Abstract: The present disclosure discloses a method and apparatus for processing information. The method for processing information comprises: retrieving, by a first base station, user context information of a User Equipment (UE) from a second base station by initiating a procedure to the second base station for retrieving the user context information, wherein the user context information doesn't include user history information; updating, by the first base station, bearer path information and resuming the user context information by initiating a path switch request message to a device in a core network; and performing, by the first base station, one or more of the following operations after the UE resumes to a connected state: re-starting to collect user history information, and re-retrieving user history information from the UE through an air interface.
