Nokia (Alcatel-Lucent) 3HE04790AA Mobile Gateway Integrated Services Module (MG-ISM)

Product Overview

Key Specifications

Core Features

1. Carrier-Grade Mobile Gateway Functionality
   
   
   Delivers high-performance SGW/PGW functions for LTE EPC networks, enabling seamless 4G mobile data services, and backward-compatible with 3G GGSN for legacy network migration.
2. High-Speed Packet Processing
   
   
   Purpose-built multi-core processor architecture delivers line-rate 40G mobile packet processing, supporting high-density subscriber traffic and low-latency mobile data services.
3. Integrated Services Capability
   
   
   Combines routing, mobile gateway, and service processing functions on a single module, reducing network complexity and hardware footprint in mobile core networks.
4. Advanced Thermal Design
   
   
   Features large copper heat pipes and high-density aluminum fin heat sinks to ensure stable operation under full load in high-density data center environments.
5. Scalable Architecture
   
   
   Supports modular expansion, allowing network operators to scale mobile core capacity incrementally as subscriber demand grows.

Compatibility & Supported Equipment

Primary Compatibility

• Alcatel-Lucent 7750 SR Series Service Routers: 7750 SR-1, SR-2, SR-7, SR-12, SR-24 chassis
• Mobile Core Network Applications: 4G/LTE EPC SGW/PGW, 3G GGSN, mobile backhaul aggregation

Multi-Vendor Interoperability

Typical Applications

• 4G/LTE Mobile Core Networks: Deployed as SGW/PGW in operator EPC networks to manage mobile data traffic between radio access networks and the internet.
• 3G/4G Network Migration: Supports legacy GGSN functions for smooth migration from 3G to 4G mobile networks.
• Mobile Backhaul Aggregation: Aggregates mobile backhaul traffic in service provider core networks.
• Carrier-Grade Mobile Services: Enables high-speed mobile data, roaming, and value-added services for mobile subscribers.

Technical Notes

• MG-ISM Architecture: The Mobile Gateway ISM is a purpose-built line card that offloads mobile gateway processing from the main router CPU, delivering dedicated performance for mobile core workloads.
• Thermal Design: The large copper heat pipe cooling system is required to dissipate heat from the high-power multi-core processors, ensuring 24/7 carrier-grade reliability.
• Nokia/Alcatel-Lucent Continuity: This module was originally developed by Alcatel-Lucent, which was acquired by Nokia in 2016, and is now supported under the Nokia Networks product line.
