Mobile terminal and base station in a packet radio services network
PURPOSE: A mobile terminal and a base station in a packet radio services network is provided to obtain a high degree traffic channel by using the same number of wireless channels. CONSTITUTION: A mobile terminal has a communication between the mobile terminal and a base station(22); a digital coding of voice for providing voice information; an assembling speech information to a speech packet; and a processor determining one of a plurality of channels for the generation of a channel allocation requests for a channel in which to send speech packets. A radio transmitter(8) is provided to transmit the channel allocation request and the packet to the base station of the network. A radio receiver(10) receives the equivalent of the channels allocated by the base station for a mobile terminal to be transmitted. The processor is reactive to the channel allocation for determining whether the packet is transmitted to the allocated channel.
Abstract : The purpose of this thesis is to evaluate the systems engineering effort by the Aviation Research and Development Activity (AVRADA), the Airborne Engineering Research Activity (AERA), and support contractor DOSS to install the Trimble Global Positioning System (GPS) receiver onto Army helicopter platforms. This study is an example of a successful systems engineering effort to install a non-developmental item (NDI) onto existing aircraft platforms in response to an urgent requirement created by the deployment of aircraft for Operation Desert Shield.
