| 20100020745 | METHOD FOR DISTRIBUTING MEDIA IN AN INFRASTRUCTURE BASED COMMUNICATION SYSTEM - A wireless communication device acquires membership in a predefined group, joins an ad hoc network associated with the predefined group, and joins and participates in a first session established through an infrastructure device for distributing media to the predefined group. If the wireless communication device is a duplicator node for the ad hoc network, then it receives the media from the infrastructure device and distributes the media other nodes of the ad hoc network, otherwise it receives the media from the duplicator node. The infrastructure device identifies the duplicator node for each ad hoc network associated with the predefined group and each member of the predefined group that is not a node of any of the ad hoc networks and distributes the media only to these members of the predefined group. | 01-28-2010 |
| 20100071027 | METHOD OF PROVIDING A MIXED GROUP COMMUNICATION SESSION - A method of providing a mixed group communication session for a mixed group containing protected users and a guest user is provided. The method uses a secure server to assign temporary Identities (IDs) to the protected users. The secure server forms a mixed group session containing desired participants from among the protected users and the guest user. The secure server provides limited group rights to the guest user in the mixed group session. During the mixed group session, the secure server uses the permanent IDs of the protected users towards other protected users and temporary IDs of the permanent users towards the guest user. Also provided is a method for providing a mixed group communication session for a mixed group containing protected users and a guest user, wherein temporary IDs are assigned to protected users and the guest user. | 03-18-2010 |
| 20100234057 | METHOD AND DEVICE FOR ENABLING SELECTIVE PRIVACY IN A PUSH TO TALK (PTT) WIRELESS GROUP COMMUNICATION SESSION - A method and device for enabling selective privacy in a push to talk (PTT) wireless group communication session provides improved control over sharing of user identity information. The method includes processing at a PTT server a request for selective privacy. The PTT server then processes one or more selective privacy parameters, whereby at least a first session participant is enabled to receive an identification of a second session participant and a third session participant is not enabled to receive an identification of the second session participant. The PTT server then facilitates the PTT wireless group communication session between at least the first session participant, second session participant, and third session participant according to the one or more selective privacy parameters. | 09-16-2010 |
| 20100248680 | SYSTEM AND METHOD FOR CONTROLLING USE OF UPLINK RANDOM ACCESS CHANNELS (RACHS) BASED ON MULTI-DIMENSIONAL SUBSCRIBER CLASSIFICATION - Systems and methods are provided for controlling use of uplink random access channels (RACHs) based on multi-dimensional subscriber classification. These systems and methods are useful in cellular communication networks that implement, for example, a public safety cellular system. | 09-30-2010 |
| 20100332647 | METHOD AND SYSTEM OF UPDATING PRESENCE INFORMATION IN A COMMUNICATION SYSTEM - In implementing a method of updating presence information for a plurality of presentities in a communication system, a presence server: defines a group of presentities that share the same value for a first presence attribute; receives an update of the value of the first presence attribute for one of the presentities in the group; and applies the update of the value to all of the presentities in the group. | 12-30-2010 |
| 20110047558 | METHOD FOR PRESENCE INFORMATION SUBSCRIPTION IN A GROUP COMMUNICATIONS SYSTEM - In a group communications system, a group watcher module subscribes to presentities of interest for a particular group by communicating, to at least one presence server module, a set of subscriptions to a plurality of presentities, wherein each subscription contains a set of event notification criteria for a presentity. When the group watcher module detects a change in presence information for the set of subscriptions, it determines current members of the group and distributes the change in presence information to the current members. | 02-24-2011 |
| 20110074579 | METHOD FOR USING RECORDING RULES AND PREVIOUS VALUE SELECTION RULES FOR PRESENCE INFORMATION IN A COMMUNICATIONS SYSTEM - In a communications system, a presence server maintains and distributes presence information in accordance with recording rules and previous value selection rules. The presence server: associates a recording rule with each presence information element in a subset of a plurality of presence information elements for a presentity; maintains a set of previous values according to the recording rule associated with the presence information element, for each presence information element in the subset; receives an initial subscribe request from a watcher for one or more presence information elements in the subset; and in response to the initial subscribe request, notifies the watcher of a number of the previous values maintained for each presence information elements in the subscribe request, wherein the number of the previous values that is sent is determined by a previous value selection rule associated with each presence information element. | 03-31-2011 |
| 20110151917 | METHOD AND APPARATUS FOR BRIDGING CALLS BETWEEN TWO DISPARATE PUSH-TO-TALK SYSTEMS - A PTT bridging gateway between a first PTT system and a second disparate PTT system: receives an invitation to a first client to join a first group call for a first group comprising multiple member clients on the first PTT system, wherein the first client is one of the member clients of the first group; determines that the first client is mapped to a second group comprising multiple member clients on the second PTT system; and initiates a second group call to the multiple member clients on the second PTT system. | 06-23-2011 |

Based on the request, the communication server establishes a set of privacy rules related to the second participant that control sharing of identity information between the second participant and a third participant of the communication session. | 06-23-2011 |
| 20110158184 | METHOD AND APPARATUS FOR RESOURCE ALLOCATION IN A SHARED WIRELESS NETWORK - Resource allocation is performed in a shared wireless network that includes multiple cells, a shared wireless network QoS manager, and multiple local QoS managers. The shared wireless QoS manager receives from multiple ones of the local QoS managers on a per cell and per QoS service class basis (for a plurality of QoS service classes): an aggregation of current cell usage estimations; an aggregation of cell load level indicators, and an aggregation of additional resources needed. Using this received information, the shared wireless network QoS manager: determines a total capacity of each cell that is needed to satisfy a total resource need on a cell by cell basis for the local QoS managers; and based on a maximum capacity for each cell, allocates to each local QoS manager a percentage of their total resource need. | 06-30-2011 |
| 20110161397 | METHOD FOR PRESENCE NOTIFICATION BASED ON A SEQUENCE OF EVENTS - A client entity generates a subscription to a presentity that includes a sequence of events which define a trigger that controls when a presence server sends a notification to the client entity; and the subscription further indicates a time period parameter for the sequence of events. Upon receiving the subscription, the presence server receives and monitors presence information based on the indicated time period parameter to detect an occurrence of the sequence of events, and sends the notification to the client entity when the presence information satisfies the trigger. | 06-30-2011 |
| 20110161399 | METHOD AND APPARATUS FOR DETERMINING A COMMUNICATION TARGET AND FACILITATING COMMUNICATIONS BASED ON AN OBJECT DESCRIPTOR - A server performs a method for determining a communication target and facilitating communications with the target based on an object descriptor. The method includes the server receiving, from a requestor in a communication system, an object descriptor for an object, a description of a relationship between the object and a target in the communication system, and a request for a communication action with the target. The server then determines the target using the object descriptor and the relationship between the object and the target and facilitates the communication action with the target. | 06-30-2011 |
