Gateway Device Consolidates Application Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for cellular radio access networks generate excessive control traffic between policy control server devices and gateway devices, leading to processing overload and throughput issues due to frequent application start and stop notifications.
Innovation Solution
Implementing techniques where the gateway device sends consolidated messages, such as a single CCR-U message for both application start and stop notifications, and only notifies the policy control server of application starts and stops once per IP connectivity access network session, reducing the number of messages exchanged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the gateway device sends individual messages for each application start and stop notification, then the policy control server device receives complete application detection information, but the control traffic volume increases and processing demands increase
Solution Approach 1:
The patent combines multiple application detection notifications (application starts and stops) into a single consolidated message. Instead of sending separate messages for each application event, the gateway device aggregates multiple events and sends them together in one message, thereby reducing control traffic volume while maintaining complete information delivery to the policy control server device.
2Speed
If the gateway device sends individual messages for each application start and stop notification, then the policy control server device receives timely application detection information, but the processing demands and message processing delays increase
Solution Approach 1:
The patent merges multiple application detection notifications into a single consolidated message, reducing the total number of messages that need to be processed. This approach maintains timely information delivery while significantly improving message processing efficiency by reducing the processing load on both the gateway device and the policy control server device.
3Measurement precision
If the gateway device sends messages for each packet flow application start and stop, then the policy control server device receives detailed flow-level application information, but the control traffic volume increases excessively
Solution Approach 1:
The patent combines application detection notifications from multiple packet flows into a single consolidated message. The gateway device tracks application starts and stops across different packet flows and aggregates these notifications, sending them together in one message. This maintains precise application detection information while dramatically reducing control traffic volume compared to sending separate messages for each packet flow event.

AI summary
In one example, a gateway device includes one or more processors configured to determine that a subscriber device has started a first application, determine that the subscriber device has ended a second application, and send a message, in accordance with Diameter protocol, to a policy server device indicating both that the subscriber device has started the first application and that the subscriber device has ended the second application. In another example, a gateway device includes one or more processors configured to send at most one message, in accordance with Diameter protocol, to a policy server device indicating that a subscriber device has started an application, and at most one message, in accordance with the Diameter protocol, indicating that the subscriber device has stopped the application.
