LTE Resource Status Measurement Modification Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE systems lack a mechanism to easily modify or end resource status measurements during network operation after initiating multiple resource status measurements among base stations.
Innovation Solution
A method for measuring and reporting resources in LTE systems, where a source base station can encapsulate a resource status request message with a 'modify' option in the measurement request type, allowing for adjustments to measurement configuration, and includes features like measurement IDs, reporting periods, and directions for hardware load, transmission bandwidth, and PRB usage, enabling flexible modification and termination of measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple resource status measurements are initiated among base stations, then comprehensive resource monitoring is achieved, but the system lacks flexibility to modify or terminate measurements during operation
Solution Approach 1:
The measurement request type is made dynamic by introducing multiple enumeration values (start, end, modify) that allow the measurement configuration to be changed during operation. The source eNB can send new measurement requests with updated parameters or terminate existing measurements, transforming a static measurement system into a dynamic one that adapts to changing network conditions.
Solution Approach 2:
The invention enables parameter changes by allowing the source eNB to modify measurement configuration parameters (such as measurement parameters, reporting period, or cell list) by sending a new measurement request with the updated configuration. This changes the measurement parameters from fixed to modifiable, enabling flexible adaptation without system redesign.
2Adaptability or versatility
If measurement configuration is modified during operation, then adaptability improves, but information exchange overhead increases
Solution Approach 1:
The invention extracts only the essential modification information from the complete measurement configuration. When modifying measurements, the system sends only the changed parameters (measurement request type set to 'modify' along with updated configuration) rather than transmitting entire configuration sets, thereby reducing information overhead while maintaining adaptability.
Solution Approach 2:
The measurement management is segmented into distinct operations (start, modify, end) represented by enumeration values. This segmentation allows the system to handle measurement modifications as discrete, targeted actions rather than comprehensive reconfigurations, reducing the amount of information that needs to be exchanged for each operation.
3Measurement precision
If comprehensive resource status information is reported, then measurement precision improves, but network load increases
Solution Approach 1:
The invention applies partial action by allowing the source eNB to selectively measure and report only specific resource status parameters based on current network needs. The measurement configuration can be tailored to include only the necessary parameters (hardware load, S1 interface load, PRB usage, etc.) rather than reporting all possible metrics, achieving sufficient precision with reduced network load.
Solution Approach 2:
The measurement reporting is structured as periodic action with configurable reporting periods. The target eNB reports resource status information at defined intervals rather than continuously, and the source eNB can adjust the reporting period in modification requests. This periodic approach maintains measurement precision while significantly reducing network load compared to continuous reporting.

AI summary
A method for measuring and reporting resource in a long term evolution system comprises: a source base station encapsulating a resource status request message and sending the message to a target base station; after receiving the resource status request message, the target base station processing the message, and sending a resource status success response to the source base station if the processing is successful, or else sending a resource status failure response if the processing is failed; the source base station encapsulating at least a message type (2), a measurement request type (3), a source base station global identifier (4) and measurement configuration information (5) in the resource status request message, wherein, the measurement request type (3) is one or more of start, modify and end (7); the measurement configuration information (5) is measurement configuration information (5)in current measurement request type (3). The method makes it convenient to start, modify or end the current measurement by the target base station during network operation after a plurality of resource status measuring and reporting are launched between base stations, and thus reducing the number of information exchange between base stations.
