Solution Overview

Problem

User equipment in a wait or extended wait period currently responds inconsistently to paging requests, leading to issues where lower priority devices may be more reactive than higher priority devices, and the network lacks control over which requests are responded to during these times.

Innovation Solution

User equipment is configured to respond to paging requests during a wait or extended wait time based on paging information received from the network, which indicates which requests should be responded to and which can be ignored, allowing the network to manage the response dynamically according to loading conditions and request priority.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If user equipment does not respond to paging requests during wait time, then network load is reduced, but higher priority requests cannot be distinguished from lower priority requests

Engineering Contradiction:
Improvenetwork loadVSAvoidpriority handling
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent applies local quality by differentiating the response behavior to different types of paging requests based on their priority. User equipment is configured to respond to high priority paging requests (such as voice calls) while ignoring low priority requests (such as data sessions) during wait time. This selective response strategy reduces overall network load while ensuring that critical high priority communications are not missed, thereby resolving the contradiction between reducing network load and maintaining reliable priority handling.

Inventive Principle:
Principle #3Local quality

2Reliability

If user equipment responds to all paging requests during wait time, then no important requests are missed, but network load increases and wait time management is compromised

Engineering Contradiction:
Improverequest responseVSAvoidnetwork load
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements dynamics by making the user equipment's response behavior adaptive rather than static. The UE dynamically adjusts its paging response strategy based on the priority indicator contained in each paging request. High priority requests trigger a response even during wait time, while low priority requests are ignored. This dynamic approach allows the system to maintain reliable response for important communications while minimizing network load by not responding to less critical requests.

Inventive Principle:
Principle #15Dynamics

3Loss of energy

If user equipment ignores all paging requests during wait time, then network load is minimized, but the network loses control over which requests should be responded to

Engineering Contradiction:
Improvenetwork loadVSAvoidnetwork control
Core Design Contradiction:
Loss of energyVSAdaptability or versatility

Solution Approach 1:

The patent applies feedback by introducing a mechanism where the network sends priority indicators with paging requests, and the user equipment uses this feedback information to determine whether to respond. The priority indicator acts as feedback from the network about the importance of each paging request, enabling the UE to make informed decisions about response behavior. This maintains network control over which requests should be responded to while minimizing unnecessary network load from responding to low priority requests during wait time.

Inventive Principle:
Principle #23Feedback
