Random access signalling sending method and apparatus

A random access signalling sending method and apparatus. The method comprises: according to a scenario for sending random access signalling and/or an attribute of a second-type node, determining at least one of the following parameters: a parameter of the random access signalling and a parameter of a random access channel used for sending the random access signalling; and sending, by the second-type node, the random access signalling on the random access channel according to the determined parameter. The technical solution of the present invention can effectively reduce overheads when a system is accessed.
