Server-Side Buffering Of Push-To-Talk Messages
A push-to-talk server receives a request from a client device to initiate a push-to-talk communication with one or more recipient devices. The push-to-talk server receives, from the client device, an audio recording recorded during a latency period between initiation of the push-to-talk communication at the client device and receipt of the request by the push-to-talk server. The push-to-talk server transmits the audio recording to the one or more recipient devices. The push-to-talk server receives real-time audio from the client device. The push-to-talk server buffers the real-time audio for transmission to the one or more recipient devices after completion of playback of the audio recording.
1 . A method, comprising:
receiving, by a push-to-talk server, a request from a client device to initiate a push-to-talk communication with one or more recipient devices;
receiving, from the client device, an audio recording recorded during a latency period between initiation of the push-to-talk communication at the client device and receipt of the request by the push-to-talk server;
transmitting, by the push-to-talk server, the audio recording to the one or more recipient devices;
receiving, by the push-to-talk server, real-time audio from the client device; and
buffering, by the push-to-talk server, the real-time audio for transmission to the one or more recipient devices after completion of playback of the audio recording.
2 . The method of claim 1 , wherein the audio recording comprises an audio file or raw audio data.
3 . The method of claim 1 , further comprising:
transmitting the real-time audio for playback at the one or more recipient devices with a delay based on a duration of the audio recording.
4 . The method of claim 1 , further comprising:
after passage of a delay period that is based on a time length of the audio recording since transmission of the audio recording, transmitting the real-time audio for playback at the one or more recipient devices.
5 . The method of claim 1 , further comprising:
transmitting, to the client device, a confirmation that a push-to-talk channel is locked for use by the client device.
6 . The method of claim 1 , further comprising:
transmitting, to the client device, a signal that a push-to-talk channel is currently unavailable, and that the push-to-talk server is buffering the real-time audio for future transmission.
7 . The method of claim 1 , further comprising:
identifying the one or more recipient devices based on stored information associated with the client device.
8 . A non-transitory computer readable medium storing instructions operable to cause one or more processors to perform operations comprising:
receiving, by a push-to-talk server, a request from a client device to initiate a push-to-talk communication with one or more recipient devices;
receiving, from the client device, an audio recording recorded during a latency period between initiation of the push-to-talk communication at the client device and receipt of the request by the push-to-talk server;
transmitting, by the push-to-talk server, the audio recording to the one or more recipient devices;
receiving, by the push-to-talk server, real-time audio from the client device; and
buffering, by the push-to-talk server, the real-time audio for transmission to the one or more recipient devices after completion of playback of the audio recording.
9 . The non-transitory computer readable medium of claim 8 , wherein the audio recording comprises at least one audio file.
10 . The non-transitory computer readable medium of claim 8 , the operations further comprising:
transmitting the real-time audio for delayed playback at the one or more recipient devices.
11 . The non-transitory computer readable medium of claim 8 , the operations further comprising:
after passage of a delay period, transmitting the real-time audio for playback at the one or more recipient devices.
12 . The non-transitory computer readable medium of claim 8 , the operations further comprising:
transmitting, to the client device, a confirmation that a push-to-talk channel is available for use by the client device.
13 . The non-transitory computer readable medium of claim 8 , the operations further comprising:
transmitting, to the client device, a signal that a push-to-talk channel is currently unavailable, and that the push-to-talk server is storing the real-time audio for future transmission.
14 . The non-transitory computer readable medium of claim 8 , the operations further comprising:
identifying the one or more recipient devices based on a push-to-talk group of the client device.
15 . A system, comprising:
a memory subsystem storing instructions; and
processing circuitry configured to execute the instructions to:
receiving, by a push-to-talk server, a request from a client device to initiate a push-to-talk communication with one or more recipient devices;
receiving, from the client device, an audio recording recorded during a latency period between initiation of the push-to-talk communication at the client device and receipt of the request by the push-to-talk server;
transmitting, by the push-to-talk server, the audio recording to the one or more recipient devices;
receiving, by the push-to-talk server, real-time audio from the client device; and
buffering, by the push-to-talk server, the real-time audio for transmission to the one or more recipient devices after completion of playback of the audio recording.
16 . The system of claim 15 , wherein the audio recording is stored in an audio file or raw audio data.
17 . The system of claim 15 , the processing circuitry further configured to execute the instructions to:
transmit the real-time audio for playback at the one or more recipient devices with a latency based on a duration of the audio recording.
18 . The system of claim 15 , the processing circuitry further configured to execute the instructions to:
after passage of a time period corresponding to a time length of the audio recording since transmission of the audio recording, transmit the real-time audio for playback at the one or more recipient devices.
19 . The system of claim 15 , the processing circuitry further configured to execute the instructions to:
transmit a confirmation that a push-to-talk channel is being used to transmit the audio recording and the real-time audio from client device.
20 . The system of claim 15 , the processing circuitry further configured to execute the instructions to:
transmit, to the client device, a signal that a push-to-talk channel is currently unavailable, and that the real-time audio is being stored for future transmission.
