【発明の実施の形態】次に、本発明の実施の形態について図面を参照して説明する。 BEST MODE FOR CARRYING OUT THE INVENTION Next, a description with reference to the drawings, embodiments of the present invention.

【0010】図1を参照すると、本発明はその最良の実施の形態において、1または複数の固定通信局との間で間欠受信を行う移動体通信局が、着信を受ける受信部1 [0010] Referring to FIG. 1, the present invention is in the form of its best embodiment, the mobile communication station performs intermittent reception between one or more fixed communication stations, receiving unit 1 for receiving an incoming
と、各時間帯における着信履歴を更新する履歴更新部2 If, history update unit 2 for updating the call history in each time zone
と、着信履歴を記録するための履歴記録部3と、履歴更新部2が履歴記録部3に記録した情報に基づいて間欠受信の周期を決定する間欠受信周期決定部4と、間欠受信周期決定部4により決定された周期を固定通信局に伝える送信部5と、間欠受信周期決定部4により決定された周期に基づいて間欠受信を行う内部タイマ6および間欠受信実行部7と、を含む。 When, a history recording unit 3 for recording the received call history, an intermittent reception period determining unit 4 which history update unit 2 determines the cycle of the intermittent reception on the basis of the information recorded in the history recording unit 3, the intermittent reception period determining comprising a transmitting unit 5 for transmitting the period determined by the parts 4 to fixed communication station, an internal timer 6 and the discontinuous reception execution unit 7 for intermittent reception based on the period determined by the intermittent reception period determining unit 4, a. 履歴更新部2、履歴記録部 History update section 2, history recording unit
3、間欠受信周期決定部4、内部タイマ6および間欠受 3, the discontinuous reception period determining unit 4, the internal timer 6 and the intermittent receiving
信実行部7が間欠受信制御回路11を構成する Shin execution unit 7 constitute the intermittent reception control circuit 11.

【0011】ここで、固定通信局から移動通信局に向けて送信される制御用の信号は、基本フレーム(BFR) [0011] Here, the signal for control is transmitted to the mobile communication station from the fixed communication station, the base frame (BFR)
およびスーパーフレーム(SFR(=BFR×l:l= And the super-frame (SFR (= BFR × l: l =
整数))から構成されているが、この整数lの値を、移動体通信局側の過去の着信履歴によって決定するものとする。 Are constituted by an integer)), the value of this integer l, shall be determined by the past incoming call history of the mobile communication station. これにより、各個人毎に呼び出し量の多い時間帯から少ない時間帯にわたって連続的に間欠受信の周期を調整することができる。 Thus, it can be continuously adjusted period of intermittent reception for a small time period of more hours of call volume to each individual each.

【0012】すなわち、各個人の着信を受ける時間帯と頻度を毎日の各個人の傾向として捉え、その過去の着信履歴に基づいて各移動体通信局側自身の判断で間欠受信の周期を決定して間欠受信を行うことにより、移動体通信局のバッテリーをセーブする。 Namely, capture the time period and frequency for receiving the incoming of each individual as the tendency of each individual daily, to determine the period of the intermittent reception in the mobile communication station own judgment based on the past incoming call history by performing intermittent reception Te, saving the battery of the mobile communication station.

【0013】なお、各個人の着信履歴を記録する方法としては、移動体通信局が着信を受けた際に、着信のある度に移動体通信局側自身でその時間帯と着信の回数を記録し、前の日までの同一の時間帯の着信頻度を用いて記録を更新し、次の日における間欠受信の周期を作成するためのデータとして保存する。 [0013] As a method for recording the received call history of each individual, when the mobile communication station has received a call, records the number of time zones and terminating in the mobile communication station itself every time a call and to update the record with the reception frequency of the same time period before the day is stored as data for creating a cycle of the intermittent reception in the next day. このようにして、その日一日のデータが作成されると、その情報を固定通信局側に通知し、次の日の間欠受信の周期を固定通信局側が知ることにより、次の日の移動体通信局と固定通信局の間の間欠受信のタイミングを合わせることができる。 In this way, the data of the day the day is taken, the information notified to the fixed communication station, by the cycle of the intermittent reception of the next day fixed communication station knows the mobile the next day it is possible to match the timing of the intermittent reception with the communication station fixed communication station.

