Solution Overview

Problem

Existing wireless communication devices equipped with multiple SIMs struggle to simultaneously receive paging messages from multiple networks due to the lack of a comprehensive mechanism for handling paging information across different communication carriers.

Innovation Solution

A wireless communication device is designed to transmit registration requests to management devices of multiple PLMNs, allowing it to receive paging messages from both its primary and secondary networks through a shared communication framework, enabling simultaneous connection and monitoring of paging across multiple networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a UE includes only one transmission and reception unit, then the device complexity is reduced, but the UE cannot simultaneously connect with networks of different communication carriers

Engineering Contradiction:

Improvetransmission and reception unitVSAvoidsimultaneous connection capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent merges the paging reception capabilities for multiple PLMNs into a single transmission and reception unit. The UE registers with multiple PLMNs and receives paging messages for all registered PLMNs through one communication interface, eliminating the need for separate transmission and reception units for each network.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single transmission and reception unit is designed to handle multiple functions: it can communicate with multiple different PLMNs, transmit registration requests to multiple management devices, and receive paging messages from multiple networks. This multi-functional design replaces the need for dedicated units for each network.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If the UE shares paging information between multiple networks, then the paging reception capability is improved, but the device complexity increases due to multiple transmission and reception units

Engineering Contradiction:

Improvepaging reception capabilityVSAvoidtransmission and reception unit

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines paging information reception from multiple PLMNs into a single transmission and reception unit. The UE maintains registration with multiple PLMNs and receives their paging messages through one communication interface, avoiding the complexity of multiple separate units while ensuring reliable paging reception.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single transmission and reception unit acts as an intermediary that handles communication with multiple PLMNs. It manages registration requests to multiple management devices and receives paging messages from different networks, mediating between the UE and multiple network infrastructures without requiring separate communication units for each.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If the UE connects with one network at a time, then the device complexity is reduced, but the UE cannot receive paging from other networks

Engineering Contradiction:

Improvenetwork connection managementVSAvoidpaging information

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The patent merges paging information reception from multiple PLMNs into a single network connection framework. The UE registers with multiple PLMNs simultaneously and receives their paging messages through one active connection, eliminating the need to switch between networks while preventing loss of paging information from any registered PLMN.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single network connection is designed with multi-functional capability to handle communication with multiple PLMNs. It can transmit registration requests to multiple management devices and receive paging messages from different networks through the same connection interface, ensuring no paging information is lost while maintaining simple device architecture.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A wireless communication device (100) according to the present disclosure includes a controller (140). The controller (140) transmits a registration request message to a first management device (10A) that belongs to a first PLMN and that manages registration of a wireless communication device (100). The registration request message includes second PLMN_ID information. The second PLMN_ID information is also included in the first PLMN list information that is stored in the second subscriber identity module and that is stored in the first subscriber identity module. The controller (140) receives, from a first base station (200A) that belongs to the first PLMN, a first paging message related to a first paging that has been generated in the first PLMN. The controller (140) receives, from the first base station (200A), a second paging message related to a second paging that has been generated in a second PLMN.
