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: A wireless telecommunication device and method of generating a domain ID from the wireless telecommunications network identifier of other communicating devices, such as a telephone number or mobile identification number (MIN), and creating a SIP URL to direct communications across a TCP/IP capable network. The wireless telecommunication device can generate more than one domain ID for same network identifier, and can include geographic information in the domain name to provide additional information about the other communicating device within the SIP URL address.

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: Embodiments are directed to a network-connection report is received at a server (e.g., a presence server) from a first user equipment (UE) that identifies a type of physical-layer network to which the first UE is connected. In response to a determination that the first UE is engaged in a communication session with a second UE, the server sends a notification message to the second UE that indicates the type of physical-layer network to which the first UE is connected. The second UE receives the notification message and determines a target physical-layer network for supporting the second UE's participation in the communication session based at least in part on the type of physical-layer network to which the first UE is connected. The second UE selectively transitions to the target network based on the determination.

Abstract: Methods, systems and devices are provided for restoring a multiple call session. A communication terminal can restore a multiple call session after a fault. A network interface can couple the terminal to a network including multiple access terminals associated with the multiple call session. A request for a state of the multiple call session can be transmitted and received by a server in the network. A response including the state can be received. The multiple call session can be restored based on the state of the multiple call session and other information.

Abstract: In an embodiment, an access terminal sends a multicast session registration request to an access network. The access network determines whether to assign a unicast traffic channel (e.g., media access control (MAC) identifier (ID)) to the access terminal, for the access terminal to provide feedback (e.g., channel quality indicators (CQIs) associated with the multicast session, based on a number of access terminals that have been assigned unicast traffic channels for the multicast session and/or for applications other than the multicast session. The access network configures a traffic channel assignment message to include an identifier for the multicast session, and to further include an assignment of the unicast traffic channel if the determining step determines to assign the unicast traffic channel to the access terminal. The access network sends the traffic channel assignment message to the access terminal including at least the multicast session identifier.

Abstract: An OCDMA transmission arrangement involves encoding both first and second nominally orthogonal polarization signals with a same long code, and transmitting the long-encoded first and second nominally orthogonal polarization signals from respective first and second transmission sources to at least one destination. A corresponding OCDMA demodulating arrangement demodulates the first and second nominally orthogonal polarization signals that were transmitted from respective first and second transmission sources after having been encoded with the same long code. The demodulation arrangement involves receiving the encoded first and second nominally orthogonal polarization signals, and applying the same long code to the received encoded first and second nominally orthogonal polarization signals.

Abstract: In an embodiment, an access terminal sends a request for a level of Quality of Service (QoS) resources to an access network, the QoS resource request associated with a call attempt by the access terminal. The access terminal proceeds with call set-up for the call attempt irrespective of whether the access network grants the QoS resource request. Alternatively, the access terminal waits for an extended period of time before the call attempt is permitted to fail. In a further example, in the event of call failure, the access terminal can refrain from informing a user thereof of the call failure. In another embodiment, the access network can respond to the QoS resource request with an allocation of a lower level QoS resources than requested if the requested QoS resources are not available. The access terminal can likewise be permitted to participate in the call with the lower level QoS resources.

Abstract: An embodiment is directed to displaying information to a user of a communications device. The communications device receives a query including a social parameter, a temporal parameter and a spatial parameter relative to the user that are indicative of a desired visual representation of a set of data objects. The communications device determines degrees to which the social, temporal and spatial parameters of the query are related to each of the set of data objects in social, temporal and spatial dimensions, respectively. The communications device displaying a first visual representation of at least a portion of the set of data objects to the user based on whether the determined degrees of relation in the social dimension, temporal dimension and spatial dimension satisfy the respective parameters of the query.

Abstract: A random backoff time can be determined and the transmission of an initial access probe can be delayed for the random backoff time. A backoff interval can be determined based on channel load, wherein the backoff interval defines a range from which the random backoff time is selected.

