The method includes steps: (1) through HRPD network, MSC of cdma2000 network sends the calling number in this voice seeking to terminal in active state resided in HRPD network; (2) based on received calling number, the terminal determines whether to receive this voice seeking; if yes, executing step (3); otherwise, through HRPD network, sending message of refusing this voice seeking to MSC, and ending; (3) the terminal switches to cdma2000 network, cdma2000 network assigns service channel; through cdma2000 network, the terminal receives this voice seeking. If user terminal does not want to receive this voice seeking, the invention can prevent switching between high-speed packet data service network and cdma network. |
