doc.: IEEE /xxxr0 Submission May 2004 Stephen McCann, Siemens Roke ManorSlide 2 Objective Presentation to IEEE to describe the scope and work of the new IEEE WIEN Study Group.

doc.: IEEE /xxxr0 Submission May 2004 Stephen McCann, Siemens Roke ManorSlide 3 IEEE Interworking Interworking is defined as the functions and protocols necessary for integration of a wireless ethernet hotspot (STA and AP) within an existing network (such as a public cellular one), maintaining security, QoS and control.

doc.: IEEE /xxxr0 Submission May 2004 Stephen McCann, Siemens Roke ManorSlide 4 Motivation Hotspot use is currently gaining interest not only with ISPs but also with Cellular operators. It will become an increasing larger issue in public communications and it is felt by many that interworking of hotspots to external networks must be addressed by the IEEE , even if the conclusion of an initial investigation is that further standardization is not actually required.

Additionally it will enable IEEE devices to become high end terminal devices allowing user access to services only available within the cellular communications market. It is felt that both terminal and access point manufacturers will benefit from this expansion.

doc.: IEEE /xxxr0 Submission May 2004 Stephen McCann, Siemens Roke ManorSlide 7 Scope Identify technical requirements, such as those on the MAC layer. Determine impacts on IEEE , for example: –network selection: is anything additional required in the MAC to support network selection, such as operator advertisement, discovery of network capabilities before authentication etc. –resource management: MAC layer interactions with end-to- end resource allocation protocols, and exchange of information between MAC and higher layers to support admission control, accounting, resource monitoring. Decide whether a TG is needed, and if so define PAR and 5Criteria.

doc.: IEEE /xxxr0 Submission May 2004 Stephen McCann, Siemens Roke ManorSlide 8 Work A decision regarding the creation of a Task Group Creation of PAR and 5Criteria with the objective of producing an output document which defines how to interwork IEEE equipment with external networks (Cellular, Enterprise, ISPs) and where the control of such a system lies. Draft set of input requirements (e.g. layer 2 and layer 3 interactions) Determine relationships with other IEEE 802 groups. To underpin specific requirements raised by external standardization bodies

doc.: IEEE /xxxr0 Submission May 2004 Stephen McCann, Siemens Roke ManorSlide 10 Issues IEEE has to support wireless cellular functionality regardless of IEEE output –WIEN TG (possibly) will have mandate to write amendment to IEEE standard WIEN would like IEEE to complete their media independent handoff work so that it can ensure conformance to that model. WIEN requires IEEE issues, regarding handoff models, which have specific impacts on IEEE
