Abstract: A user equipment (UE) participates in a coordinate-sharing communication session with at least one other UE that is arbitrated by a server (e.g., another UE participating in the session or an independent server). The UE displays a given visual representation of media content associated with the coordinate-sharing communication session. In an embodiment, the UE receives user input that indicates a selection of at least one coordinate of the given visual representation, and reports the coordinate selection(s) to the server via a coordinate packet. During the coordinate-sharing communication session, the server monitors for coordinate packets from the participating UEs and formats coordinate output frames indicative of selected coordinates at the respective UEs. In another embodiment, the UE receives a coordinate output frame indicative of coordinate selection(s) at the at least one other UE and selectively updates its given visual representation accordingly.

Abstract: The disclosure relates to decentralized presence management within a communications system performed at a user device. An embodiment of the disclosure comprises selectively updating at least one frequency at which the user device transmits presence update messages to one or more other user devices that belong to a contact group associated with the user device. The embodiment further comprises transmitting one or more presence update messages in accordance with the selectively updated frequency. Another embodiment of the disclosure comprises obtaining a subset of contacts of a subscriber operating the user device that form a presence update group. The embodiment further comprises identifying a plurality of sub-groups within the presence update group based on priorities of the subset of contacts. The embodiment further comprises transmitting one or more presence update messages to less than all of the identified plurality of sub-groups.

Abstract: In an embodiment, a user equipment (UE) participating in a server-mediated communication session maintains an identifier of the session and a list of UEs that are currently participating in the session. The UE determines to suppress its participation level in the session, and configures a member update message to include the identifier and to indicate the suppressed participation level of the UE. The UE transmits the configured member update message to each other UE currently participating in the session. In another embodiment, the UE receives a request to modify one or more of a given set of control parameters associated with the session. The UE determines whether the UE belongs to a subset of UEs that are currently participating in the session and to which permission to modify the given set of parameters is restricted. The UE selectively grants the received request based on the determination.

Abstract: In an embodiment, during a group communication session, media is received from a first set of access terminals that belong to a communication group, wherein the received media corresponds to content for presentation to a second set of access terminals that belong to the communication group. In an example, the media can be received either at an application server arbitrating the group communication session, or alternatively at a target access terminal for the received media that belongs to the second set of access terminals. Location information associated with an access terminal among the first or second sets of access terminals is determined, and the received media is selectively reformatted based on the determined location information.

Abstract: Aspects are directed to managing event distribution to applications within a wireless communications device. A first application of a plurality of applications installed on a platform of the wireless communications device is provisioned with a private address of an interface portion of a second application from among the plurality of applications. A registration message is received at the interface portion of the second application from the first application, the registration message requesting registration for event message distribution at the interface portion of the second application based on the provisioned private address. An event notifier portion of the second application registers the first application to receive event message distribution.

Abstract: Exemplary techniques for sending data packages, such as media objects, during group communication sessions between wireless telecommunication devices, such as push-to-talk communication sessions, are disclosed. In one embodiment, the data packages, such as discrete data packages, are queued at the transmitting wireless communication device and then sent to other group members upon establishment of channels for group communications to the group members. The data packages can also be queued at the group communication server prior to being sent to a target device.

Abstract: In an embodiment, an access terminal (AT) obtains media intended for transmission to a communication group during a group communication session (GCS). The communication group includes a first set of ATs configured to exchange media via a primary communication protocol (PCP) mediated by an application server (AS) and a second set of ATs configured to exchanged media via a secondary communication protocol (SCP). The AT selectively transmits the obtained media in accordance with the PCP and/or the SCP to facilitate both the first and second sets of ATs to receive the media. In an embodiment, the AS sends instructions to a given AT among the first set associated with whether the given AT is responsible for extending support of the GCS to at least one of a second set of ATs via the SCP. In another embodiment, the AS itself selectively transmits media to the communication group via the SCP.

Abstract: Systems, apparatuses and methods of determining whether to permit a call to an access terminal are disclosed. A second party is determined to be available for a communication session between a first party and the second party. Location information associated with a call permissions rule set is obtained, where the call permissions rule set includes at least one rule related to whether a communication session between the first and second parties is permissible. Further, at least one rule includes one or more location-based rules. Location information is obtained that is associated with the second party. Then, it is determined whether to permit the communication session based on the obtained location information associated with the call permissions rule set and the obtained location information associated with the second party.

Abstract: Embodiments of the present invention are directed to determining whether to switch between group calls based on priority within a wireless communications system. In an embodiment, an announce message is received at a given access terminal that announces a second group session when the given access terminal is participating in the first group session. The given access terminal acquires one or more priority levels associated with one or more of the first and second group sessions. The access terminal determines whether to switch from the first group session to the second group session based on the one or more priority levels. The access terminal selectively switches from the first group session to the second group session based on the determination.

Abstract: Systems and methods for optimizing paging cycles in a wireless communication system are disclosed. An access terminal can include logic configured to determine an optimal paging cycle and logic configured to set the paging cycle based on the optimal paging cycle, where the paging cycle varies based on at least one optimizing metric.

Abstract: Systems and methods are provided for setting up a push-to-talk group call in a wireless communications system 100. The call setup information in a call message 400 is established as potential targets 108-114 are identified on a wireless device 106 to reduce call setup time and overall system latency.

Abstract: A system and method for resolving conflicts in voice data packets received by a wireless device. Each data packet includes a source identification number, a sequence number, and an end-marker bit. The wireless device reconstructs audio streams based upon the sequence of the data packets received. If a data packet has the same source identification number as the last-received data packet and the sequence number of the data packet differs from the sequence number of the last-received data packet for more than a predefined threshold number, the wireless device ends a current audio stream and starts a new audio stream using the data from the data packet.

Abstract: In a wireless communication system such as a CDMA system, a traffic channel supporting two applications running in socket mode on a mobile station is allowed to go dormant and is released when respective idle periods associated with each socket expire, i.e., when there is no transmission over the traffic channel for the longer of two potentially unequal idle periods.

Abstract: A method and apparatus for suppressing silence frames in a stream of media includes receiving a stream of media from a user and suppressing at least one silence frame from the received stream of media. The suppressed silence frame includes an initial silence frame situated before a first media frame and/or a silence frame situated between two successive media frames.
