Abstract: A method for detecting a borehole caving based on cuttings and elements logging data includes: integrating real-time elements logging data and real-time cuttings return data of a target well, and historical elements logging data and stratum evaluation data of an adjacent well; calculating a root mean square deviation (RMSD) ? of a relative content of each element of the target well and the adjacent well and a real-time cuttings return ratio; setting a threshold ? of the RMSD ? of the relative content of each element and a threshold range (a,b) of the real-time cuttings return ratio; and establishing an intelligent stratum identification model based on a support vector machine (SVM) for real-time determination of a horizon from which current cuttings are returned. The method can achieve effective borehole caving detection, such that on-site personnel can deal with borehole caving in time and prevent it from developing into a complicated drilling accident.

Abstract: This application discloses a link fault handling method, a related apparatus, a storage medium, and a program product, and belongs to the field of communication technologies. In this method, a forwarding plane component of a network device updates a reference state table in time by actively polling a port status register, so that when forwarding a data flow, the forwarding plane component can sense a local faulty link in time based on the reference state table, and perform link switching in time, and a PHY chip does not need to report fault information to a control plane CPU in the network device, or wait for the control plane CPU to deliver an instruction. That is, this solution does not depend on control plane path computation, and does not require additional communication from a data plane to a control plane, to avoid a delay caused by fault handling of the CPU.

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.
