Abstract: Systems, methods, and computer-readable media are provided for optimizing user plane node selection process during a process of handing over user equipment between two communication networks. In one aspect, a method includes receiving, at a network component, a session creation request for handing over the user equipment, the user equipment having a current active communication session within a first communication network with a first node of the first communication network, the session creation request including an identifier of the first node; receiving, at the network component, a list of candidates to serve as a user plane serving gateway for the user equipment in the second communication network; and selecting, by the network component and based on at least the identifier of the first node, the first node from the list of candidates to serve as the user plane serving gateway for the user equipment in the second communication network.

Abstract: A method, computer system, and computer program product are provided for providing 5G-as-a-Service. A network repository function is queried by a network management function to obtain identifying data for each of a plurality of radio base stations. A ping test is initiated by the network management function and based on the identifying data to be performed between at least one access and mobility management function (AMF) and each of the plurality of radio base stations to determine latencies between the at least one AMF and each of the plurality of radio base stations. A connection is initiated between the at least one AMF and a first radio base station of the plurality of radio base stations based on identifying a lowest latency between the at least one AMF and the first radio base stations.

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: A network element configured to support charging for a service in a network accesses policy rules defining a rating group to be used for offline charging. While a protocol data unit (PDU) session for user equipment is being established in the network, the network element sends, to a charging function configured to send charging data records related to service usage to a billing domain, a charging data request that establishes offline charging for the PDU session and indicates the rating group. The network element also receives, from the charging function, a charging data response including one or more triggers and thresholds for the rating group for the offline charging.
