Field of the Invention The present invention relates to a discontinuous reception system effective for extending a time (standby time) in which a mobile phone is operated by a battery, such as a pager, a cordless phone, a mobile phone, etc., for waiting for an incoming call. ..

秒間に１回で良いことになる。In general, the intermittent reception cycle of a portable radio is determined by the connection quality of the mobile station, for example, the maximum connection delay time. The main parameters that determine the maximum connection delay time are (1) the intermittent reception cycle and (2) the ratio at which the signal is not accurately received in the reception cycle (hereinafter referred to as the non-reception rate). For example, if the probability that a signal is correctly received during one reception cycle is 0.83, the non-reception rate after four receptions is (1-0.83) 4 ≈8.4 × 10 -4. .. When the maximum connection delay time is 4 seconds and the non-reception rate is defined as 10 −3 , in this example, intermittent reception must be performed once per second. However, when the signal reception rate is 0.97, the non-reception rate similar to the above condition can be obtained by two receptions ((1-0.97) 2 = 9 × 10 -4 ), so maximum connection is possible. If the delay time is 4 seconds, the intermittent reception cycle is doubled to 2
It only needs to be done once a second.

ている。However, normally, the intermittent reception cycle of each portable radio is uniformly defined within the zone covered by at least one radio base station. In that case, the intermittent reception cycle is determined so that the non-reception rate in the portable wireless device with the worst reception quality (for example, the portable wireless device located at the edge of the wireless zone) is equal to or less than the predetermined value. As a result, a portable wireless device with good reception quality receives signals more frequently than necessary and wastes power.
