WISPGate Mobile / 3GPP (LTE Core Integration)

Unified BSS/OSS for MNO, MVNO & Private LTE Operators.

Book Demo All Features
WISPGate extends beyond traditional ISP environments into full 3GPP-compliant LTE ecosystems, providing deep integration between billing, CRM, OSS, and mobile core network components. It supports a wide range of LTE vendors and actively powers dozens of LTE operators across various regions.
Unlike generic billing platforms, WISPGate integrates directly with mobile core elements using Diameter-based signaling and policy enforcement mechanisms, enabling real-time subscriber authentication, quota control, charging synchronization, and SIM lifecycle management.

WISPGate (BSS / Billing / CRM / OSS)
WISPGate operates at the BSS/OSS layer while synchronizing policy and subscriber states with mobile core components.

Core Capabilities

Subscriber Management (SIM-Based)

WISPGate manages:

  • SIM lifecycle: Stock → Assigned → Activated → Suspended → Retired
  • IMSI mapping
  • MSISDN assignment
  • Data plan allocation
  • Subscriber profile configuration
  • Quota and usage tracking

SIM records are linked to:

  • Subscriber
  • Sub-Service
  • Device
  • Billing profile

Diameter-Based Integration

WISPGate integrates with LTE core components via Diameter protocols.

Typical Interfaces

  • HSS synchronization
  • PCRF policy control
  • Online charging interactions (architecture dependent)

Policy & Charging Control

WISPGate synchronizes:

  • Data plan limits
  • Speed profiles
  • Fair usage policies
  • Quota exhaustion handling
  • Suspension triggers
  • Real-time charging events (architecture dependent)

Policy Enforcement Model

Billing Rule Defined in WISPGate
↓
Subscriber Activated
↓
Policy Profile Generated
↓
Sent to PCRF
↓
PCRF Enforces Speed / Quota

If:

  • Invoice overdue → Restriction policy pushed
  • Plan upgraded → New speed profile activated
  • Quota exhausted → Throttle or block applied
This ensures revenue protection at the network layer.

MNO / MVNO / Private LTE Scenarios

MNO Deployment

  • Direct integration with core network
  • Full SIM control
  • Direct policy enforcement
  • Billing + subscriber management centralized

MVNO Deployment

Host MNO Core
↓
MVNO Logical Layer
↓
WISPGate BSS/OSS

WISPGate handles

  • Subscriber provisioning
  • Plan configuration
  • Billing
  • CRM
  • Customer portal
  • SIM inventory
  • Reporting

— while leveraging host MNO core infrastructure.

Private LTE (Enterprise / Campus)

  • Closed user group management
  • Internal SIM provisioning
  • Enterprise billing
  • Usage monitoring
  • Policy segmentation per department

SIM & MSISDN Inventory Management

WISPGate supports structured mobile inventory control.

SIM Lifecycle Workflow

Add SIM Batch
↓
Stock Inventory
↓
Assign to Subscriber
↓
Activate in Core
↓
Bind to Sub-Service
↓
Monitor Usage
↓
Suspend / Replace / Retire

DID / MSISDN Management (VoLTE / Hybrid Deployments)

Add Number Range
↓
Reserve
↓
Assign to SIM
↓
Bind to Subscriber
↓
Activate Routing
This ensures number and SIM governance.

Usage & Billing Synchronization

Usage data can be:

  • Periodically synchronized
  • Real-time event-driven
  • Batch-based depending on core architecture

Billing Synchronization Model

Usage Generated in Core
↓
Accounting Record
↓

Billing Engine Adjusted

Quota exhaustion logic:

  • Block
  • Throttle
  • Auto top-up (if configured)
  • Notification trigger

Integration with Existing Modules

The mobile module integrates with:

  • Billing Engine (cycle / pro-rata / hybrid)
  • CRM
  • Wallet
  • Automation workflows
  • Notification engine
  • Inventory (SIM / DID)
  • AAA (for hybrid fixed-wireless model)
This enables unified fixed + mobile operators on a single platform.

Hybrid Operator Model (Fixed + LTE)

Hybrid Operator Model (Fixed + LTE)

Subscriber
   ├── Sub-Service A (Fiber Internet)
   ├── Sub-Service B (LTE Backup SIM)
   └── Sub-Service C (VoIP)

Billing can:

  • Merge invoices
  • Separate by service
  • Apply different policy rules

Operators can offer:

  • LTE backup for fiber
  • Mobile + fixed bundles
  • Enterprise hybrid connectivity

Security & Compliance

WISPGate mobile architecture supports:

  • Secure Diameter signaling
  • Encrypted communication
  • Role-based SIM control
  • Audit logs
  • SIM activation traceability
  • Usage record integrity

Sensitive mobile core credentials remain protected within the network domain. WISPGate handles the BSS/OSS layer without exposing core infrastructure access.

Strategic Positioning

Most LTE vendors offer:

  • Core network tools
  • Limited billing
  • Weak CRM
  • No cross-module automation
  • No unified fixed-mobile model

WISPGate offers:

  • ✔ Full BSS/OSS integration
  • ✔ Diameter-based synchronization
  • ✔ SIM & MSISDN lifecycle control
  • ✔ Real-time policy enforcement
  • ✔ Unified fixed + mobile billing
  • ✔ MVNO-ready architecture
  • ✔ Workflow-driven automation
  • ✔ Hybrid service bundling

Business Impact

For LTE operators, this means:

  • Faster SIM activation
  • Real-time quota enforcement
  • Revenue protection
  • Reduced operational friction
  • Unified service portfolio
  • Scalable MVNO model
  • Clean separation between network core and business layer

WISPGate transforms LTE management from isolated core provisioning into a fully synchronized commercial + operational ecosystem.
