For ultra high speed packet mobile network, we have proposed a virtual cellular system. Multi-hop route construction algorithm and radio resource allocation are important technical issues of virtual cellular system. Our study is summarized below.1. Study of multi-hop route construction of virtual cellMulti-hop route construction algorithm based on the minimum transmit power criterion was proposed. To further reduce the route total transmit power, multi-hop maximal ratio combining (MHMRC) diversity was proposed and the power reduction by MHMRC diversity was evaluated by computer simulation. We also proposed a table-driven route reconstruction algorithm in order to reconstruct the multi-hop route rapidly when a link or port failure occurs.2. Study on resource assignment of virtual cellAn on-demand channel assignment strategy, using the channel segregation dynamic channel allocation (CS-DCA) algorithm, was proposed for multi-hop link among mobile terminal~wireless port~central port. Due to decreased transmit power in the multi-hop links, the decreased interference leads to less blocking probability compared to present cellular network. A call is blocked when there is no channel available at one link over the multi-hop route. To avoid the call blocking, a relay skipping method was proposed. The impact of the proposed method on the blocking probability was evaluated.3. Study on 2-hop virtual cellIn order to shift from an existing cellular system easily, the number of hops may be limited to 2. The impact of the distribution of wireless ports on the outage probability, the resource assignment algorithm and the throughput performance of 2-hop virtual cellular system were studied.

针对超高速分组移动网络，我们提出了一种虚拟蜂窝系统。多跳路由构建算法和无线资源分配是虚拟蜂窝系统的重要技术问题。我们的研究总结如下。提出了基于最小发射功率准则的多跳路由构建算法。为了进一步降低路由总发射功率，提出了多跳最大比组合（MHMRC）分集，并通过计算机仿真评估了MHMRC分集对路由总发射功率的影响。为了在链路或端口发生故障时快速重建多跳路由，我们还提出了一种表驱动的路由重建算法。针对移动终端~无线端口~中心端口之间的多跳链路，提出了一种基于信道隔离动态信道分配（CS-DCA）算法的按需信道分配策略。与现有蜂窝网络相比，由于多跳链路的发射功率降低，干扰减少导致阻塞概率降低。当在多跳路由上的一个链路上没有可用的信道时，调用被阻塞。为了避免呼叫阻塞，提出了一种中继跳过方法。评价了该方法对阻塞概率的影响。2跳虚拟蜂窝的研究为了方便地从现有蜂窝系统转移，可以将跳数限制为2。研究了无线端口分布对2跳虚拟蜂窝系统的中断概率、资源分配算法和吞吐量性能的影响。
