  • Patent number: 7724690
    Abstract: To provide a transmission apparatus capable of setting the same control data to the entire child transmission apparatuses instantaneously at a time, thereby leading to improved maintenance operation and bringing about efficient maintenance and system stability. The transmission apparatus receives from a maintenance operator a designation of a parent apparatus having the control data set in advance. That control data is to be inherited to a child apparatus. The transmission apparatus determines whether any transmission apparatus has already been registered as parent apparatus in the child apparatus, and also determines whether the designated parent apparatus has already been registered as a child apparatus in the child apparatus. The transmission apparatus then requests the designated parent apparatus to transfer the control data in the designated parent apparatus to the child apparatus, when the designated parent apparatus is not registered in the child apparatus.

  • Patent number: 7643829
    Abstract: Time required for location registration is reduced and concentration of location update signals caused when a group moves is prevented. Each mobile node and a mobile router sends a location update request to a local location manager near to the area in which it exists, so that time required for location registration can be reduced, and it is possible to prevent pressure on wireless resources and temporary increase in communication traffic within a mobile network, which may be caused by concentration of location update signals when a group moves as in the case of a train with a lot of passengers having mobile nodes. Thereby, even if location registration is not correctly performed by a mobile router, which sends a location update request on behalf of mobile nodes existing in the space of a moving body, due to the communication condition or a failure, it can be dealt with.
