Adaptive Paging Message Bundling for Mobile Network Signaling Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile telecommunications networks face increased traffic and signaling load, leading to inefficiencies in network capacity and user experience, particularly due to the need for frequent paging messages that cause radio access network (RAN) signaling events, which are resource-intensive and impact battery life.
Innovation Solution
Implementing an adaptive and selective bundling mechanism for downlink paging messages, where a Mobility Management Entity (MME) determines whether to delay or initiate the paging procedure based on data flow sensitivity, quality of service (QoS) category, signaling load, and device bundling state, allowing for caching of messages and controlled timer management to optimize resource usage.

Engineering Contradiction Analysis
1Reliability
If frequent paging messages are sent to mobile devices, then network responsiveness and user experience are improved, but RAN signaling load and battery consumption increase
Solution Approach 1:
The patent combines multiple downlink paging messages into a single bundled paging message that is sent to the mobile device. Instead of transmitting separate paging messages for different data flows, the system merges them into one consolidated message containing multiple data flow indicators, thereby reducing the number of signaling events and minimizing battery consumption while maintaining network responsiveness.
Solution Approach 2:
The patent implements periodic bundling of paging messages based on timing relationships between data flows. By organizing paging messages into periodic bundles and using discontinuous reception (DRX) cycles, the system reduces the frequency of individual paging transmissions while ensuring that mobile devices are still notified of downlink data availability, thus balancing responsiveness with energy conservation.
2Loss of energy
If paging procedures are delayed to bundle messages, then signaling load is reduced, but data delivery latency increases for delay-sensitive flows
Solution Approach 1:
The patent applies different quality treatments to different data flows within the same paging bundle. By identifying delay-sensitive data flows and marking them appropriately, the system ensures that these critical flows are handled with higher priority and shorter latency requirements, while non-delay-sensitive flows can tolerate longer bundling delays. This local differentiation allows selective optimization without compromising overall system performance.
Solution Approach 2:
The patent dynamically adjusts the bundling behavior based on the characteristics of individual data flows. The system monitors data flow properties such as delay sensitivity and QoS requirements, and adaptively determines whether to bundle messages or send them individually. This dynamic approach allows the system to optimize signaling load when possible while ensuring timely delivery when required by service quality requirements.
3Productivity
If adaptive bundling is implemented, then resource efficiency is improved, but device complexity increases
Solution Approach 1:
The patent enables mobile devices to self-determine their bundling capability and preferences. The device includes a bundling state determination module that autonomously assesses whether it supports paging message bundling and communicates this capability to the network. This self-service approach shifts part of the complexity from the network side to the device side, allowing the MME to simply respond to device capabilities without implementing complex bundling logic, thereby reducing overall system complexity while maintaining resource efficiency.
Data Source
AI summary
Concepts and technologies are described herein for adaptive and selective bundling of downlink paging messages. According to one aspect disclosed herein, a mobility management entity (“MME”) can determine whether to delay a paging procedure to deliver a downlink paging message to a mobile device served by the MME. If the MME determines that the paging procedure to deliver the downlink paging message to the mobile device should be delayed, then the MME can store the downlink paging message in a bundling cache. If the MME determines that the paging procedure to deliver the downlink paging message to the mobile device should not be delayed, then the MME can initiate the paging procedure.
