摘要：The increasing demand for converged media services across Europe promotes the deployment of a range of broadband network technologies. Existing and emerging services that become available to the end user are currently supported by wireline access technologies such as relatively limited capacity cable modems, and ADSL or high capacity FTTx/VDSL as well as wireless technologies such as HSDPA, WiFi and WiMax. However, in order to achieve the required data rate, cell distances have to be small. This will result in a large number of cells to be interconnected to the mobile backhaul network. Serving a large number of cells with point to point links is extremely inefficient. This makes backhaul architectures based on Passive Optical Networks (PONs) very attractive. In this convergent networking scenario seamless mobility across this heterogeneous network infrastructure and service portability across segments of different technologies still face severe limitations. While international standards evolve to enable interoperability there is still a need for an integrated resource management framework and flexible service delivery mechanisms. A main objective is to achieve superior performance in terms of capacity, dynamic resource allocation, Quality of Service (QoS) and flexible service provisioning models supporting fast network reconfiguration, efficient network management and reduced cost (CapEx/OpEx). In this work we present an architecture and a resource allocation framework that allow autonomic operation and Service Level Agreement (SLA) negotiation between the mobile network operator (MNO) and the backhaul provider.
