Abstract: In one aspect, the present invention advantageously provides far greater granularity in adjusting the maximum (schedulable) uplink bit rates of users than is directly available from a defined grant table that is used for making scheduled uplink grants to those users. As a non-limiting example, the EUL scheduler in a NodeB in a WCDMA network calculates the “effective” bit rate desired for one or more users over a given time interval, and determines the pattern of scheduling grants to make from the grant table over that interval, to produce the desired effective bit rate(s). This capability enables the EUL scheduler to make relatively fine fractional adjustments to the aggregate uplink data rate for a plurality of users, thus allowing much more precise reductions in the aggregate uplink data rate of those users. The EUL scheduler makes these more precise adjustments, for example, in response to indications of congestion on the backhaul connection between the NodeB and its supporting RNC.

Once the link groups are established, traffic over the groups of links (e.g., routes to reachable address prefixes) may be managed and optimized according to the group policies, such as in accordance with Optimized Edge Routing (OER) techniques.
