Patent number: 10085124Abstract: A system and method to leverage Web Real-Time Communication (WebRTC) for implementing Push-to-Talk (PTT) solutions. One or more servers interface to a communications network to perform advanced voice services for one or more wireless or wired user devices, wherein the advanced voice services include a two-way half-duplex voice call within a group of the user devices comprising a PTT call session. At least one of the user devices communicates with at least one of the servers during the PTT call session using a WebRTC connection, and at least the media streams for the PTT call session are transmitted between the server and the user device using the WebRTC connection.Type: GrantFiled: April 28, 2017Date of Patent: September 25, 2018Assignee: KODIAK NETWORKS INC.Inventors: Krishnakant M.

Patent number: 9961514Abstract: A system and method for providing effective presence for Push-to-talk-over-Cellular (PoC) networks, wherein one or more servers performs an effective presence delivery method that reduces presence notifications delivered to mobile units participating in advanced voice services, while ensuring that the presence notifications relevant to the mobile units are available when the advanced voice services are invoked by the mobile units. The presence notifications are used to indicate a change in network presence of the mobile units. In addition, the presence notifications are used to indicate a change in self-availability status of the mobile units.Type: GrantFiled: January 22, 2016Date of Patent: May 1, 2018Assignee: KODIAK NETWORKS, INC.Inventors: Gorachand Kundu, Giridhar K.

Patent number: 9913300Abstract: A Push-to-Talk-over Cellular (PoC) implementation for use in a wireless communications network, wherein one or more servers interface to the wireless communications network to perform the PoC call sessions. Both the servers and the mobile units that use the PoC call sessions communicate with each other using SIP/IP (Session Initiation Protocol/Internet Protocol) control messages within the wireless communications network, and one or more of the servers switches RTP/IP (Realtime Transport Protocol/Internet Protocol), RTCP/IP (Realtime Transport Control Protocol/Internet Protocol), or MBCP/IP (Media Burst Control Protocol/Internet Protocol) voice packets for the PoC call sessions between the mobile units across the wireless communications network.Type: GrantFiled: December 11, 2012Date of Patent: March 6, 2018Assignee: Kodiak Networks, Inc.Inventors: Ravi Ayyasamy, Gorachand Kundu, Krishnakant M.

Patent number: 9883357Abstract: A system and method for providing radio access network (RAN) aware service delivery for Push-to-talk-over-Cellular (PoC) networks, wherein at least one of the servers performs an presence delivery method that reduces presence notifications delivered to the mobile units participating in communications services. The effective presence delivery method may comprise: throttling the delivery of the presence notifications; avoiding simultaneous dispatch of the presence notifications to multiple watchers located in the same cell or group of cells of the wireless communications network; or the server delaying sending the presence notifications for a mobile unit until the mobile unit triggers the server.Type: GrantFiled: July 8, 2016Date of Patent: January 30, 2018Assignee: KODIAK NETWORKS, INC.Inventors: Gorachand Kundu, Brahmananda R.

Patent number: 9137646Abstract: A system and method for providing advanced voice services in a wireless communications network. The system includes at least one server that exchanges messages with mobile units, in order to indicate that a user is neither online or offline, but is temporarily unreachable or unavailable. The user may be temporarily unreachable or unavailable due to connectivity issues with the user's mobile unit in the wireless communications network. Presence information for the user is distributed from the server to watchers, wherein the presence information indicates that the user is offline when the user is temporarily unreachable or unavailable. Various techniques may be implemented to determine how long the user's mobile unit must remain connected to the wireless communications network, before the presence information indicates that the user is online.Type: GrantFiled: November 29, 2013Date of Patent: September 15, 2015Assignee: Kodiak Networks, Inc.Inventors: Gorachand Kundu, Krishnakant M.

Patent number: 8958348Abstract: A Hybrid Push-to-Talk (PTT) function for use in wireless communications networks, such as cellular mobile telephone networks. The cellular mobile telephone network includes a Real-Time Exchange (RTX) that interfaces to at least one Mobile Switching Center (MSC) in the cellular mobile telephone network to provide instant two-way half-duplex voice messaging within a group of users. In the Hybrid PTT function, first or initial talkbursts or volleys are transmitted by the RTX from an originating mobile to terminating mobiles on pre-established Internet Protocol (IP) sessions between the RTX and the mobiles. In addition, circuit channels are established by the RTX with the mobiles through the MSC in parallel with the first talkburst or volley. Thereafter, second or subsequent talkbursts or volleys are transmitted by the RTX from the originating mobile to the terminating mobiles on the circuit channels.Type: GrantFiled: October 20, 2009Date of Patent: February 17, 2015Assignee: Kodiak Networks, Inc.Inventors: Krishnakant M.

Patent number: 8478261Abstract: A predictive wakeup function for Push-to-Talk-over Cellular (PoC) call setup optimizations in a cellular mobile phone network. In performing the predictive wakeup for call setup optimizations, an originating mobile transmits an event trigger to a real-time exchange that interfaces to a mobile switching center in the cellular mobile phone network. The real-time exchange transmits a wakeup message to one or more terminating mobiles of predicted participants, in order to transition the terminating mobiles of the predicted participants from a dormant state to an active state prior to a call being setup with the terminating mobiles of the predicted participants. The terminating mobiles of the predicted participants are identified by a predictive wakeup mechanism before the originating mobile sends a list of one or more terminating mobiles of actual participants to the real-time exchange.Type: GrantFiled: April 25, 2011Date of Patent: July 2, 2013Assignee: Kodiak Networks, Inc.Inventors: Brahmananda R. Vempati, Krishnakant M. Patel, Pratap Chandana, Anand Narayanan, Ravi Ayyasamy, Bruce D. Lawler, Basem A. Ardeh, Ramu Kandula, Gorachand Kundu, Ravi Shankar Kumar, Bibhudatta Biswal
