Abstract

In current trunked systems, a remote site must be taken down or have its trunking services reduced (i.e. change t?om wide trunking to site trunking) when the remote site's software is upgraded from a centralized location using Flash technology. The reduction in trunking capability is necessary during the transfer time period because of the magnitude of the data being transferred as well as the processing power required to control the transfer. Thus, during the transfer time period, an undesirable trunking state is encountered.

REMOTE SITE TRANSPARENT SOFlWARE UPGRADE

by Jeffrey Shroda, Michael Wirtjes and Kristin Cramer

BACKGROUND

In current trunked systems, a remote site must be taken down or have its trunking services reduced
(i.e. change t?om wide trunking to site trunking) when the remote site's software is upgraded from a centralized location using Flash technology. The reduction in trunking capability is necessary during the transfer time period because of the magnitude of the data being transferred as well as the processing power required to control the transfer. Thus, during the transfer time period, an undesirable trunking state is encountered.

SOLUTION

  The solution to this problem is to embed the new software data in the current control signaling that is transmitted from the central site to a base station at a remote site. The new data would also be

embedded in the messages that are sent from one base station to other base stations through the sites LAN.

  Once a base station at the remote site receives the data in its entirety from the centralized loca- tion, the data will be distributed and selectively acti- vated on each base station until all base stations at the site have been upgraded and are executing the new software. The selective activation process pref- erably comprises activating the new software at base stations not currently in use (i.e. idle channels), acti- vating the new software on base stations as they become deassigned from call or dat...
