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

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 a 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 from the first network device to being communicated from a second network device of the network devices;

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

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

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

generating, 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, further comprising:

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

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

3. The method of claim 2, wherein the sending comprises sending the punctuation type, and wherein the punctuation type is a question mark type.

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

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

6. The method of claim 1, further comprising:

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

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

8. 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 transfer of a mobile device from being connected to a first network device to being connected to a second network device, wherein the voice packet data comprises data related to a voice inactivity, and wherein the signal transfer is to occur at a first time;

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

in response to the punctuation type being determined by the analyzing, deferring the signal transfer based on the data related to the voice inactivity, resulting in a deferred signal transfer to occur at a second time after the first time;

sending an indication to the mobile device indicating that a transfer 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.

9. The system of claim 8, wherein the operations further comprise:

analyzing the voice packet data to determine a transfer interruption length, resulting in transfer interruption length data representative of the transfer interruption length.

10. The system of claim 9, wherein a type of transfer, determined from the transfer interruption length, comprises an inter radio access technology for sending transfer detection message data representative of a transfer detection message.

11. The system of claim 8, wherein the converting is performed in response to the voice inactivity being determined to have occurred.

12. The system of claim 8, wherein the indication is a first indication, and wherein the operations further comprise:

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

13. The system of claim 8, 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.

14. The system of claim 8, wherein the operations further comprise:

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

15. A non-transitory machine-readable 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;

based on a first determination, in response to the receiving, that the voice packet data comprises dormancy packet data related to the voice packet data, 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 as compared to without the dejitter buffer;

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

in response to the deferring, 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.

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

analyzing the voice packet data, and wherein the analyzing comprises determining whether the voice packet data comprises dormancy packet data.

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

storing the voice packet data in the dejitter buffer until the dejitter buffer is determined to be at the second capacity.

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

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

associating punctuation data with the dormancy packet data, and wherein the punctuation data comprises the punctuation type.

20. The non-transitory machine-readable medium of claim 17, wherein the increasing the dejitter buffer is proportional to a value associated with the punctuation type.
