摘要： A system and method are described for determining when to exit an existing wireless communication coverage network. The method samples the device geographical position, determines a threshold boundary line, measures the position of each sample point with respect to the threshold boundary line, and, beginning at a predetermined initial value, maintains a running sum in response to measuring position. The existing coverage network is exited when the running sum is greater than or equal to a predetermined terminal value.

摘要： A system and method are presented for determining when to exit an existing wireless communications coverage network. The method samples the device geographical position, determines a threshold boundary line, measures the position of each sample point with respect to the threshold boundary line, and, beginning at a predetermined initial value, maintains a running sum in response to measuring position. The method uses the threshold boundary line to partition a coverage area for the existing coverage network into first and second zones. Then, the method decrements the running sum for sample point positions in the first zone and increments the running sum sample point positions in the second zone. The method exits the existing coverage network when the running sum is greater than or equal to a predetermined terminal value and then resets the running sum to the predetermined initial value.

摘要： An automated software re-testing system for efficiently validating proper operation according to a specification. Regression tests are automatically created in an object-oriented system. The inheritance hierarchy of the system is used to determine which system classes should be tested. Regression test class destructors are used to test dependent classes. Unchanged system classes, and those dependent entirely on unchanged system classes need not be tested and time and effort are saved by skipping their re-testing.

摘要： A novel and improved digital FM audio processor for use in a dual-mode communication system selectively operative in either FM or code division multiple access (CDMA) modes. Analog voice or voice-band data is input to a speech encoder/decoder (CODEC) which converts the analog signal to a digital signal. The digital FM signal is read from the CODEC, filtered, compressed, up-sampled and combined with a transponded SAT signal and then modulated for RF transmission. On the receive side, the FM analog signal is received, demodulated, down-sampled, expanded, and filtered before being converted to the proper format (&mgr;-law, a-law, or linear) for the speech CODEC. The CODEC then converts the digital FM audio signal into an analog waveform for conversion to sound. By performing the FM audio processing digitally, the same digital signal processing (DSP) firmware may integrated on the same application specific integrated circuit (ASIC) which is capable of performing audio processing of both FM and CDMA audio signals.

摘要： A mobile communication method is a method for distributing MBMS data to a mobile terminal in a mobile communication system including a general cell supporting a broadcasting of the MBMS data and a specific cell not supporting the broadcasting of the MBMS data. The mobile communication method comprises a step of controlling not to set a frequency used in the specific cell to a highest priority of cell selection, at the mobile terminal, when the mobile terminal receives the MBMS data broadcasted from the general cell in an idle state and a frequency used in the general cell is different from the frequency used in the specific cell.