【0014】このときの間欠受信の周期は、スーパーフレーム(SFR)の整数lの値を調節することにより、 [0014] cycle of the intermittent reception at this time, by adjusting the value of the integer l superframe (SFR),
タイミングを変化させることができる。 It is possible to change the timing. また、各移動体通信局は、それぞれが更新した着信履歴のみをメモリに保存するため、その記録を読み出すだけで容易に次の日の間欠受信の周期のスケジュールを作成することができる。 Further, each mobile communication station, to store only the incoming call history, each updated in the memory, it is possible to create a schedule of the cycle of the intermittent reception simply connecting the next day reading the recording.

【0015】なお、前述した実施の形態では、過去の着信履歴に基づいて各移動体通信局側自身の判断で間欠受信の周期を決定しているが、他の実施の形態として、例えば固定通信局において各移動体通信局の運用形態(自動車等の車載機タイプ、可搬・携帯機タイプ、船舶タイプ等)と、各移動体通信局の過去の着信履歴を記録しておき、その日の終了時にこれらの記録された情報に基づいて各移動体通信局での間欠受信の周期を決定するようにしてもよい。 [0015] In the embodiment described above, but determines the cycle of the intermittent reception at the discretion of the mobile communication station itself based on the past incoming call history, as another embodiment, for example, a fixed communication operation mode of each mobile communication stations in the station (vehicle-mounted device type, such as an automobile, portable and mobile device type, ship type, etc.), keep a record of incoming call history of each mobile communication stations, the end of the day sometimes it may be determined the cycle of the intermittent reception in the mobile communication station on the basis of these recorded information.

【0019】次に、本発明の一実施例の動作を説明する。 [0019] Next, the operation of an embodiment of the present invention.

【0020】図2は、本発明の一実施例において固定通信局から移動体通信局に向けて送信される制御用の信号を模式的に示す図である。 [0020] FIG. 2 is a diagram schematically showing a signal for control is transmitted to the mobile communication station from the fixed communication station in one embodiment of the present invention.

【0021】図2に示すように、1または複数の固定通信局と複数の移動体通信局から構成される移動体通信ネットワークにおいては、固定通信局から移動体通信局に向けて、基本フレーム(BFR)およびスーパーフレーム(SFR(=BFR×l:l=整数))から構成される制御用の信号が送信される。 As shown in FIG. 2, 1 or, in more fixed mobile communication network and a communication station and a plurality of mobile communication stations, toward the mobile communication station from the fixed communication station, the base frame ( BFR) and superframe (SFR (= BFR × l: l = integer)) signal for controlling composed is transmitted.

【0022】図1に示した構成を備える各移動体通信局は、図2に示したスーパーフレーム(SFR)の整数l [0022] Each mobile communication station having the configuration shown in FIG. 1, an integer l superframe (SFR) shown in FIG. 2
の値を決定するために、以下のような手法をとる。 To determine the value, take the following technique.

【0023】まず、図3に示したように3時間単位に区切られた一日の時間帯において、その中のどの時間帯にどのぐらいの頻度で着信を受けるかを記録していく。 [0023] First of all, in the time period of the day that has been divided into 3 hours unit as shown in FIG. 3, continue to record or receive an incoming call at a frequency of about how any time zone in the.

【0024】最初に記録を行った日を第1日目として、 [0024] The day was first recorded as the first day,
日付が変わる瞬間に次の日の間欠受信の周期のスケジュールを決定し、次の日はこの決定された新たな周期のスケジュールに基づいて間欠受信を行う。 Date moment determines the schedule of the cycle of the intermittent reception of the next day to change, the next day the intermittent reception on the basis of the determined new cycle schedule.

