Base Station Resource Allocation for LTE-WLAN Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems using LTE-WLAN Aggregation technology, multiple user equipment devices competing for the same wireless network resources lead to inefficient resource allocation, preventing effective bandwidth sharing among devices.
Innovation Solution
A base station device determines the order of wireless network access points for user mobile devices to register based on signal intensity and user device counts, using two tables to prioritize access points with higher signal strength and fewer registered users, ensuring optimal resource allocation and minimizing interference.

Engineering Contradiction Analysis
1Productivity
If multiple user equipment devices simultaneously use LWA technology in the same wireless network environment, then bandwidth enhancement is achieved for each device, but resource allocation efficiency deteriorates due to rushed access to the same network
Solution Approach 1:
The base station performs preliminary actions by determining the registration order of access points for each user equipment before actual registration occurs. This is achieved by obtaining signal intensity measurements and counts of registered devices, then calculating and storing the optimal registration sequence in advance, preventing resource allocation conflicts before they arise
Solution Approach 2:
The system dynamically adjusts resource allocation based on real-time conditions. The registration order is not fixed but is continuously updated based on changing signal intensities and device counts. The base station re-evaluates and re-determines registration sequences as network conditions change, making the resource allocation adaptive and flexible
2Productivity
If no resource allocation method is implemented, then device operation is simple, but data transmission performance deteriorates as no user equipment can share benefits of resource aggregation
Solution Approach 1:
The base station acts as an intermediary that mediates between user equipment devices and access points. It receives signal intensity measurements from devices, obtains counts of registered devices from access points, determines optimal registration orders, and provides this allocation information back to devices. This intermediary function enables efficient resource sharing without requiring complex direct negotiations between devices and access points
Solution Approach 2:
The system implements feedback mechanisms where the base station continuously monitors signal intensities measured by user equipment and counts of registered devices at access points. Based on this feedback information, the base station dynamically adjusts and re-determines registration orders to optimize data transmission performance while managing resource allocation complexity
3Speed
If user equipment devices rush to register at the same access point, then registration speed is fast, but resource sharing efficiency deteriorates
Solution Approach 1:
The base station determines the registration order in advance before devices actually attempt to register. By calculating the optimal sequence based on signal intensity and current device counts, the system prevents registration conflicts and ensures efficient resource sharing from the outset, maintaining both speed and efficiency

AI summary
An allocation method of communication resources is use with at least a user mobile device, at least first and second wireless network access point devices, and a base station device for mobile communication. In the allocation method, the base station device receives a registration request from the user mobile device; and the base station device determines an order of the first and second wireless network access point devices for the user mobile device to register in according to intensities of signals of the first and second wireless network access point devices, which are measured by the user mobile device, and counts of user mobile devices having registered in the first and second wireless network access point devices, respectively.
