Abstract

The present invention provides a method for obtaining radio access network information and a radio access network controller. The method for obtaining radio access network information includes: receiving, by a second radio access network controller, first radio access network information request information from a first radio access network controller, where the first radio access network information request information is used to request radio access network information of a third radio access network controller; and sending, by the second radio access network controller, target radio access network information to the first radio access network controller. The method reduces resource waste, improves a resource utilization rate and reduces a burden on a source core network entity and a target core network entity.
