Abstract
Embodiments of the present invention provide an information transmission method, a radio equipment controller, a radio equipment, and a base station. The method includes determining, by an REC, that a main line used for communication with a first radio equipment RE is faulty and determining, by the REC, a standby line used for communication with the first RE. The method also includes communicating with the first RE by using the standby line.
Claims15
A radio equipment controller (REC), comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing a program for execution by the processor, the program including instructions to:
- send, through a power cable port or through a common public radio interface (CPRI) port, an addressing request message specific to a first radio equipment (RE);
- receive at least one addressing response message from the first RE;
- determine that a main line used by the REC to communicate with the first RE is faulty according to a path of an addressing response message sent by the first RE;
- determine a standby line used by the REC to communicate with the first RE according to the path of the at least one addressing response message;
- and
- communicate with the first RE using the standby line;
- wherein the main line is a common public radio interface (CPRI) communications line, and wherein the standby line is a power cable line or a power cable plus CPRI communications line.

A radio equipment (RE), comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing a program for execution by the processor, the program including instructions to:
- receive, through a first port, an addressing request message sent by a radio equipment controller (REC), wherein the first port is an uplink common public radio interface (CPRI) port or a power cable port;
- determine, according to the addressing request message, that an object that the addressing request message is specific to comprises the RE;
- send a first addressing response message to the REC through the first port and with a path indicating whether a main line of the RE is faulty;
- and
- determine, according to the addressing request message, that the object that the addressing request message is specific to further comprises another RE;
- and
- forward, through a downlink CPRI port and a power cable port, the addressing request message, in response to the first port being the CPRI port and further in response to determining, according to the addressing request message, that the object to which the addressing request message is specific further comprises another RE.
