Online Charging System Pre-allocating Resources for Large File Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current online charging systems in wireless networks require multiple messages for authorization renewal during sessions with large files or long durations, leading to inefficient resource allocation and increased signaling burden.
Innovation Solution
An electronic device in the online charging system receives a request message indicating a session with a large file or long duration, determines the terminal device's credit availability, and grants resources accordingly, reducing the need for multiple authorization renewal messages by pre-allocating necessary credits based on the session information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple authorization renewal messages are used for sessions with large files or long durations, then the terminal device can maintain continuous resource usage, but the signaling burden and system complexity increase
Solution Approach 1:
The online charging system performs preliminary evaluation of the terminal device's credit balance and pre-allocates sufficient resources for the entire session duration before the session actually begins. By assessing the large file indication or long duration parameter in advance and determining adequate credit allocation upfront, the system eliminates the need for multiple subsequent authorization renewal messages, thereby reducing signaling burden while ensuring continuous resource availability.
2Ease of manufacture
If pre-defined logic is used to determine resource amounts, then the charging system operation is simplified, but the resource allocation efficiency for large files or long sessions deteriorates
Solution Approach 1:
The system dynamically adjusts the resource allocation strategy based on the specific characteristics of each session. When a large file indication or long duration parameter is detected, the system activates a specialized pre-allocation mechanism that evaluates the terminal device's credit balance and determines appropriate resource amounts tailored to the session requirements. This dynamic approach maintains operational simplicity through automated credit assessment while significantly improving resource allocation efficiency for demanding sessions.

AI summary
Methods and systems for an online charging system to grant resources to a session with a terminal device when the session includes a large file or the session has a long duration. Embodiments the invention include methods performed by an electronic device for online charging in a wireless network. In one embodiment, the electronic device receives a request message for resources to set up a session with a terminal device, where the request message is sent from a core network interface to an online charging function (OCF), and where the request message indicates that the session includes a large file or that the session has a long duration. The electronic device determines that the terminal device has enough credit for the session based on the request message and grants the resources for the session with the terminal device based on the determination.
