Abstract

In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for traffic aggregation on multiple Wide Area Network (WAN) backhauls and multiple distinct Local Area Network (LAN) networks; for traffic load balancing on multiple WAN backhauls and multiple distinct LAN networks; and for performing self-healing operations utilizing multiple WAN backhauls serving multiple distinct LAN networks. For example, in one embodiment, a first Local Area Network LAN access device is to establish a first LAN; a second LAN access device is to establish a second LAN; a first Wide Area Network WAN backhaul connection is to provide the first LAN access device with WAN connectivity; a second WAN backhaul connection to provide the second LAN access device with WAN connectivity; a management device is communicatively interfaced with each of the first LAN access device, the second LAN access device, the first WAN backhaul connection, and the second WAN backhaul connection; and the management device routes a first portion of traffic originating from the first LAN over the first WAN backhaul connection and routes a second portion of the traffic originating from the first LAN over the second WAN backhaul connection.

First claim

The invention claimed is:

1 . A femtocell base station comprising:
a first interface that couples to a first mobile cellular device in accordance with a first cellular standard; a second interface that couples to a first wireless backhaul, the first wireless backhaul being coupled to a cellular base station in accordance with the first cellular standard; a third interface that couples to a second wireless backhaul, the second wireless backhaul being coupled to the cellular base station in accordance with a second cellular standard; and a network manager that is coupled to the second and third interfaces, the network manager balances traffic from the first mobile cellular device such that a first portion of traffic from the mobile cellular device is directed to the first wireless backhaul and a second portion of traffic from the mobile cellular device is directed to the second wireless backhaul.

2 . The femtocell base station of claim 1 wherein the first cellular standard is LTE.

3 . The femtocell base station of claim 1 wherein the second cellular standard is LTE.

4 . The femtocell base station of claim 1 wherein the network manager balances traffic based at least in part on a soft failure on the first wireless backhaul.

5 . The femtocell base station of claim 1 wherein the network manager balances traffic based at least in part on a hard failure of the first wireless backhaul.

6 . The femtocell base station of claim 1 wherein the network manager balances traffic using a re-route operation of traffic from the first wireless backhaul to the second wireless backhaul.

7 . The femtocell base station of claim 1 wherein the second and third interfaces are integrated into a single interface.

8 . The femtocell base station of claim 1 wherein the first mobile cellular device is a cellular telephone.

9 . The femtocell base station of claim 1 further comprising a fourth interface that couples to a second mobile cellular device in accordance with the first cellular standard.

10 . The femtocell base station of claim 9 wherein the traffic being load balanced by the network manager comprises traffic from the first and second mobile cellular devices.

11 . The femtocell base station of claim 10 wherein the second mobile cellular device is a cellular telephone.

12 . A base station comprising:
a first interface that couples to a first mobile cellular device in accordance with a first cellular standard, the first mobile cellular device being within a cellular network of the base station; a second interface that couples to a first wireless backhaul, the first wireless backhaul communicating in accordance with the first cellular standard; a third interface that couples to a second wireless backhaul, the second wireless backhaul communicating in accordance with a second cellular standard; and a network manager that is coupled to the second and third interfaces, the network manager transmits traffic from the first mobile cellular device on the first wireless backhaul and the second wireless backhaul, the first and second wireless backhauls being correlated.

13 . The base station of claim 12 wherein the base station is a femtocell base station.

14 . The base station of claim 12 wherein the base station is a small cell base station.

15 . The base station of claim 12 wherein the first and second wireless backhauls are coupled to another base station.

16 . The base station of claim 12 wherein the traffic is distributed between the first and second wireless backhauls based at least in part on a soft failure on the first wireless backhaul.

17 . The base station of claim 12 wherein the first wireless backhaul is a cellular backhaul.

18 . The base station of claim 17 wherein the first wireless backhaul is a LTE backhaul.

19 . The base station of claim 12 wherein the first and second interfaces are integrated into a single interface.
