  • Delivery of an incoming data call from a public switched telephone network to a mobile station
    Publication number: 20030054826
    Abstract: The present invention relates to a method for delivering an incoming data call from a Public Switched Telephone Network (PSTN) to a Mobile Station (MS). A Mobile Switching Center (MSC) first receives an incoming call and initiates a call setup procedure with an Interworking Function (IWF). The IWF adapts the data call for a cellular network and completes the call setup procedure with the MSC. The MSC then initiates a connection with a Base Station Controller (BSC) currently serving the MS. After the connection is completed, the PSTN is informed and data transfer with the MS can is initiated.
