Paging Indicator Signal for Wireless State Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunication systems experience latency due to frequent state changes in access modes and signaling protocols, which is undesirable for mobile terminals requiring rapid mode transitions.
Innovation Solution
A receiver that operates by receiving a Paging Indicator Signal to perform direct transitions between access modes and states, eliminating the need for additional signaling, and time-multiplexing the Paging Indicator Signal with data signals on a single channel to reduce latency and simplify system architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional paging and signaling protocols are used for state changes, then network access control is maintained, but latency increases due to frequent signaling exchanges
Solution Approach 1:
The system pre-configures multiple access modes (CELL_DCH, CELL_PCH, URA_PCH, IDLE) with all necessary parameters and resources before they are needed. When a state change is required, the terminal can immediately switch to the pre-configured mode without performing additional signaling exchanges, thus reducing latency while maintaining network control through the pre-established configuration framework
2Reliability
If multiple signaling protocols are used for access mode transitions, then proper state management is achieved, but device complexity increases
Solution Approach 1:
The invention creates a universal state management framework where a single paging message structure can trigger transitions to multiple different access modes (CELL_DCH, CELL_PCH, URA_PCH, IDLE) depending on the configured parameters. This multi-functional approach simplifies the overall system by replacing multiple specialized signaling protocols with one unified mechanism that handles all state transitions
Solution Approach 2:
The system manages state transitions by changing parameters within the paging message configuration rather than using different signaling protocols for each state change. The paging message contains configurable parameters that determine the target access mode and associated resources, allowing flexible state management through parameter modification rather than protocol complexity
3Loss of time
If direct state transitions are implemented without additional signaling, then latency is reduced, but system control and monitoring capability deteriorates
Solution Approach 1:
The network pre-configures all necessary access parameters, resources, and control policies for each access mode before the terminal needs to transition. This preliminary configuration ensures that when a direct state transition occurs without additional signaling, the system maintains full control because the transition targets and parameters were already approved and configured by the network
