Using the Nokia IP Multimedia Pilot System, Nokia successfully illustrates SIP-based services that can operate over both 3GPP and 3GPP2 air interfaces at the CDMA Americas Congress in San Diego, California
Today at the CDMA Development Group (CDG) conference, Nokia demonstrated advanced person-to-person IP mobility services using the Nokia IP Multimedia pilot system, which provides standardized IP Multimedia Subsystem (IMS) functionality. Nokia's IMS pilot system supports both 3GPP2 and 3GPP air interfaces, and is an extension of services first demonstrated by Nokia in February 2002 at the 3GSM World Congress in Cannes.
The demonstration is a major milestone in the ongoing efforts to achieve mobility services convergence between 3GPP and 3GPP2 based networks. Mobility services convergence has received a significant boost this year with the push in the standardization bodies for unification of the IMS between 3GPP and 3GPP2. Nokia is actively participating in 3GPP and 3GPP2 to further these efforts, and this demonstration reinforces the key role of the IMS in achieving services convergence.
The IMS enables person-to-person IP connections between terminals, which will give rise to many new multimedia services. IMS allows operators to go beyond current person-to-content services such as browsing and content downloading, to provide new person-to-person services, including interactive gaming, "see what I see video telephony" services, and end-to-end simultaneous voice, video and chat sessions between terminals.
The first commercial release of Nokia's IMS core network infrastructure is expected in 2003, followed by IMS capable terminals in 2004. Standardization of the IMS is a key component that will enable rich sessions and generate additional traffic and revenue for operators. A single converged IMS standard provides multiple benefits for the mobile industry, which help fuel mass-market adoption of SIP-based services. For example, terminal interoperability, user reachability, flexible charging methods, reduced industry fragmentation, and a single standard focus for the application development community.
"Nokia is a strong advocate of open, standardized systems. With this demonstration, Nokia is clearly showing the potential for exciting new SIP-based services, as well as the services convergence between 3GPP2 and 3GPP networks that is possible using the IMS," says Juha Akras, Vice President, Nokia Networks. "Nokia is creating IMS products that will lead the industry to access-independent services. We intend to continue aggressive 3GPP2-3GPP IMS unification in the standards bodies to enable the benefits of a single standard for the mobile industry."
"SIP based services, as demonstrated through the IMS, enable exciting new applications across various access technologies, and is a key element in the rollout of future high speed data protocols such as HSDPA and 1xEV-DV," said Adam Gould, CDMA Chief Technology Officer, Nokia Mobile Phones. "Nokia is firmly committed to open standards such as IMS, and industry initiatives such as the Open Mobile Alliance. It is with this commitment that we are able to continue delivering innovative handsets supporting both OMA and SIP capabilities in CDMA."
