Abstract

A system and method may use mm-wave superspots to download high volumes of data to a moving or stationary mobile device traveling along a travel route that the moving mobile device is traveling. A macrocell in communication with the mobile device may predict the route that the mobile device is traveling, such as via GPS location, moving speed and direction, map information, etc. Alternatively, the route being taken may be determined by wireless communication, such as between the mobile device and a macrocell and/or superspot. The macrocell and/or superspot may determine whether (1) there are any mm-wave superspots along the predicted or known route that the mobile device is taking; (2) there is any data that is requested or remaining to download to the moving mobile device; and/or (3) the received signal quality, channel conditions, and/or macrocell traffic to the mobile device are favorable for superspot downloading.

Claims

1. A computer-implemented method of downloading data to a mobile device comprising:

receiving, at a first entity, a request for a data download to a mobile device, the first entity being configured to transmit and receive via a first frequency;

wirelessly controlling, at the first entity, a staging of the data download at a second entity configured to transmit and receive via a second frequency, the second frequency being different than the first frequency;

wirelessly instructing the mobile device to activate a transceiver configured for the second frequency; and

wirelessly directing, from the first or second entity, the data download to be transmitted to the mobile device from the second entity via the second frequency while the mobile device maintains a wireless connection with the first entity via the first frequency.

2. The method of claim 1, further comprising:

providing a second entity proximity list to the mobile device via the first frequency.

3. The method of claim 1 further comprising:

pre-staging data at a second entity based on a predicted proximity of the mobile device to the second entity.

4. The method of claim 1 further comprising:

receiving, from the mobile device, signal quality measurement updates related to the second entity via the first frequency.

5. The method of claim 4, wherein directing the data download to be transmitted to the mobile device is triggered when the signal quality measurement updates are above a predetermined threshold.

6. The method of claim 5, wherein the signal quality measurement updates are based upon a signal received from a beacon transmitting from the second entity via the first frequency.

7. A network device that facilitates data downloads to mobile devices, the network device comprising:

a processor configured to;

receive a request for a mobile device data download from a network associated with the network device, the network device being configured to transmit and receive via a first frequency and is in wireless communication with the mobile device via the first frequency;

stage the mobile device data download at a second entity configured to transmit and receive via a second frequency, the second frequency being different from the first frequency;

wirelessly instruct the mobile device to activate a transceiver located on the mobile device that is configured for the second frequency; and

cause the mobile device data download to be transmitted to the mobile device via the second frequency while simultaneously maintaining the wireless communication between the mobile device and the network device via the first frequency.

8. The network device of claim 7, wherein the processor is further configured to determine an imminent proximity of the mobile device to the second entity based upon reports of the mobile device'"'"'s location and trajectory received via the first frequency, and the staging of the mobile device data download is based upon the imminent proximity.

9. The network device of claim 7, wherein the processor is further configured to determine that the mobile device has entered a coverage area of the second entity based upon reports of a beacon signal transmitted from the second entity via the first frequency, and the causing of the mobile device data download to be transmitted is based upon the mobile device entering the coverage area of the second entity.

10. The network device of claim 7, wherein the processor is further configured to maintain a database, the database comprising radio parameters for one or more wireless beams of the second entity.

11. The network device of claim 10, wherein the processor is further configured to update the database using reports generated by the mobile device based upon transmissions of the mobile device on the second frequency.

12. The network device of claim 10, wherein the processor is further configured to update the database using reports generated by an RF sensing radio receiving transmissions of the second entity on the second frequency.

13. A computer-implemented method of data downloading to a mobile device, the method comprising:

(a) wirelessly communicating with a first entity via a first frequency by the mobile device;

(b) turning on a transceiver operating on a second frequency that is different from the first frequency at the mobile device when movement of the mobile device is expected to bring the mobile device within range of a second entity and there is data marked for download to the mobile device; and

(c) receiving data packets from the second entity via the transceiver on the mobile device operating at the second frequency when the mobile device is within coverage of the second entity and simultaneously in wireless communication with the first entity via a second transceiver operating at the first frequency.

14. The method of claim 13, wherein the received data packets are transmitted from the second entity when signal quality, channel conditions, and/or macrocell traffic are confirmed to support dual mode operation on the mobile device.

15. The method of claim 13, wherein the first frequency is used for cellular or Long Term Evolution (LTE) wireless communications and the second frequency is a mm-wave frequency.
