Session management and notification mechanisms for push-to-talk (PTT)
An embodiment method includes receiving, by a notification service running on a processor, a notification from a first component of a push-to-talk (PTT) platform. The notification is for transmission to a PTT client. The method further includes determining, by the notification service, an access transport type used by the PTT client to communicate with the PTT platform, and selecting, by the notification service, a second component to transmit the notification to the PTT client. Selecting the second component is in accordance with the access transport type used by the PTT client. The method further includes transmitting, by the notification service, the notification to the second component.
1. A method comprising:
receiving, by a processor of a first deployment site of a push-to-talk (PTT) platform, from a PTT client protected by a firewall that does not permit unsolicited network traffic, a registration request to establish a primary notification channel;
establishing, by the processor of the first deployment site, the primary notification channel for the purpose of signaling between the PTT client and the PTT platform;
receiving, by a processor of a second deployment site of the PTT platform, from the PTT client protected by the firewall that does not permit unsolicited network traffic, a registration request to establish a secondary notification channel;
establishing, by the processor of the second deployment site, the secondary notification channel, wherein the secondary communication channel utilizes a UDP transport protocol;
determining, by the PTT platform, that the primary notification channel has failed;
providing an indication of the failure of the primary notification channel to the PTT client over the secondary notification channel; and
re-establishing the primary notification channel, wherein the re-establishment of the primary notification channel is initiated by the PTT client protected by the firewall that does not permit unsolicited network traffic.
2. The method of claim 1 , wherein the first processor and the second processor are physically different processors.
3. The method of claim 1 , wherein the first deployment site and the second deployment site are geographically diverse.
4. The method of claim 1 wherein the secondary notification channel is established using a protocol selected from the group of protocols consisting of Session Initiation Protocol (SIP), Message Queueing Telemetry Transport (MQTT), and Websocket.
5. The method of claim 1 wherein the secondary notification channel is an open Operating System (OS) notification channel.
6. The method of claim 5 wherein the open OS notification channel is selected from the group of open OS notification channels consisting of Apple Notification Service and Google Notification Service.
7. A system comprising:
a first processor;
a second processor; and
a non-transitory processor readable medium storing a set of instructions thereon on that when executed by the first and second processors cause the processor to:
receive, by the first processor at a first deployment site of a push-to-talk (PTT) platform, from a PTT client protected by a firewall that does not permit unsolicited network traffic, a registration request to establish a primary notification channel;
establish, by the first processor of the first deployment site, the primary notification channel for the purpose of signaling between the PTT client and the PTT platform;
receive, by a second processor at a second deployment site of the PTT platform, from the PTT client protected by the firewall that does not permit unsolicited network traffic, a registration request to establish a secondary notification channel;
establish, by the second processor of the second deployment site, the secondary notification channel, wherein the secondary communication channel utilizes a UDP transport protocol;
determine, by the PTT platform, that the primary notification channel has failed;
provide an indication of the failure of the primary notification channel to the PTT client over the secondary notification channel; and
re-establish the primary notification channel, wherein the re-establishment of the primary notification channel is initiated by the PTT client protected by the firewall that does not permit unsolicited network traffic.
8. The system of claim 7 , wherein the first processor and the second processor are physically different processors.
9. The system of claim 7 , wherein the first deployment site and the second deployment site are geographically diverse.
10. The system of claim 7 wherein the secondary notification channel is established using a protocol selected from the group of protocols consisting of Session Initiation Protocol (SIP), Message Queueing Telemetry Transport (MQTT), and Websocket.
11. The system of claim 7 wherein the secondary notification channel is an open Operating System (OS) notification channel.
12. The system of claim 11 wherein the open OS notification channel is selected from the group of open OS notification channels consisting of Apple Notification Service and Google Notification Service.
13. A non-transitory processor readable medium storing a set of instructions thereon on that when executed by a processor at a deployment site cause the processor to:
receive, by a processor at a first deployment site of a push-to-talk (PTT) platform, from a PTT client protected by a firewall that does not permit unsolicited network traffic, a registration request to establish a primary notification channel;
establish, by the processor of the first deployment site, the primary notification channel for the purpose of signaling between the PTT client and the PTT platform;
receive, by a processor at a second deployment site of the PTT platform, from the PTT client protected by the firewall that does not permit unsolicited network traffic, a registration request to establish a secondary notification channel; and
establish, by the processor of the second deployment site, the secondary notification channel, wherein the secondary communication channel utilizes a UDP transport protocol;
determine, by the PTT platform, that the primary notification channel has failed;
provide an indication of the failure of the primary notification channel to the PTT client over the secondary notification channel; and
re-establish the primary notification channel, wherein the re-establishment of the primary notification channel is initiated by the PTT client protected by the firewall that does not permit unsolicited network traffic.
14. The medium of claim 13 , wherein the first processor and the second processor are physically different processors.
15. The medium of claim 13 , wherein the first deployment site and the second deployment site are geographically diverse.
16. The medium of claim 13 wherein the secondary notification channel is established using a protocol selected from the group of protocols consisting of Session Initiation Protocol (SIP), Message Queueing Telemetry Transport (MATT), and Websocket.
17. The medium of claim 13 wherein the secondary notification channel is an open Operating System (OS) notification channel.
18. The medium of claim 17 wherein the open OS notification channel is selected from the group of open OS notification channels consisting of Apple Notification Service and Google Notification Service.
