Registration Signaling Feedback for Information Element Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The registration procedure in communication systems often fails to align information elements between the network side and the terminal side, leading to misalignment and impaired subsequent communication.
Innovation Solution
A communication method involving a terminal sending a registration request message, receiving a registration accept message with first indication information, and sending a registration complete message based on the accept message, ensuring alignment of information elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network side sends a registration accept message without requiring acknowledgment, then the communication procedure is simpler and faster, but the information element alignment between network side and terminal side cannot be ensured
Solution Approach 1:
The patent introduces a feedback mechanism where the terminal sends a registration complete message to acknowledge successful receipt of the registration accept message. This feedback loop ensures that the network side can confirm whether the terminal has correctly received and processed the information elements, thereby ensuring information element alignment while maintaining a relatively simple communication procedure.
2Reliability
If the network side retransmits the registration accept message upon failure to receive acknowledgment, then information element alignment is ensured, but the communication delay increases
Solution Approach 1:
The patent implements a timer mechanism that starts when the network side sends the registration accept message. The timer is configured with a predetermined timeout value. If the registration complete message is not received before the timer expires, the network side retransmits the registration accept message. This preliminary timing arrangement ensures that retransmission only occurs when necessary, minimizing unnecessary delays while ensuring reliability.
3Reliability
If the terminal always sends a registration complete message, then information element alignment is ensured, but the signaling overhead and power consumption increase
Solution Approach 1:
The patent adopts a selective acknowledgment approach where the terminal sends the registration complete message only when it successfully receives and processes the registration accept message containing information elements that require acknowledgment. This partial action approach ensures information element alignment is achieved only when necessary, reducing unnecessary signaling overhead and power consumption compared to always sending acknowledgment.

AI summary
This application provides a communication method and a communication apparatus. The method includes: sending a registration request message; receiving a registration accept message, where the registration accept message carries first indication information, and the first indication information indicates to return a registration complete message after the registration accept message is received; and sending the registration complete message based on the registration accept message. This method helps ensure that an information element in a registration accept message between a network side and a terminal side is aligned, so that the terminal can perform normal communication. In addition, first indication information is carried to enable the terminal to return a registration complete message. This further helps improve system compatibility.
