    Abstract: This application provide an information update method, and related communications apparatus. In this solution, a first network device determines first information, and sends the first information to a second network device. After receiving the first information, the second network device updates, based on the first information, configuration information corresponding to a first candidate cell to obtain configuration information corresponding to a second candidate cell. The first information is used to update the configuration information corresponding to the first candidate cell to obtain the configuration information corresponding to the second candidate cell, both the first candidate cell and the second candidate cell are managed by the second network device, the first candidate cell includes at least one cell, and the second candidate cell includes at least one cell.

    Abstract: A random access method includes working, by a user equipment (UE), on a first bandwidth part (BWP), where the first BWP is a currently active BWP, when the UE needs to perform a random access procedure, the UE performs the random access procedure on an initial BWP or on the first BWP, and when the UE receives BWP switching indication information from a network device instructing the UE to use a second BWP when performing the random access procedure on the first BWP, continuing, by the UE, to perform the random access procedure on the first BWP, or stopping, by the UE, performing the random access procedure on the first BWP, and performing the random access procedure on the second BWP.

    Abstract: A handover method, including sending, by a source base station to a source core network device in a process of handing user equipment (UE) over from the source base station to a target base station, a handover required message. The message comprises identification information of a target core network device, and the identification information of the target core network device instructs the source core network device to perform a core network relocation process with the target core network device. The source base station is connected to the source core network device, and the target base station is connected to both the source core network device and the target core network device.

    Abstract: A method, a base station, and a system for sending radio resource control (RRC) signaling are provided. The method includes a pico base station and a macro base station participate in configuration and generation of an RRC reconfiguration message; the pico base station establishes only one RRC entity that is used to generate a configuration parameter or an RRC entity; the RRC reconfiguration message cooperatively generated by the pico base station and the macro base station is uniformly sent by the macro base station to a user equipment (UE). According to the application, the UE can support an RRC reconfiguration message sent by the pico base station, only by establishing a signaling radio bearer (SRB) corresponding to the macro base station. Accordingly, design complexity and costs are lowered.

    Abstract: Example communication methods and apparatus are described. In one example method, a first access network device obtains core network load information, where the core network load information indicates at least one of load of a first core network element or load of a second core network element. The first access network device determines, from the first core network element and the second core network element based on the core network load information, a core network element serving a terminal device.
