Dynamic Paging Power Adjustment for Mobile Station Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, mobile stations often experience latency and battery drain due to the need to frequently wake up to check for page messages, especially at lower paging slot frequencies, which can lead to missed page messages and inefficient power usage.
Innovation Solution
The wireless serving network dynamically adjusts paging transmission power based on the mobile station's paging slot frequency, using higher power for higher slot frequencies and lower power for lower slot frequencies to ensure prompt message receipt and reduce latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If mobile stations wake up frequently to check for page messages, then connection establishment speed is improved, but battery power is drained faster
Solution Approach 1:
The system dynamically adjusts the paging slot frequency based on network conditions and mobile station behavior. Mobile stations can switch between different slot cycle indexes (SCIs) to balance between connection establishment speed and power consumption, allowing the paging mechanism to adapt to varying operational requirements rather than using a fixed slot frequency
Solution Approach 2:
The invention changes the paging slot frequency parameter (slot cycle index) to optimize the balance between connection establishment speed and power consumption. By adjusting this parameter, the system can achieve faster connection establishment when needed while reducing power consumption during normal operation, directly addressing the technical contradiction
2Loss of time
If mobile stations wake up frequently to check for page messages, then latency is reduced, but power consumption increases
Solution Approach 1:
The system implements dynamic paging slot frequency adjustment where mobile stations can transition between different slot cycle indexes based on network conditions. This allows the system to reduce paging latency when needed while minimizing power consumption during periods of low activity, effectively balancing these two opposing requirements
Solution Approach 2:
By changing the slot cycle index parameter, the system optimizes the trade-off between paging latency and power consumption. Lower SCIs provide faster paging response but higher power consumption, while higher SCIs reduce power consumption but increase latency. The invention allows dynamic adjustment of this parameter to achieve optimal performance
3Use of energy by moving object
If lower paging slot frequencies are used to save power, then battery drain is reduced, but page message delivery reliability deteriorates
Solution Approach 1:
The system dynamically adjusts paging slot frequency based on network conditions and mobile station behavior patterns. When reliability is critical, the system can switch to lower slot cycle indexes for more frequent paging opportunities. When power conservation is the priority, it can use higher slot cycle indexes. This dynamic adaptation ensures reliable page message delivery while optimizing power consumption
Solution Approach 2:
The invention changes the slot cycle index parameter to balance power consumption and page message delivery reliability. By adjusting this parameter, the system can ensure that page messages are delivered reliably even when mobile stations wake up less frequently, addressing the contradiction between power conservation and delivery reliability

AI summary
A mechanism for dynamically setting paging transmission power for a given mobile station based on the mobile station's paging slot frequency. For a mobile station that is set to operate at a higher paging slot frequency (e.g., lower slot cycle index), a wireless serving network transmits a page message to the mobile station at a higher power level, in order to increase the likelihood that the mobile station will successfully receive the page message. On the other hand, for a mobile station that is set to operate at a lower paging slot frequency (e.g., a higher slot cycle index), the network transmits a page message at a lower power level.
