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.

Abstract: A method, performed by a wireless resource controller, includes receiving an indication that a first wireless device is experiencing data loss over a communication channel provided by a wireless access point utilizing a first radio access technology (RAT). The method includes determining a plurality of congestion window values associated with other wireless devices that share a shared wireless resource with the first wireless device. The shared wireless resource is provided by a base station of a cellular network utilizing a second RAT. The method includes determining an initial congestion window value for the first wireless device based on the plurality of congestion window values associated with the other wireless devices. The method includes transmitting data to the first wireless device from the base station in accordance with the initial congestion window value for the first device in order to satisfy a performance criterion for the first wireless device.

Abstract: Techniques are described herein for optimizing Quality of Service (QoS) enforcement for handover between different Radio Access Types (RATs). In one example, during an initial user session establishment procedure involving a first RAT, one or more QoS parameters corresponding to a second RAT are obtained. The one or more QoS parameters corresponding to the second RAT are stored to generate one or more stored QoS parameters corresponding to the second RAT. During a handover procedure from the first RAT to the second RAT, the one or more stored QoS parameters corresponding to the second RAT are allocated.

Abstract: In one example, a base station entity, for a mobile wireless network, obtains an indication of a first potential Guaranteed Bit Rate (GBR), a first unique identifier associated with the first potential GBR, a first priority level associated with the first potential GBR, a second potential GBR, a second unique identifier associated with the second potential GBR, and a second priority level associated with the second potential GBR. Based on the first priority level being associated with a higher priority than the second priority level, the base station entity determines whether the first potential GBR can be supported. If so, the base station entity provides an indication of the first unique identifier to a core network associated with the mobile wireless network, wherein the indication of the first unique identifier prompts the core network to enforce the first potential GBR.

Abstract: At least one offline usage reporting rule is instantiated at a user plane element of the telecommunications network, wherein the usage reporting rule indicates at least one trigger condition. The user plane element detects an occurrence of the at least one trigger condition in traffic processed by the user plane element and, in response, generates and temporarily stores a first usage report. Subsequently, the user plane element detects an occurrence of an immediate reporting condition and, in response to detecting of the occurrence of the immediate reporting condition, sends the first usage report to a control plane element.

Abstract: Techniques are presented that ensure Quality of Service (QoS) for Wi-Fi® calling and other Internet Media Services (IMS) when a user connects from a carrier-operated public Wi-Fi network to an IMS. A first packet including a domain name system (DNS) request received from a wireless mobile device via an access point is intercepted at a networking device. A network address of a collocated gateway device associated with the networking device is sent to the wireless mobile device in response to the DNS request. A second packet is received from the wireless mobile device including the network address of the collocated gateway to establish a network communication via the collocated gateway device. First QoS parameters associated with the network communication are received from the collocated gateway device and a notification message is sent to the access point, the notification message including the first QoS parameters.
