The great increase of the number of users requires efficient management of the spectrum. In hierarchical cellular systems based on CDMA, the frequency borrowing resource allocation (FBRA) algorithm is proposed to allocate frequency spectrum more efficiently. This algorithm lends frequency spectrum of macrocell to microcells when mass hot spot occurred. We analyze the interference to signal ratio and reverse link capacity in case of using the proposed algorithm. Based on the result, the algorithm performance is evaluated in view of blocking, the handoff refused probability, and the spectrum efficiency. The numerical result shows that the proposed algorithm can increase the capacity and solve the mass hot spot problem
