A method for access to a communication network, implemented by a terminal. The method includes: receiving system information broadcast by the network, the system information including an identification of at least one time-frequency resource capable of carrying a piece of information relative to a unique terminal identifier; transmitting to the network an access request, the access request carrying a first piece of information representative of a unique identifier of the terminal, transmitted on one of the time-frequency resources identified on the basis of the system information, called specific resource; and authorizing access to the network in the case of reception of a response to the access request carrying a second piece of information representative of the unique identifier of the terminal.
