Multicast Configuration Updates Without Duplicate Message Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices in connected mode face unnecessary power consumption due to repeated receipt of configuration update information for multicast services, as they may receive configuration updates via both common and dedicated messages, even when only one is necessary.
Innovation Solution
Implement a method where terminal devices in connected mode determine the appropriate manner for obtaining configuration update information based on indication from the access network, choosing between receiving a common message or a dedicated message to avoid duplication and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device uses both common message and dedicated message to obtain configuration update information, then the configuration update information can be obtained, but unnecessary receiving behavior occurs and power consumption increases
Solution Approach 1:
The patent applies dynamics by making the message reception mode adjustable and switchable. The network device can dynamically indicate whether to use common message or dedicated message for configuration updates, and the terminal device adapts its reception behavior accordingly. This dynamic adjustment eliminates unnecessary receiving operations while ensuring reliable configuration updates, directly resolving the contradiction between reliability and power consumption.
2Reliability
If the terminal device monitors both common message and dedicated message for configuration updates, then configuration updates are received, but unnecessary receiving behavior is performed
Solution Approach 1:
The patent implements a dynamic reception mode where the terminal device switches between monitoring common message and dedicated message based on network indication. This dynamic approach ensures that the terminal only monitors the relevant message type for configuration updates, eliminating redundant monitoring operations while maintaining reliable configuration update acquisition, thus improving receiving efficiency without sacrificing reliability.
3Reliability
If the terminal device receives configuration update information through both common and dedicated messages, then configuration updates are obtained, but the system complexity increases
Solution Approach 1:
The patent reduces system complexity by implementing a dynamic selection mechanism where only one message type (common or dedicated) is used for configuration updates at any given time, as indicated by the network. This eliminates the need for the terminal device to continuously process both message types, simplifying the message processing logic while ensuring reliable configuration updates are received through the appropriate channel.
Data Source
AI summary
A communication method includes obtaining, by a terminal device or a chip in the terminal device, configuration information of a multicast service. The configuration information is useable by the terminal device to receive data of the multicast service. The method further includes receiving first indication information from an access network device. The first indication information is useable to indicate a manner of obtaining configuration update information of the multicast service by the terminal device. The manner of obtaining the configuration update information of the multicast service is a first manner or a second manner. The first manner is obtaining the configuration update information by receiving a common message. The second manner is obtaining the configuration update information by receiving a dedicated message.
