1  Scopep. 5

The present document specifies the content of the Stage 1 requirement for realisation of VHE.
Virtual Home Environment (VHE) is defined as a concept for Personal Service Environment (PSE) portability across network boundaries and between terminals. The concept of 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.

3  Definitions and abbreviationsp. 6

3.1  Definitionsp. 6

For the purposes of the present document, the following terms and definitions apply:
HE Services:
services, which are provided by the home environment
Home Environment Value Added Service Provider. This is a VASP that has an agreement with the Home Environment to provide services. The Home Environment provides services to the user in a managed way, possibly by collaborating with HE-VASPs, but this is transparent to the user. The same service could be provided by more than one HE-VASP and each HE-VASP can provide more than one service.
Home Environment:
responsible for overall provision and control of the Personal Service Environment of its subscribers.
Local Service:
See definition in [1].
are not standardised and could be implemented at the PLMN entities (e.g. HLR) on a vendor specific basis or using toolkits (CAMEL, USAT, MExE). These tool-kits use standardised interfaces to the underlying network (e.g. CAP, MAP) or use Bearers to transport data, for example, from the MExE service environment of USAT server to the UE/USIM. The implementation of these operator specific services on the different platforms (CSE, MExE service environment or USAT Server, UEs) is done in a completely vendor specific way and uses only proprietary interfaces.
Personal Service Environment:
contains personalised information defining how subscribed services are provided and presented towards the user. Each subscriber of the Home Environment has her own Personal Service Environment. The Personal Service Environment is defined in terms of one or more User Profiles.
set of functions offered to a user by an organisation.
Service Toolkits :
bearers defined by parameters, and/or mechanisms needed to realise services.
Standardised services:
standardised services (Supplementary Services, Tele-Services, etc.) are implemented on existing PLMN entities (e.g. HLR , MSC/VLR and terminal) on a vendor specific basis, using standardised interfaces (MAP, etc.) for service communication (e.g. downloading of service data). Availability and maintenance of these Services is also vendor dependent.
is a logical entity, which uses PLMN services.
User Services Profile:
contains identification of subscriber services, their status and reference to service preferences. This is part of the User profile information.
User Profile:
A set of information necessary to provide a user with a consistent, personalised service environment, irrespective of the user location or the terminal used (within the limitations of the terminal and the serving network). The user can define one or more User Profiles according to the user's needs. The user's Home Environment manages the User Profile(s).
Value Added Service Provider:
provides services other than basic telecommunications service for which additional charges may be incurred. The user may access services directly from Value Added Service Providers and the serving network. The Home Environment does not support services obtained directly from VASPs or serving network outside home network. VASP has no service agreement with the Home Environment.
Virtual Home Environment:
concept for personal service environment portability across network boundaries and between terminals.
Further definitions are given in [5].
