Inactive Multicast Bearer Release Based on Serving Cell Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication networks, terminals in an inactive state face challenges in receiving multicast services when switching from a connected state to an inactive state, particularly when moving out of the serving cell's coverage, necessitating a method to manage inactive multicast service configurations and radio bearers effectively.
Innovation Solution
The terminal releases or suspends the configuration and/or radio bearer of an inactive multicast service upon determining that the serving cell does not support it, and the network device sends a configuration indication to the terminal to manage these configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal maintains the inactive multicast service configuration when moving out of the serving cell, then the terminal can continue to receive the multicast service, but the terminal cannot properly manage the configuration when the serving cell does not support the service
Solution Approach 1:
The terminal performs preliminary detection of whether the serving cell supports the inactive multicast service before maintaining the configuration. By detecting the service support status in advance, the terminal can proactively determine whether to release or suspend the configuration, preventing potential service transmission failures while avoiding unnecessary configuration management overhead.
Solution Approach 2:
The patent introduces dynamic configuration management where the terminal adjusts its behavior based on real-time detection of serving cell support status. The terminal dynamically decides whether to maintain, release, or suspend the inactive multicast service configuration according to the detected support status, enabling adaptive response to changing network conditions.
2Loss of energy
If the terminal releases the inactive multicast service configuration when moving out of the serving cell, then the terminal can save resources, but the terminal may lose the ability to receive the service when returning to the serving cell
Solution Approach 1:
The terminal performs preliminary detection of serving cell support status before releasing the configuration. By detecting whether the serving cell supports the inactive multicast service in advance, the terminal can make informed decisions about when to release or suspend the configuration, ensuring resources are saved without compromising service reception capability when needed.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal continuously monitors the serving cell's support status for the inactive multicast service. Based on this feedback, the terminal dynamically adjusts its configuration management strategy, releasing the configuration when the serving cell does not support the service and maintaining it when the serving cell does support the service, thus balancing resource efficiency with service reliability.
3Ease of operation
If the network device sends configuration indication to manage the inactive multicast service, then the terminal can properly manage the configuration, but the network device complexity increases
Solution Approach 1:
The patent enables the terminal to perform self-service configuration management by detecting the serving cell's support status and autonomously deciding whether to release or suspend the inactive multicast service configuration. This self-service approach eliminates the need for complex network device intervention, simplifying network device operations while maintaining effective terminal-side configuration management.
Solution Approach 2:
The terminal uses feedback from detecting the serving cell's support status to autonomously manage its own configuration. The terminal receives feedback about whether the serving cell supports the inactive multicast service and uses this information to make independent decisions about configuration management, reducing the burden on the network device and simplifying the overall system architecture.

AI summary
A service processing method includes: releasing or suspending, in response to determining that a serving cell does not support an inactive multicast service, a configuration and/or a radio bearer of the inactive multicast service. An indication sending method includes sending a configuration indication to a terminal, wherein the configuration indication is configured to indicate the terminal to release or suspend at least one of a configuration or a radio bearer of an inactive multicast service.
