Abstract: A communication server has a message transfer unit that transfers messages between users operating under different, potentially non-compatible communication systems. A translator is connected to the message transfer unit. The translator translates messages sent to the message transfer unit into formats compatible with the different communication systems. A registration unit is used to associate communication systems with an incident. Communications between the different communication systems is restricted by incident and by registration. A voice/data mediator is used to conduct communication sessions through the message transfer unit. The communication sessions are conducted by the voice/data mediator between participants that are designated by a user. The participants are selected from users within communication systems that are registered with an incident.

Abstract: Under the present invention, when a request is received from a client device for a particular software application, the client device will first be interrogated to determine the device platform. Thereafter, the client device will be probed (e.g., from a remote bundle repository) to determine to determine its capabilities. Then, certain components of the requested application can be identified and configured to best take advantage of the client device's capabilities.

Abstract: A method and structure for a communication system has a first-level regional server connected to a first agency and a second agency, and a second-level regional server connected to a plurality of the first-level regional servers. The second-level regional server has a first connection for connecting to one first-level regional server. The invention also has a second connection for connecting to another first-level regional server. The invention also includes a global directory and a central processing unit.

Abstract: Disclosed is a communication server that includes a message transfer unit that transfers messages sent between a first user communicating under a first communication system and a second user communicating under a second communication system. For example, the communication systems could each comprise a plurality of mobile wireless transceivers and a plurality of land-based transceivers that are used by emergency-response organizations. These communication systems may be incapable of communicating directly with each other. The communication server also includes a translator connected to the message transfer unit. The translator translates messages sent from the first communication system into a format compatible with the second communication system and vice versa. The communication server also has a voice-over-Internet-protocol (VoIP) unit connected to the message transfer unit, so that messages are transmitted through the communication server in a VoIP format.
