Abstract

Indonesian cellular operators have deployed Long Term Evolution (LTE) technology to improve data services to users. To provide voice service, LTE operators introduce Voice over LTE (VoLTE) with better quality than Voice over IP (VoIP) service because it has low latency and larger capacity. VoLTE technology with an IP Multimedia Subsystem (IMS) platform is an IP based technology that will work best when interconnecting between IP telecommunication operators using IP protocols such as SIP or SIP-I session protocol. Currently, interconnection of telecommunication operators in Indonesia is sti ll time-based division multiplexing (TDM) interconnection. This research will discuss mobile operator infrastructure readiness to migrate interconnection from TDM-based network to IP and will calculate bandwidth requirement for IP interconnection network. With data from XL Axiata operator it was found that IP interconnection caused a decrease in bandwidth requirements of XL Axiata operator compared when using TDM-based interconnects. The value of bandwidth requirement reduction is strongly influenced by the type of codec used. It appears that the G.723 codec provides significant bandwidth reduction but has a low mean opinion score (MOS).
