  • Performing handoff of a mobile station between different types of wireless network controllers
    Patent number: 8577370
    Abstract: To perform handoff of a mobile station from a source wireless network controller of one wireless access technology to a target wireless network controller of a different wireless access technology, a first message for initiating a handoff is sent from the source wireless network controller to the target wireless network controller. The source wireless network controller receives, from the target wireless network controller, a second message responsive to the first message, where the second message contains information to enable identification of cell segments neighboring the target wireless network controller for which signal strength measurements are to be performed. In response to the second message, signal strength measurements made by the mobile station are received by the target wireless network controller.
