ETSI 6 ETSI EG 201 71 7 V1.4.3 (2000-01) 1 Scope The present document covers scenarios and procedures to support the UMTS Virtual Ho
17、me Environment (VHE). The Virtual Home Environment is a capability for providing operator-specific services to end users with a consistent look and feel which is independent of location and serving network. It facilitates service adaptation to different network environments supporting directly conne
18、cted, cordless and cellular access. The philosophy of VHE has been proposed by GSM MOU and implementation scenarios have been identified and studied by ITU-T for IMT-2000 work. 2 Ref e ren ces The following documents contain provisions which, through reference in this text, constitute provisions of

23、etwork boundaries and between terminals. The concept of the VHE is such that UMTS users are consistently presented with the same personalized features, user interface capabilities and services in whatever network and whatever terminal, whereever the user may be located. The exact configuration avail
24、able to the user at any instant will be dependent upon the capabilities of the USIM, Terminal Equipment and Network currently being used or on the subscription restriction (user roaming being restricted) ETSI 7 ETSI EG 201 71 7 V1.4.3 (2000-01) 3.2 Abbreviations For the purposes of the present docum

30、ironment supports: service transparency: between different IMT-2000 networks; transparent execution: of the “Virtual Home Environment“ service features: the VHE service features are used by mobile operators to provide more functionality to mobile users than basic mobility. The services may be execut
31、ed without necessary sharing of service and subscriber information with the visited mobile operator (except of roaming agreements); customized services: the means for network operators, service providers and users to define their own specific featuredservice; a personalized service set: with user pe
32、rsonalization of features/services; service level: it is desirable that the roaming mobile end-users will experience the same service level as within their home networks (the Virtual Home Environment concept). Therefore, it is desirable that services are provided transparently by the visited network
33、s; provisioning of subscriber specific services: mobile users may have custom demands for functionality from their home service providers. The Virtual Home Environment intends to make management access to customized services available to mobile users when roaming; limited network load: the current m
34、obile networks already manage a considerable signalling load to handle a mobile call. This signalling is required to maintain the mobility information of the mobile subscriber up to date. Therefore, the signalling load of new features must be limited as far as possible to ensure that the mobile netw
35、orks signalling capacity will not be overloaded; activation of mobile related call events; perform charging activities: the VHE may be able to exchange charging parameters between the Home Service Provider and Serving (Visited) Network. This exchange is required to have services such as Advice of Ch
36、arge; perform in-band user interaction: the VHE shall provide the capabilities to order the playing of announcements and tones towards callingkalled subscribers during the call-setup, call disconnection, unsuccessful call establishment, and incoming call procedures; allow for subscriber interaction:
37、 the subscriber should have control capabilities to activatehegisterhnvoke supplementary services. The VHE should be able to add functionality to these supplementary service control mechanisms: interaction with the supplementary services: the mobile network provides a number of supplementary service
38、s; interaction with these services needs to be considered. Structure of the issues for mapping functional modularity The above categories will need to be structured into the following categories. ETSI 9 ETSI EG 201 71 7 V1.4.3 (2000-01) 4.2.1 Applications Applications by their nature are in the open
39、 competitive market and should not be standardized. However, a few widely used applications may benefit from standardization since significant performance advantages may be gained from features having a static distribution. A basic level of standardization may be and has proven useful to made applic
40、ations accessible to the marketplace and simpler to use: e.g. the layout of the telephone and typewriterPC keyboard. Definition of examples is highly useful to understand the implied requirements on the lower layers. 4.2.2 Appl ication support A vast number of technologies are being pursued in this
41、category some of which are being standardized: e.g. the IS0 ECMA-script, based on JAVAscript. Other technologies are being pursued in industry fora: e.g. WTML in the WAP Forum. An initial list of the supporting technologies by which VHE is facilitated is included below: CAMEL (Customized Application
42、 for Mobile Enhanced Logic), INAP SSF-SCF interaction; SIM ToolkitISmart Card applications; WAP (Wireless Application Protocol); MEXE (Mobile application Execution Environment); Internet Protocols Service Negotiation; IP Media Controllers and Gateways; INAP CS3 SCF-SCF secure interaction; Software A
43、gent technologies; Technologies for software download; Distributed Processing/CORBA. It is clear that for these technologies to be transparently supported across networks whilst being recognized at the endpoints (terminals and servers) and in the network access points and gateways some standardizati
44、on is required. It must be noted that that some of the above technologies aim at network independence but all of them are based on a network specific evolution. Some cases imply that the serving network supports knowledge on the service; e.g. CAMEL uses IN triggering. The major challenge for the com
45、puting distributed processing based technologies is the efficiency and speed; it is unlikely that in a competitive world that distributed processing technologies like CORBA will be deployed to interwork throughout global networks. However the software architecture may be deployed on several endpoint
46、s (terminals and servers) with high speed links between these endpoints, thus divorcing the software platform from the underlying physical network. Resource Control in such a scenario is a complex issue of the software requesting resources for handling multiple media streams without having direct co
47、ntrol of knowledge of the configuration of where the resources may be sited. Service Mediation is required in an end-to-end sense when setting up the requested service, however negotiation and fall back procedures require definition where one endpoint fails to maintain the service or an intermediate
48、 transport network cannot support the required resource. ETSI 10 ETSI EG 201 71 7 V1.4.3 (2000-01) 4.2.3 Transport and Sig na1 I i ng capabi I ities Transport and signalling capabilities are required and must be standardized to carry the VHE capabilities; some options exist, including: encapsulated
49、signalling across SS7: Q.gft protocol; Q.sig; INAP CS3 SCF-SCF Service to Service encapsulation; INAP CS3 Terminal to SCF user to Service encapsulation; INAP CS3 SCF to Terminal Service to user encapsulation; session related Internet Protocols (including mobile IP); SS7 over IP; AAL2 or AALS Frame Relay; GSM GPRS; GSM HSCSD; dial-up modem capabilities. NOTE: VHE may potentially be supported by a variety of transport systems so if these capabilities are to be successful either interworking is required, or ubiquitous deployment becomes necessary. Otherwise one network cannot interwor
