Description
ところが、訪問者は、久しぶりに会う昔の友人であるとする。この場合、あまりのなつかしさと、久しぶりに出向いてくれたという感激とから、訪問者とのコミュニケーションに没頭してしまう場合がある。電話を保留していたことを忘れてしまい、そのことに気付いたときは、すでに回線が切断されていて、再度電話しても、電話の相手は機嫌を悪くして応答してくれないという悲劇を起こしかねない。
そのような場合、保留された者は、回線が切断されているからといって身勝手な行動を取らず、第三者からの着呼に応答することと第三者に対して発呼することとを差し控える必要がある。もし、保留された者がそのような行動を取らなければ、保留した者が保留された者を放置するような上述の状況とは逆であって、「度々電話したけれども、全然連絡が取れない」という保留した者の気分が悪くなるような状況が生じる。このような状況も、配慮に欠ける行動から生じたものであり、日常の雑談程度である電話のコミュニケーションにおいて生じやすい。

図5は、インターネット104上において、通信端末110Aと、通信端末110Aと同様の構成を持つ通信端末との間で送受信されるデータであるメッセージデータの一覧を示す図である。図5を参照して、メッセージデータには、通話の再開が可能であるか否かの状態が遷移したことを他の通信端末に通知するための、「CHG_STAT」と呼ぶメッセージデータと、他の通信端末に通話の再開を要求するための、「REQUEST」と呼ぶメッセージデータと、他の通信端末からCHG_STAT及びREQUESTのいずれかを受信したことに応答して、受信したことを当該他の通信端末に通知するための、「OK_REPLY」と呼ぶメッセージデータとがある。
図6~図10は、通信端末110Aで実行されるプログラムの制御構造を示すフローチャートである。このプログラムを実質的にコンピュータである制御部200が実行することにより、通信端末110Aの機能が実現される。
図1~図10を参照して、上記した構成を持つ本実施の形態に係る通信端末110Aは以下のように動作する。なお、これに先立ち、システム変数記憶部216の変数PVにはセッションの有効時間幅が予め記憶されているものとする。
通信端末110Aの利用者が、初期状態において電話端末116Aに対して発呼を行なうものとする(図6に示すステップ256においてYES)。当該利用者は、テンキー158を押下することによって電話端末116Aの電話番号を通信端末110Aに入力し、通信端末110Aは、入力された電話番号を変数CALLTNOに代入する(図7に示すステップ302)。通信端末110Aは、電話端末116Aに発呼し(図7に示すステップ312)、電話端末116Aから応答があるか(図7に示すステップ314)、又は、通信端末110Aの利用者によって切断ボタン160が押下される(図7に示すステップ316)まで待機する。
初期状態において、通信端末110Bから通信端末110Aへの着呼があるものとする。
リダイヤル待機状態における、通信端末110Aの動作について述べる。通信端末110Aにおいて、変数HISTNO、変数MYSTAT、変数RDF、変数HISSTAT、及び変数STの値は、それぞれ通信端末110Bの電話番号、1、1、1、及びセッションが確立された時刻であり、第1のLED154及び第2のLED156の両方の点灯色は青色であるものとする。
変数HISSTATの値が1であって(通信端末110Bが通話を再開することが可能である。)、通信端末110Aの利用者が、セッションの有効時間を過ぎるまでの間に、電話端末116Aに対して発呼を行なうものとする。通信端末110Aにおいて、変数HISTNO、変数MYSTAT、変数RDF、変数HISSTAT、及び変数STの値は、それぞれ通信端末110Bの電話番号、1、1、1、及びセッションが確立された時刻であり、第1のLED154及び第2のLED156の両方の点灯色は青色であるものとする。
以上の説明から明らかなように、本実施の形態に係る通信端末110Aを利用することにより、通信端末110Aと通信端末110Bとが通話を一旦中断した後、通信端末110Aの利用者が通信端末110Aを用いて第三者と通話する場合、通信端末110Aは、CHG_STATを通信端末110Bに送信して、通話を再開することが不可能であることを通信端末110Bに通知する。したがって、通信端末110Bの利用者は、通信端末110Aの利用者が現在忙しくて通話を再開できないことを認識することができ、通話を中断している間、通信端末110Bの利用者の気分を害することはない。その間、通信端末110Bの利用者が他の端末と通話をするか否かは、当該利用者の自由である。
上記の実施の形態では、通信端末110及び電話端末116は携帯電話であったが、本発明はそのような実施の形態には限定されず、PHS(Personal Handyphone System)及びPDA(Personal Digital Assistant)等の個人用携帯情報端末でも良い。
