摘要： Establishing a circuit-switched fallback (CSFB) call. A request to establish a CSFB call may be received. A first wireless link with a first cell may be released. The first cell may provide packet-switched services but not circuit-switched services. A second wireless link may be established with a second cell. The second cell may provide packet-switched services and circuit-switched services. The CSFB call may be established via the connection to the second cell. Packet-switched registration with the second cell may be performed after the CSFB call is established.
