Abstract

A method, apparatus, and system for application controlled network selection between a broadband network and a narrowband network include operating an application with an end device with a narrowband connection to the end device; acquiring a source broadband connection comprising a source broadband network address; negotiating a peer-to-peer broadband connection with the end device utilizing the narrowband connection to communicate the source broadband network address; utilizing the peer-to-peer broadband connection for data associated with the application responsive to successful negotiating; and managing the peer-to-peer broadband connection using the narrowband connection as a control channel therefor. The narrowband connection can include Digital Mobile Radio (DMR), Land Mobile Radio (LMR), Project 25 (P25), Terrestrial Trunked Radio (TETRA), or the like.

Claims

1. A method for application controlled network selection between a broadband network and a narrowband network, the method comprising:

operating, by a source device, an application that communicates with an end device through a narrowband connection;

acquiring, by the source device, a source broadband connection comprising a source broadband network address;

establishing, by the source device, a peer-to-peer broadband connection with the end device using the narrowband connection to communicate the source broadband network address to the end device;

using, by the source device, the established peer-to-peer broadband connection for communicating data associated with the application to the end device;

after the peer-to-peer broadband connection is established, maintaining, by the source device, the narrowband connection for a duration of the peer-to-peer broadband connection and managing, by the source device, the established peer-to-peer broadband connection using the narrowband connection as a control channel for the peer-to-peer broadband connection;

creating a tunnel over the established peer-to-peer broadband connection; and

transferring, by the source device, the data with an address from the narrowband connection encapsulated in the tunnel over the established peer-to-peer broadband connection.

2. The method of claim 1, wherein the narrowband connection comprises one of Digital Mobile Radio (DMR), Land Mobile Radio (LMR), Project 25 (P25), or Terrestrial Trunked Radio (TETRA), and the source broadband connection comprises one of WI-FI, BLUETOOTH, WIMAX, 3G, or Long Term Evolution (LTE).

3. The method of claim 1, further comprising:

utilizing, by the source device, the narrowband connection for the data associated with the application responsive to unsuccessful negotiating.

4. The method of claim 1, further comprising:

operating, by the source device, a plurality of applications comprising the application; and

utilizing, by the source device, one of the narrowband connection and the established peer-to-peer broadband connection based on a priority level on a per application basis.

5. The method of claim 1, wherein the managing comprises:

receiving, by the source device, a notification from the end device on the narrowband network if the peer-to-peer broadband connection becomes unavailable at the end device;

providing, by the source device, a notification to the end device on the narrowband network if the source broadband connection becomes unavailable; and

using, by the source device, the narrowband connection for the data associated with the application responsive to the receiving or the providing.

6. The method of claim 5, wherein the managing further comprises:

determining, by the source device, the established peer-to-peer broadband connection is available subsequent to the using the narrowband connection; and

using, by the source device, the established peer-to-peer broadband connection for the data associated with the application.

7. The method of claim 1, further comprising:

performing a firewall traversal on the established peer-to-peer broadband connection.

8. The method of claim 1, further comprising:

providing, by the source device, the source broadband network address to a presence notifier server; and

obtaining, by the source device, a target broadband network address of the end device from the presence notifier server.

9. The method of claim 8, further comprising:

utilizing the presence notifier server to form the peer-to-peer broadband connection.

10. A method for application controlled network selection between a broadband network and a narrowband network, the method comprising:

operating, by a source device, an application that communicates with an end device through a narrowband connection;

acquiring, by the source device, a source broadband connection comprising a source broadband network address;

establishing, by the source device, a peer-to-peer broadband connection with the end device using the narrowband connection to communicate the source broadband network address to the end device;

using, by the source device, the established peer-to-peer broadband connection for communicating data associated with the application to the end device;

after the peer-to-peer broadband connection is established, maintaining, by the source device, the narrowband connection for a duration of the peer-to-peer broadband connection and managing, by the source device, the established peer-to-peer broadband connection using the narrowband connection as a control channel for the peer-to-peer broadband connection;

providing, by the source device, the source broadband network address to the end device via the narrowband connection;

requesting, by the source device, a status of a target broadband connection for the end device;

receiving, by the source device, a target broadband network address of the end device if the end device has the target broadband connection enabled;

providing, by the source device, an update to the end device responsive to a change in the source broadband network address; and

receiving, by the source device, an update from the end device responsive to a change in the target broadband network address.

11. A method for application controlled network selection between a broadband network and a narrowband network, the method comprising:

operating, by a source device, an application that communicates with an end device through a narrowband connection;

acquiring, by the source device, a source broadband connection comprising a source broadband network address;

establishing, by the source device, a peer-to-peer broadband connection with the end device using the narrowband connection to communicate the source broadband network address to the end device;

using, by the source device, the established peer-to-peer broadband connection for communicating data associated with the application to the end device;

after the peer-to-peer broadband connection is established, maintaining, by the source device, the narrowband connection for a duration of the peer-to-peer broadband connection and managing, by the source device, the established peer-to-peer broadband connection using the narrowband connection as a control channel for the peer-to-peer broadband connection; and

closing, by the source device, the established peer-to-peer broadband connection responsive to one of a timeout or a message from the end device on the narrowband network.
