Abstract: Embodiments of this application relate to the field of communication technologies, and disclose a communication method and apparatus, so that corresponding PDCP entities of a first terminal and a second terminal use consistent input parameters when executing security algorithms, thereby ensuring normal communication on a sidelink SL and improving communication reliability. A specific solution is as follows: A first terminal determines a logical channel identifier LCID meeting a preset condition, where a first packet data convergence protocol PDCP entity of the first terminal is associated with two or more logical channels LCHs; the first terminal receives a first data packet from a second terminal; and the first PDCP entity of the first terminal parses the first data packet based on the LCID.

Abstract: Embodiments of this application disclose a device identification method and a related apparatus, to reduce costs of identifying whether a device that accesses a network is an AP device. The method in the embodiments of this application includes: when a type of the device that accesses the network needs to be identified, obtaining a MAC address of the access device, and obtaining a MAC address of a Wi-Fi hotspot around a network access device; and then comparing the MAC address of the access device with the MAC address of the Wi-Fi hotspot, and determining, if the MAC address of the access device and the MAC address of the Wi-Fi hotspot belong to a same address segment, that the access device is an AP device.

Abstract: This application provides a data transmission method and a apparatus. The method includes: when determining that a first data stream satisfies a transmission optimization enabling condition, a first transmitting end TE1 sends a transmission optimization enabling notification to a first receiving end RE1, where the transmission optimization enabling notification is used to indicate the RE1 to skip sending, to the TE1, an acknowledgment packet used to acknowledge that a data packet of the first data stream is already received by the RE2. The TE1 receives a data packet Data2 in a second protocol format from the TE2. The TE1 sends a data packet Data1 in a first protocol format to the RE1. The TE1 receives an acknowledgment frame Ack1 in the first protocol format from the RE1. The TE1 constructs an acknowledgment packet Ack2 in the second protocol format based on the Ack1, and sends it to the TE2.

Abstract: Embodiments of this application provide a security protection method, a device, and a system, to improve data transmission security. The method includes: determining, by a terminal, a session management network element, or a mobility management network element, whether a security protection policy determined by an access network device is consistent with a user plane security policy delivered by the session management network element to the access network device; and if the security protection policy determined by the access network device is inconsistent with the user plane security policy delivered by the session management network element to the access network device, performing processing according to a preset policy.

Abstract: Embodiments of the present disclosure disclose a network roaming protection method and related device. The method includes: receiving, by a visited session management device, a first session establishment request that includes a first security requirement; obtaining, by the visited session management device, a target security policy, where the target security policy is obtained by processing the first security requirement set and a second security requirement set using a preset rule; and sending the target security policy to the UE instructing the UE to generate a target shared key based on a reference shared key and according to a rule defined by the target security policy, where the target shared key is used to protect secure end-to-end data transmission between the UE and the visited gateway.

Abstract: This application provides a key configuration method and an apparatus. A key management center obtains a service key, and performs encryption and/or integrity protection on the service key to obtain a token. The key management center sends the token to a first network element, the first network element forwards the token to a second network element, and the second network element obtains the service key based on the token. The service key is used to perform encryption and/or integrity protection on data transmitted between the first network element and the second network element. Therefore, security key configuration can be implemented through interaction between the key management center and the network elements, thereby laying a foundation for end-to-end security communication between the first network element and the second network element.
