Service-Specific Paging Matching for Terminal Response Decisions

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing 3GPP paging procedure lacks a mechanism to set a matching value related to a service, leading to inefficiencies in determining whether a terminal device should respond to a paging message.

Innovation Solution

A service indication method that involves sending or receiving matching information specific to a user, which includes one or more matching values corresponding to one or more services or service types, allowing the terminal device to determine whether to respond to a paging message based on service-specific criteria.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a paging message carries a matching value not related to a service, then the paging procedure can be completed, but the terminal device cannot make informed decisions on whether to respond based on service priorities

Engineering Contradiction:

Improveservice-specific paging response capabilityVSAvoidservice priority information

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The matching value is segmented to include service-specific identifiers that allow the terminal device to distinguish between different service types. This segmentation enables the terminal to match the paging message against stored service information and make informed response decisions based on service priorities.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A service indication field acts as an intermediary between the network and terminal device, carrying service-specific matching information. This intermediary enables the transmission of service priority information without disrupting the existing paging message structure, allowing the terminal to make informed response decisions.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the paging message includes service-specific matching information, then the terminal device can make informed decisions on responding, but the paging message structure becomes more complex

Engineering Contradiction:

Improvepaging response decision-makingVSAvoidpaging message structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The service indication field is designed to be multi-functional, serving both as a service identifier and a priority indicator. This universal field enables the terminal device to make informed paging response decisions without requiring multiple separate fields, thereby limiting the increase in message structure complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The existing matching value parameter in the paging message is enhanced to include service-specific information. By modifying the parameters within the existing message structure rather than adding new message fields, the complexity increase is minimized while still enabling informed terminal device decisions.

Inventive Principle:

Principle #35Parameter changes

AI summary

Embodiments of this disclosure provide a service indication method and a device to resolve a problem that a matching value related to a service cannot be set in the related art. The method is executed by a network function and includes: receiving matching information specific to a user, or sending the matching information specific to the user to a terminal device of the user, where the matching information includes one or more matching values, and one of the matching values corresponds to one or more services or corresponds to one or more service types.
