Abstract: A state-aware microservice system for managing messages and providing a service. The state-aware microservice system includes a plurality of instances of the service, a message broker, a memory, and an electronic processor. The processor is configured to receive, via an instance of the plurality, a message for the service and determine whether a processing of the message is consistent with a current state of the system. When the processing of the message is consistent, the processor process the message via one of the plurality of instances. When the processing of the message is not consistent, the processor transmits the message to a first queue of the message broker, determines, from a timer of the message, a time-to-live of the message, and transfers the message to a second queue of one of the plurality of instances in response to the time-to-live expiring.

Abstract: A method and apparatus is disclosed for dynamically switching an operating address book upon registering a migrating radio with a visited network. Prior to migrating, the radio uses a first address book in a home network to identify calling radios in the home network, wherein the first address book includes information associated with radios in the home network. Upon roaming to a visited network, the radio registers with the visited network and the radio retrieves an additional network specific address book for the visited network. The radio automatically switches to the additional network specific address book, upon registering with the visited network. Subsequent calls received by the radio are thereafter identified according to information stored in the additional network specific address book.
