Abstract

An access point comprising a first interface for communicating with a plurality of subscriber terminals wirelessly, wherein the access point supports an internet protocol push-to-talk service and supports a protocol for a quality of service enabled wireless local area network and a second interface for communicating with a broadband access network terminal is described.

Claims

1. A method comprising:

communicating, by an access point, with a plurality of subscriber terminals wirelessly, wherein the access point comprises a hardware integrated circuit, wherein the access point comprises an internet protocol multicast enabled access point, wherein the access point provides multicasting and routing functions related to an internet protocol push-to-talk service and supports a protocol for a quality of service enabled wireless local area network, and wherein the access point further provides a voice over internet protocol telephony service, wherein the communicating with the plurality of subscriber terminals wirelessly comprises exchanging voice, data and multimedia information; and

communicating, by the access point, with a broadband access network terminal, wherein the access point provides information exchange between additional access points, the broadband access network terminal and a wireless local area network mobile radio service controller via an internet protocol network of a service provider.

2. The method of claim 1, wherein the access point provides signaling and control information exchanged between the additional access points, the broadband access network terminal and the wireless local area network mobile radio service controller via the quality of service enabled wireless local area network and the service provider internet protocol network.

3. The method of claim 1, wherein the access point provides mobility for terminal, personal and services management.

4. The method of claim 1, wherein the access point provides authentication, authorization and accounting services and associated network control and signaling exchange.

5. The method of claim 1, wherein the access point provides a call feature application via a network protocol including a session initiation protocol.

6. The method of claim 1, wherein the access point provides radio frequency and radio management processes related to the internet protocol push-to-talk service.

7. The method of claim 1, wherein the access point provides operation, administration, maintenance and provisioning processes related to the internet protocol push-to-talk service.

8. The method of claim 1, wherein the access point provides security management processes including subscriber authentication, and data encryption for privacy for the internet protocol push-to-talk service.

9. The method of claim 1, wherein the access point provides a wired local area network interface for information exchange associated with the internet protocol push-to-talk service.

10. The method of claim 1, wherein the access point provides mobility, and personal and service management.

11. The method of claim 1, wherein the access point provides sending and receiving multicast applications associated with a user datagram protocol, an internet protocol, an internet control message protocol, and an internet group management protocol.

12. The method of claim 1, wherein the access point provides network interface cards and drivers that filter internet protocol push-to-talk link layer and network internet protocol layer multicast addresses.

13. The method of claim 1, wherein the access point provides a call feature application via a network protocol including a media gateway control protocol.
