Abstract

A more efficient network can be achieved by leveraging an adaptive dejitter buffer. The dejitter buffer can be dynamically adjusted based off a network data analysis. A communication handover can be adjusted or shifted based on voice inactivity data related to a forecasted punctuation. The dejitter buffer memory/depth of a mobile device can also be adjusted in accordance with receiving a delay interruption length associated with another mobile device. Thereafter, the dejitter buffer memory can be filled with voice packet data to decrease a packet delay variation at the mobile device.

Claims (49)

1. A method, comprising:

accessing, by a first network device comprising a processor, gap data related to a gap in voice packet data, wherein the gap is indicative of a lack of voice activity and the gap is related to a handover condition associated with a mobile device and network devices other than the first network device, wherein the handover condition is related to a handover of a signal of the mobile device from being communicated to the first network device to a second network device of the network devices;

analyzing, by the first network device, the gap data to determine a type of the handover and a punctuation type;

based on the punctuation type and the gap indicative of the lack of voice activity, deferring, by the first network device, the handover of the signal, resulting in a deferred handover of the signal;

increasing, by the first network device, a memory size of a dejitter buffer based on the gap data and the type of the handover resulting in an increased memory size of the dejitter buffer;

storing, by the first network device, the voice packet data to fill a capacity of the increased memory size of the dejitter buffer;

sending, by the first network device, data related to the handover condition being satisfied to the mobile device:,

converting, by the first network device, the voice packet data to text data, wherein the text data comprises punctuation data representative of a punctuation; and

analyzing, by the first network device, the text data to verify the punctuation type is represented in the text data.

2. The method of claim 1 , wherein the converting being performed is an indication of the voice activity having occurred.

3. The method of claim 1 , further comprising:

predicting, by the first network device, the gap in the voice packet data based on the punctuation type.

4. The method of claim 1 , wherein the type of the handover is associated with a length of an interruption of the handover.

5. The method of claim 1 , wherein the punctuation type is a question mark type.

6. The method of claim 1 , wherein the punctuation type is a comma type.

7. A system, comprising:

a processor; and

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

receiving voice packet data associated with a signal handover of a mobile device between a first network device and a second network device, wherein the voice packet data comprises data related to a voice inactivity;

analyzing the voice packet data to determine a handover interruption length, resulting in handover interruption length data representative of the handover interruption length;

analyzing the data related to the voice inactivity to determine a punctuation type;

in response to the punctuation type being determined, deferring the signal handover based on the data related to the voice inactivity, resulting in a deferred signal handover;

sending an indication to the mobile device indicating that a handover condition has been determined to have been satisfied; and

converting the punctuation type to text data, wherein the text data comprises punctuation data representative of the punctuation.

8. The system of claim 7 , wherein the punctuation type is a period.

9. The system of claim 7 , wherein the indication is a first indication, and the operations further comprise:

sending a second indication that the second network device is ready for the signal handover.

10. The system of claim 7 , wherein the operations further comprise:

receiving distance data in relation to respective distances of the mobile device to the first network device and the second network device.

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

initiating the signal handover between the first network device and the second network device.

12. The system of claim 7 , wherein the converting is performed in response to the voice inactivity having occurred.

13. The system of claim 7 , wherein a handover type comprises an inter radio access technology for sending handover detection message data representative of a handover detection message.

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

receiving voice packet data related to a handover detection message associated with a signal of a mobile device;

analyzing the voice packet data comprising determining whether the voice packet data comprises dormancy packet data related to the voice packet data;

based on a first determination, as a result of the analyzing, that the voice packet data comprises the dormancy packet data, shifting a signal handover and increasing a dejitter buffer from a first capacity to a second capacity, wherein the dejitter buffer decreases a voice packet delay variation associated with queuing the voice packet data;

based on a second determination of a punctuation type from the dormancy packet data, deferring the signal handover based on the dormancy packet data, resulting in a deferred signal handover;

storing the voice packet data in the dejitter buffer until the dejitter buffer is at the second capacity;

in response to the storing, converting the voice packet data to text data, wherein the text data comprises punctuation data representative of the punctuation type; and

sending an indication that the dejitter buffer is at the second capacity to the mobile device.

15. The non-transitory machine readable medium of claim 14 , wherein the operations further comprise:

associating punctuation data with the dormancy packet data.

16. The non-transitory machine readable medium of claim 15 , wherein the punctuation data comprises the punctuation type.

17. The non-transitory machine readable medium of claim 16 , wherein the second capacity is proportional to a time gap associated with the punctuation type.

18. The non-transitory machine readable medium of claim 16 , wherein the handover detection message is associated with the punctuation type.

19. The non-transitory machine readable medium of claim 16 , wherein the increasing the size of the dejitter buffer is proportional to a value associated with the punctuation type.

20. The non-transitory machine readable medium of claim 14 , wherein the mobile device is a first mobile device, wherein the indication is a first indication, and wherein the operations further comprise:

sending a second indication to the first mobile device that a second mobile device is ready for the signal handover.
