Abstract

PROBLEM TO BE SOLVED: To provide a radio communication system and a radio communication method that increase a possibility of receiving incoming call notice from a base station in the case where an intermittent reception cycle is long.SOLUTION: A radio communication system comprises a base station device 20 and a radio terminal 10 that receives intermittently. The base station device 20 re-transmits an incoming call notice when there is no response to the incoming call notice destined to the radio terminal 10. When transmitting an incoming call notice to another radio terminal, the base station device 20 transmits the incoming call notice setting identification information on the radio terminal 10 not having responded to the retransmission in a notification region of the incoming call notice. If identification information set in the notification region of a received incoming call notice is itself, the radio terminal 10 shortens the interval of intermittent reception.

Description

本発明は、無線通信システムおよび無線通信方法に関する。   The present invention relates to a wireless communication system and a wireless communication method.

現在、自動販売機などの機器管理を遠隔から制御するテレメタリングという技術が使われている。詳細には、自動販売機の在庫管理、ガスメータの読み取り、無人駐車場の発券・料金精算機などに、専用のＰＨＳ端末を接続することで、機器のデータ収集やメンテナンスのセンター管理が可能になっている。   Currently, a technology called telemetering that remotely controls the management of equipment such as vending machines is used. Specifically, by connecting a dedicated PHS terminal to vending machine inventory management, gas meter reading, unmanned parking lot ticketing and fee settlement machines, it becomes possible to collect equipment data and manage the maintenance center. ing.

一方、現在のＰＨＳ端末は、基地局に対して１．２秒の間欠受信を行い着信の待ち受けを行うが、電力消費対策などを踏まえて、今後、間欠受信の周期を２１．６秒にした専用のＰＨＳ端末が考えられている。   On the other hand, the current PHS terminal performs 1.2 second intermittent reception to the base station and waits for incoming calls, but taking into account power consumption measures, the intermittent reception cycle will be 21.6 seconds in the future. Dedicated PHS terminals are being considered.

なお、間欠受信に関する従来の技術については、特許文献１に記載されている。   A conventional technique related to intermittent reception is described in Patent Document 1.

特開２００８−２１１６２８号公報JP 2008-21628 A

しかしながら、間欠受信の周期を２１．６秒にすると、間欠受信タイミングが長いため、端末が基地局からの着呼通知を受信することができない可能性が高くなり、着呼通知の再送が繰り返しなされても、着呼通知の再送が、次の受信タイミング前に停止されてしまう恐れもある。   However, if the intermittent reception cycle is set to 21.6 seconds, the intermittent reception timing is long, so that there is a high possibility that the terminal cannot receive the incoming call notification from the base station, and retransmission of the incoming call notification is repeated. However, the retransmission of the incoming call notification may be stopped before the next reception timing.

そこで、本発明は、このような問題を解決するためになされたもので、間欠受信の周期が長い場合において基地局からの着呼通知を受信する可能性を高める無線通信システムおよび無線通信方法を提供することを目的とする。   Accordingly, the present invention has been made to solve such a problem, and provides a wireless communication system and a wireless communication method that increase the possibility of receiving an incoming call notification from a base station when the period of intermittent reception is long. The purpose is to provide.

本発明の無線通信システムは、前記基地局装置と、間欠受信する無線端末とを備えた無線通信システムにおいて、前記基地局装置は、前記無線端末宛の着呼通知に応答がなかったとき、他の無線端末に着呼通知を送信する際、前記応答がなかった前記無線端末の識別情報を着呼通知の通知領域に設定して着呼通知を送信し、前記無線端末が、受信した前記着呼通知の通知領域に設定されている識別情報が自己である場合、間欠受信の間隔をより短くするよう構成される。   The wireless communication system of the present invention is a wireless communication system including the base station device and intermittently receiving wireless terminals. When the base station device does not respond to an incoming call notification addressed to the wireless terminal, When the incoming call notification is transmitted to the wireless terminal, the identification information of the wireless terminal that has not responded is set in the notification area of the incoming call notification, and the incoming call notification is transmitted. When the identification information set in the call notification notification area is self, the interval of intermittent reception is configured to be shorter.

また、本発明の無線通信システムは、基地局装置と、間欠受信する無線端末とを備えた無線通信システムにおいて、前記基地局装置は、前記無線端末宛の着呼通知に応答がなかったときには着呼通知を再送し、前記基地局装置は、他の無線端末に着呼通知を送信する際、前記再送に応答しなかった前記無線端末の識別情報を着呼通知の通知領域に設定して着呼通知を送信し、前記無線端末が、受信した前記着呼通知の通知領域に設定されている識別情報が自己である場合、間欠受信の間隔をより短くするよう構成される。   The radio communication system of the present invention is a radio communication system comprising a base station apparatus and a radio terminal that receives intermittently, and the base station apparatus receives an incoming call notification addressed to the radio terminal when there is no response. When the base station apparatus retransmits the call notification and transmits the incoming call notification to another wireless terminal, the base station apparatus sets the identification information of the wireless terminal that has not responded to the retransmission in the notification area of the incoming call notification. When the identification information set in the notification area of the received incoming call notification is self, the interval of intermittent reception is further shortened.