【0025】日付が変わった次の日を第2日目とし、さらにこの第2日目にも第1日目と同様に、各時間帯毎に着信頻度を記録していくが、その際にはその都度平均値として記録を更新する。 [0025] The day of the following that date has changed to the second day, as well as further the first day to the second day, but continue to record the incoming frequency for each time zone, when the update record the average value each time. 平均値の計算方法としては、例えばある時間帯毎の着信頻度を日数で割る等の方法を採用することができる。 As a calculation method of the average value can be employed methods such as dividing the number of days the frequency of incoming call each time period there, for example. 第2日目の終わりには、その日に更新されたデータに基づいて次の日、すなわち第3日目の間欠受信の周期のスケジュールを決定する。 At the end of the second day, the next day, i.e., determines the schedule for the period of the third day of intermittent reception on the basis of the data updated on the day. このようにして、日数が更新される度に、以上の動作を繰り返す。 In this manner, every time the number of days is updated, repeating the above operation. 図4に、第1日目から順に着信頻度の平均値を計算していく場合の具体例を示す。 4 shows a specific example in which the first day continue to calculate the average value of the reception frequency in order.

【0026】図5は、本発明の一実施例における移動体通信局での間欠受信のための着信履歴の更新処理を説明するためのフローチャートである。 [0026] FIG. 5 is a flowchart for explaining the update processing of the incoming call history for the intermittent reception of the mobile communication station in an embodiment of the present invention.

【0027】図4および図5を参照すると、各移動体通信局は、着信がある度に(ステップ501)、該当する時間帯における着信回数を“1”だけ増加(インクリメント)する(ステップ502)。 Referring to FIGS. 4 and 5, each mobile communications station, incoming time (step 501) there is, the number of incoming calls in a time zone corresponding to "1" only increased (incremented) (step 502) .

【0028】ある時間帯についてステップ501および502の処理を繰り返した後、次の時間帯に移行した際に(ステップ503)、その移行前の時間帯について、 [0028] There was repeated the processes of steps 501 and 502 for the time period, when the subsequent time zone (step 503), the time period before the transition,
その日までの同一の時間帯の着信の回数の平均をとる(ステップ504)。 Averaging the number of the same time zone incoming until the day (step 504).

【0029】そして、この平均値をメモリの所定領域に記録した後(ステップ505)、次の着信があるまで待ち(ステップ506)、次の着信を受けたときには、日付が変わったか否かを判断し(ステップ507)、日付が変わるまで、すなわち1日の全ての時間帯について記録を更新するまで、前述したステップ502ないし50 [0029] Then, after recording the average value in a predetermined area of ​​the memory (step 505), waits until the next incoming (step 506), upon receiving the next incoming, it determines whether the date has changed (step 507), until the date changes, i.e. before updating the records for all times of the day, to not step 502 previously described 50
7の処理を繰り返す。 7 repeats processing of.

【0030】一方、ステップ507において、日付が変わったものと判断された場合には、次の日の間欠受信の周期のスケジュールを決定するとともに、固定通信局側にもその情報を通知し(ステップ508)、その日付が変わった次の日において、決定された新たな周期に基づいて固定通信局と移動体通信局の間で間欠受信を行う。 On the other hand, in step 507, if it is determined that the date has changed, as well as determining the schedule of the cycle of the intermittent reception of the next day, also notify the information to the fixed communication station (step 508), in the next day the date has changed, perform the intermittent reception between the mobile communication station and a fixed communication station based on the new period determined.

【0031】図6は、ステップ508において間欠受信の周期のスケジュールを決定する場合の具体例を示す図であり、第30日目の更新データに基づいて第31日目の間欠受信の周期を割り当てる場合の一例を示している。 [0031] FIG. 6 is a diagram showing a specific example of determining the schedule of the cycle of the intermittent reception in step 508, it assigns the first 31 day cycle of the intermittent reception on the basis of the 30th day of the update data It shows an example of a case.

