で移動機が移動する限りは位置登録を不要にすることを
主要な特徴としている。[Function] According to the present invention, a mobile device aggregates the history of its location over a certain period of time, uses the learning effect thereof to create a list of areas with a high probability of being in each time period, and uses this list with the mobile device. The network shares this list, and from this shared list, an area with a high probability of being located by the mobile device is derived according to a predetermined algorithm, and as long as the mobile device moves within this high probability area, location registration is not required. Its main feature is to
ただし、在圏高確率エリアではないエリアへ移動があっ
たときには、位置登録を行なうとともに、着呼の際は、
この位置登録結果を優先してネットワークから呼び出し
を行なう。However, if you move to an area that is not a high probability area, you will be required to register your location and receive a call.
A call is made from the network with priority given to this location registration result.
従来技術とは、学習により移動機の在圏確率の高いエリ
アのリストを作成すること、このリストから導かれる在
圏高確率エリアとは異なるエリアへ移動したときだけ位
置登録が行なわれることが異なる。The difference from the conventional technology is that a list of areas with a high probability of the mobile device being located is created through learning, and location registration is performed only when moving to an area different from the high probability area of the mobile device derived from this list. .
本発明の一実施例を第１図に示す。この図では、１〜５
で示す５つのエリア（Ａ −Ｅ ）に基地局６〜１０が
あり、交換局（Ｆ）１２に接続されている。An embodiment of the present invention is shown in FIG. In this figure, 1 to 5
There are base stations 6 to 10 in five areas (A-E) shown by and connected to an exchange (F) 12.
移動ｆｉ（Ｚ）１１は、各基地局が送出している信号を
受信し、基地局に固有なコードを抽出することにより、
自分の在圏エリアを知ることができる。The mobile fi(Z) 11 receives the signals sent by each base station and extracts the code unique to the base station.
You can know your area.
このようにして得られる時間ごとの在圏エリアについて
統計処理を行ない、在圏確率が高い順番にエリア名を並
べたリストを作成する。リストの一例を第２図に示す、
同リストでは時刻Ｏ〜２では、エリア （Ａ）に存在す
る確率が最も高く、４番目はエリア （Ｅ）であること
を示している。Statistical processing is performed on the area in which the user resides for each time obtained in this way, and a list is created in which area names are arranged in descending order of probability of being in the area. An example of the list is shown in Figure 2.
The same list shows that from time O to 2, the probability of being in area (A) is highest, and the fourth place is area (E).
このような順位は、時間的に変化するので、各時間ごと
のリストを作る。このリストは例えば１力月ごとという
ように、移動機ごとに適当な期間で更新する。なお、第
２図に示すリストでは時開を区切る時点は、２時間とし
たが、これは等間隔である必要はなく、むしろ移動機の
使用者が一定エリアに滞在する時間中は、区切り時点を
設けるのを避けて、その使用者の動きのバタンに合わせ
て可変することが望ましい。Since these rankings change over time, a list is created for each time. This list is updated at appropriate intervals for each mobile device, such as once a month. Note that in the list shown in Figure 2, the time periods are divided into two hours, but these do not have to be at equal intervals; rather, during the time when the mobile device user stays in a certain area, the time periods are divided into two hours. It is desirable to avoid the provision of a shock absorber and make it variable according to the user's movements.
また、以上の説明では、移動機側でリストを作成する場
合を説明したが、基地局側でリストを作成・更新しても
よい。ただし、この場合には移動機側から各時刻におけ
る現在地の情報を通知する必要がある。Further, in the above description, a case has been described in which a list is created on the mobile device side, but the list may also be created and updated on the base station side. However, in this case, it is necessary for the mobile device to notify the current location information at each time.
以上のようにして作成したリストを交換局（Ｆ）１２に
報知し、交換局（Ｆ）１２はそのリストをメモリに蓄積
する。移動ｆｆ１（Ｚ）１１と交換局（Ｆ）１２のリス
トの内容は一致している。あらかじめ定めらｎたアルゴ
リズムに従って、この共有リストから在圏高確率エリア
が導出される。The list created as described above is notified to the exchange (F) 12, and the exchange (F) 12 stores the list in its memory. The contents of the lists of the mobile ff1 (Z) 11 and the exchange (F) 12 match. A high probability area is derived from this shared list according to a predetermined algorithm.
この在圏高確率エリアの導出については、現時点を含む
時間帯にリストアツブされているエリアと次の時間帯に
リストアツブされているエリアの和集合エリアを在圏高
確率エリアとし、さらに両エリアの積集合に対してより
高い順位を与える方法などが考えられる。In order to derive this area with a high probability of being in the area, the sum of the area restored in the time period including the current time and the area restored in the next time period is defined as the area with a high probability of being in the area, and then the product of both areas is One possible method is to give a higher rank to the set.
