Description

Method and device for QoS management

Technical field

The present invention relates to the field of mobile communications technologies, and in particular, to a QoS (Quality of Service) management method and apparatus.

Background technique

Mobile communications have developed rapidly over the past 20 years, and have had a tremendous impact on people's lifestyles, working methods, and political and economic aspects of society. Human society has entered an era of efficient informationization, and the demand for business applications in all aspects has exploded, which will bring huge challenges to the future wireless mobile bandwidth system in terms of frequency, technology and operation. The 5G mobile broadband system will become a wireless mobile communication system for the needs of the human information society after 2020. It is a multi-service and multi-technology convergence network. Through the evolution and innovation of technology, it can meet a wide range of data and connections in the future. The need for development to enhance the user experience.

With the increase of the bandwidth and capabilities of wireless mobile communication systems, the mobile Internet and Internet of Things applications for individuals and industries are developing rapidly, and the ecology of mobile communication related industries will undergo important changes. Wireless mobile communication technology and computer and information technology will be more closely and deeper cross-integration, integrated circuits, device technology, software technology, etc. will continue to develop rapidly, supporting the future development of 5G mobile broadband industry. According to social responsibilities and functions, end users, business applications and network operations, the future 5G vision analysis, from the technical point of view to summarize the key capability requirements of 5G are as follows:

1000 times of traffic growth, unit area throughput increased significantly: Based on the growth trend of data traffic in mobile communication networks in recent years, the industry predicts that by 2020, the total global mobile data traffic will reach 1000 times of the total mobile data traffic in 2010. This requires a throughput capacity per unit area, especially in the busy hour throughput capacity, which is also 1000 times higher and needs to reach 100 Gbps/km2 or more.

100 times the number of connected devices: In the future, the 5G network users will expand greatly. With the rapid development of the Internet of Things, the industry expects that the number of connected devices will reach 50-100 billion by 2020. This The number of devices supported in a unit coverage area will increase greatly. In some scenarios, the number of devices connected by a 5G mobile network per unit area reaches 1 million/km2, which is 100 times larger than that of 4G.

Smaller latency and higher reliability: 5G networks need to provide users with an always-on experience and meet more high-value scenarios such as industrial control, emergency communications and more. This aspect requires further reduction in user face delay and control plane delay, which is 5-10 times shorter than 4G, reaching the limit of human response such as 5ms (tactile response) and providing a true always-on experience. On the other hand, some businesses that are related to people's lives and major property security require end-to-end reliability to be increased to 99.999% or even 100%.

The existing 4G evolved Evolved Packet System (EPS) QoS (Quality of Service) management architecture, as shown in Figure 1: The existing quality (QoS) management control is mainly composed of nodes such as terminals, base stations, and packet gateways. Controlling, the QoS parameters signed by the user are transmitted by the control network element Mobility Management Entity (MME) to the terminal, the base station, and the packet gateway through control plane signaling. This processing mechanism mainly has the following problems:

There is no end-to-end QoS guarantee service between the terminal and the server. As shown in Figure 1, the transmission network between the base station and the packet gateway, and the gateway and the external server do not achieve perfect QoS guarantee;

In addition, in order to implement QoS management, the UE, the base station, and the packet gateway forwarding plane device need to establish a bearer connection and save the state information of the bearer, which increases the complexity of the forwarding device and may eventually affect the forwarding performance of the forwarding device.
