Dynamic Paging Concatenation for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular wireless communication systems, the scarcity of paging channel resources leads to congestion, which can delay or prevent successful paging of mobile stations, especially during multiple attempts to establish communication.
Innovation Solution
The method involves dynamically selecting a concatenation level for page messages based on the paging-attempt status and the type of mobile station, allowing for varying levels of page record concatenation in General Page Messages to optimize transmission efficiency and increase the chances of successful paging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple page records are concatenated in a single page message to reduce the number of transmissions, then the paging channel load is reduced, but the complexity of processing and delivering page records increases
Solution Approach 1:
The patent segments page records into different types (first page records and second page records) with different concatenation levels. First page records can be concatenated at higher levels to maximize channel efficiency, while second page records use lower concatenation levels to simplify processing. This segmentation allows the system to optimize between productivity and complexity by treating different page records differently.
Solution Approach 2:
The patent applies different concatenation qualities to different parts of the page message. Instead of uniform concatenation, the system uses variable concatenation levels based on the specific requirements of each page record type. This local differentiation allows optimal performance for each segment while managing overall system complexity.
2Reliability
If the paging channel transmits more page records simultaneously to improve paging success rate, then the coverage of paging is improved, but the paging channel becomes more congested
Solution Approach 1:
The patent segments page records into two categories: first page records (for mobile stations not yet paged) and second page records (for mobile stations that require re-paging). This segmentation allows the system to prioritize different types of paging operations, transmitting first page records with higher concatenation levels to maximize initial coverage, while handling second page records with adjusted concatenation to manage channel load and avoid congestion.
3Ease of manufacture
If the system uses fixed concatenation levels for all page messages, then the implementation is simpler, but the adaptability to different paging scenarios is reduced
Solution Approach 1:
The patent implements dynamic concatenation level selection based on the paging scenario. The system determines the appropriate concatenation level by considering factors such as whether it is a first or second page record, the mobile station's paging status, and the current channel conditions. This dynamic adjustment provides adaptability to different scenarios while maintaining relatively simple implementation through rule-based decision logic.
Solution Approach 2:
The patent changes the concatenation parameter dynamically based on paging attempt number and mobile station characteristics. The system adjusts the concatenation level as a variable parameter rather than using a fixed value, allowing optimization for different paging scenarios such as initial paging versus re-paging, while maintaining implementability through structured parameter adjustment rules.

AI summary
Disclosed herein are methods and systems for dynamically selecting a paging-concatenation level for a page based on one or more properties of the page. An exemplary method involves, at a wireless communication network that is configured to provide service to at least one wireless-communication device, using at least one property of a page record as a basis for selecting a paging-concatenation level for the page record, and paging the wireless-communication device by transmitting a page message that includes the page record, wherein the page message is of the selected paging-concatenation level. Various properties of the page record, such as the paging-attempt status and/or the target mobile station of the page, among others, may be used to select the paging-concatenation level.
