User equipment, a base station, a base station access method, and a radio link monitoring method are provided, where the user equipment includes: a first receiving module, configured to receive first indication information sent by a first base station, where the first indication information includes a time period required by the user equipment to initially request to access a second base station, or includes a preset first maximum quantity of times the user equipment sends random access scrambling code to a second base station when the user equipment initially requests to access the second base station; a first sending module, configured to send the random access scrambling code to the second base station; and a first notification module, configured to: if the user equipment fails to access the second base station within the time period, or if a quantity of times the user equipment sends the random access scrambling code to the second base station when the user equipment initially requests to access the second base station is greater than the first maximum quantity of times, notify the first base station that a secondary cell group failure occurs. In this application, efficiency of accessing the second base station by the user equipment is improved by limiting a time in which the user equipment requests to access the second base station or a quantity of times of sending the random access scrambling code in initial and subsequent access. |
