  • Patent number: 12288168
    Abstract: A blockchain-based room inventory management system includes a property management system (PMS) module and an intermediate server system. The PMS module may be under a hotel's direct control. The intermediate server system communicates with at least one online travel agency (OTA) module and/or at least one booking engine using Ethereum-based smart contracts for confirming and processing a room reservation event. If the room reservation event is confirmed to be a successful transaction, the intermediate server system also updates the successful transaction into the PMS module and a blockchain formed by multiple node servers. The blockchain contains multiple blocks arranged in a chronological order for distinguishing successful transactions of different moments. In this way, each successful transaction is prevented from wrongly preceded by a later successful transaction. And the room inventory management system neutralizes an overbooking issue accordingly.

  • Publication number: 20250104703
    Abstract: An apparatus may comprise a memory communicatively coupled to a processor. The processor may be configured to receive a request to perform multiple data processing operations and determine multiple sub-dialogues corresponding to the request. The sub-dialogues are part of a plurality of IVR operations. The processor may be further configured to route the request to a microservice of the microservices based at least in part upon the sub-dialogues. The microservice may be configured to fulfill the request. The processor may generate a response to the request associated with the microservice, update publishing commands in accordance with one or more rules and policies in response to generating the response, and publish the first microservice. The publishing commands associated with the microservice may be updated in isolation from the rest of the microservices.
