The northbound data of the mobile communication network management system is an important performance indicator in mobile communication, which is of great significance for guiding network planning, construction, operation and maintenance. Since the northbound data comes from different units, data may be tampered with during the process of data collection, storage and usage. In order to solve the problem of data tampering and implement a credible data management method, in this paper, we will combine blockchain technology to propose a dual-chain storage structure, which stores core data and data operation logs on the chain, so as to realize the management and operation of data and ensure data security and credibility.
