关于5G-R MCX漫游用户统一认证的探讨

Discussion on Unifi ed Authentication of 5G-R MCX Roaming Users

5G-RMCX用户漫游到拜访地后,要先经过统一认证IDMS的有效性校验和授权,才能访问拜访地的MCX服务资源。从统一认证IDMS的组网部署、交互认证等角度进行研究和分析,提出全路共用IDMS、全路/路局两级IDMS、路局IDMS等多种组网部署方式,以及对应的交互认证处理机制。

After roaming,a user of 5G-R Mission Critical X-Service(MCX)needs to pass the validity verifi cation and authorization of the Identity Management Server(IDMS)for unifi ed authentication in order to securely access the MCX service resources of the visited place.This paper studies and analyzes IDMS network deployment and interactive authentication,etc.,and proposes a variety of networking methods such as IDMS shared by all railways,two-level IDMS of all railways/railway bureaus,and IDMS deployed by railway bureaus,as well as their corresponding interactive authentication mechanisms.
