Dynamic Page Concatenation for SRLTE Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-radio LTE (SRLTE) devices experience reduced LTE throughput due to periodic disconnection from the LTE network to check for page messages from CDMA networks, which can be exacerbated by page concatenation features that reduce paging success rate and increase tune-away time.
Innovation Solution
Implementing a method to selectively disable or reduce page concatenation for SRLTE devices, allowing them to use different page-concatenation levels based on their configuration and paging attempt status, thereby optimizing their connection time and resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If page concatenation feature is applied to concatenate pages to multiple UEs in a single page message, then paging channel resource efficiency is improved, but paging success rate deteriorates and SRLTE devices experience increased tune-away time
Solution Approach 1:
The patent applies different page concatenation configurations to different UEs based on their radio capability. SRLTE devices receive pages with concatenation level 0 (no concatenation) while other devices can receive concatenated pages, allowing localized optimization for each device type
Solution Approach 2:
The patent dynamically selects page concatenation level based on the target UE's radio capability and paging attempt status. The network entity determines whether to concatenate pages by evaluating device characteristics, enabling adaptive paging strategy that balances resource efficiency and success rate
2Adaptability or versatility
If SRLTE devices periodically disconnect from LTE network to check for page messages from CDMA network, then voice call capability is maintained, but LTE throughput deteriorates
Solution Approach 1:
The patent extracts the paging function for SRLTE devices from the concatenated page messages and handles it separately. By sending individual unconcatenated pages to SRLTE devices, the system isolates their specific requirements from the general concatenated paging process, reducing the need for prolonged tune-away periods
Solution Approach 2:
The patent changes the page concatenation parameter specifically for SRLTE devices, setting concatenation level to 0. This parameter change reduces page message complexity and size, enabling faster page reception and processing, thereby reducing tune-away time and improving LTE throughput

AI summary
Methods and systems disclosed herein can help to dynamically adjust the degree of or enable/disable concatenation of page messages, depending upon whether a user equipment is operating as a single radio LTE (SRLTE) device. An exemplary method involves a radio access network: (i) determining that a UE is configured to use a single radio system for both (a) data communication under a first air interface protocol, and (b) voice calls under a second air interface protocol that is different from the first air interface protocol, (ii) based at least in part on the determination, selecting a page-concatenation level to be used to page the first UE, and (iii) transmitting at least on page message to the UE according to the selected page-concatenation level.
