Abstract
A mobile switching center (MSC) not equipped with the necessary hardware/software devices or modules communicates with a Shared Interworking Function node to provide an Interworking function (IWF) service to a particular mobile station. Control data associated with the requested IWF service are transported from the serving MSC to the SIWF node using basic and supplementary Integrated Service Digital Network User Part (ISUP) signals. Such control data are encapsulated into optional parameters within the transmitted ISUP signals and transparently transported from the serving MSC to the SIWF telecommunications node.
