    Abstract: In a communication method, a policy control network element receives first information from a terminal device, where the first information is a banned application identifier, a banned PSI, a URSP identifier, or an allowed application identifier. The policy control network element obtains a first URSP of the terminal device from a data storage network element. The policy control network element determines a second URSP of the terminal device based on the first information and the first URSP. Based on this solution, when deciding a URSP of the terminal device, the policy control network element considers the first information reported by the terminal device, so that a proper URSP can be determined for the terminal device. In addition, this helps avoid signaling overheads caused because the terminal device and a policy control network element side continuously update and maintain a URSP that the terminal device does not need to use.

    Abstract: A communication method is provided, a first policy control network element sends a subscription message to a usage monitoring network element, where the subscription message includes identification information of a first slice and identification information of a terminal device, and the subscription message is for subscribing to usage status information of the terminal device in the first slice. The first policy control network element receives, from the usage monitoring network element, first indication information indicating that usage of the terminal device in the first slice is exhausted. The first policy control network element sends, to a mobility management network element, availability status information of the first slice indicating that the first slice is unavailable; or the first policy control network element sends a user route selection policy to the terminal device, where the user route selection policy does not include the identification information of the first slice.

    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: Embodiments of this application provide a communication method and apparatus, and a device. The method includes: A network device determines first user slice information of a first user. The network device sends the first user slice information to a terminal device, where the terminal device is a terminal device used by the first user, and a user slice indicated by the first user slice information is a user slice used by the first user. This improves flexibility of performing communication by using a network slice.

    Abstract: A method for determining a network quality of service (QoS) flow, a network element, and a system include receiving, by a session management function network element, a policy and charging control (PCC) rule from a policy control function network element, where the PCC rule includes QoS parameters, the QoS parameters include standardized QoS parameter indication information and a non-standardized QoS parameter, and the non-standardized QoS parameter includes at least one attribute comprised in a standardized QoS parameter corresponding to the standardized QoS parameter indication information and a corresponding value of the at least one attribute, and determining, by the session management function network element based on the standardized QoS parameter indication information and the non-standardized QoS parameter, a QoS flow corresponding to the PCC rule.

    Abstract: In a location change reporting method, a session management function entity receives from a mobility management entity information including location change information of UE in a first presence reporting area (PRA), an identity of the first PRA, and an identity of a PRA set that includes the first PRA. The session management function entity identifies, based on the identity of the PRA set and locally stored PRA subscription information, a subscription entity that subscribes to location change events of the UE in the PRA set, and sends the identity of the first PRA and the location change information of the UE in the first PRA to the subscription entity.
