Abstract

Methods and apparatus for content delivery to a mobile device. A method is provided for receiving content in a wireless data network. The method includes initiating a content download over a first connection that supports a first data rate, wherein the content has a selected quality level, and establishing a second connection that supports a second data rate. The method also includes comparing the first data rate to the second data rate, and processing the content download based on the result of said comparing.

Claims

1. A method for transmitting content, the method comprising:

encoding content at multiple rates to create a plurality of rate encoded copies;

establishing a wireless connection with a device using a first network of a first type having a first data rate capability;

selecting a rate encoded copy of the content to transmit to the device based on the first data rate capability;

initiating transmitting the selected rate encoded copy to a device via the first network;

pausing the transmitting of the selected rate encoded copy if the connection is handed to a second network of a second type having a second data rate capability lower than the first data rate capability;

determining if a contact window is open;

determining if the connection is handed to a third network having a data rate capability at least equal to the first data rate; and

continuing to transmit the selected rate encoded copy via the third network if it is determined that the contact window is open and the third network has a data rate capability at least equal to the first data rate capability.

2. The method of claim 1, wherein the first network comprises a 1×

EV-DO network and the second network comprises a 1×

RTT network.

3. An apparatus for transmitting content in a wireless data network, the apparatus comprising:

means for encoding content at multiple rates to create a plurality of rate encoded copies;

means for establishing a wireless connection with a device using a first network of a first type having a first data rate capability;

means for selecting a rate encoded copy of the content to transmit to die device based on the first data rate capability;

means for initiating transmitting the selected rate encoded copy to a device via the first network;

means for pausing the transmitting of the selected rate encoded copy if the wireless connection is handed to a second network of a second type having a second data rate capability lower than the first data rate capability;

means for determining if a contact window is open; and

means for determining if the connection is handed to a third network having a data rate capability at least equal to the first data rate; and

means for continuing to transmit the selected rate encoded copy via the third network if it is determined that the contact window is open and the third network has a data rate capability at least equal to the first data rate capability.

4. The apparatus of claim 3, wherein the first network comprises a 1×

EV-DO network and the second network comprises a 1×

RTT network.

5. An apparatus for transmitting content in a wireless data network, the apparatus comprising:

a memory;

a processor coupled to said memory, wherein the processor is configured with processor-executable instructions to perform steps comprising;

encoding content at multiple rates to create a plurality of rate encoded copies;

establishing a wireless connection with a device using a first network of a first type having a first data rate capability;

selecting a rate encoded copy of the content to transmit to the device based on the first data rate capability;

initiating transmitting the selected rate encoded copy to a device via the first network;

determining if the connection is handed to a second network of a second typo having a second data rate capability lower than the first data rate capability;

pausing the transmitting of fire selected rate encoded copy if the wireless connection is handed to a second network of a second type having a second data rate capability lower than the first data rate capability;

determining if a contact window is open; and

determining if the connection is handed to a third network having a data rate capability at least equal to the first data rate; and

continuing to transmit the selected rate encoded copy via the third network if it is determined that the contact window is open and the third network has a data rate capability at least equal to the first data rate capability.

6. The apparatus of claim 5, wherein the first network comprises a 1×

EV-DO network and the second network comprises a 1×

RTT network.

7. A computer program product, comprising:

a non-transitory computer-readable storage media comprising;

at least one instruction for encoding content at multiple rates to create a plurality of rate encoded copies;

at least one instruction for establishing a wireless connection with a device using a first network of a first type having a first data rate capability;

at least one instruction for selecting a rate encoded copy of the content to transmit to the device based on the first data rate capability;

at least one instruction for initiating transmitting the selected rate encoded copy to a device via the first network;

at least one instruction for determining if the connection is handed to a second network of a second type having a second data rate capability lower than the first data rate capability;

at least one instruction for pausing the transmitting of the selected rate encoded copy if the wireless connection is handed to a second network of a second type having a second data rate capability lower than the first data rate capability;

at least one instruction for determining if a contact window is open; and

at least one instruction for determining if the connection is handed to a third network having a data rate capability at least equal to the first data rate; and

at least one instruction for continuing to transmit the selected rate encoded copy via the third network if it is determined that the contact window is open and the third network has a data rate capability at least equal to the first data rate capability.

8. The computer program product of claim 7, wherein the first network comprises a 1×

EV-DO network and the second network comprises a 1×

RTT network.
