Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently identifying and selecting the most suitable access points for seamless communication, particularly in environments with restricted association, where mobile devices struggle to differentiate between macrocells and femtocells and manage restricted access points.
Innovation Solution
The use of pilot identifiers transmitted by access points to classify and identify their types, allowing mobile devices to determine the type of access point based on the pilot identifier range, facilitating efficient cell reselection and connection management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile devices measure and rank multiple access points for cell reselection, then communication reliability is improved, but device complexity and processing time increase
Solution Approach 1:
The patent segments access points into different types (macrocells and femtocells) based on pilot identifier ranges. This classification allows mobile devices to process cell reselection information more efficiently by handling different access point types through distinct procedures, thereby improving reliability without proportionally increasing device complexity.
Solution Approach 2:
The patent implements preliminary identification of access point types through pilot signal detection before full connection establishment. By determining access point type in advance using pilot identifier ranges, the system prepares necessary connection parameters beforehand, reducing real-time processing complexity while maintaining reliable communication selection.
2Measurement precision
If mobile devices differentiate between macrocells and femtocells using pilot identifiers, then connection accuracy is improved, but signal processing requirements increase
Solution Approach 1:
The patent utilizes pilot identifier ranges as a distinguishing parameter to differentiate between macrocells and femtocells. By assigning specific identifier ranges to different access point types, the system achieves accurate connection differentiation through a simple parameter comparison mechanism, avoiding complex signal processing while maintaining high measurement precision.
3Reliability
If restricted association is implemented for certain access points, then network security is improved, but ease of operation for mobile devices decreases
Solution Approach 1:
The patent introduces pilot identifiers as an intermediary mechanism that conveys access point type information to mobile devices. This intermediary allows restricted association to be implemented systematically through identifier-based classification, automatically managing security protocols without requiring complex manual configuration or reducing ease of operation for end users.

AI summary
Systems and methodologies are described that facilitate grouping pilot identifies to indicate type and/or classification information regarding one or more access points. The access points can select or be assigned pilot identifiers from the group indicating a type or classification related to the access points. Thus, identifiers can be grouped into macrocell and/or femtocell groups or ranges such that an access point can indicate, and mobile devices can efficiently determine, whether the access point provides macrocell or femtocell coverage based on a range from which its pilot identifier is selected or assigned. In addition, the pilot identifiers can be utilized to indicate restricted association information regarding the access points.
