[Taiwan's Chunghwa Telecom launches push-to-talk service using Nokia's Push to talk over Cellular (PoC) solution.]

Espoo, Finland -- Chunghwa Telecom Co., Ltd. has launched Taiwan's first push to talk service, using Nokia's industry-leading Push to talk over Cellular (PoC) solution, marking a major step in Chunghwa's drive to bring its customers next-generation mobile service. Nokia now has commercial PoC network contracts with 18 GSM operators, and is trialing with well over 30 operators worldwide.

Under the agreement, Nokia is providing a complete PoC solution, including system installation and integration. Nokia's PoC solution is in line with the Industry Consortium Pre-standards specification and can be upgraded to the OMA PoC standards, which are expected to be ratified next year.

"Chunghwa Telecom is one of Nokia's leading customers in adopting new technologies," said Simon Beresford-Wylie, Senior Vice President, Networks, Nokia. "Push to talk service is an important milestone in the multimedia arena, and is widely considered to be the lead application using the IP Multimedia Subsystem. We see great promise also in our on-going cooperation with Chunghwa in the area of SIP/IMS technology, and look forward to wider scale pilots of IMS applications in the future."

IMS is the network architecture platform for advanced IP-multimedia services, such as real time video sharing, content sharing, push to talk, and various interactive applications including gaming. IMS also paves way for the introduction of Voice over IP (VoIP), a key part of the convergence of fixed and mobile domains. It provides the connectivity that enables SIP-capable terminals and devices to establish IP sessions between each other, over any IP connection, such as GPRS, WCDMA 3G, broadband home connections or WLAN hotspots.
