Communication system

A communication system comprising:

• a plurality of access point apparatus arranged along a predetermined route,
• a plurality of station apparatus arranged on a mobile body adapted to move along the predetermined route and
• an intra-mobile-body communication network for connecting the plurality of station apparatus,
• the station apparatus being adapted to become belonging to one of the access point apparatus by wireless communication so as to be connected to a network by way of the access point apparatus,
• the station apparatus located front-most in the moving direction of the mobile body being adapted to transmit the information acquired at the time of retrieving an access point apparatus to which the station apparatus located front-most in the moving direction of the mobile body is adapted to belong, to the station apparatus other than the station apparatus located front-most in the moving direction of the mobile body by way of the intra-mobile-body communication network.

A communication system comprising:

• a plurality of access point apparatus arranged along a predetermined route,
• a plurality of station apparatus arranged on a mobile body adapted to move along the predetermined route and
• an intra-mobile-body communication network for connecting the plurality of station apparatus,
• the station apparatus being adapted to become belonging to one of the access point apparatus so as to be connected to a network by way of the access point apparatus,
• each of the station apparatus having storage means for storing information showing the access point apparatus to which it used to belong to,
• the station apparatus located front-most in the moving direction of the mobile body being adapted to store the information it acquires at the time of retrieving an access point apparatus to be belonging to in the storage means by way of the intra-mobile-body communication network,
• the station apparatus other than the station apparatus located front-most in the moving direction of the mobile body being adapted to refer to the information stored by the front-most station apparatus in the storage means prior to retrieving an access point apparatus to be belonging to.

A communication system comprising:

• a plurality of access point apparatus arranged along a predetermined route,
• a plurality of station apparatus arranged on a plurality of mobile bodies adapted to move in the same direction along the predetermined route, each of the mobile bodies having at least a station apparatus arranged thereon and
• an inter-mobile-body communication network for connecting the plurality of station apparatus,
• the station apparatus being adapted to become belonging to one of the access point apparatus by wireless communication so as to be connected to a network by way of the access point apparatus,
• each of the station apparatus having means for judging if the mobile body where the own apparatus is arranged is located front-most in the moving direction of the mobile body or not,
• the station apparatus arranged on the mobile body located front-most in the moving direction being adapted to notify the station apparatus arranged in the mobile bodies not located front-most with the information acquired at the time of retrieving an access point apparatus to be belonging to by way of the intra-mobile-body communication network.
