    Abstract: A communication method and a communications apparatus, where the method includes: first determining, by a terminal, a first radio access technology for establishing a Radio Resource Control (RRC) connection; and then determining, by the terminal based on access information, a first cause value for establishing the RRC connection, where the first cause value is a cause value of the first radio access technology, and the access information includes at least one of an access identity (AI), an access category (AC), or a second cause value of a second radio access technology. After the terminal determines the first cause value, the terminal sends a first message used to establish the RRC connection, and uses the first message to carry the first cause value.

    Abstract: Embodiments of this application disclose a data transmission method and a related device. The method includes: A first network device receives first indication information from a second network device, where the first indication information is used to indicate that a terminal device is successfully handed over from a third network device to the first network device or that the third network device has released a context of the terminal device; and the first network device detects a mobility problem based on the first indication information. According to the method provided in the embodiments of this application, a target SN may detect a mobility problem based on indication information sent by an MN.

    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: 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.

    Abstract: This application provides a communication processing method and apparatus. The method includes: receiving, by a target node, a second message sent by a synchronization source node via at least one intermediate node, where the second message carries a receiving time of a first message from the target node at the synchronization source node and waiting time information of the first message at each of the at least one intermediate node; and determining, by the target node, a clock deviation between the target node and the synchronization source node based on a sending time of the first message at the target node and the second message.
