The application provides a scalable multi-channel fallback method for 5G messages, comprising the following steps: step one: configuring 5G messages, and sending the 5G messages to an operator; step two: based on step one, realizing the fallback of the 5G messages through a multi-channel fallback mechanism after the messages are sent; step three: based on step two, establishing a scalable framework; step four: based on step three, establishing a flexibly configurable sending strategy; step five: based on step four, establishing a fallback failure compensation sending mechanism; and step six: based on step five, 5G message fallback reading. Through the configuration between various processes, the application quickly realizes the fallback of 5G messages, improves the delivery rate of the messages, realizes the accurate fallback of business scenarios, improves the delivery effect, improves the business conversion rate, and saves costs.
