Use of threshold RAB-modification rate as basis to control configuration of dual connectivity

A computing system comprising:

• at least one processing unit;
• at least one non-transitory data storage;
• and
• program instructions stored in the at least one non-transitory data storage and executable by the at least one processing unit to carry out operations when a user equipment device (UE) is connected with and served by a first access node, the operations including, while the UE remains connected with and served by the first access node:
• monitoring a rate of radio-access-bearer (RAB) transfer requests each requesting transfer of a RAB of the UE between being anchored at the first access node and being anchored at a second access node,
• detecting that the monitored rate of RAB-transfer requests is at least predefined threshold high, and
• responsive to the detecting, discontinuing transmission of further such RAB-transfer requests for the RAB of the UE,
• wherein each RAB-transfer request that requests transfer of the RAB of the UE from being anchored at the first access node to being anchored at the second access node is part of configuring dual-connectivity service for the UE to be served concurrently by the first access node and the second access node, and
• wherein each RAB-transfer request that requests transfer of the RAB of the UE from being anchored at the second access node to being anchored at the first access node is part of de-configuring the dual-connectivity service.
