Abstract
A telecommunications system provides a call transfer function while user-A is involved in two independent calls: one with user-B and one with user-C. The call transfer by user-A is initiated by sending a message to the long distance carrier switching office. In the switching office, both independent calls are identified as part of the transfer request. The switching office then requests the call transfer function by sending a message to the network control system for the validation of the transfer. After the network control system determines allowability of the transfer, the call between user-B and user-C is connected, while user-A and user-A's customer premise equipment is disconnected from user-B and user-C.
