Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of devices accessing the mobile communication system poses a challenge in managing resources effectively, leading to congestion and the need for improved time-controlled access management to ensure high-speed data services.
Innovation Solution
A method where a mobility management entity (MME) and a home subscriber server (HSS) collaborate to provide time control information, including forbidden and granted time intervals, to user equipment (UE), allowing network access only during designated granted times and blocking access during forbidden times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If time-controlled access management is implemented to manage numerous terminals, then network congestion is reduced and service quality is maintained, but network access flexibility and user convenience deteriorate
Solution Approach 1:
The patent implements dynamic access control by allowing the MME to adjust time control information based on network conditions and subscriber profiles. The system dynamically grants or forbids access during specific time intervals, enabling flexible resource allocation that adapts to varying network loads while maintaining service quality for authorized users.
Solution Approach 2:
The patent changes the time parameter of network access by introducing forbidden time intervals (FTI) and granted time intervals (GTI). The MME modifies access parameters based on network congestion levels, subscriber type, and service priority, allowing the system to control access timing without permanently restricting user capabilities.
2Ease of operation
If all terminals are allowed to access the network simultaneously, then network access convenience is improved, but network congestion increases and resource insufficiency worsens
Solution Approach 1:
The patent implements periodic access control where terminals are granted network access during specific time intervals (GTI) and restricted during others (FTI). This periodic gating mechanism distributes network load across different time periods, preventing simultaneous access by all terminals while maintaining convenient access for authorized users during their granted intervals.
Solution Approach 2:
The patent performs preliminary authorization by the HSS before network access is granted. The home subscriber server pre-determines which terminals are authorized to access the network during specific time intervals, allowing the MME to enforce access control decisions without real-time negotiation, thus maintaining access convenience for authorized users while preventing resource overload.
3Productivity
If time control information is stored and managed in the MME, then access control efficiency is improved, but the complexity of the MME increases
Solution Approach 1:
The patent extracts the complex task of time control information management from the MME and relocates it to the HSS. The HSS stores and manages the detailed time control information (forbidden time intervals and granted time intervals) for each subscriber, while the MME only needs to retrieve and enforce these pre-determined time windows, significantly reducing MME complexity while maintaining access control efficiency.
Solution Approach 2:
The patent introduces the HSS as an intermediary between the subscriber and the MME for time control management. The HSS acts as a mediator that handles the complex tasks of storing, updating, and managing time control information, while the MME serves as an enforcer that simply applies the time control decisions provided by the HSS, dividing the system's functional complexity across appropriate components.
