Solution Overview

Problem

In the Internet of Things, a large number of terminals frequently accessing a network leads to increased network load and decreased Quality of Service (QoS) due to multiple signaling interactions, resulting in a 'signaling storm'.

Innovation Solution

A method and device that control terminal access by setting up a public bearer for terminals with a classification identifier, determining if the access request time falls within a predetermined time window, and notifying the terminal to access the network through this bearer, thereby reducing redundant signaling interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If terminals perform multiple uplink and downlink signaling interactions to access the network, then reliable network access is achieved, but network load increases and QoS deteriorates due to signaling storms

Engineering Contradiction:
Improvenetwork access reliabilityVSAvoidnetwork access efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent merges multiple individual terminal access procedures into a single group-based access procedure. Terminals with the same service type are grouped together and can access the network through one representative terminal's signaling interaction, eliminating redundant signaling for each individual terminal while maintaining reliable network access for all group members.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal access mechanism where a single access procedure serves multiple terminals simultaneously. The group-based access allows one signaling sequence to establish network access for an entire group of terminals sharing the same service type, making the access procedure multi-functional rather than dedicated to single terminals.

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

2Adaptability or versatility

If each terminal performs individual signaling interactions for network access, then terminal-specific network access is ensured, but a signaling storm occurs when massive terminals access frequently

Engineering Contradiction:
Improveterminal access flexibilityVSAvoidsignaling storm
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent merges multiple individual terminal access procedures into a single group-based access procedure. Terminals with the same service type are grouped together and can access the network through one representative terminal's signaling interaction, eliminating redundant signaling for each individual terminal while maintaining reliable network access for all group members.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent uses a representative terminal as a copy or proxy for the entire group of terminals. The signaling interactions performed by one terminal are effectively copied or replicated to establish access for all terminals in the group, avoiding the need for each terminal to perform identical signaling sequences independently.

Inventive Principle:
Principle #26Copying

3Reliability

If multiple signaling interactions are performed for network access, then proper network authentication and setup are completed, but network load increases

Engineering Contradiction:
Improvenetwork authentication reliabilityVSAvoidsignaling volume
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent merges multiple individual terminal access procedures into a single group-based access procedure. Terminals with the same service type are grouped together and can access the network through one representative terminal's signaling interaction, eliminating redundant signaling for each individual terminal while maintaining reliable network access for all group members.

Inventive Principle:

AI summary

The present invention discloses a method, device, terminal, and system for controlling access of multiple terminals, and belongs to the field of communications. The method includes: receiving an access request, where the access request carries a classification identifier (101); setting up a public bearer for a terminal belonging to the classification identifier (102); and notifying the terminal belonging to the classification identifier, so that the terminal belonging to the classification identifier accesses a network through the public bearer (103). The terminal includes a third sending module, a second receiving module, and an access module. The system includes a network element at an access side and a terminal. In the present invention, a signaling storm can be avoided, a load of a network can be reduced, and QoS quality of service can be improved.
