Definitions

  • This invention pertains to radios.
  • Two-way radios have a number of operating parameters including, but not limited to, transmitting power, operating frequencies (channel), operating band, modulation type, modulation index, frequency deviation, squelch setting, channel spacing, control channel (for trunked communications), noise blanker characteristic, and receive bandwidth.
  • operating parameters including, but not limited to, transmitting power, operating frequencies (channel), operating band, modulation type, modulation index, frequency deviation, squelch setting, channel spacing, control channel (for trunked communications), noise blanker characteristic, and receive bandwidth.
  • modulation type such as FM or AM
  • a parameter which is usually, but not always, variable is the operating frequency or
  • a significant factor in determining the current optimum operating parameters is the geographic location of the radio.
  • a particular radio As an example, a particular radio
  • radios For radios whose location is not fixed (that is, mobile), on the other hand, it is desirable for operating parameters to be adjusted whenever a change in the location of the radio causes the operating environment to change. For example, using our above example, if a mobile radio initially selects an operating frequency band and transmit power while it is located in downtown Los Angeles, the radio may need to periodically adjust (change) these frequency band and power settings as its location constantly changes during the course of its journey from the downtown area to a final destination of Death Valley. Moreover, it also may be advantageous to change other operating parameters during the course of such a journey.
  • a common control station uses a control channel to allocate the shared channels amongst the subscriber units.
  • a subscriber wishes to place a call, it first tunes to the control channel and transmits a channel request message to the control station.
  • the control station reserves, or assigns, an idle channel for the call.
  • the control station transmits the channel assignment information to the requesting subscriber via the control channel.
  • the requesting subscriber unit tunes to the assigned channel and proceeds to place its call.
  • trunked system A A possible scenario which might arise in such trunked systems is a mobile subscriber unit which travels in geographic region A served by trunked system A with associated control channel A, and which mobile subscriber unit also travels in region B served by trunked system B with associated control channel B.
  • trunked radio systems no convenient mechanism exists to allow the subscriber unit to easily and readily change from one trunked system to another when travelling in this way.
  • a method is provided, and an apparatus described, whereby one or more operating parameters of a mobile radio may be varied automatically, and without human intervention, based on the location of the radio.
  • Fig. 1 depicts the location-based adaptive radio control arrangement.
  • Fig. 2 depicts a flow diagram illustrating the steps of the invention.
  • the invention may be used with any location determining device or system (101), such as LORAN, satellite global positioning systems, or dead reckoning, and with any mobile radio having adjustable operating parameters.
  • location determining systems are well understood and need not be described here in any further detail.
  • mobile refers to a non-fixed location radio, and includes both vehicle mounted and personally carried radios.
  • the invention (100) is shown in Fig. 1.
  • Switch 1 (102) is arranged to select the operating frequency band of the radio. When switch 1 is in position designated “A”, the radio operates on the 800 MHz band (103). When switch 1 is in the position designated “B”, the radio operates on the 30 MHz band (104).
  • Switch 2 (105) is arranged to select the output power level of the transmitter. When switch 2 is in the position designated "A”, the output power is 10 Watts
  • Switch 3 (108) is arranged to select the control channel of the radio. When switch 3 is in the position designated "A", the control channel selected is channel A
  • the mobile radio (120) is equipped with a location determining device (101) which, in turn, is arranged to control the position of switch 1 (102), switch 2 (105), and switch 3 (108).
  • the location determining device (101) is capable of determining whether the radio is located in location A (the urban area) or location B (the rural area).
  • the location determining device (101) determines the radio is located in location A, it causes switch 1 (102) to reside in position "A", thereby causing the radio to operate on the 800 MHz band. Also when the location determining device (101) determines the radio is located in location A, it causes switch 2 (105) to reside in position "A", thereby causing the radio to transmit at 10 Watts power output. Finally, when the location determining device (101) determines the radio is located in location A, it causes switch 3 (108) to also reside in position "A", thereby causing the radio to use channel A as a control channel.
  • the location determining device (101) determines the radio is located in location B, it causes switch 1 (102) to reside in position "B", thereby causing the radio to operate on the 30 MHz band. Also when the location determining device (101) determines the radio is located in location B, it causes switch 2 (105) to reside in position "B”, thereby causing the radio to transmit at 100 Watts power output. Finally, when the location determining device (101) determines the radio is located in location B, it causes switch 3 (108) to reside in position "B", thereby causing the radio to use channel B as a oontrol channel.
  • Fig. 2 shows the flow diagram (200) of the steps of the invention.
  • the process starts with the radio determining its location (201). ⁇ f the radio determines it is located in a first predetermined location, such as location A (the urban area), the radio operates on the 800 MHz band
  • the radio determines it is located in location B (the rural area). If the radio determines it is located in location B (the rural area), the radio
  • the radio then returns (220) to its initial determining step (201), and makes a new determination of its location.

Abstract

L'invention concerne un procédé (200) et un appareil (100) pour une radio comportant des paramètres de fonctionnement réglables, permettant de régler au moins un desdits paramètres de fonctionnement réglables basés sur l'emplacement effectif de la radio. Les paramètres de fonctionnement pouvant être ainsi réglés, sans être exhaustifs, comprennent: la puissance de transmission (106, 107), le canal de fonctionnement, la bande de fonctionnement (103, 104), le type de modulation, l'index de modulation, le glissement de fréquence, l'ajustement du silencieux, l'espacement des canaux, le canal de commande (109, 110) (pour communications interurbaines), les caractéristiques de suppression de bruit, et la largeur de bande de réception. L'emplacement est déterminé par la radio (101).
