Priority and flow control in a multi-user spread spectrum channel

摘要

The present invention provides a method of controlling packet data from multiple types of data sources, including data sources having reroutable data and data sources having non-reroutable data, the multiple types of data sources flowing into a multiuser channel (56) in a wireless spread spectrum code division multiple access communication system, the method comprising: providing a queue (54, 76-86) for incoming data of each data source; tracking a backlog of data in the queue (54, 76-86); and limiting data flow from each of the data sources based on in part the tracked backlog; the method characterized by: selectively rerouting packet data intended to be transmitted over the multiuser channel (56) to another channel based on in part the tracked backlog.
