Method and apparatus for re-establishing radio link

摘要

The disclosure provides a method and an apparatus for re-establishing a radio link. The method comprises: a destination base station receiving a re-establishment request message sent by a User Equipment (UE), a cell identifier and an identifier of the UE are carried in the re-establishment request message, and attribute information used for indicating UE handover success or handover failure is carried in the cell identifier and the identifier of the UE (S102); and the destination base station determining, according to the attribute information, a security algorithm applied to radio link re-establishment between the destination base station and the UE, and establishing a radio link using the security algorithm (S104). The disclosure solves the problem in the related art that the radio link re-establishment fails as a security algorithm fallback process fails, thereby improving the success rate of radio link re-establishment.
