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

PROBLEM STATEMENT

• 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

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).

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

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.

VRS IMPLIMENTATION SCENARIO

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

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
