Abstract

The present invention allows calls that are controlled by a multimedia subsystem (MS) to employ bearer paths that are supported in whole or in part by a circuit-switched subsystem (CS). As such, calls controlled by the MS can have a portion of the bearer path provided through the CS when needed or desired. To facilitate such control, a session control signaling path is established between a user element currently supported by the CS and a remote user agent (RUA), which represents the user element in the MS. While a portion of the bearer path for the call is supported by the CS, the session control signaling path extends the reach of the MS to the user element.
