Abstract: A service application programming interface (API) invoking method where a security method applied to an API exposing function entity is updated from an original security method to a new security method, and where the security method of the API exposing function entity is used for communication between the API exposing function entity and an invoker. The method includes: obtaining, by the invoker, a new security method of the API exposing function entity; and sending, by the invoker, a first invoking request to the API exposing function entity using the new security method, where the first invoking request includes a name of a service API, and where the first invoking request is used to invoke the service API.

Abstract: An address verification method and a corresponding apparatus are applied to the field of communication technologies, and in particular, relate to a short-range communication technology. During specific application, a second node receives first information from a first node. The first information includes a first to-be-resolved address and a first resolving key index that are of the first node. The first resolving key index indicates a first resolving key. Then, the second node can determine an identity address of the first node based on the first resolving key index and the first to-be-resolved address. The identity address uniquely identifies the first node. The first to-be-resolved address includes verification information for verifying the first resolving key. The first resolving key corresponds to a first identity address.

Abstract: A communication method is disclosed. The method includes: A session management function network element sends a first path establish request to a transport network control network element, where the first path establish request includes an identifier of an access network device, an identifier of a mobile gateway selected for a session, and a first transport network (TN) Quality of Service (QoS) parameter of a first QoS flow in the session, and the first TN QoS parameter of the first QoS flow is determined based on a TN QoS parameter mapped to a first service type of the first QoS flow, the access network device, and the mobile gateway. The session management function network element receives a first path establish response from the transport network control network element, where the first path establish response includes information about a first TN transmission path of the first QoS flow.

Abstract: An uplink signal transmission method includes receiving, by an active antenna unit of a base station, a first uplink signal sent by a terminal in a first band. The method also includes sending, by the base station, the first uplink signal to a first baseband processing unit of the base station corresponding to a second band for demodulation. The active antenna unit of the base station includes a first array antenna corresponding to the first band and a second array antenna corresponding to the second band. The first band is lower than the second band.

Abstract: This application provides a mode division multiplexer, which includes a metasurface of an electromagnetic resonance unit that has a plurality of sub-wavelengths disposed in an array. The electromagnetic resonance unit is configured to perform phase modulation on a beam transmitted to the electromagnetic resonance unit, to convert a spatial mode order of the beam. Because a size of the electromagnetic resonance unit is a sub-wavelength, and a pixel size of the electromagnetic resonance unit is smaller than a pixel size of a spatial light modulator in the prior art, crosstalk between different spatial modes after phase modulation performed by the mode division multiplexer is comparatively low. In this way, the crosstalk is comparatively small when beams in different spatial modes are multiplexed into a few-mode/multi-mode fiber. The mode division multiplexer in this application can implement polarization-independent phase modulation.
