Abstract
The present invention provides a method and an apparatus for controlling service quality of data communications in a wireless network in which quality of service control for voice over internet protocol packets is provided on a downlink shared channel. A method is provided for a wireless communications between at least a first and a second service user. The method comprises prioritizing transmission of voice over internet protocol packets for the first and second service users over a shared downlink channel based on a first end-to-end delay that the first service user experiences relative to a second end-to-end delay that the second service user experiences. For example, such a priority adaptation may provide quality of service control for voice over internet protocol over a high-speed downlink packet access channel based on an end-to-end delay that a mobile-to-mobile user may be currently experiencing relative to a mobile-to-land user. In this way, a scheduler at a base station of a communications system may maximize use of voice over internet protocol capacity while maintaining an acceptable level of end-to-end delay for different users of mobile stations.
