Abstract

An apparatus and method are provided. The method includes receiving, at an electronic device including a first processor and a second processor, using the first processor, a connection request via a network, and refraining from transmitting the connection request from the first processor to the second processor based at least in part on a determination that the second processor is in a sleep state, and that the connection request is associated with data set as unallowable by the second processor.

Claims

1. A method comprising:

receiving, at an electronic device including a first processor and a second processor, using the first processor, a connection request via a network; and

refraining from transmitting the connection request from the first processor to the second processor based at least in part on a determination that the second processor is in a sleep state, and that the connection request is associated with data set as unallowable by the second processor.

2. The method of claim 1, wherein the connection request is transmitted to the network from another electronic device external to the electronic device.

3. The method of claim 1, wherein the refraining comprises:

determining that the connection request is associated with the data set as unallowable based at least in part on a port number or an internet protocol address to which the data is directed.

4. The method of claim 1, wherein the refraining comprises:

discarding, using the first processor, the connection request.

5. The method of claim 1, further comprising:

transmitting at least part of the connection request from the first processor to the second processor based at least in part on a determination that the connection request is not associated with the data.

6. The method of claim 1, further comprising:

receiving, using the first processor, other data indicative of the connection request via the network prior to the receiving of the connection request; and

transitioning, using the first processor, a radio resource control state from a first state to a second state based at least in part on the receiving of the other data.

7. The method of claim 1, wherein the connection request comprises at least one of a transmission control protocol packet, a user datagram protocol packet, or an internet protocol packet.

8. The method of claim 1, further comprising:

transmitting, using the first processor, other data indicative of a release of the connection request via the network to another electronic device external to the electronic device.

9. The method of claim 1, further comprising:

transmitting, using the first processor, other data indicative of a release of a radio channel to the network.

10. An apparatus comprising:

a first processor to execute an application; and

a second processor to control a communicative connection between the apparatus and a network, the second processor configured to;

receive a connection request via the network; and

refrain from transmitting the connection request to the first processor based at least in part on a determination that the connection request is associated with data set as unallowable by the first processor.

11. The apparatus of claim 10, wherein the second processor is configured to:

perform the refraining further based on a determination that the first processor is in a sleep state.

12. The apparatus of claim 10, wherein the second processor is configured to:

transmit at least part of the connection request to the first processor based at least in part on a determination that the connection request is not associated with the data.

13. The apparatus of claim 10, wherein the second processor is configured to:

receive other data indicative of the connection request via the network prior to the receiving of the connection request; and

transition a radio resource control state associated with the apparatus from a first state to a second state based at least in part on the receiving of the other data.

14. The apparatus of claim 10, wherein the connection request comprises at least one of a voice over internet protocol, a video telephony, instant messaging, and a push mail.

15. The apparatus of claim 10, wherein the second processor is configured to:

transmit other data indicative of a release of the connection request via the network to an electronic device external to the apparatus.

16. The apparatus of claim 10, wherein the second processor is configured to:

transmit other data indicative of a release of a radio channel to the network.

17. The apparatus of claim 10, wherein the second processor is configured to:

determine that the connection request is associated with the data set as unallowable based at least in part on a port number or an internet protocol address to which the data is directed.

18. The apparatus of claim 10, wherein the second processor is configured to:

discard the connection request as at least part of the refraining.

19. The apparatus of claim 10, wherein the connection request is transmitted to the mobile network from another electronic device external to the electronic device.

20. A non-transitory machine-readable storage device storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

receiving, at an electronic device including a first processor and a second processor, using the first processor, a connection request via a network; and

refraining from transmitting the connection request from the first processor to the second processor based at least in part on a determination that the second processor is in a sleep state, and that the connection request is associated with data set as unallowable by the second processor.
