TLV Fields in Control Messages for Short User Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently transmitting short messages using control messages, particularly in idle modes and across different network configurations, which affects data transfer speed and user message delivery.
Innovation Solution
The solution involves using a Type Length Value (TLV) field within control messages like RNG-REQ and RNG-RSP to carry short messages, allowing for their transmission even in idle modes and varying network setups, by defining specific types and subtypes for SMS, and employing L2 transfer mechanisms to negotiate bandwidth and confirm message delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate SMS and MMS systems are used with different messages, then text and multimedia messaging are supported, but system complexity increases and data transfer efficiency decreases
Solution Approach 1:
The patent combines SMS and MMS messaging capabilities into a unified message structure that can carry both text and binary data. Instead of maintaining separate SMS and MMS systems with different protocols, the invention uses a single message framework that adapts to carry different types of content, thereby reducing system complexity while maintaining versatility.
Solution Approach 2:
The patent creates a universal message structure that can serve multiple functions - carrying text messages, multimedia content, and control information all through the same protocol. This multi-functional approach eliminates the need for separate specialized systems, reducing overall system complexity while maintaining adaptability across different messaging needs.
2Productivity
If control messages are used to carry short messages, then message transmission efficiency improves, but message delivery reliability may be affected due to control message prioritization
Solution Approach 1:
The patent segments the control message into distinct functional parts, with specific fields designated for user messages. By separating the control functionality from the user message content within the same message structure, the system can efficiently transmit messages while ensuring that critical control operations are not compromised by user message traffic.
Solution Approach 2:
The patent introduces a message structure that acts as an intermediary between control plane and user plane communications. This structured format allows user messages to be carried within control messages while maintaining proper prioritization and delivery guarantees, effectively mediating between efficiency and reliability requirements.
3Productivity
If TLV fields in control messages are used for short message transmission, then bandwidth utilization improves, but message format complexity increases
Solution Approach 1:
The patent utilizes the flexible TLV (Type-Length-Value) parameter structure to dynamically adapt message formats based on content requirements. By leveraging the inherent flexibility of parameter-based encoding, the system achieves efficient bandwidth utilization while managing format complexity through standardized parameter definitions and interpretation rules.

AI summary
Short user messages can be conveyed in system management signaling for a data or telephony network. In one example, a first control message is sent from a first radio to a second radio, the control message including a data field, the data field containing a short message directed from a user of the first radio to a user of a third radio. In response, a second control message is received in reply to the first control message from the second radio, the second control message including a data field, the data field containing a response to the short message.
