not been considered much. KTF is now operating core networks using BICC protocol. In this paper, we describe the background and characteristics of BICC protocol and provide the status of KTF WCDMA core networks using BICC. We intend to show the efficiency of BICC protocol using examples of KTF core networks.
