Abstract: Methods, devices and systems enable efficient organizations of group communications on a mobile device. The mobile device may be configured to receive location information from other mobile devices in a communication system, determine the current location and orientation of the mobile device, determine directions and distances from the mobile device to each of the other mobile devices, and generate a first-person perspective and/or top-down perspective display showing relative locations of the other mobile devices. Other multiple mobile devices may be represented in the display as images (e.g., icons, avatars, directional indicators, etc.). The display may provide a user interface to enable a user to quickly organize other mobile devices into groups and initiate group communications with some of the other mobile devices. The mobile device may be configured to group the displayed images into one or more communication units and establish communication links with mobile devices in the communication units.

Abstract: Disclosed are systems and techniques by which a caller may specify a callee's telephone number and be connected directly to a carrier provided voice mail facility associated with the identified the telephone number, even though the callee's carrier may not be the same as the caller's carrier. In the disclosed technique, a telephony server places a “Send a call” request to a server which then sends a signaling call that busies out the channel associated with the callee. The telephony server places a second call (the actual voice message) upon confirmation that the signaling call has been initiated, forcing the second call to the carrier's voice mail facility associated with the callee, since the first signaling call busied the first channel. Prior to sending the signaling call, a database look up is performed to determine which carrier services the callee number. Once the carrier is determined, another memory look up is performed to determine the time delay associated with that carrier.

Abstract: Communication between a requesting unit and target units in a wireless network is disclosed. Searching is performed to locate target units by comparing identifying information with information received by the requesting unit from a user.

Abstract: A device, system, and method are directed towards determining a start and/or an end time for a spontaneous event. A mobile device user creates a group for the spontaneous event, and sends the members an invite. During the event, members share media content and/or text messages with other members.

The start time may be based on when the group is created and/or revised when a flow rate of the media content and/or messages exceed a threshold. The end time may be based on the flow rate being less than another threshold. The location of the spontaneous event may also be determined based on a location of the member's mobile devices during the event.

Abstract: A system for facilitating short-range wireless data exchanges between apparatuses that are not linked by a wireless network connection. For example, an apparatus may initially determine if data suitable for transmission without first establishing a formal network connection is pending. For example, in terms of Bluetooth the data may suitable for transmission to another apparatus without having to first negotiate a Bluetooth piconet including both apparatuses.

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.

If sectors of the first and second clusters overlap, the network controls a manner in which the first and second clusters carry the multicast media.

Abstract: Improved group communications methods which are well suited for a wireless environment are described. End nodes request that access nodes make changes in group membership information maintained at the access node. The access node responds to the requests by a response signal indicating a grant or denial of the request. Requests may be to add or remove the end node, e.g., a mobile wireless terminal, from a particular group membership list identified in the request signal. The access node maintains a detailed list of group members and uses the information to control how signals, e.g., packets, are transmitted to the group members. Group membership information may be updated at the access node at the time of handoff and/or an end node enters the cell or otherwise changes its point of network attachment.

Abstract: A reception-process manager of a call server writes, in a transfer-voice-data storage, voice data contained in a voice packet received from the transmitter terminal which has acquired the talk right. A transmission-process manager of the call server determines the next transmission interval of a voice packet for each receiver terminal on the basis of determination information received from the each receiver terminal. The transmission-process manager reads out the voice data in a size dependent on the determined transmission interval from the transfer-voice-data storage, generates voice packet containing the voice data for the each receiver terminal, and transmits the voice packet to the each receiver terminal. Thus, the voice-packet transmission interval can be changed for each receiver terminal without stopping voice-packet transmission.

Abstract: Provided is a communication system which connects a unified C/U router to a network having C/U separation, wherein the stopping of U-plane communication of the unified C/U router is prevented even when the messages transmitted from a C-plane controller of the network having C/U separation do not arrive because of faults in the network having C/U separation. The routing information of a C-plane message (routing protocol) received by a U-plane controller is sent to an adjacent peer without being reflected in a routing table of the U-plane controller. The routing table of the U-plane controller is generated on the basis of the routing information (FIB information) received directly from the C-plane controller. In addition, a keep-alive packet from the unified C/U router is not sent to the C-plane controller and keeps alive the connection with the user router at the transmission destination.

Abstract: A radio access network (RAN) accumulates page messages in a paging buffer for subsequent transmission into a wireless coverage area. A buffer monitor is configured to periodically monitor the occupancy of the paging buffer and to detect when there is a surge in the paging buffer occupancy (e.g., when the occupancy increases by at least a threshold amount during an evaluation time period). When the buffer monitor detects a surge in paging buffer occupancy, the RAN transmits a control message that changes one or more access parameters that mobile stations operating in the wireless coverage area use to determine when to transmit responses to page messages. Because of the changed access parameters, mobile stations that receive page messages in the same time period are less likely to transmit responses in the same access cycle channel, thereby reducing the possibility of access probe collisions.
