Abstract:
A call hold method includes receiving a call hold request sent from a peer end; returning a 200 OK message to the peer end; receiving a user instruction for sending a call hold request to the peer end; determining whether an acknowledgement message based on the call hold request of the peer end is received from the peer end; and processing, based on an acknowledgement message determining result, the user instruction for sending a call hold request to the peer end. Accordingly, when a user has a call hold request, a mobile terminal first determines whether a procedure based on the call hold request of the peer end is completed at the peer end, and then determines to process the call hold request of the user, thereby preventing a call drop.
