    Abstract: Disclosed is a method of operating a Radio Access Network (RAN) including a Radio Unit (RU), a first Distributed Unit (DU), a second DU that functions as a dynamic standby DU, and a network management device. After the RU transmits data to the first DU using a configuration parameter set to an address of the first DU, the RU detects an outage of the first DU. In response to detecting the outage, the RU transmits to the network management device a message indicating detection of the outage. In response, the network management device configures the second DU to perform the functions of the first DU, and causes the second DU to request the RU to set the configuration parameter to an address of the second DU. The RU then uses the configuration parameter set to the address of the second DU to transmit data to the second DU.

    Abstract: A method for performing a software update that reduces down time in a Radio Access Network (RAN) is disclosed. A first computing device receives first Distributed Unit (DU) configuration information including an address of a first radio unit (RU) device. The first computing device cause the first RU device to stores an address of the first computing device as a value of a configuration parameter. After a second computing device installs software, the second computing device receives the first DU configuration information including the address of the first RU device. The first computing device receives an instruction to stop data transmission to the first RU device. The second computing device causes the first RU device stores an address of the second computing device as the value of the configuration parameter. The second computing device receives an instruction to start data transmission to the first RU device.

    Abstract: When a failed connection is detected from a first radio unit (RU) to the cellular site router (CSR), activation of an existing backup cabled connection from the first RU to the CSR through a cabled connection between the first RU and a second RU of the cellular telecommunications tower may be performed. In one example, a first RU and second RU each have two physical network ports. The activation of the existing backup cabled connection from the first RU, via the second RU, to the CSR may include causing the first RU to enter from a normal operating mode into an Open Radio Access Network (O-RAN) cascade operating mode to attempt to attain network connectivity for the first RU using the second physical network port of the first RU.

    Abstract: Disclosed is a method of operating a Radio Access Network (RAN) including a Radio Unit (RU), a first Distributed Unit (DU), a second DU that functions as a dynamic standby DU, and a network management device. After the RU transmits data to the first DU using a configuration parameter set to an address of the first DU, the RU detects an outage of the first DU. In response to detecting the outage, the RU transmits to the network management device a message indicating detection of the outage. In response, the network management device configures the second DU to perform the functions of the first DU, and causes the second DU to request the RU to set the configuration parameter to an address of the second DU. The RU then uses the configuration parameter set to the address of the second DU to transmit data to the second DU.
