8.1 Introduction
3GPP was conceived some two to three years ago with the express purpose of accelerating work on mobility. Existing standards organisations such as the ITU-T and ETSI had been successful in producing a vast array of international standards for different technologies; however, the speed with which this was attained was slow, especially when compared to bodies such as the IETF. It therefore remained a target of the mobile industry to produce coherent specifications in a time frame that was ahead of those within the standards industry hence the formation of 3GPP. At the end of 1998 and the beginning of 1999 3GPP formed a group known as OSA, Open Service Access. The purpose of this group was to focus 3GPP's efforts on defining an architecture in support of the virtual home environment (VHE) the need here being to provide mobile users with access to their service offerings irrespective of their position within or outside the home network environment.
8.2 Virtual Home Environment
Virtual home environment is defined as a concept for personal service environment (PSE) portability across network boundaries and between terminals. The concept of the VHE is such that users are consistently presented with the same personalised features, user interface customisation and services in whatever network and whatever terminal (within the capabilities of the terminal and the network), wherever the user may be located. The first specification was known as Release 99. This was seen as a historical separation between networks of...
