Abstract: A wireless network terminal tunes to a high data rate (“HDR”) HDR carrier when in an idle state. The terminal periodically scans a 1×RTT carrier for pages, SMS and other information. Should the scan detect an incoming communication on the 1×RTT carrier, any existing HDR packet session is terminated so that the terminal may tune to the 1×RTT carrier to receive the incoming communication. If the coverage area does not support an HDR carrier, the terminal tunes to the 1×RTT carrier and periodically scans for an HDR carrier.

Abstract: The present invention provides systems and methods for coordinating calls within hybrid cells that support both an all services carrier and a best-efforts carrier, wherein the all services carrier supports real-time and non-real-time services and the best efforts carrier supports only non-real-time services. In one embodiment of the invention, the all services carrier is a 1×RTT carrier and the best-efforts carrier is an HDR carrier. Calls may be placed on either carrier and transferred between the carriers as circumstances dictate. In addition, the present invention provides systems and methods to dynamically determine the most appropriate carrier for a given call.

Abstract: In a base station of a mobile cellular telephone system of the type having time division multiple access (TDMA) channels, a radio frequency test loop is established between a predetermined downlink channel of a base station transmitter and a predetermined uplink channel of a base station receiver. The test loop is in real time, thereby eliminating the time offset of the radio channels used for communications. The radio frequency test loop includes a circuit for transposing the frequency of the carrier signal from the transmitter to a frequency that can be received by the receiver. The signal having the transposed frequency is used in tests for determining values such as bit error rate (BER), transmission signal level, or reception sensitivity.

Abstract: A malfunction position detection system is disclosed for a modular telecommunication facility. Each telecommunication facility is constructed out of a plurality of modular cabinets which are positioned in a station rack. The malfunction position detection system includes switches for setting the position of each cabinet in the station rack. The cabinet position is read off of a bus connected to the switches by a plurality of electronic units connected to the cabinet. The cabinet position is stored in some of the electronic units. As a result, the cabinet position can be sent along with an error message to the cellular system when an error occurs.
