1. A method to control configuration of dual-connectivity service for a user equipment device (UE), wherein the dual-connectivity service includes the UE being served concurrently by a master access node (MN) over a first air-interface connection and by a secondary access node (SN) over a second air-interface connection, the method comprising:
identifying a plurality of pairs of access nodes as candidate pairs of access nodes to be the MN and SN for the dual-connectivity service;
for each identified pair of access nodes, determining an inter-access-node communication delay;
comparing the determined inter-access-node communication delays of the identified pairs of access nodes and, based on the comparing, selecting one of the identified pairs of access nodes to be the MN and SN for the dual-connectivity service; and
causing the dual-connectivity service to be set up for the UE with the selected pair of access nodes being the MN and SN for the dual-connectivity service.
