Communication system in passenger and freight transporting means

Abstract

Amobile terminal UE accesses a CN and utilizes the Internet via a base station (Node-B) . When riding an electric train, the mobile terminal UE receives a disembarkation notification and an embarkation notification from a RFID tag writer equipped on a train, and notifies the base station Node-B that the terminal is on-board the train. While on-board the train, the terminal accesses an in-vehicle AP by employing a WLAN, Bluetooth, or similar system, and the in-vehicle AP communicates with the base station (Node-B) . This configuration enables the in-vehicle AP to handle all of the mobile devices existing on a train in a centralized manner, thereby eliminating the need for each of the mobile devices to individually access the base station (Node-B).

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...

AI Technical Summary

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.
