Abstract: Embodiments of this application disclose a message processing method and a device, and relate to the field of communication technologies. In this way, a network device can determine a DC location that is corresponding to communication when a plurality of BWPs are simultaneously activated. A specific solution is as follows: A network device receives a first message, where the first message includes a DC location of each of M bandwidth parts BWP that are configured by the network device for a terminal; and the network device determines a DC location of current communication based on DC locations of N activated BWPs in the M BWPs, where M is an integer greater than or equal to 2, and N is an integer greater than or equal to 2 and less than M.

Abstract: Embodiments of the present disclosure disclose a mobility management method, user equipment, and a base station. The mobility management method may include: receiving, by user equipment UE in a connected mode, a source identifier of the UE from a first base station, where the source identifier is used to uniquely identify the UE in the first base station; entering, by the UE, a low-overhead state in the case that a low-overhead activation condition is satisfied, where in the low-overhead state, the UE stores a connection context of the UE in the connected mode, and camps on a cell according to a cell reselection criterion during movement; and reporting, by the UE when a first preset condition is satisfied, the source identifier to a second base station to which a second cell belongs, where the second cell is a serving cell on which the UE currently camps.

Abstract: This application provides a communication method and apparatus, and relates to the communication field, and in particular, to the multimedia broadcast multicast service (MBMS) field. The communication method includes: A main control unit receives a first data packet sent by a core network device. The main control unit sends first data included in the first data packet and first time information of the first data to a secondary unit. The secondary unit sends the first data to a terminal based on sending time indicated by the first time information. In embodiments of this application, the main control unit determines the sending time for sending the first data by the secondary unit to the terminal.

Abstract: A first apparatus establishes a first radio link control RLC entity and a second RLC entity, where the first RLC entity and the second RLC entity are associated with a first packet data convergence protocol PDCP entity. The first apparatus sends first data through the first RLC entity and/or the second RLC entity. The first RLC entity corresponds to a unicast transmission mode, and the second RLC entity corresponds to a multicast transmission mode.
