Abstract

A system, method and device are disclosed for managing bandwidth in content delivery from a push content server to a wireless device. The system may include: a content server configurable to deliver content to the wireless device; a processor for controlling operation of the server; a communications subsystem coupled to the processor; a memory coupled to the processor; and a storage device coupled to the processor. The content server may include a module for managing bandwidth in content delivery from the content server to the wireless device, the module being configured to cause the content server to: record a policy for the delivery of content to the wireless device; initiate content delivery to the wireless device; evaluate the policy to determine whether new content for delivery is deliverable to the wireless device; deliver content when the policy is satisfied; and decline delivery of content when the policy is not satisfied.

Claims

1. A system for managing bandwidth in content delivery from a push content server to a wireless device, the system comprising:

a content server configurable to deliver push content to the wireless device,

a processor for controlling operation of the server;

a communications subsystem coupled to the processor for communicating with a communications network;

a memory coupled to the processor; and

a storage device coupled to the processor;

the content server including one or more modules for managing bandwidth in content delivery from the content server to the wireless device, the one or more modules being configured to cause the content server to;

record a policy for the delivery of content to the wireless device;

initiate content delivery to the wireless device;

evaluate the policy to determine whether new content for delivery is deliverable to the wireless device;

deliver content when the policy is satisfied; and

decline delivery of content when the policy is not satisfied.

2. The system of claim 1, wherein:

the policy is recorded to permit delivery of content via a high cost connection when bandwidth usage is within a predetermined bandwidth range over a predetermined period of time, and

the policy is recorded to decline delivery of content via a high cost connection when bandwidth usage is outside of a predetermined bandwidth range over a predetermined period of time; and

the content is delivered to the wireless device via at least one of a non-carrier communication mode and tethered mode of transmission when bandwidth usage is outside of the predetermined bandwidth range.

3. The system of claim 2, wherein the content includes media files that have a relatively high transmission cost.

4. The system of claim 1, wherein the policy is set for a group of users sharing pooled bandwidth, and the one or more modules cause the server to evaluate whether additional bandwidth is available from the pool when the policy has been exceeded, calculate a new maximum bandwidth allotment using a formula based on the size of the remaining content, and communicate the new allotment to the wireless device.

5. The system device of claim 1, wherein the policy is based on at least one of:

bandwidth available, bandwidth cost, type of content to be transmitted, size of the content to be transmitted and mode of transmission to the wireless device, and the mode of transmission is at least one of;

carrier, non-carrier, physically tethered and roaming.

6. A method for managing bandwidth in content delivery from a push content server to a wireless device, the method comprising:

recording a policy, on at least one of the content server and the wireless device, for delivery of content to the wireless device;

initiating content delivery to the wireless device;

evaluating the policy to determine whether new content for delivery is deliverable to the wireless device;

delivering content to the wireless device when the policy is satisfied; and

declining delivery of content when the policy is not satisfied.

7. The method of claim 6, wherein:

the policy is recorded to permit delivery of content via a high cost connection when bandwidth usage is within a predetermined bandwidth range over a predetermined period of time, and

the policy is recorded to decline delivery of content via a high cost connection when bandwidth usage is outside of a predetermined bandwidth range over a predetermined period of time;

the content is delivered to the wireless device via at least one of a non-carrier communication mode and tethered mode of transmission when bandwidth usage is outside of the predetermined bandwidth range;

declining is performed by one of the server and the wireless device; and

the method further comprises physically connecting the wireless device to a networked content source when the tethered mode of transmission is used.

8. The method of claim 7, wherein content is pushed to the wireless device without user intervention, and the content includes media files that have a relatively high transmission cost.

9. The method of claim 6, wherein the policy is set for a group of users sharing pooled bandwidth, and further comprising evaluating whether additional bandwidth is available from the pool when the policy has been exceeded, calculating a new maximum bandwidth allotment using a formula based on the size of the remaining content, and communicating the new allotment to the wireless device.

10. The method of claim 6, wherein the policy is based on at least one of:

bandwidth available, bandwidth cost, type of content to be transmitted, size of the content to be transmitted and mode of transmission to the wireless device, and the mode of transmission is at least one of;

carrier, non-carrier, physically tethered and roaming.

11. The method of claim 6, wherein the policy is recorded to permit delivery of content via a high cost connection when the content has a size within a predetermined range, and the policy is set to decline delivery of content via a high cost connection when the content size is outside a predetermined range.

12. The method of claim 6, wherein the policy limits delivery based on at least one of the type of content and the source of the content.

13. The method of claim 6, further comprising providing a notification on a display of the user device about the status of content delivery, and notifying the server when content delivery is declined.

14. The method of claim 6, further comprising queuing the content for later delivery after content delivery is declined, and performing at least one of removing, transferring and deleting the content from the queue when the wireless device is connected via a low cost connection.

15. The method of claim 6, further comprising reducing the rate of delivery of content before declining delivery of content.

16. A wireless device for managing bandwidth in content delivery from a push content server to the wireless device comprising:

a processor for controlling operation of the wireless device;

a first input device coupled to the processor for accepting an input;

at least one display device coupled to the processor for communicating an output to the user;

a communications subsystem coupled to the processor for communicating with a communications network, the communications network including a at least one content server configurable for delivering push content to the wireless device;

a memory coupled to the processor; and

a storage device coupled to the processor;

the wireless device including one or more modules for managing bandwidth in content delivery from a push content server to the wireless device, the one or more modules being configured to cause the wireless device to;

record a policy for the delivery of content to the wireless device;

initiate content delivery to the wireless device;

evaluate the policy to determine whether new content for delivery is deliverable to the wireless device;

accept delivery of content when the policy is satisfied; and

decline delivery of content when the policy is not satisfied.

17. The wireless device of claim 16, wherein:
