A call transfer method for transferring a call from a first mobile terminal, also referred to as first terminal, to a second mobile terminal when a user of the first mobile terminal cannot answer the call because the user is unavailable or busy, wherein the method comprises: sending, by the first mobile terminal, a local number query request to the second mobile terminal by using a near field communication link between the first terminal and the second mobile terminal, wherein the local number query request is used to request the second mobile terminal to query a local number of the second mobile terminal; receiving, by the first terminal, the local number of the second mobile terminal that is sent by the second mobile terminal; and sending, by the first terminal, a call transfer request, for performing a call transfer of the call from the first mobile terminal to the second mobile terminal, to a network side according to the received local number of the second mobile terminal, wherein the call transfer request is used to request the network side to update a call transfer target of the first terminal to the local number of the second mobile terminal; wherein after the sending, by the first terminal, a call transfer request to a network side, further comprising: detecting, by the first terminal according to a preset period, whether the near field communication link established between the first terminal and the second mobile terminal is valid, wherein the near field communication link is valid if it can be used to transmit data; and when the near field communication link established between the first terminal and the second mobile terminal is invalid, sending, by the first terminal, a call transfer request to the network side, wherein the call transfer request is used to request the network side to update the call transfer target of the first terminal to a preset local number, wherein the preset local number is a local number for call transfer that is initially set by the user. sending, by the first mobile terminal, a local number query request to the second mobile terminal by using a near field communication link between the first terminal and the second mobile terminal, wherein the local number query request is used to request the second mobile terminal to query a local number of the second mobile terminal; receiving, by the first terminal, the local number of the second mobile terminal that is sent by the second mobile terminal; and sending, by the first terminal, a call transfer request, for performing a call transfer of the call from the first mobile terminal to the second mobile terminal, to a network side according to the received local number of the second mobile terminal, wherein the call transfer request is used to request the network side to update a call transfer target of the first terminal to the local number of the second mobile terminal; wherein after the sending, by the first terminal, a call transfer request to a network side, further comprising: detecting, by the first terminal according to a preset period, whether the near field communication link established between the first terminal and the second mobile terminal is valid, wherein the near field communication link is valid if it can be used to transmit data; and when the near field communication link established between the first terminal and the second mobile terminal is invalid, sending, by the first terminal, a call transfer request to the network side, wherein the call transfer request is used to request the network side to update the call transfer target of the first terminal to a preset local number, wherein the preset local number is a local number for call transfer that is initially set by the user.
