Transport network congestion control for enhanced uplink communications

摘要

For a mobile radio connection having at least two uplink flows, a determination is made whether one of the uplink flows from a non-serving cell has a better radio link quality than another of the uplink flows from a serving cell. A congestion condition in the radio access transport network is monitored for those uplink flows. If congestion in the radio access transport network for the non-serving cell uplink flow is detected when that uplink flow is associated with the better radio link quality, then a message is generated for transmission to the mobile radio terminal to reduce a rate at which the mobile radio terminal transmits data for the connection to the radio access transport network rather than the non-serving cell discarding uplink data packets.
