Abstract:
A call management method for a multi-subscriber identity module (SIM) multi-active terminal, where multiple user cards register with a centralized call management module of the multi-SIM multi-active terminal. The method includes, when a first user card is used for making a call or receiving a call, determining call statuses of the multiple user cards according to a connection list in the centralized call management module, where the connection list is used to record connection data of the multiple user cards; and when a second user card is in a conversation state, setting the first user card to a waiting state; or setting the first user card to a conversation state, and setting the second user card to a waiting state; or simultaneously setting the first user card and the second user card to a conversation state, to implement a conference call.
