Service Indication with Service-Specific Paging Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 3GPP paging procedure lacks the ability to set a matching value related to a service, leading to inefficiencies in communication effectiveness and flexibility.
Innovation Solution
A service indication method that involves a network function and terminal device exchanging matching information, including values corresponding to specific services or service types, allowing the terminal device to determine whether to respond to paging messages based on these values.
Engineering Contradictions & Design Principles
Engineering 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 communication effectiveness and flexibility are reduced
Solution Approach 1:
The matching value is segmented into service-specific matching values, where each matching value corresponds to a specific service or service type. This allows the terminal device to identify and respond to paging messages relevant to active services, improving communication effectiveness by filtering out irrelevant paging messages.
Solution Approach 2:
The network function acts as an intermediary that generates and provides service-specific matching values to the terminal device. This intermediary ensures that the terminal device receives accurate service-related information for making informed decisions about responding to paging messages, thereby reducing information loss.
2Adaptability or versatility
If the terminal device always responds to paging messages, then connection can be established, but communication flexibility is reduced
Solution Approach 1:
The terminal device dynamically decides whether to respond to a paging message based on comparing the received service-specific matching value with locally stored matching values associated with active services. This dynamic response mechanism provides communication flexibility by allowing the terminal to selectively respond only when relevant, avoiding unnecessary energy consumption from always responding.
3Measurement precision
If matching information is exchanged between network function and terminal device, then service-specific matching is enabled, but device complexity increases
Solution Approach 1:
The matching information exchange mechanism is designed to be universal and multi-functional, serving multiple purposes: identifying services, determining response decisions, and enabling flexible communication. By creating a versatile framework that handles various service types through a common matching value structure, the system achieves high matching precision without proportionally increasing complexity.

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.
