Abstract
A mobility management system and a traditional telecommunication switching system provide telecommunication terminal features by the mobility management system executing a software architecture that utilizes a unique terminal management application for each type of wireless terminal and a unique terminal emulator application for each type of telecommunication link that interconnects the mobility management system to the telecommunication switching system. There is an individually assigned telecommunication link for each wireless terminal. The terminal management applications and the terminal emulator applications communicate utilizing an internal message protocol. In response to a wireless terminal requesting actuation of a feature, a terminal management application converts that request into the required internal protocol messages and transmits the internal protocol messages to the terminal emulator application that controls the telecommunication link assigned to the wireless terminal. In response to the internal protocol messages, the terminal emulator application emulates the type of telecommunication terminal that normally would be connected to the assigned telecommunication li…
