Abstract: Embodiments herein use a real-time system to conduct a line of sight (LOS) survey between radio sites. The system includes a drone controlled by a UAV LOS System (ULS) server to gather information regarding the LOS path between the radio sites. In one embodiment, the ULS server instructs the UAV to travel a LOS path between a first location and a second location, and determine a Fresnel radius at one or more defined locations along the LOS path between the first location and the second location. The ULS server determines a Fresnel zone between the first location and second location based in part on the determined Fresnel radius for each of the defined locations along the LOS path. The ULS server evaluates the Fresnel zone to determine if the LOS path can support a LOS wireless communication link.

Abstract: A first virtual machine executing on a centralized management node provides a first image file to a first computing entity arranged within a first point of delivery. The first image file includes a first boot configuration file or a first ramdisk file. A second virtual machine provides a second image file to a second computing entity arranged within a second point of delivery different from the first point of delivery. The second image file includes a second boot configuration file or a second ramdisk file. The first virtual machine provides a third image file to the first computing entity. The third image file comprises a first operating system installation file. The second virtual machine provides a fourth image file to the second computing entity. The fourth image file comprises a second operating system installation file.

Abstract: Techniques are provided to inform a mobile packet core of the access network/radio access technology (AN/RAT) change with the use of in-band signaling along the user plane and hence reduce signaling between radio access network and mobile packet core network. A new extension header content is defined to signal the AN/RAT change information, Cell Group changes and acknowledging the same. Further still, a method is provided to handle AN change notification for split bearer scenarios by introducing a split bearer flag for the mobile packet core to be notified of the predominant access type serving the subscriber data session in 5G Non-Stand Alone (NSA) Option-3, Option-3A and Option-3X, so that static or dynamic configurations can be applied by the mobile core network accordingly.

Abstract: A network function (NF) entity in a communication network receives User Plane Function (UPF) registration information for a plurality of UPFs, the registration information including a respective network attribute for each UPF. The NF entity associates each UPF with a corresponding network based on the respective network attribute, and map one or more User Equipment (UE) to the corresponding network based on a security policy to create a UE-to-network table. The NF further receives a request to establish a session for a subsequent UE, the request including a subsequent UE identifier, and determine an access permission for the subsequent UE to access the corresponding network based on the subsequent UE identifier and the UE-to-network table. The NF selects one UPF from the plurality of UPF to service the session for the subsequent UE based on the access permission, and an association between the one UPF and the corresponding network.

Abstract: When a packet data session is established for a user equipment (UE), a comparative assessment of load information factors from different sets of load information factors associated with a plurality of user plane function (UPF) instances may be performed. Each set of load information factors of a UPF instance may include predicted load information factors indicative of a predicted load at the UPF instance. A UPF instance may be selected for the packet data session of the UE based on the comparative assessment. The comparative assessment may additionally consider a predicted load contribution of the packet data session to be established for the UE. A data analytics function may utilize a model (e.g. a multiple linear regression model) to calculate predicted load contribution factors, where the model is derived based on historical usage data from previous sessions of one or more UEs, for example, data from charging data records (CDRs).

Abstract: In one example, a Virtual Network Function Manager (VNFM) obtains, from a monitoring agent that is configured to monitor a Virtual Network Function (VNF) for a presence of a technical issue with the VNF, an indication of the presence of the technical issue with the VNF. The monitoring agent is deployed at a remote site. Based on the indication of the presence of the technical issue with the VNF, the VNFM determines a resolution for the presence of the technical issue with the VNF. The VNFM automatically implements the resolution for the presence of the technical issue with the VNF.

Abstract: Techniques are presented in which a new information element signaling priority of a management entity is included in a setup (e.g., S1-Setup) response or configuration update message sent by a management entity to a base station entity. The base station entity interprets this priority information along with the relative capacity information in an appropriate way to load-distribute the traffic/calls to highly preferable management entity instances (at a local site) when they are available, and switchover/failover to lower preference management entity instances (at a remote site) when there is a local site outage/failure or insufficient capacity in a geo-resilient pooled network.

Abstract: Presented herein are efficient techniques through which a Third Generation Partnership Project (3GPP) Access and Mobility Management Function (AMF) may retrieve information for a Mobility Management Entity (MME) to support graceful mobility for various inter-Radio Access Technology (inter-RAT) mobility scenarios. In one example, a method includes determining, by an AMF, an inter-RAT mobility event for a user equipment; identifying, by the AMF, an MME associated with the inter-RAT mobility event based, at least in part, on MME information contained in a network database; and transferring context information for the user equipment between the AMF and the MME. In one instance, the network database may be a Network Repository Function (NRF) for a 3GPP Fifth Generation mobile network and the MME information may be associated with an MME network function type stored in the NRF.