本発明の無線通信方法は、基地局装置と、間欠受信する無線端末とを備えた無線通信システムの無線通信方法において、前記基地局装置は、前記無線端末宛の着呼通知に応答がなかったとき、他の無線端末に着呼通知を送信する際、前記応答がなかった前記無線端末の識別情報を着呼通知の通知領域に設定して着呼通知を送信するステップと、前記無線端末が、受信した前記着呼通知の通知領域に設定されている識別情報が自己である場合、間欠受信の間隔をより短くするステップとを含む。   The wireless communication method of the present invention is a wireless communication method of a wireless communication system including a base station device and intermittently receiving wireless terminals. The base station device did not respond to an incoming call notification addressed to the wireless terminal. When transmitting an incoming call notification to another wireless terminal, setting the identification information of the wireless terminal that has not responded in the notification area of the incoming call notification and transmitting the incoming call notification; and And when the identification information set in the notification area of the received incoming call notification is self, the step of shortening the interval of intermittent reception is included.

以上のように構成された無線端末１０および基地局装置２０の動作について図面を用いて説明する。   Operations of the radio terminal 10 and the base station apparatus 20 configured as described above will be described with reference to the drawings.

図３は、本発明の実施例に係る無線通信システムの動作例を示すシーケンスである。   FIG. 3 is a sequence showing an operation example of the radio communication system according to the embodiment of the present invention.

まず、例えばセンターから無線端末１０に対し呼が生起し、呼設定が基地局装置２０に要求される（Ｓ１）。   First, for example, a call is generated from the center to the radio terminal 10, and call setting is requested from the base station apparatus 20 (S1).

基地局装置２０は、呼設定の要求に応じて、着呼通知するためのＰＣＨスロットを送信する（Ｓ２）。   In response to the call setting request, the base station apparatus 20 transmits a PCH slot for notification of an incoming call (S2).

無線端末１０は、周期を２１．６秒にした間欠受信を行っている。無線端末１０は、この間欠受信後に、着呼通知するためのＰＣＨスロットが送信されるが、間欠受信後であるため、受信できない。   The wireless terminal 10 performs intermittent reception with a cycle of 21.6 seconds. After the intermittent reception, the wireless terminal 10 transmits a PCH slot for notification of an incoming call, but cannot receive because it is after the intermittent reception.

その後、基地局装置２０は、着呼通知の再送を行う（Ｓ３〜Ｓ５）が、無線端末１０が受信中でないため、再送は破棄される。   Thereafter, the base station apparatus 20 retransmits the incoming call notification (S3 to S5). However, since the wireless terminal 10 is not receiving, the retransmission is discarded.

ここで、別の無線端末に対し呼設定が基地局装置２０に要求されたとする（Ｓ６）。このとき、図４に示すように、基地局装置２０は、再送中に応答しなかった無線端末１０のＰＳＩＤ（自己の識別子）をＰＣＨスロットの通知領域に設定し、それから、着呼通知のＰＣＨスロットを送信する（Ｓ７）。   Here, it is assumed that call setting is requested from the base station apparatus 20 to another wireless terminal (S6). At this time, as shown in FIG. 4, the base station apparatus 20 sets the PSID (own identifier) of the wireless terminal 10 that has not responded during retransmission in the notification area of the PCH slot, and then the PCH of the incoming call notification The slot is transmitted (S7).

無線端末１０は、間欠受信中にこのＰＣＨスロットを受信し、自分宛の着呼ではないが、通知領域に自分のＩＤがあることを認識し、間欠受信のタイミングを１．２秒の間隔になるよう変更する（制御部１６は通知領域に自分のＩＤがある場合は間欠受信のタイミングを短くする）。   The wireless terminal 10 receives this PCH slot during intermittent reception, recognizes that it is not an incoming call for itself, but has its own ID in the notification area, and sets the timing of intermittent reception to an interval of 1.2 seconds. (The control unit 16 shortens the timing of intermittent reception when its ID is in the notification area).

その後、無線端末１０に対し呼が生起し、呼設定が基地局装置２０に要求される（Ｓ８）。   Thereafter, a call is made to the radio terminal 10, and call setting is requested from the base station apparatus 20 (S8).

基地局装置２０は、呼設定の要求に応じて、着呼通知するためのＰＣＨスロットを送信する（Ｓ９）。無線端末１０は、間欠受信のタイミングを短く変更したため、次に着呼通知があっても受信できる。   In response to the call setting request, the base station apparatus 20 transmits a PCH slot for notification of an incoming call (S9). Since the wireless terminal 10 has changed the timing of intermittent reception to be shorter, it can receive even if there is a next incoming call notification.

以上説明したように、本実施例に係る無線通信システムは、基地局装置２０は、無線端末１０宛の着呼通知に応答がなかったとき、他の無線端末に着呼通知を送信する際、応答がなかった無線端末１０の識別情報を着呼通知の通知領域に設定して着呼通知を送信し、無線端末１０が、受信した着呼通知の通知領域に設定されている識別情報が自己である場合、間欠受信の間隔をより短くするため、間欠受信の周期が長い場合において基地局からの着呼通知を受信する可能性を高めることができる。   As described above, in the wireless communication system according to the present embodiment, when the base station apparatus 20 does not respond to the incoming call notification addressed to the wireless terminal 10, when transmitting the incoming call notification to another wireless terminal, The identification information of the wireless terminal 10 that has not responded is set in the notification area of the incoming call notification and the incoming call notification is transmitted. The identification information set in the received notification area of the incoming call notification is self-identified. In this case, since the interval of intermittent reception is made shorter, it is possible to increase the possibility of receiving an incoming call notification from the base station when the intermittent reception cycle is long.

これに対し、図５の従来の無線通信システムの動作例では、Ｓ７で、着呼通知のＰＣＨスロットを受信しても、間欠受信のタイミングを変更しないため、次に着呼通知（Ｓ８）を受信できない。   On the other hand, in the operation example of the conventional wireless communication system of FIG. 5, even if the PCH slot of the incoming call notification is received in S7, the timing of intermittent reception is not changed, so the incoming call notification (S8) is performed next. Cannot receive.
