Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies restrict terminals from receiving multicast services in non-connected states, limiting their functionality and efficiency.
Innovation Solution
The method involves determining multicast broadcast service control channel configuration using broadcast messages and dedicated signaling, enabling terminals to receive multicast service configurations even in non-connected states, with mechanisms to ensure only authorized terminals can access the service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the terminal is switched to a non-connected state when there is no multicast service data, then energy consumption is reduced, but the terminal cannot receive multicast service configuration
Solution Approach 1:
The patent segments the control channel into two parts: a broadcast portion that carries configuration information accessible in non-connected state, and a dedicated portion for connected state operations. This allows the terminal to obtain essential configuration without needing to maintain connected state, thus reducing energy consumption while preserving service reception capability.
Solution Approach 2:
The network device performs preliminary action by broadcasting the multicast service control channel configuration information before the terminal needs to receive actual multicast data. This allows the terminal to acquire configuration in advance during non-connected state, so when data arrives, the terminal can quickly switch to connected state with all necessary configuration already in place.
2Reliability
If the terminal remains in connected state to receive multicast service, then service reception is ensured, but energy consumption increases
Solution Approach 1:
The patent extracts the essential configuration information delivery function from the connected state dependency. By broadcasting control channel configuration through broadcast messages, the system separates configuration delivery from data transmission, allowing terminals to obtain configuration without maintaining connected state, thus reducing energy consumption while ensuring service reception capability.
3Ease of operation
If broadcast message is used to transmit configuration information, then terminals in non-connected state can access it, but security control becomes difficult
Solution Approach 1:
The patent applies local quality by differentiating the treatment of different configuration information elements. Sensitive configuration information is protected through dedicated signaling with security control, while non-sensitive control channel configuration is broadcast for wide accessibility. This allows terminals in non-connected state to access necessary configuration while maintaining security control over sensitive data through selective broadcasting and dedicated signaling mechanisms.

AI summary
The present disclosure relates to the technical field of communications, and in particular to a configuration information receiving method, a configuration information sending method, a system, a communication apparatus, and a storage medium. The configuration information receiving method comprises: determining configuration information of a multicast broadcast service control channel according to a broadcast message and/or dedicated signaling sent by a network device, wherein the multicast broadcast service control channel is used for transmitting a multicast broadcast service configuration. According to the present disclosure, it can be ensured that a terminal in a non-connected state can also successfully obtain a multicast service configuration and then successfully receive a multicast service according to the multicast service configuration in the non-connected state. It can be ensured that only a specific terminal can obtain a multicast service configuration and then successfully receive a multicast service according to the multicast service configuration in a non-connected state.
