Wireless Network Resource Reset via Segmented Message Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current procedures for resetting network resources in wireless networks, such as those in the UTRAN system, face challenges with message congestion and latency as the number of users increases, particularly in 3G and GSM networks, necessitating a more efficient method to manage resource resets.
Innovation Solution
The proposed solution involves providing pairs of information elements that define ranges of identifiers associated with network resources to be reset, allowing for a more efficient reset procedure by reducing the size of reset messages and improving RANAP efficiency, enabling partial network resets without delay or interface congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional reset procedures are used to reset network resources in UTRAN, then all affected references are cleared and resources are released, but message congestion and latency occur as the number of users increases
Solution Approach 1:
The invention segments the reset procedure by introducing a two-stage process: first sending a RESET message to initiate resource release, then separately sending a RESET ACKNOWLEDGE message to clear references. This segmentation allows the reset operation to proceed without blocking the interface with large acknowledgment messages, thereby reducing message congestion and latency while maintaining complete resource reset reliability.
2Reliability
If a RANAP RESET message is sent to clear all references and release resources, then network resource reset is achieved, but the message size and interface congestion increase
Solution Approach 1:
The invention extracts the acknowledgment function from the original large RESET message by creating a separate, minimal RESET ACKNOWLEDGE message. This extracted acknowledgment message contains only essential confirmation information, significantly reducing the message size transmitted over the interface while ensuring complete reference clearing through the separated acknowledgment stage.
3Reliability
If guard period is introduced between RESET and RESET ACKNOWLEDGE messages, then reference clearing is ensured, but reset procedure latency increases
Solution Approach 1:
The invention implements periodic action by introducing a guard period between the RESET and RESET ACKNOWLEDGE messages. This guard period is a predetermined time interval that ensures proper sequence processing and reference clearing. By making the timing periodic and predictable, the system ensures reliable reference clearing while allowing for optimized time management in the reset procedure.

AI summary
The proposed technology relates to methods and network nodes for enabling resetting of network resources in a wireless network. For example, a method performed by a first network node (10) comprises the step (S10) of providing at least one pair of information elements, each pair defining a respective range of identifiers within a list of identifiers, wherein each identifier within each range of identifiers is associated with a respective network resource to be reset.