【0032】図6を参照すると、まずスーパーフレーム(SFR)の長さを規定する整数lの上限値lmaxと下限値lminを決定し、次に、lmin<l<lma Referring to FIG 6, first, to determine the upper limit lmax and the lower limit value lmin integer l which defines the length of the superframe (SFR), then, lmin <l <lma
xの範囲で、ある時間帯の着信の回数の平均値に一致して移動体通信局の稼働率を下げるようなlの値を選択することにより、スーパーフレーム(SFR)の長さを決定する。 In the range of x, by selecting the values ​​of l, as consistent with the average number of times a certain time zone incoming lowering the operation rate of the mobile communication station, to determine the length of the superframe (SFR) . ここで、「稼働率を下げる」とは、通常の着信の待ち状態の間隔を“1”とした場合に、ある時間帯の着信の平均値の逆数倍に比例して着信の待ち状態(間欠受信)の周期を長くすることを意味する。 Here, "lowering the operating rate", when the spacing pending normal incoming "1", there waiting for an incoming call in proportion to the reciprocal of the mean value of the incoming time slot ( means that a longer period of intermittent reception). また、平均値がある値よりも大きい場合には間欠受信の周期lをlm Also, the period l of the intermittent reception is larger than a median value the value lm
inとし、平均値がある値よりも小さい場合には間欠受信の周期lをlmaxとする。 And in, and lmax the period l of the intermittent reception is smaller than a median value value.

【0033】すなわち、以上の関係を数式として表すと、次式(1)ないし(3)のようになる。 [0033] That is, when representing the above relationship as a formula, so to the following equation (1) to (3). l(t)=k・(1/m(t)) (a<m(t)<b) …(1) =lmin (m(t)<a) …(2) =lmax (m(t)>b) …(3) l (t) = k · (1 / m (t)) (a <m (t) <b) ... (1) = lmin (m (t) <a) ... (2) = lmax (m (t) > b) ... (3)

【0034】ただし、上式(1)ないし(3)において、tは時間帯番号、kは比例定数、m(t)は各時間帯毎の着信の回数の平均値、aはm(t)の下限値、b [0034] However, to the above equation (1) in (3), t is the time period number, k is a proportional constant, m (t) is the average value of the number of incoming in each time slot, a is m (t) lower limit value of, b
はm(t)の上限値を表す。 Represents the upper limit of m (t).

【0035】このように、上式(1)ないし(3)に基づいて整数lの値を制御して各時間帯毎の間欠受信の周期を決定すれば、過去の着信履歴を有効に活用したスケジュールを組むことができる。 [0035] Thus, by determining the period of the intermittent reception of the above equation (1) to each time slot by controlling the value of the integer l, based on (3), and effectively utilize the past incoming call history it can be scheduled.

【0036】 [0036]

【発明の効果】以上説明したように、本発明によれば、 As described in the foregoing, according to the present invention,
移動体通信における移動体通信局側での間欠受信において、着信頻度に応じて自動的に間欠受信の周期を変化させるため、移動体通信局側の電力を効率的に利用することができる。 In the intermittent reception in the mobile communication station in a mobile communication, automatically for changing the cycle of the intermittent reception, it is possible to utilize the power of the mobile communication station efficiently match the incoming rate.

【0037】また、本発明によれば、間欠受信の周期のスケジュールを決定する手法(アルゴリズム)として比較的簡易なものを採用することができるため、本発明を実際に実施する場合にきわめて簡単にシステムの構築を行うことができるという利点も有する。 Further, according to the present invention, it is possible to employ a relatively simple thing as a technique (algorithm) for determining the schedule of the cycle of the intermittent reception, very simply when actually implementing the present invention also has the advantage that it is possible to construct a system.
