PURPOSE:To correct the carrier frequency of a service channel assigned to a mobile station itself on a basis of the frequency of pilot signals by receiving pilot signals at every prescribed time. CONSTITUTION:Mobile station 5 switches a channel from its down channel to the pilot channel at every prescribed time and receives pilot signals from base station 1 and stores the frequency of them. After that, the channel is switched from the pilot channel to its own channel to correct the carrier frequency on a basis of the stored frequency. At a service time, switching to the pilot channel is stopped, and service is performed while holding the frequency corrected on a basis of the stored frequency. |
