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: Methods, systems and devices are provided for presenting event feedback information regarding participants to an event. A first radio of a first participant device carried by a first participant receives a first checkpoint communication from a checkpoint device at a first checkpoint located along a first course of the event. The first checkpoint communication includes a first checkpoint identifier and a first event time reflecting when the first participant crossed the first checkpoint. A first checkpoint event time is determined based upon the first checkpoint identifier and the first event time. Also, the first checkpoint event time is displayed on the first participant device. Further, a checkpoint device and an event server may be used to in presenting the event feedback information.

Abstract: An embodiment is directed to switching between server-arbitrated group communication sessions at an access terminal (AT) within a wireless communications system. The AT participates in a first group communication session when it receives an announce message announcing a second group communication session, acquires priority levels for the first and/or second group communication sessions and determines whether to switch between sessions based on the priority level(s). In another embodiment, the AT participates in a given processing task (e.g., a gaming session, a voice call, a group session, etc.) when it receives an alert that relates to a group communication session. If the alert is specially configured to force the given access terminal to drop the given processing task, the AT drops the given processing task irrespective of whether the AT later joins the announced group communication session.

Abstract: A call request message is sent from an access terminal to an application server in order to request initiation of a group communication session to a communication group and to request that an allocation of the floor to the given access terminal for the duration of the given group communication session remain uninterrupted by call targets of the session. The application server announces the session, and sends a floor-grant to the access terminal after the session is accepted by at least one target. The access terminal forwards media to the application server which is then forwarded to the at least one target. The floor is not transferred away from the access terminal during the session. For example, floor requests are suppressed at the at least one target, or floor requests are sent by the at least one target but are then ignored or denied by the application server.

Abstract: In an embodiment, a network communication entity obtains a location associated with an access terminal that is attempting to participate in a communication service, determines whether the obtained location satisfies a relationship with a defined location region, the defined location region establishing a first level of service restriction for the communication service within the defined location region and establishing at least a second level of service restriction for the communication service outside of the defined location region, and restricts the access terminal in accordance with the first or second level of service restriction for the communication service based on the determination. The network communication entity may correspond to the access terminal, an access network or an application server. If the access terminal detects a current, imminent or future service restriction, the given access terminal can initiate handoff to another service mechanism and/or inform the user of the service restriction.

Abstract: In an embodiment, a user equipment (UE) determines that a current serving network is associated with a network support zone of a given type, wherein network support zones of different types are characterized by different levels of support for a multimedia client application configured to manage server-arbitrated communication sessions at the UE. The UE loads zone-specific network procedures for supporting the multimedia client application within the network support zone of the given type, and then executes the zone-specific network procedures at the UE. In another embodiment, an application server determines that the current serving network of the UE is associated with the network support zone of the given type. The application server selects zone-specific network parameters and/or features based on the determination, and then interacts with the multimedia client application within the network support zone of the given type with the selected zone-specific network parameters and/or features.

Abstract: In an embodiment, an access network (AN) receives a request to allocate a given data channel (e.g., a traffic channel (TCH), Quality-of-Service, an Internet Protocol (IP) address, etc.) to a given wireless communication device (e.g., a call originator, a call target, etc.). The AN determines whether the given data channel is available for allocation to the wireless communication device. If the AN determines the given data channel not to be available for allocation to the wireless communication device, the AN determines a priority score to be associated with the received request. The AN initiates one of a plurality of data channel acquisition procedures (e.g., a preemption procedure, a queuing procedure, etc.) if the determined priority score is above at least one priority score threshold, each of the plurality of data channel acquisition procedures configured to obtain the given data channel in order to service the received request.

Abstract: In an embodiment, a call originator sends, to an application server, a request to initiate a given communication session with at least one call target, the received request configured to indicate to the application server that the given communication session is associated with a high-priority. The application server configures a call announcement to force the at least one call target to accept the given communication session, and transmits the configured call announcement to the at least one call target. The at least one call target receives the call announcement, and determines that the call announcement is configured to force the given access terminal to accept the given communication session. Responsive to the determination, the at least one call target transmits an acknowledgment to the call announcement that indicates that the at least one call target has accepted the given communication 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.
