Content Disposition System for Message Schema Negotiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication networks, especially those using IP Multimedia Subsystem (IMS) networks, interoperability issues arise due to incompatibility of Markup languages and meta-structures across different entities, leading to unpredictable behavior and communication failures when message bodies in extensible Markup languages are not compatible.
Innovation Solution
A content disposition system and method that negotiates schema and document version information for message bodies in communication protocols, allowing entities to identify and process message bodies with indicators for alternative treatments, ensuring compatibility and proper processing across different versions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different entities use different Markup language versions and meta-structures in message bodies, then each entity can use its own preferred version, but interoperability issues arise leading to communication failures
Solution Approach 1:
The patent introduces a schema negotiation mechanism that acts as an intermediary between sender and recipient entities. The sender includes schema information in the message header, and the recipient validates this schema before processing the message body. This intermediary validation layer ensures that even when different Markup language versions are used, compatibility is maintained through systematic schema verification, preventing communication failures while preserving version flexibility.
Solution Approach 2:
The patent implements preliminary schema validation before message body processing. The recipient entity checks the schema information included in the message header prior to attempting to process the message body content. This preliminary action ensures that incompatible message formats are identified and handled appropriately before they can cause communication failures, thereby maintaining reliability while allowing version diversity.
2Reliability
If schema validation is performed on all message bodies, then interoperability is ensured, but processing time and system complexity increase
Solution Approach 1:
The patent applies schema validation selectively rather than uniformly to all messages. The validation mechanism checks schema information only when it is present in the message header, and only validates message bodies that contain indicators requiring alternative treatment. This localized application of validation reduces unnecessary processing complexity while maintaining interoperability assurance for messages that require it.
Solution Approach 2:
The patent changes the parameter of validation scope based on message characteristics. By examining indicators in the message body and schema information in the header, the system dynamically adjusts whether full validation is performed. This parameter-based approach allows the system to maintain high interoperability for complex messages while reducing processing overhead for simpler messages, thereby managing system complexity effectively.
3Ease of operation
If default treatment is applied to message bodies without checking indicators, then processing is simpler, but interoperability issues may occur
Solution Approach 1:
The patent implements a tiered processing approach where default treatment is applied to messages without indicators, but additional schema validation and alternative treatment are applied to messages that contain indicators. This partial action strategy maintains processing simplicity for the majority of messages while ensuring reliability for those requiring special handling, achieving a balance between ease of operation and message processing reliability.

AI summary
In one embodiment, a scheme is disclosed for interpreting contents of at least one message body per message, e.g., a SIP or HTTP message, wherein the message body contents correspond to a content type. A communication protocol message such as a SIP or HTTP message is generated by a sender towards a recipient, wherein the message includes at least one message body content in the message's body. A component associated with the recipient is configured to examine whether at least one indicator is associated with the message. A component, operable responsive to the examination, is configured to inhibit a treatment of the message body content and to apply an alternative treatment with respect thereto.
