Abstract: A conferencing system provides the scheduling of virtual meetings with meeting lobbies so that a meeting presenter can conduct a virtual meeting without the need to send out invitations to attendees. A person that wants to conduct a virtual meeting can schedule with the conferencing system a meeting with a meeting lobby. The meeting lobby has an address, but there is no associated privileged information, such as a meeting password. Would-be meeting attendees use the meeting lobby address to enter the meeting lobby as visitors in the lobby, and request to enter the meeting from the meeting lobby. A meeting presenter can then either grant authorization for a visitor in the meeting lobby to enter the meeting, or deny authorization for a visitor in the meeting lobby to enter the meeting. If a visitor in the meeting lobby is denied authorization to enter the meeting from the meeting lobby, the conferencing system removes the visitor from the meeting lobby.

Abstract: A method and system for optimally scheduling a web conference managed by a web application. Date and time ranges are initialized with predefined values. A tentative start date included in the date range and a tentative start time included in the time range are automatically calculated, and are included in a tentative schedule for the web conference. A time period is determined by the tentative schedule and a duration of the web conference. The automatic calculation prevents the time period from overlapping a time interval during which processors utilized by the web application are to experience a peak load. The tentative schedule is presented to the user via the interface, and is recalculated and redisplayed in response to the user updating a load-related parameter. The user selects a final schedule, which is the tentative schedule or a user-specified schedule different from the tentative schedule.

Abstract: The present disclosure discloses a method for implementing a Push to talk over Cellular (PoC) service and a PoC gateway so as to shorten the process for a terminal to implement a PoC service.

The present disclosure also discloses a PoC gateway. With the present disclosure, the application of the PoC service will be wider.

Abstract: A system and method are described for initiating and conducting a data conference between a plurality of conference endpoints linked in communication by a private or public computer network. A first conference endpoint then sends a conference initialization request to a dedicated conference server coupled to the computer network. Upon receipt of the conference initialization request, the conference server responsively generates a conference code uniquely identifying the conference and transmits the code to the first conference endpoint. The first conference endpoint subsequently converts the received conference code to a form (such as a string DTMF tone) which can be transmitted by in-band audio to other conference endpoints. The other participating conferencing endpoints, after receipt of the conference code, are configured to log on to the conference server using the conference code.

Abstract: Techniques for minimizing call setup latency are disclosed. In one aspect, a channel assignment message is sent with a flag to direct the use of previously negotiated service parameters. This aspect eliminates the need for service negotiation messages. In another aspect, a channel assignment message is sent with an active set identifier instead of an active set and its parameters. This aspect reduces the transmission time of the channel assignment message. In yet another aspect, call setup without paging is facilitated by a mobile station (106) sending a pilot strength measurement message between active communication sessions, such that a channel assignment message can be used for mobile station terminated call setup without the need for mobile station paging and related messages.

Abstract: A method for terminating a communication session is present. During a communication session in which communication devices are in communication through a server, one of the devices decides to terminate the session. This device generates a first message requesting permission to terminate participation in the session and sends it to the server. The server, receiving the first message, determines whether or not there is session media being communicated or pending communication to the device. If not, the server generates a second message authorizing the device to terminate its participation in the session and sends it to the device. The device continues to listen for session media until, upon receiving the second message, it terminates its participation in the session.

The ICCBM system then calls the customer, calls the party or parties, and the audio signals are bridged in a manner that optimizes the call signal to noise ratio, minimizes demands placed on computing resources, and provides controls with which the customer may monitor and control the telephonic access of the other participants through the duration of the conference call.

Abstract: The present invention discloses a method and an apparatus for controlling user's participation into a session so that the system can control accession to a PoC session requested by anonymous users and restrict an expelled user from joining the session again. Under the present invention, a client in the PoC session sends a request of expelling a user to the control server, with the SSRC identifier or nickname of the user or an anonymous user wildcard carried in the request; according to the received SSRC identifier, nickname or anonymous user wildcard, the control server searches for the corresponding PoC address, and expels the user out of the session as required according to the PoC address. Therefore, the client with the expulsion right can control accession to the PoC session requested by other users, especially anonymous users, thus keeping order of the session.

Abstract: To automatically determine the availability status of the user of a handheld communication device, various selected conditions of the device may be checked, which imply whether or not the user is likely Available, or Unavailable or the equivalent. Normally, the selected conditions are checked only if the user has not explicitly or semi-explicitly set his or her status to Unavailable. The conditions to be checked can vary widely, but generally include anything from which it might be inferred or implied that the user is likely either Available or Unavailable or the equivalent. Such conditions can include, for example, whether or not a specified timeout for use of a keypad, trackwheel or other mechanical feature of the device has elapsed yet; whether or not a real-time application is in use; and preferably any one or more of a variety of other conditions, one further example being whether or not there are any unattended-to notifications such as an unanswered phone call, or a missed e-mail, SMS or other message.

Abstract: A method and system for peer-to-peer communication among a plurality of sites in a land mobile radio (LMR) system. The sites are interconnected by a data network, such as an IP network. Each site transmits a periodic broadcast message, which includes the identity of the transmitting site and a list of target groups that the transmitting site is interested in participating. The message is received by the other sites, thus each site becoming aware of the presence of all other sites in the system and Talk Groups they are interested in. When a site, referred to as the initiating site, intends to communicate with other sites, the initiating site transmits a call request message. The call request message is multicast over the data network to the intended recipients. The initiating site receives an acknowledgement message from the other sites confirming their willingness to communicate with the initiating site.

Abstract: A method and apparatus are provided for processing a request to instigate communication, received by a routing device associated with a plurality of terminals. The request relates to a communication to be established between a sender device of the request and at least one of the terminals. The method includes a step of comparing communication capabilities of said sender device with respective communication capabilities of one or more terminals, called addressee terminals, which are able to establish said communication, so as to identify at least one terminal having capabilities making it possible to establish with the sender device a communication of maximum quality. A call notification is transmitted to at least one of the addressee terminals, which is suitable for triggering on the addressee terminal a call presentation prompting a user to use, by priority, one of the terminals identified during the comparison step to establish the communication.
