Solution Overview

Problem

Existing communication systems limit multicast services to connected states, restricting their availability and causing potential errors when terminals receive paging messages in non-connected states.

Innovation Solution

A method and apparatus for terminals and network devices to handle multicast service operations, including receiving and sending paging messages with MBS information, and performing or indicating operations such as receiving MCCH messages, establishing RRC connections, or ignoring the message, based on specific conditions and indications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the terminal receives multicast service only in connected state, then the network device can control the terminal properly, but the multicast service availability is limited and cannot serve terminals in non-connected state

Engineering Contradiction:
Improvemulticast service availabilityVSAvoidoperation control complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the terminal's operation dynamic by allowing it to adapt its behavior based on the paging message content and service configuration. The terminal can dynamically choose between receiving MCCH messages, establishing RRC connection, or ignoring the paging message, thereby achieving versatility across different states while maintaining manageable complexity through standardized decision logic.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of the terminal based on received paging messages. By modifying the terminal's state and behavior parameters according to specific message contents and service configurations, the system enables multicast service in both connected and non-connected states without overwhelming complexity.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the terminal operates in non-connected state for multicast service, then service availability improves, but the terminal may perform operations in error after receiving paging message

Engineering Contradiction:
Improveservice state flexibilityVSAvoidoperation accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements feedback mechanisms where the terminal receives paging messages containing service information and configuration parameters, processes this feedback, and adjusts its operations accordingly. This feedback loop ensures the terminal performs correct operations in non-connected state by baseing decisions on received information rather than default behaviors.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent prepares the terminal in advance by providing service configuration information through paging messages before the terminal needs to perform operations. This preliminary action of delivering service information and parameters ensures the terminal is properly configured to execute operations accurately without errors.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the terminal establishes RRC connection frequently to receive multicast service, then service reliability improves, but energy consumption and network overhead increase

Engineering Contradiction:
Improveservice delivery reliabilityVSAvoidterminal energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by allowing the terminal to receive multicast service in non-connected state without establishing full RRC connection. The terminal performs only the necessary partial operations (receiving paging messages, interpreting service information) rather than completing full connection establishment, thereby reducing energy consumption while maintaining sufficient service reliability.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent makes the paging message universal by enabling it to carry both service information and configuration parameters that allow the terminal to operate in multiple modes (connected and non-connected). This multi-functionality reduces the need for frequent RRC connections while maintaining service reliability across different operational states.

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

AI summary

The present disclosure relates to the technical field of communications, and specifically relates to an operation execution method and apparatus, an operation instruction method and apparatus, a communication apparatus, and a storage medium. The operation execution method comprises: receiving a paging message, wherein the paging message includes multicast broadcast service information; and executing a first operation, wherein the first operation comprises at least one of the following: receiving a multicast broadcast service control channel (MCCH) message, triggering establishment of a radio resource control (RRC) connection, and ignoring the paging message. In the present disclosure, after receiving a paging message carrying multicast broadcast service information, a terminal can select one or more first operations from among three first operations and execute same, such that operations which are executed by the terminal after the terminal receives the paging message are regulated, helping in avoiding disorder of the execution of operations executed by the terminal after the terminal receives the paging message.
