Abstract

A receiver of network data dynamically filters packets by packet type from a network device CPU based on usage information, such as time, day, location, and feature (e.g., “video” or “application”) selection.

Claims

1. A receiver of network data comprising:

at least one non-transitory computer storage medium with instructions which when executed by at least one processor configure the processor for;

causing the receiver to filter received network packets by packet type from a network device central processing unit (CPU) based on dynamic usage information, such that the CPU receives only some packets received by the receiver from at least a first source but not all packets from at least the first source according to the usage information, wherein the usage information by which packets are filtered is established by time of day, and/or day of the week, and/or physical location of the network device, wherein the network packets are filtered by packet type according to the usage information at least in part based on a respective packet type indicators associated with received respective network packets, wherein the respective packet type indicators respectively indicate packet types for their associated respective network packet;

responsive to a user selecting a “

video”

feature, pass video packets received by the receiver to the CPU but not pass, from the receiver to the CPU, binary application packets received by the receiver, and responsive to a user changing to an “

application”

feature selection, pass binary application packets but not video packets.

2. The receiver of claim 1, wherein the usage information includes time.

3. The receiver of claim 1, wherein the usage information includes day of the week.

4. The receiver of claim 1, wherein the usage information includes physical location of the network device.

5. The receiver of claim 1, wherein the usage information includes feature selection.

6. The receiver of claim 1, wherein the receiver is implemented in the network device.

7. The receiver of claim 6, wherein the instructions when executed by the processor configure the processor to wirelessly receive packets from the network and the network device is battery powered.

8. A method comprising:

receiving iterative usage information pertaining to a network device;

based on the usage information, determining at least one desired packet type; and

passing, from a packet receiver of the network device to a central processing unit (CPU) of the network device, only the packets determined to be of the at least one desired packet type, wherein the usage information is established at least by physical location of the network device;

wherein responsive to a user selection of a “

video”

feature, the desired packet type includes video packets but not binary application packets, wherein responsive to a user selection of an “

application”

feature, the desired packet type includes binary application packets but not video packets.

9. The method of claim 8, wherein the usage information includes time of day.

10. The method of claim 8, wherein the usage information includes day of the week.

11. The method of claim 8, wherein the usage information includes user preference as indicated by input received from a user input device.

12. The method of claim 11, wherein the user preference is a “

video”

feature or an “

application”

feature of the network device.

13. The method of claim 8, wherein at least a first packet type is always passed to the CPU regardless of the usage information.

14. The method of claim 13, wherein the first packet type is an emergency packet type.

15. The method of claim 8, wherein the CPU executes the receiving and determining acts.

16. The method of claim 8, wherein the packet receiver executes the receiving and determining acts.

17. The method of claim 8, wherein all packets that are passed are of one packet type.

18. A device, comprising:

a central processing unit (CPU);

a packet receiver accessible to the processor; and

storage accessible to the processor and bearing instructions executable by the processor to;

based on non-static usage information pertaining to the device, determine at least one desired packet type; and

pass, from the packet receiver to the CPU, only packets received over a network that are determined to be of the at least one desired packet type, wherein the usage information is established at least by a current physical location of the device;

wherein responsive to a user selection of a “

video”

feature, the desired packet type includes video packets but not binary application packets, wherein responsive to a user selection of an “

application”

feature, the desired packet type includes binary application packets but not video packets.

19. The device of claim 18, wherein the usage information is further established at least by time of day and/or day of the week.
