ZTE Showcases World’s First VoLTE Call Based on IMS with Existing Mobile Networks at Mobile Asia Congress 2010

    ZTE Corporation, a leading global provider of telecommunications equipment and network solutions, demonstrated successful IMS based Voice over LTE (VoLTE) calls on CSL Limited (CSL)’s LTE network and its existing mobile networks at Mobile Asia Congress 2010 (MAC 2010). The calls finished between IMS clients as well as IMS client and conventional
2G/3G handsets. This is the first time VoLTE calls are made to the industry based on the inter-operability of LTE network and existing 2G/3G networks. In addition, supplementary services such as call forwarding, call waiting were demonstrated.

    VoLTE is the next step in developing a standard way of delivering voice for LTE. Through the use of its IMS-based solutions and LTE expertise, ZTE is able to demonstrate how voice will work seamlessly in the future. The successful VoLTE showcase at MAC 2010 builds on the deep relations between ZTE and CSL. In July this year, ZTE and CSL began deployment of the world’s first 1800 MHz/2600 MHz dual-band LTE network as well as the upgrade of
CSL’s existing 3G network with Dual Cell technology. The dual-band LTE network takes advantage of CSL’s spectrum position to provide customers with better coverage and enhanced penetration, for a more satisfying communications experience. CSL is one of the first operators in the world to introduce LTE technology into its network infrastructure.

    ZTE provided Uni-CORE solutions for CSL to build an intelligent, convergent and high-performance core network, achieving 2G/3G/4G full convergence. CSL’s network will support accurate service control and content-based billing. It provides powerful data throughput to ensure that the network can deal with the challenges from the explosive growth of data traffic as well as an increasingly complex services.

    ZTE is the provider of core network equipment and solutions supporting all access technologies. ZTE’s all-IP Uni-CORE solutions cover fixed network softswitch, mobile softswitch and IMS. Recently, ZTE launched its IMS-based zMILE (ZTE’s Multimedia Integrated Life Experience) solution, including IMS core network, RCS-compliant APP, and the 7 inch touch-screen ZTE Light multimedia tablet terminal with inbuilt an IMS client. The zMILE solution is a carrier-class multimedia solution, enabling a breakthrough in delivering a true multimedia experience to legacy end users over fixed and/or mobile networks, including LTE network. As of Q3 2010, ZTE core network globally served 1.34 billion subscribers around 110 countries. (ZTE Corporation)
