US 2025/0053412 A1 · SYSTEMS AND METHODS FOR REDUCING SERVICE DOWNTIME DURING SOFTWARE UPGRADES

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.

2 more elements

A network management system for a Radio Access Network (RAN) including a first Radio Unit (RU) device, a first computing device, and a second computing device different from the first computing device, the system comprising:

one or more processors;
and
one or more storage devices storing instructions that, when executed by the one or more processors, cause the one or more processors to:
transmit first DU configuration information including an address of first RU device to the second computing device;
cause the first computing device to stop data transmission to the first RU device;
cause the first RU device to store an address of the second computing device as a value of a configuration parameter;
and
cause the second computing device to start data transmission to the first RU device.
