実施形態のスキャタネットの構成図の一例である。It is an example of the block diagram of the scatter net of embodiment.

以下、本発明の実施の一形態について詳細に説明する。  Hereinafter, an embodiment of the present invention will be described in detail.

図1は実施形態のスキャタネットの構成図の一例である。例えば、スキャタネットは、ピコネット(図1の点線内)を構築するBT(ブルートゥース:登録商標)のマスタM、ピコネットに参加する少なくとも1つ以上のBTのスレーブS、BTパケットを送受信する図示させていない情報処理部、および各ポートがマスタMとスレーブSと情報処理部に繋がり、BTパケットを受信して他のポートへ転送するスイッチ部Swを備えるBTユニット1と、スレーブSを備え、該スレーブSを介してBTパケットを送受信するBTユニット1に接続する周辺機器をなすBTユニット2と、スレーブSを備え、該スレーブSを介してBTパケットを送受信するスキャタネットの端末をなすBTユニット3と、から構成され、BTユニット1が複数存在し、1つのピコネットに少なくとも1つ以上のスレーブSが参加可能であり、BTユニット1のスレーブSが他のBTユニット1のマスタMが構築したピコネットに参加してピコネット内通信を行うことで、ピコネット同士が網目構造に接続されたスキャタネットを構築し、BTユニット2、3のスレーブSが何れか1つのピコネットに参加してピコネット内通信を行いピコネット内で複数のBTユニット1〜3が共存する。また、三つのスレーブSと一つのスイッチ部Swで構成されるBTユニット3を設けてもよい。  FIG. 1 is an example of a configuration diagram of the scatternet of the embodiment. For example, the scatternet transmits and receives a BT (Bluetooth: registered trademark) master M that constructs a piconet (inside the dotted line in FIG. 1), at least one BT slave S that participates in the piconet, and transmits and receives BT packets. An information processing unit that is not connected to each other, and each port is connected to the master M, the slave S, and the information processing unit, and includes a switch unit Sw that receives a BT packet and transfers it to another port, and a slave S, A BT unit 2 that is a peripheral device connected to the BT unit 1 that transmits and receives BT packets via the slave S, and a scatter unit that includes the slave S and that serves as a scatternet terminal that transmits and receives BT packets via the slave S 3 and a plurality of BT units 1 exist, and at least one slave unit is included in one piconet. S can participate, and the slave S of the BT unit 1 participates in the piconet constructed by the master M of the other BT unit 1 and performs communication within the piconet, whereby the piconet is connected to the network structure. And the slaves S of the BT units 2 and 3 participate in any one piconet to perform intra-piconet communication, and a plurality of BT units 1 to 3 coexist in the piconet. Moreover, you may provide the BT unit 3 comprised by the three slaves S and the one switch part Sw.

BTユニット1〜3などの装置は、CPU、ROM、RAMなどを有するコンピュータ部を備えている。BTユニット1のマスタMとスレーブSは、無線送受信部を共有している。  Devices such as the BT units 1 to 3 include a computer unit having a CPU, a ROM, a RAM, and the like. The master M and the slave S of the BT unit 1 share a wireless transmission / reception unit.

スイッチ部Swは、L3スイッチを構成し、二つ又は三つのピコネットの経路管理をすべて行うFDB(Forwarding DataBase)などを備え、各ポートから受信したBTパケットを夫々のFDBなどに照らして他のポートへ転送することとなる。また、二つ又は三つのピコネットの中継点を構成し、該ピコネットから受信した各BTパケットをFDBなどに照らして、転送先となるBTユニット1、3を判定し、該BTユニット1、3を該BTパケットの転送先に指定して該BTユニット1、3側のポートに転送し、BTパケットの転送を受けたマスタMまたはスレーブSがBTパケットを該BTユニット1、3に送信することとなる。  The switch unit Sw is configured as an L3 switch and includes an FDB (Forwarding DataBase) that performs all path management of two or three piconets, and other ports are compared with other ports in view of BT packets received from each port. Will be transferred to. Further, the relay point of two or three piconets is configured, and each BT packet received from the piconet is checked against the FDB or the like to determine the BT unit 1 or 3 as a transfer destination. Designating the transfer destination of the BT packet, transferring it to the port on the BT unit 1, 3 side, and the master M or slave S receiving the transfer of the BT packet sending the BT packet to the BT unit 1, 3; Become.

