| 摘 要： | 在分析蜂窝系统信道分配问题的基础上,提出一种适用于语音、数据呼叫的蜂窝移动通信系统的信道分配策略.该策略将信道分为3部分:数据信道、语音新呼叫保护信道和语音切换呼叫保护信道,为语音新呼叫和语音切换呼叫分配保护信道以降低呼叫阻塞率.为了进一步提高系统承载的语音业务量,赋予语音呼叫抢占优先权,语音呼叫可以抢占数据信道;语音...

| Abstract: | A channel assignment strategy of voice/data call for cellular mobile communication system was proposed on the basis of analysis of channel assignment of that system.In this strategy the channel was divided into three parts: data channels,new voice call guard channels and handoff voice call guard channels.The guard channels for new voice calls and handoff voice calls were used to reduce their blocking probability.To further improve the voice traffic in the system,voice calls took preemptive priority and coul... |
