摘　　要：携号转网服务是移动用户变更已签约的电信运营商时仍然持有当前号码的一项服务。区块链技术的本质是分布式数据存储、加密算法、共识机制、点对点传输等技术的集合,具有去中心化、数据溯源及不可篡改等特性。首先介绍了携号转网服务的含义和国内外开展情况,梳理了基于区块链实现携号转网服务在标准研究和行业研究方面的进展,进而提出一种详细的“区块链+携号转网”融合方案,包括功能架构和部署方案,最后分析了该方案在数据同步、监督管理和可扩展性3个方面的优势。The number portability refers to the service of a mobile subscriber to change operators without change mobile number.Blockchain,on the other hand,is an application mode combining distributed data storage,encryption algorithm,consensus mechanism,point-to-point transmission,and other computer technologies,which has the characteristics of decentralization and immutability. It starts from a brief introduction of number portability service as well as its worldwide running status. Also,the progress of related standard and industry research of the service upon blockchain is summarized. Then a detailed integration solution of blockchain and mobile number portability is presented,which includes the functional architecture and deployment scheme. Finally,it lists the main advantages of the solution in the aspects of data synchronization,system monitoring and management,and scalability.
