1. A method for providing telecommunication features to wireless telecommunication terminals interconnected to a mobility switch node that is connected to a telecommunication switching system via a plurality of telecommunication links and the mobility switch node is executing a plurality of first type of applications and plurality of second type of applications, the method comprising the steps of:

  • receiving a control message by one of the plurality of first type of applications in the mobility switch node from a wireless telecommunication terminal requesting execution of a telecommunication feature;

    converting the control message by the one of the plurality of first type of applications to an internal protocol message to designate the execution of the telecommunication feature;

    transmitting the internal protocol message requesting execution of the telecommunication feature by the one of the plurality of first type of applications to one of a plurality of second type of applications;

    receiving the transmitted internal protocol message and converting the internal protocol message to a telecommunication link protocol message by one of the plurality of second type of applications to designate the execution of the telecommunication feature;

    transmitting the telecommunication link protocol message via one of the plurality of telecommunication links individually assigned to the telecommunication terminal by the one of the plurality of second type of applications to the telecommunication switching system that performs the requested telecommunication feature as if a telecommunication terminal was connected to the telecommunication switching system via the one of the plurality of telecommunication links.
