Proxy Device Paging for Idle Wireless Clients
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in minimizing power consumption for client devices operating in idle mode, as they continue to cycle their receivers to monitor for paging messages, leading to significant power usage, and proxy devices cannot simultaneously support both active and idle mode operations, resulting in reduced power savings and increased signaling messages.
Innovation Solution
The system allows a proxy device to monitor a channel associated with an active connected mode client device to deliver paging messages to idle mode clients, enabling the idle mode clients to enter active mode independently and re-register with the proxy device upon completion of calls, while the proxy device continues to support both active and idle mode operations for multiple clients.

Engineering Contradiction Analysis
1Reliability
If client devices cycle their receivers to monitor for paging messages in idle mode, then they can receive incoming calls and control messages, but power consumption increases significantly
Solution Approach 1:
A proxy device is introduced as an intermediary between the network and idle mode client devices. The proxy device monitors paging messages on behalf of multiple idle mode clients and selectively wakes up only those clients that have incoming calls or control messages, rather than having all clients continuously monitor the paging channel. This mediator approach reduces overall power consumption while maintaining reliable message delivery.
Solution Approach 2:
The proxy device performs multiple functions: it monitors paging messages for multiple idle mode clients simultaneously, determines which clients need to be woken up, and facilitates their connection to the network. This multi-functional approach allows a single proxy device to serve multiple clients, reducing the total number of receivers that need to be cycled on and off.
2Use of energy by moving object
If a proxy device supports active mode operation for one client device, then it can facilitate reduced power consumption through short range wireless links, but it cannot simultaneously monitor paging information for other idle mode proxied client devices
Solution Approach 1:
The system dynamically adjusts the proxy device's monitoring behavior based on the operational state of connected clients. When a client is in active mode, the proxy uses short range wireless links to facilitate communication while maintaining the ability to monitor paging channels for other idle clients. The proxy adapts its resource allocation and monitoring priorities to accommodate both active and idle mode operations simultaneously.
Solution Approach 2:
The proxy device segments its functionality to handle active mode clients and idle mode clients separately but concurrently. It maintains dedicated resources for monitoring paging messages for idle clients while simultaneously managing active client connections through short range wireless links. This segmentation allows independent optimization of power consumption for each client type without interfering with the other.
3Reliability
If the proxy device releases idle mode proxied client devices when an active connected mode device enters connected state, then the active device can establish connection, but the released device must re-connect to the proxy device, increasing signaling messages
Solution Approach 1:
The proxy device maintains continuous monitoring of paging channels and control messages for idle mode clients even when active mode clients are connected. This preliminary action ensures that when an idle client needs to be woken up, the paging information is already ready and can be delivered immediately without requiring the client to re-establish connection to the proxy. The proxy proactively manages the connection state to minimize signaling overhead.
Solution Approach 2:
The system implements feedback mechanisms where the proxy device continuously monitors the connection state of both active and idle clients and adjusts its behavior accordingly. When a client transitions between modes, the proxy receives feedback about the new state and modifies its resource allocation and monitoring priorities to optimize both connection establishment and power consumption, reducing unnecessary re-connection signaling.

AI summary
Proxy devices simultaneously support multiple modes of client device operation. Embodiments facilitate continued support of idle mode, proxy state operation of one or more client devices by a proxy device that is serving an active connected mode proxied client device. Paging message delivery from the proxy device to an idle mode proxied client device is facilitated by the proxy device monitoring a channel associated with the active connected mode proxied client device for a message (e.g., paging message) associated with the idle mode proxied client device.