例えば時刻Ｏ〜２では、この時刻の次の時刻２〜４の在
圏エリアとの和集合のエリア （Ａ＞、エリア（Ｂ）、
エリア（Ｃ）、エリア（Ｄ）、およびエリア（Ｅ）を在
圏高確率エリアとしたり、それらの積集合のエリア（Ａ
）、エリア（Ｂ）およびエリア （Ｃ）により高い順位
を与えることが考えられる。For example, at time O~2, the area (A>, area (B),
Area (C), area (D), and area (E) can be set as areas with high probability of being in the area, or the area (A
), area (B), and area (C) may be given higher rankings.
この在圏高確率エリアは、移動機側で導出しようとネッ
トワーク側で導出しようと同一の結果となる。This high probability area of coverage will give the same result whether it is derived on the mobile device side or on the network side.
従って、移動ｆｉ （Ｚ） １１が基地局からの制御信
号を受信して、その基地局固有のコードを検出した結果
、在圏高確率エリアに在圏しているときには、位置登録
を行なう必要がない。Therefore, when the mobile fi (Z) 11 receives a control signal from a base station and detects a code unique to that base station, it is necessary to perform location registration when the mobile fi (Z) 11 is located in a high probability area. do not have.
例えば、第２図のリストをそのまま在圏高確率エリアと
して用いた場合には、時刻２〜４において、エリア（Ａ
）から、エリア（Ｂ）やエリア（Ｃ）やエリア（Ｄ）に
移動しても位置登録は行なわれない。For example, if the list in Figure 2 is used as it is as the high probability area, at times 2 to 4, the area (A
) to area (B), area (C), or area (D), location registration is not performed.
ただし、エリア（Ｅ）に移動したときには、このエリア
（Ｅ）は在圏高確率エリアではないので位置登録が行な
われる。そこから、また在圏高確率エリアに戻ってきた
ときは、その戻ってきたエリアで再度位置登録を行なう
。エリア（Ｅ）での位置登録を消去するためである。こ
れ以降、この高確率エリア内で移動する限り、位置登録
は不要である。However, when the user moves to area (E), location registration is performed because area (E) is not a high probability area. From there, when you return to a high probability area, you will register your location again in the area you returned to. This is to erase the location registration in area (E). From now on, as long as you move within this high probability area, location registration is not necessary.
以上の説明では、第２図に示すリストのエリアをその時
間帯の在圏高確率エリアとしたが、実際には第２図に示
すリストのように規則正しく、特定時刻にエリアを移動
するわけではなく、その移動タイミングは日々に変動す
る。In the above explanation, the areas in the list shown in Figure 2 are assumed to be areas with a high probability of being in that time period, but in reality, areas do not move regularly at specific times as shown in the list shown in Figure 2. The timing of their movements varies daily.
従って、適当な期間ごとにリストを更新する必要がある
のである。この更新期間は加入者ごとに、また移動パタ
ーンに応じて適宜変化させればよい。例えば、位置登録
回数が一定以上になったらリストを更新するようにして
も良い。Therefore, it is necessary to update the list at appropriate intervals. This update period may be changed as appropriate for each subscriber and depending on the movement pattern. For example, the list may be updated when the number of location registrations exceeds a certain value.
次に、着信の際にネットワークから移動機（Ｚ）１１を
呼び出すときは、まず、在圏高確率エリア外での位置登
録の有無を調べる。登録されていればそのエリアで呼び
出しを行なう。在圏高確率エリア外での位置登録が行な
われていなければ、在圏高確率エリアに対して呼び出し
を行なう。Next, when calling the mobile device (Z) 11 from the network when receiving a call, it is first checked to see if the location is registered outside the high probability area. If it is registered, the call will be made in that area. If the location has not been registered outside the high probability area, a call is made to the high probability area.
一つの方法は、確率の高い方のエリアから順に呼び出す
方法である。その場合には、確率の低い方のエリアに移
動機がいる場合には呼び出しに遅延が生じる。この遅延
が問題になる場合には、その時間帯のリスト上のエリア
で同時に呼び出しを行なう。One method is to call areas in order of probability. In that case, if the mobile device is in the area with lower probability, there will be a delay in calling. If this delay becomes a problem, call the areas on the list for that time period at the same time.
以上のようにして、位置登録が行なわれるので、位置登
録の処理量が大幅に低減される。Since location registration is performed in the manner described above, the amount of processing for location registration is significantly reduced.
以上説明したように、位置登録処理が低減されるので、
以下のような効果がある。As explained above, since the location registration process is reduced,
It has the following effects.
（ｉ）ネットワーク側の処理が簡易になり、より多くの
基地局を設置することができる。(i) Processing on the network side becomes simpler and more base stations can be installed.
（ｉｉ）基地局が多くできるので、利便性が増す。(ii) Convenience increases because more base stations can be installed.
（ｉｉｉ）基地局が多くできるので、よりたくさんの移
動機を収容できる。(iii) Since more base stations can be built, more mobile stations can be accommodated.
