Abstract: A method for performing session merging between PoC sessions under the environment of multiple PoC sessions is provided. A merging PoC client sends a request for the session merging with a merged session to a PoC server managing a merging session to which the PoC client belongs. The PoC server managing the merging session sends a session merge request to a PoC server managing the merged session. Negotiation of a CF (Controlling PoC Function) for managing a session to be merged is performed between the PoC server of the merging session and the PoC server of the merged session. When an entire CF of the session to be merged is selected as the negotiation between the PoC servers is completed, the PoC server of the merged session sends an UPDATE message of modified media parameters to a PoC client of the merged session.

Abstract: A conference bridge adapter for processing data carried on a media path between, on the one hand, a conference bridge operative to communicate composite packets carrying media information and auxiliary information pertaining to the media information and, on the other hand, an endpoint characterized by an inability to exchange composite packets with the conference bridge. In one direction, a stream of composite packets is received from the bridge. An output media stream without auxiliary information is generated from the media information in each received composite packet. In the opposite direction, a stream of packets carrying only media information is received from the endpoint. Auxiliary information is derived from the media information and a stream of composite packets is generated by combining the media information and the auxiliary information. Thus, a media conference can be established between seemingly incompatible network elements.

Abstract: In the various embodiments of the present invention, a method of floor control in a PTX communications system comprises transmitting a floor control message via a floor control channel (905) wherein the floor control message consists of media designation fields (1003) for any possible requested media type.

The Real Time Control Protocol (RTCP) may be used for the floor control messaging channel and is independent from the requested media streams (217) which are typically Real-time Transport Protocol (RTP) media streams. Support may be provided for older mobiles that do not support each type of RTP media stream, but will still receive and interpret the RTCP floor control messaging, which in the embodiments of the present invention, is common for all media types.

Abstract: A visual interface for a PTT user terminal displays user images of participants in a PTT conference. When a PTT conference is established, a controller determines whether an image associated with each participant invited to the PTT conference is stored in memory on the user terminal. For each participant that has an associated image stored on the user terminal, the controller displays the image. For those participants that do not have an associated image stored on the user terminal, the controller generates and sends a request for the image. Upon receipt of the image, the controller displays the image on the user terminal. During the PTT conference, the controller alters the appearance of the images to show the status information of each participant, such as which participant has floor control and presence of participants.

Abstract: A calibration procedure of wireless networks to create a topology map mainly consists of two phases: a measurement phase during which each wireless device, i.e. all mobile terminals end the central controller, transmits a calibration signal in broadcast mode (S2, S3, S4) and each other wireless device measures the received signal quality and the reporting phase during which each mobile terminal reports the measured results to the central controller of the network (S6, S7). Both of these phases are preferably initiated by the central controller, the measurement phase with the broadcast of a measurement control signal to all mobile terminals (S1) and the reporting phase with the broadcast of a reporting control signal to all mobile terminals (S5). Based on all measurement results the central controller creates a topology map of the network once all reports have been received.

Abstract: To allow a user to break out of a conference and rejoin it, multiple accessions within a predetermined period (such as one day) may be counted as a single accession in counting towards the predetermined number of accessions. Different users may be validated for use of the same resources for different durations. To encourage responsible use of the reservation facilities, allocation of resources may be prioritized for users having the most restricted duration of access. A telecommunications conferencing facility may include a provisioning facility for allocating resources to a user and a validation processor for creating validation information. The provisioning facility and validation processor control access to the resources such that a user is permitted access to the resources for a predetermined duration. A timer and/or counter may be employed to disable access after elapse of a predetermined period or number of accessions.

Abstract: Stored in an each speaker's sound volume coefficient table 13 are a speaker identification ID and information of a voice coefficient so as to be correlated with each other. A speaker identification unit 11 extracts an each speaker's ID from a received packet based on floor control information or outputs the packet as an RTP packet to an RTP buffer. A sound volume control unit 12 executes a control program 14a of a recording medium 14 to record a current speaker identification ID and reads a sound volume coefficient relevant to the speaker identification ID from the each speaker's sound volume coefficient table 13 to output the coefficient as sound volume control information. In this case, the sound volume control unit 12 increments/decrements the relevant sound volume coefficient based on sound volume adjustment information of a sound volume adjustment unit.

Abstract: A method for establishing multicast PoC communication is disclosed. To establish multicast PoC communication, a multicast-join process will be coupled with a PoC session setup process, and the PoC server will function as a multicast content server, to multicast PoC communications to the PoC session participants. For example, when a party initiates a PoC session, the PoC server may acquire a multicast flow-ID from a multicast session manager, and the PoC server may convey that multicast flow-ID to each participant within the PoC session setup signaling. Upon receipt of the multicast flow-ID, each participant may then engage in signaling with the multicast session manager, to join the associated multicast group. And the multicast session manager may direct the PoC server to begin multicasting the associated flow to the group members, which the PoC server will do once it begins receiving PoC bearer data from one of the PoC session participants.
