Coordination in self-organizing networks

Abstract

To decide, whether or not a SON function instance is allowed to execute, a priority, an impact time and an impact area for the SON function instance is determined, and priorities of other SON function instances scheduled to be run during the impact time of the requesting SON function instance and having an overlapping impact area are compared to the priority of the requesting SON function instance.

Description

technical field [0001] The present invention relates to communication networks, and in particular to ad hoc networks. Background technique [0002] The development of communication technology, especially wireless communication technology, has increased the complexity of the network and the number of network nodes, thereby increasing the operation and maintenance tasks, ie management tasks. To automate at least some tasks, a concept called Self-Organizing Networks (SON) was introduced by the Next Generation Mobile Networks (NGMN) Alliance and 3GPP (Third Generation Partnership Project) to be first used in Long Term Evolution (LTE) access networks, and later used in other networks, both in access and core networks. An ad hoc network is capable of self-configuring and continuously self-optimizing itself in response to network and traffic changes. In such a network, without human involvement, the network and / or network nodes automatically change their configuration parameters,...

Problems solved by technology

One challenge to this coordination is the ability to purchase "plug-and-play" network nodes that support ad-hoc network functionality from any vendor, rather than purchasing single network nodes, CSPs can purchase vendor-specific domains, and / or organize network nodes purchased from different vendors into different vendor-specific domains, each domain covering a geographic area and unaware of the runtime profile of the other domains
