Communication method for implementing dual card, dual standby and dual pass connections in a terminal

A terminal supporting dual-receive single-transmit dual-card dual-standby single-pass includes a first subscriber identity module (SIM) card interface and a second SIM card interface. The first SIM card interface is configured to communicate with a first SIM card, and the second SIM card interface is configured to communicate with a second SIM card. When the terminal is in a first communications connection, the terminal receives a paging request for setting up a second communications connection. When the terminal receives the paging request for the second communications connection, if the terminal has a to-be-sent voice packet of the first communications connection, the terminal delays responding to the paging request for setting up the second communications connection, or if the terminal has no to-be-sent voice packet of the first communications connection, the terminal responds to the paging request for setting up the second communications connection.
