Description

Network node configuration method and device

Technical field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for configuring a network node.

Background technique

With the continuous evolution of wireless communication technologies and protocol standards, the mobile packet service has undergone tremendous development, and the data throughput capability of a single terminal has been continuously improved. For example, the Long Term Evolution (LTE) system can support data transmission with a maximum downlink rate of 100 Mbps in a 20 M bandwidth. In subsequent LTE enhanced systems and subsequent 5G systems, the data transmission rate will be further improved. Even tens of Gbps can be reached.

The inflated growth of terminal data traffic has put tremendous pressure and challenge on the service capabilities and deployment strategies of mobile networks. On the one hand, operators need to enhance existing network deployment and communication technologies. On the other hand, they hope to accelerate the promotion of new technologies and network expansion, so as to achieve the goal of rapidly improving network performance. Since the development of mobile communication systems, it has become more and more difficult to provide economical, flexible, and high-capacity services only by enhancing the macro network. Therefore, it is necessary to introduce ultra-dense and flexible small-base station deployment. The deployment of ultra-dense small base stations is bound to bring frequent inter-station handover and signal interference problems, and the above problems will lead to the development of network architecture to C/U separation and control concentration. In recent years, C-RAN (Centralized, Cooperative, Cloud & Clean-Radio Access Network) networks with centralized baseband units (BBUs) and Radio Remote Units (RRUs) have been deployed in many places around the world. Countries and regions have been used more and more widely. In the existing architecture, the pre-transmission interface between the BBU and the RRU uses a Common Public Radio Interface (CPRI) interface. Since the CPRI interface transmits IQ signals processed by physical layer coding and modulation, the CPRI interface has large requirements on transmission delay and bandwidth. Especially when the air interface rate is increased to tens of Gbps, the traffic demand of the CPRI interface will rise to the Tbps level, which brings great pressure on the network deployment cost and deployment difficulty. However, for the above problems in the related art, there is currently no effective solution.

In the configuration process of the network node in the embodiment of the present invention, the first network node receives configuration information sent by the second network node through the first interface, and then configures a function set of the functions supported by the second network node according to the configuration information, and/or configures Configuration information of the second interface between the first network node and the second network node, and/or configuration information of the second interface between the first network node and the third network node, where the first interface is a control plane The interface and the second interface are the user plane interfaces. It can be seen that, in this embodiment, the network nodes can be configured according to different interfaces, thereby solving the related technology, because the CPRI interface has a large delay and bandwidth during transmission. The requirements have led to tremendous pressure on the service capabilities and deployment strategies of mobile networks.
