<p>Methods and systems for implementing call transfer and home network of user terminal are disclosed. One of the methods comprises: the home network of substituted user receiving a first call transfer instruction; the home network of substituted user setting up a second call at the third user terminal to the transfer user terminal based on the first call transfer instruction, and redirecting the call at the transfer user terminal to the substituted user terminal to the third user terminal. Because the transfer user terminal is calling with the substituted user terminal, the transfer user terminal trusts in the substituted user terminal, vice versa. And the home network of the substituted user can get the dialog id in the substituted user terminal side and also get the dialog id in the transfer user terminal side, therefore the call transfer can be implemented successfully.</p> |
