Abstract
A wireless relay apparatus is provided. The wireless relay apparatus includes a telephone module configured to couple with a public switched telephone network (PSTN) to receive a telephone call, and a wireless module coupled to the telephone module to process the telephone call and configured to wirelessly connect to a mobile terminal such that the telephone call is forwarded to the mobile terminal over a short-range wireless link. Further, the wireless module is configured to operate in one of a transparent mode and a translation mode so as to exchange voice data with the mobile terminal.
Claims22
A wireless relay apparatus, comprising:
- a telephone module configured to couple with a public switched telephone network (PSTN) to receive a telephone call from an external party;
- and
- a wireless module coupled to the telephone module to process the telephone call and configured to wirelessly connect to a mobile terminal such that the telephone call is forwarded to the mobile terminal over a short-range wireless link along with signaling information for the mobile terminal to establish both a signaling connection and a voice connection with the external party,
- wherein the wireless module is configured to be operable in a transparent mode, under which the wireless module uses standard modem commands supported by the telephone module to exchange control data corresponding to the phone call with the mobile terminal, and a translation mode, under which the wireless module uses abstract telephony protocol (ATP) commands to exchange control data corresponding to the phone call with the mobile terminal and translates the ATP commands into the standard modem commands supported by the telephone module, so as to exchange voice data with the mobile terminal.

A mobile wireless terminal, comprising:
- a wireless unit configured to connect to a wireless relay over a short-range wireless link for receiving a telephone call forwarded by the wireless relay coupled between the mobile wireless terminal and a public switched telephone network (PSTN), the telephone call being originated from the PSTN;
- an audio codec to process voice signals corresponding to the telephone call;
- and
- a processor unit coupled to the wireless unit to process the telephone call such that the telephone call is answered by the mobile wireless terminal,
- wherein the processor unit is configured to support a transparent mode, under which the processor unit uses standard modem commands supported by a telephone module in the wireless relay to exchange control data corresponding to the phone call with the mobile wireless terminal, and a translation mode, under which the processor unit uses abstract telephony protocol (ATP) commands to exchange control data corresponding to the phone call with the wireless relay and translates the ATP commands into the standard modem commands supported by the telephone module, so as to exchange voice data with the wireless relay.

A method for a wireless communication system including a mobile terminal and a wireless relay to couple between the mobile terminal and a public switched telephone network (PSTN), comprising:
- discovering, by the mobile terminal, the wireless relay;
- connecting, by the mobile terminal, to the wireless relay after the wireless relay is discovered;
- registering, by the wireless relay, the mobile terminal after receiving a register request from the mobile terminal based on a database containing registration information of a plurality of mobile terminals;
- and
- initiating, by the mobile terminal, a telephone call to the PSTN via the wireless relay,
- wherein the mobile terminal and the wireless relay exchange voice data corresponding to the telephone call over a short-range wireless link operable in a transparent mode, under which the wireless relay uses standard modem commands to exchange control data corresponding to the phone call with the mobile terminal, and a translation mode, under which the wireless relay uses abstract telephony protocol (ATP) commands to exchange control data corresponding to the phone call with the mobile terminal and the wireless relay translates the ATP commands into standard modem commands.
