阻塞率
说明: 呼叫阻塞率的计算和仿真:在时间轴上考虑。无论阻塞与否,下一呼叫到达时刻为当前呼叫到达时刻加上服从参数为1/λ的指数分布的呼叫间隔时间。一个呼叫到达时只需要判断呼叫的到达时刻和各个信道服务完成时刻的先后:如果前者比后者中任意一个大,说明至少有一个信道服务完成时刻比此呼叫到达时刻早,即此信道空闲,此时呼叫成功,应该先把此信道下一个服务完成时刻置为当前呼叫到达时刻,再加上服从参数为μ的指数分布的服务时间;反之,如果前者比后者中全部都小,说明所有信道在此呼叫到达后才会结束服务,即当前忙,此呼叫被阻塞掉了(call blocking probability calculation and simulation : the time frame to consider. Whether or not blocked, the next call arrived at the present moment to call time arrived with a subordinate parameters/ index distribution of the call interval. A call arrived only judgment call and the arrival time each channel service has completed a moment : If the former than the latter an arbitrary, and at least one channel is completed service calls than this moment arrived moments earlier, that this channel is idle, call this success, should first get here Channel a moment of complete services for the current call home arrival time, coupled with the parameters obey the exponential distribution services; Conversely, if the former than the latter, all small, with all the Channel call arrived only aft)

GPSGSM
说明: G P S和G S M 双定位终端的软硬件设计与实现
:随着移动定位技术的发展, 单纯的签子G P S 的定位终端或者荃于移动网络的定位终端都将无法浦足用户的俩求。前者的G P S定
位信号受地形及建筑物的影晌,会存在定位盲区 后者定位精度和定位能力受到移动网 络的限制。该文提出一种集成了G P S定位和G S M
网络定位技术的定位终端,阐述了它的软硬件的设计和实现。实验结果表明,该定位终端结合了G P S和G S M网络两种定位方式的优点,(D e s i g n a n d I m p l e me n t a t i o n o f t h e T r a c k i n g T e r mi n a l I n t e g r a t i n g
