Abstract: The present invention discloses a service instance mapping method, apparatus and system. The service instance mapping method includes: correlating a layer-2 service instance with a service access port of the service instance, and determining correspondence between the service access port and a service instance identifier; and mapping the service instance identifier to a service label of a packet. In embodiments of the present invention, because the service label is adopted to carry the service instance identifier, a higher service label supporting capability may be included, more service instances may be supported, and a multi-tenant requirement in a large-scale public cloud environment can be met; control protocol support is extended, and extension of a TRILL protocol can fulfill a higher service development capability.

Abstract: A communication method and a communications device, where the communication method includes: When a user equipment roams from a first network to a second network, a first core network device receives a first request, where the first request is a user authentication request or an authentication data request, where the first request carries an authentication vector request indication, where the second network is a 5G standalone network, where the first network is a 5G non-standalone network, and where the first core network device is in the first network. The first core network device generates an authentication vector quintet based on the authentication vector request indication, where a 0th bit of an authentication management field in the authentication vector quintet is set to 1. The first core network device sends a response to the first request, where the response to the first request carries the authentication vector quintet.

Abstract: This application provides a method and an apparatus for creating a virtualized network function instance VNFI. The method includes: generating, by a hardware-mediated execution enclave HMEE in a network functions virtualization NFV system, a private-public key pair, where a to-be-instantiated VNFI is deployed in the NFV system, and the HMEE and a to-be-instantiated first virtualized network function component VNFC are deployed in the VNFI; sending a public key in the private-public key pair to a security control device; receiving an encrypted security credential from the security control device, where the encrypted security credential is obtained by encrypting a security credential of a package of the first VNFC based on the public key, and the security credential is used to decrypt the package of the first VNFC; and decrypting the encrypted security credential based on a private key in the private-public key pair, to obtain the security credential.

Abstract: In an identity verification method for a network function service, a network element receives from a requesting network element a network function (NF) service request that includes a token, The token includes first certificate information. The network element verifies the first certificate information to determine whether an identity represented by the first certificate information is consistent with an identity of the requesting network element. When the network element determines that the identity represented by the first certificate information is inconsistent with the identity of the requesting network element, the network element rejects the NF service request.

Abstract: This application provides a wireless communication method and apparatus. The wireless communication method includes: A first device obtains first information, where the first information includes a correspondence between first customer premise equipment and at least one first terminal device, and a correspondence between the first terminal device and at least one second terminal device. The first device configures the first information on a second device, where the first information is used by the second device to verify that a received service packet is a service packet sent by the first terminal device to the second terminal device by using the first customer premise equipment. Therefore, accuracy of service packet transmission of an industrial terminal device can be ensured, an industrial terminal or customer premise equipment can be prevented from being attacked to some extent, a loss caused by the attack on the device is reduced, and information security of the industrial terminal device in an industrial field network and an entire industrial field network is improved.

Abstract: A vehicle driving intention prediction method includes that a road intention and a lane intention of a target vehicle are determined based on a driving feature of a surrounding vehicle relative to the target vehicle, a driving feature of the target vehicle relative to a road, and a driving feature of the target vehicle relative to a lane, and then a driving intention of the target vehicle is determined based on the road intention and the lane intention of the target vehicle. The driving intention of the target vehicle is determined by predicting a multi-level intention, for example, the lane intention or the road intention, of the target vehicle.
