【発明の属する技術分野】
本発明は、基地局装置と通信端末装置との間の通信状態を基地局装置が認識する通信端末装置、基地局装置ならびに無線通信システムに関するものである。
【0002】

【発明が解決しようとする課題】
しかしながら、このような従来の無線通信システムの通信状態検出方法では、無線通信の状態を見るために定期的に無線通信(ポーリング)を行う必要がある。
【0006】
また、無線通信を行う通信端末装置と基地局装置とがそれぞれ通信状態を認識するためには、両装置とも定期的に無線通信を行う必要がある。また、両装置間で同時に通信状態を認識することは、前記定期的に行う無線通信の周期を正確に両装置の間で一致させる必要があるが、実現容易ではない。
【0007】
また無線通信が周囲の状況によって一時的に遮断され、復旧する余地がある場合でも、ポーリングでは異常が発生したものと誤認識してしまう恐れがあるという問題があった。
【0008】
本発明は斯かる実情に鑑み、ポーリングを行なうことなく通信状態を検知でき、無線通信を行う通信端末装置と基地局装置とがそれぞれ通信状態を認識することができ、一時的に遮断され、復旧する余地がある場合に異常が発生したものと誤認識してしまうことのない通信端末装置、基地局装置ならびに無線通信システムを提供するものである。

【0010】
この構成により、第1の通信手段の通信状態を検知して、第2の通信手段により基地局装置に通知するので、ポーリングを行なうことなく、また、一時的に遮断され、復旧する余地がある場合に異常が発生したものと誤認識してしまうこともなく、基地局装置に応用動作の開始や終了を行なわせることができる。
【0011】
また、本発明の通信端末装置は、通信状態検知手段で、第1の通信手段が通信エリアに進入したことを検知した場合に、通信状態を通知する構成を有している。この構成により、通信端末装置は、基地局装置に第1の通信手段との通信開始時期を知らせることができる。
【0012】
また、本発明の通信端末装置は、通信状態検知手段で、第1の通信手段が通信エリアから離脱したことを検知した場合に、通信状態を通知する構成を有している。この構成により、通信端末装置は、基地局装置に第1の通信手段との通信終了時期を知らせることができる。
【0013】
また、本発明の通信端末装置は、通信状態検知手段で、第1の通信手段が受信する基地局装置からの信号の状態と、あらかじめ取得した通信エリアを示す位置データに対する現在位置を測位する現在位置測位手段によって得られた現在位置データの状態と、あらかじめ取得した通信エリアを示す位置データに対する通信端末装置の周辺から取得した情報により得られる位置データの状態のうちの少なくとも一つで検知する構成を有している。
【0014】
この構成により、基地局装置からの信号の状態や、通信エリアの位置データに対する現在位置データの関係や、通信エリアの位置データに対する通信端末装置が存在する周辺からの位置データによって、通信エリアに進入し、通信可能状態になったか、あるいは通信エリアから離脱して通信不能状態となったかを検知することができる。
【0015】
また、本発明の通信端末装置は、通信エリアが、第2の通信手段で基地局装置と通信可能なエリアよりも狭い構成を有している。この構成により、通信エリア境界付近での通信状態を第2の通信手段で確実に基地局装置に通知することができる。
【0016】
また、本発明の基地局装置は、通信端末装置と通信可能な第1の通信エリアを有する第1の通信手段と、第1の通信エリアより広い通信端末装置と通信可能な第2の通信エリアを有する第2の通信手段とを備え、通信端末装置の第1通信エリアに対する通信状態を第2の通信手段で受信する構成を有している。
【0017】
この構成により、基地局装置は、ポーリングを行なうことなく第1の通信手段の通信状態を検知でき、無線通信を行う通信端末装置と基地局装置とがそれぞれ通信状態を認識することができ、一時的に遮断され、復旧する余地がある場合に異常が発生したものと誤認識してしまうこともない。
【0018】
さらに、本発明の基地局装置は、通信端末装置が第1の通信エリアに進入あるいは第1の通信エリアから離脱したことを示す通信状態を第2の通信手段が受信した場合に、通信に関するアプリケーションを実行するアプリケーション実行手段が第1の通信手段と通信端末装置との通信の接続である接続処理、あるいは第1の通信手段と通信端末装置との通信の切断である切断処理を行う構成を有している。
【0019】
この構成により、基地局装置は、ポーリングを行なうことなく第1の通信手段の通信状態を検知し、確実に第1の通信手段での通信端末装置との接続処理、あるいは切断処理を行うことができる。

