Techniques are provided herein for helping to address excessive Gx signaling. A Presence Reporting Area (PRA) feature coupled with Dual Connectivity New Radio (DCNR) / 5G Non-Standalone (NSA) network deployments enable Packet Data Gateways (PGWs) to offer Quality of Service (QoS) upgrade/downgrade of the respective bearer that was switched as part of a path update procedure based on the PRA Identifier (PRA-ID). This avoids upgrading/downgrading all the bearers associated with the Packet Data Network (PDN). Without these techniques, when the Master eNodeB (MeNB) triggers a path update for certain bearers, the Policy and Charging Rules Function (PCRF) would end up upgrading/downgrading the QoS of all the Policy and Charging Control (PCC) rules associated with the Internet Protocol Connectivity Access Network (IP-CAN) session, essentially all the bearers associated with the User Equipment (UE).
