ABSTRACT:
A wireless communication device without IP capability nonetheless communicates with an infrastructure that uses IP. To effect call set-up, an over-the-air (OTA) origination message from the wireless communication device is received by an infrastructure component, which in turn generates IP-based messages having headers that are extended to include information related to the OTA protocol. The IP-based messages with extended headers are then used internally to the infrastructure to effect call set-up.
