摘要(中)

近年來，智慧型手持裝置已具有豐富的感測元件。隨著這些智慧型手持裝置逐漸成長，越來越多手持裝置上的互動式服務應用程式也相繼被開發。使用者想利用手持裝置去控制周邊裝置，同時當某些感興趣的事件發生時，也希望能夠收到通知，因而需要一個有效率的即時通知機制的需求也正在增加。但舊有的架構並不能有效的處理及控制這些即時訊息，亦尚未考慮到未來系統的可擴展性。此外，由於訊息格式不一致，讓開發者難以針對多項服務及舊有的服務做整合。
為了解決這些問題，我們提出了一個以藍牙為基礎針對Android手持裝置開發適合異質性互動服務之即時通知系統。整個系統由三個模組所組成：藍牙連線、AT訊息控制協定、相關服務實作。在設計這些模組時，我們考量到未來開發者要做整合或跨平台的需求，使用設計模式來規劃，並提供介面幫助開發者減少重複開發相同元件並達到系統可擴展性的目的。從本論文的實作中，可以證明新提出的藍牙規範 (profile)可以和原生的藍牙規範共同運作，而所提出的即時通知系統也運作良好。未來，我們將可以利用藍牙科技結合即時通知系統讓生活簡單化、便利化，並達到即時取得第一手資料的目的。

摘要(英)

In near future, with growing usage of smart handheld devices with richer sensing functionalities, more and more interactive service applications have been developed. Users would like to control the peripheral devices using handheld devices and be notified what they are interested. So the demands for the efficiency of real time notification schemes are also increasing. However, legacy frameworks fail to process and control the notification information in as scalable and efficient manner. The notification system for multiple services or legacy services is seldom to be considered due to the difficulties to handle events on different conditions for the service provider to develop.
To address these problems, we propose a real time notification system architecture for heterogeneous interactive services in Bluetooth-based Android handheld devices. It is composed of three essential modules: Bluetooth connection, AT Message Control Protocol (ATMCP), and related service implementation. We also design our architecture with design pattern, provide an interface for future use to achieve better system scalability if the developer wants to integrate more services or meet the requirements of cross-platform.
Our implementation demonstrates that that the proposed new profile in Bluetooth connection module can coexist well with other native Bluetooth profiles and the proposed real time notification system on the Android handheld devices can adapt and perform well. With the proposed real time notification system on Bluetooth, we can make our life easier, more convenient, and keep fresh information in hand.
