Abstract

When a SmartZone remote site goes into Site Trunking or Site Failsoft, all the radios at that site will want to affiliate at one of the adjacent sites that are in wide area trunking. Only radios that can not capture any other remote site or has this remote site set as a "Preferred Site:' will remain at this remote site. This will cause a great deal of traffic to be gen- erated to the Zone Controller (ZC), which will slow call request down.

  When a SmartZone remote site goes into Site Trunking or Site Failsoft, all the radios at that site will want to affiliate at one of the adjacent sites that are in wide area trunking. Only radios that can not capture any other remote site or has this remote site set as a "Preferred Site:' will remain at this remote site. This will cause a great deal of traffic to be gen- erated to the Zone Controller (ZC), which will slow call request down.

  Also when a site goes from site trunking or site failsofi back to wide area, these same radios that lefi the site that had a failure, will want to return to that site when the site goes back into wide area trunking because of the better coverage that this site may provide.

  To control the amount of traffic that will occur at the adjacent sites of the site that had a failure condition, the ZC will send an Affiliation Hold Off OSW out at all adjacent sites of the site that had the failure. This will keep all radios that came from the site that had the failure from affiliating. This Chili- ation Hold Off OSW would include the site number of the site that had the failure. This will allow radios that would do there normal affiliation due to power up or roaming from others sites to continue. The ZC will then go through the affiliation database and find all radios that were at the failure site by send-
