Abstract: This application provides a communication method and apparatus. The communication method includes: A network device sends a first message to a first terminal device UE, where the first message includes information about a first resource, and the first resource is to be used to transmit a second message; and when the network device receives the second message from the first UE by using the first resource, the network device determines that the first UE is not faulty, where the second message indicates that the first UE is not faulty. Therefore, the network device may determine, based on the second message sent by the first UE, that the first UE is not faulty. This ensures that service reliability is not affected by a fault of a terminal device, avoids forced termination of service transmission, and ensures transmission reliability.

Abstract: Embodiments of this application provide an identification method and apparatus. The method includes: A first device sends a first command to at least one device, where the at least one device includes a second device, the first command is used to obtain first prefix information, the first prefix information includes k bits, and k is an integer greater than or equal to 1. The first device receives a first random number from the second device, where the first random number corresponds to the first prefix information. The first device determines, based on the first random number, that the second device accesses the first device. This application provides the method for identifying the second device by the first device. This can identify the second device, and implement inventory and random access of the second device.

Abstract: This application provides a communication method and apparatus, to resolve a problem that security is low when a tag is triggered to perform random access in a communication network. The method includes: receiving first signaling, and determining, based on the first signaling, a second mask stored at a first storage location; and performing random access when a first mask matches the second mask. The first signaling indicates the first storage location and the first mask, the first signaling carries a first mask identifier, and the first mask identifier identifies the first storage location and/or the first mask. In embodiments of this application, a correspondence between a mask identifier and a storage location and/or a correspondence between the mask identifier and a mask are/is negotiated in advance, so that a part or all of masks and storage locations can be implicitly indicated by using a mask identifier.

Abstract: Example data scheduling methods and apparatus are described. One example method includes obtaining, by a base station, capability information of user equipment (UE). The first capability information is used to allocate a data scheduling resource for a data transmission of the terminal device, and the data transmission is through a control plane. The base station indicates allocated data scheduling resource to the terminal device. Then, the base station receives, on the data scheduling resource, a radio resource control connection (RRC) establishment complete signaling, where the RRC connection establishment complete signaling includes a non-access stratum (NAS) message, and the NAS message includes data sent by the terminal device.
