Abstract: Example methods and apparatuses are provided. An example method includes receiving first indication information. The first indication information indicates that a trajectory of a first terminal device matches a trajectory of a second terminal device. The method further includes sending second indication information to the first terminal device. The second indication information indicates to change a trajectory information reporting periodicity to a second periodicity, or the second indication information indicates to suspend trajectory information reporting. The second periodicity is greater than a first periodicity, and the first periodicity is the trajectory information reporting periodicity before the first indication information is sent.

Abstract: Embodiments of this application provide an information transmission method, an apparatus, and a system. A first network device sends, to a terminal device, conditional handover configuration information that includes information about candidate cells and a handover trigger condition; after receiving the conditional handover configuration information and performing a conditional handover, the terminal device sends, to a second network device, a first failure cause value corresponding to a candidate target cell and/or a second failure cause value corresponding to a to-be-determined cell during the conditional handover; and the second network device receives the first failure cause value and/or the second failure cause value from the terminal device, and sends the first failure cause value and/or the second failure cause value to the first network device.

Abstract: This application provides a communication method and apparatus, and relates to the field of communication technologies. The method may include: A network device performs integrity protection on system information by using a first private key, and sends the system information, where the system information includes a first public key corresponding to the first private key and/or an index of the first public key. Correspondingly, a terminal device receives the system information from the network device, and if determining that the first public key is valid, the terminal device verifies integrity of the system information by using the first public key. According to this method, on one hand, the terminal device can effectively identify validity of the system information. On the other hand, because the system information includes the first public key and/or the index of the first public key, flexible update of an asymmetric key can be implemented.

Abstract: This application provides a communications method and a communications apparatus, to reduce storage resources required by an access network device to store a context of a terminal device. The method includes: The access network device gathers terminal devices that have a same attribute in a group, where a context of each terminal device is divided into two parts: a common context and a dedicated context, the common context is shared by all the terminal devices in the group, and the dedicated context is a context specific to the terminal device. The access network device stores one common context for each group and stores a dedicated context of each terminal device in the group, to maintain the context of each terminal device.
