Abstract
Signalling information is conveyed from a transmitting device (101) to a receiving device (102) in a cellular radio network where user data transmission takes place on a traffic channel in discrete transmission bursts (111–120; 211–220; 310–313) consisting of consecutive symbols. A piece of signalling information is formatted into symbols which are transmitted as a block of consecutive symbols (FACCH) in a certain transmission burst of a traffic channel. It is also indicated within said certain transmission burst that it contains symbols carrying signalling information.

A method for conveying signalling information from a transmitting device to a receiving device in a cellular radio network where user data transmission takes place on a traffic channel in discrete transmission bursts consisting of consecutive symbols, comprising the steps of:
- formatting a piece of signalling information into symbols,
- transmitting the symbols carrying the signalling information as a block of consecutive symbols in a certain transmission burst of a traffic channel and
- indicating within said certain transmission burst that it contains symbols carrying signalling information.
A transmitting device for transmitting signalling information to a receiving device in a cellular radio network over a traffic channel in discrete transmission bursts consisting of consecutive symbols, comprising:
- means for formatting a piece of signalling information into symbols,
- means for transmitting the symbols carrying the signalling information as a block of consecutive symbols in a certain transmission burst of a traffic channel and
- means for indicating within said certain transmission burst that it contains symbols carrying signalling information.
