Description

Technical field

[0001] The present invention relates to a call information processing method and device, in particular to a call information processing method and device based on dual-card dual-standby services in communication technology, and belongs to the field of communication technology. Background technique

[0002] The dual-card dual-standby service means that two subscriber identity module (Subscriber Identity Module, SIM) cards are installed in the same terminal at the same time, and the two SIM cards can work in standby at the same time. In the existing dual-card dual-standby service, the call connection of the dual-cards in the terminal is an independent process, and there is no signaling interaction between each other. When the first SIM card is in a call, the call of the second SIM card can still be made independently, that is, other users can still call through the card number of the second SIM card, and the second SIM card is in the process of connection and the ca...
