Problems solved by technology
However, in the existing 3GPP standard, when the terminal uses VPDN (Virtual Private Dialup Network, virtual private dialup network) to access the 5G network, the terminal selects the corresponding RSD (Route Selection Descriptor, routing selection descriptor) according to the routing selection policy URSP When slicing the network in the network and establishing a corresponding PDU (Protocol Data Unit, protocol data unit) session, the terminal cannot obtain and inform the network of the corresponding VPDN user name and password, resulting in the network being unable to verify the VPDN user name and password, and thus unable to provide VPDN-specific network slices Serve

The invention relates to the technical field of communication, in particular to a network access method and device, terminal equipment, network equipment and a storage medium. The method comprises the following steps: in response to a trigger operation, initiating a target network connection request based on a target network protocol; the target network connection request comprises a preset network traffic descriptor TD corresponding to the target network, and a user name and a password corresponding to the target network; the preset TD is used for identifying and initiating connection to a target network; executing terminal routing selection strategy URSI matching, and determining a matched URSI rule and a corresponding target network slice according to a preset TD; sending a session establishment request to a network side based on the matched URSP rule, and sending the session establishment request to the network side by using a non-access stratum (NAS) message carrying the user name and the password of the target network; the connection of the target network is established in the target network slice when the network side successfully verifies the user name and the password. According to the scheme of the invention, the access of the VPDN service on the specific network slice can be realized.
Description
technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a network access method, a network access device, a terminal device, a network device, and a storage medium. Background technique [0002] In the existing 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) standard, 3GPP R15 / R16 / R17 introduced a terminal routing policy URSP (UE Route Selection Policy) and network slicing. The terminal URSP policy defines the service configuration and routing policy based on APP ID / DNN (DataNetwork Name, data network name) / FQDN (Fully Qualified Domain Name, service fully qualified domain name) / IP traffic descriptor TD (trafficdescriptor). According to the URSP policy, the terminal can realize that the operator provides on-demand network slicing resources for different services, thereby realizing end-to-end network slicing. However, in the existing 3GPP standard, when a terminal uses a VPDN (Virtua...
