Accelerated location information acquiring system and method

摘要

The present invention relates to a location information acquiring system developed to be used in professional trunked radio devices, comprising a global location data organization unit (4) wherein the locations of the subscribers can be acquired one after another sending location queries to a plurality of radios at the same time, which makes channel use more efficient, which can perform global location data transmission swiftly, which is in communication with the wireless communication unit (5), and which is adapted such that it will perform location queries to a plurality of subscriber radios (2) at the same time and acquiring the location information of the said radios (2), a global location data transmission unit (8) which is adapted such that it will perform the transmission of location information when it is radio's (2) turn, and a timer (14); and a method comprising the steps of sending, receiving query, and sending location information with timing.

主权项

1. A location information acquiring system, comprising
at least one main communication unit which realizes wireless digital data communication through at least one channel, has at least one wireless communication unit connected to at least one wireless communication antenna, at least one subscriber radio which has at least one communication unit and at least one global location receiver that is in communication with the main communication unit through the communication unit and that acquires current location information, at least one repeater which is adapted such that they will correct timing errors that can occur by updating the subscriber radios location information sending timings in the query message reaching to itself by subtracting its own delays from the recorded time in the message, repeats signals it receives and enables the main communication unit to communicate with a subscriber radio that is out of range, at least one global location data organization unit which communicates with the wireless communication unit, and the at least one global location data organization unit is adapted to send location queries to more than one subscriber radio at the same time and to acquire the location information of the subscriber radios one by one, and the at least one global location data organization unit is adapted such that it will perform location information communication through the wireless communication unit in a case there is no dedicated channel for global location communication and perform location information communication through a dedicated located data channel directly without using the wireless communication unit; at least one global location data transmission unit which is adapted to perform location information transmission process when subscriber radio's turn comes and receive the location queries from the global location receiver, and at least one timer that is in connection with global location data transmission unit and can follow an adjusted time of subscriber radio's turn, and adapted such that it will start the transmission of location data triggering the global location data transmission unit when the time it is adjusted is over.
