Abstract

The embodiment of the invention provides a system architecture based on a centralized base station control plane, and the system architecture comprises a coordination control module which is used forcarrying out the capacity expansion of a cell in a server or between servers, a protocol processing module which is used for receiving and / or forwarding the standard interface message and encoding and / or decoding the standard interface message, an algorithm processing module which is used for carrying out calculation processing on a protocol algorithm and a base station optimization algorithm, a process control module which is used for controlling a cell process, a paging process, an access process, a context management process and a bottom layer parameter configuration process, a public support module which is used for providing a public call function, a log record, timer maintenance, message transceiving and information query, and a scene selection module which is used for judging whether the current system architecture is a centralized scene or a separated scene, and selecting a corresponding scene strategy based on the judged scene. The embodiment of the invention provides a new system architecture which is universally used for CU and DU network elements.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a system architecture based on a centralized base station control plane. Background technique [0002] With the continuous evolution of wireless communication technology and the rapid development of 5G technology, the cloudification of communication equipment is valued by operators. The main role of cloudification is to reduce operating costs, enhance the versatility of hardware equipment and more flexible configuration according to scenarios Therefore, for the base station side, how to be able to flexibly load and configure different network elements of the access network, and at the same time provide relatively optimal performance in different scenarios, is a very severe test for the implementation architecture of the base station. [0003] The CU (Centralized Unit)-DU (Distributed Unit) separation architecture is a new architecture based on flexible configuration c...
