Method for accessing a communication network, association method, terminal, base station, and corresponding computer programs

A method for attachment of a terminal to a communication network, comprising:

• broadcasting system information by said network, the system information comprising an identification of at least one time-frequency resource capable of carrying a piece of information relative to a unique terminal identifier;
• verifying reception, on at least one of said time-frequency resources identified on the basis of said system information, called specific resource, of a first piece of information representative of a unique identifier of said terminal, carried by a request for access to said network;
• and
• in response to said first piece of information representative of a unique identifier of said terminal being received, transmitting to said terminal a response to said access request, carrying a second piece of information representative of the unique identifier of said terminal,
• wherein said verifying also verifies reception, on said specific resource or on at least one time-frequency resource capable of carrying a useful message, identified on the basis of said system information, of a useful message, and
• wherein the method comprises transmitting said useful message in response to said first piece of information representative of a unique identifier of said terminal and said useful message being received.

A terminal comprising:

• at least one processing unit configured to:
• receive system information broadcast by a communication network that the terminal desires to access, the system information comprising an identification of at least one time-frequency resource capable of carrying a piece of information relative to a unique terminal identifier;
• transmit to said network a request for access to said network, said access request carrying a first piece of information representative of a unique identifier of said terminal, transmitted on at least one of said time-frequency resources identified on the basis of said system information, called specific resource;
• and
• receive a response to said access request, the access of the terminal to said network being authorized in the case of reception of a response to said access request carrying a second piece of information representative of the unique identifier of said terminal,
• wherein said access request also carries a useful message transmitted on said specific resource or on at least one time-frequency resource capable of carrying a useful message, identified on the basis of said system information.

A base station of a communication network, comprising:

• at least one processing unit configured to:
• broadcast system information comprising an identification of at least one time-frequency resource capable of carrying a piece of information relative to a unique terminal identifier;
• verify the reception, on at least one of said time-frequency resources identified on the basis of said system information, called specific resource, of a first piece of information representative of a unique identifier of said terminal, carried by a request for access to said network;
• transmit to said terminal a response to said access request carrying a second piece of information representative of the unique identifier of said terminal, if said first piece of information representative of an identifier of said terminal is received;
• verify a reception, on said specific resource or on at least one time-frequency resource capable of carrying a useful message, identified on the basis of said system information, of a useful message;
• and
• transmit said useful message in response to said first piece of information representative of the unique identifier of said terminal and said useful message being received.

A non-transitory computer-readable medium comprising a computer program stored thereon including instructions for implementing a method for accessing a communication network when this program is executed by a processor of a terminal, wherein the method comprises:

• receiving system information broadcast by said network, the system information comprising an identification of at least one time-frequency resource capable of carrying a piece of information relative to a unique terminal identifier;
• transmitting to said network an access request, said access request carrying a first piece of information representative of a unique identifier of said terminal, transmitted on at least one of said time-frequency resources identified on the basis of said system information, called specific resource;
• and
• authorizing access to said network in the case of reception of a response to said access request carrying a second piece of information representative of the unique identifier of said terminal,
• wherein said access request also carries a useful message transmitted on said specific resource or on at least one time-frequency resource capable of carrying a useful message, identified on the basis of said system information.
