Abstract

Video content may be delivered in a wireless network based on network load information relating to radio interfaces for the wireless network. A method may include receiving a request, from a set-top box, for video content from the set-top box to the wireless network and determining, based on the load information, whether a portion of the wireless network corresponding to the set-top box is in a first state or a second state. The network may further include transmitting the video content when the portion of the network corresponding to the set-top box is in the first state and delaying transmission of the video content when the portion of the network corresponding to the set-top box is in the second state, until the portion of the network corresponding to the set-top box enters the first state.

Claims

1. A method implemented by one or more devices, the method comprising:

receiving, by the one or more devices, load information regarding network traffic load at radio interfaces for a long term evolution (LTE) network;

receiving, by the one or more devices, a request made by a subscriber, from a set-top box, to the LTE network, for video content;

determining, by the one or more devices and based on the load information, whether a portion of the LTE network corresponding to the subscriber is in a first state or a second state;

transmitting, by the one or more devices over the LTE network, the video content when the portion of the network corresponding to the subscriber is in the first state; and

delaying transmission, over the LTE network and by the one or more devices, the video content when the portion of the network corresponding to the subscriber is in the second state, until the portion of the network corresponding to the subscriber enters the first state.

2. The method of claim 1, where the video content includes video on demand (VoD) content.

3. The method of claim 1, where the portion of the LTE network corresponding to the subscriber includes a base station through which the subscriber connects to the LTE network.

4. The method of claim 3, where determining whether the portion of the LTE network corresponding to the subscriber is in the first state or the second state further includes:

comparing an indication of load of the base station to a threshold and determining that the base station is in the first state when the indication of load is below the threshold and determining that the base station is in the second state when the indication of load is above the threshold.

5. The method of claim 1, further comprising:

pausing transmission of the video content when the portion of the LTE network corresponding to the request enters the second state; and

resuming transmission of the video content when the portion of the LTE network corresponding to the request enters the first state.

6. The method of claim 1, where determining whether the portion of the LTE network corresponding to the LTE is in the first state or the second state further includes:

determining that the portion of the network corresponding to the subscriber is in the first state when a current time falls within a predetermined time window; and

determining that the portion of the network corresponding to the subscriber is in the second state when the current time falls outside the predetermined time window.

7. The method of claim 6, where a start time and an end time defining the predetermined time window are set by a network administrator based on an analysis of historical network traffic.

8. The method of claim 6, where a start time and an end time defining the predetermined time window are set based on automatic analysis of historical network traffic.

9. The method of claim 6, where the predetermined time window corresponds to a period of historically low network load.

10. The method of claim 1, where the determination of whether the portion of the LTE network corresponding to the subscriber is in the first state or the second state is performed by a policy charging and rules function (PCRF) server in the LTE network.

11. The method of claim 1, where receiving the load information further includes:

receiving the load information from base stations or packet data network gateways in the LTE network.

12. A system comprising:

a traffic monitor to store load information regarding network traffic load at radio interfaces for a wireless network; and

a video server to;

receive a request, over the wireless network and from a set-top box, for a video content item for playback by a set-top box, the video server determining, in response to the request, and based on the load information, whether a portion of the wireless network through which the set-top box connects is in a first state or a second state, where the first and second state relate to network load,

transmit the video content item when the portion of the network to which the outdoor broadband unit connects is in the first state, and

delay transmission of the video content item when the portion of the network through which the set-top box connects is in the second state, until the portion of the network enters the first state.

13. The system of claim 12, where the video content item includes content requested as video on demand.

14. The system of claim 12, where the wireless network includes a long term evolution (LTE) network.

15. The system of claim 12, further comprising:

16. The system of claim 15, where the PCRF server determines the state of the portion of the wireless network through which the set-top box connects by comparing the load information to a threshold and determining that the portion of the wireless network through which the set-top box connects is in the first state when the load information is below the threshold and determining that the portion of the wireless network is in the second state when the load information is above the threshold.

17. The system of claim 15, where the PCRF server:
