Abstract: A method, computer program product and/or computer system assigns access to a quorum disk in a split-storage cluster environment when a communication link between storage systems fails. Access to the quorum disk is based on storage system I/O performance. Priority is given to the storage system that has a higher performance before the link failure. When the communication link fails, both storage systems attempt to access the quorum disk. If the system that first attempts to access the quorum disk is the non-priority storage system, a timer is started. If the priority system attempts to access the quorum disk within a predetermined time interval, the priority system locks the quorum disk and forms the cluster. If the priority system does not attempt to access the quorum disk within the predetermined time interval, the non-priority system locks the quorum disk and forms the cluster.

Abstract: A communication method for a mobile terminal and a mobile terminal, where the communication method includes detecting whether the mobile terminal uses a call service, obtaining a state of an access control circuit when the mobile terminal uses the call service, and selecting a process of network quality monitoring based on the obtained state of the access control circuit, where the process of network quality monitoring includes stopping network quality monitoring, or stopping reporting a network quality monitoring result to a network side. Hence, the network side can process the call service of the mobile terminal based on the process of network quality monitoring performed by the mobile terminal to avoid a before-ringing inter-system handover and improve user experience.
