摘要： A method for devices without SIM card (SD) to communicate directly with a core network. The method may be performed in the following matter. The SD registers with the core network through a cellular device (MD) in order to obtain a credential for the SD. The credential comprises Access ID, key, and control parameters. The SD then performs a mutual authentication directly with the core network using the credential. If the SD authenticates successfully with the core network, the SD is granted access to the servers via the core network.

摘要： A data transmission method, a related device, and a related system. The method includes: receiving, by a first access network device, a data packet (for example, small data) sent by user equipment (for example, an IoT device), where the data packet includes a first cookie and raw data; verifying, by the first access network device, the first cookie, to obtain a verification result; and processing, by the first access network device, the raw data based on the verification result. Implementation of embodiments can reduce load on a network side when a large quantity of user equipments need to perform communication, thereby increasing data transmission efficiency.

摘要： A key management method/apparatus (user equipment) are described. The key management includes encrypting user identity information based on a first public key. The user equipment sends a first user identity message to a first network device. The first user identity message includes the user identity information, an indication identifier that indicates whether the user identity information is encrypted, and a reference identifier for indexing the first public key. The first network device sends, to a second network device, a third user identity message including the user identity information and the reference identifier that indexes the first public key. Thus, when receiving the third user identity message, the second network device can determine the encrypted user identity information, according to a pre-stored mapping table including the first private key.
