Stationary UE Paging Control to Reduce Power and Radio Resource Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to reduce power consumption and waste of radio resources in stationary fixed UEs by optimizing paging transmissions in idle mode.
Innovation Solution
A method where UEs transmit a connection establishment request message to a base station, including mobility information indicating they are stationary, and the base station configures them to avoid measuring neighboring base stations, thereby reducing unnecessary power consumption and resource waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE performs paging transmission to all base stations in idle mode, then the UE can receive notifications from any base station, but the power consumption increases and radio resources are wasted
Solution Approach 1:
The patent applies local quality by differentiating the paging transmission behavior based on the UE's mobility state. For stationary UEs, the system transmits paging only to the serving base station rather than all base stations, while for mobile UEs, paging is transmitted to all base stations. This localized differentiation optimizes power consumption for stationary UEs while maintaining comprehensive notification coverage for mobile UEs.
Solution Approach 2:
The patent implements dynamics by making the paging transmission strategy adaptive to the UE's mobility state. The system dynamically adjusts the paging transmission scope based on whether the UE is identified as stationary or mobile, allowing the network to optimize resource allocation and power consumption according to actual UE behavior patterns.
2Adaptability or versatility
If the UE measures neighboring base stations for mobility optimization, then the network can improve connection management, but unnecessary power consumption occurs for stationary UEs
Solution Approach 1:
The patent applies local quality by implementing different measurement behaviors based on UE mobility state. Stationary UEs are configured to skip neighboring cell measurements while mobile UEs perform full measurement procedures. This localized differentiation ensures that measurement resources are allocated only where necessary, reducing power consumption for stationary UEs while maintaining connection management adaptability for mobile UEs.
Solution Approach 2:
The patent implements partial action by having stationary UEs skip unnecessary neighboring cell measurement procedures. Instead of requiring full measurement capabilities for all UEs, the system applies measurement functions only to mobile UEs that need them, thereby reducing overall power consumption while maintaining adequate connection management for the subset of mobile users.
3Reliability
If the network transmits paging to unspecified base stations for stationary UE, then coverage is ensured, but radio resources are wasted
Solution Approach 1:
The patent applies local quality by tailoring paging transmission scope to UE mobility characteristics. For stationary UEs, paging is transmitted only to the serving base station, while for mobile UEs, paging is transmitted to all base stations. This localized differentiation ensures paging delivery reliability for stationary UEs without wasting radio resources on unnecessary transmissions to other base stations.
Solution Approach 2:
The patent implements segmentation by dividing the UE population into stationary and mobile categories and applying different paging strategies to each segment. This segmentation allows the network to optimize paging resource allocation by treating stationary and mobile UEs differently, reducing overall radio resource waste while maintaining reliable paging delivery to both groups.

AI summary
A method performed by a UE in a wireless communication system is provided. The method includes transmitting a UE capability information message including information indicating that the UE is in a fixed state, based on the information included in the UE capability information message, receiving, from the base station, a first radio resource control (RRC) message including information for configuring the UE not to perform a measurement for a signal strength of a neighbor base station, transmitting, to the base station, a second RRC message as a response to the first RRC message, receiving a third RRC message for transitioning the UE to an RRC idle state, based on the third RRC message, transitioning to the RRC idle state, and receiving a paging message in the RRC idle state, the UE in the fixed state receives the paging message from the base station which the UE performed the last access.
