Managed Object Data Completion via Domain-Network Manager Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-configuration methods in wireless communication networks, such as those in 3GPP EUTRAN, are unable to fully complete the managed object instance for new network elements like eNodeBs, as they cannot generate all necessary configuration parameters, leading to incomplete management and operation by OAM systems.
Innovation Solution
A method and system where a domain manager indicates to a network manager which configuration parameters are needed for a new network element, allowing the network manager to generate and provide these parameters, ensuring all attributes of the managed object instance are populated, including using notifications and operation requests to convey necessary information and data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If self-configuration methods are used for new network elements, then the burden on network operators is reduced and automation is improved, but the managed object instance remains incomplete because not all configuration parameters can be generated automatically
Solution Approach 1:
The patent introduces an intermediary mechanism where the domain manager identifies which configuration parameters can be generated locally and which cannot, then uses a manager system as a mediator to obtain the missing parameters from external sources such as operation and maintenance systems or network management systems, ensuring complete configuration data is assembled.
Solution Approach 2:
The configuration parameter generation process is segmented into two parts: parameters that can be generated automatically by the domain manager (such as default values and locally computable parameters) and parameters that require external sources (such as network-wide configuration data). This segmentation allows the self-configuration process to proceed with available parameters while systematically obtaining the remaining parameters through the intermediary mechanism.
2Loss of information
If all configuration parameters are generated at the domain manager level, then data completion for managed objects is achieved, but the complexity of the domain manager increases and it becomes a bottleneck
Solution Approach 1:
The patent extracts the function of obtaining and managing complete configuration parameter data from the domain manager and places it in a separate manager system. The domain manager retains only the essential self-configuration functions and the ability to identify missing parameters, while the manager system handles the complex tasks of retrieving parameters from external sources and assembling complete configuration data.
3Loss of information
If manual configuration is performed for all parameters, then complete managed object instances are created, but the operating expense and time consumption increase significantly
Solution Approach 1:
The patent implements preliminary action by having the domain manager pre-identify which configuration parameters can be generated automatically and which require external sources, and by having the manager system pre-obtain missing parameters from external sources before the configuration is actually applied. This preliminary preparation eliminates the need for time-consuming manual configuration during deployment.

AI summary
A method of carrying out a self-configuration process in respect of a network element (16) in a cellular wireless network (Figure 1) comprising the steps of : generating first configuration parameters at a domain manager level (14); determining required second configuration parameters which are not to be generated at the domain manager level; notifying a network manager level (12) of the first configuration parameters and the second configuration parameters to cause this level to generate and provide the second configuration parameters and to provide them to the domain manager level; and using the first configuration parameters and the second configuration parameters at the domain manager level to configure the network element.
