Provided are a message transmission method, an access node, an access controller and an access system. In the method, messages are not processed by an access node, but rather by an access controller, so that it is not necessary for the access node to support a relay function, reducing operation and maintenance difficulties and costs. In the method, an access controller receives a first message sent by an access node, the first message comprising a first identifier; the access controller obtains a line identifier according to the first identifier; the access controller obtains a second message according to the line identifier, the second message comprising the line identifier; the access controller sends the second message to a relay server. |
