Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current wireless communication systems lack an efficient method for users to transfer authorization capability among multiple devices under the same user service account, often relying on physical card transfer or simultaneous authentication, which is inefficient.

Innovation Solution

The system enables multi-device authorization by sharing and matching device IDs and event times between wireless communication devices and an authorization server, allowing seamless access to wireless communication services across multiple devices under a single user account.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If physical card transfer is used to transfer authorization capability between devices, then authorization transfer is achieved, but the process is inefficient and cumbersome

Engineering Contradiction:

Improveauthorization transfer processVSAvoidtime required for authorization transfer

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the mechanical physical card transfer system with an electronic authorization transfer system. Instead of physically moving a card between devices, the system uses electronic communication to transfer device identifiers and event times between devices and the authorization server, enabling seamless authorization transfer without physical intervention.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates an electronic copy of the authorization data (device identifier and event time) from one device to another. The second device receives and stores copies of these parameters, allowing it to present the same authorization credentials to the network without requiring the original physical card or device.

Inventive Principle:

Principle #26Copying

2Adaptability or versatility

If multiple devices control authentication simultaneously, then authorization capability can be transferred, but the system complexity increases

Engineering Contradiction:

Improvemulti-device authorization capabilityVSAvoidauthentication system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent performs preliminary actions by having the first device obtain and store the device identifier and event time parameters before the actual authorization transfer occurs. The authorization server also pre-records these parameters in its database, so when the second device needs authorization, the matching process can proceed efficiently without complex real-time coordination between multiple devices.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The authorization server acts as an intermediary that manages the authorization data between multiple devices. Instead of having devices directly communicate and coordinate complex authentication protocols, the server receives parameters from devices, performs the matching operation, and grants authorization, thereby simplifying the overall system architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If device ID and event time are shared between devices, then seamless authorization transfer is achieved, but security requirements increase

Engineering Contradiction:

Improveauthorization transfer efficiencyVSAvoidauthorization security

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent segments the authorization verification process into distinct components: the first device generates device identifier and event time parameters, the authorization server stores and manages these parameters separately in its database, and the second device presents these parameters for verification. This segmentation allows for efficient automated processing while maintaining security through distributed validation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The authorization server provides feedback by comparing the device identifier and event time parameters received from the second device against the stored parameters from the first device. This feedback mechanism ensures security by verifying that the transferring device possesses the correct authorization credentials before granting access, while enabling efficient automated authorization transfer.

Inventive Principle:

Principle #23Feedback

AI summary

In a wireless communication system, a first wireless device transfers an authorization request to an authorization server, and the authorization server authorizes the first wireless device to access a wireless communication network under a user service account. The first wireless device and the server store data indicating the first device identifier and an event time for a communication event that occurs for the first wireless device. The wireless device transfers data indicating a first device identifier and the event time to a second wireless device. The second wireless device transfers an authorization request to the authorization server that indicates a second device identifier, the first device identifier, and the event time. The authorization server determines that the event times match, and in response, authorizes the second wireless device to access the wireless communication network under the user service account.
