Abstract: A called terminal device camping on a 5th generation (5G) standalone (SA) network receives a paging message. The called terminal device may start a first timer when detecting that a data radio bearer (DRB) for transmitting Internet Protocol (IP) multimedia subsystem (IMS) data is established, and detect whether IMS data is received in an on period of the first timer. If the first timer expires and the called terminal device does not receive INVITE or other IMS data, it is considered that the network is abnormal and therefore the IMS data (such as INVITE) cannot be received. In this case, the called terminal device may actively fall back to long term evolution (LTE) to receive an incoming call. In this way, the called terminal device can receive an INVITE message or a paging message in an IMS domain on the LTE, thereby avoiding a failed incoming call.

Abstract: A call drop rate reduction method includes, when a terminal receives a second identity verification request after an initial identity verification and authentication, the terminal compares the first identity verification request received during the initial identity verification with the second identity verification request. After the second identity verification and authentication fails, the terminal monitors a direction of the call service within the timing duration corresponding to the T3320 timer, and when the call service is redirected to success, the terminal automatically stops the T3320 timer to prevent the terminal from automatically executing the call drop process after the T3320 timer expires, thereby effectively avoiding misjudgment in the identity verification and authentication stage, and addressing a call drop caused by misjudgment in the identity verification and authentication stage in existing user scenarios, which reduces the call drop rate and improves user experience.
