Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multicast service is applied to NR system, then service discovery capability is improved, but power consumption and signaling overheads increase
Solution Approach 1:
The network device sends multicast area configuration information to the terminal in advance, including area parameter information such as tracking area codes or cell identifiers. This preliminary configuration allows the terminal to pre-determine whether it is located in the service area by comparing with its current location information, thereby avoiding unnecessary power-consuming multicast service detection procedures when not in the service area.
2Measurement precision
If multicast service area determination is performed, then service reception accuracy is improved, but signaling overheads increase
Solution Approach 1:
The patent extracts only the essential area parameter information (such as tracking area codes or cell identifiers) from the complete network configuration and transmits only these critical parameters to the terminal. This extraction approach enables accurate service area determination while minimizing signaling overheads by excluding unnecessary configuration details.
Solution Approach 2:
The terminal autonomously performs service area determination by comparing the received area parameter information with its current location information. This self-service mechanism eliminates the need for continuous network signaling to verify service area status, thereby reducing signaling overheads while maintaining determination accuracy.

AI summary
The present invention provides a multicast service processing method, a multicast service configuration method, and a communications device. The multicast service processing method includes: receiving a multicast area configuration sent by a network device, where the multicast area configuration includes area parameter information of a multicast service; obtaining wireless area information in a case that the multicast area configuration sent by the network device has been received; and determining, based on the area parameter information and the wireless area information, whether the terminal is located in a service area of the multicast service.
