摘要
讨论了在切换排队且排队顾客优先的条件下,小区共有有限个个信道和一个缓存区,一部分信道为新呼叫用户和切换用户共享,剩余的信道预留给切换用户使用,缓存区由切换用户使用,新呼叫用户和切换用户均为Poisson到达的通信信道配置模型.得出了稳态时模型中各状态的概率分布,平均排队队长,阻塞率及状态转移速率关系图.
Under the condition of hand off queue and the queuing priority, this paper discussed the communication channel assignment model with finite channels and a buffer; part channels are shared with the new call and the hand off; the rest channel are reserved for hand off , the buffer is specified for queuing; Where both the new call and the hand off are Possion arrival. The state stationary distribution,mean queuing length,blocking rate , and state transition rate relation graph are obtained.
