Embodiments are directed towards systems and methods for routing network traffic in a fifth-generation New Radio (5G NR) cellular telecommunication network radio access network (RAN) to network functions provided in a cloud service provider environment. One such method includes: configuring first virtual routing and forwarding (VRF) instances on a first router device using information that identifies the network functions and information that identifies Internet Protocol (IP) subnets; configuring second VRF instances on a second router device using information that identifies the network functions and information that identifies the subnets; controlling a first virtual private cloud (VPC) in the cloud service provider environment, the first VPC performing a first network function; and transmitting a first network packet to the first VPC using a first one of the first VRF instances and a first one of the second VRF instances.

Various arrangements of a hybrid cellular network are presented. The hybrid cellular network includes multiple base stations. Multiple subnets are created within a region of a public cloud computing platform. Each subnet can be executed at a different data center of the public cloud computing platform. Cellular network functions are instantiated within the subnets in the region of the public cloud computing platform. Multiple virtual routers that manage the routing of packets for the cellular network functions are created within the subnets.

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.

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

Automated processes, computing systems, devices and other aspects of a wireless data network are described. 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) and/or layer two (L2) switch. The dummy messages 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.
