    Abstract: The present invention provides a wireless communication method and a device. The method is applied to a communications system. The communications system includes user equipment UE, a radio access network RAN, a first core network entity, and at least one network slice. The method includes: establishing, by the first core network entity, a signaling connection to the UE; receiving, by the first core network entity, network slice information and a non-access stratum NAS message that are sent by the UE over the signaling connection; determining, by the first core network entity, a target network slice from the at least one network slice based on the network slice information, where the target network slice includes a second core network entity, and the UE performs NAS communication with the second core network entity by using the RAN and the first core network entity; and sending, by the first core network entity, the NAS message to the second core network entity. In this way, an amount of signaling in a communication process can be reduced, and network management and maintenance efficiency can be improved.

    Abstract: Arrangements for transmitting a release notification message are provided. A second computer receives an error indication message from a first computer, the error indication message including a destination identifier and an address associated with the first computer. A determination is made, whether, in response to receiving the error indication message, a first release notification message was transmitted to a control module in the second computer, the control module being configured to release a bearer connection associated with the destination identifier. If it is determined that the first release notification message has been transmitted to the control module, the transmission of subsequent release notification messages to the control module is stopped if subsequent received error indication messages include the destination identifier and the address.

    Abstract: This application discloses a data transmission method and a first device, to reduce impact of a network packet loss on network transmission efficiency and improve network transmission reliability. The method in this application includes: encapsulating, by a first device, first target data into N RDMA packets according to a remote direct memory access RDMA protocol; sequentially sending, by the first device, the N RDMA packets to the second device according to a PSN sequence of the N RDMA packets, where each of the N RDMA packets carries a first data write address, and the first data write address is an address for writing data in each of the N RDMA packets into the second device, so that the second device directly obtains the first data write address in each RDMA packet from the RDMA packet, and writes the target data into storage space corresponding to the first data write address.
