Abstract
Dividing the function of wireless handset control from the function of telecommunication call control in a software architecture of a wireless telecommunication system. The wireless handset control function follows the wireless handset as it registers and is handed off from switch node to switch node; the telecommunication call control function remains on the switch node on which the wireless handset first became active and remains on that switch node until the wireless handset becomes inactive. Upon the wireless handset becoming inactive, the wireless telecommunication call control function is transferred to the switch node on which the wireless handset is currently registered.
