## Abstract

A method and system for using low earth orbit satellites to overcome latency is presented. In one embodiment, the method may include establishing a data session using a first channel having a first characteristic different than a second characteristic of a second channel, wherein the first channel is a Low Earth Orit (LEO) channel and wherein the second channel is a Geosynchronous Equatorial Orbit (GEO) channel; determining a type of traffic involved in the data session; determining whether the second channel should be used for the data session; when the second channel should be used for the data session, then switching the data session from the first channel to the second channel; and periodically monitoring the data session to determine whether the second channel should continue to be used for the data session.

## Claims

### Claim 1

A method comprising:
establishing a cellular data backhaul session using a first channel having a first characteristic different than a second characteristic of a second channel, wherein the first channel is a Low Earth Orbit (LEO) channel;
determining a type of traffic involved in the data session;
determining, based on the first characteristic of the first channel and the second characteristic of the second channel and the type of traffic involved, whether the second channel should be used for the data session;
when the second channel should be used for the data session, then switching the data session from the first channel to the second channel; and
periodically monitoring the data session to determine whether the second channel should continue to be used for the data session,
wherein the data session comprises a first part and a second part, and using the first channel for the first part of the data session and using the second channel for the second part of the data session.

### Claim 2 (depends on 1)

The method of claim 1, wherein the establishing a data session using a first channel comprises establishing a data session using an Internet of Things (IoT) channel or a cellular channel.

### Claim 3 (depends on 2)

The method of claim 2, wherein the second channel comprises an IoT channel or a cellular channel or a Geosynchronous Equatorial Orbit (GEO) channel.

### Claim 4 (depends on 3)

The method of claim 3, wherein using the first channel comprises using the LEO, and further comprising communicating with the LEO using a Very Small Aperture Terminal (VSAT).

### Claim 5 (depends on 1)

The method of claim 1, wherein determining, based on the first characteristic of the first channel and the second characteristic of the second channel comprises determining wherein the first characteristic is latency of the first channel and the second characteristic is latency of the second channel.

### Claim 6 (depends on 1)

The method of claim 1, wherein determining, based on the first characteristic of the first channel and the second characteristic of the second channel comprises determining wherein the first characteristic is cost associated with the first channel and the second characteristic is cost associated with the second channel.

### Claim 7 (depends on 1)

The method of claim 1, wherein determining, based on the first characteristic of the first channel comprises determining wherein the first characteristic is an availability of the first channel.

### Claim 8 (depends on 1)

The method of claim 1, wherein determining, based on the first characteristic of the first channel and the second characteristic of the second channel comprises determining wherein the first characteristic or the second characteristic is at least one Quality of Service (QOS) performance metric associated with the data session.

### Claim 9 (depends on 1)

The method of claim 1, wherein using the first channel comprises using signaling data for the first part of the data session and wherein using the second channel comprises using data traffic for the second part of the data session.

### Claim 10

A system comprising:
a terrestrial base station;
a first channel having a first characteristic, the first channel in communication with the terrestrial base station, wherein a data session is established using the first channel;
a second channel having a second characteristic, the second channel in communication with the terrestrial base station, wherein the second channel is a Geosynchronous Equatorial Orbit (GEO) channel and wherein the second characteristic is different from the first characteristic;
wherein a determination is made, based on the first characteristic of the first channel and the second characteristic of the second channel and the type of traffic involved in the data session, whether the second channel should be used for the data session; and when the second channel should be used for the data session, then the data session is switched from the first channel to the second channel and wherein the data session is periodically monitored to determine whether the second channel should continue to be used for the data session; and
wherein the data session comprises a first part and a second part, and using the first channel for the first part of the data session and using the second channel for the second part of the data session.

### Claim 11 (depends on 10)

The system of claim 10, wherein the first channel is a Low Earth Orbit (LEO) channel.

### Claim 12 (depends on 11)

The system of claim 11, wherein the second channel is an IoT channel or a cellular channel.

### Claim 13 (depends on 12)

The system of claim 12, wherein using the first channel comprises using the LEO, and further comprising communicating with the LEO using a Very Small Aperture Terminal (VSAT).

### Claim 14 (depends on 10)

The system of claim 10, wherein the first characteristic is latency of the first channel and the second characteristic is latency of the second channel.

### Claim 15 (depends on 10)

The system of claim 10, wherein the first characteristic is cost associated with the first channel and the second characteristic is cost associated with the second channel.

### Claim 16 (depends on 10)

The system of claim 10, wherein the first characteristic is an availability of the first channel.

### Claim 17 (depends on 10)

The system of claim 10, wherein the first characteristic is at least one Quality of Service (QOS) performance metric associated with the data session.

### Claim 18 (depends on 10)

The system of claim 10, wherein using the first channel comprises using signaling data for the first part of the data session and wherein using the second channel comprises using data traffic for the second part of the data session.
