Predictive Dedicated Bearer Establishment in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, there is a delay in establishing bearers, particularly dedicated bearers, which can lead to non-guaranteed quality of service (QoS) until they are established, and are susceptible to congestion, impacting performance, especially for time-sensitive applications.
Innovation Solution
A method and apparatus that collect data from communication sessions to predict when a dedicated bearer will be needed, initiating its establishment at a predicted time if the likelihood exceeds a threshold, and deactivating it if not used within a specified period, thereby reducing delays and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If dedicated bearers are established on demand, then resource usage is optimized, but delay in establishing bearers increases and QoS cannot be guaranteed
Solution Approach 1:
The system performs preliminary actions by collecting data from communication sessions and calculating likelihood of dedicated bearer establishment in advance. The network node predicts future bearer establishment events and initiates bearer setup proactively before the actual need arises, thereby eliminating delays while maintaining resource efficiency through conditional establishment based on predicted likelihood thresholds.
2Reliability
If dedicated bearers are established proactively, then QoS is improved, but network congestion increases
Solution Approach 1:
The system implements feedback mechanisms by continuously collecting data from communication sessions and using this information to calculate the likelihood of dedicated bearer establishment. The network node adjusts its proactive bearer establishment decisions based on this feedback, initiating bearers only when the calculated likelihood exceeds a predetermined threshold, thereby improving QoS while avoiding unnecessary bearers that would contribute to congestion.
3Loss of time
If data collection and prediction mechanisms are implemented, then bearer establishment timing is optimized, but device complexity increases
Solution Approach 1:
The network node performs self-service by autonomously collecting data from communication sessions, calculating likelihood of dedicated bearer establishment, and making decisions about when to establish bearers without requiring complex external control systems. The prediction mechanism is integrated into the existing network infrastructure, allowing the system to optimize bearer establishment timing while minimizing additional complexity through self-contained predictive capabilities.

AI summary
A method of establishing bearers for a device in a wireless communication network, including collecting for the device data over a period of time from communication sessions the device participates in, at least some of the communication sessions being supported by a default bearer and a dedicated bearer; calculating from the collected data a likelihood a dedicated bearer will be established for the device at one or more different times values, and predicting the dedicated bearer will be established for the device at a time value if the likelihood of establishment at that time value exceeds a specified threshold; and initiating establishment of the dedicated bearer to establish the dedicated bearer for the predicted time value.
