Abstract

Over-The-Air programming is a feature sup- ported by pagers to allow a service provider to pro- gram the codeplug of the pager by sending an OTA page. The OTA page consists of one or more of the following functions: a) disable the pager temporar- ily; b) enable the temporary disabled pager and c) change the feature set on the pager. With regards to these actions, the key point is that whenever the user is affected, he/she must be alerted. As such, after a valid OTA page is received and the appropri- ate commands executed, the pager will give a powerup alert to inform the user.

  Over-The-Air programming is a feature sup- ported by pagers to allow a service provider to pro- gram the codeplug of the pager by sending an OTA page. The OTA page consists of one or more of the following functions: a) disable the pager temporar- ily; b) enable the temporary disabled pager and c) change the feature set on the pager. With regards to these actions, the key point is that whenever the user is affected, he/she must be alerted. As such, after a valid OTA page is received and the appropri- ate commands executed, the pager will give a powerup alert to inform the user.

  Nevertheless, it can happen that duplicate OTA pages are sent. Most service providers usually send an OTA page more than once to ensure that the pager receives it because a pager might not receive a page if it is off or out of range. Since the same OTA page is received more than once, the pager will program the codeplug and powerup more than once. This can be very annoying to the user. For example, the user might not understand why the pager has powered-up more than once. Also while

an OTA page is being processed, no page can be received and the user may complain about missing normal pages (each byte of programming takes about 10 milliseconds). ~

  In view ofthese situations, it would be desirable to provide a duplicate lockout for OTA program- ming. The operation of'the duplicate OTA l...
