Abstract: A methodology to automatically measure network parameters relating to wireless network environments is disclosed. First, if a server's telephone number is detected from power-on registration data stored in a storage device, then a connection with the server is attempted through a mobile station with a data service function using the server's telephone number. Thereafter, if there is test plan from the server after the connection is made, the network parameters is measured using another mobile station with a diagnostic monitor function based on the test plan data. The measured network parameters is then collected and parsed to obtain sets of measured network parameters, each set having a different kind of measured data; and the sets of measured network parameters are transmitted to the server using the mobile station with the data service function when there is a data transmission request from the server or it is time for data transmission.

Abstract: Disclosed is a method for optimizing forward link coverage in a spread spectrum communication system, e.g., CDMA system. Spread spectrum test communication signals are transmitted from a base station at a known power level, using an antenna having a known beam direction. Orthogonal channel noise is simulated in order to model noise generated by wireless communication traffic existing in an operational communication system of many subscribers. A mobile station receives the test communication signals in a specific region of a cell, and measures signal quality parameters, e.g., RSSI, Ec/Io and a forward frame error rate (FFER), from the received signals and simulated noise. The measured signal quality parameters are compared to respective criteria. Each region is designating as being satisfactorily covered by the base station if the measured signal quality parameters substantially satisfy the criteria.

Abstract: A method of forward power control in a cellular mobile telecommunication system having a base station and a mobile station, a base station receives an information about the quality of a forward link from a mobile station and controls the transmission power in the forward link. If information about the quality of the forward link is not obtained within a predetermined period due to deterioration in the forward link, the base station changes its parameters of the forward power control. As a result, the digital gain of transmission power of the forward link is increased to improve the deteriorated quality of the forward link and to carry out the forward power control. Simultaneously, the base station decreases the digital gain of transmission power more rapidly to saving a power consumption and to reduce interference to other radio channels.

Abstract: The present invention discloses a method for improving a call quality by increasing the output of a mobile station over the reverse link by adjusting threshold range of a system's predetermined E.sub.b /N.sub.o value in the event that the transmission output of the mobile station is stopped in a reverse power control of a cellular system, and by comparing the measured E.sub.b /N.sub.o ratio to a predetermined threshold E.sub.b /N.sub.o ratio to increase/decrease the mobile station transmit power. The method includes steps of adjusting the predetermined threshold E.sub.b /N.sub.o ratio by monitoring the call quality in a forward frame, and repeatedly increasing/decreasing the mobile station transmit power accordingly.
