Remote Mobile Device Control via PDSN IP Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile device users face inconvenience due to the potential misuse of their lost devices, as others can access personal information and use services, and there is a need for remote control capabilities without additional server installations.
Innovation Solution
A method and system for remotely controlling a mobile device using a host terminal connected to a Packet Data Serving Node (PDSN), which allocates IP addresses and establishes a data communication channel with a client terminal, allowing the host terminal to control the client terminal via text messages and user interface screen manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control functionality is added to mobile devices, then user convenience and security are improved, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality by enabling the mobile device to serve both as a standalone device and as a remotely controlled device. The same device can be accessed and controlled from different locations without requiring separate hardware systems, thus improving ease of operation while managing complexity through existing device capabilities.
Solution Approach 2:
The patent introduces a server as an intermediary component that facilitates remote control operations. This server acts as a mediator between the mobile device and the user's remote location, handling communication protocols, authentication, and control signal transmission. By centralizing these complex functions in a dedicated server, the mobile device itself doesn't need to incorporate all control logic, thus managing overall system complexity.
2Adaptability or versatility
If additional servers are installed for remote control, then remote control functionality is achieved, but system complexity and cost increase
Solution Approach 1:
The patent implements self-service by enabling the mobile device to initiate and manage its own remote control setup. The device automatically obtains IP addresses, establishes communication channels, and configures itself for remote access without requiring manual server configuration or complex setup procedures. This reduces the operational complexity of deploying and maintaining remote control functionality.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the mobile device with remote control capabilities and authentication mechanisms before actual use. The device is prepared in advance with the necessary software components and communication protocols, so when remote control is needed, the setup process is streamlined and doesn't require complex real-time configuration, thus reducing overall system complexity.
Data Source
AI summary
A remote control method and system of a mobile device are provided. The method includes connecting a host terminal to a Packet Data Serving Node (PDSN) and allocating a first Internet Protocol (IP) address to the host terminal when a remote control mode is executed, creating, by the host terminal, a text message containing the first IP address and transmitting the text message to a client terminal, connecting the client terminal to the PDSN and allocating a second IP address to the client terminal, establishing a data communication channel between the host terminal and the client terminal using the first IP address and the second IP address, and remotely controlling, by the host terminal, the client terminal via the data communication channel.
