Abstract

PURPOSE: To reduce power consumption without deteriorating a call termination rate by lengthening the timing of a receiving part power supply ON/OFF control signal when the remaining amount of a battery is small.
CONSTITUTION: When the remaining amount detected by a battery remaining amount detecting part 31 becomes below a prescribed value, a remaining amount control part 31 selects a pulse 20 as the output of a frequency divider circuit 2. When the pulse 20 is selected, battery consumption per unit time is reduced to half as clearly as from the comparison of square waves 21, 22, and the usable time of the battery can be lengthened. Thus, the mean power consumption can be reduced without deteriorating the call termination rate to its own station. In the case that the frequency of a terminating call is low, or when the speed of response time is not requested, the remaining amount of the battery is detected, and if the remaining amount is small, the mean power consumption can be reduced without deteriorating the call termination rate by lengthening the timing of the receiving part power supply ON/OFF control signal. Besides, by lengthening the timing of the receiving part power supply ON/OFF control signal only for a definite period of time, the mean power consumption can be reduced.

【0001】 [0001]

【産業上の利用分野】この発明は、移動体通信における間欠受信装置に関するものである。 BACKGROUND OF THE INVENTION This invention relates to an intermittent receiving apparatus in a mobile communication.

【0002】 [0002]

【従来の技術】移動体通信では、複数の移動局が共通の基地局を介して交換電話回線に接続する。 BACKGROUND ART In mobile communication, a plurality of mobile stations connects to the switched telephone via a common base station. 基地局から、 From the base station,
待受受信モードにある移動局へ着呼があったことを通知するには、特定の搬送波周波数を用い、異なる移動局に対しては時分割方式によって互いに異なる時点で通知を行っている。 To notify that an incoming call to a mobile station in a standby receive mode, using a specific carrier frequency, it is carried out notification at different times from each other by time division system for different mobile stations. 従って、各移動局では電池の消耗を軽減させるため自局に通知があるタイミングだけ受信部に電源を接続するような制御を行う。 Accordingly, it performs control so as to connect the power source to only the receiver timing is notified to the mobile station in order to save battery power in the mobile station. このような動作をする受信装置を間欠受信装置という。 The receiver for such an operation that an intermittent receiving apparatus.

【0003】図8は、科学新聞社「ディジタル移動通信」(平成4年9月)の第190頁に記載されている従来の間欠受信方式のタイミング図である。 [0003] Figure 8 is a timing diagram of a conventional intermittent receiving method that is described in the 190 pages of scientific newspaper "Digital Mobile Communication" (September 1992). 図において、 In the figure,
15は基地局から周期的に繰り返して連続送出されている信号を示し、その内の16は基地局から所属する全ての移動局に対し一斉に制御信号を放送するための放送チャネル、17は第1〜第m群の各群に属する移動局に時分割で個別に着呼の通知を出す個別チャネル、18は第n群に対する個別チャネルである。 15 shows a signal that is continuously sent out periodically and repeatedly from the base station, the broadcast channel for 16 of them to broadcast simultaneously control signal to all the mobile stations belonging from the base station, the 17 first 1 dedicated channel out individually incoming call notification in a time divided mobile stations belonging to each group of the m groups, 18 is dedicated channel for the first n group. 第n群に属するどの移動局宛であるかを表すには、個別チャネル18の中に宛先のID(識別信号)を入れて区別する。 To represent whether any mobile station addressed belonging to the n groups, distinguishing put destination ID (identification signal) in the individual channels 18. 個別チャネル18の繰り返し周期はTであり、その継続時間はDであるとすれば、受信電源のオン・オフのタイミングは、 Repetition period of the dedicated channel 18 is T, if its duration is D, the timing of the on and off states of the received power,
符号21で示すように、周期Tで個別チャネル18に同期し、その継続時間は>Dとすればよい。 As indicated at 21, synchronized to the individual channel 18 at period T, the duration may be set to> D. 着呼信号が検出され、これに応答した移動局は基地局から指定された電波を用いて基地局経由で相手局と交話を行う。 Incoming call signal is detected, it performs the other station and 交話 via the base station using radio waves mobile station in response is specified by the base station to it.

