A method of controlling information requests in a communication system operating in an unauthorised, un-associated mode. e.g. IEEE 802.11 generic advertisement service (GAS) or UMTS home base station or Node B. The system comprises at least one user device 5a, 5b, 5c and an access point 6. The access point 6 receives a first information request from a user device 5a, 5b, 5c, along with a user device identifier, and sets a utilisation indicator. The access point 6 then receives a second information request from a user device 5a, 5b, 5c and checks to determine whether a timer associated with the utilisation indicator has expired. If so, the second information request is processed for response. The utilisation indicator is set according to the degree of congestion so that a user only gets a response to one request within a set time. The utilisation indicator may comprise a timer comprising a GAS traffic indication map (GASTIM) or a GAS comeback delay. |
