Dynamic Paging Concatenation for Voice and Data Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The paging success rate (PSR) in cellular wireless communication systems is lower for data pages and intersystem pages due to congestion and mobility issues, leading to delayed or failed page delivery.
Innovation Solution
Dynamically adjusting the concatenation of pages based on their type, disabling or reducing concatenation for data pages and intersystem pages to improve the PSR by enabling or disabling page concatenation before transmission, depending on whether the page is a voice-service, data-service, or intersystem page.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pages are concatenated to conserve bandwidth and transmit more pages per timeslot, then the paging channel capacity increases, but the paging success rate decreases due to information loss and mobile station inability to receive concatenated pages
Solution Approach 1:
The patent implements dynamic concatenation control where the RAN determines page-type (voice-service, data-service, or intersystem) and selectively applies concatenation based on the specific page type. Voice-service pages are concatenated to maximize bandwidth efficiency, while data-service and intersystem pages are not concatenated to ensure reliable delivery. This dynamic adaptation resolves the contradiction by making concatenation conditional rather than universal.
2Productivity
If data pages and intersystem pages are concatenated, then more pages can be transmitted per timeslot, but information is lost and mobile stations cannot receive these pages effectively
Solution Approach 1:
The patent applies different concatenation treatments to different page types based on their specific requirements. Voice-service pages receive concatenation treatment for efficiency, while data-service and intersystem pages are excluded from concatenation to preserve their information integrity. This localized quality control ensures that concatenation is applied only where appropriate without causing information loss in sensitive page types.
3Reliability
If voice pages are given priority over data pages during congestion, then voice service reliability is maintained, but data page delivery is delayed or failed
Solution Approach 1:
The patent segments the paging channel into different treatment categories based on page-type. By identifying and separating data-service pages and intersystem pages from voice-service pages, the system can apply different concatenation rules to each segment. This segmentation allows data pages to be transmitted without concatenation (ensuring delivery) while voice pages receive concatenation treatment (ensuring efficiency during congestion).

AI summary
Exemplary methods and systems for paging a mobile station are disclosed herein. An exemplary method involves: (i) before transmission of a page to a mobile station by an access network, the access network (a) determining a page-type of the page to the mobile station; (b) based at least in part on the page-type, determining whether to disable or enable page-concatenation for the page; and (c) if concatenation is enabled, then concatenating the page, and otherwise refraining from concatenating the page; and (ii) the access network transmitting the page to the mobile station. In an exemplary embodiment, determining the page-type of the page may involve determining whether the page is a voice-service page or a data-service page and/or determining whether or not the page is an intersystem page. Further, concatenation may be enabled if the page is a voice-service page, and disabled if the page is a data-service page. Yet further, concatenation may be disabled if the page is an intersystem page (preferably regardless of whether the intersystem page is a voice-service or data-service page).
