IoT Server Coordination for Cross-PLMN UE Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack mechanisms for efficiently transferring user equipment (UEs) between Public Land Mobile Networks (PLMNs) for reasons other than coverage, such as congestion or optimization, and do not fully leverage the capabilities of IoT servers in managing network context and visibility across multiple PLMNs.
Innovation Solution
Implementing methods for PLMN transfer facilitated by IoT servers, which utilize UE context information and network analytics to manage UE transfers between PLMNs for congestion or optimization, including manual network selection and core network-driven reselection processes.

Engineering Contradiction Analysis
1Productivity
If UEs are transferred between PLMNs for congestion or optimization reasons, then network usage efficiency is improved, but existing technologies lack the mechanisms to enable such transfers
Solution Approach 1:
The patent introduces an IoT server as an intermediary entity that facilitates PLMN transfers between UEs and multiple PLMNs. The server maintains context information about UEs and networks, receives transfer requests from PLMNs, and coordinates the transfer process. This intermediary approach enables complex transfer operations without requiring direct complex interactions between UEs and multiple PLMNs, thus improving network usage efficiency while managing complexity through centralized coordination.
Solution Approach 2:
The IoT server is designed with multi-functionality, serving as a central coordination point for multiple PLMNs and managing various aspects of UE transfers including context maintenance, transfer request processing, and network selection. This universal approach allows the same server infrastructure to handle transfers across different PLMNs and for different reasons (congestion, optimization), improving overall system efficiency without requiring separate mechanisms for each scenario.
2Reliability
If IoT servers leverage UE context information and network analytics, then informed decision-making on UE transfers is improved, but full utilization of server capabilities is not achieved in existing technologies
Solution Approach 1:
The patent implements feedback mechanisms where the IoT server continuously receives and processes network analytics and UE context information from multiple PLMNs. The server uses this feedback to make informed decisions about UE transfers, adjusting its behavior based on current network conditions, UE performance metrics, and congestion levels. This feedback-driven approach ensures reliable decision-making while fully utilizing the server's analytical capabilities across different network scenarios.
Solution Approach 2:
The IoT server performs preliminary actions by maintaining UE context information and network analytics in advance of transfer decisions. The server pre-processes network conditions, UE capabilities, and performance metrics so that when transfer requests occur, decisions can be made quickly and reliably based on pre-analyzed data. This preliminary preparation enables the server to fully leverage its analytical capabilities rather than reacting to transfer requests without context.

AI summary
Radio networks such as Public Land Mobile Networks (PLMNs), user equipment devices (UEs), servers such as Internet-of-Things servers, and core network entities may be adapted to facilitate transfers of connections of wireless devices. For example, a first PLMN may provide restricted access to a UE to assist the UE in finding a second PLMN for a full connection. Entities may be adapted to support for non-coverage related PLMN transfers, such as transfers initiated by UEs, PLMNs, servers, and core network entities, e.g., in response to changing usage, congestion, etc.
