Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies lack a solution for implementing signaling interaction between wireless controllers and RAT control modules, hindering the control of various radio access technologies (RATs) in a unified manner.
Innovation Solution
A communication method where a wireless controller receives an identifier and address information from a network management device, registers attribute information of a slave control device, establishes a mapping relationship, and uses this information to communicate with slave control devices or RAT control modules, enabling interaction between wireless controllers and RAT control modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless controller uses independent IP addresses or URLs for different RAT control modules, then communication between different RATs can be established, but device complexity and difficulty of management increase
Solution Approach 1:
The patent merges multiple RAT control modules (LTE, UMTS, WiFi) into a single wireless controller entity, allowing them to share common resources including IP address, URL, and management functions. This consolidation enables communication between different RATs while reducing the complexity of managing separate controllers for each RAT type.
Solution Approach 2:
The wireless controller is designed as a universal platform that can simultaneously control multiple types of radio access technologies. By implementing a multi-functional architecture where a single controller handles LTE, UMTS, and WiFi operations, the system achieves adaptability across different RATs without requiring separate specialized controllers for each technology.
2Adaptability or versatility
If wireless controller manages multiple RAT control modules with separate management functions, then each RAT can be controlled independently, but signaling interaction and coordination between controllers become difficult
Solution Approach 1:
The patent combines multiple RAT control modules under a single wireless controller management entity, eliminating the need for complex inter-controller signaling. The unified controller can directly coordinate between LTE, UMTS, and WiFi modules internally, simplifying the signaling interaction that would otherwise require separate management protocols between multiple independent controllers.
Solution Approach 2:
The unified wireless controller acts as an intermediary that manages all RAT control modules through a common interface and resource pool. This mediator approach allows independent control of each RAT while providing centralized coordination, avoiding the complexity of direct peer-to-peer signaling between multiple specialized controllers.
3Device complexity
If wireless controller shares common resources among multiple RAT control modules, then device complexity is reduced, but resource allocation and conflict management become challenging
Solution Approach 1:
The patent implements dynamic resource allocation mechanisms within the wireless controller, allowing the system to adaptively assign and reassign common resources (IP addresses, URLs, processing power) to different RAT control modules based on real-time requirements. This dynamic approach enables the simplified architecture to effectively handle diverse resource allocation demands across LTE, UMTS, and WiFi operations.

AI summary
A wireless controller communication method and a wireless controller are provided. The method comprises: receiving, by the wireless controller, an identifier and address information allocated to the wireless controller by a network management device; registering, by the wireless controller, attribute information of a slave control device belonging to the wireless controller with the network management device, wherein the network management device establishes a mapping relationship between the wireless controller and the slave control device; searching for address information of the slave control device based on the mapping relationship when the wireless controller needs to communicate with the slave control device; and establishing, by the wireless controller, communication with the slave control device based on the address information of the slave control device.
