Patent ID: 7865199

Claim:
An Intelligent Network Control Node connectable to a Mobile Network Switching Node via a control interface and connectable to at least one Intelligent Network application module via an application interface, wherein said Intelligent Network Control Node comprises a data interface towards said Mobile Network Switching Node for exchanging Short Message Service messages, and a Transport Layer Controller adapted for sending and receiving the Short Message Service messages via the data interface, said Transport layer Controller further comprising a correlation means for correlating said exchange of said Short Message Service messages through said data interface with destination control data exchanged through said control interface; and a Correlation Identifier Table holding Correlation Identifiers used by said Transport Layer Controller for correlating sending and receiving the Short Message Service messages via the data interface with the control of Short Message Service message destinations via the control interfaces, and wherein the Correlation Identifier Table further comprises a pointer for indicating the next free Correlation Identifier to use, a list of Correlation Identifiers, each Correlation Identifier having a Correlation Identifier Number, a â€œFREE/BUSYâ€ flag for indicating that said Correlation Identifier is currently in use or is free, a Task/process Identifier for identifying an active task or process in the Intelligent Network application module, and a Mobile Party Identifier for identifying a Mobile Terminal.
