Solution Overview

Problem

The deployment of a large number of Machine-Type Communications (MTC) devices in wireless networks negatively impacts Human-to-Human (H2H) services due to limited wireless resources, causing access or service implementation limitations for H2H devices.

Innovation Solution

A service control method that includes receiving device type indication information for User Equipment (UE) in service request messages, allowing network elements to determine whether the UE is an MTC device and adjust service operations based on current load thresholds, thereby controlling MTC service implementation to reduce its impact on H2H services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a large quantity of MTC devices are deployed in the wireless network, then the coverage and application scope of MTC services are improved, but the wireless resources become limited and H2H service access is restricted

Engineering Contradiction:
Improvequantity of MTC devicesVSAvoidH2H service access
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent segments MTC devices into different groups based on their service requirements and resource consumption patterns. By classifying MTC devices into categories such as those requiring frequent access, those with large data volumes, and those with specific QoS requirements, the network can apply differentiated service control policies to each group, thereby managing resource allocation more effectively while preserving H2H service access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes key parameters such as access thresholds, service request permissions, and resource allocation limits based on network load conditions and device types. When network resources are sufficient, more MTC devices are permitted to access; when resources become constrained, access thresholds are raised or certain MTC services are restricted, thereby dynamically balancing MTC deployment with H2H service quality.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If MTC devices are served with the same service processing logic as H2H devices, then service consistency is maintained, but wireless resources are overwhelmed and H2H service implementation is limited

Engineering Contradiction:
Improveservice processing consistencyVSAvoidservice implementation capacity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies local quality by implementing different service processing logic for different device types within the same network. MTC devices receive customized service handling based on their specific characteristics and requirements, while H2H devices continue to receive standard service processing. This allows the network to optimize resource allocation for each device category, preventing MTC devices from overwhelming shared resources while maintaining appropriate service consistency where needed.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces dynamic service processing that adapts to real-time network conditions and device types. Service processing logic is not static but adjusts based on current network load, device capability, and service priority. This dynamic approach enables the network to handle MTC and H2H services differently when necessary, optimizing overall service implementation capacity while maintaining flexibility.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If device type indication information is added to service request messages, then differentiated service control is enabled, but message complexity and processing overhead increase

Engineering Contradiction:
Improvedifferentiated service control capabilityVSAvoidmessage structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal device type indication mechanism that can identify and differentiate multiple MTC device categories using a standardized field in service request messages. This single indication field serves multiple purposes: identifying device type, determining service priority, and triggering appropriate service processing logic. By using a multi-functional indication mechanism rather than separate fields for each attribute, the patent minimizes message complexity while enabling comprehensive differentiated service control.

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

AI summary

A service control method for a machine type communications (MTC) device and a related apparatus, where the method includes receiving, by an access-network network element, a paging request message from a core-network network element, wherein the paging request message carries device type indication information of a paged user equipment (UE), determining a device type of the UE according to the device type indication information of the UE, and paging the UE using a dedicated paging resource allocated to an MTC device when the UE is the MTC device.
