ABSTRACT:
The invention provides a layered channel software element which supervises the operation of channel element modem resources in a CDMA cellular telephone system that includes forward channels for conveying message and signalling data from a CDMA system base station to mobile units and reverse channels for conveying message and signalling data from mobile units to base stations. Each channel is implemented in a channel element including a general purpose processor and a modem application-specific integrated circuit ASIC. The layered channel software element executes on the general processor. The layered channel software element provides a structure and function for transferring message and signalling data between the telecommunication system and the modem ASIC and also for establishing channel operations by providing channel configuration information to the modem ASIC.
