Solution Overview

Problem

There is no effective method for performing broadcast reception on a secondary cell (SCell) in wireless communication systems, particularly in 3GPP networks, which hinders efficient resource utilization and network sharing.

Innovation Solution

A communication method and apparatus that enable a communication apparatus to obtain and parse network identifiers associated with SCells or PSCells to correctly receive broadcast services by obtaining and sending relevant information through dedicated signaling, system information blocks, and multicast/broadcast service control channels, optimizing resource usage and reducing overheads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If broadcast reception is implemented on SCell, then resource utilization is improved, but the complexity of obtaining and parsing network identifiers increases

Engineering Contradiction:
Improveresource utilizationVSAvoidcomplexity of obtaining and parsing network identifiers
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The network side pre-configures and sends network identifier information associated with SCell through system information blocks before the terminal needs to receive broadcast services. This preliminary provision of identification information eliminates the need for complex real-time parsing operations during broadcast reception.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

System information blocks serve as an intermediary mechanism that carries network identifier information between the network and terminal. This intermediary structure simplifies the terminal's task by providing pre-processed identification data rather than requiring the terminal to parse complex network configurations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If network identifier information is sent through dedicated signaling, then broadcast service reception accuracy is improved, but communication overhead increases

Engineering Contradiction:
Improvebroadcast service reception accuracyVSAvoidcommunication overhead
Core Design Contradiction:
Measurement precisionVSLoss of substance

Solution Approach 1:

System information blocks serve multiple functions: they carry network identifier information, provide cell configuration data, and enable broadcast service reception. By making the information carrier universal, the patent avoids the need for separate dedicated signaling channels, thereby reducing overall communication overhead while maintaining accuracy.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges network identifier information with existing system information block structures rather than using separate dedicated signaling. This combining approach reduces communication overhead by transmitting multiple types of information through a single efficient channel mechanism.

Inventive Principle:
Principle #5Merging (Combining)

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), 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.
