Abstract

A telecommunications device and network that provides TCP/IP communications over the entire data path, thereby simplifying the software call stack needed for a wireless device or to communicate with the network. The device eliminates the upper layers (non-access-stratum) of the handset call stack. It reduces the role of the radio layer to just providing link layer services. Furthermore, the handset call stack communicates with session control and billing & authorization servers over a public network such as the internet. Further, the wireless devices, as well as base stations and other components, communicate with session servers and billing & authorization servers over a public network, such as the Internet, eliminating any need for dedicated private-network connection between these components.

Claims

1. A mobile terminal comprising:

a first software layer for wireless communications link control; and

a second software layer for session control and communications,

wherein the second software layer communicates with a session control system over a public network.

2. The mobile terminal of claim 1, wherein the first software layer includes a link control component and a medium access control component.

3. The mobile terminal of claim 1, wherein the second software layer comprises software components selected from the group consisting of an Internet Control Message Protocol component, an Internet Group Message Protocol component, a Internet Protocol component, a Session Initiation Protocol component, a Realtime Transport Protocol component, a Transmission Control Protocol component, a User Datagram Protocol component, and a Medium Access Control component.

4. The mobile terminal of claim 1, wherein the session control system is a session initiation protocol proxy.

5. The mobile terminal of claim 1, wherein the session control system is a session initiation protocol registrar.

6. The mobile terminal of claim 1, wherein the public network is the internet.

7. The mobile terminal of claim 1, wherein the first software layer communicates with an authorization system over the public network.

8. The mobile terminal of claim 1, wherein the first software layer controls local radio layer mobility and the second software layer controls internet-protocol mobility, and wherein the second software layer is only used during an active data or voice transfer session.

9. The mobile terminal of claim 1, wherein no third software layer is present.

10. A wireless communications network comprising;

a plurality of base stations configured to communicate with at least one mobile terminal;

a gateway configured to deliver communications from the mobile terminal to the public switched telephone network;

a session control system configured to control communications with the mobile terminal over a public network; and

a call accounting system configured to control communications with the mobile terminal over a public network.

11. The wireless communications network of claim 10, wherein the public network is the Internet.

12. The wireless communications network of claim 10, wherein all communications are internet protocol communications.

13. The wireless communications network of claim 10, wherein the session control system is a session initiation protocol proxy.

14. The wireless communications network of claim 10, wherein the session control system is a session initiation protocol registrar.

15. A method for enabling wireless communications, comprising;

receiving, in a base station, an internet-protocol communications request from a wireless device;

transmitting an authorization request corresponding to the internet-protocol communications request, over a public network, to a wireless carrier authorization server;

receiving a service authorization corresponding to the communications request from the wireless carrier authorization server; and

enabling voice-over-internet-protocol communications between the wireless device and the public network.

16. The method of claim 15, further comprising transmitting the voice-over-internet-protocol communications to a public service telephone network gateway.

17. The method of claim 15, further comprising transmitting a message corresponding to the communications request to a session initiation protocol proxy.

18. The method of claim 15, further comprising transmitting a message corresponding to the communications request to a session initiation protocol registrar.

19. The method of claim 15, wherein the communications request includes a wireless device identifier.

20. The method of claim 15, wherein the public network is the internet.
