Abstract: A method selects a path for forwarding a data packet in a wireless communication system. A system capacity versus delay impact curve is calculated for a direct path to mobile station. The direct path has a capacity cost based on communication quality of a direct link between a base station and the mobile station. This curve is shifted by a predetermined time corresponding to an additional delay over a relay path to produce a projected capacity curve for the relay path having a second capacity cost determined according to a combined measure of signal quality of multiple links in the relay path. The second capacity cost is multiplied by a capacity cost ratio to produce a relay capacity curve. The direct path or the relay path is selected based on a comparison of the system capacity versus delay impact curve and the relay capacity curve according to a QoS requirement.

Abstract: Wireless network nodes are configured to transmit a request to update the quality of service associated with an existing radio access bearer. In response to the request, the radio access bearer is updated without tearing down the established radio access bearer. Some applications can be associated with one or more quality of service indicia, so that as service demands change in use of a single application, requests for quality of service updates can be transmitted by, for example, a mobile station or other network nodes. Updates can be initiated by other user equipment or by network nodes such as gateway GPRS support nodes. Service interruptions can be reduced by preserving a radio access bearer (RAB), which is particularly useful for a stationary mobile station that continues to communicate with the same serving GPRS support node.

An admission control facility (ACF) responds to the initiation request by performing admission analysis to determine whether to initiate the data transfer. The ACF sends one or more packets to the second network client. In response, the second network client sends acknowledgment packets back to the ACF.
