Wireless IP Network as a Generic Platform for Location Aware Service Support


Mobile/IP integration has started (GPRS) but suffers from low air-interface bit rate. 3G provides higher bit rates but in its first implementation will not improve significantly the access and integration capability for IP traffic. A sufficient radio capacity for IP traffic will be possible via WLAN and future evolutions of UMTS. WINE GLASS aims at integrating UTRAN and WLAN to an IP Core Network, with necessary exploration of access and core network architectures to provide QoS and mobility support. The Project will support the relevant standardisation groups. Location-aware applications will be addressed for business and public usage, in order to verify the ability of the integrated network to offer transparent solutions for ubiquitous use of the IP-base Core Network. WINE GLASS will rely on Access Segments and IP-based Core Network. A real-time emulation will enable to evaluate alternative solutions for mobility, QoS control and service support.

This Project aims to contribute to the technical innovation and EU policies of the Community by exploiting the potential of IP-based wireless mobile multimedia networking with UMTS and WLANs. The objective of the Project is to exploit enhanced and/or new IP-based techniques to support mobility and soft-guaranteed QoS in a wireless Internet architecture incorporating UMTS and WLANs, and to explore their potential in enabling location- and QoS-aware application services for wireless mobile users. By its completion, the Project will have developed a wireless Internet testbed incorporating an IP backbone, UTRAN access to IP-based core network, and WLAN access to intranets, as a means to investigate, develop, test, integrate, validate and evaluate such innovative techniques and applications. Currently proposed techniques, such as Mobile-IP, IntServ, DiffServ, H.323 etc., are either non-scaleable or immature. As a result of this Project, more advanced techniques, together with ideas of their enabled location- and QoS-aware application services, should be submitted to 3GPP, SMG and IETF as contributions in UMTS and mobile multimedia Internet respectively.

Work description:
This Project will exploit the potential of IP-based wireless mobile multimedia networking in both public and This Project will exploit the potential of IP-based wireless mobile multimedia networking in both public and business contexts, by means of UMTS and WLAN respectively. The wireless Internet testbed will be constructed around an IP backbone, which could as well be the Internet. The UMTS environment will be composed of IP-based UMTS core network with emulated W-CDMA-based UTRAN access. The WLAN environment will be made up of intranets with commercial WLAN access.

With this testbed, support of mobility and soft-guaranteed QoS will be investigated at the IP level in both the contexts of the IP backbone and IP-based UMTS core network. The Project will also address such support in the UMTS W-CDMA FDD mode. Besides, also investigated will be the associated issues that may arise in the inter-working of mobility and QoS between UMTS, WLAN and the IP backbone.

Location- and QoS-aware application services will be conceived to exploit the support of mobility and soft-guaranteed QoS offered by the underlying wireless Internet architecture. Specifically, session/call control, possibly based on SIP/RTSP or H.323 will be enhanced to incorporate capability negotiation and location information functionality.

This Project will be realised in two phases.

Phase 1 technical activities will concentrate on technical requirements and expected results for the Project; hardware and software development and integration requirements for the wireless Internet testbed; assessment of intermediate research results with respect to mobility support in the wireless Internet architecture and location-aware application services.

Technical activities in Project phase 2 will include final integration of the wireless Internet testbed; assessment of final research results with respect to support of mobility and soft-guaranteed QoS in the wireless Internet architecture, as well as location- and QoS-aware application services.

During the Project, feedback from continuous technical assessments to technical development will take place as frequently and as timely as necessary to ensure high quality of the Project results. In dissemination of its results, this Project will contribute to 3GPP, SMG and IETF and participate in relevant IST concertation and clustering.

Key Issues

Integration of wireless access networks (UTRAN and WLAN) and the IP-based backbone in a convergent scenario involving a variety of service contexts.

Definition of service schemes suited for location-aware applications in an integrated wireless-IP context

The 1999 IST Workprogramme identifies clearly the basic innovation paths for mobile and wireless communication.

They can be summarised in the need of:
developing service control tools able to guarantee that personal and mobility services can be used in a seamless way, within a variety of environments and under the established location-dependent service profiles;
improving the technical basis for a convergent configuration of the wireless platforms, based on a complete integration of the advanced radio access systems with the IP-based networks;
identifying and evaluating new service support architectures, offering the necessary quality of service levels (e.g. delay, integrity) within the performance levels guaranteed by the underlying network platforms.

The WINE GLASS Project aims at contributing to the construction of the above perspective through the implementation of real configurations and services and the emulation of real-time environments. Two levels of investigation will particularly be addressed, namely the Wireless IP Network integration and the relevant service support functions.

Besides, contribution to standard bodies (3GPP, SMG and IETF) and pertinent publications constitutes the foreseen exploitation of Project results to the Telecommunication and IT communities.
