This service concept is based on: ! the integration of mobile communications and Internet technologies which will bring the power and richness of Internet services to the mobile environment and ! the interoperability between fixed and mobile networks which will allow users to experience seamless converged services. 44 IP-based multimedia services (2) UMTS Forum This service concept will: ! deliver deliver IP-based, IP-based, real-time, real-time, person-to-person, person-to-person, multimedia multimedia communications communications (including (including voice) voice) ! fully fully integrate integrate real-time, real-time, person-to-person person-to-person with with non non real-time, real-time, person-to-machine person-to-machine multimedia multimedia communications, communications, ! provide provide the the ability ability for for different different services services and and applications applications to to interact, interact, and and ! allow allow the the user user to to set set up up very very easily easily multiple multiple services services in in aa single single session session or or multiple multiple simultaneous simultaneous synchronised synchronised sessions. sessions. The IP Multimedia Subsystem (IMS) and its equivalent in 3GPP2 are elements of 3G technology which will deliver this service concept to our customers 55 The IMS services concept UMTS Forum The IMS Services Concept non-IMS -enabled fixed terminal with E.164 addressing PSTN/ISDN Non -IMS -enabled mobile terminal (e.g., GPRS) Other PLMNs IMS -enabled mobile terminal with IPv6 addressing Fixed Internet IMS -enabled Mobile Networks IMS -Enabled Mobile content IMS -enabled fixed terminal with dynamic IPv4 addressing Interoperability between Networks PSTN Terminal Fixed Internet Terminal Non -IMS Enabled Mobile 66 Key IMS features UMTS Forum Features Comments Real-time, person-toperson, multimedia IMS will have the ability to deliver enhanced speech telephony services (including videophone) using packet technology Real-time and non realtime services interaction IMS allows for interaction of real-time and non real-time services within a single session (call) Multimedia call model IMS allows simultaneous use of: ! Multiple multimedia services within a single session ! Multiple sessions between multiple users and devices The user perceives this as service integration Network interoperability IMS includes the ability for real-time, personto-person communications, including exchanging presence and location information, with other IP networks. 77 Operator advantages UMTS Forum Network deployment and operations !

More recent consumer interest in video technology has fostered the introduction and growth of video services. ! Instant messaging “video chat” services (often available at no charge on the Internet) using Web cameras ! Mobile videophone services for both real-time and streaming video The addition of mobility and presence to the videophone concept has renewed market hopes for a commercially viable consumer service. 99 Benefits of mobility and presence UMTS Forum Benefits of mobility Description Further field of vision Since the camera is mobile, it can be pointed wherever the user desires Expanded use in time and place Mobile Videophone Service would be accessible from any place within the mobile operator service area Benefits of presence Description Increased control Presence allows the called parties to decide when and how they will accept a video call. 10 10 Additional benefits of IMS UMTS Forum Benefits Description Further expanded use in time and place With IMS the service would be accessible from any place within the mobile operator service area and to other networks. In addition, it is possible to exchange media elements between mobile and fixed Internet environments. Increased interpersonal connection through terminal interoperability and integration of services The use of SIP and other existing Internet and video standards will enable increased interoperability between different terminal types. Greater integration of services creates a more natural personal experience. Guaranteed call completion Call completion does not depend on the called party having a compatible terminal. Calls can be accepted without the video component, or the video component can be routed to a different destination. 11 11 Mobile Videophone service (without IMS): user experience Lunch with Ana?
