1. A method for controlling configuration of dual-connectivity service for a user equipment device (UE), wherein the dual-connectivity service comprises the UE being served concurrently by a first access node over a first connection according to a first radio access technology (RAT) and by a second access node over a second connection according to a second RAT, wherein the first access node operates on a frequency band and provides the first connection on the frequency band, the method comprising:
determining by the first access node, while the first access node is serving the UE over the first connection on the frequency band, that the UE supports both (i) single-band dual-connectivity in which the second connection with the second access node would be on the same frequency band as the first connection with the first access node and (ii) dual-band dual-connectivity in which the second connection with the second access node would be on a different frequency band than the first connection with the first access node; and
based at least on the determining, deciding by the first access node to configure the single-band dual-connectivity for the UE and accordingly configuring the single-band dual-connectivity for the UE.
