Minimum bit rates for user equipment can be adjusted in a manner that accounts for the impact of the minimum bit rates on network performance. Ranges of minimum bit rates can be established for user equipment, and minimum bit rates can be adjusted within the ranges. A minimum bit rate can be decreased when it produces a relatively higher impact on network performance, and the minimum bit rate can be increased when it produces a relatively lower impact on network performance. ## Claims ### Claim 1 A method, comprising: deploying, by network equipment comprising a processor, a minimum bit rate policy for application of the minimum bit rate policy by a radio access network node, wherein the minimum bit rate policy comprises: a group of network conditions;
