Problems solved by technology

In this way, once a fault occurs at any point in the communication line, it will cause the REC to fail to communicate with any RE after the fault point, and manual off-site processing is required, which will bring a large off-site maintenance cost and cause Increase service interruption time and affect user experience

Embodiment A

[0224] In this embodiment, the REC can scan all the controlled REs in real time, and determine the RE whose main line fails among all REs, and determine the backup line of the RE whose main line fails.

[0225] Optionally, the REC sends addressing request messages for all controlled REs through the CPRI port or through the power line port and the CPRI port; each RE sends an addressing request message through the first port after receiving the addressing request message through the first port. Address response message, the first port is the uplink CPRI port or power line port; REC determines the RE whose main line fails according to whether the path of the addressing response message sent by each RE includes the main line; At least one path for addressing the response message, identifying a backup line for communicating with the RE whose primary line failed.

[0226] Optionally, after receiving the addressing request message, each RE forwards the addressing request message thro...

Embodiment B

[0274] In this embodiment, the REC can judge whether the main line through which the REC communicates with the RE is faulty through the heartbeat between the REC and the RE. Specifically, the REC and the RE send heartbeat messages to each other through the main line. If the REC does not receive the heartbeat messages sent by the RE for a predetermined number of consecutive times, it is determined that the main line for communication between the REC and the RE is faulty.

[0275] Optionally, when the REC determines that the main line communicating with the first RE fails, the REC sends an addressing request message for the first RE through at least one of the power line port and the CPRI port;

[0276] Optionally, the first RE receives an addressing request message through a first port, and sends an addressing response message through a first port, where the first port is an uplink CPRI port or a power line port;

[0277] The REC determines the backup line for communicating wit...

Embodiment C

[0340] In this embodiment, the REC 200 can scan in real time (for example, periodically or in the initialization phase) the RE (the first RE) whose main line fails among all REs under control, and determine the backup line of the RE whose main line failed.

[0341] Optionally, as in Figure 7 As shown, the first determining unit 210 includes a first sending subunit 211, a first receiving subunit 212, and a first determining subunit 213; wherein, the first sending subunit 211 is used for: through a CPRI port or through a power line port and a CPRI The port is used to send an addressing request message for all controlled REs; the first receiving subunit 212 is configured to: receive an addressing response message from at least one RE, where at least one RE includes the first RE; the first determining subunit 213 Used for: when determining that the path of at least one addressing response message received by the first receiving subunit 212 from the first RE does not include the m...

Abstract

Embodiments of the present invention provide an information transmission method, a wireless device controller, a wireless device, and a base station. The method includes: the REC determines that a main line for communicating with the first wireless device RE is faulty; the REC determines a backup line for communicating with the first RE; and communicates with the first RE through the backup line. The embodiments of the present invention can save site maintenance costs, reduce service interruption events, and improve user experience.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to an information transmission method, a wireless device controller, a wireless device and a base station. Background technique [0002] The base station is divided into two parts: a radio equipment controller (Radio Equipment Controller, REC) and a radio equipment (Radio Equipment, RE). Optical fiber communication lines are usually used between them, and the connection method is cascade connection. In this way, once a fault occurs at any point in the communication line, it will cause the REC to fail to communicate with any RE after the fault point, and manual off-site processing is required, which will bring a large off-site maintenance cost and cause Increase service interruption time and affect user experience. Contents of the invention [0003] Embodiments of the present invention provide an information transmission method, a wireless device controller, a w...
