The present invention provides a method and system for transmitting and receiving data, and a method and device for processing message. In the method, a relay server receives an assignment request message from a first User Equipment (UE), wherein the assignment request message is used for obtaining, by the first UE, authorization from the relay server, and the authorization is used for permitting the first UE to transmit and/or receive data via the relay server; the relay server requests a service server to authenticate the first UE according to the assignment request message; in the case that the service server authenticates the first UE successfully, the relay server permits the first UE to transmit and/or receive data via the relay server. According to the technical solution provided by the present invention, the operation complexity of a user is reduced, and the deployment and application of the relay server is improved greatly. |
