Abstract

Currently, the Portuguese Army has the military transceiver Radio Multifunctional GRC-525 which equips the tactical units within the operational component of the ground forces system. This equipment provides to the ground forces the ability to establish secure communications. The current version of the Radio Multifunctional GRC - 525 provides a transparent integration with IP data networks and, specifically with IP telephone systems through the SIP protocol. The Radio Multifunctional GRC - 525 allows bidirectional radio calls, however the confidentiality between the members of the network and simultaneity of communications are not assured, this happens because the communication is established over a shared radio frequency and on a given radio network at a time, only one user can transmit a message while the others are only in reception mode (half-duplex system). To solve these limitations, was developed Radio Multifunctional GRC - 525 Communications Control and Management System, which allows users within command posts to establish a call with any entity that is carrying out its operational activity operating with the Radio Multifunctional GRC - 525, regardless of the radio network it is in, ensuring the confidentiality and the simultaneity of communications. The present system has other features, among which are the recording of all calls to allow backbriefing, as well as the creation of a history with all events resulting from actions performed by the entities that use it.
