Patent ID: 8676120

Claim:
A wireless communication system, comprising: a wireless relay coupled to a phone network; and a mobile terminal physically coupled to the wireless relay to make a voice communication with the phone network via the wireless relay, wherein the mobile terminal and the wireless relay exchange control data and voice data corresponding to the voice communication over a short-range wireless link based on one of a transparent mode and a translation mode, a signaling connection is established on an asynchronous connection-oriented logical (ACL) transport channel between the mobile terminal and the wireless relay for exchanging the control data, and a voice connection is established on a synchronous connection oriented (SCO) channel between the mobile terminal and the wireless relay for exchanging the voice data, the mobile terminal is connected to the wireless relay through a connector interface including a charging interface and a data interface to provide a wired-connection link between the wireless relay and the mobile terminal, the connector interface further includes an insertion detection unit configured to generate an insertion event when the mobile terminal is inserted into the wireless relay and a removal event when the mobile terminal is removed from the wireless relay, wherein the wireless relay or the mobile terminal is further configured to: determine a current connection status; when the current connection status is the short-range wireless link, wait for the insertion event from the insertion detection unit; and when the current connection status is the wired-connection link, wait for the removal event from the insertion detection unit.
