Abstract:
A wireless transmitter adapted to transmit a modified transmission sequence to facilitate location by a Wireless Location System, wherein the modified transmission sequence comprises a message sent from the wireless transmitter using transmission parameters different from the normal transmission parameters broadcast on a forward control channel by base stations in a wireless communications system; and wherein the wireless transmitter is programmed to perform the following functions:receiving the normal transmission parameters from a base station; initiating a call when a user of the wireless transmitter dials a sequence of digits and presses a predefined button; comparing the dialed sequence of digits with one or more trigger events stored within the wireless transmitter; using the normal transmission parameters in making the call if the dialed sequence of digits do not match the trigger event; and using the modified transmission sequence if the dialed sequence of digits matches the trigger event.
