Problems solved by technology

[0005]However, in order to realize NEMO, it is necessary to distinguish whether the mobile device is in the vehicle or leaves it from the vehicle, but this is not judged in the existing location registration system, the existing The communication unit in the vehicle only corresponds to 3GPP, so there is a problem that power consumption does not change compared to when it is outdoors, etc.

Embodiment Construction

[0043] In this specification, a vehicle of a bus, a fuselage of an airplane, a hull of a ship, a vehicle of a train, a vehicle of an automobile, and the like are collectively referred to as a vehicle. In addition, the wireless network in the vehicle will be described below as WLAN, but Bluetooth can also be applied, and other systems can also be applied. In addition, in this specification, 3GPP is used as an example to describe the mobile communication system, but the present invention is not limited to the mobile communication system conforming to 3GPP, and may conform to other standards (specifications).

[0044] FIG. 1 is a diagram illustrating the configuration of a communication system according to an embodiment of the present invention.

[0045] The system of the embodiment of the present invention consists of a mobile device (UE), an area where multiple mobile devices move simultaneously (such as vehicles such as trams), a wireless IC tag (RFID tag), a wireless IC tag r...

Abstract

A mobile terminal (UE) accesses a CN via a normal base station (Node-B) and utilizes the Internet. When entering the train, it receives the notification of leaving and entering the train from the RFID tag writer installed on the train, and notifies the base station (Node-B) that it has entered the train. In the train, use WLAN or Bluetooth, etc., to access the on-board AP, and the on-board AP communicates with the base station (Node-B). By doing so, it is possible to collectively use the on-vehicle AP for all the mobile devices located in the train, so that each mobile device does not need to access the base station (Node-B) individually.

Description

technical field [0001] The present invention relates to a communication system that uses wireless waves in means for transporting passengers and goods (hereinafter referred to as vehicles) such as buses, airplanes, ships, and trains, such as mobile communication devices. Background technique [0002] In the current position registration system, when multiple mobile machines are located in vehicles such as trams and buses, and these mobile machines pass through the position registration area and move together with the vehicle, if all the mobile machines with the vehicle When each mobile device registers its location with the network, congestion occurs in the wireless environment. [0003] In order to avoid this situation, when crossing the location registration area, the location registrations of multiple mobile devices are grouped into one location registration. This way of thinking is collectively referred to as NEMO (NetworkMoving). [0004] In addition, there are not on...
