Abstract

For voice, when assigning a RF channel resource for an FDMA call at an RF Site with mixed FDMA only and Dynamic FDMA/TDMA RF channels, the call controller will assign the call to an anassigned FDMA only channel over an unassigned Dynamic FDMA/TDMA capable channel, all other things being equal. -the benefit is to keep the Dynamic FDMA/TDMA channel open -- so that either FDMA/TDMA call type could be serviced with future assignments. Likewise for voice, when assigning a RF channel resource for a TDMA call at an RF Site with mixed TDMA only and Dynamic FDMA/TDMA RF channels, the call controller will assign the call to an unassigned TDMA only channel over an unassigned Dynamic FDMA/TDMA capable channel, all other things being equal. For Voice, when assigning a TDMA call to either 1) an one or two TDMA only channel slots or a Dynamic FDMA/TDMA channel with one open slot, the call controller will assign the call to the open TDMA only channel slot. This is to preserve the Dynamic FDMA/TDMA channel -- so that either FDMA/TDMA call type could be serviced with future assignments. For Data calls: The system will assign IV&D data calls using the following preferences: (1st) FDMA Only channels, (2nd) Dynamic channels, (3rd) TDMA Only channels. The logic here is that we need to allow IV&D data calls on TDMA only channels & favor the call going to an FDMA type channel first - as a Data call is an FDMA type call.
