Wireless Serving Node Proxy for Mobile Server Message Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face inefficiencies due to frequent server messages, such as keepalive requests, which increase signaling overhead and battery consumption in mobile devices, and are difficult to control as they are often managed by separate organizations within the network.
Innovation Solution
Implementing a proxy within the wireless network, such as a servicing node, to receive and respond to server requests on behalf of mobile stations, reducing the need for mobile devices to handle frequent keepalive and connection management messages by using inactivity timers and message conversions to minimize signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequent server messages (e.g., keepalive requests) are sent to mobile stations, then connection reliability is maintained, but network overhead and battery consumption increase
Solution Approach 1:
The patent introduces a serving node as an intermediary between the network server and mobile station. This intermediary receives server requests, determines whether to forward them based on local inactivity timers, and can respond on behalf of the mobile station, thereby reducing the frequency of messages reaching the mobile device and lowering its energy consumption while maintaining connection reliability
Solution Approach 2:
The serving node performs preliminary actions by maintaining local inactivity timers and pre-evaluating server requests before they reach the mobile station. By determining in advance whether a request needs to be forwarded, the system avoids unnecessary message transmissions to the mobile device, reducing battery consumption while preserving connection stability
2Reliability
If frequent server messages are sent to mobile stations, then connection status is monitored accurately, but signaling overhead increases
Solution Approach 1:
The serving node acts as a mediator that filters and manages signaling traffic. It receives server requests, uses local inactivity timers to determine connection status, and selectively forwards or responds to messages, thereby maintaining accurate connection monitoring while significantly reducing the quantity of signaling messages transmitted through the network
Solution Approach 2:
The system applies partial action by not forwarding every server request to the mobile station. Instead, the serving node selectively forwards only necessary requests and handles routine status checks itself, reducing signaling overhead while maintaining sufficient connection status monitoring accuracy
3Ease of operation
If mobile devices handle frequent keepalive messages directly, then connection control is simple, but device complexity and battery consumption increase
Solution Approach 1:
The serving node serves as an intermediary that absorbs the complexity of message filtering and inactivity timer management. Mobile devices maintain simple connection handling while the serving node performs the complex evaluation of whether to forward server requests, effectively shifting device complexity to the network infrastructure
4Adaptability or versatility
If separate organizations manage server messages independently, then organizational autonomy is maintained, but coordination and efficiency decrease
Solution Approach 1:
The serving node provides universal functionality by serving multiple purposes: it acts as a proxy for mobile stations, maintains local inactivity timers, filters server requests, and reduces signaling overhead. This multi-functional approach allows different network entities to maintain their autonomy while achieving coordinated efficiency through the serving node's centralized message management capabilities

AI summary
An apparatus and method for reducing frequent server messages including receiving a server request from a network server intended for a mobile station; determining whether to forward the server request to the mobile station; and transmitting a server response to the network server based at least in part on the server request on behalf of the mobile station.
