Problems solved by technology

At the same time, the radio frequency unit (RU) based on MASSIVE MIMO technology often needs multiple network ports to support large bandwidth scenarios. If a single network port on the transmission synchronization plane (S-PLANE) loses connection, the entire device will not work normally. Therefore, there is an urgent need for a method for switching the synchronization plane between network ports on the radio frequency unit

Abstract

The invention provides a method for realizing switching of a synchronization surface between network ports on a radio frequency unit, and relates to the technical field of communication interfaces. The method comprises the steps: connecting a distribution unit and a radio frequency unit through an optical fiber by using an SFP interface; arranging a processor to monitor the Ethernet main body module; reading and writing a switch register; when it is monitored that the SFP interface is interrupted, inquiring the locking state of the network port; setting a first data stream selection switch and a second data stream selection switch; if only one network port is locked, configuring a switch register to send a control signal to a data stream selection switch, and switching a data path of the 1588 functional module to the network port for adaptation; if it is monitored that the plurality of network ports are locked, enabling the processor to configure a switch register to select and send a control signal to the data stream, and switching the data path of the 1588 function module to the network port with the smallest network port number. A single network port on a transmission synchronization surface can be prevented from being disconnected, and the normal work of the whole communication equipment is kept.

Description

technical field [0001] The invention relates to the technical field of communication interfaces, in particular to a method for realizing the switchability of a synchronization plane between network ports on a radio frequency unit. Background technique [0002] In 4G (LTE) communication technology, CPRI is usually used as the fronthaul interface, but with the maturity of 5G and OPEN RAN architecture, enhanced CPRI (ECPRI / Common Public Radio Interface) has replaced CPRI as the new fronthaul interface. Since the bottom layer of the ECPRI protocol is based on Ethernet (MAC layer or TCP / IP layer), the versatility and flexibility are greatly improved. In addition, standardizing the user plane, control plane, management plane, and synchronization plane protocols above the ECPRI protocol provides architectural guarantees for the interconnection and intercommunication of radio frequency units (RU) and distribution units (DU) of different manufacturers. The synchronization plane (S-P...
