Abstract: Example wireless communication methods and apparatus are described. One example method includes a terminal initiates a reestablishment procedure when a handover procedure of the terminal fails. When a base station reselected by the terminal is a base station (that is, a target base station) to which the terminal is handed over in a handover procedure, and because a key of the base station is updated in the handover procedure, the base station includes key derivation information in a reestablishment message to be sent to the terminal. Therefore, the terminal can update a key of the terminal based on the key derivation information, so that the key of the terminal can be consistent with the key of the base station.

Abstract: This application provides a method for restricting access of a terminal device, and an apparatus. The method includes: receiving, by an access network device, a first identifier that is from a terminal device, where the first identifier is used to identify the terminal device; and if the first identifier matches a second identifier, restricting, by the access network device, access of the terminal device, where the second identifier is used to identify a terminal device having abnormal behavior. Based on the solution, the access network device pre-records the second identifier of the terminal device having the abnormal behavior.

Abstract: This application provides a key derivation algorithm negotiation method and an apparatus. The method includes: checking, by a terminal, a sent first key derivation algorithm and a received second key derivation algorithm; if the checking is correct and the first key derivation algorithm is the same as the second key derivation algorithm, determining that the first key derivation algorithm sent by the terminal is not tampered with by an attacker; and then using a negotiated third key derivation algorithm as a key derivation algorithm of the terminal, to ensure confidentiality of the negotiated key derivation algorithm, thereby improving communication security.

Abstract: This application provides a congestion control method and an apparatus. According to the method, a control node may determine that a data processing node is in a congested state, where the data processing node is configured to process data sent by a terminal apparatus. The control node may send a first message to a first terminal apparatus corresponding to a terminal apparatus identifier in a list stored in the control node. The first terminal apparatus identifier in the list is of the first terminal apparatus in a first terminal apparatus abnormal state. The first terminal apparatus identifier is received by the control node. The first message indicates to release a user plane connection, and the user plane connection is used to transmit data of the first terminal apparatus.

Abstract: A link re-establishment method, an apparatus, and a system are provided. 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.
