Abstract: Enhanced system operation is realized with a method, and apparatus for carrying out the method, which negotiates with a customer for a Quality-of-Service level that the customer gets in a connection for a price that the customer is willing to pay. The negotiation is repeated throughout the time the connection exists. In a cellular environment, the QoS is negotiated when a mobile unit initiates a call, at regular intervals during the call (when changes in traffic conditions call for a renegotiation), and when the mobile unit is handed off from one cell to another cell. To prepare for its end of the negotiations, the service provider collects information concerning the level at which its resources are being utilized and determines its ability to guarantee a particular QoS level. This information is continuously updated and combined with historical data to calculate price data.

Abstract: A low-noise amplifier capable of operation in two or more frequency bands of a personal communication services (PCS) receiver or other wireless communication system terminal. An exemplary embodiment of the amplifier includes a single bipolar junction transistor amplification stage. Input and output matching networks for the transistor each include a first series capacitor, a shunt inductor coupled to ground potential, a second series capacitor and a second inductor coupled to a supply voltage. These four elements are used to provide narrowband input or output matches in two distinct frequency bands, such as 900 MHz and 1.8 GHz. The first series capacitors in the input and output matching networks may also be used to provide DC input and output isolation, respectively, and the second inductors of the input and output matching networks may be used to supply DC bias to the base and collector, respectively, of the amplifier transistor.