Abstract: A system and method for minimizing latency for direct group communications, such as push-to-talk (PTT) calls, among a group of wireless telecommunication devices on a wireless telecommunication network. The wireless telecommunication device has a dormant state without an open dedicated traffic channel for communications therefrom and an active state in which the wireless devices opens a dedicated traffic channel for an outgoing communication from the wireless telecommunication device, to include a direct communication stream. Either the wireless telecommunication device or an intermittent communication server for group communication streams can buffer the initial communication data of a group communication stream while the sending and/or receiving wireless telecommunication device changes from a dormant state to an active state with an open dedicated traffic channel.

Abstract: Systems and methods for two-tier backoff interval randomization are presented. An initial message transmission can have both a chip level and an access cycle duration level backoff applied to avoid potential collisions. Additionally, improved transmit power calculations and the random backoff can be combined to further improve the probability of a successful message reception and decoding.

Abstract: Embodiments are directed to determining whether one or more physical user interactions are present, at a wireless communication device, that indicate a near-future potential communication session resource request. Before the determination, a communication interface of the device is in a dormant state characterized by the device not being permitted to engage in a communication session with a wireless communication network. The device transitions the communication interface, after the determination, from the dormant state to an active state. In the active state, the device performs one or more actions to reduce a delay associated with a transmission of the potential communication session resource request in the event that the potential communication session resource request is actually transmitted by the device. For example, in the active state, the device can power-up or wake-up a radio bearer or modem to reduce a delay before transmission of the potential communication session resource request.

Abstract: Systems and methods for bundling signals in a wireless communication system are disclosed. A connection request and a reservation for QoS resources can be bundled into an access message at an access terminal. The access message with the bundled communication signals can then be transmitted to an access network. An application layer (e.g., a DataOverSignaling (DOS)) message can also be bundled with the connection request and the reservation into the access message.

Abstract: A system and method enable a wireless device to support simultaneously multiple push-to-talk (PTT) communications and interrupt certain PTT communication with higher priority ones. A user subscribes to multiple PTT communication groups and designates one of the groups as the primary group. The wireless device receives and plays PTT communications from the multiple PTT communication groups and interrupts playing of a PTT communication from a non-primary group if a PTT communication is received from the primary PTT communication group.

Abstract: An access network receives a request from an access terminal for communication session support resources associated with a communication session, determines whether sufficient communication session support resources are available for allocating to the access terminal and selects communication session support resources from another access terminal for de-allocation, the selected at least one communication session support resource associated with a communication session having a lower priority than the communication session. The access network sends instructions to the at least one other access terminal to facilitate de-allocation of the selected communication session support resource, and allocates communication session support resources to the access terminal for supporting the communication session after the selected communication session support resource is de-allocated from the other access terminal.

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: MIP forwarding methods are described that use additional access link-layer identifiers and redirecting data packet identifiers to provide unambiguous forwarding through the MIP Foreign Agent when the Mobile Node has multiple Home Addresses, and/or when the Home Agent, or some intermediate MIP node between the Foreign Agent and the Home Agent, supports multiple pools of home addresses from overlapping address spaces. New identifiers are used to ensure that sufficient forwarding information exists in conjunction with the information in transmitted packets, to uniquely identify each packet flow. Each packet flow is a globally unique quartet of the MN identity, the HA, the HA address pool and the HoA.

Abstract: A system, method, and wireless communication device that allow the transmission of secondary data in a group-communication data stream between wireless communication devices across a wireless communication network. The wireless communication device selectively transmits at least group-directed voice communication data to other members of a communication group, such as a push-to-talk (PTT) group, in a communication channel having a limited bandwidth thereof, and can selectively transmit secondary data in the same communication channel. A group-communication server preferably receives the voice communication data and secondary data and selectively transmits at least the voice communication data to other member wireless communication devices of the communication group.

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.
