COMMUNICATIONS SYSTEM FOR ESTABLISHING COMMUNICATIONS BETWEEN MOBILE DEVICE AND TELEPHONE NETWORK OR BROADBAND NETWORK

摘要

A communications system includes an adapter, an internet access device and a mobile device. The adapter is linked to a telephone network or a broadband internet network and configured to transceive voice data via the telephone network or the broadband internet network, perform data conversion between the voice data and corresponding internet protocol packets, and transceive the internet protocol packets. The internet access device is linked to the adapter and configured to make the adapter access an internet network. The mobile device is linked to the internet access device via the internet network and configured to transceive the internet protocol packets via the internet network. Communications between the adapter and the mobile device may be therefore established.
