Call for Papers ------------------ VTC 2003 - Symposium on Wireless LAN / Cellular Internetworking

Motivation and Scope --------------------- The recent evolution and successful deployment of WLAN systems worldwide has fuelled the need for interworking mechanisms between WLANs and cellular telecommunication networks, such as GSM/GPRS, UMTS, cdma2000, etc. Several forums and standardization bodies worldwide have already initiated activities for exploiting WLAN technology and integrating this technology into cellular telecommunication networks. In addition, several R&D projects are currently underway, which address vertical handovers between WLANs and UMTS, as well as common authentication, authorization and accounting procedures.

It is evident that the integration of WLANs and cellular telecommunication networks is of paramount importance nowadays, from both business and technology points of view. However, this integration poses several challenges, such as vertical handovers, consistent QoS provision, common authentication and billing, etc, which call for extensive studies and efficient solutions.

The VTC 2003 symposium on Wireless LAN / Cellular Interworking aims to address the aforementioned challenges and to propose and analyze efficient interworking solutions. It also aims at reporting the recent results of related R&D and standardization activities worldwide. In particular, the most significant areas that will be addressed are the following: ¨ Interworking requirements, issues and architectures ¨ Seamless roaming between WLAN and cellular networks ¨ Common authentication and security: issues and solutions ¨ Common billing: issues and solutions ¨ Voice over WLAN ¨ Interworking scenarios and case studies ¨ Inter-system handover ¨ QoS interworking ¨ Value added services with WLAN-Cellular network integration ¨ Performance evaluation studies ¨ Standardization activities ¨ Extension of location services to WLANs.

Technical Paper Submission Guidelines -------------------------------------- Authors are invited to submit an extended abstract (up to 2 pages) and a short abstract (approx. 150 words) of their original papers for review. The submission must be made on line through the EDAS Conference Management System, http://edas.info. After login, select "VTC 2003 - Wireless LAN/cellular internetworking" and follow the instructions for submission. Soft copies in MS Word or PDF formats are accepted.
