Abstract: This application relates to communication technologies, and provides a channel key-based encryption method and an apparatus, to resolve a problem that a terminal cannot avoid an attack from a false base station before a security mode is enabled, and a security risk. The method includes: A network device broadcasts a system information block, indicating that channel key generation is supported, where the system information block includes a preamble and a resource configuration of a physical random access channel; receives, on the physical random access channel, a first message from a user equipment, where the first message includes the preamble; sends a second message to the user equipment, where the second message includes configuration information of a first time-frequency resource; receives, on the first time-frequency resource, a third message from the user equipment; and performs channel measurement based on the third message, to obtain a channel key.

Abstract: Embodiments of this application provide a packet transmission method, a communication apparatus, and a communication system. A target transport layer proxy network element establishes a fourth transport layer connection based on a first context of a source transport layer proxy network element, where the first context is a context about packet transmission of the source transport layer proxy network element on a first path. If the target transport layer proxy network element receives first indication information, and the first indication information indicates that application context migration between a first application server and a second application server is completed, the target transport layer proxy network element performs transport layer processing on a packet on a second path based on a second context of the target transport layer proxy network element, and transmits, on the second path, a packet obtained through the transport layer processing. Hence, a packet loss can be avoided.

Abstract: A communication method and apparatus are provided. The method may include: A mobility management network element receives a transaction identifier of a remote terminal device and a name of a data network from a relay terminal device. The mobility management network element determines a subscription permanent identifier of the remote terminal device based on the transaction identifier, and then sends the subscription permanent identifier and the name of the data network to a session management network element. After receiving the subscription permanent identifier and the name of the data network, the session management network element determines, by using a data management network element based on the subscription permanent identifier and the name of the data network, whether to perform secondary authentication on the remote terminal device. Whether to perform secondary authentication on the remote terminal device can be determined by using the provided solution.

Abstract: This application provides a communication method and apparatus, and relates to the communication field, to ensure proximity based service relay communication security. In the method, proximity based service authentication information #1 provided by a data management network element is used, so that a remote terminal and a network may authenticate each other and generate a proximity based service key used for communication between the remote terminal and a relay terminal. Further, the remote terminal device and the relay terminal device derive a communication protection key for a PC5 connection (namely, a connection between the remote terminal and the relay terminal) based on the proximity based service key, which may include at least one of an encryption key and an integrity protection key, so that proximity based service relay communication security is ensured, and a case such as user information leakage caused by an attack is avoided.

Abstract: This application provides a communication method and apparatus. The method includes: A first network element receives a first request message from a second network element, where the first request message is used to request to perform a first operation on a first terminal device. The first network element determines, based on the first request message, whether the second network element is authorized to request to perform the first operation on the first terminal device. Whether a network element that sends a request message is authorized to request to perform a related operation is verified, to determine whether the network element is an attacker. This reduces impact on a system service resulting from requests of an attacker and improves system security.

Abstract: The present disclosure provides example traffic routing methods, apparatuses, and systems. One example method includes determining, by a session management network element, a routing rule, where the routing rule indicates a first traffic steering entity to send a first traffic to a first function entity, or send a second traffic to a second function entity or an access device, where the first traffic is a traffic on which first traffic steering control is to be performed, and the second traffic is a traffic on which the first traffic steering control has been performed. The routing rule is sent by the session management network element to the first traffic steering entity in a session management process.
