This paper addresses the capability needed in a telecommunication system to support mobile access to real-time sights and sounds of a complex environment defined as a virtual reality service (VRS) episode. The constant growth in data transmission rates and the innovative advances in the development of terminal and networking equipment are paving the way for the provision of a VRS and the creation of VRS episodes in the near future. These advancements are necessary for transmitting, transporting, and receiving data at super-high transmission rates for establishing VRS episodes. This paper describes a mobile VRS environment in general and the core architecture and describes the various entities employed to perform a VRS episode setup task. The proposed VRS architecture is in full harmony with preceding generations of all-IP multimedia networks currently under study in the 3rd Generation Partnership Project (3GPP), the 3rd Generation Partnership Project 2 (3GPP2), and the International Telecommunication Union (ITU).
