2106570 9217964 PCTABS00016 The invention relates to a method of controlling the operation of a packet switched CDMA telecommunication network, wherein N network users are connected to the network by respective terminals, and the terminal of each user is assigned an orthogonal receiver code. To improve the properties of the packet network, the network terminal wanting to transmit senses the channel forming the transmission path for the presence of the receiver code of the other communicating party, i.e. the receiving terminal, in signals transmitted by the other terminals, said receiving terminal being the terminal to which the sensing terminal wants to transmit data in packet format. If the receiver code is not detected in the channel, said terminal wanting to transmit initiates the transmission of packet-format data encoded by said receiver code, whereas if the receiver code is detected in the channel, said terminal wanting to transmit remains waiting so as to repeat the above-described sensing algorithm after a period of time.
