Abstract
In LMDS systems the downlink bandwidth is continuously varying in time because each downlink burst uses a network termination individual modulation and coding (Physical layer) scheme, the higher layer (IP) functions cannot perform service priority respecting traffic shaping. The invention proposes mainly to combine both framing and IP layer functions within one inter-layer framer. The combination of both information ensures QoS provisioning in case of multi-modulation and multi-coding environment. The QoS queue server gets always informed on the actual amount of available data frame bits from the downlink framer and therefore, the QoS queue server is able to decide on the next IP packet or packet fraction to transport. This decision is always based on service priority aspects. As soon as the downlink frame is filled—supposing that the maximum downlink frame rate is always lower than the internal processing in the inter-layer framer—the QoS server stops the data delivery.
