GMI successfully tests end-to-end WiMAX and IMS

ZTE is boasting of its participation in the GMI 2008 (Global MSF Interoperability) event held by the MSF (MultiService Forum) to advance the development of next generation networks (NGN).

GMI 2008 is a worldwide multi-vendor interoperability test environment organised by the MSF, where next-generation network elements are verified in practical scenarios. The tests aim to provide equipment vendors with the opportunity to validate key service concepts that leverage an IMS/NGN infrastructure. Verification trials took place from October 20-31, spanning several worldwide locations that include the US, UK and China.

ZTE provided equipment to the test sites of operators located in UK, China and USA, working with the operators and participating vendors to verify end-to-end WiMAX plus IMS, IPTV and TD-SCDMA technologies in six network test scenarios defined by the MSF.

The tests focused on ZTE's end-to-end WiMAX plus IMS system, including WiMAX Macro and Pico cells and an IMS core network. With this system, ZTE demonstrated interoperability with other vendors' IMS core network solutions, as well as various access technologies, such as WiMAX, broadband, 3GPP2 and 3GPP - including Chinese-developed technology TD-SCDMA. The tests involved various scenarios, including VoIP, roaming, IMS-based IPTV and location-based services.

ZTE provided the converged resource control platform, ZXUN RCP- the only QoS equipment that supports both the Policy and Charging Control (PCC) and Resource and Admission Control Subsystem (RACS) architectures defined by 3GPP and TISPAN respectively - successfully completing the verification of dynamic QoS scenarios.
