The present disclosure relates to the field of mobile communication technologies, and provides a method for locating operation nodes in a communication system. The method includes using an identifier in the received message to obtain an adjusted path from the root node of the management tree of the client to the standard management object corresponding to the identifier, using the message to obtain a relative path between the target operation node and the root node of the standard management object on the management tree, concatenating the adjusted path with the relative path, and locating the target operation node according to the concatenated path. The present disclosure also provides a system for locating operation nodes, a client for locating operation nodes in a communication system, and a server for performing management operations for clients.
