Abstract

In a particular embodiment, the disclosure is directed to a mobile communication device including an antenna, mobile telephony circuitry, a service request module and a voice conversion module. The mobile telephony circuitry is configured to communicate with a mobile telephony network using a mobile communication protocol. The mobile telephony circuitry is coupled to the antenna. The service request module is configured to determine the proximity to a wireless network base station using a wireless data network protocol. The service request module is configured to establish a communication path via the wireless data network protocol. The voice conversion module is configured to convert voice communication to packet data to be communicated using the wireless data network protocol to the wireless network base station.

Claims
