DYNAMIC UPGRADE OF QUALITY OF SERVICE IN A PACKET SWITCHED NETWORK

摘要

A system (2) and method for allocating system resources to provide a selected quality of service in a connection with data communications. A mobile user station (10) requests a first quality of service level for a data communication session (52). In response to a determination that system resources for providing the first quality of service level are unavailable (54), the system assigns resources for providing a second quality of service level for the data communication session (58). Thereafter, during the communication session, the system monitors the availability of system resources (62). If system resources for providing the first quality of service level become available, the system allocates the system resources for use by the user station and upgrades or downgrades the communication session accordingly (64).
