Abstract: A method and system to help address excessive RAB-modification requests as may happen when a UE is connected with and served by a first access node and the first access node repeatedly configures and de-configures dual connectivity for the UE where the UE would be connected with and served concurrently by the first access node and a second access node, with each configuring and de-configuring including a RAB-modification request to transfer a RAB of the UE between being anchored at the first access node and being anchored at a second access node. A computing system could detect that the rate of such RAB-modification requests is at least predefined threshold high and could cause the requests to be discontinued, such as by causing the first access node to at least temporary stop sending such requests.

Abstract: A wireless communication system serves UEs over a 5GNR access point and a non-5GNR access point. The wireless base station transfers an attachment message for a UE to a network controller. The network controller transfers network signaling for the UE to the data network element responsive to the attachment message. The data network element transfers user data for the UE. The wireless base station transfers another attachment message that indicates a 5GNR attachment for another UE to the network controller. The network controller transfers other network signaling indicating the 5GNR attachment for the other UE to the data network element responsive to the other attachment message indicating the 5GNR attachment. The data network element transfers other user data for the other UE and monitors quality-of-service for the transfer of the other user data responsive to the 5GNR attachment indication in the other network signaling.
