BTS Correlation Engine for Wireless Backhaul Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless service providers face high expenses and limited network monitoring capabilities due to reliance on leased circuit-switched connections for backhaul in wireless telecommunications networks, which also complicate the management of separate radio access and backhaul networks.
Innovation Solution
A system that integrates radio access network (RAN) and backhaul elements with a correlation engine to generate unified status information, allowing for efficient monitoring and management of base transceiver stations (BTS) using wireless communication links and packet-switched networks, eliminating the need for leased circuit-switched connections and enabling flexible configuration of backhaul options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If leased circuit-switched connections are used for backhaul, then network connectivity is provided, but operational costs increase and network monitoring capabilities are limited
Solution Approach 1:
The patent replaces expensive leased circuit-switched connections with wireless backhaul links that use available radio resources. The wireless backhaul utilizes packet-switched networks and leverages existing wireless infrastructure, eliminating the need for costly dedicated physical connections while maintaining reliable network connectivity.
2Adaptability or versatility
If separate RAN and backhaul networks are operated, then wireless backhaul communication is enabled, but management complexity increases
Solution Approach 1:
The patent merges the management of RAN and backhaul networks by implementing a unified element management system that can manage both radio access network elements and backhaul network elements. This integration allows operators to monitor and control both networks through a single interface, reducing management complexity while maintaining the flexibility of separate wireless backhaul operations.
Solution Approach 2:
The element management system is designed with multi-functionality to handle both RAN and backhaul management tasks. It can perform configuration, monitoring, and control functions for diverse network elements including base stations, mobile switches, and backhaul network components, eliminating the need for separate management systems.
3Ease of operation
If two different element management systems are used, then RAN and backhaul elements can be managed, but overall network performance monitoring becomes difficult
Solution Approach 1:
The patent combines multiple element management systems into a unified system that provides comprehensive network performance monitoring. This unified system aggregates status information from both RAN and backhaul elements, enabling operators to view overall network performance in a single interface and making informed decisions based on complete network state information.

AI summary
A base transceiver station (BTS) includes a radio access network (RAN) interface for communicating with mobile stations and a backhaul interface for communicating with a backhaul network. A RAN element management system generates RAN status information based on event notifications from the RAN interface. A backhaul element management system generates backhaul status information based on event notifications from the backhaul interface. A correlation engine generates correlated status information for the BTS based on the RAN status information and the backhaul status information. The correlated status information indicates performance of the RAN interface in combination with the backhaul interface. The correlated status information is monitored at a network management system (NMS). The NMS may be used to take corrective actions to address problems identified in the correlated status information.
