【0001】 [0001]

【発明の属する技術分野】本発明は移動通信システムとそのチャネル切替方法に関し、特に使用中の通話チャネルを通話に支障を与えることなく強制的にチャネルを切替えを行うことができる移動通信システムとそのチャネル切替方法に関する。 The present invention relates to the mobile communication system relates to the channel switching method, a mobile communication system capable of performing forced switch the channel without causing any trouble in particular communication channel in use in the call that for the channel switching method.

【0002】 [0002]

【従来の技術】この種の従来の移動通信システムとそのチャネル切替方法について図面を参照して説明する。 BACKGROUND ART will be described with reference to the drawings a conventional mobile communication system of this kind and its channel switching method.

【0003】図4は従来の移動通信システムの一例を示すブロック図である。 [0003] FIG. 4 is a block diagram showing an example of a conventional mobile communication system.

【0004】図4において、この従来の移動通信システムは、特開昭63−159529号公報の開示内容を示し、移動端末104が無線基地局101を経由して交換局103の制御の基に公衆電話網105に繋がっており、この時の通話路は通話路135を使っているものとする。 [0004] In FIG. 4, the conventional mobile communication system indicates the disclosure of JP-A-63-159529, the public under the control of the mobile terminal 104 is the mobile switching center 103 via the radio base station 101 and connected to the telephone network 105, a speech path at this time is assumed that using the speech path 135.

【0005】交換局103が、無線基地局101との間の通話路135の使用率が成る基準値以上になったことを検出すると、交換局103は無線基地局101のリモートプロセッサ114に対して強制通話チャネル切替え指示オーダaを送出する。 [0005] switching center 103 detects that equal to or greater than the reference value utilization of communication path 135 between the radio base station 101 is made, the switching center 103 is a remote processor 114 of the radio base station 101 forced speech channel switch sends an instruction order a.

【0006】無線基地局101は移動端末の通話レベルを測定し、交換局103で指示された通話レベルより低い移動端末104をさがしだすと、移動端末104の通話チャネル切替え要求オーダbを交換局103の通信制御装置132に送出する。 [0006] The radio base station 101 measures the call level of the mobile terminal, the mobile switching center when locating a mobile terminal 104 is lower than the call level indicated at 103, switching center 103 a call channel switch request order b of the mobile terminal 104 and it sends to the communication control device 132. これは、通話チャネルを他の無線基地局へ切替えれば通話レベルが高くなるとの期待のもとになされるものである。 This is what is made the communication channel based on the expectation that the call level be switched to another radio base station is increased.

【0007】交換局103は、従来技術通り移動端末1 [0007] The exchange station 103, the prior art as a mobile terminal 1
04を無線基地局102に切替えた時、通話可能であることを判定し、通話路135から通話路136へ強制的に通話チャネルの切替えを行う。 04 when switching to the radio base station 102 determines that it is possible call to force a traffic channel switching from the call path 135 to the communication path 136.

【0008】 [0008]

【発明が解決しようとする課題】この従来の移動通信システムとそのチャネル切替方法では、強制通話チャネル切替えを実行すべき最適な移動端末を無線基地局にて選択することにより、不要なチャネル切替えによる無線基地局と交換局との信号路の輻輳を緩和することができるが、無線基地局側の設備の機能強化などが目的でやむを得ず一時的にその機能を停止せざるを得なかった場合に、”保守規制”で規制以後該当装置を使用しての呼接続処理は禁じていたものの、当該装置内に存在する通信呼については移動させる等の救済方法がなく、長時間存在する通信呼により機能強化の作業が円滑に行うことができず、以後通信しようとするユーザーに支障をきたしていたという問題点があった。 BRIEF Problem to be Solved] In this conventional mobile communication system that channel switching method, by selecting the optimum mobile terminal to execute the switching force speech channel in the radio base station, by switching unwanted channels If it is possible to alleviate congestion of the signal path between the radio base station and switching center, etc. enhancements of the radio base station equipment has no choice but to stop the forced temporarily its function for the purpose, "maintenance regulation" regulation after appropriate device although forbids the call connection processing by using at no remedy such move is for communication call that exists within the system, functions by communication call existing long can not be the work of strengthening is carried out smoothly, there is a problem that had hindered the user who is trying to communicate thereafter.

【0009】その理由は、例えば、機能強化等が目的のシステム停止の場合、保守規制を実施した上で該当装置内に通信呼が皆無となった後に停止させるが、上記規制を実施以後は該当無線基地局側設備が保守扱いとなり、 [0009] The reason is, for example, if enhancements like can stop the system of interest, the communication calls in a corresponding device maintenance regulation after having performed is stopped after reaching completely eliminated, the corresponding implementation since the regulatory radio base station equipment becomes a maintenance treatment,
移動局はその存在を無視する事になるため、最悪の場合待ち受けに入ることもできない。 Since the mobile station to be able to ignore its presence, not even to enter the waiting in the worst case.
