A scalable method and apparatus for performing a mashup of military Situation Awareness (SA) data in a tactical data link (TDL) with data residing in several databases, using a web server-web browser architecture over an IP-based network. In a preferred embodiment the invention employs a TDL gateway to collect and correlate SA data from a TDL and stores the data in a track database, which is interfaced by a web server to the IP-based network. A SA web browser interfaces with the TDL gateway web server, a maps server and a symbology server to mash data from a plurality of sources into an integrated whole, allowing a more complete graphical representation of the SA data. The invention is capable of operating in reverse, to inject user defined data from the SA web browser into the TDL.

Method and representations for exporting tactical data link information as a web service

A Voice over Internet Protocol (VoIP) network is described in which session state is maintained in access switches, but not signaling gateways which maintain transaction state only during pendency of a related transaction. The signaling gateway further provides transparent inter-operation between the VoIP network and non-IP networks, such as the PSTN, by means of a translator which directly translates messages between the networks.

Voice over IP architecture

A method for forming channelized groups in a wireless communication network having a plurality of nodes. At least one node in the network is assigned to a first channel that is associated with a channelized group having a first set of nodes. The method determines whether there is contention between the at least one node and the first set of nodes. In addition, the method includes switching the at least one node from the first channel to a second channel based on the contention determination.
