Wireless Prohibit Timer Handling During Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the handling of a running prohibit timer upon reception of a reconfiguration message is not specified, leading to unclear operations and potential signaling overhead due to frequent UE-originated indications.
Innovation Solution
A method and apparatus for configuring a timer in a wireless communication system, where a user equipment (UE) transmits a first indication, starts a timer to prohibit further indications, receives a second configuration, and configures the indication according to the second configuration after the timer expires, allowing clear handling of a running prohibit timer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a prohibit timer is configured to prevent frequent UE-originated indications, then signaling overhead is reduced, but the handling of reconfiguration messages during timer operation becomes ambiguous and complex
Solution Approach 1:
The patent applies preliminary action by pre-defining the timer behavior in the specification before the ambiguity arises in practice. The standard explicitly states that upon receiving a reconfiguration message during timer operation, the UE shall restart the prohibit timer with the new configuration parameters. This preliminary definition eliminates the need for complex runtime decision-making logic in the UE, as the behavior is predetermined and clearly specified in the standard.
Solution Approach 2:
The patent applies dynamics by making the prohibit timer configurable and restartable based on received reconfiguration messages. Instead of a fixed static timer, the system allows dynamic adjustment of timer parameters through RRC reconfiguration, enabling the network to adapt the timer behavior to different scenarios while maintaining clear operational rules.
2Reliability
If the prohibit timer is restarted upon receiving reconfiguration messages, then the timer handling becomes clear and unambiguous, but the timer may run longer than initially intended increasing power consumption
Solution Approach 1:
The patent resolves this contradiction by preliminarily specifying in the standard that when a reconfiguration message is received during timer operation, the UE shall restart the prohibit timer. This clear preliminary definition ensures reliable and unambiguous timer operation, eliminating the need for complex runtime judgment logic in the UE that would otherwise be required to determine whether to restart or continue the existing timer.
Solution Approach 2:
The patent applies parameter changes by allowing the prohibit timer value to be dynamically adjusted through reconfiguration messages. The network can modify the timer parameters based on current system conditions and UE behavior patterns, optimizing the balance between preventing excessive signaling and managing power consumption according to actual network needs.
