Abstract:
1. A telecommunications system comprising: a first functional entity comprising a mobile gateway and a second functional entity comprising a mobile switching control emulator (MSCe) in first packet switched (PS) network; and a third functional entity comprising a mobile gateway and a fourth functional entity comprising an MSCe in a second PS network; said first functional entity and said second functional entity including means for communicating signals using a first PS protocol; said third functional entity and said fourth functional entity including means for communicating signals using the first PS protocol; said first functional entity having means for communicating packet data to and from said third functional entity; said second functional entity having means for mapping a circuit switched (CS) network message to a first PS protocol signal message using a second PS protocol; said second functional entity further having means for transmitting the first PS protocol signal message to said fourth functional entity using a second PS protocol; said fourth functional entity further including means for communicating the CS network message using a CS protocol to and from a CS network to terminate the CS communication; and said second functional entity further including means for communicating a signal using a third PS protocol to and from an access network.
