The wireless drop the words also mainly include words news a way to drop words and the control letter way to drop words 2 kinds 无线掉话也主要包括话音信道掉话及控制信道掉话两种。
Ms of class b can be connected with gprs and other gsm services and monitor their control channels at the same time . but only one service can be provide at the same time B类ms可以接入gprs和其他gsm服务，同时监控gprs和gsm服务的控制信道，但在某一时刻只能运行一种服务。
18 tobagi f a , kleinrock l . packet switching in radio channels : part ii - the hidden terminal problem in carrier sense multiple - access and the busy - tone solution . ieee trans . communications , dec . 1975 , com - 23 : 1417 - 1433 通过把数据信道和控制信道分离， rmac不仅极大地提高了数据组播的可靠程度，而且明显地提高了对数据信道的利用率。
14 sun m t , huang l , arora a , lai t h . mac layer multicast in ieee 802 . 11 wireless networks . in proc . the international conference on parallel processing icpp 2002 , 2002 简言之， busy tone是在数据信道之外的一个控制信道上传输的无线信号，因为busy tone仅要求能够被检测出存在与否，所以传输busy tone的控制信道只需要占用很小的带宽。
Be can see by the above formula , only lower the obstructive rate of the words news way and control letter way , then can effectively raise a wireless connection rate , and raise the whole net words sound connection rate further 由以上公式可以看出，只有降低话音信道和控制信道的拥塞率，才能有效提高无线接通率，并进一步提高整网话音接通率。
Hsupa ( high speed uplink packet access ) is the new technique of r6 , first in this thesis , the hsupa physical layer is introduced in detail . then base on the physical layer technique characteristic , according to the 3gpp simulation requirements and system simulation requirements , the hsupa downlink and uplink can be constructed by using matlab . then the data channel and control channel can be simulated , so the channels performance can be realized , provide the results can be provided to the system simulation , these ground the future practical applications Hsupa ( highspeeduplinkpacketaccess ) ? ?高速上行分组接入就是r6版本中的新技术,本文首先详细介绍了hsupa物理层的技术特征,然后以其技术特点为依据,按照3gpp的仿真需求和系统级的仿真需求,使用matlab构建hsupa的上下行物理层链路,对其数据信道和控制信道进行仿真验证,从而了解信道的性能,为系统仿真提供仿真数据,为以后的实际应用打下基础,达到预研的目的。
