[Barcelona, Spain, Feb.26, 2017] On the day before Mobile World Congress (MWC) in Barcelona, Huawei releases the world's first 5G core solution for commercial use case, known as Service-Oriented Core 2.0 (SOC 2.0). At the 2016 MWC, Huawei introduced the world's first 5G core prototype, known as SOC 1.0, and verified its multi-service slicing technology. SOC 2.0 will show the commercial 5G capabilities of the solution and enable all access to 5G networks and all services in 5G. It will not only provide connectivity for a multitude of terminals from various industries, but also on-demand services for all vertical industries.

In the 5G era, telecom networks will not only provide users with communication services, but also information connectivity and services for various industries, such as autonomous driving, industrial controlling, and AR/VR. With the growing variety of access modes and diverse and complicated services, a core network that will support all access and all services is required.

SOC 2.0 will help operators enable all access and all services and obtain 5G commercial success through driving the transformation of telecom networks in the following ways:

• Drive the network to the transformation of distributed architecture. 5G networks will be distributed on demand. Through C/U separation, network user planes can be deployed to the network edge according to the service requirements.
• Drive network functions to the transformation of on-demand services. All services and all access will require highly diversified network capabilities; therefore, it is necessary to decouple network elements according to their functions and to form independent and modularized functions. Through on-demand service methods, these functions are organized in the unified architecture according to the service requirements. Multiple access modes and service requirements are agilely supported. Every function can be independently iterated and updated to quickly meet new service requirements.
• Intelligently distribute service-oriented channel resources and capabilities. It is difficult to meet all the service requirements on one network because of multiple services. Networks should be organized into isolated channels according to the service requirements to provide every vertical industry with services respectively. Technically, it can be achieved by building dedicated bearers for different services or through network slicing.

According to the service development and progress in technologies and standards, SOC will help operators to gradually build a 5G core network in three stages.

In the first stage, reconstruct the infrastructure with cloud and SDN technology, and build a DC-centered network cloud platform.

In the second stage, deploy VNFs based on the cloud architecture to prepare for the smooth evolution in the next stage. The key technologies include C/U separation, cross-DC deployment, stateless design and more.

In the last stage, deploy a standardized 5G core network on the cloud-based network architecture to support 5G services.

Since 2009, Huawei has actively researched 5G technologies, actively invested in the technological innovation of 5G core networks, and engaged in driving the technology and standardization development of 5G core networks. Huawei has obtained key positions in the industry, including SA2 chairperson. We have also presented the largest number of 5G infrastructure proposals, the number of which is accepted most in the world. Huawei works closely with the world's leading operators, vertical industry partners and open source organizations, to better develop 5G core networks and better connect the world.

At the 2017 MWC, Huawei, Deutsche Telekom and Vodafone will jointly demonstrate 5G business scenarios based on SOC 2.0.
