Abstract: The mobility management network element performs security protection on a paging identity of a terminal device by using a security context obtained by negotiating with the terminal device, to obtain a first paging identity, and sends a first paging message to a base station. The base station sends a second paging message to the terminal device, where the second paging message carries the first paging identity and first indication information, and the first indication information is used to indicate that the first paging identity is a security-protected paging identity. The terminal device performs security verification on the first paging identity by using the security context based on the first indication information, to obtain a second paging identity, and processing the second paging message based on the second paging identity and an identity of the terminal device.

Abstract: A user equipment (UE) capability reporting method and apparatus to improve a success rate of UE rollback configuration to a CA mode and improve transmission bandwidth of UE. The UE may report, based on received first capability enquiry request information, second capability enquiry request information, and multi-RAT request condition, a second band combination in a first RAT and a second multi-RAT band combination in the first RAT and a second RAT. The second multi-RAT band combination, which meets the multi-RAT request condition, is used to configure the UE to be in a multi-RAT multi-connectivity mode of the first RAT and the second RAT. In a process in which the UE reports the second band combination, the UE preferentially reports a first CA band combination.

Abstract: This application discloses a wireless communication method, apparatus, and system, to ensure service quality of terminal communication in a non-standalone NSA networking architecture. The wireless communication method includes: starting, by a terminal, RRC connection establishment with an NR cell based on an indication of a network device, and starting a timer based on a quantity of RRC connection establishment failures of the NR cell, where the timer is set to first duration. Within the first duration, when the network device indicates the terminal to report measurement results of the NR cell and another cell, the terminal only reports the measurement result of the other cell, but does not report the measurement result of the NR cell.
