UICC PDP Context Parameter Management via ME Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current TCP/IP internet connectivity specifications in wireless telecommunication networks lack a mechanism for the UICC to provide PDP context parameters to the Mobile Equipment (ME) for data connections, leading to redundant operations and limited flexibility, especially as data connections over TCP/IP should replace SIP from rel-7 applications onwards.
Innovation Solution
A method where the UICC sends PDP context parameters to the ME using specific commands for activating or deactivating PDP contexts, with the ME notifying the UICC of status changes and using an 'always on' APN to minimize redundant operations, and allowing dynamic updates via Over The Air mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the UICC uses default parameters to establish data connections, then the Mobile Equipment can simplify the connection setup, but the UICC loses flexibility and control over connection parameters
Solution Approach 1:
The patent implements a feedback mechanism where the ME notifies the UICC about PDP context status changes (activation/deactivation). This allows the UICC to receive information about the current state of data connections and adjust its behavior accordingly, resolving the contradiction by enabling both simplified operation and flexible control through informed decision-making.
Solution Approach 2:
The patent introduces a specific command as an intermediary mechanism between the UICC and ME for transferring PDP context parameters. This intermediary structure enables the UICC to provide detailed connection parameters to the ME while maintaining system simplicity, thus resolving the contradiction between operational simplicity and parameter flexibility.
2Adaptability or versatility
If the UICC frequently activates/deactivates PDP contexts for multiple applications, then the UICC can accommodate growing number of applications, but redundant operations increase
Solution Approach 1:
The patent implements preliminary action by having the ME notify the UICC about PDP context status changes before the UICC needs to react. This advance information allows the UICC to prepare appropriate responses and avoid redundant activation/deactivation operations, thus maintaining high adaptability while improving operational efficiency.
Solution Approach 2:
The notification mechanism from ME to UICC about PDP context status serves as feedback that prevents redundant operations. The UICC receives real-time information about connection states and can make informed decisions about whether to activate new contexts or reuse existing ones, thereby accommodating multiple applications without unnecessary operational redundancy.
3Reliability
If the UICC requests PDP context activation for each application, then the UICC can ensure proper connection setup, but redundant activation requests increase
Solution Approach 1:
The feedback mechanism where the ME notifies the UICC about PDP context status changes enables the UICC to avoid redundant activation requests. By knowing the current state of connections through notifications, the UICC can confirm existing connections are suitable or only activate new ones when necessary, thus maintaining connection reliability while reducing time spent on redundant operations.
