Claim of US Patent No. 9,444,803

1. An authentication method oriented to a heterogeneous network, comprising steps of:
after receiving a service request sent by a virtual terminal, generating, by a unified authentication server located at a
core network layer, a service token according to the service request, and sending the service token to the virtual terminal
and a target network;

submitting, by the virtual terminal, the service token to the target network, and
requesting the target network to provide service data; and
comparing, by the target network, the service token submitted by the virtual terminal with the service token sent to the target
network by the unified authentication server, and providing the service data to the virtual terminal when the service token
submitted by the virtual terminal is consistent with the service token sent to the target network by the unified authentication
server,

wherein the method further comprises steps of: after receiving the service request sent by the virtual terminal,
authenticating, by the unified authentication server, whether a target network is capable of providing service data required
by a member terminal device in the virtual terminal according to a list of radio resources accessed by the member terminal
device in the service request; and determining, according to an identifier of the virtual terminal and an identifier of the
member terminal device in the virtual terminal in the service request, whether the virtual terminal and the member terminal
device is authorized to download service data from the target network; and

when the target network is capable of providing the service data required by the member terminal device and the virtual terminal
and the member terminal device is authorized to download the service data from the target network, generating, by the unified
authentication server, the service token.
