基于SOAP协议移动终端的实现和应用

Implementation and Application of Mobile Terminals Based on SOAP Protocol

为解决企业的业务即时提醒问题,采用西门子公司的TC35芯片设计了移动终端硬件系统。该移动终端的硬件电路包括语音、数据传输、短信和传真功能,对外提供RS-232接口,支持标准AT(Attention)指令集。为解决系统的兼容性,软件采用SOAP(S imp le Ob ject Access Protocol)协议,分3层实现了短信接口功能,并利用W SE(W eb Services Enhancem ents)技术保证了系统的安全性。结果表明,基于SOAP协议的移动终端接口简单,系统具有很好的兼容性,能够穿透防火墙,解决了OA系统与短信应用相结合是接口不兼容问题。由于采用了分层的软件设计方式,系统具有很好的扩展性。同时以工作流的短信即时提醒为例,说明了移动终端的具体应用。该应用具有推广价值,如新邮件提醒、新任务提醒和待办任务提醒等。

In order to meet the needs of instant prompt in enterprise, the mobile terminal is designed adopting core TC35 chip of Siemens. It provides radio connection for voice, data transmission, short message and fax. The mobile terminal has a RS-232 asynchronous interface and can be manipulated by standard AT command set. For the sake of compatibility, the short message interface is implemented based on SOAP （ Simple Object Access Protocol ）, and WSE （Web Services Enhancements） is adopted to fulfil the security in our system. The result indicated that the mobile terminal interface based on SOAP is simple. It has solved the interface incompatible problem when OA and the short message application unifies and can penetrate the firewall. The system has the good extension because of the hierarchy software design method is used. Aand a mobile terminal application of workflow instant prompt is also given. This kind of application can be used widely, for example new email instant prompt, new task instant prompt and waiting processing duty instant prompt etc.
