Method for maintaining function when connection to back end is interfered in communication system

A first general aspect of the present disclosure relates to a computer-implemented method for maintaining a function in a local instance in the event of connection interference to a backend in a communication system having the backend and a plurality of local instances, wherein the backend provides backend information for the function; the method includes receiving, by the backend, a local behavioral model from a plurality of local instances, where the local behavioral model provides the functionality in the local instances when particular backend information is unavailable; creating a behavioral model based on the received local behavioral model; and transmitting, by the backend, the behavioral model to a local instance of the plurality of local instances. 本公开的第一一般方面涉及一种用于在具有后端和多个本地实例的通信系统中至后端的连接干扰的情况下维持本地实例中功能的计算机实现的方法，其中所述后端为所述功能提供后端信息；该方法包括由所述后端从多个本地实例接收本地行为模型，其中当特定的后端信息不可用时，所述本地行为模型在所述本地实例中提供所述功能；基于接收到的本地行为模型创建行为模型；以及由所述后端将所述行为模型传送到所述多个本地实例中的本地实例。
