  3. INTRODUCTION • A mobile virtual reality service (VRS) will make the presence and presentation of the sounds and sights of an actual physical environment virtually available everywhere in real time • VRS is the conversion of a physical system into its digital representation in a 3D multimedia format. • multimedia environment to its virtual presence everywhere in real time . • VRS do not allow user control in viewing 3D environment’s & generally limited to viewing images on monitor in 2D

  4. From a users perspective, the VRS is defined as the experience of viewing an object in its 3D environment and sensing its sound with its natural and real-world quality A virtual movie theaters where a user can view movies with the same feel as being in a movie theater. A virtual conference session depicting to every participant the presences of others in a virtual conference room with projector screen, drawing board, and so on The VRS will include both terminal and personal mobility. It could be a set up in a limousine, hotel, airport, home or office PROBLEM STATEMENT

  5. A schematic view of VRS functional Architecture

  6. SOLUTIONS The VRS realization scheme is built upon the development and availability of the following entities: • Actual physical environment (APE) • VRS user equipment (VUE) • VRS access system (VAS) and • VRS core system (VCS).

  7. VRSepisode setup information flow diagram.

  8. VRS EPISODE SETUP SIGNALINGINFORMATION FLOWS • Initiating the request for establishing a VRS episode • Recoganising the request for establishing a VRS episode • Sends n information query to VUE • Recoganising the request for establishing a VRS episode • Using information on the VUE’s VRSinformation • VRS have been identified AND\OR alerted • SVECE forward the episode response • All necessary notification have been received

  9. VRS EPISODE SET UP

  10. GATEWAY ENTITY • The gate way entity is a bountry function entity with each VCS .it is the connection point of all VCES in a VCS network from one side & the GWE of another VCS frome the other side.

  11. VRS IMPLIMENTATION SCENARIO • This section presents an example of VRS architecture ,a configuration scenario for single VUE &multiple APES participating in a VRS episode

  12. DISADVANTAGES • Currently the availability of VRS is limited to fixed applications such as entertainment, machines & flight simulator • Lack of VRS capable user terminal equipment • Inadequate data transmission rates over the air • Absence of efficient and suitable signaling 7 controlling network

  13. REFFERENCE • www.interscience.wiley.com • IEEE Journal 2000. • M .Grech,M.torabi,and M. Unmehopa , “service control architecture in the UMTS IP Multimedia core network subsystem”. • P.Mitra , M.Andrews, and R.de carvalho, Tripling wireless capacity, Bell labs news.
