Abstract
Systems and methods for improved inter-technology handovers between wireless networks are disclosed, in which a source radio access network operates on a first technology and a target radio access network operates on a second technology, and both radio access networks are managed at a single packet serving gateway. A foreign agent receives a mobile subscriber identifier during a handover of a mobile device from the source radio access network to the target radio access network and sends the mobile subscriber identifier to the packet serving gateway, and the packet serving gateway locates at least one process instance running on the packet serving gateway that is routing existing packet flows to the mobile device based on the mobile subscriber identifier. The packet serving gateway then transfers control of the at least one process to a control process.
