Dormant Wireless Device Identification via Temporary Paging Zone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, dormant devices are difficult to identify and locate due to their reduced communication activity and registration states, which hinders efficient page delivery and network management.
Innovation Solution
A method and system where wireless communication devices associated with a first paging zone are instructed to associate with a temporary paging zone identifier, allowing the system to identify dormant devices by receiving indications of this identifier and subsequently instructing them to resume their original association, thereby enabling the detection and management of dormant devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wireless communication devices operate in dormant mode with reduced communication activity, then energy consumption is reduced and device battery life is extended, but the location and identity of dormant devices become unknown or undeterminable by the wireless communication system
Solution Approach 1:
The system performs preliminary actions by having devices register their presence in advance before actual communication occurs. Devices transmit their identity and location information during a preliminary registration phase, allowing the network to store this information proactively. When communication is needed, the network can immediately retrieve stored location data without needing to perform detection at the moment of communication, thus resolving the contradiction between energy saving and location detection capability.
Solution Approach 2:
The patent introduces an intermediary mechanism - a temporary paging zone identifier - that mediates between the dormant device state and network awareness. This intermediary allows devices to maintain a form of presence indication without full active communication. The temporary identifier acts as a bridge, enabling the network to track dormant devices through indirect means while devices maintain low-power operation, thus solving the detection difficulty without requiring continuous high-energy communication.
2Productivity
If the wireless communication system tracks all devices continuously to maintain accurate location records, then page delivery efficiency is improved, but network complexity and processing requirements increase
Solution Approach 1:
The system applies local quality by differentiating tracking requirements based on device state. Instead of uniformly tracking all devices with full complexity, the network implements selective tracking: active devices are tracked with full location and communication state, while dormant devices are tracked only with minimal identification information (such as temporary paging zone identifiers). This localized approach to tracking quality maintains page delivery efficiency for active devices while reducing overall network processing complexity through simplified dormant device management.
Solution Approach 2:
The patent segments device management into distinct categories based on operational state. Devices are divided into active and dormant groups, each managed through different mechanisms. Active devices receive full tracking and communication services, while dormant devices are managed through simplified registration and temporary identifiers. This segmentation allows the network to maintain accurate location records for pages delivery without applying full processing complexity to all devices, thus improving productivity while controlling system complexity.
3Difficulty of detecting and measuring
If dormant devices are identified through temporary paging zone identifiers, then device identification capability is improved, but the process requires additional system instructions and processing steps
Solution Approach 1:
The temporary paging zone identifier serves multiple functions simultaneously: it identifies dormant devices, maintains their location information, enables page routing, and facilitates device reactivation. By making this single identifier multi-functional, the system improves dormant device identification capability without proportionally increasing processing complexity. The universal nature of the identifier allows one data structure to fulfill multiple roles, reducing the need for separate processing steps for each function.
Solution Approach 2:
The patent merges multiple functions into the temporary paging zone identifier system. Device identification, location tracking, page routing, and state management are combined into a single integrated mechanism rather than separate processing steps. This merging approach improves identification capability while minimizing additional processing requirements, as the same data structure serves multiple purposes simultaneously, reducing overall system complexity.
