How can LTE foster collaboration and integration among G network stakeholders?

1 5G network architecture

5G is not a single technology, but a combination of different network layers, domains, and services. It aims to provide enhanced mobile broadband, massive machine-type communication, and ultra-reliable low-latency communication. To achieve this, 5G relies on a flexible and scalable network architecture that can adapt to different use cases and scenarios. The 5G network architecture consists of three main components: the radio access network (RAN), the core network (CN), and the end-user devices.

2 LTE and RAN

The RAN is the part of the network that connects the end-user devices to the core network. It consists of base stations, antennas, and radio spectrum. The RAN is responsible for transmitting and receiving data and voice signals over the air interface. LTE is a technology that operates in the RAN and provides high-speed data and voice services. LTE can also support 5G services by using new radio spectrum bands, such as the millimeter wave, and by implementing advanced features, such as carrier aggregation, massive MIMO, and beamforming.

3 LTE and CN

The CN is the part of the network that provides the core functions and services, such as authentication, mobility management, session control, and service orchestration. The CN is also the interface between the RAN and the external networks, such as the internet, the cloud, or other operators. LTE has a specific CN architecture, called the Evolved Packet Core (EPC), that consists of four main elements: the Serving Gateway (S-GW), the Packet Data Network Gateway (P-GW), the Mobility Management Entity (MME), and the Home Subscriber Server (HSS).

4 5G and CN

5G introduces a new CN architecture, called the 5G Core (5GC), that is more modular, flexible, and cloud-native. The 5GC consists of several network functions (NFs) that can be deployed and scaled independently, depending on the service requirements. The 5GC also supports network slicing, which is the ability to create multiple virtual networks on the same physical infrastructure, each with its own characteristics and performance. The 5GC can coexist with the EPC and interwork with LTE and other access technologies.

5 Benefits of collaboration and integration

Collaboration and integration among 5G network stakeholders are essential for unlocking the full potential of 5G. By working together, operators, vendors, regulators, and customers can create a harmonized and interoperable 5G ecosystem. This collaboration can bring several advantages, such as faster and smoother deployment of 5G networks and services, reduced costs and complexity of network operations and maintenance, increased innovation and competition in the 5G market, improved customer experience and satisfaction, as well as enhanced security and privacy of 5G data and communications.

6 How to foster collaboration and integration

Fostering collaboration and integration among 5G network stakeholders can be achieved in several ways. Establishing common frameworks and guidelines for 5G network design, testing, and certification is one example. Additionally, sharing best practices and lessons learned from 5G trials and deployments can be beneficial. Participating in industry forums and associations that promote 5G standards and policies, developing partnerships and alliances that leverage complementary strengths, and engaging with customers and end-users to understand their needs are also effective strategies.
