公知である。(b) Conventional technology Conventionally, a wireless telephone device consists of a base unit connected to a telephone line and a slave unit connected to the base unit via a wireless line.
It is publicly known.
此種無線電話装置における待ち受け時のチャンネル制御
動作は、一般に以下のいずれかの方法にて達成される。Channel control operations during standby in this type of radio telephone device are generally achieved by one of the following methods.

（ハ）発明が解決しようとする課題
上記従来の各方式では、以下のような問題を生じるもの
であった。a. Single-channel method A method in which the receiving channel is fixed and reception operations on that channel and operations in which the power to the receiving section is cut off are performed intermittently.A method in which a multi-channel method uses multiple reception channels and reception operations on each channel are performed. (c) Problems to be Solved by the Invention Each of the conventional methods described above has the following problems.
ａ、シングルチャンネル方式
固定のチャンネルでしか受信動作を行わないので、受信
時間が短く且つ受信部の電源をオフしている期間が長く
なるため、子機の電源となる電池の消耗が少なくなり、
待ち受け時間の長期化を計ることができるが、１チヤン
ネルの受信しか行わないため、当該チャンネルに妨害波
（例えば、他の無線電話装置による当該チャンネルの使
用やＯＡ機器からの不要電波）が生じると、通信できな
くなると云う問題を生じる。a. Since the reception operation is performed only on the fixed channel of the single channel system, the reception time is short and the period when the receiver is turned off is longer, which reduces the consumption of the battery that powers the handset,
Although it is possible to lengthen the standby time, since only one channel is received, interference waves (for example, use of the channel by other wireless telephone devices or unnecessary radio waves from OA equipment) may occur on that channel. , the problem arises that communication becomes impossible.
ｂ、マルチチャンネル方式
複数の受信チャンネルの状態を判定してチャンネル制御

ャンネル全ての受信状態を検出しなければならないため
、受信動作に費やす時間が大となり、子機の待ち受け時
間が短くなるという問題を有している。b. Multi-channel system Channel control is performed by determining the status of multiple receiving channels, so even if one channel becomes unusable due to interference waves as described above, communication can be performed using other channels. However, since it is necessary to detect the reception status of all the plurality of channels when receiving a channel, there is a problem that a large amount of time is spent on the reception operation, and the standby time of the handset is shortened.
