Abstract

Dynamic power class re-registration of wireless devices is provided. A wireless device can exchange data with a communications network. While exchanging data, the device can monitor its usage and based on the usage, generate a power change request. The device can then send the power change request to the communications network, prior to or in conjunction with powering down the device. In this regard, the communications network can receive the power change request, generate instructions for the wireless device, and adjust network resources based on the power change request. The instructions can then be sent to the wireless device. Since the device re-registers its power class with the communications network, handoffs, internetwork thresholds, network resources and other network parameters can be adjusted to compensate for the changed power class resulting into improved service for a user of the wireless device.

Claims

1. A method, comprising:

in response to determining, by a mobile device comprising a processor, that an absorption rate associated with the mobile device satisfies a defined condition with respect to a radio frequency energy emitted by the mobile device, sending, by the mobile device, power class registration data directed to a network device during a data gap that has been determined to be present in data being exchanged between the network device and the mobile device, wherein the power class registration data comprises a request for adjustment of a power of the mobile device; and

in response to determining, by the mobile device, that an instruction for the adjustment of the power was not received during a defined period of time, sending, by the mobile device, a message directed to the network device for registration of a change of the power of the mobile device, and initiating, by the mobile device, a power down of the mobile device.

2. The method of claim 1, further comprising:

in response to determining that the data gap is present in the data being exchanged between the network device and the mobile device, resetting, by the mobile device, a timer.

3. The method of claim 2, wherein the sending the power class registration data comprises sending the power class registration data directed to the network device based on a time represented by the timer.

4. The method of claim 1, wherein the determining that the absorption rate satisfies the defined condition comprises determining, using a proximity sensor, a proximity of the mobile device to a body of a user of the mobile device.

5. The method of claim 4, further comprising:

disabling, by the mobile device, the determining of the proximity based on an input received via an interface of the mobile device.

6. The method of claim 1, further comprising:

in response to the sending of the power class registration data, receiving, by the mobile device, the instruction for the adjustment of the power of the mobile device.

7. An apparatus, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

in response to determining that an absorption rate associated with the apparatus satisfies a defined condition with respect to radio frequency energy emitted by the apparatus, generating power class registration data with respect to a change of a power class registration of the apparatus;

sending the power class registration data to a network device during a period of a data gap that has been identified to be present in data being exchanged between the network device and the apparatus; and

in response to determining that an incoming message directing the apparatus to modify a power level of the apparatus has not been received during a defined period of time, sending an outgoing message directed to the network device with respect to registration of the power level of the apparatus, and initiating a power down of the apparatus.

8. The apparatus of claim 7, wherein the power class registration data comprises information representing a target power level for the apparatus.

9. The apparatus of claim 7, wherein the generating the power class registration data comprises generating a request to adjust control power for the apparatus.

10. The apparatus of claim 9, wherein the operations further comprise:

based on the request, waiting for the defined period of time to receive an instruction from the network device.

11. The apparatus of claim 7, wherein the operations further comprise:

in response to determining that the data gap is present in the data being exchanged between the network device and the apparatus, resetting a power class registration timer.

12. The apparatus of claim 11, wherein the sending the power class registration data comprises sending the power class registration data to the network device based on a time represented by the power class registration timer.

13. The apparatus of claim 7, wherein the operations further comprise:

creating the power class registration data based on an input received via an interface of the apparatus.

14. The apparatus of claim 7, wherein the operations further comprise:

in response to the sending of the power class registration data, receiving, from the network device, a direction to adjust the power level of the apparatus.

15. A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

in response to determining that an absorption rate of a mobile device satisfies a defined condition with respect to a radio frequency energy emitted by the mobile device, sending power class registration data directed to a network device during a data gap determined to be present in data being exchanged between the network device and the mobile device, wherein the power class registration data comprises a request for adjustment of a power being consumed by the mobile device; and

in response to determining that an instruction for the adjustment of the power being consumed by the mobile device has not been received by the mobile device during a defined period of time, sending a power level registration request directed to the network device and powering down the mobile device.

16. The non-transitory machine-readable storage medium of claim 15, wherein the operations further comprise:

generating, based on the power class registration data, a network instruction corresponding to a network resource.

17. The non-transitory machine-readable storage medium of claim 16, wherein the operations further comprise:

initiating adjustment of the network resource based on the network instruction.
