  • Patent number: 8509800
    Abstract: Systems and methods are provided for adaptive control of call quality-of-service. Using the systems and methods, if the uplink of a given mobile station is congested, the quality of the data, e.g., video data, sent by the mobile station along its uplink is adjusted to allow an optimal number of calls to be transmitted through the congested location. A centralized base station controller (CBSC) may obtain congestion information, such as frame loss ratio or frame delay, from its portion of the mobile network. The CBSC then relays this information to a mobile station and/or to a CBSC associated with one or more mobile station(s) at the other end of the call. The mobile stations may then adapt the quality of the video conferencing accordingly. Using the disclosed systems and methods, bandwidth utilization may be improved, allowing a high number of calls to be completed, and reducing the occurrence of dropped calls.
