Embodiments of the present invention provide a cluster user-based distributed authentication system, method, and device. The system includes a user data center and at least one network element device, and the user data center is used to receive authentication data sent by an operator, and According to the number segment division information and the service characteristic identification of each of the authentication data, each of the authentication data is sent to the corresponding network element device; the network element device is used to receive the authentication sent by the user data center authorization data, and store the received authentication data; for receiving service data sent by the user, and authenticating the service data according to the stored authentication data corresponding to the user. In the embodiment of the present invention, since the user data center only forwards authentication data, even if a fault occurs, it will not affect the progress of user services, and the network element device performs authentication locally, which not only saves the overhead of the transmission link, but also The transmission delay is greatly reduced and the system reliability is improved.
Description
technical field [0001] The present invention relates to communication technology, in particular to a cluster user-based distributed authentication system, method and device. Background technique [0002] The digital trunking communication system is a communication system mainly characterized by half-duplex two-way group communication. It is a multi-purpose and high-efficiency wireless dispatching communication system in which group users share resources, share costs, and share channel equipment and services. . [0003] In the prior art, the user authentication management function of the data cluster communication system is centrally completed by the home subscriber server (Home Subscriber Server, HSS) in the data cluster communication system, that is, all users in the data cluster communication system send business data Both are sent to the HSS responsible for authentication, and the HSS sends it to the network element device after completing the authentication. [0004] H...
