MOCN (Multi Operator Core Network)

Last updated on 

Multi Operator Core Network (MOCN) is a technology that allows multiple mobile network operators (MNOs) to share a single core network infrastructure. This approach enables MNOs to provide mobile services to their customers while reducing capital expenditures and operational costs, ultimately leading to improved network efficiencies and enhanced user experiences. In this article, we will explore the fundamentals of MOCN, its benefits, challenges, and use cases.

MOCN Fundamentals

The MOCN architecture is designed to enable multiple MNOs to share a single core network infrastructure. The core network infrastructure comprises network elements such as the Mobile Switching Center (MSC), Home Location Register (HLR), and Gateway GPRS Support Node (GGSN). These elements provide core network functionalities, such as call routing, authentication, and mobility management.

Traditionally, MNOs have had to invest heavily in building their own core network infrastructures, which can be expensive and time-consuming. With MOCN, MNOs can share a common core network, reducing capital expenditures and operational costs. Additionally, MOCN enables MNOs to rapidly deploy new services and features, reducing time-to-market.

MOCN can be implemented in two ways: soft MOCN and hard MOCN. Soft MOCN involves sharing the core network elements without physical separation, while hard MOCN involves physically separating the core network elements. Soft MOCN is the most common approach since it is easier to implement and manage.

MOCN Benefits

MOCN offers several benefits to MNOs, including:

  1. Reduced Capital Expenditures: MOCN enables MNOs to share a single core network infrastructure, reducing the capital expenditures required to build their own core network.
  2. Reduced Operational Costs: MOCN also reduces operational costs by enabling MNOs to share resources such as servers, storage, and network connectivity.
  3. Improved Network Efficiencies: Sharing a common core network infrastructure enables MNOs to optimize network resources, resulting in improved network efficiencies and better user experiences.
  4. Rapid Deployment of New Services and Features: MOCN enables MNOs to rapidly deploy new services and features, reducing time-to-market.
  5. Increased Network Capacity: MOCN allows MNOs to increase network capacity by sharing resources and optimizing network utilization.
  6. Enhanced Network Resilience: MOCN provides enhanced network resilience by allowing MNOs to share network resources and reduce single points of failure.

MOCN Challenges

MOCN also presents some challenges, including:

  1. Technical Complexity: Implementing MOCN requires a high level of technical expertise and coordination between MNOs.
  2. Regulatory Requirements: Some countries have regulatory requirements that limit or prohibit MOCN.
  3. Security Concerns: MOCN introduces additional security risks since multiple MNOs are sharing a common core network infrastructure.
  4. Inter-Operator Dependency: MOCN introduces inter-operator dependency, which can increase the complexity of network management and support.
  5. Interference: Sharing network resources can result in interference, which can impact network performance.

MOCN Use Cases

MOCN has several use cases, including:

  1. Rural Connectivity: MOCN can be used to provide mobile services in rural areas where deploying a standalone network infrastructure may not be financially viable.
  2. Network Sharing: MOCN can be used to share network resources in densely populated areas where network capacity may be limited.
  3. National Roaming: MOCN can be used to enable national roaming, allowing customers to use their mobile services across multiple networks.
  4. Emergency Communications: MOCN can be used to provide emergency communications services during disasters or other emergencies.
  5. Internet of Things (IoT: MOCN can be used to support IoT services, which often require low power consumption, high reliability, and extensive coverage.

Conclusion

Multi Operator Core Network (MOCN) is a technology that enables multiple MNOs to share a single core network infrastructure. This approach offers several benefits, including reduced capital expenditures, reduced operational costs, improved network efficiencies, rapid deployment of new services and features, increased network capacity, and enhanced network resilience. However, implementing MOCN can be technically complex, and there are regulatory, security, and interference concerns to consider. MOCN has several use cases, including rural connectivity, network sharing, national roaming, emergency communications, and IoT services. As mobile networks continue to evolve, MOCN is likely to play an increasingly important role in enabling MNOs to provide high-quality mobile services to their customers while reducing costs and improving network efficiencies.
