  • Communications network and method for screening incoming circuit switched calls
    Patent number: 6473422
    Abstract: A communications network and method for screening incoming circuit switched calls directed to a mobile terminal operating in packet switched mode. The communications network includes a circuit switched network and a packet switched network. A called party uses the mobile terminal to transmit to the packet switched network a screening list containing at least one listed phone number. The packet switched network uses the screening list to inform the called party whenever an incoming circuit switched call of a calling party has a phone number matching anyone of the listed phone numbers.

  • Processing packet-switched voice calls directed to a mobile unit operating in circuit-switched mode
    Patent number: 6307845
    Abstract: A packet-switched voice call directed to a mobile subscriber unit in a cellular communication network is processed by determining whether the mobile subscriber unit is in a circuit-switched mode of operation and, if so, either forwarding the information in the packet-switched voice call to a destination other than the mobile subscriber unit or notifying the mobile subscriber unit that the packet-switched voice call is waiting.
