1. A method for controlling dual connectivity establishment in a wireless communication system including a first access node and a second access node, wherein the first and second access nodes cooperatively support providing user equipment devices (UEs) with dual connectivity service, wherein data flows between the first and second access nodes, and wherein a proper subset of the data that flows between the first and second access nodes is user-plane data of the dual connectivity service, the method comprising:
detecting that a total volume of the user-plane data that flows between the first and second access nodes is at least as high as a predefined threshold; and
based at least on the detecting, blocking new establishment of the dual connectivity service, wherein blocking new establishment of the dual connectivity service comprises blocking at least one UE from becoming concurrently connected with both the first access node and the second access node.
