Modern applications increasingly rely on location awareness, but not every location use case is about knowing where a device is at a particular moment.
Many are about knowing when something changes.
Fleet management, logistics, regulated-zone compliance, smart cities, fraud prevention, and workforce safety all depend on detecting when a device enters or exits a defined geographic area. These are event-driven problems, yet they’re often solved using request-response APIs designed to answer only a single question:
“Where is the device right now?”
While effective for point-in-time queries, this approach forces applications to continuously poll the network in order to detect changes. As deployments scale, polling becomes inefficient, increases signaling traffic, and introduces unnecessary latency.
From Polling to Event-Driven Architecture
With CAMARA Geofencing Subscriptions, the execution model changes completely. Instead of repeatedly asking the network for a device’s location, an application creates a subscription that defines:
- the mobile subscriber
- the geographic boundary
- the events of interest (entry or exit)
Once registered, the mobile network continuously monitors that relationship and generates an event only when the boundary state changes. Rather than applications constantly asking if something has happened, the network simply notifies them when it does. The result is an event-driven architecture that is more scalable, more efficient, and better suited to production environments.
Key advantages include:
- Reduced signaling traffic
- Lower API utilization
- Faster boundary detection
- Simplified application logic
- Improved scalability for large deployments
Applications no longer need to determine polling intervals or compare previous and current locations. They simply respond to meaningful events.
Powered by Carrier-Grade Location Infrastructure
Within PAiCore’s Network API Gateway, Geofencing Subscriptions are delivered through integration with our carrier-grade Gateway Mobile Location Centre (GMLC).
The same trusted location infrastructure also powers:
- Location Retrieval
- Location Verification
- Geofencing Subscriptions
Rather than exposing proprietary interfaces, PAiCore presents these capabilities through standardized CAMARA-compliant Network APIs, allowing developers to consume advanced mobile network functions using modern REST APIs.
Part of the GSMA Open Gateway Ecosystem
PAiCore is committed to the industry’s move toward programmable mobile networks. Our Network API Gateway implements APIs aligned with the CAMARA Project and the GSMA Open Gateway initiative, enabling mobile operators to expose standardized network capabilities without vendor-specific integrations. This allows application developers to build once and integrate consistently across multiple operators, accelerating innovation while preserving interoperability.
Built on Open Source. Designed for Operators.
Open technologies have always been central to PAiCore’s engineering philosophy. Our Network API Gateway is built using open-source technologies and integrates seamlessly with existing telecom infrastructure. Whether operators are modernizing legacy networks or deploying next-generation programmable services, PAiCore provides a standards-based platform that bridges traditional telecom signaling with cloud-native APIs.
A Complete Portfolio of Network APIs
Geofencing Subscriptions are part of PAiCore’s growing Network API portfolio, which includes:
- Location Retrieval
- Location Verification
- Geofencing Subscriptions
- Number Verification
- Silent Authentication
Together, these APIs enable operators to expose secure, trusted network capabilities to enterprises and developers through a single CAMARA-compliant gateway.
As adoption of Network APIs continues to accelerate, PAiCore remains focused on delivering open, interoperable solutions that help operators participate in the evolving API economy while giving enterprises access to powerful network intelligence through familiar developer interfaces.
