Wireless Message Transmission with Non-Encoded Security Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless telecommunications, the establishment of encrypted connections is delayed due to the need for explicit security mode commands and subsequent ciphering reconfigurations, especially when a mobile device moves between network nodes, leading to additional signaling messages and complications.
Innovation Solution
The method involves transmitting a message with a non-encoded portion containing decoding information for an encoded portion, allowing for simultaneous transmission and reception of encoded messages, thereby combining the Security Mode Command with subsequent RRC or NAS signaling messages to expedite the encryption process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If explicit security mode commands are used to establish encrypted connections, then security is ensured, but connection establishment delay increases
Solution Approach 1:
The patent combines the security mode command with subsequent RRC or NAS signaling messages into a single transmitted message. The message contains both unencoded security parameters and encoded data, allowing the receiver to simultaneously obtain security configuration and application data without requiring separate transmission steps, thereby reducing connection establishment delay while maintaining security
Solution Approach 2:
The patent includes unencoded security parameters at the beginning of the message before the encoded data. This preliminary placement of decoding information allows the receiver to prepare the decryption function in advance using the unencoded security parameters, enabling immediate decryption of the subsequent encoded portion without waiting for separate security configuration steps
2Measurement precision
If separate security mode command and ciphered messages are transmitted, then decryption accuracy is ensured, but signaling complexity increases
Solution Approach 1:
The patent merges the security mode command and ciphered messages into a single composite message structure. This unified message contains both unencoded security parameters and encoded data, reducing the number of separate signaling exchanges while maintaining the ability to accurately decrypt through the integrated security information
Solution Approach 2:
The message is segmented into distinct unencoded and encoded portions, with clear demarcation between security parameters and application data. This segmentation allows the receiver to process each portion appropriately - using the unencoded security parameters to configure the decryption function, then applying it to the encoded portion - thereby maintaining decryption accuracy while simplifying the overall signaling process

AI summary
A method is provided for controlling encoded transmissions in a wireless system. On the transmitting end of the system, the method comprises transmitting a message having a first non-encoded portion and a second encoded portion. The first non-encoded portion has information contained therein regarding decoding the second encoded portion. On the receiving end of the system, the method comprises receiving a first message and determining if a portion of the first message contains unencoded information. The unencoded information is used to decode an encoded portion of the first message.