BTユニット1は、自己の識別情報などをピコネット識別情報とし、該ピコネット識別情報および自己のスレーブSが参加したピコネットのピコネット識別情報を含むビーコンを自己のマスタMから他のBTユニット1などに向けてブロードキャスト送信させるとともに、他のBTユニット1から受信したビーコンを基に自己のスレーブSを参加させるピコネットを選んでそこに参加させて、自己を含む3つのBTユニット1の環が他の環と連環する様に制御する。  The BT unit 1 uses its own identification information as piconet identification information, and directs the beacon including the piconet identification information and the piconet identification information of the piconet to which the slave S participates from the master M to another BT unit 1 or the like. Broadcast transmission, and select a piconet to participate in its own slave S based on the beacon received from the other BT unit 1 and join it there, and the ring of the three BT units 1 including itself is connected to the other ring. Control to link.

具体的には、BTユニット1aの場合に、受信したビーコンを基に一方のスレーブSが、自己を含む3つのBTユニット1の環が他の環と連環をなす条件に該当するBTユニット1bが構築したピコネットを選んで参加し、自己を含む3つのBTユニット1a、1b、1cを環にさせるとともに、受信したビーコンを基に他方のスレーブSが自己を含む3つのBTユニット1が、連環をなす条件に該当するBTユニット1dが構築したピコネットを選んで参加し、自己を含む3つのBTユニット1a、1b、1dを連環させることとなる。ここで、BTユニット1は、自己を含む3つのBTユニット1が連環を構成する適当なピコネットが見当たらない場合に、自己が接続していない他のBTユニット1が構築した任意のピコネットを見付けてそこに参加することとなる。Specifically, in the case of the BT unit 1a, one slave S is based on the received beacon and the BT unit 1b corresponding to the condition in which the ring of the three BT units 1 including itself is connected to the other ring Select and participate in the constructed piconet, and make the three BT units 1a, 1b, and 1c including the self into thering, and the other slave S based on the received beacon has the three BT units 1 including the self The piconet constructed by the BT unit 1d corresponding to the conditions to be formed is selected and participated, and the three BT units 1a, 1b, and 1d including the self are linked. Here, the BT unit 1 finds an arbitrary piconet constructed by another BT unit 1 to which the BT unit 1 that is not connected is not found when there is no suitable piconet in which the three BT units 1 including the self are connected. You will be there.

It is also possible to provide a means for the self to participate in another piconet so that the ring of the three BT units 1 including the self is connected to the other ring. The BT units 1 to 3 include a communication integrated circuit including a master M, a switch unit Sw, a slave S, and the like, and the master M, the switch unit Sw, the slave S, and the like are controlled by the communication integrated circuit, and the BT unit. It is good also as a structure which implement | achieves 1-3. Further, in order to prevent the piconet from standing up in the same area, each BT unit 1 may function as the BT unit 3 in accordance with the number of piconets in the same area.

However, the control program may be recorded on a storage medium readable by the computer unit. With such a configuration, when the program is read from the storage medium by the computer unit and the computer unit executes processing according to the read program, the same operations and effects as those of the devices of the above-described embodiment can be obtained.

ここで、記憶媒体とは、RAM、ROM等の半導体記憶媒体、FD、HDD等の磁気記憶型記憶媒体、CD、DVD、BD等の光学的読取方式記憶媒体、MO等の磁気記憶型/光学的読取方式記憶媒体であって、電子的、磁気的、光学的等の読み取り方法のいかんにかかわらず、コンピュータ部で読み取り可能な記憶媒体であれば、どのような記憶媒体であってもよい。  Here, the storage medium is a semiconductor storage medium such as RAM or ROM, a magnetic storage type storage medium such as FD or HDD, an optical reading type storage medium such as CD, DVD or BD, or a magnetic storage type / optical such as MO. Any storage medium can be used as long as it is a computer-readable storage medium regardless of electronic, magnetic, optical, or other reading methods.

また、インターネット、LAN等のネットワークシステムを介して制御プログラムをダウンロードし、インストールして実行するように構成することも可能である。  Further, the control program can be downloaded, installed and executed via a network system such as the Internet or a LAN.
