Abstract: An exemplary method for providing presence detection in a communication system includes associating the identity of a first entity participating in the communication system, with a communication link of the system, and providing access to information regarding the first entity to other entities participating in the communication system. An exemplary method can further include receiving an indication of an incident, including a class or magnitude of the incident, accessing a list of users authorized to participate in the communication system, based on the indication, and denying users absent from the accessed list, access to the communication system. The last communication mechanism or communication address used by each authorized user can also be determined, and displayed.

Abstract: A method for detecting and transporting dynamic presence information over a wireless and wireline communications network comprises determining client device capabilities relating to user presence information that may be obtained from the client device and determining a presence configuration of the client device. The presence configuration defines information to be provided to a presence agent. The presence configuration also defines one or more action to be performed upon notification of an event occurrence. The method also includes collecting dynamic presence information based at least in part on the client device capabilities and the presence configuration.

Abstract: A communication gateway for communicating presence information between a connectionless packet-switched signaling network and an Internet Protocol (IP) network includes a message bearer configured to receive and send messages over a connectionless packet-switched signaling network and a translator, in communication with the message bearer, operable to translate messages received from the connectionless packet-switched signaling network into messages suitable for transport over an IP network and operable to translate messages received from the IP network into messages suitable for transport over the connectionless packet-switched signaling network.

Abstract: A grantor issues a trustable electronic document for the benefit of a requestor.
