Multi-channel Communication Terminal Remote Identity Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication terminals are limited to accessing a single service provider and network based on a physical SIM card, restricting their ability to use services from different providers or networks.
Innovation Solution
A multi-channel communication terminal with two communication modules and a management unit that dynamically loads subscriber identity information from a remote server, allowing it to establish and share communication channels across various service providers and networks, including GSM, GPRS, LTE, and WiFi, using SIM cards and local area network interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication terminal uses a physical SIM card to access a service provider, then it can establish a stable connection with that provider, but it is limited to accessing only that single service provider and cannot access other networks or providers
Solution Approach 1:
The communication terminal is designed with multi-functionality to support both traditional SIM card-based access and remote server-based authentication. The terminal can function as a conventional device when a SIM card is inserted, or as a remote-access device when connecting to the service provider network without a SIM card, thereby accessing multiple service providers through a single device
Solution Approach 2:
The service provider network acts as an intermediary that provides authentication and access control. The terminal communicates with the network through multiple channels (SIM card interface and remote server interface), allowing the network to mediate access rights and enable versatile connectivity without requiring multiple physical SIM cards
2Adaptability or versatility
If a communication terminal supports multiple communication modes and devices, then it can access different networks, but each device can only access its corresponding service provider and cannot share services across devices
Solution Approach 1:
The terminal incorporates universal access capability by supporting multiple communication modes (2G, 3G, 4G, WiFi, Bluetooth, NFC) and both SIM card-based and remote server-based authentication. This multi-functionality enables the terminal to operate as different types of devices (mobile phone, data card, hotspot device) and access services from any service provider network through a single unified interface
3Adaptability or versatility
If a terminal establishes connections with service providers using physical SIM cards, then it can access voice and data services, but it is restricted to services provided by the current SIM card's service provider only
Solution Approach 1:
The terminal implements self-service capability by automatically managing authentication with service provider networks. When connected to a network, the terminal can autonomously establish communication with the remote server, retrieve authentication information, and access services without requiring manual configuration or physical SIM card changes, thereby simplifying the user experience despite the enhanced functionality

AI summary
Disclosed is a multi-channel communication terminal, the multi-channel communication terminal supporting at least two communication channels; wherein the first communication channel is established by a first service provider system, and configured to acquire subscriber identity information assigned by a remote server and providing service sharing; and the second communication channel is established by a second service provider system according to the subscriber identity information, and configured to acquire a service provided by the second service provider system. A subscriber acquires appropriate subscriber identity information according to actual requirements, and communicates with a corresponding service provider system according to the subscriber identity information to acquire a service provided by the service provider system, thereby acquiring an international, inter-service provider, any-technology and mode, or any-service network access service.
