Abstract

A method is provided in one example embodiment and includes receiving a request associated with a flow over a wireless link, where the request specifies resource requirements for the flow. The method also includes mapping an Internet protocol (IP) flow description to a plurality of tunnel IP addresses, and mapping a framed IP address to an access point (AP) tunnel endpoint address in order to establish a quality of service (QoS) for tunneled traffic.

Claims (43)

1. A method, comprising:

receiving a request associated with a flow over a wireless link, wherein the request specifies resource requirements for the flow;

mapping an Internet protocol (IP) flow description to a plurality of tunnel IP addresses; and

mapping a framed IP address to an access point (AP) tunnel endpoint address in order to establish a quality of service (QoS) for tunneled traffic.

2. The method of claim 1 , further comprising:

recovering asynchronous signaling of updated transport IP addresses as a result of at least one mobility event.

3. The method of claim 1 , further comprising:

reconfiguring a message received from an application function in order to provide a mapping to the tunnel IP addresses.

4. The method of claim 3 , wherein the message includes media component descriptions and uplink/downlink bandwidth data.

5. The method of claim 1 , wherein the wireless link is coupled to a Data over Cable Service Interface Specification (DOCSIS) link associated with a cable modem and a cable modem termination system (CMTS).

6. The method of claim 5 , wherein Packet Cable Multimedia (PCMM) interfaces are used to establish the QoS for a DOCSIS IP transport network.

7. The method of claim 1 , wherein remote authentication dial in user service (RADIUS) protocol interim messages are used for signaling the tunnel IP addresses.

8. The method of claim 1 , further comprising:

signaling an access network for previously allocated resources to be released; and

signaling the access network for newly allocated transport resources to be reserved for tunneled transport.

9. The method of claim 1 , wherein the request includes a quality of service parameter corresponding to the resource requirements.

10. The method of claim 1 , wherein the tunnel IP addresses are associated with a control and provisioning of wireless access points (CAPWAP) tunnel between a Wi-Fi access point (AP) and a wireless local area network controller (WLC).

11. The method of claim 1 , wherein the tunnel IP addresses are associated with a GPRS Tunneling Protocol (GTP) tunnel between a service gateway (SGW) and a packet data network (PDN) gateway (PGW).

12. The method of claim 1 , wherein the tunnel IP addresses are associated with a GPRS Tunneling Protocol (GTP) tunnel between an eNode B (eNodeB) and a service gateway (SGW).

13. The method of claim 1 , wherein a layer-1 point of attachment (PoA) with an access network is changed as a result of at least one mobility event.

14. The method of claim 13 , further comprising:

providing an asynchronous indication to a previous querying element that at least one of the tunnel IP addresses have changed as a result of the at least one mobility event.

15. A non-transitory media encoded with logic that includes code for execution and when executed by a processor operable to perform operations comprising:

receiving a request associated with a flow over a wireless link, wherein the request specifies resource requirements for the flow;

mapping an Internet protocol (IP) flow description to a plurality of tunnel IP addresses; and

mapping a framed IP address to an access point (AP) tunnel endpoint address in order to establish a quality of service (QoS) for tunneled traffic.

16. The non-transitory media of claim 15 , the operations further comprising:

reconfiguring a message received from an application function in order to provide a mapping to the tunnel IP addresses, wherein the message includes media component descriptions and uplink/downlink bandwidth data.

17. The non-transitory media of claim 15 , wherein the wireless link is coupled to a Data over Cable Service Interface Specification (DOCSIS) link associated with a cable modem and a cable modem termination system (CMTS).

18. An apparatus, comprising:

a memory element configured to store electronic code;

a processor operable to execute instructions associated with the electronic code; and

a mapping function configured to interface with the processor such that the apparatus is configured to:

receive a request associated with a flow over a wireless link, wherein the request specifies resource requirements for the flow;

map an Internet protocol (IP) flow description to a plurality of tunnel IP addresses; and

map a framed IP address to an access point (AP) tunnel endpoint address in order to establish a quality of service (QoS) for tunneled traffic.

19. The apparatus of claim 18 , the apparatus being further configured to:

reconfigure a message received from an application function in order to provide a mapping to the tunnel IP addresses, wherein the message includes media component descriptions and uplink/downlink bandwidth data.

20. The apparatus of claim 18 , wherein the wireless link is coupled to a Data over Cable Service Interface Specification (DOCSIS) link associated with a cable modem and a cable modem termination system (CMTS).

21. The apparatus of claim 18 , wherein the wireless link is associated with a selected one of a group of transport networks, the group consisting of:

a) a control and provisioning of wireless access points (CAPWAP) network;

b) a DOCSIS network; and

c) a Telecoms & Internet converged Services & Protocols for Advanced Networks (TISPAN) network.
