针对分层网的复杂组网结构的特点，摩托罗拉设计了名为AHA（Advanced Handover Algorithm，先进切换算法）的切换算法，用于分层网（HCS）结构的小区之间的切换。有时也叫“微蜂窝切换算法”。AHA切换算法也就是基于PBGT（功率预算）的算法，在AHA算法中MOTOROLA开发了七种TYPE的算法，可根据不同情况采用相应的算法。-Characteristics of complex network structure of the hierarchical network, Motorola s design called the AHA (Advanced Handover Algorithm. Advanced cut

Exchange algorithm) of the switching algorithm is used to switch between the plot of the structure of the stratification (HCS). Sometimes called "micro-cellular handoff algorithm. AHA

The switching algorithm is based on the algorithm PBGT (power budget), the AHA algorithm MOTOROLA developed seven TYPE algorithm, based on not

With the corresponding algorithm.
