DPI Idle Mode Agent Prioritizing Paging Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-speed mobile wireless networks, conventional paging processes result in high signaling load bursts, consuming network resources and impacting performance, due to the lack of knowledge about the nature of paging activities, which crude rate limiting cannot adequately address.
Innovation Solution
Implementing a deep packet inspection (DPI) idle mode agent that prioritizes and categorizes paging messages by comparing downstream traffic with a predefined list of legitimate push applications, directing high-priority messages immediately and low-priority messages to wait, thereby optimizing network resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional paging processes are used to wake up idle mobile devices, then mobile devices can receive downstream data, but high signaling load bursts occur that consume network resources and degrade performance
Solution Approach 1:
The patent changes the parameter of paging message handling from uniform treatment to differentiated treatment based on application type. By introducing application identification and categorization, the system transforms paging messages into different priority queues (high priority for legitimate push applications, low priority for other applications), thereby resolving the contradiction between reliable data delivery and network performance.
2Productivity
If rate limiting is applied to paging messages to reduce signaling load, then network resource consumption decreases, but the network becomes sluggish due to crude rate limiting without knowledge of paging activity nature
Solution Approach 1:
The patent applies local quality by treating different paging messages differently based on their application-specific characteristics. Instead of uniform rate limiting, the system identifies legitimate push applications and provides them with preferential treatment (high priority queue), while applying stricter limits to other applications (low priority queue). This localized differentiation resolves the contradiction between resource efficiency and network responsiveness.
3Device complexity
If all paging messages are treated equally without categorization, then simple processing is maintained, but legitimate push applications cannot receive enhanced response times during high load
Solution Approach 1:
The patent applies preliminary action by pre-categorizing paging messages into high and low priority queues based on application identification before processing. By performing application identification and queue assignment in advance, the system enables legitimate push applications to receive preferential treatment during high load conditions, resolving the contradiction between processing simplicity and response time without adding significant complexity.

AI summary
A network configuration capable of prioritizing and categorizing paging messages using a deep packet inspection (“DPI”) idle mode agent (“IMA”) is disclosed. In one embodiment, upon redirecting a downstream packet stream to a DPI agent after discovery of destination end user (“EU”) equipment is in an idle mode, the legitimacy of the downstream packet stream is determinate in accordance with previously stored information. The downstream packet stream is subsequently categorized to a high priority paging category, a medium priority paging category, or a low priority paging category in response to the legitimacy of the downstream packet stream.
