PROCESSING METHOD FOR TERMINAL ACCESS TO 3GPP NETWORK AND DEVICE Russian patent published in 2019 - IPC H04W48/02 

FIELD: data processing.

SUBSTANCE: invention relates to processing for terminal access to a 3GPP network. UE sends an access request message to the core network device in a 3GPP network, and the primary network device sends an unauthorized access message to the UE after determining that the UE does not have permission to access the 3GPP network. Unauthorized access message includes authentication information of the underlying network device. UE performs authentication on the main network device in accordance with the authentication information of the main network device and implements the corresponding network access policy after successfully completing the authentication on the main network device by UE, that is, after UE determines that the source of the unauthorized access message is authorized to reduce the number of access request messages that are sent to the basic network device.

EFFECT: reducing the load on the main network device.
