A calling method for a video phone, comprising: the steps of establishing a third bearer of video phone between a calling terminal and a Multimedia Ring Back Tone server; playing a Multimedia Ring Back Tone to the calling terminal via the third bearer; and establishing a fourth bearer of video phone between the calling terminal and a called terminal, and performing a video phone communication between the calling terminal and the called terminal via the fourth bearer; the third bearer and the fourth bearer are video phone communication links established through a video phone signaling protocol process, the video phone signaling protocol is H.324 or H.323; wherein before establishing the fourth bearer of video phone, the method further comprises: removing the third bearer established between the calling terminal and the Multimedia Ring Back Tone server upon detecting that the called terminal answers the call; the method further characterised by the steps of: receiving, by the calling terminal, a first message from a Mobile Switching Center server before detecting that the called terminal answers the call, and indicating to the calling terminal that charging has not started yet, wherein the first message is used to indicate to the calling terminal to ignore timing or charging the video phone call; and receiving, by the calling terminal, a second message from the Mobile Switching Center server when detecting that the called terminal answers the call, and indicating to the calling terminal that timing or charging has started, wherein the second message is used to indicate to the calling terminal to initiate timing or charging the video phone call. the steps of establishing a third bearer of video phone between a calling terminal and a Multimedia Ring Back Tone server; playing a Multimedia Ring Back Tone to the calling terminal via the third bearer; and establishing a fourth bearer of video phone between the calling terminal and a called terminal, and performing a video phone communication between the calling terminal and the called terminal via the fourth bearer; the third bearer and the fourth bearer are video phone communication links established through a video phone signaling protocol process, the video phone signaling protocol is H.324 or H.323; wherein before establishing the fourth bearer of video phone, the method further comprises: removing the third bearer established between the calling terminal and the Multimedia Ring Back Tone server upon detecting that the called terminal answers the call; the method further characterised by the steps of: receiving, by the calling terminal, a first message from a Mobile Switching Center server before detecting that the called terminal answers the call, and indicating to the calling terminal that charging has not started yet, wherein the first message is used to indicate to the calling terminal to ignore timing or charging the video phone call; and receiving, by the calling terminal, a second message from the Mobile Switching Center server when detecting that the called terminal answers the call, and indicating to the calling terminal that timing or charging has started, wherein the second message is used to indicate to the calling terminal to initiate timing or charging the video phone call. receiving, by the calling terminal, a first message from a Mobile Switching Center server before detecting that the called terminal answers the call, and indicating to the calling terminal that charging has not started yet, wherein the first message is used to indicate to the calling terminal to ignore timing or charging the video phone call; and receiving, by the calling terminal, a second message from the Mobile Switching Center server when detecting that the called terminal answers the call, and indicating to the calling terminal that timing or charging has started, wherein the second message is used to indicate to the calling terminal to initiate timing or charging the video phone call.
