Abstract: A communication method comprises that if a policy control device does not support setup of an Internet Protocol (IP) multimedia subsystem (IMS) default bearer during setup of an IMS default bearer for a terminal, the control plane gateway sends second indication information to a user plane gateway, where the second indication information indicates the control plane gateway bypasses the policy control device. When the user plane gateway receives an IMS session request from the terminal and determines that the control plane gateway bypasses the policy control device, the user plane gateway sends first indication information to the control plane gateway, and the first indication information indicates the control plane gateway to send, to the policy control device, a first request to request to establish a mapping relationship between the terminal and the control plane gateway such that an IMS session can be set up between terminals.

Abstract: A heartbeat-based data synchronization method is disclosed. The method is applied to a distributed storage system, and at least one data block group is stored in the distributed storage system. The distributed storage system includes multiple storage devices, one device in the multiple storage devices is a primary device for storing the data block group, and other devices are secondary devices for storing the data block group. The primary device performs the method. The primary device obtains access status information of the data block group, determines a heartbeat time of the data block group according to the access status information of the data block group, and sends a data synchronization instruction to the secondary device according to the heartbeat time of the data block group, where the data synchronization instruction is used to instruct the secondary device to synchronize data.
