GSM 全球移動通信業務已經覆蓋了全世界的大部分地區。如今，基于GSM 業務的
數據傳輸日漸流行，現代化通信設備的應用使遠程醫療成為可能。通過現代化的傳輸設備，醫院可以利用救護車開展遠程緊急醫療救助服務。救護車不但可以提供象醫院門診一樣的服務，甚至可以開展一些小型的外科手術。如果需要交互的信息量不大的話，通過傳統移動電話提供的語音服務就可以滿足通信需要。但是由于帶寬窄，象CT 掃描圖像的傳輸和病人實時的影像傳輸該如何解決呢？本文提出利用GPRS 承載WAP 協議，提供移動設備間的高速、寬帶通信方式，完成以上數據的傳輸。通過研究證明：在目前的移動設備間傳輸數據，無論在速度上、實時性、可靠性上，GPRS 都是最好的承載方式。

EMERGENCY MEDICAL COMMUNICATION SYSTEM BASED ON GPRS
Zhang Jing School of Electronic Information and Automation, Chongqing Institute of Technology, Chongqing, China E-mail: zhjingcq@vip.sina.com Abstract: Global Mobile Communications (GSM) services currently cover almost all parts of the world. The data transfers through GSM services is becoming popular today. Improvements in the modern transportation infrastructure have made it possible for hospitals to deploy ambulances to deal with emergencies at remote areas. These vehicles are capable of providing as much assistance as a conventional clinic, and if needed, even minor surgeries can be done. Voice communication over a conventional mobile handset is sufficient if the information relayed is small, but what about the transfers of bandwidth-hungry data like Computed Tomography (CT) scans and real-time video of the patient's situation? In this paper, we propose the use of the General Packet Radio Service(GPRS) bearer for Wireless Application Protocol(WAP) to provide high-bandwidth communication to the mobile units, which will enable such data transfers. A feasibility study has been done with existing mobile units; and it was found that GPRS is the optimum bearer in terms of speed, immediacy and compatibly with the existing infrastructure.
