The present invention belongs to the field of communications technologies, and discloses a radio controller upgrade method and a device. The method includes: determining, by a first radio controller RNC to be upgraded, a second RNC from multiple secondary homing RNCs, where the first RNC provides a service for a base station, and the multiple secondary homing RNCs maintain transmission links with the base station; switching, by the first RNC, control over the base station to the second RNC, so that the second RNC sends a cell setup message to the base station according to a cell parameter configured on the second RNC, so that the base station switches control over an established cell to the second RNC; and when the control over the cell established by the base station is switched to the second RNC, performing, by the first RNC, an upgrade procedure. In the present invention, another RNC can continue to provide a service in an upgrade process, and a hitless service is ensured in the upgrade process without hardware redundancy configuration. In addition, because quick switching consumes a short time, an annual interruption time of a service of an RNC is reduced, and system reliability is improved. |