【0004】図7は従来の間欠受信装置の構成を示すブロック図であり、図において、5はスイッチ回路、6は受信部、7は電源部、8は空中線、9は受信機出力探端子、10は制御回路である。 [0004] Figure 7 is a block diagram showing a configuration of a conventional intermittent receiving apparatus, in the figure, the switch circuit 5, the receiving unit 6, 7 is a power supply unit, the antenna, the receiver output probe terminal 9 8, 10 is a control circuit. 制御回路10によってスイッチ回路5を制御し、図8の波形21に示す時間の間、 Controls the switch circuit 5 by the control circuit 10, during the time indicated by the waveform 21 in FIG. 8,
受信部6に電源部7からの電源を接続する。 Connect the power from the power supply unit 7 to the receiving section 6. ところで制御回路10は、初期状態においては個別チャネル18が存在する時点を知ることができない。 Meanwhile control circuit 10 can not know when there is a dedicated channel 18 in the initial state. 従って、この場合はスイッチ回路5を制御し、受信部6に常時電源が供給されるようにし、放送チャネル16に含まれる同期信号を検出し、検出した同期信号から個別チャネル18の存在位置を決定し、図8に符号19で示すタイミング信号Tを発生する。 Therefore, in this case controls the switching circuit 5, so the power constantly supplied to the reception unit 6 detects a synchronizing signal included in the broadcast channel 16, determine the location of the individual from the detected synchronization signal channel 18 and, it generates a timing signal T shown by reference numeral 19 in FIG. 8. 一度タイミング信号T19を発生させた後は、個別チャネル18内の同期信号を利用して同期を維持する。 After once to generate a timing signal T19, to maintain synchronization by using the synchronization signal in the individual channels 18.

【0005】ところで、図8から明らかなように、Dが一定の場合はTが大きいほど電池の消耗を節約できる。 By the way, as is clear from FIG. 8, if D is constant can be saved consumption of the battery as T is large.
一方、Tが大きくなるほど、着呼の発生からその処理完了までの時間が長くなる。 On the other hand, T increases, the time from the occurrence of an incoming call to the process completion longer. また、受信電界強度が小さくなると、個別チャネル18の受信漏れが発生するので着呼処理を促進するためにTを小さくする必要がある。 Further, when the received field strength is reduced, it is necessary to reduce the T to facilitate call processing since reception failure of the individual channels 18 is generated. また、電池の残量が小さいときはTを大きくして電池の消耗を節約し、通信量の少ないときは着呼処理の遅れがあっても大きな支障が起こらないので、Tを大きくして電池を節約する等、状況に応じてTの値を可変できれば電池をより有効に利用できることになる。 Further, when the remaining amount of the battery is small, by increasing the T save battery power, because does not occur a large problem even if there is delay in the incoming call processing when less traffic, to increase the T cell etc. to save, the more effective use can be a battery if the variable value of T depending on the situation.

【0006】 [0006]

【0021】分周回路2の分周比Nは、任意の自然数を設定することができるが、実際問題としてはN=1又はN=2のうちの何れかに設定される場合が多い。 The division ratio of the frequency divider circuit 2 N is capable of setting an arbitrary natural number, as a practical matter is often set to one of N = 1 or N = 2. 従って、分周回路2の出力は、分周回路2の入力であるパルス19をそのまま出力するか、2分周したパルス20を出力することになる。 Thus, the output of the frequency dividing circuit 2, or outputs a pulse 19 which is the input of the frequency divider circuit 2 as it is, and outputs a 1/2 frequency pulse 20. そして、パルス19を出力するか、パルス20を出力するかは、制御部3からの信号によって制御される。 Then, it outputs the pulse 19, or outputs a pulse 20 is controlled by a signal from the control unit 3. 制御部3については後節で説明する。 For the control unit 3 will be described in a later section. 分周回路2の出力は、ゲート部4によってパルス幅Dの矩形波パルスの21または22に変換され、この矩形波パルスによりスイッチ回路5が制御される。 The output of the frequency dividing circuit 2 is converted by the gate unit 4 to 21 or 22 of the rectangular pulse of pulse width D, the switching circuit 5 is controlled by the rectangular wave pulse.

In the figure, the same reference numerals as in FIG. 3 denote the same or corresponding parts, 33 denotes a change-over switch constituting the control unit 3. 移動局の操作者が機に応じて切換スイッチ33を切り換えてNの値を制御し、操作者が移動局の応答が少しは遅れても支障ないと判断した時は、分周比Nを大きくして電池の使用を抑制する構成としている。 The operator of the mobile station switches the changeover switch 33 depending on the machine to control the value of N, when the operator determines that there is no problem even if a little response delay of the mobile station, increasing the frequency division ratio N It is to suppress configure the use of batteries and.

【0025】実施例4.
