摘要

Methods of transmitting and receiving information in a telecommunications network are described, as well as a telecommunication network and apparatus for a telecommunication network. The method of transmitting comprises identifying (Sl) a message for transmission, the message selected from a plurality of predetermined messages; selecting (S2) a code combination from a set of codes combinations, each code combination corresponding to a predetermined message; encoding (S3) data with the selected code combination; and transmitting (S4) the encoded data. The method of receiving comprises receiving (S5) the signal comprising data encoded for transmission with the selected code combination; decoding (S6) the signal to retrieve unencoded data, the decoding comprising determining with which code combination selected from the set of code combinations the data is encoded, and decoding the data; and selecting (S7) the message for transmission from the plurality of predetermined messages, wherein the message is selected based on the code combination with which the data was encoded.
