A method comprising: configuring an ad-hoc mode for a first mobile station "MS" (150i,... 150N) operating in an ad-hoc network under a broadband wireless standard, wherein configuring the ad-hoc mode comprises configuring ad-hoc mode parameters including an identifier for distinguishing the ad-hoc network from an infrastructure network under the broadband wireless standard, the ad-hoc mode parameters including at least one of a MS name, an operational mode, an encryption key, and a frequency channel, the operational mode being one of a MS mode, a serving MS, "SMS" mode, and an automatic mode; acquiring an ad-hoc mode communication having a simplified communication protocol of the broadband wireless standard; characterised by communicating with a second MS (150i,... 150N) using the ad-hoc mode communication, wherein acquiring the ad-hoc mode communication comprises: if the operational mode is the automatic mode or the MS mode, searching for SMS during a search period, if at least an SMS is found, displaying the at least found SMS, allowing user to select an SMS to connect to, and starting the ad-hoc mode communication with the selected SMS; else if the operational mode is the automatic mode, setting the operational mode as the SMS mode searching for an available frequency channel, and starting the ad-hoc mode communication as an ad-hoc SMS; and if the operational mode is the SMS mode, searching for an available frequency channel, and starting the ad-hoc mode communication as an ad-hoc SMS. configuring an ad-hoc mode for a first mobile station "MS" (150i,... 150N) operating in an ad-hoc network under a broadband wireless standard, wherein configuring the ad-hoc mode comprises configuring ad-hoc mode parameters including an identifier for distinguishing the ad-hoc network from an infrastructure network under the broadband wireless standard, the ad-hoc mode parameters including at least one of a MS name, an operational mode, an encryption key, and a frequency channel, the operational mode being one of a MS mode, a serving MS, "SMS" mode, and an automatic mode; acquiring an ad-hoc mode communication having a simplified communication protocol of the broadband wireless standard; characterised by communicating with a second MS (150i,... 150N) using the ad-hoc mode communication, wherein acquiring the ad-hoc mode communication comprises: if the operational mode is the automatic mode or the MS mode, searching for SMS during a search period, if at least an SMS is found, displaying the at least found SMS, allowing user to select an SMS to connect to, and starting the ad-hoc mode communication with the selected SMS; else if the operational mode is the automatic mode, setting the operational mode as the SMS mode searching for an available frequency channel, and starting the ad-hoc mode communication as an ad-hoc SMS; and if the operational mode is the SMS mode, searching for an available frequency channel, and starting the ad-hoc mode communication as an ad-hoc SMS. if the operational mode is the automatic mode or the MS mode, searching for SMS during a search period, if at least an SMS is found, displaying the at least found SMS, allowing user to select an SMS to connect to, and starting the ad-hoc mode communication with the selected SMS; else if the operational mode is the automatic mode, setting the operational mode as the SMS mode searching for an available frequency channel, and starting the ad-hoc mode communication as an ad-hoc SMS; and searching for SMS during a search period, if at least an SMS is found, displaying the at least found SMS, allowing user to select an SMS to connect to, and starting the ad-hoc mode communication with the selected SMS; displaying the at least found SMS, allowing user to select an SMS to connect to, and starting the ad-hoc mode communication with the selected SMS; else if the operational mode is the automatic mode, setting the operational mode as the SMS mode searching for an available frequency channel, and starting the ad-hoc mode communication as an ad-hoc SMS; and setting the operational mode as the SMS mode searching for an available frequency channel, and starting the ad-hoc mode communication as an ad-hoc SMS; and if the operational mode is the SMS mode, searching for an available frequency channel, and starting the ad-hoc mode communication as an ad-hoc SMS. searching for an available frequency channel, and starting the ad-hoc mode communication as an ad-hoc SMS.
