Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“

16、, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Executive summary The present document propose

17、s and analyses an hybrid access network combining one or several terrestrial access technologies (Fixed or Mobile Service) together with a satellite broadband access network (Fixed Satellite Service) in order to enhance end users Quality of Experience of broadband service delivery primarily in under

18、-served areas where Internet service is available over terrestrial access technologies but delivering rates below that expected of Next Generation Access. This hybrid access network will support all the telecommunications services typically offered on Next generation access technologies, including h

19、igh bandwidth applications such as video conferencing, live streaming and video on demand via the satellite link along with the latency sensitive applications such as highly interactive online game play via the relatively slow terrestrial link. Intelligent Gateways route the traffic between terrestr

20、ial and satellite access technologies according to the Quality of Service requirements associated to the various service components with the objective to maximize the overall Quality of Experience for the users (large bandwidth and low latency). In addition, the hybrid network ensures a higher resil

21、iency towards potential interruption of service on the terrestrial access link. The present document aims at: Providing an overall description of the hybrid access network architecture with special emphasis on integration aspects with a public packet switched core network on one hand and the home ne

22、twork environment on the other hand; Proposing suitable metrics to compare the Quality of Experience (QoE) over such hybrid access network with respect to single access network technology; Identifying existing standards that have to be modified and additional standards that have to be created for en

23、abling this kind of scheme.

49、oadBand service especially in underserved areas at a comparable quality of experience to Next Generation Access networks capabilities. The underlying concept can be illustrated with the following use cases: Business: Mrs McMiggins needs to work from home - a challenge with a highly IT intensive job. She frequently needs to upload and download large data files, typically several Gbytes. The download time experienced using a small capacity rural ADSL service causes problems, with on-line collaborators having to wait whilst files are
