Mobile device anchoring and connectivity across multiple mobile network technologies

摘要

A device may attach to a mobile service provider (MSP) network and establish a first communication path from the device to a packet data network (PDN) gateway in the MSP network. The device may also start a session over the first communication path and detect a wireless network which is available for establishing a second communication path that extends from the device to the PDN gateway over the wireless network. While the first communication path is intact, the device may: attach the device to the MSP network over the wireless network, wherein attaching the device over the wireless network includes establishing a second communication path from the device to the PDN gateway over the wireless network; evaluate conditions for the first communication path and the second communication path; and select one of the first and second communication paths as an active communication path based on the evaluated conditions.
