Abstract

A method for providing telephone communications in a system including a wide area data network and a wireless cellular mobile telephone network. A local cellular mobile telephone operator serves the wireless cellular mobile telephone network by providing a radio communications interface within a local region. The local cellular mobile telephone operator issues a subscriber identity module (SIM) to a user of the wireless cellular mobile telephone network. A communications terminal interfaces to the wide area data network using a radio interface to a base transceiver station (BTS) of the wireless cellular mobile telephone network within the local region. The communications terminal includes a communications module for handling a telephone communication through the wide area data network and the wireless cellular mobile telephone network. The communications terminal includes a subscriber identity module (SIM) emulator. A client computer is attached to the wide area data network at a remote site outside the local region. The client computer includes a subscriber identity module (SIM) reader. Telephone communications are provided by (a) inserting the SIM card into the SIM reader (b) transferring SIM identification data of the SIM card to the terminal over the wide area data network and (c) emulating the SIM card based on the SIM identification data. The emulation is performed by the emulator at the communications terminal. The SIM data is provided to the wireless cellular mobile telephone network operator within the local region over the radio communications interface.

Claims

1. In a system including a wide area data network and a wireless cellular mobile telephone network, wherein a local cellular mobile telephone operator serves the wireless cellular mobile telephone network within a local region, wherein the local cellular mobile telephone operator issues a subscriber identity module (SIM) to a user of the wireless cellular mobile telephone network, the system comprising:

(a) a communications terminal which interfaces to the wide area data network using a radio interface to a base transceiver station of the wireless cellular mobile telephone network within the local region, wherein said terminal includes a communications module for handling a telephone communication through the wide area data network and the wireless cellular mobile telephone network, and wherein said communications terminal includes a subscriber identity module (SIM) emulator, wherein said communications terminal operationally connects to the wireless cellular mobile telephone network solely through said base transceiver station via said radio interface without direct connection to the wireless cellular mobile telephone network; and

(b) a client computer operatively attached to the wide area data network at a remote site, wherein said client computer includes a subscriber identity module (SIM) reader;

wherein the remote site is outside the local region;

wherein a user of said client computer inserts said SIM card into said SIM reader, wherein SIM authentication data of said SIM card is transferred to said communications terminal over the wide area data network, and wherein said SIM emulator provides said SIM authentication data to the wireless cellular mobile telephone network within the local region.

2. The system according to claim 1, further comprising:

(c) a server operatively attached to the wide area data network, said server including a SIM server and a session initiation protocol (SIP) server which mediate data transfer between said client computer and said communications module for authentication of said SIM authentication data and registration of said SIM card.

3. The system according to claim 1, further comprising:

(c) a server operatively attached to the wide area data network, said server including a SIM server and a session initiation protocol (SIP) server which mediate initiation of said telephone communication through the wide area data network, said telephone communications between said client computer and said communications module of said communications terminal.

4. The system according to claim 3, wherein after said initiation of said telephone communication, bi-directional data streams of said telephone communication are transferred between said communications terminal and said client computer but not through said server.

5. The system according to claim 1, further comprising:

(d) an authentication mechanism whereby said SIM authentication data is passed from said client computer to said communications terminal, wherein said SIM authentication data is required for authenticating said SIM module by the local cellular mobile telephone operator.

6. In a system including a wide area data network and a wireless cellular mobile telephone network, wherein a local cellular mobile telephone operator serves the wireless cellular mobile telephone network by providing a radio communications interface within a local region, wherein the local cellular mobile telephone operator issues a subscriber identity module (SIM) to a user of the wireless cellular mobile telephone network, the system including a communications terminal which interfaces to the wide area data network using a radio interface to a base transceiver station (BTS) of the wireless cellular mobile telephone network within the local region, wherein said communications terminal includes a communications module for handling a telephone communication through the wide area data network and the wireless cellular mobile telephone network, and wherein said communications terminal includes a subscriber identity module (SIM) emulator, wherein said communications terminal operationally connects to the wireless cellular mobile telephone network solely through said base transceiver station via said radio interface without direct connection to the wireless cellular mobile telephone network;

the system further including a client computer operatively attached to the wide area data network at a remote site outside the local region, wherein the client computer includes a subscriber identity module (SIM) reader, a method for providing telephone communications, the method comprising the steps of;

(a) providing the SIM reader with the SIM card inserted therein;

(b) transferring SIM authentication data of said SIM card to said terminal over the wide area data network;

(c) emulating said SIM card based on said SIM authentication data, said emulating performed by said emulator at the communications terminal; and

(d) providing said SIM authentication data to the wireless cellular mobile telephone network operator within the local region solely over the radio communications interface.

7. The method according claim 6, further comprising the step of:

(e) transferring said SIM authentication data between said client computer and said terminal, wherein said SIM authentication data is required for authenticating said SIM module by the local cellular mobile telephone operator.

8. The method according claim 6, further comprising the steps of:

(e) providing a server operatively attached to the wide area data network, said server including a SIM server and a session initiation protocol (SIP) server; and

(f) mediating said telephone communication between said client computer and said communications module of said communications terminal through the wide area data network, said mediating by said server.

9. The method according to claim 8, wherein said mediating includes initiation of said telephone communication, and after said initiation, bi-directional data streams of said telephone communication are transferred between said communications terminal and said client computer but not through said server.
