Abstract
A method of optimizing transactions involving Call Independent Supplementary Service (CISS) data on a Long Term Evolution (LTE) device may include receiving an indication that the CISS data should be transmitted between the device and a core network. The method may also include determining whether the device is standing by in a packet-switched LTE network or standing by in a 3G/2G network. In response to a determination that the device is standing by in the packet-switched LTE network, the method may additionally include packaging the CISS data in a control layer message and sending the control layer message between the core network and the device in the packet-switched LTE network. In response to a determination that the device is standing by in the circuit-switched 3G/2G network, the method may further include sending the CISS data between the core network and the device in the circuit-switched 3G/2G network.
