Dynamic Page-Response Interval Management in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The disparity in page-response intervals between different cellular wireless networks, such as 4G LTE and 3G CDMA, leads to inconsistent call setup times for mobile stations, affecting user experience when receiving incoming communications.
Innovation Solution
A method and apparatus for dynamically managing page-response intervals based on the air interface and protocol used for paging, allowing networks to adjust the interval based on whether the communication is to be provided over the same or a different air interface, ensuring consistent paging efforts across various networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If different networks use their own native page-response intervals, then each network optimizes its own paging efficiency, but call setup time becomes inconsistent across networks
Solution Approach 1:
The patent dynamically changes the page-response interval parameter based on the air interface type. When paging over LTE air interface, a shorter interval (e.g., 2 seconds) is used, while when paging over CDMA air interface, a longer interval (e.g., 5 seconds) is used. This parameter adaptation resolves the contradiction by optimizing paging efficiency for each network type while maintaining consistent call setup time across different networks.
2Reliability
If a network uses a longer page-response interval, then the network has more time to wait for mobile station response, but the overall call setup time increases
Solution Approach 1:
The patent makes the page-response interval dynamic rather than fixed. The interval is adjusted based on the air interface type used for paging. This dynamic adaptation allows the system to maintain reliable waiting time for page responses while minimizing overall call setup time by selecting the appropriate interval duration for each specific paging scenario.

AI summary
A method and apparatus for managing page-response intervals. When a network entity receives a paging trigger signal, the entity determines a page-response interval to use for paging the mobile station, based on one or more factors such as (i) whether the communication is to be provided to the mobile station over the same air interface and/or same air interface protocol that will carry the paging to the mobile station and/or (ii) what network, interface, or other entity the trigger signal comes from and/or what network communication module receives the trigger signal. The network entity then uses the determined page-response interval when paging the mobile station, waiting that determined period of time after each page attempt before attempting to page again or before concluding that the paging effort failed.
