Abstract: An apparatus and method for measuring the quality of a reverse link and the load of a base station (BTS) in a CDMA mobile telecommunication system. The apparatus and method periodically detect the power of a receiving signal from a mobile station to a BTS, constructs a practical statistical distribution curve for a power ratio of signal to interference, compares the practical distribution curve with the theoretical distribution curve pre-constructed based upon the parameter condition of a BTS, and determines the quality of a reverse link based upon the difference between the distribution curves.

Abstract: An object is to make efficient pre-reading possible even in receivers having little memory for receiving. A CPU 147 acquires data size in each module by referring module control information for a received DII, (step S39). The data sizes of the modules are compared with the remaining memory in a RAM 144 (step S45), and modules smaller than the remaining memory are pre-read into the RAM 144 (step S47). When a pre-read flag is not on, then no pre-reading is done even when a module is smaller than the remaining memory. Thus data that are updated from time to time can be excluded from being subject to pre-reading.

Abstract: The illustrated embodiment of the present invention provides an efficient means of obtaining traffic information selectively tailored to a motor vehicle's current location. It allows additional detail to be transmitted to the occupant of a motor vehicle as a result of a smaller geographic area being reported. The use of the current motor vehicle location allows the present invention to omit extraneous information that is of limited interest to the occupant of the motor vehicle because it is outside the intended path of travel. The illustrated embodiment also allows for a dynamic real time updating of traffic conditions as they change over the course of time.
