Solution Overview

Problem

The increasing complexity of managing diverse radio technologies in telecommunications networks, particularly due to varying user equipment types and mobility states, leads to inefficient use of network resources and cumbersome management mechanisms, especially with the rise of machine-to-machine (M2M) devices and Internet of Things (IoT) applications.

Innovation Solution

A simplified telecommunications network utilizing software-defined network (SDN) principles decouples the routing infrastructure from the switching infrastructure, enabling dynamic management and control based on network and device conditions, allowing for efficient routing and resource allocation across multiple radio access technologies (RATs) like LTE, Wi-Fi, and 5G, using Internet Protocol (IP) for mobility management and policy-based service delivery.

Solution Approach 1:

The patent implements a universal mobility management mechanism that handles multiple UE types (mobile devices, stationary M2M devices, IoT devices) and mobility states through a single unified framework. The network entity uses a common decision-making process based on device conditions, network conditions, and service requirements to select appropriate radio access technologies, eliminating the need for separate management interfaces for each device type while maintaining device-specific management capabilities.

Inventive Principle:

Solution Approach 1:

The patent implements dynamic mobility management by continuously monitoring device conditions (mobility state, device type), network conditions (network load, available radio access technologies), and service requirements. The network entity dynamically adjusts routing decisions and resource allocation in real-time based on changing conditions, optimizing network resource utilization while maintaining device-specific management capabilities. This dynamic approach allows efficient resource sharing across different device types and mobility states.

Inventive Principle:

3Adaptability or versatility

If complex tunneling protocols are used for interfacing radio technologies, then compatibility between different radio technologies is achieved, but management and control becomes cumbersome

Engineering Contradiction:

Solution Approach 1:

The patent introduces a network entity as an intermediary that mediates between different radio access technologies and various device types. This network entity implements a unified mobility management function that translates and coordinates between different radio technology interfaces, enabling compatibility without exposing complex tunneling protocols to the management layer. The intermediary simplifies management by providing a standardized interface while maintaining the flexibility to handle multiple radio technologies.

Solution Approach 1:

The patent applies parameter changes by adapting the mobility management approach based on device conditions, specifically detecting whether a device is stationary or mobile. For stationary M2M devices, the system changes the routing parameters to select more efficient radio access technologies (such as direct IP connectivity or alternative M2M-specific interfaces) instead of forcing LTE with GTP tunneling. This parameter adaptation maintains network coverage reliability while significantly improving network resource efficiency for stationary devices.

Inventive Principle:
Principle #35Parameter changes

AI summary

Mobility management may be utilized to effectuate handover and route packets of information to one or more radio access technologies and/or cells/access points based on network, UE conditions, device location, and/or network entity location. Packet routes, device addresses, handover functions, dynamically may be adjusted based on the best radio technology, cell layer, service provider specified criteria, or the like.
