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: Methods and systems for adaptive bandwidth application are provided. An example method includes generating multiple RAN slices of a network for multiple network consumers, selecting one or more of RAN slices and assigning the one or more RAN slices to each one of multiple network consumers, dividing a radio frequency spectrum into multiple radio frequency bands, assigning one or more of the multiple bands to each one of the multiple RAN slices, associating one or more QoS priority indicators to each one of the bands assigned to the RAN slices, allocating one or more allotments of the one or more bands to each RAN slice, monitoring continuously real-time bandwidth usage by each one of the multiple RAN slices, and adjusting automatically and adaptively a total bandwidth allocated to each RAN slice, according to the one or more QoS priority indicator associated with the RAN slice and a predetermined rule.

Abstract: Systems and methods for slice-specific adaptive resource allocation are provided. An example method includes generating multiple RAN sub-slices within a RAN slice of a network, assigning a first band to the RAN slice. The first band has a first BWS and a second BWS, the first BWS is allocatable to each one of the RAN sub-slices, and the second BWS is allocatable to qualified RAN sub-slices. The method further includes assigning a first allotment of the first BWS to an identified RAN sub-slice, monitor continuously real-time bandwidth usage of the first BWS by the identified RAN sub-slice, and determine whether the first allotment allocated to the first RAN sub-slice is sufficient to achieve predetermined QoS attributes of the first RAN sub-slice.

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 reducing power consumption at a cell site. An example process includes the steps of detecting a change from a normal operation at a cell site, initializing a small bandwidth part (BWP), and moving user equipment communicating with the cell site from a dedicated BWP to the small BWP in response to the change from the normal operation at the cell site. A return to normal operation is detected at the cell site. The process includes restoring the user equipment to the dedicated BWP in response to the return to the normal operation at the cell site.

Abstract: Various examples of automated processes, computing systems, devices and other aspects of a wireless data network are disclosed herein. According to various embodiments, message flooding in the wireless network is reduced through the use of “dummy” messages from the radio unit (RU) to the distributed unit (DU) or layer two (L2) switch. The dummy messages tend to prevent timeout of the RU's data in the L2 switch's routing tables, thereby prolonging the period of time that the L2 switch is able to more efficiently direct subsequent traffic toward that particular device.

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: Methods and apparatuses for improving telecommunications services by intelligently deploying redundant links within a data center hierarchy to satisfy latency, power, availability, and quality of service requirements are described. A data center hierarchy of a cellular network is established with a first data center layer, a second data center layer, and a third data center layer. A first redundant link is established between a first node in the first data center layer and a third node in the third data center layer. In response to detecting that a failure rate of the first data center layer exceeds a threshold failure rate, the first redundant link is removed and a second redundant link is added between the third node and a second node in the second data center layer.

Abstract: Methods and apparatuses for improving telecommunications services by intelligently deploying radio access network components and redundant links within a data center hierarchy to satisfy latency, power, availability, and quality of service requirements for one or more network slices are described. The radio access network components may include virtualized distributed units (VDUs) and virtualized centralized units (VCUs). To satisfy a latency requirement for a network slice, various components of a radio access network may need to be redeployed closer to user equipment. To satisfy a power requirement for the network slice, various components of the radio access network may need to be redeployed closer to core network components. Over time, the components of the radio access network may be dynamically reassigned to different layers within a data center hierarchy in order to satisfy changing latency requirements and power requirements for the network slice.
