Wireless Resource Attribute Classification for M2M Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, existing methods for managing access to resources in M2M environments are inefficient, particularly in announcing and de-announcing attributes of resources, which leads to unnecessary information overhead and resource discovery challenges.
Innovation Solution
A method is introduced to classify resource attributes into mandatory (MA), optional (OA), and not announced (NA) types, allowing for selective announcement and de-announcement of attributes, and the use of an 'announcedAttribute' list to manage attribute updates and creations, optimizing resource management and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all attributes of an original resource are announced to another entity, then the information completeness is improved, but the information overhead increases
Solution Approach 1:
The patent segments attributes into three distinct types (MA, OA, NA) based on their announcement requirements. This classification allows the system to selectively announce only necessary attributes rather than all attributes, thereby reducing information overhead while maintaining essential information completeness.
Solution Approach 2:
Different attributes are assigned different announcement qualities (mandatory, optional, or not announced) based on their specific requirements. This local differentiation enables optimized information transmission where each attribute receives the appropriate level of announcement treatment, balancing information completeness with overhead reduction.
2Quantity of substance
If selective attribute announcement is implemented, then the information overhead is reduced, but the resource discovery complexity increases
Solution Approach 1:
The system performs preliminary classification of attributes into MA, OA, and NA types before the resource discovery process. This advance preparation establishes a clear framework for attribute announcement, simplifying the resource discovery process despite the selective announcement mechanism by providing pre-organized information structures.
Solution Approach 2:
The patent introduces an intermediary classification mechanism (the three-type attribute classification system) that mediates between the original resource and the announcing entity. This intermediary structure simplifies the discovery process by providing a standardized interface for selective attribute announcement, reducing the complexity burden on the discovery mechanism.
3Reliability
If mandatory attributes are always announced, then the reliability of resource information is improved, but the flexibility in resource management deteriorates
Solution Approach 1:
The patent introduces dynamic attribute management where attributes can transition between different announcement states (MA, OA, NA) based on resource lifecycle events. This dynamic classification allows the system to maintain reliability for critical attributes while providing flexibility to adjust announcement behavior as resources are created, updated, or deleted.
Solution Approach 2:
The system changes the announcement parameter (MA/OA/NA classification) of attributes based on resource operations and requirements. This parameter change mechanism enables the system to adapt attribute announcement behavior dynamically, maintaining reliability when needed while providing flexibility for different resource management scenarios.

AI summary
Disclosed is a method for notifying an attribute of an original resource of one entity to another entity in a wireless communication system according to one embodiment of the present invention. The method may comprise the steps of: receiving an update request for an ‘announcedAttribute’ attribute comprising a list of pre-notified attributes included in the original resource, for notifying a specific attribute of the original resource, wherein each attribute in the original resource is set to one of a mandatory announced (MA) type that should be notified mandatorily, an optional announced (OA) type that is optionally notified according to the contents of the specific attribute in the original resource, and a not announced (NA) type that is not notified; determining whether the specific attribute is the OA type; and notifying the specific attribute to all notified resources of the original resource if the specific attribute is the OA type.
