Terminal MO Backoff Control for Out-of-Coverage Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In discontinuous coverage scenarios, terminals waste power by transmitting MO data when out of network coverage, necessitating a power-saving method to prevent such transmissions.
Innovation Solution
Implementing a power-saving mechanism where the terminal enters a MO backoff mode, preventing data transmission and signaling when out of network coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the terminal transmits MO data normally, then data communication is maintained, but power is wasted when out of coverage
Solution Approach 1:
The terminal dynamically adjusts its transmission behavior based on coverage status. When out of coverage, the terminal enters MO backoff mode which dynamically suppresses MO data transmission and signaling, preventing power waste while maintaining normal operation when in coverage
Solution Approach 2:
The terminal changes its operational parameters by entering a specific mode (MO backoff mode) with modified transmission characteristics. This mode parameter change causes the terminal to suppress MO data and signaling transmissions, thereby reducing power consumption when out of coverage
2Use of energy by moving object
If the terminal enters MO backoff mode, then power saving is achieved, but data transmission is prevented
Solution Approach 1:
The system provides dynamic control where the terminal can transition between normal operation mode and MO backoff mode based on coverage conditions. This dynamic switching allows the terminal to maintain full data transmission capability when in coverage while saving power when out of coverage
Solution Approach 2:
The terminal autonomously determines when to enter MO backoff mode by monitoring its own coverage status. When the terminal detects it is out of coverage, it automatically activates power saving mode without requiring external intervention, thereby extending battery life while maintaining normal functionality when needed

AI summary
Provided in one embodiment of the present disclosure is a method by which an AMF performs communication. The method comprises the steps of: receiving a registration request message from a user equipment (UE), wherein the registration request message includes capability information about a mobile originated (MO) backoff mode of the UE; determining that the UE is attempting to go outside the coverage of a serving cell; transmitting a registration accept message to the UE; and transmitting, on the basis of the determination, to the UE, an indication for allowing the MO backoff mode to be performed.
