Title:
COORDINATION EQUIPMENT-BASED CLOUD SERVICE MULTI-CLOUD DEPLOYMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2020/063248
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and provided thereby are a data backup method and device and a communication system. According to the present application, a corresponding standby core network is deployed for each base station; after a terminal is attached by means of the base station, a coordination node synchronizes data of the terminal that are stored in a primary core network element according to a correspondence between the base station and the standby core network. After the terminal is attached, a standby core network element only needs to store the data of the terminal without requiring real-time synchronization with the primary core network element, thereby reducing the operating costs of the standby core network. In addition, each standby core network element only needs to store the data of a terminal that is accessed from a corresponding base station and does not need to store the data of all terminals, which reduces the storage capacity requirements for the standby core network element.
