Triggerless Mobile Location Routing via Network Element Interception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional location-based routing methods for telecommunications networks are inefficient for mobile subscribers, as they rely on triggers that are costly to provision and fail to accurately determine geographic location, especially in mobile scenarios where directory numbers remain constant across vast areas.
Innovation Solution
A triggerless mobile location-based routing system that uses a network element to receive call setup messages, retrieve stored location information, and perform screening or routing functions based on the mobile subscriber's location, eliminating the need for costly trigger provisioning and providing accurate geographic routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional triggered location-based routing is used, then routing function can be initiated, but provisioning cost increases significantly
Solution Approach 1:
The patent extracts the trigger function from traditional end offices and consolidates it into a dedicated triggerless screening service routing node. This separation allows the routing system to operate without requiring expensive trigger provisioning at multiple end offices, while still maintaining accurate location-based routing capabilities through centralized message interception and processing.
Solution Approach 2:
The patent introduces a triggerless screening service routing node as an intermediary component between the message processing platform and the network. This intermediary intercepts call setup messages, determines geographic location without triggers, and routes calls appropriately, eliminating the need for costly trigger-based systems while preserving routing accuracy.
2Productivity
If directory number is used to indicate geographic location, then wireline routing works, but mobile subscriber location cannot be determined accurately
Solution Approach 1:
The patent performs preliminary actions by intercepting and processing call setup messages before call routing decisions are made. The triggerless screening service routing node proactively determines the geographic location of mobile subscribers by analyzing message content and routing calls accordingly, rather than relying on static directory numbers that cannot provide accurate mobile location information.
Solution Approach 2:
The patent changes the parameter used for location determination from static directory numbers to dynamic message-based location information. By analyzing call setup messages and extracting geographic location data therefrom, the system can accurately determine mobile subscriber locations regardless of their movement, enabling precise location-based routing for mobile devices.
3Reliability
If trigger-based location-based routing is implemented, then routing can be performed, but system complexity and provisioning requirements increase
Solution Approach 1:
The patent extracts the complex trigger provisioning requirements from the overall routing system and consolidates location determination functionality into a dedicated triggerless screening service routing node. This simplifies the overall system architecture by eliminating the need for triggers at multiple end offices while maintaining reliable location-based routing through centralized message interception and processing.

AI summary
Methods, systems, and computer readable media for performing triggerless mobile location-based screening and routing are disclosed. According to one aspect, the subject matter described herein includes a method for performing triggerless mobile location-based screening and routing. A telecommunications network element receives a mobility management message associated with a mobile subscriber, extracts from the mobility management message information identifying the mobile subscriber and location information associated with the mobile subscriber, and stores the extracted location information associated with the mobile subscriber. The network element receives a call setup message associated with a call from the mobile subscriber, extracts from the call setup message information identifying the mobile subscriber, retrieves the stored location information associated with the mobile subscriber, and performs a screening or routing function based on the location information associated with the mobile subscriber.
