Abstract:This paper studies the problem that the notifications cannot be delivered to the active domain in the target MPS Mobile Police special multi-mode terminal from another isolated domain, and puts forward a feasible concept or scheme named “Domain Crossovers Notification Service for Mobile Police” as a solution to it. Furtherly, based on combination of multiple technologies such as MQTT, AMQP, RESTful, MVC, a more reasonable system implementation including notification pushing feature, cross domain synchronization mechanism, general message exchange component, notification service interface, archives management, content inspector and filter, priority-based hint strategy, etc., is proposed. With it, the infrastructure of mobile police service platform can evolve onto a more perfect, advanced, effective, efficient, secure, compliant new level.
