Abstract: Systems, methods, and devices of the various embodiments enable dynamically creating and joining group communication sessions without (i.e., “free of”) operator-controlled or operator-assisted provisioning. By encoding group call provisioning information in a bar code, such as a Quick Response Code (“QR code”), that participants can scan using their mobile communication devices (e.g., smart phones), a group call may be created and provisioned on communication devices. The QR code encodes the information needed to initiate and/or join a group communication session maintained by a group communication server.

Abstract: Exemplary techniques for sending data packages that can include geographic information during group communication sessions between wireless telecommunication devices, such as push-to-talk communication sessions, are disclosed. In an embodiment the data packages are wirelessly transmitted by a communication device to a group communication server and then sent to other group members.

Abstract: The various embodiments include methods implemented by a first mobile device for updating presence information for a second mobile device stored in memory of the first mobile device when the first mobile device determines that a calculated update quantification exceeds a particular threshold value. In an embodiment, the first mobile device may select one channel from a plurality of available communication channels in response to determining that the update quantification exceeds a threshold value. In a further embodiment, the first mobile device may update the presence information of the second mobile device via that selected channel.

Abstract: In an embodiment, an originating device sends a request, to a server, to initiate a full-duplex session with a target device. Responsive to the full-duplex request, a half-duplex session is set-up from the originating device to the target device before the full-duplex session is set-up. The target device indicates its acceptance of the half-duplex session, receives half-duplex media from the originating device and selectively indicates its acceptance of the full-duplex session. In another embodiment, during a session currently supported either by half-duplex or full-duplex, the server arbitrating the session receives a request from one of the session participants to transition the session to another duplex-type. The server then selectively transitions the duplex-type of the session.

Abstract: Techniques for optimizing presence information update requests for wireless devices on a wireless communication network by reducing the amount of access-network resources are provided. In an exemplary embodiment, presence information updates can be optimized by a presence module that is a single point of contact on a mobile device for presence requests from presence aware applications.

Abstract: Embodiments are directed to managing a prepaid server-arbitrated group communication session within a wireless communications system. A server receives, from a session originator, a request to setup a prepaid group communication session with at least one session target, the prepaid group communication session requiring each session participant to have an available prepaid account balance above a threshold level. The server sends a query to an online charging system to determine whether at least the session originator has a prepaid account with an available balance at least equal to the threshold level. The server initiates setup of the requested prepaid group communication session without waiting to receive a response to the query, thereby reducing latency associated with set-up of the prepaid group communication session.

Abstract: The disclosure is directed to recording voice data transmissions between mobile communication devices. An embodiment of the disclosure receives, at a first mobile communication device, an indication that a subsequent voice transmission segment may or may not be recorded by at least one other mobile communication device, and transmits, from the first mobile communication device, an indication to said at least one other mobile communication device that the subsequent voice transmission segment may or may not be recorded. Another embodiment receives an indication from at least one other mobile communication device that a subsequent voice transmission segment may or may not be recorded by said mobile communication device, and if the received indication indicates that the subsequent voice transmission segment may be recorded, records at least a portion of the subsequent voice transmission segment, and stores the recorded portion in a memory associated with said mobile communication device.

Abstract: A system, method, and computer readable product for allowing a member of a mobile communications group, such as a push-to-talk (PTT) group, to receive indications from at least one other mobile communication device that a current conversation or talk spurt may be recorded. The member may further record or receive the recorded conversation or talk spurt, and store the recorded conversation or spurt in a local memory for later retrieval or automatic playback.

Abstract: A system and method for producing real-time results of performance data for wireless communications servers are disclosed. A plurality of bins, each bin corresponding to a range, are maintained. When a measurable event is detected, the event is placed into the corresponding bin. When a performance metric is desired, it is calculated based on each bin, and the metric is returned, with an accuracy inversely proportional to the size.

Abstract: Systems, methods, and computer-readable storage media are disclosed that allow adaptive automatic detail diagnostic log collection for self-diagnosis and auto-recovery. In an embodiment, a group communication server determines that a fault has occurred with a group communication between wireless communication devices. The group communication server determines a set of events to log based on the fault, and instructs components that host the group communication to begin logging a set of events. Upon determining that logging the set of events can no longer be performed, such as due to too high of a load within a component of the group communication, the group communication server adapts the logging by logging a second set of events that will not cause too high a load, and can dynamically when resources become available.

Abstract: In an embodiment, an access terminal (AT), requests a non-exclusive floor (NEF) for a group communication session (GCS) in response to a detection that a user of the AT intends to speak to an associated communication group (CG). In another embodiment, the AT later requests that its NEF for the GCS be revoked in response to a detection that the user of the AT no longer intends to speak to the CG. In another embodiment, another AT holds a NEF for the GCS, and a user of the AT decides to revoke the other AT's NEF such that the AT sends a floor-revocation request to an application server (AS) that is arbitrating the GCS. In another embodiment, the AS grants NEFs to multiple ATs, selectively mixes media received from the ATs for transmission to the CG, and selectively revokes NEFs from one or more of the multiple ATs.

Abstract: Techniques are disclosed for reducing the time for a wireless communication device originating a group communication, such as a push-to-talk call, to receive a call failure indication on a wireless communications system. In an embodiment, a group communications server receives a request to initiate a call with a target from an originator, and sends a corresponding message to a network node. If the call cannot be completed, the server receives from the network node an internet control message protocol (ICMP) message indicative of there being no connection between the network node and the target wireless communication device. In response to the message, the group communications server sends a status failure message to the originating wireless communication device.

Abstract: In an embodiment, a first terminal detects a request to initiate a call session (e.g., a VoIP session) from the first terminal to a second terminal, stores first time information indicative of when the request to initiate the call session is detected and transmits a call invite message to the second terminal. The first terminal receives a call answer from the second terminal in response to the call invite message, and stores second time information indicative of when the call answer is received. The first terminal sends Post Dial Delay (PDD) information based on the first and second time information. A server receives the PDD information within a signaling message defined by a communication protocol associated with the call session or the information needed to determine the PDD of the call session.

Abstract: In an embodiment, a given access terminal (AT) detects a request to initiate a Push-to-Talk (PTT) session, and stores first time information indicative of when the request to initiate the PTT session is detected. The given AT sends the request as a message to an access network, which forwards an announce message to announce the PTT session to a plurality of access terminals. At least one of the plurality ATs accepts the announce message to join the PTT session, and the access network sends a message to the given AT granting permission to begin the PTT session. The given AT stores second time information indicative of when the permission is received, and sends PTT latency information based on the first and second time information to the access network, the PTT latency information related to an initial PTT latency of the PTT session.

Abstract: In an embodiment, an originating device sends a request, to a server, to initiate a full-duplex session with a target device. Responsive to the full-duplex request, a half-duplex session is set-up from the originating device to the target device before the full-duplex session is set-up. The target device indicates its acceptance of the half-duplex session, receives half-duplex media from the originating device and selectively indicates its acceptance of the full-duplex session. In another embodiment, during a session currently supported either by half-duplex or full-duplex, the server arbitrating the session receives a request from one of the session participants to transition the session to another duplex-type. The server then selectively transitions the duplex-type of the session.
