Abstract

The IP (Internet Protocol) multimedia core network (IM CN) subsystem enables PLMN (Private Land Mobile Network) operators to offer their subscribers multimedia services based on and built upon Internet applications, services and protocols. The IM CN subsystem enables the convergence of and the access to voice, video, messaging, data and web-based technologies for the wireless user and it combines the growth of the Internet with the growth in mobile communications. Fig. 1 presents the architecture of the UMTS Release 5 Internet Multimedia Subsystem (IMS) of 3GPP. An example of an IMS architecture is shown in Fig. 2. The multimedia services offered within the IM CN subsystem are not standardized. The intention is that such services will be developed by PLMN operators and other third party suppliers including those in the Internet space using the mechanisms provided by the Internet and the IM CN subsystem. Some of the key applications offered on the IMS will be Presence, Instant Message, Voice Instant Message, Chat, Peer-to-Peer Gaming, Push-to-Talk and Push-to-Video. Of these, Push-to-Talk (PTT) and Push-to-Video (PTV) are envisaged to be the great applications on IMS. Push-to-Video allows multiple users to share live video in real time. Evolved from Push-To-Talk, PTV lets users select people to share live video with, and transmitting an audio/video feed in real time. But for IMS networks to be profitable, it needs not a couple but many more great applications. This text presents a new application framework on IMS called iShare, which may be the next great application on IMS.

The IP (Internet Protocol) multimedia core network (IM CN) subsystem enables PLMN (Private Land Mobile Network) operators to offer their subscribers multimedia services based on and built upon Internet applications, services and protocols. The IM CN subsystem enables the convergence of and the access to voice, video, messaging, data and web-based technologies for the wireless user and it combines the growth of the Internet with the growth in mobile communications. Fig. 1 presents the architecture of the UMTS Release 5 Internet Multimedia Subsystem (IMS) of 3GPP. An example of an IMS architecture is shown in Fig. 2.

The multimedia services offered within the IM CN subsystem are not standardized. The intention is that such services will be developed by PLMN operators and other third party suppliers including those in the Internet space using the mechanisms provided by the Internet and the IM CN subsystem.

Some of the key applications offered on the IMS will be Presence, Instant Message, Voice Instant Message, Chat, Peer-to-Peer Gaming, Push-to-Talk and Push-to-Video. Of these, Push-to-Talk (PTT) and Push-to-Video (PTV) are envisaged to be the great applications on IMS. Push-to-Video allows multiple users to share live video in real time. Evolved from Push-To-Talk, PTV lets users select people to share live video with, and transmitting an audio/video feed in real time. But for IMS networks to be profitable, it needs not a couple but many more great applications. This text presents a new application framework on IMS called iShare, which may be the next great application on IMS.

iShare allows IMS users to share any data stored on (or connected to) their IMS User Equipments (UEs) with other IMS users. iShare brings to IMS the flexibility traditionally associated only with computers, using GPRS/UMTS as the bearer. iShare opens up new avenues in information sharing, with its unique data share framework. iShare goes beyond just sharing of video or multimedia content. iShare brings the concept of sharing just about "any" data in IMS with the convenience of a Personal Computer (PC). In the paragraphs that follow, the iShare framework and its applications are described.

The iShare concept fits snugly into the IMS architecture. The devices/network elements which play a role in the iShare call flows are:

- IMS User Equipments (UEs)

- HSS (Home Subscriber Server)

- CSCF (Call Session Control Function) and

- iShare Share Broker (iSB) Application Server

The only new face in this list is the new Application Server (AS) - the iShare Share Broker. Figure 3 shows exemplarily the architecture of an IMS with iShare. This broker forms the core of the iShare concept. The functions of this AS are:

- facilitate IMS UEs to share their data

- protect the shared data with authentication and authorization checks

- allow IMS UEs to access shared data for which they are authorized

- cache sh...
