Abstract: Embodiments are directed towards systems and methods for managing user experiences during cellular telecommunication outages within a wireless telecommunication network, such as a wireless 5G network. Example embodiments include systems and methods managing user experiences during a cellular telecommunication network outage utilizing a backup data center. For example, in response to the distributed unit (DU) detecting there exists the failure in communication between the DU and the corresponding primary centralized unit control plane (CU-CP), the system causes the DU to switch from using the corresponding primary CU-CP to using the secondary CU-CP of a secondary CU hosted on the backup cloud-native virtualized compute instance based on utilizing a secondary ID pre-configured on the DU.

Abstract: Techniques described herein provide pooling of radio access network (RAN) resources in a disaggregated RAN in a manner that enables dynamic re-homing of RAN functions with minimal disruption to stateful communications. The RAN is a hierarchical arrangement of RAN units, each having an associated state at any given time. A RAN state pooling system (RSPS) is in communication with a pool of the RAN units via a high-speed communication channel. The RSPS is configured to maintain an updated repository of the state information for the RAN units in its serviced pool. In the event of re-homing from a first RAN unit to a second RAN unit in the pool (e.g., due to the first RAN unit failing, becoming overloaded, etc.), the RSPS provides the second RAN unit with the updated state information for the first RAN unit to facilitate a stateful re-homing.

Abstract: Embodiments are directed towards systems and methods for carrier aggregation and dual connectivity switching in a cellular network (e.g., a 5G network). Example embodiments include systems and methods for: the RAN functions supporting providing measuring and reporting particular items for dynamic carrier aggregation and dual connectivity switching; RAN dynamic carrier aggregation and dual connectivity switching with a network intelligence layer; RAN dynamic carrier aggregation and dual connectivity switching without a network intelligence layer; RAN dynamic carrier aggregation and dual connectivity switching based on availability of an inter-DU link and meeting latency/bandwidth criteria; RAN dynamic carrier aggregation and dual connectivity switching based on availability of an inter-DU link and meeting resource criteria; and prioritization for using CA instead of DC based on CQI information reported from UEs.

Abstract: Embodiments are directed towards an adaptive DU scheduler that increases the user experiences on higher channel bandwidths (BWs) while ensuring no drops for Voice over New Radio (VoNR) or other high priority traffic. Example embodiments include systems and methods for an adaptive distributed unit (DU) scheduler in a wireless telecommunication network, such as a wireless 5G network. Example embodiments include systems and methods that include: a central scheduler for maximizing overall throughput based on received parameter values; maximizing the overall cell site throughput; an intelligence layer that has an artificial intelligence and/or machine learning (AI/ML) model that increases the performance for all the cells by sending info to central scheduler for each of the cells; an intelligence layer that has an AI/ML models for each site type based on the traffic distribution across each cell; centralized RAN pooling; a containerized DU server with master a controller pod controlling individual cell pods; and a containerized DU server with a DU common scheduler managing all the cells.

Abstract: Various arrangements for performing dynamic resource blanking on a cellular network are presented herein. Based on orbital data for a satellite, a cellular network can determine user equipment (UE) conducting an active call using a particular frequency band at a base station. For each of the UE a handover can be performed of on-going calls to a different frequency band. Following completion of the handovers, use of the frequency band at the base station can be temporarily disabled.

Abstract: In response to detection that a capacity of the fronthaul link has been or will be exceeded, a software intelligence layer operating on a transport layer router that aggregates network traffic from the one or more radio units (RUs) causes a change in how in-phase and quadrature (IQ) data packets sent on the fronthaul link are handled to reduce use of the capacity of the fronthaul link. In another example embodiment, a software intelligence layer operating at an application layer of the wireless telecommunication network may perform one or more actions utilizing access to scheduler level information for the distributed units (DUs) to avoid the fronthaul link exceeding the capacity limit based on incoming IQ samples to a router that aggregates network traffic from one or more corresponding RUs.

Abstract: Embodiments are directed towards systems and methods for managing user experiences during cellular telecommunication outages within a wireless telecommunication network, such as a wireless 5G network. Example embodiments include systems and methods for utilizing an intelligence layer module external to the DU and in communication with the DU, a primary physical data center and a backup physical data center for managing user experiences during a cellular telecommunication network outage. The intelligence layer module external to the distributed unit (DU) communicates with the DU to activate and manage the radio resource manager (RRM) in the DU to reduce interruptions in service during the cellular telecommunication network outages.

Abstract: Systems, methods, and devices dynamically allocate bandwidth parts in response to conditions at cell sites. An example process assigns a first plurality of slices and a second plurality of slices to communicate on a bandwidth of a cell site. The cell site operates at a first level of power consumption. A changed operating state is detected at the cell site, and the first plurality of slices is assigned to communicate on a bandwidth part of the cell site in response to detecting the changed operating state. The bandwidth part is a subset of the bandwidth. The cell site operates at a second level of power consumption in response to assigning the plurality of slices to communicate on the bandwidth part. The second level of power consumption is less than the first level of power consumption.

Abstract: Systems and methods are provided for adaptive bandwidth (BW) management configuring an element management control unit including a set of distribution/central units (DU/CU) for monitoring power and traffic loads at a plurality of cell sites in a network; communicating with a BW management unit coupled to the element management system to adapt BW for users at cell sites by moving users to a set of smaller bandwidth parts (BWPs) at a cell site in response to a set of conditions of AC power outages and reduced traffic loads detected by the BW management unit, and in response to at least one of the detected conditions, instructing based on data from the DU/CU to the BW management unit to move user traffic to a designated lower BWP of the set of smaller BWPs at the cell site while shutting down other BWPs at the cell site to save the power of an operating cell site.