【0028】
さらに、通信状態検知部102が狭域無線通信エリア内に進入したことを検知する他の方法として、あらかじめ狭域無線通信エリアを示す狭域無線通信エリア位置データを取得しておき、カメラ(図示せず)などを利用して現在位置周辺に記載されている町名番地表示、駅名表示、バス停表示、建物表示といった現在位置を特定できる情報に基づいて、通信端末装置100があらかじめ備えた位置データベース(図示せず)や、広域無線通信部103を介して基地局装置200やネットワークを介して他の位置データベース(図示せず)から、現在位置データを取得し、取得した現在位置データを狭域無線通信エリア位置データに照らし合わせて狭域無線通信エリアに進入したことを検知するようにしてもよい。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a communication terminal device, a base station device, and a wireless communication system in which a base station device recognizes a communication state between the base station device and the communication terminal device.
[0002]
[Prior art]
Conventionally, as this type of communication terminal device, base station device, and wireless communication system, when a base station device periodically performs wireless communication with a communication terminal device, and a change in the communication state occurs, the base station device changes a line communication unit. Some systems have a function of sending a notification to a higher-level device via an external device (for example, see Patent Document 1).
[0003]
In general, an application connected by Transmission Control Protocol / Internet Protocol (TCP / IP), which is a general connection procedure of the Internet, detects whether the communication path is valid by performing a process of transmitting and receiving data. it can. That is, unless data is transmitted / received, it cannot be detected even if the communication path is actually disconnected. Therefore, a means for detecting the state of the communication path by periodically performing communication between applications between the communication terminal apparatus and the base station apparatus is adopted.
[0004]
[Patent Document 1]
JP-A-9-83656 (pages 4-5, FIG. 2)
[0005]
[Problems to be solved by the invention]
However, in such a conventional communication state detection method of a wireless communication system, it is necessary to periodically perform wireless communication (polling) to check the state of wireless communication.
[0006]
In addition, in order for the communication terminal device and the base station device that perform wireless communication to recognize the communication state, both devices need to periodically perform wireless communication. Simultaneously recognizing the communication state between the two devices requires that the period of the periodic wireless communication be exactly the same between the two devices, but it is not easy to realize.
[0007]
In addition, even when wireless communication is temporarily interrupted by surrounding conditions and there is room for recovery, there is a problem that polling may cause a false recognition that an abnormality has occurred.
[0008]
In view of such circumstances, the present invention can detect a communication state without performing polling, and can recognize a communication state between a communication terminal apparatus and a base station apparatus that perform wireless communication, and are temporarily shut down and restored. An object of the present invention is to provide a communication terminal device, a base station device, and a wireless communication system that are not erroneously recognized as having an abnormality when there is room to do so.
[0009]
[Means for Solving the Problems]
A communication terminal device according to the present invention includes a first communication unit that communicates with a base station device, a second communication unit that communicates with a base station device, and a communication area where the first communication unit can communicate with the base station device. And a communication state detecting means for detecting the communication state, wherein the communication state detected by the communication state detecting means is notified to the base station apparatus by the second communication means.
[0010]
According to this configuration, the communication state of the first communication unit is detected, and the base station device is notified by the second communication unit. Therefore, there is room for recovery without being polled and being temporarily cut off. In this case, it is possible to cause the base station apparatus to start or end the applied operation without erroneously recognizing that an abnormality has occurred.
[0011]
Further, the communication terminal device of the present invention has a configuration in which a communication state is notified when the communication state detection unit detects that the first communication unit has entered the communication area. With this configuration, the communication terminal device can notify the base station device of the time at which communication with the first communication unit is started.
[0012]
Further, the communication terminal device of the present invention has a configuration in which, when the communication state detecting means detects that the first communication means has left the communication area, the communication state is notified. With this configuration, the communication terminal device can notify the base station device of the end time of communication with the first communication unit.
[0013]
Also, the communication terminal device of the present invention is characterized in that the communication state detecting means detects the state of the signal from the base station apparatus received by the first communication means and the current position for the position data indicating the communication area acquired in advance. A configuration for detecting at least one of the state of the current position data obtained by the position positioning means and the state of position data obtained from information obtained from the vicinity of the communication terminal device with respect to the position data indicating the communication area obtained in advance. have.
[0014]
With this configuration, the mobile station enters the communication area according to the state of the signal from the base station device, the relationship between the current position data with respect to the communication area position data, and the position data from the vicinity where the communication terminal device exists with respect to the communication area position data. Then, it is possible to detect whether the communication is enabled or the communication area is disconnected and the communication is disabled.
[0015]
Further, the communication terminal device of the present invention has a configuration in which the communication area is smaller than the area in which the second communication means can communicate with the base station device. With this configuration, the communication state near the boundary of the communication area can be reliably notified to the base station device by the second communication means.
[0016]
Further, the base station apparatus of the present invention includes a first communication unit having a first communication area capable of communicating with a communication terminal apparatus, and a second communication area capable of communicating with a communication terminal apparatus wider than the first communication area. And a communication state of the communication terminal device with respect to the first communication area is received by the second communication means.
[0017]
According to this configuration, the base station apparatus can detect the communication state of the first communication unit without performing polling, and the communication terminal apparatus and the base station apparatus that perform wireless communication can recognize the communication state, respectively. It is not erroneously recognized that an abnormality has occurred when there is room for recovery and there is room for recovery.
[0018]
Further, the base station apparatus according to the present invention, when the second communication means receives a communication state indicating that the communication terminal apparatus has entered the first communication area or has left the first communication area, an application related to communication. Application execution means for executing the connection processing which is the connection of the communication between the first communication means and the communication terminal device, or the disconnection processing which is the disconnection of the communication between the first communication means and the communication terminal device. are doing.
[0019]
With this configuration, the base station device can detect the communication state of the first communication unit without performing polling, and can reliably perform the connection process or the disconnection process with the communication terminal device in the first communication unit. it can.
[0020]
