Description

Service architecture base station

Technical Field

The present application relates to the field of communications, and in particular, to a serving infrastructure base station.

Background

A fifth generation (5th-generation, 5G) mobile communication network applies Software Defined Networking (SDN) and Network Function Virtualization (NFV) technologies, and thus, the decoupling of network functions and hardware systems is achieved. Based on the SDN/NFV technology, a core network introduces a service architecture design concept of the Internet and provides a service architecture based on the cloud native technology.

In order to adapt to the development of a 5G network, a Radio Access Network (RAN) proposes a distributed architecture base station based on a Central Unit (CU)/Distributed Unit (DU). Currently, CUs communicate with the core network in a point-to-point manner. To meet the requirements of disaster tolerance, reliability, load balancing, and the like, a CU is generally connected point-to-point with a plurality of access and mobility management function (AMF) network elements, and registers in a core network through the AMF network elements. In this connection mode, each time an AMF element is added or subtracted from the core network, the CU needs to be reconfigured or deleted manually. For example, when a certain AMF network element fails, the core network may restart the AMF network element or reconfigure an AMF network element for the CU by using manual operation. When CUs in the radio access network are increased, the AMF network elements also need to be manually configured for the increased CUs. Therefore, the existing CU and AMF network element configuration depends on manual operation, and has poor flexibility and expansibility of configuration and easy failure of configuration.

If the request exists, the AMF network element 2018 may invoke the CP function through the first interface 3011, and send the request information from the terminal to the CP through the first interface 3011 by using the HTTP protocol, so as to establish a connection between the AMF network element 2018 and the CP.
