Multi-network manager, method and system

摘要

A method for reducing interference between wireless networks for industrial devices. The method includes the steps of: obtaining a first resource schedule of a first wireless network manager; obtaining a second resource schedule of a second wireless network manager; determining whether there are resource conflicts between the first resource schedule and the second resource schedule; and providing, when at least one resource conflict is determined, a new wireless resource schedule for the first wireless network manager to avoid at least part of the determined resource conflicts. A corresponding multi-network manager, system and computer program product are also presented.

1. A method for reducing interference between at least two wireless networks for industrial devices, comprising the steps of:
providing a centralized architecture comprising a multi-network manager that is configured to establish resource allocations and assignments in at least one of the at least two wireless networks; obtaining by the multi-network manager a first resource schedule of a first wireless network from a first manager of the first wireless network; obtaining by the multi-network manager a second resource schedule of a second wireless network from a second manager of the second wireless network; determining by the multi-network manager whether there are resource conflicts between said first resource schedule from said first manager and said second resource schedule from said second manager; and generating via the multi-network manager, when at least one resource conflict is determined, a new wireless resource schedule which assigns resources to industrial devices in the first wireless network, and transmitting said new wireless resource schedule to said first manager of the first wireless network, wherein said first manager implements the new wireless resource schedule into the first wireless network to avoid at least part of said determined resource conflicts; wherein said first and second resource schedules and said new wireless resource schedule are time slot schedules or frequency hopping information for channels of the respective wireless network or a combination of both.
