Single call and group call method and device for dual-mode terminal

The invention provides a single call and group call method and device for a dual-mode terminal, and the method comprises the steps: recognizing that a called terminal is a broadband and narrowband dual-mode terminal and the current working mode of the called terminal after a core network of the called terminal receives a call request of a calling terminal; and the core network initiates a call request to a mode number corresponding to the called terminal according to the current working mode of the called terminal. According to the method and the device, the current working mode of the dual-mode terminal can be identified, and the call is initiated to the corresponding mode number according to the current working mode of the dual-mode terminal, so that the problem that the call cannot be established due to the fact that the working mode of the called dual-mode terminal is inconsistent with the called mode is solved, and the call success rate of the dual-mode terminal is improved. 本发明提供了一种双模终端单呼和组呼呼叫方法及装置，该方法包
