Abstract

The present disclosure is directed to methods and system for managing communication of packets. A transceiver node receives a plurality of IP data packets from an internet protocol (IP) network. The transceiver node separates the IP data packets into a first set and a second set of IP data packets, according to channel conditions of a cellular network and a wireless local area network (WLAN). The transceiver node transmits, to a user device, the first set of IP data packets using a cellular network protocol of the cellular network and the second set of IP data packets using a WLAN protocol of the WLAN, causing the user device to aggregate the first set of IP data packets transmitted using the cellular network protocol with the second set of IP data packets transmitted using the WLAN protocol.

Claims (35)

1. A method of managing communication of packets, the method comprising:

receiving, by a transceiver node, a plurality of internet protocol (IP) data packets from an IP network;

separating, by the transceiver node, the plurality of IP data packets into a first set of IP data packets and a second set of IP data packets, according to channel conditions of a cellular network and a wireless local area network (WLAN); and

transmitting, by the transceiver node to a user device, the first set of IP data packets using a cellular network protocol of the cellular network and the second set of IP data packets using a WLAN protocol of the WLAN, causing the user device to:

receive the first set of IP data packets through the cellular network and the second set of IP data packets through the WLAN, and

combine the first set of IP data packets transmitted using the cellular network protocol and the second set of IP data packets transmitted using the WLAN protocol into a combined set of IP data packets.

2. The method of claim 1 , wherein the first set of IP data packets is transmitted simultaneously with the second set of IP data packets.

3. The method of claim 1 , wherein each of the first set of IP data packets and the second set of IP data packets is transmitted in sequence to the user device.

4. The method of claim 1 , wherein the transceiver node uses a hash function to separate the IP data packets, the hash function associated with at least one of source IP address, source port number, destination IP address, destination port number, or protocol.

5. The method of claim 1 , further comprising determining whether each of the plurality of IP data packets belongs to a flow for which there was at least another packet forwarded to the cellular network or the WLAN.

6. The method of claim 5 , further comprising: responsive to determining that an IP data packet belongs to the flow for which there was the at least another packet forwarded to the cellular network or the WLAN, transmitting the IP data packet through the same network as the at least another packet.

7. The method of claim 1 , wherein the channel conditions are detected according to measurements of channel activity statistics obtained from the cellular network and the WLAN.

8. The method of claim 7 , wherein the channel activity statistics comprise at least one of packet error rates, data rates, MCS values, ACK.NACK, or channel loading data.

9. The method of claim 1 , further comprising comparing a channel condition of the cellular network with a channel condition of the WLAN.

10. The method of claim 1 , wherein separating the plurality of IP data packets comprises distributing more IP data packets to one of the first set of IP data packets and the second set of IP data packets associated with a better channel condition.

11. A method, comprising:

providing, by an application on a user device, a plurality of internet protocol (IP) data packets;

separating, by the user device, the plurality of IP data packets into a first set of IP data packets and a second set of IP data packets, according to channel conditions of a cellular network and a wireless local area network (WLAN); and

transmitting, from the user device to a transceiver node, the first set of IP data packets using a cellular network protocol of the cellular network and the second set of IP data packets using a WLAN protocol of the WLAN, causing the transceiver node to:

receive the first set of IP data packets through the cellular network and the second set of IP data packets through the WLAN, and

combine the first set of IP data packets transmitted using the cellular network protocol and the second set of IP data packets transmitted using the WLAN protocol into a combined set of IP data packets.

12. The method of claim 11 , wherein the first set of IP data packets are transmitted to an LTE interface of the transceiver node via a Data Radio Bearer (DRB).

13. The method of claim 11 , wherein the first set of IP data packets is transmitted simultaneously with the second set of IP data packets.

14. The method of claim 11 , further comprising:

transmitting the second set of IP data packets to a WLAN access point interface in the WLAN; and

transmitting the second set of IP data packets from the WLAN access point interface to the transceiver node via an IPsec tunnel.

15. The method of claim 12 , wherein the LTE interface comprises a Packet Data Convergence Protocol (PDCP) circuit, a Radio Link Control (RLC) circuit, and a media access control/physical layer (MAC/PHY) circuit.

16. A method, comprising:

receiving, from a user device at a transceiver node, a first set of internet protocol (IP) data packets through a cellular network;

receiving, from the user device at the transceiver node, a second set of IP data packets through a wireless local area network (WLAN);

combining, at the transceiver node, the first set of IP data packets and the second set of IP data packets into a third set of IP data packets; and

transmitting, by the transceiver node, the third set of IP data packets to an IP network.

17. The method of claim 16 , wherein the first set of IP data packets is received simultaneously with the second set of IP data packets.

18. The method of claim 16 , wherein each of the first set of IP data packets and the second set of IP data packets are received in sequence.

19. The method of claim 16 , wherein combining the first set of IP data packets and the second set of IP data packets starts before receipt of all of the first set of IP data packets and the second set of IP data packets at the transceiver node.
