Abstract: Embodiments of this application disclose a security policy processing method, to implement a best-effort on-demand user plane security activation mechanism in a network in which there is a core network element that does not support on-demand user plane security protection. The security policy processing method in embodiments of this application includes: A target 1 receives a message #50-2 from a core network device #30-1, where the message #50-2 includes container information from a source access network device. The target access network device determines a user plane security activation status between the target access network device and a terminal device based on the message #50-2, where the user plane security activation status indicates whether user plane ciphering protection is activated and/or whether user plane integrity protection is activated.

Abstract: This application relates to the field of communications technologies, and provides a communications method and apparatus, to reduce a data transmission latency between an IAB node and an IAB donor. The method includes: An IAB node receives an uplink data packet from a terminal; the IAB node determines a PDCP layer security status of the uplink data packet; the IAB node determines a target secure tunnel from a plurality of secure tunnels between the IAB node and an IAB donor based on the PDCP layer security status of the uplink data packet; and the IAB node sends the uplink data packet to the IAB donor through the target secure tunnel. This application is applicable to a data transmission process.

Abstract: The present disclosure relates to connection reestablishment methods and apparatus, in one example method, when a handover fails, a terminal reverts back to a source configuration, and obtains a selected cell. The terminal sends a connection reestablishment request to a selected radio access network device. The terminal receives a first message from the selected radio access network device, where the first message includes indication information used to indicate to derive an access network key based on a core network key. The terminal obtains a first core network key based on the indication information, and derives a first access network key based on the first core network key. The terminal communicates with the selected radio access network device by using the first access network key.

Abstract: This application provides a method for controlling a connection between a terminal and a network, and an apparatus. The method includes: receiving, by a terminal, a packet filter; and discarding, by the terminal, an uplink data packet matching the packet filter. Based on this solution, a connection can be blocked near a source (that is, the connection is blocked from the terminal), to reduce traffic exchanged between the terminal and a user plane network element. Compared with an existing technical solution, the terminal implements traffic control to reduce a quantity of uplink data packets sent to the user plane network element, thereby reducing load of the user plane network element.

Abstract: The present disclosure discloses a link re-establishment method, an apparatus, and a system. The method includes: obtaining, by user equipment UE, a MAC of the UE based on a NAS integrity key and a first MAC generation parameter, where the first MAC generation parameter includes an identifier of the UE; sending, by the UE, a re-establishment request message to a target RAN, where the re-establishment request message includes the MAC and the first MAC generation parameter; and receiving, by the UE, a re-establishment response message of the target RAN. The UE triggers, by sending the re-establishment request message, a CP functional entity to perform authentication on the UE. This resolves a prior-art problem that an excessively long time is consumed to re-establish a connection to a target RAN by using an RAU procedure, increases a speed of re-establishing a connection between UE and a network, and improves user experience.

Abstract: This application provides example key management methods and example communication apparatuses. In an example method, a terminal device obtains identification information of a first decryption network element in a local network. The terminal device obtains, based on the identification information and a mapping relationship, a first encryption key corresponding to the first decryption network element, where the mapping relationship indicates at least one decryption network element and an encryption key corresponding to each of the at least one decryption network element, and the at least one decryption network element includes the first decryption network element. The terminal device encrypts the user identity information by using the first encryption key, to obtain a hidden user identity. The terminal device sends a registration request to the local network through an access network device, where the registration request includes the hidden user identity.

Abstract: This application provides security activation methods and communication apparatuses. In an example method, a first access network device in a first communication standard requests a second access network device in a second communication standard to allocate a resource for dual connectivity of a terminal device, and sends, to the second access network device, a user plane security policy. The first access network device further receives identification information of a bearer and a security activation status from the second access network device and sends the identification information of the bearer and the security activation status to the terminal device.
