Abstract: The present disclosure relates to a multi-site, multi-location, three dimensional video conferencing system that incorporates at least one conferencing apparatus that is operatively coupled with a server (say in the cloud), wherein the conferencing apparatus enables user's own smartphones and/or tablets to be inserted/detected therein to enable conferencing to take place.

Abstract: One detects (101) an indication from an initiator of a presently supported ad-hoc conference call who seeks to transfer chairmanship of the presently supported ad-hoc conference call to another conference call participant. The chairmanship is then transferred (102) to this other participant to thereby provide a presently supported ad-hoc conference call having a transferred chairman.

Abstract: During a communication session (101) for a multi-network user platform (which communication session is presently occurring in a first network and is terminable by a Session Initiation Protocol server as comprises a part of that first network), one establishes (102) in the first network a Session Initiation Protocol instance as corresponds to the communication session. Thereafter, and particularly following a handoff of the communication session from the first network to a second network, one uses (104) the Session Initiation Protocol instance to maintain communications with the Session Initiation Protocol server such that the Session Initiation Protocol server does not terminate the communication session.

Abstract: During (101) a communication session for a plurality of user platforms wherein at least one of the user platforms is on hold and wherein the communication session is presently occurring in a first network and is terminable by a Session Initiation Protocol server as comprises a part of that first network, one establishes (102) in the first network a Session Initiation Protocol instance as corresponds to the communication session wherein the Session Initiation Protocol instance comprises, at least in part, session context information for the user platform that is on hold. Then, following a handoff of bearer support of the communication session from the first network to a second network, one uses (104) the Session Initiation Protocol instance to maintain the hold status of the user platform that is on hold with the Session Initiation Protocol server subsequent to the handoff such that the Session Initiation Protocol server does not terminate the communication session.

Abstract: Fixed network equipment associated with a given private branch exchange provides, and a mobile communication device receives, information that corresponds to compatible interoperation with that private branch exchange, including, for example, a plurality of identifiers including a logical identifier that corresponds to compatible interaction with the private branch exchange. Thereafter, when seeking facilitation of services via that private branch exchange, the mobile communication device can use that logical identifier.

Abstract: A CDMA base site provides dispatch group call service to members of a dispatch group by using a first long-code mask. The base site also repeatedly transmits the group call's channel assignment so that a scanning communication unit can detect that the call is active. In order for the scanning communication unit to decode the dispatch communication once the call is detected, it requests a long-code mask transition from the base site. The base site then transmits a new long-code mask and begins encoding the dispatch communication using the new mask. Thus, the scanning communication unit is able decode the communication and thereby join the active CDMA dispatch group call.
