Solution Overview

Problem

Current mobile communication networks are optimized for human-type communication and face challenges in efficiently supporting machine-type communication, leading to network congestion when attempting to contact a large number of terminals simultaneously.

Innovation Solution

A method involving a single paging operation that uses a group identifier to jointly page multiple terminals, allowing for the inclusion of additional information such as response time thresholds and specific commands, thereby reducing network load and congestion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If individual paging operations are used to contact each terminal separately, then each terminal can be reached reliably, but network signaling load increases significantly and congestion occurs

Engineering Contradiction:
Improveterminal reachabilityVSAvoidnetwork signaling load
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent combines multiple individual paging operations into a single group paging operation. Terminals are organized into groups identified by group identities, allowing a single paging message to address multiple terminals simultaneously. This merging approach maintains reliable terminal reachability while significantly reducing the quantity of paging messages required, thereby decreasing network signaling load and preventing congestion.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal paging mechanism that can serve both individual terminals and groups of terminals through a common group paging identity. The group paging identity acts as a multi-functional identifier that enables a single paging message to reach multiple terminals that share the same group identity, providing a universal solution for both individual and group communication needs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Quantity of substance

If group paging with single paging operation is used, then network signaling load is reduced, but individual terminal identification and specific command delivery becomes more complex

Engineering Contradiction:
Improvenetwork signaling loadVSAvoidgroup management complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent segments terminals into distinct groups based on their group identities, creating a hierarchical structure where terminals are organized by shared characteristics or service requirements. This segmentation allows the network to manage groups as discrete units while maintaining the ability to address individual terminals within groups when necessary, reducing overall management complexity through structured organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The group identity serves as an intermediary between the network and individual terminals. Instead of the network directly managing each terminal individually, the group identity acts as a mediator that enables bulk operations on grouped terminals while still allowing individual terminal identification when needed. This intermediary layer simplifies network management by providing an intermediate level of abstraction.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention relates to the field of paging terminals within a communication network. In order to contact a group of terminals, a common group identification is allocated to each of the terminals within said group. Thereafter, a paging message is created comprising said common group identification. The paging message is then transmitted to all terminals within said group by a single paging operation.
