Methods for congestion control in wireless networks

摘要

A centralized self optimizing network and policy server is configured to control congestion within at least one cell in a wireless network by coordinating application of radio frequency congestion control mechanisms affecting all users within the cell and application of core network congestion control mechanisms associated with individual users within the cell.

1. A method for congestion control in a wireless network, the method comprising:
controlling congestion within at least one cell in the wireless network by coordinating application of radio frequency congestion control mechanisms affecting all users within the cell and application of core network congestion control mechanisms associated with individual users within the cell, the controlling step including,
applying the radio frequency congestion control mechanisms affecting all users within the cell,delaying application of the core network congestion control mechanisms for users within the cell for a delay interval during which the applied radio frequency congestion control mechanisms take effect within the cell,determining, after expiration of the delay interval, whether to apply the core network congestion control mechanisms for the users within the cell, andselectively applying the core network congestion control mechanisms for the users within the cell based on the determining step.
