Abstract

In existing trunked systems there is a mecha- nism that transmits a site identification number over the air on a site's control channel. Any radio monitoring the control channel at this site will receive this site ID. As implied by the name, the site ID is just a number used to identify a particular site. Many customers prefer to reference the site number with a site alias. A site alias is a textual description ofthe site derived From the site ID. This allows for easier determination of a subscriber user's current site asso- ciation. An example of a site alias might be "CHCAGOI' In today's trunked systems the site alias is not transmitted over the control channel, only the site number. In order to facilitate the usage of site aliases, the user must have the site alias infor- mation preprogrammed in the subscriber unit. The subscriber unit then makes a translation from site number to site alias in order to display this informa- tion to the user.
