M2M Group Management Consistency Check Flag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine-to-machine (M2M) group management systems face high failure rates in group creation and updates due to inconsistencies in member types, leading to reduced flexibility in using M2M technology.
Innovation Solution
A method and apparatus for M2M group management that includes receiving a group creation request, checking consistency between member types and the group type, and setting a consistency check flag, with options to delete inconsistent members or groups, and utilizing consistency policies and notifications for unreachable members to ensure successful group creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the group server checks consistency between member types and group type, then the reliability of group creation is improved, but the flexibility of group creation is worsened due to high failure rate
Solution Approach 1:
The patent applies preliminary action by performing consistency checks before group creation is finalized. The group server checks member type consistency in advance and sets a consistency check flag to indicate whether the check has been performed. This allows the system to identify and resolve type inconsistencies before they cause failures, thereby improving reliability while maintaining flexibility by not blocking group creation outright but rather preparing the system in advance to handle potential issues.
Solution Approach 2:
The patent implements feedback by having the group server return consistency check results to the requesting apparatus through the group creation response. The consistency check flag provides feedback information about whether the consistency check was performed and its outcome. This feedback mechanism allows the requesting apparatus to understand the status of type consistency and take appropriate actions, improving both reliability through validation and flexibility through informed decision-making.
2Reliability
If the group server immediately fails group creation on type inconsistency, then the reliability is maintained, but the ease of operation is worsened due to frequent failures
Solution Approach 1:
The patent applies preliminary action by performing consistency checks before group creation is finalized. The group server checks member type consistency in advance and sets a consistency check flag to indicate whether the check has been performed. This allows the system to identify and resolve type inconsistencies before they cause failures, thereby improving reliability while maintaining flexibility by not blocking group creation outright but rather preparing the system in advance to handle potential issues.
Solution Approach 2:
The patent implements feedback by having the group server return consistency check results to the requesting apparatus through the group creation response. The consistency check flag provides feedback information about whether the consistency check was performed and its outcome. This feedback mechanism allows the requesting apparatus to understand the status of type consistency and take appropriate actions, improving both reliability through validation and flexibility through informed decision-making.
3Measurement precision
If the group server performs consistency check for all members, then the measurement precision of group composition is improved, but the time consumption increases
Solution Approach 1:
The patent applies partial action by checking consistency for members that are reachable and available, rather than attempting to check all members regardless of their status. The group server determines which members are reachable and performs consistency checks only on those members. This partial checking approach reduces the time required for consistency verification while still ensuring accurate measurement of group composition for the members that can be verified, thereby balancing measurement precision with time consumption.
Solution Approach 2:
The patent implements self-service by having the group server automatically determine reachability status of members and decide whether to perform consistency checks based on that status. The system autonomously identifies which members can be checked and which cannot, without requiring external intervention. This self-service mechanism optimizes the balance between measurement precision and time consumption by automatically adapting the checking scope to the actual state of group members.

AI summary
The present invention provides a method and an apparatus for group management during M2M communication, to increase the flexibility of creating and using M2M groups. The method for group management during M2M communication includes: receiving a group creation request carring a group type of a group requested to be created; checking consistency between member types of members in the group and the group type and setting a consistency check flag of the group according to a consistency check result; and returning a group creation response that carries the consistency check result to the requesting apparatus. The creation of the group will not fail because of type check, which greatly increases the flexibility of using the M2M technology.
