Paging Response Using Pre-Configured Uplink Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Responding to paging information in mobile communication networks requires complex signaling, leading to increased power consumption and latency for mobile devices.
Innovation Solution
Utilizing pre-configured resources, such as Physical Uplink Shared Channel (PUSCH) resources, for mobile devices to respond to paging information, either through a random access procedure or directly on these resources, based on received indications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If regular signaling procedures are used to respond to paging information, then the mobile device can establish a connection for data transmission, but the signaling complexity increases and power consumption rises
Solution Approach 1:
The network pre-configures uplink resources (PUSCH) and associated signaling parameters for the UE before the UE needs to respond to paging. This preliminary configuration stored in the UE allows it to immediately use these pre-prepared resources when paging occurs, avoiding the need to perform complex signaling procedures at the moment of paging response.
2Reliability
If regular signaling procedures are used to respond to paging information, then the connection can be established, but the latency increases due to multiple signaling steps
Solution Approach 1:
All necessary signaling parameters and uplink resource allocations are prepared and stored in the UE in advance through pre-configuration. When paging occurs, the UE can directly activate these pre-configured resources and transmit the paging response immediately, eliminating the time required for multiple sequential signaling exchanges.
3Reliability
If complex signaling procedures are performed to respond to paging, then the connection can be established, but the power consumption of the mobile device increases
Solution Approach 1:
The UE receives and stores pre-configuration information including uplink resource allocations and signaling parameters during a connected state when power is abundant. When in idle state and paging occurs, the UE can directly use these pre-stored configurations to respond, avoiding the need to activate full signaling stacks and perform complex procedures that would consume significant power.
4Use of energy by moving object
If pre-configured resources are used for paging response, then power consumption and latency are reduced, but the resource allocation complexity increases for the network
Solution Approach 1:
The pre-configuration mechanism is designed to be universally applicable to all UEs in the network. The network uses standardized procedures and message formats (RRC Release, System Information) to configure multiple UEs with pre-configured uplink resources. This universal approach allows the network to manage resource allocation efficiently without requiring complex UE-specific handling, as the same mechanisms serve all users.
