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 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.
