| Summary: | 碩士 === 國立中興大學 === 資訊科學與工程學系所 === 97 === With the incredible development of the network technologies and the rapid increase of network bandwidth, Voice over Internet Protocol (VoIP) is a promising technology that attracts lots people’s attention. Many telecommunication companies have also engaged in the development of VoIP products and applications.
In this thesis, we utilize the SIP phone technology to implement a mobile voice-guiding in exhibition halls or museums. Firstly, we implement a guiding device that uses the IEEE 802.11 wireless network as the transmission media and utilizes the SIP technology as the call signaling mechanism to setup a call connection. Consequently, requesting the guiding voice data is similar to dial-up a telephone call. The users can dial the number of each exhibition by his/her guiding device. Then, through the IP-PBX (IP Private Branch Exchange) device, a SIP signaling connection is setup between the guiding device and the IVR (Interactive Voice Systems) systems. Once the IVR receives the number, it accesses the database server to request the voice-guiding audio file according to the languages selected by visitors. Finally, the audio-file is transmitted to and played by the guiding device. Notably, to facilitate the management of guiding devices, we also implement a web-based software for renting and returning the guiding devices.
We have implement a prototype system and show that our system can work fine as well. The result shows that SIP technology can be successfully applied in the mobile voice guiding systems.
