Abstract
A technique for interconnecting circuit-switched (CS) and packet-switched (PS) domains enables network components () having a PS network access to make use of CS telephony services. A method embodiment of this technique comprises the steps of receiving PS control information according to a PS control protocol such as SIP, determining, in response to receipt of the PS control information, CS control information according to a CS control protocol such as DTAP, and sending the determined CS control information to a second network component () that is located on an application (or service) layer for provision of CS services, based on the determined CS control information, to the first network component ().
