XDM Forwarding System Authority and Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for implementing an XML Document Management (XDM) forward function in XDM v2.0 lack efficient mechanisms for forwarding XML documents while ensuring authority checks, minimizing signaling overhead, and securely routing documents between domains.
Innovation Solution
The proposed system and method for XDM forward function include an XDM forward requesting user, an XDMS that checks authority and modifies documents if necessary, and an XDM forward receiving user, with receiver authorization to ensure document ownership and storage, utilizing XCAP URI for indirect recording to reduce signaling overhead and applying filters to forward only parts of documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the entire XML document is forwarded to the receiving user, then the receiving user obtains complete document content, but signaling overhead increases and network resources are consumed
Solution Approach 1:
The patent extracts and forwards only the necessary portions of the XML document rather than the entire document. The forwarding system identifies and transmits only the specific data elements or subsets of the XML document that the receiving user needs, thereby reducing signaling overhead while maintaining document completeness for the required information.
Solution Approach 2:
The XML document is segmented into multiple parts or sections, and only the relevant segments are forwarded to the receiving user. This segmentation allows the system to transmit minimal necessary data while preserving the完整性 of the required information, thus reducing network resource consumption without losing essential document content.
2Reliability
If the XDM system performs comprehensive authority checks and document modifications, then document security and ownership are ensured, but system complexity and processing time increase
Solution Approach 1:
The system performs authority checks and determines document ownership before the actual forwarding operation. By conducting these security validations in advance, the system ensures document security and proper authorization while avoiding repeated complex checks during the forwarding process, thus reducing overall system complexity and processing time.
Solution Approach 2:
The patent introduces an intermediary forwarding system that acts as a mediator between the sending and receiving users. This intermediary handles the complex authority verification, document modification, and ownership confirmation processes, thereby ensuring document security while shielding the end users from the complexity of these operations.
3Loss of energy
If the system forwards modified parts of the XML document, then network resource usage is reduced, but the accuracy and completeness of the forwarded information may be compromised
Solution Approach 1:
The system applies local quality by forwarding different portions or modifications of the XML document based on the specific needs of the receiving user. Rather than uniformly transmitting the entire document or arbitrary segments, the system selectively forwards only the locally relevant parts or modified sections that maintain information completeness for the intended purpose, thus reducing network resource usage without compromising necessary information accuracy.

AI summary
Disclosed are a system and a method for implementing an XDM forward function described in [XDM2_RD] and [XDM2 AD]. The method includes the steps of: transmitting, by the XDM forward requesting user a forward request message for forwarding a desired XML document to the XDMS; receiving, by the XDMS the forward request message, determining if the XDM forward requesting user has been granted a forward authority for a forward-requested target XML document forwarding the requested XML document to the XDM forward receiving user when the XDM forward requesting user has been granted an authority to forward the target XML document, performing receiver authorization for determining if an XDM forward receiving user can accept the forwarded XML document, and confirming that the XDM forward receiving user owns the forwarded XML document and storing the possessed XML document in a user directory when the receiver authorization has been successfully performed.
