Terminal Wake-Up Period Adjustment via Network Retransmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless terminals face inefficiencies in power management due to fixed wake-up periods set by networks, leading to unnecessary power consumption and reduced standby times, as they cannot adaptively adjust their wake-up periods based on network retransmission patterns.
Innovation Solution
The method involves determining if a network side device retransmits a paging message, acquiring the retransmission interval and frequency, and adjusting the wake-up period of the terminal to a multiple of this interval, allowing it to synchronize with network retransmissions and reduce unnecessary wake-ups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the terminal uses a fixed wake-up period set by the network, then the terminal can reliably receive paging messages, but the terminal experiences unnecessary power consumption due to waking up even when no messages need processing
Solution Approach 1:
The patent applies dynamics by making the wake-up period adjustable rather than fixed. The terminal dynamically changes its wake-up period based on the actual paging message delivery situation, transitioning from a static network-configured period to a dynamic adaptive period that responds to real-time conditions.
Solution Approach 2:
The patent implements feedback by having the terminal monitor whether paging messages are actually delivered to it. Based on this feedback information about message delivery status, the terminal adjusts its wake-up period accordingly, creating a closed-loop control system that optimizes power consumption while maintaining reliable reception.
2Duration of action of stationary object
If the terminal wakes up at every paging occasion according to the network-set DRX period, then the terminal ensures it does not miss any paging messages, but the standby time is reduced due to frequent wake-ups
Solution Approach 1:
The patent makes the wake-up period dynamic by allowing the terminal to adjust it based on actual paging message delivery patterns. When the terminal detects that paging messages are being retransmitted or that no messages are intended for it, it extends the wake-up period, thereby increasing standby time while maintaining reliable message reception.
Solution Approach 2:
The patent changes the parameter of wake-up period from a fixed network-configured value to an adjustable value that the terminal can modify. By changing this parameter based on detected paging message patterns, the terminal achieves longer standby time without sacrificing reception reliability.
3Loss of energy
If the network retransmits paging messages multiple times, then the paging delivery reliability is improved, but the terminal still wakes up at the original DRX period causing unnecessary power consumption
Solution Approach 1:
The terminal uses feedback from monitoring paging message delivery to adjust its wake-up behavior. When the terminal detects that paging messages are being retransmitted by the network, it uses this information to extend its wake-up period, avoiding unnecessary wake-ups while ensuring complete reception of retransmitted messages.
Solution Approach 2:
The terminal performs preliminary monitoring of paging message delivery patterns before making adjustments to its wake-up period. By detecting retransmission patterns in advance, the terminal can proactively adjust its wake-up schedule to align with actual message delivery timing, preventing unnecessary power consumption while maintaining complete message reception.

AI summary
The present invention discloses a method for adjusting a wake-up period of a terminal, an apparatus, a terminal, a computer program, and a storage medium. The method includes: determining whether a network retransmits a paging message in a current location area; if a paging message is retransmitted, acquiring a time interval at which the paging message is retransmitted and the number R of times that the paging message is retransmitted; and adjusting the wake-up period of the terminal to a value equal to N times (2 ≤N ≤ R) the time interval at which the paging message is retransmitted, so that when a network side device has the performance of retransmitting a paging message in the current location area, the terminal does not need to still wake up according to a DRX period set by the network side, thereby reducing electric energy consumption of the terminal and extending standby time.
