Abstract

A device that implements adaptive on-demand tethering may include at least one processor circuit. The at least one processor circuit may be configured to monitor at least a first connection quality value associated with a first network connection of the device to a network. The at least one processor circuit may be further configured to receive information regarding a second connection quality value associated with a second network connection of another device. The at least one processor circuit may be further configured to initiate a tethering connection with the another device based at least in part on a comparison of the first connection quality value and the second connection quality value. The at least one processor circuit may be further configured to connect to the network through the second network connection of the another device via the tethering connection based at least in part on the comparison.

Claims

1. A computer-implemented method for adaptive on-demand tethering, the method comprising:

connecting to a network via a first network connection;

monitoring at least a first attribute of the first network connection;

exchanging, with a proximal device, authentication information received from a service provider;

initiating a tethering connection with the proximal device based at least in part on the monitoring of the first attribute and the exchanging;

determining, in conjunction with the proximal device, whether the proximal device will operate as a host device or a client device for the tethering connection;

creating a first wireless network to be connected to by the proximal device for the tethering connection when the proximal device is determined to operate as the client device for the tethering connection, otherwise connecting to a second wireless network created by the proximal device for the tethering connection when the proximal device is determined to operate as the host device for the tethering connection; and

connecting to the network through a second network connection of the proximal device via the tethering connection based at least in part on the monitoring of the first attribute.

2. The method of claim 1, wherein initiating the tethering connection with the proximal device based at least in part on the monitoring of the first attribute comprises initiating the tethering connection with the proximal device over a local wireless connection when the first attribute of the first network connection fails to satisfy one or more criteria.

3. The method of claim 2, wherein exchanging, with the proximal device, the authentication information received from the service provider further comprises:

exchanging the authentication information received from the service provider and connection configuration information for the tethering connection with the proximal device over the local wireless connection prior to monitoring the first attribute of the first network connection.

4. The method of claim 3, further comprising:

authenticating with the service provider via the network; and

receiving the authentication information from the service provider prior to exchanging the authentication information received from the service provider with the proximal device, the authentication information received from the service provider being different than another authentication information received from the proximal device during the exchanging.

5. The method of claim 3, wherein the local wireless connection comprises a Bluetooth connection that is separate from the first network connection and the network comprises an Internet.

6. The method of claim 2, further comprising:

receiving, from the proximal device via the local wireless connection, a second attribute of the second network connection; and

initiating the tethering connection with the proximal device when the first attribute of the first network connection fails to satisfy the one or more criteria and the second attribute of the second network connection satisfies the one or more criteria.

7. The method of claim 2, further comprising:

monitoring the first attribute of the first network connection while connected to the network through the second network connection of the proximal device via the tethering connection;

terminating the tethering connection when the first attribute of the first network connection satisfies the criteria; and

reconnecting to the network via the first network connection when the first attribute of the first network connection satisfies the criteria.

8. The method of claim 2, wherein the first attribute of the first network connection comprises at least one of:

a signal strength, a data rate, a bit error rate, a data usage, or a billing amount associated with the first network connection, and the one or more criteria comprises at least one of a minimum signal strength, a minimum data rate, a minimum bit error rate, a maximum data usage, or a maximum billing amount.

9. The method of claim 1, wherein the proximal device is determined to operate as the client device for the tethering connection.

10. A device comprising:
