Abstract: This application provides a communication method and a communication apparatus. In a multiple connectivity mobility scenario, a terminal device records information related to a secondary network device mobility process to generate a mobility report, and sends the mobility report to a network device. The network device determines, based on content in the mobility report, whether a mobility parameter related to the SN mobility needs to be adjusted. If the mobility parameter needs to be adjusted, the network device performs proper adjustment, thereby improving robustness of secondary network device mobility of the terminal device.

Abstract: A communication method and apparatus are disclosed. After receiving, from a source network device, a first message that enables a terminal device to handover from the source network device to a target network device, maintaining data transmission with the source network device; and sending a first report in response to subsequently detecting that a connection between the terminal device and the source network device fails. The first report includes first indication information used to determine whether the connection between the terminal device and the source network device fails before the terminal device accesses the target network device. In this way, the network device identifies, based on the information, a potential handover scenario that has a problem, so that a handover parameter is better adjusted or handover is more properly triggered, thereby improving a handover success rate of the terminal device.

Abstract: Embodiments of this application provide a communication method, apparatus, and system. The method includes: determining, based on area configuration information of a first cell of a network device and location information of a terminal device, a first sub-area corresponding to the terminal device, where the area configuration information indicates information about a plurality of sub-areas corresponding to the first cell, and the plurality of sub-areas include the first sub-area; and obtaining satellite ephemeris information corresponding to the first sub-area. In the foregoing solution, the sub-area is introduced, and the terminal device only needs to obtain the satellite ephemeris information corresponding to the sub-area in which the terminal device is located. This reduces an amount of satellite ephemeris information obtained by the terminal device, and therefore can reduce overheads of the terminal device.

Abstract: Embodiments of this application disclose a paging collision processing method and a related apparatus. The method includes: When a terminal device detects that a paging occasion of the terminal device in a first camped cell collides with a paging occasion of the terminal device in a second camped cell, the terminal device may determine a first paging parameter, and may send first information including the first paging parameter to a first network device corresponding to the first camped cell. The first network device sends second information including a second paging parameter to the terminal device. The terminal device determines a second paging occasion of a first identity module card of the terminal device in the first camped cell based on the second paging parameter in the received second information. The terminal device monitors a paging message in the first camped cell on the second paging occasion. The second paging occasion does not overlap a third paging occasion of a second identity module card of the terminal device in the second camped cell in terms of time. According to embodiments of this application, a paging collision that occurs when the terminal device monitors the paging message can be avoided.
