Dynamic Hold-Timer Setting for Wireless Network Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for setting hold-timer durations in wireless communication networks, such as LTE and CDMA, use static values, leading to inefficiencies like resource wastage and delayed reconnection, as they do not account for varying network loads, data-service types, and estimated call durations, which can result in suboptimal resource allocation and user experience.
Innovation Solution
A method and system that dynamically set hold-timer durations based on network load, data-service type, and estimated call duration to optimize resource allocation, allowing for timely release and reclamation of resources, thereby improving network efficiency and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static hold-timer durations are used, then resource allocation is simplified, but resource utilization efficiency deteriorates due to wastage and delayed reconnection
Solution Approach 1:
The patent applies dynamics by transitioning from static hold-timer values to dynamic hold-timer values that are adjusted based on network conditions. The network node dynamically determines hold-timer durations considering factors like network load, service type, and UE behavior patterns, allowing the system to adapt resource allocation to changing conditions and improve resource utilization efficiency.
Solution Approach 2:
The patent implements parameter changes by modifying the hold-timer duration parameter based on multiple variables including network load conditions, data service types, estimated call durations, and UE-specific behaviors. This allows the system to optimize resource allocation by changing the temporal parameter (hold-timer duration) according to actual network state and service requirements.
2Reliability
If longer hold-timer durations are used, then resource availability for returning UEs is improved, but resource wastage increases when UEs do not return
Solution Approach 1:
The patent uses parameter changes to adjust hold-timer durations based on service type, network load, and estimated call duration. For example, shorter hold-timers are applied for services with low return probability or during high network load conditions, while longer hold-timers are used for services with high return probability or during low network load, thereby optimizing the balance between resource availability and wastage prevention.
Solution Approach 2:
The patent applies local quality by differentiating hold-timer durations for different UEs, services, and network conditions rather than using a uniform timer. The network node selectively applies different timer values based on specific UE behaviors, service types (e.g., voice vs. data), and local network load conditions, allowing optimized resource management for each scenario.
3Productivity
If network load conditions are considered for hold-timer setting, then resource allocation efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the network node continuously monitors network load conditions, service types, and UE behavior patterns, then uses this feedback information to dynamically adjust hold-timer durations. The system collects data on UE reconnection patterns and service outcomes, refining its hold-timer decisions based on this feedback to improve resource allocation efficiency while managing system complexity through learned patterns.
Data Source
AI summary
A method and system for setting a hold-timer duration is disclosed. The method involves a first network initially serving a UE by providing the UE with data service, wherein serving the UE includes allocating at least one resource to the UE and using the at least one resource to serve the UE. The method further involves, setting a hold-timer duration for a hold-timer for release of the at least one resource that the first network allocated to the UE, wherein setting the hold-timer duration comprises (i) making at least one determination selected from the group consisting of (a) a determination of a network load of the first network, (b) a determination of a data-service type of the data service, and (c) a determination of an estimated call duration for the UE and (ii) using the at least one determination as a basis to set the hold-timer duration.
