Server-Based HLR Bypass for Wireless Network Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile network operators restrict users' freedom to choose the cheapest network for outgoing calls and internet access due to control over Home Location Registers (HLRs), limiting competition and user choice.
Innovation Solution
A wireless device connects to a server that manages call routing independently of the network operator's HLR, using various protocols like SMS or HTTP, allowing users to choose their network and route for calls and data transfers, and enabling multimedia communications without relying on traditional HLRs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network operators control HLR to manage subscribers, then network management and service delivery are ensured, but user freedom to choose cheapest networks is restricted
Solution Approach 1:
The patent extracts the HLR functionality from the traditional network operator control structure and relocates it to a server-based system. The wireless device sends communication data directly to a server that determines call routing, bypassing the need for the device to be registered in the network operator's HLR. This extraction of HLR functionality enables users to choose different networks for outgoing calls while maintaining network management capabilities.
Solution Approach 2:
The patent introduces a server as an intermediary between the wireless device and the network operator's HLR. The server receives communication data from the device, determines the appropriate call set-up route, and facilitates the connection without requiring traditional HLR registration. This intermediary enables user freedom while maintaining network control through alternative means.
2Adaptability or versatility
If HLR registration is required for service, then network operators maintain control over subscribers, but competition from lower cost services is blocked
Solution Approach 1:
The patent extracts the service assurance mechanism from HLR registration and implements it through server-based communication. The server receives communication data, validates the request, and ensures reliable service delivery through alternative means. This allows users to access services through multiple networks without compromising service reliability.
Solution Approach 2:
The patent implements a universal server-based system that can handle communications across multiple networks and protocols. The server can receive communication data through various means and route calls through different networks, providing multi-functional service assurance that works across network boundaries rather than being tied to a single operator's HLR.
3Adaptability or versatility
If operators restrict outgoing traffic to subscribed networks, then revenue control is maintained, but user ability to access any web server is limited
Solution Approach 1:
The patent uses a server as an intermediary that receives communication data from the wireless device and determines the optimal call set-up route. This intermediary enables users to access any web server through multiple networks while maintaining efficient call setup through automated server-based routing decisions, balancing user freedom with operational efficiency.

AI summary
A wireless device can initiate a network connection without using a network operator's home location register. The wireless device sends data to a server that defines a call request; and the server decides on the appropriate routing over all available networks for that call request. But, unlike a conventional HLR, the server can receive communications from the device using any one of several different protocols, and is not limited to the MAP (mobile application part) protocol. For example, the wireless device can use SMS or HTTP over the internet to communicate with the server. The server then determines the appropriate least cost routing.
