Abstract

A method, an apparatus, and a system for detecting a radio network problem are disclosed. The method includes: when a radio network problem occurs on a user equipment (UE), a first base station controlling a cell that a radio resource control (RRC) connection established with the UE, receives problem information about the radio network problem sent by the UE, in a procedure of re-establishing the RRC connection by the UE, and sends the problem information to a second base station controlling a cell where the radio network problem occurs. In this way, the network side can automatically identify and detect the radio network problem which occurs on the UE, so that the network can perform self-adjustment and optimization, therefore improving the network performance and satisfying use requirements of users.
