Solution Overview

Problem

Existing 5G mobile communication systems face challenges in efficiently managing UE registration and data transfer, particularly in supporting paging early indication and subgrouping assistance, which can lead to inefficiencies in resource allocation and user equipment performance.

Innovation Solution

A method and user equipment (UE) are developed to support paging early indication with paging subgrouping assistance (PEIPS) by inserting capability and probability information into registration request messages, enabling the UE to receive assistance information including a paging subgroup identifier, thereby optimizing registration procedures and resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If paging early indication with paging subgrouping assistance is implemented, then resource allocation efficiency is improved, but device complexity increases

Engineering Contradiction:

Improveresource allocation efficiencyVSAvoidUE registration procedure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the UE capability information into distinct fields within the registration request message, including a paging subgrouping capability indication and requested PEIPS assistance information. This segmentation allows the network to process and allocate resources more efficiently by receiving structured capability data, while the UE maintains manageable complexity through standardized message formatting.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary action by having the UE indicate its PEIPS capability and provide requested assistance information during the registration procedure before actual paging operations occur. This advance capability declaration and information exchange enables the network to optimize resource allocation in advance, improving efficiency without increasing operational complexity during actual communication.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If PEIPS assistance information is inserted into registration request messages, then data transfer efficiency is improved, but message processing complexity increases

Engineering Contradiction:

Improvedata transfer efficiencyVSAvoidmessage processing complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent makes the registration request message multi-functional by incorporating PEIPS capability indications and requested assistance information into the existing universal registration procedure. This allows the same message structure to serve both traditional registration purposes and PEIPS setup, enabling efficient data transfer without requiring separate dedicated message processing flows.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent modifies the registration request message by adding new parameters such as paging subgrouping capability indication and requested PEIPS assistance information. These parameter changes enable enhanced data transfer efficiency through optimized resource allocation while maintaining compatibility with existing message processing frameworks, thus not significantly increasing processing complexity.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If paging subgrouping capability indication is provided, then system efficiency is improved, but registration procedure time increases

Engineering Contradiction:

Improvesystem efficiencyVSAvoidregistration procedure time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent merges the PEIPS capability indication and requested assistance information into the existing registration request message. By combining these new PEIPS-related elements with the standard registration procedure, the system achieves improved efficiency through integrated processing, while avoiding the time penalty that would result from separate capability negotiation steps.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent ensures continuity of useful action by incorporating PEIPS capability exchange within the ongoing registration procedure rather than adding it as a separate sequential step. The capability indication and assistance information are processed continuously alongside other registration parameters, maintaining system efficiency while minimizing additional registration procedure time.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

According to one embodiment of this specification, there is provided a method performed by a user equipment (UE). The method may comprise: if the UE supports paging early indication with paging subgrouping assistance (PEIPS) assistance information, inserting a paging subgrouping capability indication which indicates UE's capability to support PEIPS assistance information into a registration request message; if the PEIPS assistance information is supported, inserting UE's paging probability information in a requested PEIPS assistance information of the registration request message; transmitting the registration request message; and receiving a first message including the PEIPS assistance information. The PEIPS assistance information may include a paging subgroup identifier (ID). A non-access stratum (NAS) layer of the UE may indicate the PEIPS assistance information to a lower layer.
