摘　　要：提出了一种成组进行位置管理的策略,分析了彼此临近的移动台组成一个自组织网的基本网络模型,提出了向中继点注册,由中继点进行信令压缩,组成组控制信令,成批向网络报告位置的位置更新的策略;采用M/M/n/n模型具体比较了批处理方案与传统方案的性能,说明作者的方案不仅减少了移动台的发射功率,还大量节省了频率资源,增加了系统的吞吐能力。The group location update scheme in which a group location update was performed by a leader mobile terminal instead of individual update by every normal mobile terminal has been proposed. A stochastic service system model was also built to analyze the group location update scheme arid individual location update scheme in the view of channelaccess cost. Compared with individual location update scheme, group location update scheme obviously increases channel capability and system throughput due to a significant reduction in signaling cost per update and the number of location updates. As user mobility increases or the number of users in the group increases, the advantage of the group update scheme improves.
