  • only one of the instructions to register information of the first base station apparatus 102 or the second base station apparatus 103 may be performed. That is, while the information of the third base station apparatus 111 is registered in the first base station apparatus 102 or the second base station apparatus 103, the first base station apparatus 102 or the third base station apparatus 111 is registered. The information of the two base station apparatuses 103 may not be registered.
  • the base station apparatus (the second base station apparatus 103 and the third base station apparatus 111 in the example of FIG. 7) that received the instruction adds information to the adjacent base station list (adjacent cell list) according to the instruction. , Update the list (S710). Then, the base station apparatus establishes an inter-base station communication link with the newly added base station apparatus according to the update. As a result, the adjacent base station relationship in consideration of relaying by the relay device is established, and, for example, the third base station device 111 can receive data transfer quickly from the second base station device 103.
  • the third base station apparatus 111 obtains it in S705 in advance. It is possible to add the information of the base station apparatus obtained above to the neighboring base station list (the neighboring cell list). In this case, the control device may not transmit the above-described instruction to the third base station device 111.
  • the control device is included in the third base station device 111. For this reason, communication between the third base station apparatus 111 and the control apparatus as in S707 and S709 in FIG. 7 is performed internally via a bus or the like in the third base station apparatus 111. .
  • the determination in S708 is to be executed inside the third base station apparatus 111 (S801). Then, an instruction to add information to the adjacent base station list (adjacent cell list) according to the determination result of S801 is transmitted only to the second base station apparatus 103 (S802). In this way, even when the control apparatus is present inside the second base station apparatus 103, the process is executed as in FIG. Also in this processing example, the adjacent base station relationship in consideration of relaying by the relay device is established, and for example, the third base station device 111 can receive data transfer from the second base station device 103 promptly. It becomes possible.

Abstract

La présente invention concerne un dispositif de commande qui ordonne à un premier dispositif de station de base ou à un deuxième dispositif de station de base d'enregistrer des informations concernant un troisième dispositif de station de base en tant qu'informations concernant un dispositif de station de base adjacent, et ordonne au troisième dispositif de station de base d'enregistrer des informations concernant le premier ou le deuxième dispositif de station de base en tant qu'informations concernant une station de base adjacente, sur la base d'au moins un commutateur, par un équipement terminal qui est en communication sans fil en parallèle avec les premier et deuxième dispositifs de station de base tout en étant sous le contrôle du premier dispositif de station de base parmi la pluralité de dispositifs de station de base, entre une connexion avec le deuxième dispositif de station de base et une connexion par l'intermédiaire d'un dispositif de relais avec le troisième dispositif de station de base.
