Embodiment Construction
[0056] In the present invention, when the multi-mode terminal accesses the first network and needs to use the second network, the first network receives the second network login request of the multi-mode terminal, and the second network login request carries the multi-mode terminal in the second network login request. The identifier in the second network—the second identifier; the first network verifies whether the multimode terminal initiates the second network login request according to the second identifier, and the first network notifies the second network that the multimode terminal has indeed initiated the second network login request, and the second The network verifies the validity of the resource access token acquired by the multi-mode terminal, and the second network can provide the resource access token to the multi-mode terminal through the first network; the second network determines the resource access token of the multi-mode terminal After valid, multi-mode termi...
