Abstract

Power and resource efficiency of a mobile network device are increased. In one aspect, a tail optimization protocol (TOP) enables cooperation between a mobile device and an associated radio access network to eliminate idle periods (e.g., tails) when possible. Various systems and methods described herein can leverage the ability of applications and/or their associated connections to accurately predict a long tail time, from which a mobile device can notify an associated cellular network on such an imminent tail in order to allow the cellular network to immediately release tail resources. Various other aspects provided herein realize TOP via fast dormancy and/or other similar notification mechanisms, which enable a handset or other device to notify a cellular network for immediate resource release.

Claims

1. A system, comprising:

a processor; and

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

receiving, from a network device, trace data representing an empirical network trace; and

based on the trace data, adjusting parameter data associated with a tail timing criterion that is employable to transition a user equipment from a first communicative state to a second communicative state, wherein first radio resources of a group of radio resources utilized by the user equipment in the first communicative state are greater than second radio resources of the group of radio resources utilized by the user equipment in the second communicative state.

2. The system of claim 1, wherein the operations further comprise:

determining connection data representing network connections associated with applications of the user equipment, and wherein the adjusting further comprises adjusting the parameter data based on the connection data.

3. The system of claim 1, wherein the operations further comprise:

receiving, from a content provider device, connection data representing network connections associated with the user equipment, and wherein the adjusting further comprises adjusting the parameter data based on the connection data.

4. The system of claim 3, wherein the content provider device is related to a website and the connection data is embedded within a header of the website.

5. The system of claim 1, wherein the adjusting comprises adjusting the parameter data independent of network-defined tail timing data.

6. The system of claim 1, wherein the operations further comprise:

determining timestamp data indicative of a first time at which user data transfer between the user equipment and the network device has been completed; and

based on the timestamp data, determining an inter-transfer time interval that is employed to facilitate the adjusting.

7. The system of claim 6, wherein the user data transfer is first user data transfer,

wherein the operations further comprise:

determining a second time at which second user data transfer between the user equipment and the network device is likely to be initiated, and

wherein the inter-transfer time interval is measured from the first time to the second time.

8. The system of claim 6, wherein the adjusting comprises adjusting the parameter data in response to determining that the inter-transfer time interval is greater than a tail threshold interval.

9. The system of claim 6, wherein the determining the inter-transfer time interval comprises:

receiving information representing the inter-transfer time interval from an application of the user equipment.

10. The system of claim 9, wherein the application is a first application, and wherein the user data transfer is associated with a second application of the user equipment.

11. A method, comprising:

receiving, by a system comprising a processor, trace data representing an empirical network trace, wherein the receiving comprises receiving the trace data from a network device; and

based on the trace data, modifying, by the system, parameter data associated with a tail timing criterion that is to be utilized to transition a user equipment from a first communicative state to a second communicative state, wherein a first group of radio resources utilized by the user equipment in the first communicative state is greater than a second group of the radio resources utilized by the user equipment in the second communicative state.

12. The method of claim 11, wherein the modifying further comprises modifying the parameter data based on connection data representing network connections between the user equipment and the network device.

13. The method of claim 12, further comprising:

receiving, by the system, the connection data from a content provider device.

14. The method of claim 12, further comprising:

receiving, by the system, the connection data from an application of the user equipment.

determining, by the system, the connection data based on header data of a webpage accessed by an application of the user equipment.

16. A machine-readable storage medium comprising executable instructions that, in response to execution cause a system comprising a processor to perform operations, comprising:

receiving, from a network device, trace data representing an empirical network trace; and

based on the trace data, customizing a tail timing criterion that is to be utilized to transition a user equipment from a first communicative state to a second communicative state, wherein first radio resources utilized by the user equipment in the first communicative state are greater than second radio resources utilized by the user equipment in the second communicative state.

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

determining connection data representing network connections between the user equipment and the network device, and wherein the customizing is based on the connection data.

18. The machine-readable storage medium of claim 17, wherein the determining the connection data comprises receiving the connection data from a content provider device.
