How to Configure GSM Network Elements for Inter-operator Handover Agreements

Configuring GSM network elements for inter-operator handover agreements involves establishing seamless connectivity between different mobile network operators (MNOs) to facilitate the transfer of mobile subscribers between their respective networks. Here's a step-by-step guide:

1. Interconnection Agreement:

   • Before configuring network elements, establish a formal interconnection agreement between the participating MNOs. This agreement outlines the terms, conditions, and technical specifications for inter-operator handover, including signaling protocols, routing policies, and financial settlements.

2. Network Planning:

   • Conduct network planning and optimization to ensure compatibility and interoperability between the GSM networks of the participating MNOs. Coordinate with network engineers and stakeholders to define coverage areas, frequency bands, and handover zones for seamless handover transitions.

3. Roaming Agreements:

   • Implement roaming agreements between the MNOs to enable subscribers to access services outside their home network coverage area. Define roaming tariffs, service levels, and billing arrangements for inbound and outbound roaming traffic.

4. Handover Protocols:

   • Configure handover protocols such as GSM Inter-Cell Handover (ICH), Inter-BSC Handover, and Inter-MSC Handover to facilitate the transfer of active calls and data sessions between adjacent cells, base stations, and mobile switching centers (MSCs) of different MNOs.

5. Neighbor List Configuration:

   • Define neighbor cell lists for handover candidates between adjacent cells belonging to different MNOs. Configure parameters such as signal strength thresholds, hysteresis values, and handover priority levels to optimize handover performance and minimize call drops.

6. Handover Triggering:

   • Configure handover triggering mechanisms based on predefined criteria such as signal quality, signal strength, and cell load conditions. Implement handover algorithms and policies to prioritize handover requests and ensure efficient utilization of network resources.

7. Core Network Integration:

   • Integrate the core network elements of the participating MNOs, including MSCs, Home Location Registers (HLRs), Visitor Location Registers (VLRs), and Authentication Centers (AuCs). Establish signaling links and protocols for exchanging subscriber data and authentication information during handover procedures.

8. Testing and Validation:

   • Conduct extensive testing and validation of inter-operator handover configurations in lab environments and live network trials. Perform test scenarios for handover initiation, execution, and completion under various network conditions and traffic loads.

9. Quality of Service (QoS) Monitoring:

   • Monitor and analyze the quality of service (QoS) parameters such as call setup success rate, call drop rate, handover success rate, and handover latency for inter-operator handover connections. Implement network performance monitoring tools and alarms to detect and resolve QoS issues promptly.

10. Documentation and Compliance:

    • Document the inter-operator handover configurations, network settings, and operational procedures in technical specifications and operational manuals. Ensure compliance with regulatory requirements, industry standards, and service level agreements (SLAs) governing inter-operator roaming and handover operations.

11. Continuous Improvement:

    • Continuously monitor, evaluate, and optimize inter-operator handover performance based on network performance metrics, subscriber feedback, and industry best practices. Implement software upgrades, capacity expansions, and network optimizations to enhance the reliability and efficiency of inter-operator handover operations over time.

By following these steps and best practices, mobile network operators can configure GSM network elements for inter-operator handover agreements to provide seamless connectivity and roaming services for subscribers across different networks.
