Abstract: This application relates to the field of wireless communications technologies, and in particular, to a communication method, apparatus, and system. This application provides a communication method. The method includes: a user equipment sends a first message to a secondary base station, where the first message is used to indicate that an exception occurs on a connection between the user equipment and a master base station; and the user equipment receives a second message sent by the secondary base station, where the second message is used to indicate whether to recover the connection to the master base station. This aims to quickly recover the connection between the user equipment and the master base station through interaction between the user equipment and the secondary base station, thereby reducing interruptions of data transmission and/or signaling transmission, and further improving system performance and user experience.

Abstract: The present disclosure relates to connection reestablishment methods and apparatus, in one example method, when a handover fails, a terminal reverts back to a source configuration, and obtains a selected cell. The terminal sends a connection reestablishment request to a selected radio access network device. The terminal receives a first message from the selected radio access network device, where the first message includes indication information used to indicate to derive an access network key based on a core network key. The terminal obtains a first core network key based on the indication information, and derives a first access network key based on the first core network key. The terminal communicates with the selected radio access network device by using the first access network key.

Abstract: Embodiments of the present disclosure provide a downlink synchronization method, an apparatus, and a system, and relate to the communications field, so as to reduce downlink synchronization complexity and improve downlink synchronization efficiency. According to the downlink synchronization method, abase station sends downlink synchronization reference information to UE by using dedicated signaling or a system message, where the downlink synchronization reference information is used to instruct the UE to perform downlink synchronization in a second cell by referring to a downlink synchronization channel of a first cell; and the base station sends, in the second cell according to location information of the UE, a beam including a downlink synchronization channel to the UE, where the first cell and the second cell include an overlapped coverage area. The embodiments of the present disclosure are applied to synchronization channel sending.

Abstract: The present invention relates to a multimedia broadcast multicast communication method, an apparatus, and a system. The method includes: receiving, by a base station, first indication information at a first time, where the first indication information is used to indicate that transmitting service data in a multimedia broadcast multicast service MBSFN manner is to be suspended; and sending, by the base station, second indication information to user equipment UE according to the first indication information, so that the UE suspends, at a second time according to the second indication information, receiving the service data in the MBSFN manner. The first time is earlier than the second time, and duration between the first time and the second time is less than a multicast control channel MCCH modification period. The user equipment is notified in a more timely manner to suspend transmitting the service data in the MBSFN manner.

Abstract: This application discloses a method for a handover of a mobile station between a source base station and a target base station. The target base station receives a handover request message from the source base station. The handover request message includes quality of service (QoS) information of the mobile device, radio bearer identifier information of the source base station, and a first mapping relationship between a flow and a radio bearer of the source base station. The target base station sends a handover acknowledgement message to the source base station.
