Mobile Device PDP Context Provisioning via Intermediary Data Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communications devices struggle with provisioning over the air, particularly due to limitations in web browsers' capability to retrieve and use PIN and device identifier information, and the inability to support simultaneous activation of multiple PDP contexts.
Innovation Solution
Establishing a method and apparatus for a mobile communications device to create sequential PDP contexts, where a non-web based data context is used to request and receive parameters from a registration server, which are then used to establish a web-based data context with a provisioning system for seamless over-the-air provisioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile communications device uses a web browser to retrieve PIN and device identifier information, then the device can access provisioning systems, but the web browser cannot properly retrieve and use the required parameters for provisioning
Solution Approach 1:
The patent introduces a non-web based data context as an intermediary mechanism between the mobile device and the provisioning system. This intermediary allows reliable parameter retrieval without relying on the web browser's limited capabilities, resolving the contradiction between ease of operation and reliability.
2Adaptability or versatility
If the mobile communications device supports simultaneous activation of multiple PDP contexts, then the device can establish both web-based and non-web based data contexts, but the device cannot support multiple active PDP contexts
Solution Approach 1:
The patent segments the provisioning process into two distinct phases using sequential PDP contexts: a non-web based data context for parameter retrieval and a web-based data context for actual provisioning. This segmentation allows the device to manage limited PDP context support while achieving the functionality of multiple contexts through time-separated execution.
Solution Approach 2:
The patent performs preliminary parameter retrieval and storage in a non-web based data context before establishing the web-based data context for provisioning. This preliminary action allows the device to prepare necessary parameters in advance, enabling the subsequent web-based provisioning to proceed successfully without requiring simultaneous multiple PDP contexts.
3Reliability
If the device uses sequential PDP contexts for provisioning, then the device can overcome single PDP context limitations, but the provisioning process becomes more complex with multiple context establishment steps
Solution Approach 1:
The non-web based data context serves as an intermediary that simplifies the overall provisioning process by handling parameter retrieval separately from the web-based provisioning. This intermediary approach, while adding a step, actually reduces complexity by isolating the parameter retrieval function from the provisioning function.
Data Source
AI summary
A mobile communications device and registration server and methods of use thereof. The mobile communications device comprises means for establishing a first data context and means for establishing a second data context. The first data context is established to transmit a request for parameters from the mobile communications device to a first network node and to receive at the mobile communications device a response from the first network node including the parameters. The second data context is established by transmitting the parameters from the mobile communications device to the second network node.
