Hybrid Mobile Call Routing via Node Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Call routing in hybrid mobile networks, particularly for emergency services and location-based services, is complex due to the need for accurate location identification and network type differentiation, especially in WLAN hotspots where latitude and longitude information may not be readily available, and existing solutions are not suited for packet switched paradigms.
Innovation Solution
A method and system for call routing that allocates routing parameters based on node identifiers and network addresses, using a processor to determine the appropriate identifier for communication devices switching between different network types, ensuring accurate routing and location determination across traditional mobile, UMA, and VOIP networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If latitude and longitude information is used for call routing, then routing accuracy is improved, but device complexity and ease of operation deteriorate because WLAN hotspots may not have this information readily available and may be moved frequently
Solution Approach 1:
The patent uses node identifiers (such as MAC addresses) and network addresses (IP addresses) as substitutes for latitude and longitude information. These alternative identifiers serve as copies or representations that enable routing without requiring precise geographic coordinates, thereby simplifying the operation for WLAN hotspots that lack GPS capabilities or frequent mobility.
2Device complexity
If a unified routing methodology is used for both circuit switched and packet switched networks, then device complexity is reduced, but reliability deteriorates because existing solutions are not generally suitable for packet switched paradigms
Solution Approach 1:
The patent creates a universal routing methodology that functions across both circuit switched networks (traditional mobile networks like GSM, CDMA) and packet switched networks (VOIP, UMA). The same core process of allocating routing parameters based on node identifiers and network addresses applies to both paradigms, eliminating the need for separate routing systems while maintaining reliability through standardized procedures.
Solution Approach 2:
The patent adapts routing parameters to suit different network types by using appropriate identifiers (node identifiers for mobile networks, network addresses for packet switched networks) while maintaining a consistent routing allocation process. This allows the system to change parameters based on network context rather than changing the entire routing methodology.
3Reliability
If multiple routing allocation methods are used for different network types and scenarios, then routing reliability is improved, but device complexity increases due to the need to determine appropriate identifiers for various communication devices
Solution Approach 1:
The patent segments the routing allocation process into distinct pathways based on network type and device association status. The system divides the problem into manageable cases: (1) first network type allocations, (2) second network type with previously associated devices, (3) second network type with previously identified nodes, and (4) second network type with unidentified nodes. Each segment has its own specific allocation method, reducing overall complexity through structured division.
Solution Approach 2:
The patent introduces an intermediary routing allocation mechanism that sits between the communication device and the final routing destination. This intermediary system automatically determines the appropriate routing parameters based on network type and device association, mediating the complexity of multiple allocation methods and presenting a unified interface to both devices and networks.
