FAP Service Redirection via Capability Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In WiMAX technology, terminals are unable to determine whether a femto access point (FAP) supports the required service, leading to inefficiencies in service implementation due to potential misselection of base stations.
Innovation Solution
A method where the FAP acquires and sends information about base stations supporting the required service to the terminal, allowing the terminal to select a target base station effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal randomly selects a FAP without capability information, then the FAP deployment is simple, but the service implementation efficiency is low due to terminal incapable of learning whether the FAP can provide the support capability
Solution Approach 1:
The FAP management entity performs preliminary actions by pre-configuring and maintaining capability information of FAPs in a database before service requests are made. When a terminal sends a service request, the FAP management entity has already prepared the capability information, allowing the terminal to directly query and select appropriate FAPs without real-time complex evaluations.
Solution Approach 2:
The system establishes a feedback mechanism where the FAP management entity provides capability information about FAPs to terminals through the network. This feedback loop allows terminals to learn whether FAPs can provide specific services based on previously stored capability data, enabling informed selection without requiring complex real-time verification.
2Reliability
If the terminal performs blind reslection when FAP cannot provide service, then the terminal can try alternative FAPs, but the efficiency is lowered because whether the reselected FAP can provide the support capability is still uncertain
Solution Approach 1:
The FAP management entity performs preliminary action by pre-storing capability information of multiple FAPs in advance. When a terminal needs service, this pre-prepared information is immediately available for query, eliminating the need for time-consuming capability verification during the service selection process.
Solution Approach 2:
The FAP management entity acts as an intermediary between terminals and FAPs, maintaining and providing capability information. This intermediary role allows terminals to access reliable capability data without directly querying each FAP, reducing selection time while ensuring reliability.
3Ease of operation
If the FAP provides detailed capability information to terminals, then the terminal can make informed base station selection, but the FAP management system becomes more complex
Solution Approach 1:
The FAP management entity serves as an intermediary that handles the complexity of capability information management. It collects, stores, and provides this information to terminals through standardized interfaces, simplifying the terminal's task while centralizing the management complexity in a dedicated entity.
Solution Approach 2:
The FAP management entity performs multiple functions: maintaining capability databases, processing service requests, providing capability information to terminals, and coordinating FAP selections. This multi-functionality consolidates what would otherwise be distributed complexity into a single manageable system component.

AI summary
A redirection method, a redirection device, and a communication system in the field of communication technology are provided. The redirection method includes the following steps: A femto access point (FAP) receives a message, in which the message contains information of a service required by a terminal. After the FAP determines that it does not support the service, the FAP acquires information of base stations supporting the service. The FAP sends the information of the base stations supporting the service to the terminal, so as to enable the terminal to determine a target base station according to the information of the base stations supporting the service. Therefore, the terminal is redirected to the target base station supporting the service required by the terminal, and efficiency of implementing the required service by the terminal is increased.
