WLAN Controller Cellular Coverage Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing enterprise seamless mobility solutions are hindered when a large block of WLAN access points fail, forcing mobile devices to connect to cellular networks with potentially poor signal quality, requiring manual adjustments by carriers to improve coverage.
Innovation Solution
An automated system that couples a WLAN access point controller with a cellular base receiver, allowing for automatic compensation by adjusting cellular network coverage and power levels using management protocols like 3GPP or SNMP, enabling seamless transition and restoration of service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adjustment by cellular carrier is used to improve coverage, then coverage and performance are improved, but complexity and time consumption increase
Solution Approach 1:
The system enables self-service automation where the access point controller automatically detects WLAN failures and triggers compensatory actions by instructing the base receiver to adjust cellular coverage parameters, eliminating the need for manual carrier intervention
Solution Approach 2:
The access point controller continuously monitors WLAN access point status and provides feedback to the base receiver, enabling dynamic adjustment of cellular coverage parameters in response to detected failures
2Loss of time
If automated configuration of mini cell site is implemented, then response time and coverage adjustment speed are improved, but system complexity increases
Solution Approach 1:
The system merges the access point controller and base receiver into a coordinated automated system where the access point controller monitors WLAN status and automatically instructs the base receiver to adjust cellular coverage, combining monitoring and control functions
Solution Approach 2:
The base receiver is pre-configured with the ability to receive automated instructions from the access point controller and execute coverage adjustments, so that when WLAN failures are detected, the system can immediately respond without delay

AI summary
A wireless communication system (100) or method (300) to compensate for failed network access using disparate access technologies can include an access point controller (109) for a first wireless access technology (such as wireless local area network) coupled to a wide area base receiver (106) for a second wireless access technology (such as a wireless cellular network) and a processor (150) forming a portion of the access point controller. The processor can be programmed to monitor the first wireless access technology for wireless access failures and automatically instruct the second wireless access technology to compensate for the wireless access failures of the first wireless access technology. The processor can automatically instruct by instructing the wide area base receiver to compensate for a failure of first wireless access technology or by instructing the wide area base receiver to increase cellular coverage in areas specified by the access point controller.
