  • the FCC wants the service providers, such as CMSPs, to overcome this overshooting scenario. In other words, the FCC does not want the mobile devices outside the affected area to receive the alert message.
  • FCC has recently published a new R&O that requires the CMSPs to deliver the coordinates of the affected area to mobile devices and then make modifications to the mobile devices to display the alert text only when the devices found themselves within the coordinates of the affected area.
  • FCC in the R&O stated that number of display characters sent to the devices should not be affected due to the fact that network utilizes the same channel to broadcast the coordinates of the affected area.

  • the DCM field for the new special WEA message will use the value to indicate the warning message contents are in binary form. That way, the devices can take the warning contents in the octet form.

  • the devices can display the text only if it had determined that its own location was within the coordinates of the affected area. For the special case where the device is unable to determine its own location, the device can follow the current logic and go ahead and display the text even if that results in an overshooting.

  • the enhanced device When the enhanced device receives the special WEA message, it will set the EDI field to ON when the device location is within the location determined by the affected area coordinates.

  • an eNB can send a new special WEA message with the coordinates of the affected alert area and a pointer to the WEA messages that carry the display text.
  • the mobile device can determine whether the device was within the coordinates of the affected alert area. If not, the device can reset the EDI field, namely to OFF, for the referenced WEA messages that carry the display text. Otherwise, if the device is within the coordinates, the device can set the EDI field, namely to ON, for the referenced WEA messages that carry the display text.
  • the real-time delay between the new special WEA message and the WEA message that carries the display text can be on the order of Si-Periodicity values. If the new special WEA message has one segment, if the next SIB 12 segment carries the referenced WEA message with the display text, then the real-time delay can be one Si-Periodicity. The lowest settable value 80 is ms and highest settable value is 5.12 seconds. In the event the device receives the WEA message that carries the display text first, then it will not display the text since the EDI field will not be set to ON. The device can handle the new special WEA message and the WEA message with the display text when the network repeats the same - in order of Si-Periodicity during the Paging period.
  • the device can set the EDI field to ON when it receives the new special WEA message that carries the coordinates of the affected alert area. That way, the devices that do not know location can continue to exhibit the behavior of the devices that do not have the enhancements, namely that they go ahead and display the text from the WEA message referenced in the special WEA message that carries the coordinates of the affected area.
  • certain embodiments can display the text if inside the coordinates, discard the message if outside the coordinates, and display the text, if the location is not known.
  • the alert text within the WEA message can continue to have 360 display characters since the alert coordinates are sent in separate special new WEA message.
  • the use of a new message identifier value can allow the approach to be backward compatible.
  • the network can broadcast each WEA message that carries the display text only once.
  • the old devices would display the alert text unconditionally and the new enhanced devices would display the alert text only if the device’s current location is within the coordinates of the affected area.
  • the new special WEA message that carries the coordinates of the affected alert area can be referred to as a geo-coordinate WEA message.
  • the WEA message that carries the display text can be referred to as a display text WEA message.
  • geo-coordinate can be used to refer the coordinates of the affected alert area.

Abstract

La présente invention concerne divers systèmes de communication pouvant bénéficier d'un ciblage géographique. Par exemple, certains systèmes de communication sans fil peuvent bénéficier d'une prise en charge de ciblage géographique pour éviter ou pour réduire au minimum le dépassement de notifications géo-ciblées. Un procédé peut consister, au niveau d'un nœud d'accès, à envoyer un premier message comprenant une alerte d'urgence sans fil assortie des coordonnées d'une zone d'alerte et d'une référence à au moins une alerte d'urgence sans fil ultérieure. Le procédé peut également consister, au niveau du nœud d'accès, à envoyer un second message comprenant la ou les alertes d'urgence sans fil ultérieures assorties d'un texte d'affichage.
