sending from the MS an INVITE command in accordance with Session Initiation Protocol (SIP), the INVITE command including an Internet Protocol (IP) address, and at least one of a call identifier and a caller identifier.

4. A mobile station (MS) capable of communicating with a communication system through both a wireless connection and a wired connection, the MS arranged for switching an ongoing communication of user information between the wireless connection and the wired connection, the MS comprising:

a wireless interface for making the wireless connection;

a wired interface for making the wired connection; and

a processor coupled to the wireless interface and coupled to the wired interface for controlling the MS, wherein the processor is programmed to cooperate with the wired and wireless interfaces to:

establish, between the MS and a communication device coupled to the communication system, a first one of the wireless connection and the wired connection, the wired connection existing through a wired local area network (LAN);

communicate a first portion of the user information between the MS and the communication device through said first one of the wireless connection and the wired connection;

subsequently establish, between the MS and the communication device a second one of the wireless connection and the wired connection, said second one different from said first one; and

communicate a second portion of the user information through said second one of the wireless connection and the wired connection.

5. The MS of claim 4 , wherein the user information comprises a real-time multimedia communication.

6. The MS of claim 4 , wherein in establishing the second one of the wireless connection and the wired connection, the processor is further programmed to:

send from the MS an INVITE command in accordance with Session Initiation Protocol (SIP), the INVITE command including an Internet Protocol (IP) address, and at least one of a call identifier and a caller identifier.

7. The MS of claim 4 , wherein the wired interface comprises a short-range wireless device for communicating between the MS and the LAN.

8. A module in a mobile station (MS) capable of communicating with a communication system through both a wireless connection and a wired connection, the module arranged for switching an ongoing communication of user information between the wireless connection and the wired connection, the module comprising:

a wireless interface for making the wireless connection;

a wired interface for making the wired connection; and

a processor coupled to the wireless interface and coupled to the wired interface for controlling the MS, wherein the processor is programmed to cooperate with the wired and wireless interfaces to:

establish, between the MS and a communication device coupled to the communication system, a first one of the wireless connection and the wired connection, the wired connection existing through a wired local area network (LAN);

communicate a first portion of the user information between the MS and the communication device through said first one of the wireless connection and the wired connection;

subsequently establish, between the MS and the communication device a second one of the wireless connection and the wired connection, said second one different from said first one; and

communicate a second portion of the user information through said second one of the wireless connection and the wired connection.

9. The module of claim 8 , wherein the user information comprises a real-time multimedia communication.

10. The module of claim 8 , wherein in establishing the second one of the wireless connection and the wired connection, the processor is further programmed to:

send from the MS an INVITE command in accordance with Session Initiation Protocol (SIP), the INVITE command including an Internet Protocol (IP) address, and at least one of a call identifier and a caller identifier.

11. The module of claim 8 , wherein the wired interface comprises a short-range wireless device for communicating between the MS and the LAN.

12. A method using a mobile station capable of communicating through both a wireless connection and a wired connection, the method for switching an ongoing communication between the wireless connection and the wired connection, the method comprising the steps of:

establishing, between the mobile station and a communication device coupled to the communication system, a first one of the wireless connection and the wired connection, the wired connection existing through a wired local area network;

communicating a first portion of the communication between mobile station and the communication device through said first one of the wireless connection and the wired connection to establish the ongoing communication;

subsequently establishing, between the mobile station and the communication device a second one of the wireless connection and the wired connection, said second one different from said first one;

switching the ongoing communication between the first one of the wireless connection and the wired connection and the second one of the wireless connection and the wired connection; and

communicating a second portion of the user information through said second one of the wireless connection and the wired connection.

13. The method according to claim 12 , wherein the communication comprises a real-time multimedia communication.

14. The method according to claim 12 , wherein the step of establishing the second one of the wireless connection and the wired connection comprises the step of sending from the mobile station an INVITE command in accordance with Session Initiation Protocol, the INVITE command including an Internet Protocol address, and at least one of a call identifier and a caller identifier.

15. The method according to claim 12 , wherein the step of establishing a first one of the wireless connection and the wired connection further comprises establishing a wireless connection.

16. The method according to claim 15 , wherein the step of subsequently establishing a second one of the wireless connection and the wired connection further comprises establishing a local area network connection by physically connecting a wired interface of the mobile station to a local area network.
