Problems solved by technology

For example, bandwidth allocation conflicts on CPRI links will cause the entire base station to fail to work normally and interrupt services in severe cases.
In the future era of BBCLOUD, this problem may be particularly prominent, because the number of RECs and REs in the same CPRI network will increase a lot, which will greatly increase the possibility of ring physical link connection errors during construction

Abstract

The embodiment of the invention discloses a method, device and system for interconnection error detection. A method for interconnection error detection, the method includes a first wireless equipment controller (REC) receiving a detection message of a sending port through its first port, and the first REC detects and determines that the port information in the detection message is consistent with When the port information of the peer port of the first port preset by the first REC is inconsistent, a connection error is determined. Using the method of this embodiment, the REC can automatically detect whether there is a connection error between the sending and receiving ports, thereby notifying the user in time, and improving the reliability of the network system. The embodiment of the invention also discloses an interconnection error detection device and system.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method, device and system for interconnection error detection. Background technique [0002] According to the common public radio interface protocol (Common Public Radio Interface, CPRI), the base station is divided into two parts: a radio equipment controller (Radio Equipment Controller, REC) and a radio equipment (Radio Equipment, RE). They are usually connected by cables or optical cables. CPRI allows multiple interconnection modes between REC and RE, including chain, ring, double star, tree, etc. [0003] Among the above interconnection types, load sharing type, ring type, and dual-star type, they all form a unique ring type physical link between multiple CPRI ports of RECs (including multiple RECs). In practical applications, which two CPRI ports of RECs and how many REs pass through to form a ring-shaped physical link are all planned ...
