Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no effective method for performing broadcast reception on a secondary cell (SCell) in wireless communication systems, which hinders efficient resource utilization in mobile communication networks.
Innovation Solution
A communication method and apparatus that enable broadcast reception on an SCell by obtaining and parsing network identifiers associated with the SCell or primary secondary cell group cell (PSCell) to correctly receive broadcast services, optimizing system resource usage by reducing unnecessary communication overheads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If broadcast reception is implemented on SCell, then network resource utilization is improved, but device complexity increases due to additional network identifier parsing requirements
Solution Approach 1:
The patent embeds the network identifier parsing function within the existing broadcast reception process on SCell. The terminal device parses network identifiers from MCCH messages nested within the SCell broadcast channel structure, allowing broadcast reception functionality to be integrated without adding separate independent systems.
Solution Approach 2:
The terminal device autonomously parses network identifiers from received MCCH messages and performs self-matching with stored network identifier lists. This self-service mechanism eliminates the need for network-side assistance or additional control signaling, reducing overall system complexity while enabling broadcast reception on SCell.
2Measurement precision
If network identifier parsing is performed for broadcast service matching, then broadcast service reception accuracy is improved, but data transmission overhead increases
Solution Approach 1:
The patent extracts only the essential network identifier elements from MCCH messages that are needed for service matching. Instead of transmitting or processing complete service descriptor information, the terminal extracts and compares compact network identifier fields, reducing data transmission overhead while maintaining matching accuracy.
Solution Approach 2:
The patent performs partial matching by comparing only network identifiers rather than complete service descriptors. This partial action approach provides sufficient accuracy for broadcast service reception while significantly reducing the amount of data that must be transmitted and processed, as full service detail information is not required for initial service identification.

AI summary
This application provides a communication method, apparatus, and system, and a storage medium. The method includes: obtaining information about a first network identifier corresponding to a first network index; obtaining a first multicast/broadcast service control channel MCCH message; and determining, based on the information about the first network identifier corresponding to the first network index, information about an identifier of a first broadcast service included in the first MCCH message, where both the first network index and the first MCCH message are associated with a secondary cell SCell or a primary secondary cell group cell PSCell. Information about a network identifier corresponding to a network index associated with an SCell or a PSCell is obtained, so that an identifier of a broadcast service that is in an MCCH message of the SCell or the PSCell and that is indicated by the network index can be obtained through parsing based on the information about the network identifier, to perform broadcast service matching. In this way, a terminal device can correctly receive the broadcast service on the SCell or the PSCell.
