The disclosure is directed to recording voice data transmissions between mobile communication devices. An embodiment of the disclosure receives, at a first mobile communication device, an indication that a subsequent voice transmission segment may or may not be recorded by at least one other mobile communication device, and transmits, from the first mobile communication device, an indication to said at least one other mobile communication device that the subsequent voice transmission segment may or may not be recorded. Another embodiment receives an indication from at least one other mobile communication device that a subsequent voice transmission segment may or may not be recorded by said mobile communication device, and if the received indication indicates that the subsequent voice transmission segment may be recorded, records at least a portion of the subsequent voice transmission segment, and stores the recorded portion in a memory associated with said mobile communication device.

A method for ascertaining active communication sessions may include receiving a request to ascertain active communication sessions by a communication session information server; transmitting respective challenges to determine whether communication sessions are currently active from the communication session information server to at least two communication session servers; receiving respective challenge responses from the at least two communication session servers, which indicate one or more active communication sessions controlled by the respective communication session server or indicate that such communication sessions currently do not exist, by the communication session information server; and transmitting a first response, which indicates one or more active communication sessions controlled by the at least two communication session servers or indicates that such communication sessions currently do not exist, by the communication session information server.

Architecture for a scalable, pluggable multi-party, and distributed multimedia conferencing. A centralized policy and control conferencing component allows the seamless plug-in of different distributed media components (e.g., data, audio/video, messaging) to accommodate client participation in a conference session. The centralized conference control component includes the following: a conference notification service for accepting subscriptions to the conference state and notifying subscribers about changes to that state; a conference policy and roster control service for storing and manipulating conference policy and rosters; a security service for user authorization/authentication based on user identity information; a scheduling service for conference scheduling; an allocation service for allocating the most available media component(s) for a conference session; and, an MCU management service for conference policy and roster management of the distributed media components.

摘要:
Push-to-talk messages are sent via a wireless multicast channel to multiple push-to-talk groups of devices regardless of group membership. Thus, all of the devices using the multicast channel receive all of the push-to-talk messages. To separate messages bound for one push-to-talk group from those bound for another, a push-to-talk group specific orthogonal code is applied to each message. The devices in a specific group use the group specific orthogonal code to decode the received multicast messages. If a device decodes the multicast message with the correct group specific orthogonal code, then the message is decoded and the device can play the message. If a device decodes the multicast message with a different group specific code (i.e., because it is not a member of the group the message was intended for), the message is will not be properly decoded and thus will be unplayable or scrambled.

Disclosed is a system and method for managing a user preference profile, and the system includes a plurality of application clients, a plurality of application servers corresponding to the plurality of application clients, and a shared server for storing and managing user preference profiles for respective applications. The application clients selectively activate the user preference profiles stored in the shared server and provide the selectively activated user preference profiles to the application servers. By storing user preference profiles for respective applications in one location in this way, the user preferences can be efficiently managed.
摘要:
In a method for determining active communication sessions, a request to determine active communication sessions is received. Queries as to whether communication sessions are currently active are sent to at least two communication session servers. The respective query answers that indicate one or more active communication sessions being controlled by the respective communication server are received. A first answer that indicates one or more active communication sessions being controlled by the at least two respective communication servers is sent. A communication session information server executes the method.

During operation, a push-to-talk (PTT) button will have a touch sensor incorporated on its surface. When the touch sensor detects a touch from a user, the apparatus will exit a low-power state and a display on the apparatus will provide PTT information.
