A method performed by a virtual subscriber identity module management server for implementing a virtual subscriber identity module of a terminal, comprising: receiving a virtual subscriber identity module, VSIM, application request sent by the terminal, wherein the VSIM application request carries an identifier of a VSIM desired by a user of the terminal; obtaining corresponding VSIM installation information according to the identifier of the desired VSIM; and sending the VSIM installation information to the terminal, to enable the terminal to install the VSIM according to the VSIM installation information; characterized in that after the sending the VSIM installation information to the terminal, the method further comprises: receiving binding request information sent by the terminal, wherein the binding request information carries the identifier of the VSIM of the terminal; obtaining an identifier of an HLR of the VSIM according to the identifier of the VSIM; and according to the identifier of the HLR, sending binding information carrying an identifier of a SIM of the terminal and the identifier of the VSIM to the HLR, to enable, according to the binding information, the HLR correspondingly to store the identifier of the VSIM and the identifier of the SIM, and to establish an association relationship between the identifier of the VSIM and the identifier of the SIM, thus when the mobile switching center receives a paging message carrying the identifier of the SIM, if a query shows that the VSIM bound to the SIM is stored in the HLR, the mobile switching center sends a paging carrying the identifier of the VSIM. receiving a virtual subscriber identity module, VSIM, application request sent by the terminal, wherein the VSIM application request carries an identifier of a VSIM desired by a user of the terminal; obtaining corresponding VSIM installation information according to the identifier of the desired VSIM; and sending the VSIM installation information to the terminal, to enable the terminal to install the VSIM according to the VSIM installation information; characterized in that after the sending the VSIM installation information to the terminal, the method further comprises: receiving binding request information sent by the terminal, wherein the binding request information carries the identifier of the VSIM of the terminal; obtaining an identifier of an HLR of the VSIM according to the identifier of the VSIM; and according to the identifier of the HLR, sending binding information carrying an identifier of a SIM of the terminal and the identifier of the VSIM to the HLR, to enable, according to the binding information, the HLR correspondingly to store the identifier of the VSIM and the identifier of the SIM, and to establish an association relationship between the identifier of the VSIM and the identifier of the SIM, thus when the mobile switching center receives a paging message carrying the identifier of the SIM, if a query shows that the VSIM bound to the SIM is stored in the HLR, the mobile switching center sends a paging carrying the identifier of the VSIM. receiving binding request information sent by the terminal, wherein the binding request information carries the identifier of the VSIM of the terminal; obtaining an identifier of an HLR of the VSIM according to the identifier of the VSIM; and according to the identifier of the HLR, sending binding information carrying an identifier of a SIM of the terminal and the identifier of the VSIM to the HLR, to enable, according to the binding information, the HLR correspondingly to store the identifier of the VSIM and the identifier of the SIM, and to establish an association relationship between the identifier of the VSIM and the identifier of the SIM, thus when the mobile switching center receives a paging message carrying the identifier of the SIM, if a query shows that the VSIM bound to the SIM is stored in the HLR, the mobile switching center sends a paging carrying the identifier of the VSIM.
