摘要
Delivering of IP services is becoming increasingly important for wireless access networks, HeliNet being their representative based on high altitude platforms. In accordance with that new problems arise regarding Quality of Service (QoS) or Class of Service (CoS) provision and resource allocation. Traffic QoS/CoS should be managed on multiple communication layers such as application, network and radio interface layer. In the network layer IP QoS models can offer various levels of QoS to the application layer, while radio interface should provide mechanisms, which can guarantee required QoS level to IP. Mapping of QoS/CoS parameters between the network layer and radio interface can be performed in a suitable convergence sublayer. This paper addresses the IP transmission over the HeliNet radio interface. Using a simulation model it is shown that introduction of scheduling algorithms, as part of the uplink Medium Access Control (MAC) protocol, improves the ability of radio interface to offer the required QoS/CoS to IP.
