PURPOSE:To improve the frequency utilizing efficiency in the cellular mobile communication system in which a same frequency is repeatedly and periodically in use. CONSTITUTION:When the frequency hopping is implemented in the mobile communication system employing the frequency hopping system, the communication is implemented in the hopping pattern in which the simultaneous use of the same frequency as that of an adjacent cell is allowed in a center region 3 of a radio zone 1. On the other hand, the communication is implemented in the hopping pattern inhibiting the use of the same frequency as that of an adjacent cell in a peripheral region of the radio zone. When both regions are moved or the radio zones are moved, the hopping pattern is switched to implement the communication. |
