A method for call transfer comprises: detecting whether a multi-line dialing operation is initiated; if the initiation of a multi-line dialing operation is detected, using multiple lines for initiating call service request to a called terminal. Another method for call transfer is disclosed, the method comprising: after detecting call service requests of different lines from the same calling terminal, connecting respectively each line of the calling terminal, setting one of the lines as the main line, and other lines as the backup lines; after establishing multiple lines between the terminal and the calling terminal, if detecting the call service on the main line is abnormal, switching onto a backup line and continuing the call. The above technical solution can ensure that the call service of mobile terminal supporting dual-(multi-) card can not be intermitted. |
