    Abstract: Various arrangements for performing intelligent cellular channel management are presented herein. A physical cellular communication channel may be established between a user equipment (UE) and a cellular network for sending a short message service (SMS) message in response to a cellular service request from the UE. One or more characteristics of the UE, the SMS message, or both may be analyzed. A duration of time for which the physical cellular communication channel is to be kept active may be based on the analyzed one or more characteristics. A channel maintenance instruction may be transmitted to keep the physical cellular communication channel active based on a cellular network messaging controller determining to adjust the duration of time for which the physical cellular communication channel is kept active.

    Abstract: Disclosed is a method performed by a UE device that routes traffic to a 5G Core Network. The method includes receiving a first ATSSS rule including first traffic descriptor information corresponding to a first type of traffic for a first type of service and first steering mode information including a first network indicator corresponding to a first MNO, and a second ATSSS rule including second traffic descriptor information corresponding to a second type of traffic for a second type of service and second steering mode information including a second network indicator corresponding to a first MVNO or a second MNO; transmitting the first type of traffic for the first type of service a first 3GPP access network operated by the first MNO; and transmitting the second type of traffic for the second type of service to the first 3GPP access network operated by the first MNO.

    Abstract: An approach for estimating Round Trip Time (RTT) such as used for estimating a location of mobile User Equipment (UE) devices, particularly adapted for Open Radio Access Networks (O-RANs) that disaggregate basestation functions into a Radio Unit (RU) and a Distributed Unit (DU) or Central Unit (CU). A Positioning Reference Signal (PRS) is transmitted by the RU according to schedule determined by the DU or CU. A Sounding Reference Signal (SRS) is returned by the UE to the DU or CU, with an estimate by the UE of its internal delay. The RU reports an estimate of the difference seen between a time of transmission of the PRS and time of reception of the SRS. The RTT is then estimated by subtracting the UE's internal delay from this difference. RTTs taken between the UE and two or more RU's may further determine a location of the UE.

    Abstract: Embodiments are directed towards systems and methods for user plane function (UPF) and network slice load balancing within a 5G network. Example embodiments include systems and methods for load balancing based on current UPF load and thresholds that depend on UPF capacity; UPF load balancing using predicted throughput of new UE on the network based on network data analytics; UPF load balancing based on special considerations for low latency traffic; UPF load balancing supporting multiple slices, maintaining several load-thresholds for each UPF and each slice depending on the UPF and network slice capacity; and UPF load balancing using predicted central processing unit (CPU) utilization and/or predicted memory utilization of new UE on the network based on network data analytics.

    Abstract: An example system and method may manage interference for wireless devices in a non-terrestrial network environment. An example system may determine spectrum blanking ranges for a wireless client device, where the spectrum blanking range restricts wireless frequencies in the spectrum blanking range from being assigned to wireless client devices by ground node. The system may determine a signal quality indicator value for a wireless client device, determine an assignable spectrum range for the wireless client device based on the signal quality indicator value and the spectrum blanking range(s), and assign a channel to the wireless client device using the assignable spectrum range.

    Abstract: Systems and methods are provided to migrate a set of network functions between control planes of a network slice A and a network slice B; and a migration management unit to manage a gradual staged transfer of a subset of the plurality of network functions originally contained in the control plane of the network slice A to the control plane of network slice B wherein the gradual transfer is a migration of the plurality of network functions in a set of multiple stages to create the subset of the plurality of network functions in the control plane of slice B, wherein each gradual staged transfer includes the migration of a reduced subset of the plurality of network functions contained in the control plane of the network slice A reconfigured to the control plane of the network slice B.
