Bandwidth management for a converged gateway in a hybrid network
Systems and methods for integrating bandwidth management (BWM) equipment into a network in order to manage the use of bandwidth over multiple radio access technologies (RATs) relating to communications between a wireless transmit receive unit and a mobile core network (MCN). When integrating itself into the network, a BWM server may be placed between a MCN and an femto access point. In order for WTRUs to communicate with the MCN through the femto access point and a BWM server, a BWM server may need deep packet inspection capabilities.
1. A method of managing bandwidth over multiple radio access technology (RAT) links, the method comprising:
establishing a first internet protocol based tunnel between a bandwidth management (BWM) server and a first communications device that has a first RAT link to a wireless transmit receive unit (WTRU);
establishing a second internet protocol based tunnel between the BWM server and a second communications device;
establishing a communications interface between the BWM server and a third communications device that has a second RAT link to the WTRU, wherein the first RAT link uses a first RAT and the second RAT link uses a second RAT that is different from the first RAT;
receiving a communication for the WTRU over the second tunnel; and
dividing the communication, by the BWM server, into a first portion for transmission over the first RAT link and a second portion for transmission over the second RAT link.
2. The method of claim 1 , wherein the communication is divided in accordance with one or more radio conditions associated with the first RAT link.
3. The method of claim 1 , wherein the BWM server terminates and reestablishes a tunneling protocol between the first communications device and the third communications device.
4. The method of claim 1 , further comprising transmitting the first portion and the second portion to the WTRU approximately simultaneously.
5. A device comprising a processor configured to:
establish a first internet protocol based tunnel with a first communications device that has a first radio access technology (RAT) link to a wireless transmit receive unit (WTRU);
establish a second internet protocol based tunnel with a second communications device;
establish a communications interface with a third communications device that has a second RAT link to the WTRU, wherein the first RAT link uses a first RAT and the second RAT link uses a second RAT that is different from the first RAT;
receive a communication for the WTRU over the second tunnel;
divide the communication into a first portion and a second portion; and
transmit the first portion over the first RAT link and the second portion over the second RAT link.
6. The device of claim 5 , wherein the communication is divided in accordance with a type of an application communicating with the WTRU.
7. The device of claim 5 , wherein the communication is divided in accordance with respective radio conditions of at least one of the first RAT link and the communications interface.
8. The device of claim 5 , wherein the processor is further configured to perform deep packet inspection.
9. The device of claim 5 , wherein the processor is further configured to add a protocol sequence number to a packet associated with the communication.
10. The device of claim 5 , wherein the second tunnel is a general packet radio service (GPRS) tunneling protocol tunnel.
11. The device of claim 5 , wherein the second tunnel is an internet protocol security tunnel.
12. The device of claim 5 , wherein the first tunnel is a general packet radio service (GPRS) tunneling protocol (GTP) tunnel.
13. The device of claim 5 , wherein the first tunnel is an internet protocol security tunnel.
14. The device of claim 5 , wherein the processor is further configured to process the communication based on Multi-Network Transport Protocol (MNTP).
15. The device of claim 5 , wherein the second communications device is a core network device.
16. The device of claim 5 , wherein the third communications device is a wireless fidelity (WiFi) access point.
17. The device of claim 5 , wherein the second communications device is a local gateway (LGW).
18. The device of claim 5 , wherein the first communications device is at least one of a Home NodeB (HNB) or a Home eNodeB (HeNB).
19. The device of claim 5 , wherein the first portion comprises substantially an entirety of the communication.
20. The device of claim 5 , wherein the first portion and the second portion are transmitted approximately simultaneously.
