Abstract
A method for delivering a mobile terminated call to a mobile device communicating with a mobile switching center (MSC) in one example comprises steps of attempting to deliver the mobile terminated call to a mobile device, receiving a message that the mobile device is no longer in the location area served by the visiting MSC and forwarding the mobile terminated call to a different visiting MSC. The mobile terminated call is forwarded directly from one VMSC to another VMSC without requiring two potentially international calls to be placed serially from the GMSC to a VMSC. This method of Mobile Termination Roaming Forwarding can reduce substantial delay in call setup while saving network resources during establishment of the first call.
