Abstract

In systems and methods of transferring information to a wireless device, a first portion of information is received and stored in a memory of the wireless device, and the first portion is presented while a second portion of the information is received. A presentation rate at which the first portion is presented is determined, and a time until the first portion is completely presented is determined based on the presentation rate and a size of the first portion. A number of times that a packet retransmission criteria is met is determined, and a maximum permitted number of packet retransmissions is adjusted based on the time until the first portion is completely presented and the number of times that the packet retransmission criteria is met.

Claims

1. A method of transferring a plurality of data packets to a wireless device, comprising:

receiving and storing a first portion of the plurality of data packets in a memory of the wireless device;

presenting the stored first portion while receiving a second portion of the plurality of data packets;

determining a presentation rate at which the first portion is presented;

determining a time until the first portion is completely presented based on the presentation rate and a size of the first portion;

determining a number of times that a packet retransmission criteria is met,

wherein the packet retransmission criteria comprises a maximum permitted number of packet retransmissions of the plurality of data packets; and

adjusting the maximum permitted number of packet retransmissions based on the time until the first portion is completely presented and the number of times that the packet retransmission criteria is met.

2. The method of claim 1, wherein adjusting the maximum permitted number of packet retransmissions further comprises:

increasing the maximum permitted number of packet retransmissions when the time until the first portion is completely presented meets a first criteria and the number of times that the packet retransmission criteria is met meets a second criteria.

3. The method of claim 2, wherein adjusting the maximum permitted number of packet retransmissions further comprises:

decreasing the maximum permitted number of packet retransmissions when the time until the first portion is completely presented meets a third criteria and the number of times that the packet retransmission criteria is met meets a fourth criteria.

4. The method of claim 3, wherein the first criteria comprises a first time until the first portion is completely presented, and wherein the third criteria comprises a second time until the first portion is completely presented which is larger than the first criteria.

5. The method of claim 3, wherein the third criteria comprises a first number of times that that the packet retransmission criteria is met, and wherein the fourth criteria comprises a second number of times that the packet retransmission criteria is met which is smaller than the third criteria.

6. The method of claim 3, wherein adjusting further comprising:

making no change in the maximum permitted number of packet retransmissions when the number of times that the packet retransmission criteria is met meets a fifth criteria which is smaller than the fourth criteria.

7. The method of claim 1, further comprising:

determining a packet retransmit time; and

determining an upper limit for the maximum permitted number of packet retransmissions based on the packet retransmit time.

8. The method of claim 1, wherein determining a number of times that packet retransmission criteria is met further comprises determining that a packet of the first portion has been lost.

9. The method of claim 8, further comprising determining a number of times which the wireless device sends a message to indicate that a packet of the first portion has been lost.

10. The method of claim 1, further comprising:

determining a wireless communication link load of a communication link over which the first portion and the second portion are received by the wireless device; and

adjusting the maximum permitted number of packet retransmissions based on the time until the first portion is completely presented, the number of times that packet retransmission criteria has been met, and the wireless communication link load.

11. The method of claim 10, wherein adjusting the maximum permitted number of packet retransmissions further comprises:

determining the wireless communication link load of the communication link over which the first portion and the second portion are received by the wireless device; and

increasing the maximum permitted number of packet retransmissions when the time until the first portion is completely presented meets a first criteria, the number of times that packet retransmission criteria is met meets a second criteria, and the wireless communication link load.

12. The method of claim 1, further comprising:

determining a backhaul load of a communication link over which the first portion and the second portion are transported; and

adjusting the maximum permitted number of packet retransmissions based on the time until the first portion is completely presented, the number of times that packet retransmission criteria has been met, and the backhaul load.

13. A system for transferring a plurality of data packets to a wireless device, comprising:

a processing node configured to determine a presentation rate at which a first portion of the plurality of data packets stored on a wireless device is presented while a second portion of the plurality of data packets is received;

determine a time until the first portion is completely presented based on the presentation rate and a size of the first portion;

determine a number of times that a packet retransmission criteria is met, wherein the packet retransmission criteria comprises a maximum permitted number of packet retransmissions of the plurality of data packets; and

adjust the maximum permitted number of packet retransmissions based on the time until the first portion is completely presented and the number of times that the packet retransmission criteria is met.

14. The system of claim 13, wherein the processing node is further configured to increase the maximum permitted number of packet retransmissions when the time until the first portion is completely presented meets a first criteria and the number of times that the packet retransmission criteria is met meets a second criteria.

15. The system of claim 14, wherein the processing node is further configured to decrease the maximum permitted number of packet retransmissions when the time until the first portion is completely presented meets a third criteria and the number of times that the packet retransmission criteria is met meets a fourth criteria.

16. The system of claim 15, wherein the third criteria comprises a first number of times that that the packet retransmission criteria is met, and wherein the fourth criteria comprises a second number of times that the packet retransmission criteria is met which is smaller than the third criteria.

17. The system of claim 15, wherein the processing node is further configured to make no change in the maximum permitted number of packet retransmissions when the number of times that the packet retransmission criteria is met meets a fifth criteria which is smaller than the fourth criteria.

18. The system of claim 13, wherein the processing node is further configured to determine a packet retransmit time;

and

determine an upper limit for the maximum permitted number of packet retransmissions based on the packet retransmit time.

19. The system of claim 13, wherein the processing node is further configured to determine that a packet of the first portion has been lost.

20. The system of claim 19, wherein the processing node is further configured to determine a number of times which the wireless device sends a message to indicate that a packet of the first portion has been lost.

21. The system of claim 15, wherein the third criteria comprises a first number of times that the packet retransmission criteria is met, and wherein the fourth criteria comprises a second number of times that the packet retransmission criteria is met which is smaller than the third criteria.
