Location-Based Call Forwarding Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional call forwarding systems in wireless telecommunications networks are location-independent, requiring subscribers to manually change call forwarding numbers and voicemail greetings based on their current location, which is inefficient and burdensome, especially for users with multiple locations.
Innovation Solution
The technology implements location-specific call forwarding procedures by using the current location information of a wireless device, obtained during routine processes like registration, to dynamically update call forwarding information and voicemail greetings, allowing the network to automatically redirect calls and voicemails based on the subscriber's location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual call forwarding configuration is used, then users can control call routing, but user burden increases and efficiency decreases
Solution Approach 1:
The system automatically performs call forwarding configuration based on location information received during routine registration processes. The network autonomously updates call forwarding numbers and voicemail greetings without requiring user intervention, making the system self-configure based on detected location changes.
Solution Approach 2:
Location-specific call forwarding information is pre-configured in the network database associated with different location identifiers. When the system detects a location change during registration, it immediately retrieves and applies the pre-prepared call forwarding configuration for that location, eliminating the need for real-time manual setup.
2Extent of automation
If location tracking is implemented, then call forwarding can be automated, but privacy concerns arise
Solution Approach 1:
The system combines location tracking with existing routine network registration processes. Location information is obtained as a byproduct of normal network operations rather than through separate tracking mechanisms, reducing privacy intrusion while enabling automated call forwarding based on the user's current location.
3Use of energy by moving object
If location information is obtained during routine processes, then device resources are conserved, but location accuracy may be limited
Solution Approach 1:
The system uses location identifiers (such as cell tower IDs or area codes) obtained during routine registration as proxies for precise geographic location. These identifier copies are sufficient to distinguish between different locations for call forwarding purposes without requiring continuous access to high-precision GPS data, thereby conserving device resources.

AI summary
A wireless telecommunications system provides location-specific call forwarding. The system can receive a request to connect a voice call to the wireless device, which can invoke a call forwarding procedure depending on a status of a subscriber associated with the wireless device. When the system determines that a current location of the wireless device is different from a default location, location-specific call forwarding information is used to forward the voice call to a terminating node associated with the location-specific forwarding information rather than a default terminating node for the default location. The terminating node can include a voicemail server that plays back a location-specific voicemail greeting to the caller.
