Paging Method Reducing Signaling Overhead via Identifier Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In New Radio (NR) systems, the high demand for signaling overhead in the paging process poses a challenge that existing technologies have not adequately addressed, leading to inefficiencies in communication.
Innovation Solution
The proposed solution involves determining a paging time using at least one bit of a terminal device's identifier and transmitting a paging message that carries identifier information based on additional bits or a shorter identifier, reducing the overall signaling overhead by using fewer bits for the identifier information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the full identifier of the terminal device is carried in the paging message, then the terminal device can accurately identify itself, but the signaling overhead increases
Solution Approach 1:
The identifier is segmented into two parts: the first N bits are used to determine the paging time, and the remaining bits (second identifier) are used to identify the terminal device in the paging message. This segmentation allows the system to use only the necessary portion of the identifier in the paging message, reducing signaling overhead while maintaining identification accuracy.
Solution Approach 2:
The patent extracts only the necessary portion of the identifier (the second identifier, which excludes the first N bits) for inclusion in the paging message. The first N bits are extracted and used separately for paging time determination, allowing the paging message to contain minimal necessary information for terminal identification.
2Measurement precision
If the paging message contains complete identifier information, then terminal identification is accurate, but the message size increases
Solution Approach 1:
The identifier information is segmented such that the first N bits determine paging time while the remaining bits form the second identifier included in the paging message. This segmentation reduces the message length by excluding redundant bits that are already used for time determination.
Solution Approach 2:
The patent extracts only the essential identification bits (second identifier) from the complete identifier, excluding the first N bits that are used for paging time calculation. This extraction reduces the message length while preserving sufficient information for accurate terminal identification.
3Reliability
If more bits are used for identifier in paging message, then terminal identification reliability improves, but communication efficiency decreases
Solution Approach 1:
The identifier is segmented into time-determination bits and identification bits, allowing the system to use minimal necessary bits for each function. This segmentation improves communication efficiency by reducing the number of bits transmitted in the paging message while maintaining identification reliability through the use of the second identifier.
Solution Approach 2:
The patent extracts only the essential identification portion (second identifier) from the complete identifier for inclusion in the paging message. This extraction reduces the bit length transmitted over the air interface, thereby improving communication efficiency while maintaining sufficient identification reliability through the unique properties of the second identifier.

AI summary
The present application provides paging methods and devices, which can reduce signaling overhead. A method comprises: determining a paging time of a first terminal device by using at least one first bit of a first identifier of the first terminal device; transmitting a paging message during the paging time; where the paging message carries identifier information of the first terminal device, and the identifier information is obtained based on at least one second bit, except the at least one first bit, of the first identifier of the first terminal device, or, the identifier information is obtained based on a second identifier of the first terminal device, where a length of the identifier information is shorter than the second identifier of the first terminal device.
