摘要
基于GSM多功能基站的手机终端接入功能,实现其语音通信功能。首先开通基站的语音呼叫业务,然后将原始语音形成语音发送脉冲,最后将手机锁定在基站工作,对语音功能进行测试。根据多功能基站的功能和性能要求,不仅实现其语音通信功能,且使之具有呼叫异常处理能力,功能设计上相对商用基站也作了一些改进。实验证明:锁定在多功能基站工作的手机能收到基站发送的语音信息。
Voice communication function is realized for a multifunctional base station working on GSM networks based on its ability to induce cell phones to work on it. Firstly,voice services system is designed for the station.Then,the function of transferring original voice to voice sending bursts is added to it. Lastly,the station induces a cell phone to work on it to test the voice function. Eventually,the voice communication function with the ability to handle call exception is implemented according to functional and performance requirements of the station. Besides,compared with commercial base station,some improvements have been done. Measured results confirm that the station can send voice to a cell phone working on it.
