  • the device For devices that do not implement double images, during the process of firmware upgrade over-the-air, the device is run in non operational mode. This is to ensure that the firmware upgrade can be performed successfully. This would mean that all active user sessions would be terminated. This might cause a huge impact to the users if they are performing critical operation such as online banking, reservations, etc. Additionally, wireless access point devices do not have direct user interaction; hence firmware upgrade cannot be controlled by the users.

  • the problem of interrupting user sessions has now been addressed by the method of WAP device requiring firmware upgrade being able to decide when to perform the upgrade. The device should go ahead with firmware upgrade if there are no active user sessions else delay the upgrade and initiate it at a later point in time when there are no active users.
  • This invention is adapted for enabling initiation of firmware upgrades to be done on wireless access point devices in a wireless network by an operator server without disrupting active user sessions as well as without user intervention.
  • the disclosed invention is suitable, but not restricted to, for use in wireless networks.

Abstract

L'invention concerne un procédé d'initiation de mises à niveau de micrologiciel sur un dispositif sans fil connecté à un réseau sans fil, le procédé comprenant les étapes consistant à recevoir une requête de mise à niveau de micrologiciel à partir du réseau sans fil, à mettre à niveau un micrologiciel s'il n'y a pas de sessions d'utilisateur actif, à configurer le drapeau de mise à niveau dans une mémoire non volatile s'il y a des sessions d'utilisateur actif, à mettre à niveau un micrologiciel lorsque le dispositif sans fil n'a pas d'utilisateurs actifs ou lorsque le dispositif sans fil est mis sous tension et qu'un drapeau de mise à niveau est configuré.
