Multi-Card Terminal Notification Timing for Network Switching

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Multi-card terminals waste network resources by leaving or returning to networks without proper notification, leading to unnecessary scheduling and paging.

Innovation Solution

Implement a method for determining conditions to send or skip sending notification messages, using a first condition that includes a notification message reporting condition or a first timer to prohibit message sending, thereby reducing unnecessary network interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the terminal sends notification messages every time it leaves or returns to a network, then the network can accurately track terminal status, but network resources are wasted due to unnecessary scheduling and paging

Engineering Contradiction:

Improvenetwork tracking accuracyVSAvoidnetwork resource waste

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent introduces a timer parameter to control notification message sending. The terminal compares the time interval since the last notification against a threshold to determine whether to send a notification. This parameter-based control reduces unnecessary notifications while ensuring important status changes are communicated, thus balancing network tracking accuracy with resource conservation.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the terminal frequently switches between networks, then the terminal can access different network services, but signaling overhead increases due to repeated notification messages

Engineering Contradiction:

Improvenetwork switching capabilityVSAvoidsignaling overhead

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent implements periodic action by using a timer to control notification message sending at regular intervals or based on time thresholds. Instead of sending notifications on every network switch event, the terminal uses time-based periodic control to reduce the frequency of signaling messages while maintaining network awareness of terminal status changes.

Inventive Principle:

Principle #19Periodic action

3Speed

If the terminal sends notification messages without time-based control, then network status updates are timely, but signaling overload occurs during frequent network switching

Engineering Contradiction:

Improvestatus update timelinessVSAvoidsignaling overload

Core Design Contradiction:

SpeedVSObject-generated harmful factors

Solution Approach 1:

The patent applies preliminary action by pre-configuring a timer threshold before network switching occurs. The terminal evaluates whether the time interval meets the threshold condition before sending a notification message. This preliminary time-based evaluation prevents unnecessary signaling overload while ensuring that status updates are sent timely when appropriate conditions are met.

Inventive Principle:

Principle #10Preliminary action

AI summary

A message notification method, a terminal, and a network device are provided. The message notification method includes: determining whether a first condition is met; and sending a notification message to a first network when the first condition is met, or skipping sending a notification message to a first network when the first condition is not met. The first condition includes any one of the following: a notification message reporting condition; and a first timer expires or is not running, where the first timer is used to prohibit a terminal from sending the notification message.
