Challenge
To advance its strong position in the market, KT sought to provide its customers with innovative Internet Protocol (IP) based services—such as Ring Back Tones, IP Centrex and Multimedia Caller Identification—without incurring tremendous costs supporting a separate IP broadband network.
Solution
A converged network would 1) reduce complexity, 2) optimize KT's existing voice network investment and 3) enable KT to take advantage of evolving technologies for data and multimedia services.
KT implemented HP OpenCall Service Controller to accelerate the development, testing and deployment of wireline, wireless and next-generation services. Utilizing SS7 and IP signaling, the HP OpenCall solution provided KT with a highly scalable platform to ensure quality of service in the converged network.
Because the IN service operation is tightly coupled with HP OpenCall Service Controller, the current staff of operational experts needed little training on the HP OpenCall IP platform. In fact, the existing staff now supports both Intelligent Network (IN) and IP services, significantly reducing total cost of ownership.
KT is now positioned to deliver the full range of services available today and the next-generation IP services of tomorrow. In 2007, KT will upgrade IN services to provide both voice and video capability. In addition, the company will use the HP OpenCall solution to migrate public switched telephone network (PSTN) services to the IP network, expanding capacity accordingly.
