METHOD OF IMPROVING CHANNEL UTILIZATION

摘要

The present invention provides improvements on latency on highest priority messaging and channel utilization in a time-slotted access channel structure. New superframe structures are presented where scheduled, but unused access slots can be utilized by secondary nodes.

1. A method of improving channel utilization in a time slotted channel access structure in a network, the method comprising;
defining a user priority for an outstanding packet in a node; based on the user priority defining a priority for the node; means for sensing a transmission; the time slotted channel access structure comprising, at least one access phase; dividing the access phase into number of access slots; sensing in the beginning of the access phase if a transmission from the highest priority node exist; if no transmission is sensed a node with a lower user priority may initiate transmission.
