Methods of transmitting and receiving information in a telecommunications network are described. A method of transmitting, for example, includes identifying a message for transmission, the message selected from a plurality of predetermined messages, and selecting a code combination from a set of codes combinations, each code combination corresponding to a predetermined message. Data is encoded with the selected code combination, and the encoded data is transmitted. A method of receiving may include receiving the signal including data encoded for transmission with the selected code combination, and decoding the signal to retrieve unencoded data, the decoding including determining with which code combination selected from the set of code combinations the data is encoded. The data is decoded, and the message for transmission is selected from the plurality of predetermined messages, wherein the message is selected based on the code combination with which the data was encoded.
