Paging Early Indication for Inactive Multicast Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies do not support the reception of inactive multicast services, leading to unnecessary power consumption in terminals due to ineffective paging mechanisms, and lack a solution for updating multicast service configurations in inactive states.
Innovation Solution
Implementing a paging early indication (PEI) system that informs terminals whether to monitor paging messages related to inactive multicast services, reducing unnecessary monitoring and power consumption by using PEI configurations and RNTIs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminals continuously monitor paging messages for inactive multicast services, then service reception reliability is improved, but power consumption increases
Solution Approach 1:
The network device performs preliminary action by transmitting PEI indication information before the actual paging message, allowing the terminal to advance knowledge of whether paging information exists. This preliminary notification enables the terminal to prepare accordingly - either by activating monitoring for reliable reception or by entering power-saving mode when no paging is expected, thus resolving the contradiction between reliability and power consumption.
Solution Approach 2:
The PEI mechanism establishes a feedback loop where the network device provides advance indication about paging message presence, and the terminal responds by adjusting its monitoring behavior. This feedback mechanism allows dynamic optimization of power consumption based on actual paging needs while maintaining service reception reliability when paging occurs.
2Adaptability or versatility
If terminals monitor paging messages for inactive multicast services, then service update capability is improved, but device complexity increases
Solution Approach 1:
The network device transmits PEI indication information in advance before the actual paging message, providing preliminary knowledge of whether service updates are upcoming. This allows the terminal to simplify its monitoring logic by only actively monitoring when PEI indicates paging presence, rather than continuously monitoring, thus reducing device complexity while maintaining service update capability.
Solution Approach 2:
The paging monitoring process is segmented into two distinct phases: the PEI indication phase (where the terminal receives advance notification) and the actual paging message phase (where the terminal monitors only if needed). This segmentation simplifies the terminal's operational logic by dividing the monitoring function into conditional activation rather than continuous operation.
3Reliability
If the network device transmits paging information continuously, then service reception reliability is improved, but network resource consumption increases
Solution Approach 1:
The network device performs preliminary action by transmitting PEI indication information before the actual paging message. This preliminary transmission allows the network to efficiently allocate resources by only sending complete paging messages when necessary, rather than continuously transmitting paging information, thus reducing network resource consumption while maintaining service reception reliability through targeted paging transmissions.
Solution Approach 2:
The PEI mechanism extracts the essential paging notification function from the full paging message transmission. By separating the indication of paging presence (PEI) from the actual paging message content, the network can transmit minimal information to trigger terminal monitoring only when necessary, thereby reducing overall network resource consumption while preserving reliability for actual service updates.
