Optimizing supplementary service operations for lte-enabled devices

A computer-readable memory having stored thereon a sequence of instructions which, when executed by one or more processors, causes the one or more processors to optimize transactions involving CISS data on an LTE device by:

• receiving an indication that the CISS data should be transmitted between the device and a core network;
• 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:
• 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;
• or
• in response to a determination that the device is standing by in the circuit-switched 3G/2G network:
• sending the CISS data between the core network and the device in the circuit-switched 3G/2G network.

A mobile device comprising:

• one or more processors;
• and
• a memory communicatively coupled with and readable by the one or more processors and having stored therein a sequence of instructions which, when executed by the one or more processors, cause the one or more processors to optimize transactions involving CISS data on an LTE device by:
• receiving an indication that the CISS data should be transmitted between the device and a core network;
• 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:
• 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;
• or
• in response to a determination that the device is standing by in the circuit-switched 3G/2G network:
• sending the CISS data between the core network and the device in the circuit-switched 3G/2G network.
