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: Various arrangements for updating a radio unit (RU) of a cellular network are presented. A volume of cellular signals being handled by a first programmable processor of the RU and a second programmable processor of the RU may be analyzed. A determination can be made that one of the processors has sufficient available resources to handle the analyzed volume of cellular signals. The RU can cause cellular signals to be rerouted to one of the programmable processors while the other processor is taken offline for updating. The update process is performed such that UE in communication with the RU experience uninterrupted cellular network access.

Abstract: Example embodiments are directed towards detecting a failure of a fifth-generation New Radio (5G NR) cellular telecommunication network containerized network function (CNF) running within a dedicated node group of cloud compute instances hosting a plurality of CNFs of a wireless telecommunication service provider or a failure of a specific cloud compute instance hosting the CNF within the node group. In response to the detection of a failure of the CNF within the node group or a failure of the specific cloud compute instance hosting the CNF within the node group, automatically switching to host the CNF on a spare cloud compute instance within the node group dedicated to the wireless telecommunication service provider and pre-provisioned to host CNFs of a same type as the CNF for the wireless telecommunication service provider.

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 managing user experiences during a cellular telecommunication network outage involving network communication failure detection and performing different recovery actions in response to detecting a failure in communication between certain telecommunication network components and/or failure of certain network links. For example, the system may perform different recovery actions in response to the failure in communication being due to a detected inactive network link to the central unit control plane (CU-CP) versus the CU-CP itself being initially indicated as inactive

Abstract: Disclosed is creation of a very narrow bandwidth part (BWP), referred to herein as a virtual BWP. The virtual BWP is created within an operating channel that is not supported by 3rd Generation Partnership Project (3GPP) current standards (e.g., below 5 MHz). This enables a wireless network to be even more flexible in supporting a variety of use cases. In particular, the network artificially creates a small virtual BWP and assigns it to users without requiring any explicit signaling to the user for creating the virtual BWP. The virtual BWPs will limit the physical downlink control channel (PDCCH), the physical downlink shared channel (PDSCH) data region, the physical uplink control channel (PUCCH) and the physical uplink shared channel (PUSCH) for a given user which can be associated with slicing.
