PROBLEM TO BE SOLVED: To prevent the function from being damaged even when the energy consumption is lowered compared with a conventional mobile radio terminal equipment by using time delay depending on a reception level for retrial after the failure of synchronization to a radio channel provided with a prescribed reception level. SOLUTION: During the operation of a mobile radio terminal equipment 1, a program memory 2, a read/write memory 3 and a function unit 4 communicate with a control unit 5 and the control unit 5 controls all program sequences and execution in the mobile radio terminal equipment 1. Further, by a transceiver 6, converted quadrature components land Q are supplied through A/D conversion 8 to the function unit 4 for the post-processing. Also, the mobile radio terminal equipment 1 is provided with a synchronization unit 10 used for the synchronization of the transceiver 6 and the radio unit 4 on a prescribed radio channel. Then, through the prescribed radio channel, radio signals are transmitted from the reference station of a cellular mobile radio network every time. |
