Abstract

Today on a Motorola Trunked Communications system, there exists a limitation on the amount of OSW traffic a mobile can tolerate while waiting for an update transaction from the CSC. This limita- tion is currently 172 OSW's (4 set). In today's global economic situation with resources becoming scarce, Tiunked Communication systems are getting loaded beyond capacity. This creates a phenomenon ofcon- trol channel flooding; where-during peak hours of usage-there becomes a very high number of mobile updates transmitted over the control channel, thus increasing control channel tragic. This in turn extends the amount of time a mobile has to wait before its update is received. If the mobile doesn't receive an update Within 172 OSW's (4 set), it will time-out and revert to a dormant state. Obviously a way to overcome this issue is to increase the number of OSW's before a radio will time-out. But this only creates another limitation.
