Remote Buffer Status Maintenance via Third-Party Model Copying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication network technologies face challenges in efficiently sharing communication resources among devices due to the difficulty in determining when each device has data to transmit, leading to increased network overhead in communicating Buffer Status Reports (BSRs).
Innovation Solution
A method and apparatus for maintaining a device's buffer status indication remotely, using a third-party device to generate and transmit buffer status information to a communication network scheduler, allowing the scheduler to schedule communications based on this information, with a local and remote model of the buffer status being maintained and updated to mitigate any discrepancies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If Buffer Status Reports (BSRs) are communicated to provide accurate buffer status information, then scheduling accuracy is improved, but network overhead increases
Solution Approach 1:
The patent creates a copy of the buffer status model at a remote device (third-party device) that is separate from the actual communication device. This remote model continuously tracks buffer status without requiring direct communication with the communication device, thereby providing accurate buffer status information to the scheduler while eliminating the need for frequent BSR transmissions that would increase network overhead.
Solution Approach 2:
The patent introduces a third-party device as an intermediary between the communication device and the scheduler. This intermediary maintains a model of the buffer status and provides this information to the scheduler, acting as a mediator that eliminates the need for direct BSR communications from the communication device to the scheduler, thus reducing network overhead while maintaining information accuracy.
2Speed
If frequent Buffer Status Reports are transmitted to keep scheduler updated, then scheduling timeliness is improved, but communication resources are consumed
Solution Approach 1:
The patent performs preliminary action by maintaining a continuous model of buffer status at the remote third-party device before the scheduler needs this information for scheduling decisions. The model is updated in advance based on communication device behavior patterns, so when scheduling is needed, the information is already ready, improving scheduling timeliness without requiring frequent real-time communications.
Solution Approach 2:
By creating a copy of the buffer status model at a remote location, the system can provide timely scheduling information without requiring frequent direct communications with the communication device. The remote model continuously tracks buffer status and can immediately provide updated information to the scheduler when needed, improving response time while consuming fewer communication resources.
3Measurement precision
If direct buffer status monitoring is implemented at the scheduler, then scheduling accuracy is improved, but device complexity increases
Solution Approach 1:
The patent introduces a third-party device as an intermediary that maintains the buffer status model. This intermediary absorbs the complexity of monitoring and modeling buffer status, keeping the scheduler simpler while still providing accurate buffer status information. The third-party device handles the complex tasks of tracking buffer status changes and predicting future states, thereby reducing scheduler complexity while maintaining high measurement precision.
Solution Approach 2:
Instead of implementing direct buffer status monitoring at the scheduler itself, the patent creates a copy of this functionality at a separate third-party device. This copying approach allows the scheduler to remain simpler while still accessing accurate buffer status information through the remote model maintained by the third-party device.
Data Source
AI summary
A method and system for supporting operation of a scheduler by providing indications of communication device transmit buffer status is provided. The indication of buffer status can be generated by a third-party device which is external to both the communication device and the scheduler. In some embodiments matched local and remote models of the buffer are maintained at the communication device and third-party device (or scheduler), respectively. The communication device monitors locally for drift of the model from the actual buffer status. When a level of mismatch in the model is detected, both the local and remote models are updated to mitigate the mismatch.
