Patent ID: 11146412

Abstract:
Disclosed are technologies for optimally utilizing 5G-NSA network resources via an Aggregate Maximum Bitrate (AMBR) feedback mechanism. A User Equipment (UE) is registered with a 5G-NSA network environment and a 5G AMBR is negotiated. A bearer-specific timer is triggered in response to detecting one or more data flows to the UE. Next, a Secondary Radio Access Technology (RAT) Data Usage Report is monitored for. In response to the bearer-specific timer expiring without a Secondary RAT Data Usage Report being received, it is determined that the UE is not currently being served by a 5G RAT. Subsequently, local rate limiting is performed to reduce the negotiated 5G AMBR to a limited AMBR having a lower bitrate than the negotiated 5G AMBR. The UE connection to the 5G-NSA network environment is then configured with the limited AMBR.
